s we say goodbye to 2011 and usher in a new year, it is time for most of us reflect on our accomplishments and plan for the year ahead. Hopefully, 2011 has been a year marked by continued improvements both in volume and profitability for all in the industry. This new economic climate is one fraught with wild market swings, uncertainty in global markets and a restrictive financial sector. Navigating this environment has been stressful and challenging for many—terminal for some. However, there are also success stories and optimistic signs for the coming year. What are your plans for 2012? What are your responses to these new and ever-changing challenges we now face? How are you continuing to evolve? What new services, products or value-added components are now being offered by your company? Where do you go to get answers to these questions? Many of you, like me, will look to tradeshows, seminars, training and annual association meetings to find the answers. With 2012 just around the corner, many of you may have already registered for industry-related tradeshows, training seminars and conventions. I have registered for two noteworthy events. The first one is the World of Concrete trade show and exhibition in Las Vegas, Nevada, which runs from January 23–27, 2012. CSDA has been a

co-sponsor of this event for 35 years, and the association will be holding its Board of Directors and Next Generation meetings during the week. CSDA also has two training classes scheduled at World of Concrete. Hand Sawing and Drilling 101 runs January 24–26 while Estimating takes place January 24–25. Aside from meetings and training classes, CSDA will also hold a special WOC event on Wednesday, January 25 to celebrate its 40th Anniversary. Come by the CSDA booth (#C4457) at 10:00 AM to help us celebrate this historic occasion. The second noteworthy event is CSDA’s 40th Annual Convention and Tech Fair, which takes place March 4–9, 2012 at the Sheraton Maui Resort and Spa on Ka’anapali Beach, Hawaii. The convention is loaded with multiple roundtables, workshops and presentations that can help any business thrive and survive. Pre-convention Board and committee meetings will run March 5-6. In addition, the International Association of Concrete Drillers and Sawers will join CSDA in Hawaii to hold its annual meeting on March 6. This year’s convention will truly represent the global community of the professional drilling and sawing industry, and I hope to see you there. Wishing you a safe holiday season full of joy and a prosperous New Year!

Almost 6,900 square feet of concrete was cut to create 10 openings. 6 | D ECEMBER .11

CASES

In February 2012, New York City’s water supply, which also serves suburban Westchester County, will be treated by the world’s largest ultraviolet (UV) light disinfection facility. The facility will treat water from the Catskill and Delaware systems, which provide 90 percent of New York City’s drinking water. Concrete walls needed to be removed to create several large openings at one of the facility’s shaft locations. The speed and accuracy of diamond tool cutting was an ideal match for this work.

hile the current largest UV facility treats around two hundred million gallons per day, the new 250,000-squarefoot Catskill/Delaware UV disinfection facility will have a capacity of more than two billion gallons per day. The facility will enable water quality to meet the U.S. Environmental Protection Agency’s Federal Safe Drinking Water Act and will include 56 UV units, each designed to handle 40 million gallons of water per day. The $1.5 billion facility in Mount Pleasant, New York is being constructed by Skanska USA Civil Northeast/ECCO III Enterprises/J.F White Joint Venture, more commonly known as SEW Construction. The total project, including contracts bid for electrical, HVAC and plumbing, brought the bid cost to $1,336,325,570, the largest public works contract let in the history of Westchester County. The project will require 1.5 million square feet of foundation work and excavation 25 to 45 feet below grade to accommodate pipework up to 12 feet in diameter. In December 2010, CSDA member Atlantic Concrete Cutting, Inc. began concrete cutting work at the site for SEW Construction and anticipates being on the project through the start of 2012. In May 2010, Atlantic was tasked with wire sawing 6,890 square feet of concrete wall to create five 28.5-foot-tall by 9-foot-wide by 6-foot-thick openings and five 14.3-foot-tall by 9-foot-wide by 6-foot-thick openings at one of the facility’s shaft locations. The cutting of the larger openings would create 12 pieces, each weighing 10 tons, while the smaller openings would create six 10-ton pieces. The work plan also included core drilling over 200 access holes for diamond wire to be pulled through and 4-inch-diameter by 6-foot-deep picking holes. w w w.CSDA.ORG

The larger openings were split into 12 pieces, each weighing 10 tons. The work would involve using up to four wire saws per shift to meet the four-week time frame set by the general contractor. To prepare for cutting, Atlantic marked all areas within 20 feet of cutting equipment with red danger tape. Heavy canvas tarps were used to protect

surrounding areas from the accidental breaking of the diamond wire and from slurry spray. The perimeters of the 9-foot by 9-foot work areas inside Shaft 19 Raw & Treated Water Channels were lined with sandbags on the floor. Transparent poly sheeting was hung on

the three open sides of the work area to contain slurry. This way, spray collected on the poly sheeting would drain to the floor and be contained by the perimeter sandbags. “We made sure from the start of our work that we kept a high level of communication with the joint venture,” said Stu Fishman, project manager for Atlantic Concrete Cutting, Inc. “I communicated at least once daily with Marc Caruso, project manager for SEW Construction, regarding job performance, schedule issues, safety questions and any special needs for the day. This helped the cutting work run as smoothly as possible.” The four Plattner GS-150-30 wire saws and gang boxes with equipment were lowered from the top to the lower level of Shaft 19 by crane. Generators were to remain outside of the shaft, away from water channels, so cords were fed down to the work area. Operators began core drilling the wire access holes and rigging holes using DD 500 hi-cycle diamond coring systems supplied by Hilti. Rather than purchasing new drill bits, Atlantic’s John Milcarek was responsible for brazing segments supplied by Diamond Products onto the bits. Two drills were used to create the openings. The bottom holes were drilled first to allow a pump hose to run through and contain waste water. The general contractor provided man lifts for operators to access the upper holes. The contractor made 28 holes at each of the five larger openings and 16 at the five smaller openings. Each 4-inch-diameter hole was drilled through the 6-foot-thick wall and took two hours to complete. On the third day of drilling, Atlantic had enough picking and rigging holes to begin setting up the wire saw pulls for the first two openings. The cutting team placed two saws just inside the openings and the controls just on the outside. The contractor used 0.625-inchdiameter wedge anchors and 0.5-inch dropin anchors to mount the pulley wheels. The wheels were mounted flush to the walls on the outside horizontal cut, to the opening to be cut on the horizontal cuts and the center vertical cut. Because the diamond wire chosen performed so well with the aggregate material, Atlantic only used a total of 400 feet for the entire job. The wire, supplied by K2 Diamond, was pulled through the holes and around the pulleys to set up the runs. The cuts were beveled to allow other subcontractors to remove the concrete sections. At each of the 10 locations, the horizontal cuts were to be completed first followed by the vertical cuts. Operators made five horizon-

The contractor created five smaller openings that were each 14.3 feet tall. tal cuts 9 feet in length for the five large openings and two for the five smaller openings. Each cut through the 6-foot-thick concrete wall took four hours to complete. Once all horizontal cuts were made at one location, one vertical cut was made down the center and two vertical cuts were made flush to the perpendicular walls on the outer edges. For the larger openings, these vertical cuts measured 28.5 feet and for the smaller openings, 14.3 feet. The longer vertical cuts took eight hours to complete while the smaller cuts took just four hours. In total, Atlantic operators were cutting and drilling in two 10-hour shifts daily over 24 days. When cutting was complete, the cut sections of concrete were cleared from the openings. Starting from the top and working down, the 10-ton pieces were rigged for removal before being craned out, each taking 60 to 90 minutes to pull free and lift out from the work area. The cut sections were then demolished. Working at a job location such as a water treatment facility, a number of safety measures were set in place. Some of these safety measures, such as slurry containment, were the responsibility of Atlantic Concrete Cutting. Other safety measures were the responsibility of the facility owners and general contractor, and were in place to make the work area safe for the cutting contractor. Wherever operators

CSDA Company Certification Program

Atlantic Concrete Cutting First to Achieve Level 3 Certification In October, Atlantic Concrete Cutting, Inc. became the first company to achieve Level 3 (ISO 9000 Compliant) Certification through the association’s Company Certification Program. The 3-tier program has been developed so that cutting contractors can provide owners, architects, engineers, general contractors and government officials with a valuable prequalification tool that acknowledges sound business practices. The company’s application was processed before an on-site audit was carried out by the program administrator, Asurency, Inc., to confirm the content of the application and provide approval of Atlantic’s Quality Management System. “We are extremely proud to be awarded CSDA Level 3 Certification”, said Nancy Walker, president and owner of Atlantic Concrete Cutting. “CSDA is to be commended for its efforts and initiative to create a comprehensive company certification program for our industry.” Level 1 Certification has been devised to evaluate that a company meets the basic safety and financial requirements of the industry. To attain Level 2, a company must also show it is undertaking sound operational and financial best practices in addition to the criteria set out for the first level. The company must also provide evidence that it has taken part in basic training or certification programs to better its employees and the company as a whole. To achieve Level 1 or Level 2 Certification, companies must successfully pass a written application review. Level 3 will provide potential customers with proof that a company has a total quality management system in place, and that the contractor is committed to a high standard of safety, training and sound business practices. Level 3 includes an audit with standards equivalent to the internationally-recognized ISO 9000 certification scheme, plus other industry-specific requirements. The CSDA Company Certification Program is available to all sawing and drilling contractors.

were working, a series of corresponding valves, flange connections and roller gates were sealed and checked to make sure no water leaked into, or flooded, the work area. Communication between the cutting team and the site owners was critical. From a personal safety point of view, all members of Atlantic’s team were required to wear all necessary items of personal protective equipment (PPE) while on site, including ventilators, and a chlorine monitoring device was present at all times. The cutting contractor succeeded in wire sawing 6,890 square feet of concrete to create 90 cut sections, each measuring 4.75 feet tall, 4.5 feet wide and 6 feet thick and weighing 10 tons. To create holes for the diamond wire pulls and crane rigging, operators made 220 holes measuring 4 inches in diameter through the 6-foot-thick wall. It took Atlantic operators 24 days to complete the work. The project was completed on time and within budget. “I’m very proud of our men and the skilled wire sawing they performed,” said Nancy L. Walker, president and owner of Atlantic Concrete Cutting, Inc. “Stu Fishman, our project manager, did a great job safely meeting the needs of SEW Construction right on schedule. The cooperation of Marc Caruso and Brett Albert, project managers for SEW, also allowed for smooth completion of our work,” added Walker.

Grooving Through the Night CSDA Members Team Up to Rehabilitate Alaskan Runway

he winters in Alaska can be harsh—not just for its residents, but also for the state’s infrastructure. At a U.S. Air Force base in Fairbanks, Alaska,

drastic variations in seasonal temperatures of around 100°F and extreme winter weather conditions had damaged and deteriorated a 14,530-foot section of concrete runway. The runway required repairs and resurfacing to avoid potentially serious and expensive accidents caused by aircraft losing control on the worn surface. Two CSDA contractor members joined forces to complete this task.

Eielson Air Force Base (AFB) has been in operation since 1944 and is home to the 354th Fighter Wing (354 FW) unit. The base was named after Carl Ben Eielson, who in 1928, together with Hubert Wilkins, was the first man to fly from North America to Europe over the North Pole. The flight departed Barrow, Alaska and landed on the Norweigen island of Spitsbergen. Today, the 354 FW use the location to conduct field training exercises and test flights for aircraft like the F-22 Raptor. Runway 14-32 measures 14,530 feet long with a 75-foot-wide keel section of concrete. The runway is used by fighter aircraft from 354 FW and by large refueling tankers that are based at Eielson AFB. Concrete was chosen for the keel section due to its durability in warm and cold weather conditions compared to other materials. This part of Alaska can experience a variation in temperature from 70°F in the summer to -25°F in the winter, so a material that could withstand this variation, the harsh winter conditions and the process of snow removal by plows, was a necessity. The runway now required grinding to remove the existing grooving before a new grooved surface could be created. In addition, there was a requirement to remove old sealant from the joints of the runway and replace it with new material, which would then be painted. An increasing number of air field runways are being rehabilitated through the process of grinding and regrooving. By having the concrete

or asphalt surface on a runway changed using specialized diamond grinding and grooving machines, these air fields can greatly reduce aircraft braking distances by providing channels for water to run off the surface. This also reduces the risk of aircraft hydroplaning on runways. Depending on the type of grooves created, this application can also reduce tire wear and decrease the chances of the surface chipping over time. Innovative Technical Solutions, Inc. (ITSI) of Walnut Creek, California was chosen as the general contractor for the job. The original contractor chosen for the grooving work contacted ISTI shortly before commencement of the work. They were unable to do the job. Representatives of ITSI searched for experienced and reliable contractors that specialized in grooving, grinding and sealing work, and could start work on relatively short notice. CSDA members Cardinal International

w w w.CSDA.ORG

Grooving and Grinding, LLC of Conshohocken, Pennsylvania and Alaska Concrete Sawing, Inc. of Anchorage, were chosen to complete the specified rehabilitation of Runway 14-32. Cardinal was responsible for the grinding and grooving tasks, while Alaska Concrete Sawing concentrated on joint cutting, sealing and striping. It was clear from initial investigations that grinding out the existing grooves was the only viable option. Some of the grooves had become shallow due to years of having the surface scratched during snow removal. There were no other options to remove and replace the existing sealant either, as this too had been damaged by the shoveling and scraping of the runway surface. The abrasive but accurate nature of diamond tools was perfect to grind out the existing grooves, and Cardinal had the ideal equipment to complete the job.

CASES

The project was to be completed in four phases. Each phase was to be completed with only a seven-day buffer between the end of one phase and the commencement of the next. In each phase, the old grooves had to be ground out to the satisfaction of the engineer before new grooves could be cut into the runway. Then the old sealant was removed and the joints cleaned, so that new sealant could be installed. The 14,530 feet of grinding and grooving work was broken down to four phases measuring 2,500, 4,750, 4,750 and 2,500 linear feet. Durations were determined by the general contractor and were seven, 14, 14 and seven days respectively. The average depth of the grooves to be ground out was 0.25 inches. Cardinal used two PC5000B grinding machines manufactured by CSDA member Diamond Products to remove the existing grooved

surface. These machines utilize around 240 diamond blades to create a 4-foot-wide pass while cutting. To create the new grooved surface on Runway 14-32, the contractor used a 700-horsepower Safe-T-GrooverÂŽ, manufactured by Cardinal. Grooving was performed perpendicular to the centerline of the runway. Mounted with 76 blades, the machine cut 20-foot-wide sections in two passes. The machine was aligned on one side of the runway and created grooves across 75 feet of the surface, skipping six inches on each side of the centerline. The machine then stopped

1 4 | D ECEMBER .11

and returned back to the starting point to make another pass, making sure to stay six inches from the transverse joints. This process was repeated for the entire 14,530 feet of the runway. The grooves created were an average of 0.25 inches deep, 0.25 inches wide and were spaced 1.5 inch apart. Water tankers continuously fed the machine to keep the blades cool and slurry was collected by an on-board vacuum system. It was then returned to a water tanker for disposal at a designated dump site. During the work, striping had to be applied on both a temporary and permanent basis prior to the opening of the runway each

day. Both sealing and striping tasks were performed by Alaska Concrete Sawing (ACS). The team from this contractor was given the task of completing five monthâ&#x20AC;&#x2122;s worth of work in three, replacing a deteriorating neoprene seal and resizing existing concrete joints on the runway. The job required the sealing of 98,000 linear feet of joints. The existing neoprene seal was to be removed by hand, but ACS encountered a problem when it was found that the keel joint contained a solid material that had been applied with heat. This section of the seal was unable to be removed by hand or by cutting

methods, so the contractor engineered a tool attached to a fork lift to plow the material to the surface. Once the seal was removed, the joints were resized to 0.75-inches wide by 2 inches deep using an E-Z Rider joint saw from Diamond Products. The saw has an up-cut motion to clear debris from the joint while cutting. ACS also repaired 200 locations on the runway where spalling of the concrete had occurred. Sizes and depths of spalled areas ranged from 5 to 12 inches in width and length and 4 to 14 inches in depth. Once the seal removal and spall repairs were complete, the new neoprene seal could be installed. The contractor applied 1,000 feet of a Dow 888 silicone sealant per each eight-hour shift, finishing the work two weeks ahead of schedule. “Without the teamwork shown by Cardinal and ourselves, and the strong commitment of our six-man crew, this project would not have been completed on time,” said Matt Chambers, project manager for Alaska Concrete Sawing, Inc. Before any of the grinding work could begin, however, Cardinal had to get all of the required equipment to Alaska on short notice. Grooving and grinding machines were transported through Canada as quickly as possible to get operators working and keep the project on schedule. Cardinal had to mobilize fast to meet rigid time constraints that could not be adjusted. Spare parts for equipment had to be flown in, so the contractor had to factor in lead times for deliveries. Lodging for company personnel also had to be secured on a very short notice and during the height of the tourist season. The work environment was also something with which the cutting teams had to contend. Some contractors wish there were more hours in a day, but when Cardinal and ACS worked on this job, its operators encountered 24-hour sunlight for days on end. This is because of the geographical location of the job and the time of year that the work was done. During the summer months, places so far north from the equator can experience days of continuous daylight. This had an effect on the circadian rhythm of the operators, who had never worked in this type of environment before. Working eight-hour shifts through the night in broad daylight was a shock to the system. Working on a U.S. Air Force base, the contractors also had set procedures for the start and end of each night shift. At the end of each day, the general contractor would contact the tower when the final scheduled

Benefits of Runway Grooving

Cleanup was completed about 30 minutes prior to the first scheduled flight of the day, so that the general contractor and the Air Force could conduct a final walk around inspection of the work area. This was to make sure there was no hazards or waste materials

left on the runway to interfere with aircraft take-offs and landings. The grooving and grinding totals for each phase equaled more than 120,000 square yards. If the grooves created were lined up end to end, they would stretch over 1,500 miles. In regard to the grinding, over 836 cubic yards of waste material was removed from the runway.

In May of this year, during the 2011 annual meeting of the International Association of Concrete Drillers and Sawers (IACDS), Phillip Zuzelo of Cardinal International Grooving and Grinding LLC, gave a presentation about the benefits of runway grooving and the utilization of trapezoidal-shaped grooves. Zuzelo explained how the method of concrete grinding is being used on airport runways to prevent aircraft from hydroplaning in wet conditions. The creation of grooves on a runway can reduce aircraft braking distances by providing channels for water to run off the concrete surface. This increases tire friction and therefore aids with the braking of the aircraft. Statistics showed that in wet conditions, a plane with totally worn tires on a grooved runway achieved better braking than one with new tires on an untreated runway. When traveling at 70 knots in 2.5 millimeters (1 inch) of standing water, a plane with worn tires had a frictional coefficient braking level around 40μ on a grooved surface. When a plane with new tires began braking on an untreated runway in the same test conditions, the frictional coefficient braking level was around 25μ. Further analysis showed that creating trapezoidal-shaped grooves in the concrete surface also reduced tire wear, reduced rubber build-up and decreased occurrences of chipping or closing compared with standard grooves.

Cardinal International Grinding and Grooving, LLC is based in Conshohocken, Pennsylvania. The company has been a CSDA member company since 2003 and has been in business since the 1950s. The company offers the concrete cutting services of grooving and grinding on an international scale. Alaska Concrete Sawing, Inc. has been a CSDA member company for 16 years and is based in Anchorage, Alaska. The company services the entire state of Alaska and has eight operators and five trucks. Alaska Concrete Sawing offers the services of flat sawing, core drilling, wall sawing, wire sawing, selective demolition, grooving and grinding, joint sealing and hydro demolition.

Alaska Concrete Sawing was responsible for the restriping of the runway after each shift.

The grinding and grooving sections of the work were completed almost one month ahead of the scheduled deadline. “Not only did we finish the project ahead of schedule, the U.S. Air Force was extremely happy with the end product,” said Philip Zuzelo, owner of Cardinal. “It is believed that they will be looking to award more projects of this type in the future, as the rehabilitation of the runway by grooving and grinding worked out to be much cheaper than some other resurfacing methods and caused less disruption.” This is a great example of how CSDA members can join forces and combine their services to complete high-profile jobs. The runway is back in full operation and the 354 FW continues its operations from Eielson Air Force Base on a safer and more efficient surface.

Dry Drilling with PCDs By Les Kuzmick and Mike Nelson

What is a PCD? Polycrystalline diamond (PCD) is the product of sophisticated highpressure, high-temperature technology, in which carefully selected synthetic diamond particles are sintered together in a powdered metal matrix. The random orientation of the diamond particles produces a high uniform hardness and resistance to abrasion in every direction. This polycrystalline diamond layer, which is very thin, is integrally bonded to the forward edge of a super tough tungsten carbide substrate, which provides strength and permits joining with other metals. The PCDs look like a tungsten carbide cutter tooth with a thin coating on the cutting edge, and are available in many different shapes and sizes.

2 0 | D ECEMBER .11

Consistency of manufacturing parameters is a major advantage of a PCD. The structural integrity of a PCD produces a much more aggressive cutting action than diamond-impregnated bits in a variety of applications, including dry drilling brick, block, stone and concrete. Applications PCDs have been widely used in many industries as a component for precise machining tools, and this technology has also been adapted to the sawing and drilling industry. Applications that previously could only be wet drilled can now be drilled dry with uniquely designed PCD core bits. Drilling dry provides cutting contractors with the opportunity to drill old

buildings, historical sites and other sensitive environments that require structural improvement. These types of locations cannot stand up to slurry migration, contamination and structural compromises that can result from wet drilling. Since the introduction of PCD technology to the sawing and drilling industry, numerous high profile deep drilling projects have been accomplished all over the world. Dry drilling with PCD technology opens up a significant service sector market by making these projects possible. If it were not for the use of PCD products and the applications of advanced cutting techniques, there is a very high probability that a number of projects may never have been undertaken. Diamond tools utilizing PCD technology can be expensive. However, these products can potentially produce cutting rates and segment life equal to, or greater than, wet cutting tools. Combine this with the fact that contractors now possess tools that will help them successfully complete a wider variety of jobs, some of which they would otherwise not have been able to complete, and it is clear that this can be a potentially very profitable investment. Techniques Dry drilling with PCD core bits must be undertaken with respect to a number of techniques and factors that influence the success or failure of the project. Drilling speed, debris removal and tool temperature are a few of the factors that have major impacts on performance and tool life. Drilling Speed Dry drilling requires a much slower rpm than conventional wet drilling. Since the cutting action of a PCD bit can produce much coarser debris, a slower rpm allows for debris to be cleared more efficiently. Also, a reduction in heat buildup from operating at a slower rpm allows for greater production and reduced wear rates. Recommended rpm Speeds: 1- to 1.875-inch core bit diameter = 100 to 500 rpm 2- to 6-inch core bit diameter = 50 to 200 rpm

Penetration Dry drilling requires moderate and steady pressure on the bit with reduced pressure through steel. PCD core bits are very aggressive cutters, even in material like steel that can dull diamond segments. The driller must be prepared to quickly back off feed rates when encountering steel. Periodically, drilling penetration should cease completely to help the bit to cool and allow debris to clear from the cut. When a drilling operation encounters very hard, non-abrasive materials or fractured nonhomogenous debris conditions, the aggressive cutting action of PCD bits can cause chatter that slows the drilling process. Changing the PCD bit to a segmented core bit specially designed with heat-resistant silver solder, or laser-welded dry drilling segments, can help the penetration rate and reduce chatter through such conditions.

Cutting professionals are our only focus. Come to see us at WOC, Booth #C5921

Debris Removal and Cooling The removal of drilling debris and the cooling of the bit are critical to the success of any dry drilling job. If debris is not properly removed or the bit is not sufficiently cooled, the wear rate of the bit will greatly increase and the bit will jam in the hole or burn up. To ensure proper debris removal and sufficient bit cooling, a combination of compressed air Safety and First Aid going in the hole and a dry vacuum to clear Guidelines and Resources debris coming out is required.

Pillar of Society

Concrete Cutter Removes Bridge Section

The pillar was 55 feet long, 5 feet tall and 24 inches thick.

n April and May of 2010, the Dahlia Street Bridge in Adams County, Colorado, was replaced, leaving a large standalone concrete pillar from the old bridge in place. The bridge

crosses the Oâ&#x20AC;&#x2122;Brien Canal, a waterway constructed to provide water to Barr Reservoir and supply the surrounding residential areas. However, by November 2010 the pillar that was left behind was causing debris to build up under the bridge and block the flow of water through the canal. This pillar needed to be removed as soon as possible with only a short amount of time available to do it. 2 4 | D ECEMBER .11

Heavy equipment, like this backhoe, was lowered into the work area by crane.

Removing and hauling away the 55-foot-long, 5-foot-tall and 24-inch-thick concrete bridge pillar was no easy task, especially as the pillar now had the new Dahlia Street Bridge positioned just above it. Because of the location of the pillar—in the middle of a canal underneath a bridge—it would take around 20 men and multiple jackhammers over an extensive period of time to demolish the pillar. Not only would this method have required a large amount of manpower and extensive time, but the vibrations from jackhammering may have compromised the floor of the canal. A more subtle and precise removal method was needed, so concrete cutting with diamond tools was considered to be the best option. Several demolition contractors submitted bids to the general contractor for the project. One of these bids was from CSDA member DeAndrea Coring & Sawing, Inc. “Our bid was the lowest, but the general contractor did not believe we could get the job done within the budget we submitted,” says Paul DeAndrea, company owner. A 5-foot vertical cut was made to split the pillar into two 42,000-pound sections.

“Fortunately, representatives from Adams County were impressed by the presentation of our bid and had heard of our reputation. They placed their faith in our ability to complete the job as stated, on time and within budget, and gave us the opportunity to work for them directly.” Access to the work area was limited to a two-day period. This was because the O’Brien Canal had to be shut down to allow DeAndrea to set up a work area on the canal bed to perform the cutting. The canal feeds Barr Reservoir just a few miles away and the reservoir requires a regular flow of water to keep it sufficiently filled. If the cutting contractor did not meet the deadline set, the

reservoir would not be adequately filled. The team from DeAndrea had a plan to separate the 55-foot-long concrete pillar into two pieces and create a system to pull the two concrete blocks from underneath the bridge for crane access. This would allow the demolition of the cut sections to take place outside of the canal and ensure that the canal would be reopened on time. Once the section of the canal running under the Dahlia Street Bridge had been drained, all tools and equipment were lowered to the canal floor by crane. The first cutting task for DeAndrea Coring & Sawing was to flush cut along the bottom of the 55-footlong concrete pillar to separate the pillar

K2Diamond-EDTAd2_Layout 1 10/7/11 11:28 AM Page 1 from the existing slab. Two cuts were made using a Longyear 360 hydraulic saw. Each cut covered the length of the pillar and was made 12 inches deep to penetrate the entire 24-inch thickness of the concrete. It took one operator and helper eight hours to complete each cut. The Longyear saw was then track mounted to make a 5-foot-long, 24-inch-deep vertical cut down the middle of the 55-foot-long pillar to separate it into two 42,000-pound pieces. This cut took one hour to complete, before a four-speed Diamond Tech core drill was employed to create eight 24-inch-deep holes measuring 3.5 inches in diameter. These holes would allow chains to be pulled through the cut concrete sections so that the pieces could be attached to a backhoe and crane for removal. Now that cuts had been made to separate the pillar from the slab and split it in two, the contractor had to remove the cut pieces from under the bridge to be craned out from the work area. To begin this process, DeAndrea used a chain saw from ICS to make a 12-inch by 12-inch notch at the bottom ends of each 24-inch-thick cut piece. The contractor then placed specialized heavyweight bottle jacks in each of the four notches to raise the cut concrete sections and insert 4-foot-long, 3.5-inch-diameter steel rods between the pieces and the slab. This would allow the two pieces to be rolled out from under the bridge when ready for removal. A backhoe was then craned down to the canal floor and connected to the first piece scheduled for removal. By using the backhoe to pull, the 42,000-pound concrete piece was rolled out from under the bridge onto a 1-inch-thick trench shoring steel plate. This helped to maintain the integrity of the slab on the canal floor. After the first piece was rolled out, the crane was utilized to lift the first piece out from the canal to allow demolition to commence. This process was then repeated for the other cut section. Each section took approximately five minutes to roll out from under the bridge before being removed by crane. To maintain control of the cut sections during removal, the cutting contractor had to choose the location of the core holes wisely. By doing so, weight was distributed evenly and restricted uncontrolled movement of the pieces during removal. A cleanup operation was completed before the work area was deemed safe for the canal to flow under the Dahlia Bridge once more. The two 42,000-pound cut sections were placed a safe distance from the canal for final

The project was completed on time and within budget, as required. “I was very satisfied with the work, because this was a non-traditional cutting project that my company had never attempted throughout my 29 years in the industry. The overall result of the project turned out better than expected,” concluded DeAndrea. DeAndrea Coring & Sawing, Inc. used a 360 hydraulic saw from Longyear to perform the flush cuts and the vertical cut to split the pillar, an ICS chain saw to make the notches for the bottle jacks and a four-speed core drill from Diamond Tech to create the rigging holes. A crane and backhoe were used to pull and lift the cut concrete sections, while four bottle jacks, a 1-inch-thick trench steel plate and eight cold steel rolls were used to roll out the sections from under the bridge. In total, the contractor performed 108 feet of flush cutting to depths of 12 inches, 5 feet of vertical hand sawing 24 inches deep, chain sawed four 12-inch-long, 12-inch-tall and

24-inch-thick notches in the pillar wall and core drilled eight 3.5-inch-diameter holes through the 24-inch-thick concrete. DeAndrea removed and hauled 275 square feet of 24-inch-thick concrete weighing 84,000 pounds. Most of the cutting work was completed after the first day of the work. The contractor returned on the second day to finish all cuts and remove the pillar before flow to the canal was restored. The representatives of Adams County were repaid for their faith in the cutting contractor. The county believed that DeAndrea could complete the job as described, on time and within budget, strengthening the CSDA member’s reputation. Positive results like this prove that CSDA contractors are true to their word and are the real pillars of society.

Exercise Linked to Reduced Worker Productivity By Erin Oâ&#x20AC;&#x2122;Brien

hile this may be the excuse some workers are looking for to spend less time working out, this title is

slightly misleading. A recent study found that

while exercise may help some workers feel less stressed, it could also make them less productive. The workers studied were also found to have very high levels of job stress and exercised frequently to try and cope with the stress. However, it was found that workers who have high job stress and also a high level of physical activity were significantly less productive. The underlying cause of reduced productivity is not the high level of physical activity

3 0 | D ECEMBER .11

however; the study found that these workers were less productive due to their high levels of job stress. Workers who are stressed on the job also tend to be less healthy, which can lead to reduced productivity. The same study found that workers with higher bodymass index (BMI) worked less, whether due to reduced productivity or time off due to illness, regardless of any other factors. So in short, while healthy workers can be happy and productive workers, stressed and unhappy workers tend to be unhealthy and less productive. The important thing for both workers and employers to remember is that workers who are stressed will be less productive. Job stress

is defined as the harmful physical and emotional responses that occur when the requirements of the job do not match the capabilities, resources or needs of the worker. Job stress can lead to poor health or injury. Various studies about job stress have found that one-fourth of employees view their jobs as the number one stressor in their lives, and that problems at work are more strongly associated with health complaints than financial or family problems. Each worker will cope with job stress differently. Some adapt to their jobs and are able to handle the stress without an adverse effect on their health or productivity, while others lack natural coping mechanisms and will allow the job stress to negatively affect their performance and health. What may be stressful to one person may not be a problem for someone else. Scientific evidence suggests that certain working conditions are stressful to most people. This evidence argues for a greater emphasis on working conditions as the key source of job stress and for a job redesign as the primary prevention strategy. Recognizing conditions that may lead to job stress is important in prevention. Some of these conditions are: • The design of tasks—heavy workload, infrequent rest breaks and long work hours •

Management style—poor communication in the organization, lack of familyfriendly policies

•

Interpersonal relationships—poor social environment and lack of support from coworkers or supervisors

•

Work roles—conflicting or uncertain job expectations, too much responsibility

•

Career concerns—job insecurity, lack of opportunity for growth or advancement

•

Environmental conditions—unpleasant or dangerous physical conditions

If workers are experiencing some or all of these conditions, they may start to exhibit signs of job stress. These include: • Musculoskeletal disorders—especially back and upper extremity conditions •

Psychological disorders—such as depression and burnout

•

Cardiovascular disease—high blood pressure is an early warning sign

Prevention of job stress is the key to productive and healthy workers. Individual and situational factors that can help to reduce the

C O RE H E A LT H effects of stressful working conditions include: • Balance between work and family or personal life •

A support network of friends and coworkers

•

A relaxed and positive outlook

The best way to prevent job stress or reduce the incidence of worker job stress is to promote an environment of recognition, opportunity and compassion for workers. A healthy organization will have characteristics associated with low-stress work and high levels of productivity. Examples of these characteristics include: • Recognition of employees for good work performance •

Opportunities for career development

•

An organizational culture that values the individual worker

•

Management actions that are consistent with organizational values

By identifying problems, either in the individual worker’s job or throughout the organization, employers and workers can both take steps to reduce job stress. Once problems are identified, interventions need to be designed and implemented and, finally, the interventions should be evaluated for effectiveness. The benefits of a low-stress job environment will pay off in the long run for the employer, but even more so for the worker.

The Business of Business

Diversifying Your Business— Why GPR Should be on Your Radar By Matt Dragon

oncrete sawing and drilling contractors have found that one way to grow in today’s economy is to diversify

their service offerings to clients and offer a one-stop-shop approach. The more services provided, the more revenue contractors can generate. It can be a much easier sell to potential customers when a range of services can be offered from the same concrete cutting contractor. Adding and diversifying services also improves efficiencies in mobilization, billing and employee utilization. This strategy works best when the additional service couples closely with a contractor’s expertise and experience. The aim is not to deviate too far from the core competencies on which the business has been built, but to enhance service offerings and add value. The customer gains valueadded savings by using one subcontractor to perform a range of services, and the contractor makes more money from the job. Of course, the addition and diversification of services also means acquiring equipment and training personnel. Before a decision is made to add a new service, business owners should consider the following: • What would be the capital investment? •

Would the company’s geographical market accept and support these services?

•

What sort of training would be required?

•

Will adding the service impact the company’s on-site liabilities?

•

What is the payoff?

A good example of diversification in the concrete sawing and drilling industry is the addition of concrete scanning services. Scanning concrete to locate structural targets as well as utilities has become an excepted practice in today’s cutting and coring industry to identify potential hazards at cutting locations. Several CSDA member companies have added this service—some have a separate division for scanning, while some members are standalone scanning companies.

3 4 | D ECEMBER .11

FIGURE 1

FIGURE 2

Concrete scanning equipment utilizes Ground Penetrating Radar (GPR) to image and locate targets in concrete. This allows a contractor to immediately mark out a cutting location prior to performing cutting or coring work. The service is typically written into a specification as “X-RAY” or equal technology to locate critical targets in the concrete, such as:

•

Steel reinforcement (rebar or posttension cables)

•

Embedded plumbing like water feed or drain lines

•

Electrical conduits

•

Bottom of the slab

How GPR Works GPR works by sending high frequency radio waves into material like concrete and measuring the travel time for the returning reflection (Figure 1). Reflections are caused when the GPR wave encounters a material with a different dielectric constant; or to put it simply, a change in material. Rebar, posttension cables, conduits, the bottom of slab and voids all generate reflections that are detected and shown on the GPR display. Scanning data is collected in two ways: line scan and grid scan. Line scanning is performed by moving a GPR antenna across the surface of concrete perpendicular to targets in the slab. This results in a cross-sectional view of the slab with targets imaged as hyperbolic peaks, as seen in Figure 2. Each peak represents the end of a structural steel object. In the case of Figure 2, there are two rebar mats depicted as well as the bottom of the slab, denoted by the green line. A grid scan is performed by systematically collecting several line scans of data in the X and Y directions of a specified area. A grid scan utilizes the line scan data collected to generate a top-down three-dimensional image that more closely resembles a picture than the traditional line scan. This top-down view can be analyzed in the field for location of targets as they appear in layers of the scan. Figure 3 depicts a wire mesh as it appears in a layer within the scan. Other targets like PVC conduits could be imaged on a completely different layer. Grid

Contractors adding this service as a new division should set up dedicated sections or pages to an existing website or consider creating a separate one altogether. The commercial approach represents a deeper commitment to the business. This may also mean the assignment of a dedicated crew to not only perform the work but also to quote and sell projects.

scans can remove confusion when scanning a complicated scan location. Capital Investment Concrete scanning equipment can range in cost from $12,500 to $25,000. There are several manufacturers of this type of equipment, each offering its own range of systems. These systems range from handheld GPR scanning equipment to more commercial GPR systems that accommodate a variety of antennas for different concrete depths and desired image resolutions. Going to Market Whether a contractor is looking to make this additional service available to its complete customer base or just a select few, marketing the service can be challenging. Phone calls and a mailing campaign may suffice, but often the best marketing tool is word of mouth. Employees should be encouraged to spread the word on job sites and arrange demonstrations at client office locations. Dispatchers can ask customers if they would like the project scanned before sending a sawing and drilling crew to the site. If scanning is to be the primary function of a new division or business, additional marketing steps can be taken. The creation of a website is almost a necessity in today’s tech-

Training Concrete scanning is a service that not only requires structured training but also an appropriate employee skill set. The best sawing or drilling operators may not necessarily make the best scanners. Employees should have at least a basic understanding of steel reinforcement in concrete as well as other targets like conduits and drain lines. Besides these basic understandings, he or she needs to understand thoroughly how to use GPR equipment. It is important for potential scanning employees to understand how to get the best results from scanning equipment and in what situations. Similarly, they should know when the use of GPR equipment will be problematic and how certain environments will affect performance. For example, GPR will not perform well in green concrete. This information can be referenced in detail by reviewing the CSDA Best Practice (CSDA-BP-007) Ground Penetrating Radar for Concrete Scanning. Training should be an important item to cover when considering entering the GPR scanning market. On-Site Liability Concrete sawing and drilling contractors should be familiar with the requirement of insurance to operate. Liability is addressed differently by each individual organization. Some cutting and coring contractors will set up a separate company for GPR scanning services, while others will include the service with their current offerings. GPR may be the best technology for locating targets in concrete, but nothing is always 100% accurate. Operator error is always a factor and there are also instances where GPR

may not produce an image for a target. It is important that contractors know and respect the limitations of GPR, and set the expectations of the clients accordingly. It is also important for contractors to protect themselves and manage risk through the purchasing of robust, quality equipment and through the education of operators. Liability statements for onsite work are a part of that protection. Section 6 of the CSDA-BP-007 provides more information about liability for GPR scanning. Payoff As with other equipment investments, anticipated revenue from scanning is directly connected to utilization in the field and market forces impacting price per hour. Therefore, anticipated revenue will be a “fill in the blank” exercise for any managers or owners considering the addition of GPR to their businesses. Contractors should consider the following: • Does the business currently sub-contract scanning, and how much is being left on the table? •

Are projects being lost to the competition because other contractors scan and your business does not?

•

Out of the many cutting and coring projects completed year after year, how many required scanning? If the answer is some or none, regard the projects that were not scanned as potential customers that could help grow a scanning service in the future.

The addition of GPR may be the most suitable solution for a business to diversify. Each regional market and business skill set is different, so this should be taken into consideration when making a decision on GPR, but if there is a gap in the market and your sawing and drilling business is able to add a service like GPR, then there is potential for business growth and increased revenue.

More OSHA/CSDA Alliance Best Practice Documents Released The Alliance released two new Best Practice documents in August and September on the subjects of distracted driving and hearing conservation. The total of OSHA/CSDA safety documents is now at nine. The risk of a vehicular crash increases when sawing and drilling employees engage in distracted driving. This includes any activity that has the potential to distract employees from their primary task of driving or increase the risk of crashing and decrease the opportunity to avoid the accident altogether. Noise exposure is widely recognized as a commonplace hazard in sawing and drilling operations. The big issue is that on any given day, the noise level will vary from one jobsite to another. These two new Best Practices, CSDA-OBP-1007 – Distracted Driving and CSDA-OBP-1008 – Hearing Conservation, provide guidelines and tips for employers and employees to drive safely and to protect themselves from damage or loss of hearing. To date, the Alliance has released eight Best Practices and a Toolbox Safety Talk. Four of these Best Practice documents are also available in Spanish.

Creating the Link

C O N C R E T E

Airport Link is a new 6.7-kilometer (4.2-mile) toll road and tunnel under construction in Queensland, Australia. It is the country’s largest privately-funded transport infrastructure project to date, and is expected to open to the public in the middle of 2012. Part of the $4.8-billion AUD ($4.5-billion USD) project required the core drilling and sawing of concrete structures to expose tension piles and facilitate the inclusion of reinforcing slabs. Some of the core holes created needed to be as big as 1,000 millimeters (39.4 inches) in diameter and be 1,200 millimeters (47.2 inches) deep. Heavy reinforcement in the concrete meant the contractor had to use a specialized lubricant to keep the project on track.

Core Drilling Helps to Form New Airport Link Road

w w w.CSDA.ORG

hen complete, the new Airport Link toll road will connect the city’s central business district to Brisbane Airport, the Australia TradeCoast industrial district and the rapidly-growing northern suburbs. It will provide several entry and exit points to alleviate traffic on some of the city’s other commuter routes. As part of the project, two massive concrete boxes, approximately 65 meters long (213.3 feet) and 12.5 meters tall (41 feet) have been placed under Queensland’s busiest railway line without disruption to train passengers. These jacking boxes formed part of a tunneling operation under one of the

railway line’s embankments. Hydraulic jacks and steel strands pushed and pulled the boxes under the embankment while excavators inside the boxes dug out the earth to keep the boxes slowly moving forward into position. Thiess of South Bank, Queensland entered into a joint venture with John Holland of Brisbane for the Airport Link project, forming the Thiess John Holland Joint Venture. The joint venture needed to enlist a specialist concrete cutter that had the experience and equipment to handle a range of tasks along the link, and chose CSDA member Fast Cut Qld Pty Ltd of Brisbane to complete the work. The most significant portion of the contractor’s work was to drill 52 large holes to 1,000 millimeters (39.4 inches) in diameter

and 1,200 millimeters (47.2 inches) deep through 80-megapascals (11,603 psi) concrete and 40-millimeter-thick (1.6-inch) reinforcing bars. These core holes were required to expose tension piles for concrete slab tie down. Another task included flat sawing through an 800-millimeter-thick (31.5-inch) slab to expose the earth below and creating around 9,500 small-diameter core holes to provide keying for a reinforcing slab. This slab was to be installed to prevent side slip of the tunnel section as employees of the joint venture

moved the slab into place. In addition, the ends of jacking boxes, measuring 1.5 meters wide (5 feet) by 17 meters tall (55.8 feet), were to be cut and removed. Core drilling with diamond tools was the most efficent way to access the tension piles. As the project was to run in 24-hour shifts and ran through a suburban area, noise restrictions were put in place to protect workers and nearby residents from excessive noise levels. Using core drilling techniques with diamond tools produces less noise than traditional

demolition methods. In additon, this technique made sure the contractor stayed within critical dimensional tolerences, as deviations from these tolerances would have led to extra restoration work after the completion of the project. The non-destructive nature of core drilling also minimized vibrations that could have compromised the structural integrity of surrouding buildings and structures. â&#x20AC;&#x153;We had considered all the options available to us, like plunge sawing, but core drilling was the ideal choice,â&#x20AC;? says Rex Scoles

of Fast Cut Qld Pty Ltd. “This technique met all of the criteria set by the joint venture, so we began looking for a company that could supply us with the equipment we needed.” Scoles contacted a representative from Traxx Construction Products to procure the necessary core bits and rigs. Before the team from Fast Cut could commence cutting work on the Airport Link site, a full job safety analysis and work method had to be completed and submitted to the Thiess John Holland Joint Venture. Upon approval, the contractor set up and began creating a test hole. As the operator drilled, it was discovered that the steel reinforcement in the concrete was greater than the client initially thought. In consideration of this discovery, modifications to the work method were made. Each hole had a top layer of 200-millimeter-thick (7.9-inch) steel with only 50 millimeters (2 inches) of cover. The first layer consisted of 27 bars each measuring 40 millimeters (1.5 inches) in diameter followed by various numbers of 40-millimeter-diameter (1.5-inch) bars at 200-millimeter (7.9-inch) spacing down the length of the core. Finally, there was a bottom layer of another 27 bars measuring 40 millimeters (1.5 inches) in diameter. This meant that initial projections for completion of the drilling work were not achievable, so a second drill rig was brought onto the site. Initial targets for the job were to complete one to two holes every 24 hours, so the addition of a second rig helped maintain this pace. However, some holes were taking up to 36 hours to complete, so Fast Cut had to come up with a new plan. A manufacturer representative was brought on site to review cutting progress and suggested the use of a diamond tooling lubricant. A small amount of Traxx CFQ lubricant was mixed with the water supply, between 2% and 4% of the total quantity of the mixture, to extend the life of the diamond segments on the core bits and increase drilling speed. Operators found that after applying the lubricant, drilling time was reduced from 36 to 12 hours per hole. In addition, the life of the diamond segments was increased an average of 30% while drilling speed was greatly increased—an average of 200%. The load on the power pack and hydraulic drill motor was also reduced by 40%, saving fuel, wear and tear and CO2 emissions. In addition, water consumption was reduced, as less time was spent drilling. The contractor then went on to complete approximately 10,000 meters (32,808 feet) of

flat sawing on reinforced concrete slabs to a depth of 800 millimeters (31.5 inches). This was to cut through the slab and allow the general contractor access to the soil below. The tails of the jacking boxes were then to be removed by wire saw. Fast Cut wall and wire sawed four bottom sections and two top sections, each measuring 1.5 meters wide (5 feet) by 17 meters tall (55.8 feet), before the cut sections were removed by crane. Pre-start meetings were held before each shift change to discuss activities and address any safety concerns. Working

around several other contractors, supervisors from Fast Cut had to make sure that their operators were aware of restrictions in the work area. The contractor was working to strict time constraints and timing had to be closely monitored. Due to the size of the 1,000-millimeter-diameter (39.4-inch) by 1,400-millimeter-tall (55-inch) core bits and the drilling rigs, the contractor had to ensure that the work area was free from any incumbents and strictly followed all health and safety standards set for the project. The general contractor placed safety barricades around

the work area so no vehicles or unauthorized personnel could access the area. To run the two drill rigs on site, Fast Cut modified its own diesel-powered hydraulic power pack by setting up two hydraulic circuits. The remainder of the tools and equipment needed to complete the job, including drill rigs, core barrels, core bits and diamond tool lubricant, were either manufactured or supplied by Traxx Construction Products. Representatives from the manufacturer were also on hand to provide on-site service support while the cutting work was done. In total, 52 holes were drilled on the Airport Link toll road, which produced concrete cores each measuring 1,000 millimeters (39.4 inches) in diameter, 1,200 millimeters (47.2 inches) tall and weighing over 3 metric tons. As a result of cutting these cores, 156 metric tons of concrete was cut and removed by Fast Cut. In addition, the contractor performed 10,000 meters (32,808 feet) of slab sawing, drilled 9,700 small-diameter holes in a reinforced slab and wire sawed six jacking box tail sections measuring 1.5 meters wide (5 feet) by 17 meters tall (55.8 feet).

The job completed on time in the alloted two months, having three crews of operators work alternating 12-hour shifts on a 24 hours per day, seven days per week schedule. The job remained on budget throughout, and as a result of Fast Cut’s performance, the joint venture has awarded the contractor more wall, floor and wire sawing work on the project. “I’m really satisifed with our work,” said Scoles. “The project was completed on time without any major issues, thanks to the continuous commitment of my operators and the help provided by my suppliers. I have skilled, trained operators in every discipline who have been able to show the joint venture their experience on several parts of the Airport Link project,” he concluded. The Airport Link toll road is set to open in June 2012 with the aim of improving Brisbane’s road system. The work completed by this CSDA member has helped to keep the whole project on schedule and shown general contractors the benefits of cutting and coring with diamond tools. The contractor has helped create the Airport Link while forming important links of its own with general contractors.

Basement Egress Window Systems By Kevin Warnecke and Tom Stowell

Installation Suitable tools for the creation of an egress window opening include a wall saw, diamond chain saw, circular hand saw or ring saw. A centerline must be marked on the wall above the window. A hole must be dug so it is centered across the window opening. The hole should be at least 4 feet wider, 1 foot deeper and 1 foot greater in projection than the area of wall being cut.

your concrete cutting business is in an area where residential basements are predominant, then you have an excellent opportunity to capitalize on a sawing application involving egress window system installations at residential dwellings. The term “egress” simply means a direct method of leaving a building. An egress window code is a legal requirement, intended to ensure a person can escape a building through a window in an emergency. Most codes also require egress windows to be large enough for a fully outfitted firefighter to enter through them. In general, the egress window code requires installation of an egress window to any habitable space in a basement area. If there are individual bedrooms added to a basement dwelling, then a separate egress window is required for each one. Most communities in the United States and Canada have based building codes on the International Residential Codes (IRC) created by the International Code Council, a membership organization that promotes building safety and fire prevention. These codes were developed with input from both organization members and the construction industry. The IRC include specifications for egress window sizes and locations, which vary slightly depending on the layout of the building. It is advised to check with your local code authority to see if it has authored its own rules or adopted the standards of the International Code Council. A typical basement egress window system consists of an egress style window, a window well and a window well cover. The installation of an egress window system requires an enlargement of an existing window or the addition of a new window. This can be accomplished by sawing into the existing basement block or concrete wall. The windows must have a minimum net clear opening of 20 inches wide, 24 inches high and have a minimum net clear (window) opening of 5.7 square feet. They must be installed so that the sill height to the finished interior floor measures no greater than 44 inches to meet the IRC-2006 code requirement. Common styles of egress windows have either a horizontal sliding window sash or casement type crank-out or crank-in window sash, depending on customer preference.

Preparation The preparation for the installation of an egress window system is similar to the preparation of any concrete sawing job. The contractor must first communicate with the home owner and confirm the location of all utility services before digging. Other obstacles that would interfere with digging and sawing, such as aerial power lines, aerial phone lines, roof overhang, down spouts, sprinkler systems, trees, branches, roots and interior restrictions, must also be reviewed and considered. In addition, the width and height of the window and the wall thickness and type, whether it is block or poured concrete, must be confirmed. 5 0 | D ECEMBER .11

Next, the type of installation must be determined. There are two types of installation; framed and non-framed. Framed installations can be used for both block and poured concrete walls. Non-framed installations can only be used for poured concrete walls. To determine the opening size for framed installations in block and poured concrete walls, measure the exterior of the window frame and add 3.5 inches to the width and height measurements. This allows 1.5 inches for lumber framing and 0.25 inches for shimming and sealant on each side. For non-framed installations, measure the exterior of the window frame and add 0.5 inches to the width and height measurements. This allows 0.25 inches for shimming and sealant. Prior to cutting the basement wall opening, you should determine if a lintel or a header is required as a load bearing building component. Basic lintels can be fabricated from an angle iron extending 6 to 8 inches past the opening size at each end. A header can be made from a steel tube with steel plates welded to each end that extend down to set on the sill plate. Since load bearing components are unique for every situation, you should contact a structural engineer for accuracy. To mark up the cutting area, draw a chalk line on the wall using the above dimensions, then spray the chalk line using clear marking paint to protect it from washing away during the cutting process. The measurement from the sill to the finished interior floor should be double-checked to ensure it does not exceed 44 inches. Making two or more horizontal cuts in the concrete area is advised, as this divides up and reduces the weight of the concrete for removal. Next, a hole should be augured at least 12 inches deep and a drain tile should be inserted at the bottom of the hole. For best results, the drain tile should be tied into the building’s lateral foundation drainage system, if available, using a “T” connector. The drainage system typically runs alongside the building’s footing.

Egress (Basement) International Building Code, 2006 The following code applies to the requirement of egress window systems:

Chapter 10 Means of Egress Section 1009 Emergency Escape and Rescue 1009.1 General. In addition to the means of egress required by this chapter, provisions shall be made for emergency escape and rescue. Basements shall have at least one exterior emergency escape and rescue opening in accordance with this section. Such openings shall open directly into a public street, public alley, yard or court.

The excess drain tile should be left above the ground to be trimmed later. Fill the bottom of the excavated hole with at least 8 inches of pea gravel to 3.5 inches below the wall opening. Level the gravel and trim the corrugated hose just above the gravel base. Cut along the chalk lines using a wet cutting concrete saw, penetrating all the way through the wall. Ensure the corners are square cut to minimize water leaks and improve the fit and finished appearance. Plumb, square and straight cuts will ensure a high quality window installation.

1009.2 Minimum size. Emergency escape and rescue opening shall have a minimum net clear opening of 5.7 square feet. 1009.2.1 Minimum dimensions. The minimum net clear opening height shall be 24 inches. The minimum net clear opening width dimension shall be 20 inches. 1009.3 Maximum height from floor. Emergency escape and rescue opening shall have the bottom of the clear opening not greater than 44 inches measured from the floor. 1009.4 Operational constraints. Emergency escape and rescue openings shall be operation from the inside of the room without the set of keys or tools. Bars, grilles, grates, or similar devices are permitted to be place over emergency escape and rescue openings provided the minimum net clear opening size complies with of requirement of this code which will be discussed later. 1009.5 Window Wells. An emergency and rescue opening with the finished sill height below the adjacent ground level shall be provided with a window well in accordance to the below.

A wood frame is required on a block concrete wall installation. On a poured concrete wall, a wood frame may or may not be used depending on preference. In order to build the frame, measure the wall thickness and rip lumber to the desired width using a table saw. Lumber for the sill and head should be cut to match the lower and upper dimensions of the sawed opening. Lumber for the side jambs should be measured from the head to the sill. The jambs should fit snug between the head and sill lumber. Remove loose lumber from the opening and apply sealant all the way around the inside of the concrete or block opening to ensure a watertight joint when window framework is installed. Install the window framework by fastening into the concrete wall with self-tapping concrete screws. For a block wall installation, fasten with rust resistant screws using a toe-nail method through the jambs into the head and sill boards at each corner. Sealant should be applied around the window frame wall joint on both exterior and interior sides.

w w w.CSDA.ORG

1009.5.1 Minimum size. The clear horizontal dimensions of the window well shall allow the emergency escape and rescue opening to be fully opened and provide a minimum accessible net clear opening of 9 square feet with a minimum dimension of 36 inches. 1009.5.2 Ladders or steps. Window wells with a vertical depth of more than 44 inches shall be equipped with an approved permanently affixed ladder or steps. Width: 12 inches min. Tread Depth / Clearance: 3 inches max. Riser: 18 inches max. Ladder / Steps may not encroach into well more than 6â&#x20AC;?. Ladder / Steps shall not obstruct the emergency escape and rescue opening function.

A helper should be positioned inside the basement to assist with window placement. Lower the window into the framed opening, inserting the bottom window edge first then tipping in the top. Shim the window from both the interior and exterior sides until it is level, square and flush with the exterior side of the basement wall. Take care not to damage the window with excessive shim pressure. If applicable, fasten the window unit frame to a wood frame using rust-resistant screws. Apply expanding foam to the window frame gap created by the shims. Allow the foam to cure for at least one hour before trimming excess away. Apply sealant around the window frame joint on both exterior and interior sides. The egress window well and cover can now be installed by anchoring to basement wall. Installation instructions will vary depending on the desired type of window well. In all instances, follow the manufacturerâ&#x20AC;&#x2122;s recommended procedures. Back-fill the window with leftover excavated dirt. The grade must slope away from the house and window well, and be at least 3 inches but

5 2 | D ECEMBER .11

no more than 12 inches below the top of the window well. The egress window system installation is now complete. Keep in mind these are general installation guidelines only. Adherences to local code authority and manufacturerâ&#x20AC;&#x2122;s installation guidelines are absolutely necessary for a watertight and approved installation. Whether the work is performed by a remodeling contractor who subcontracts out the sawing portion of the job, or the job is handled completely by the sawing contractor, the basement window egress system installation is an opportunity for concrete cutters to expand their businesses and increase their revenue streams.

Fall Hazard Liability for Host Employers By Mark A. Lies II and Timothy R. Gerlach

t is a fact of everyday business life that many employers will, from time to time, be required to engage outside contractors to perform a variety of services at the employer’s facility that the employer cannot perform with its own employees. Concrete cutting contractors are sometimes required to work in such areas as rooftops to perform renovation or demolition work, so it is important to know what liability is held not only by the contractor, but by the customer as well. Recently, OSHA has begun to expand the employer’s liability for OSHA compliance for employees of the outside contractor under its multi-employer workplace liability. A recent decision in the case of Secretary of Labor v. Ryder Transportation Services, OSHRC Docket No. 10-0551 (ALJ, February 28, 2011) should be noted, because it is one that most employers who own a fixed facility will face at some time if they engage an outside contractor to perform services. In this case, the focus was on the roof of the facility and the equipment— HVAC units—that was located there. This liability involved the hazard of outside contractor employees being exposed to injury because of fall hazards, either from the leading edge of the roof or from skylights or other openings in the roof. Ryder Facility The employer in this case, Ryder Transportation Services (Ryder), owned a facility that it used to rebuild automotive equipment for its vehicles. Since 2006, no Ryder employee had been on the roof and the roof was classified as a restricted area. Employees were forbidden to access the roof. There were a number of unguarded skylights on the roof. In 2009, Ryder requested an outside electrical contractor, M.C. Dean (Dean), to perform work at the facility to install exhaust fans near the ceiling on the inside of the building. After the fans were installed and failed to function, the Dean employees decided to access the roof to determine why the fans, which protruded through the roof, did not function. The Dean

employees utilized their own aerial lift to access the roof. A Dean journeyman electrician got out of the lift and walked to one of the exhaust fans. As the employee walked across the roof back to the aerial lift using a different route, he fell through a skylight to his death. Multi-Employer Workplace Liability OSHA cited Ryder for the exposure of the Dean employee to the unguarded skylight. Ryder could not be cited for the exposure of any of its own employees who had not accessed the roof. Using its multi-employer workplace doctrine, OSHA cited Ryder as the “controlling employer” for failing to protect the Dean employee from the hazard. The Administrative Law Judge found that the multi-employer workplace doctrine did apply and that Ryder was the controlling employer. He vacated the citation on a finding that Ryder had “neither actual nor constructive knowledge that an employee would be exposed to unguarded skylights that were remote from his work area.” OSHA has taken an appeal of the decision, claiming that Ryder had such knowledge. Host Employer Liability This decision represents a further confirmation of the extent of liability for the host or controlling employer under the doctrine. Now, any employer who engages an

outside contractor to perform work on its roof is potentially liable if it does not confirm. Outside contractor employees must be protected from any fall hazards on the roof. This will require the host employer to insure that skylights are guarded, as well as the leading edge of the roof, or that the employees are utilizing some other form of fall protection while accessing the roof. Many host employers have no knowledge of the applicable regulations and are relying upon the outside contractor to have such awareness, as well as appropriate fall protection for their employees. It is also a certainty that this liability will eventually extend to outside contractors coming to the employer’s worksite to perform all manner of services, including electrical, plumbing, excavation or structural repairs and renovation. Recommendations In order for operators of concrete sawing and drilling equipment to be fully aware of fall hazards and remain safe when working at a host employer location, the following actions should be considered by the host employer: • The host employer should conduct a job hazard analysis of its facility— in this case the roof—to determine whether there are fall hazards such as unguarded skylights, roof exhaust vents or other roof equipment that could pose a fall hazard.

CSU-201110-ConcOpen 2-3 Ad_CSU-201110-ConcOpenings 2-3 Ad 10/14/11 11:24 AM Page 1

•

Once the job hazard analysis has been completed, the host employer should consider what type of fall protection is required and feasible for employees and outside contractors who may be accessing the roof, or equipment located on the roof.

•

After the feasible means of fall protection are identified, the host employer should develop a written procedure that incorporates these measures, sets out the process for authorized employees to access the roof, details under what circumstances such access is permissible and what type of fall protection will be required.

•

Host employers should conduct documented training for authorized employees who access the roof, monitor their compliance and discipline employees who are non-compliant. When using an outside contractor to perform work on the roof or equipment on the roof, a meeting should be held to provide the outside contractor with information on the presence and location of any fall hazards on the roof or equipment. The host employer should confirm and document that the outside contractor has been informed of these hazards and that the outside contractor has the means and methods to provide the necessary fall protection for its employees and that it will supervise, monitor and enforce compliance with its fall protection program.

If the host or controlling employer undertakes these actions, it will minimize its potential liability for fall hazards on the roof for its own employees and minimize the risk of injury for outside contractors, such as concrete sawers and drillers, who may require access to these areas.

Insurance CornER

Commercial General Liability Insurance— How to Read the Policy By Jared W. Heald, Esq.

f you retain nothing else from this article, please remember this: the CGL policy is a contract. When there is an issue regarding the coverage provided under the CGL policy, the interpretation of the CGL policy is governed by state law, and the court will use the same rules regarding contract interpretation as are employed in other contractual disputes to reach its determination. As state law governs the interpretation of the CGL policy, it should not surprise you to know that many states interpret the same standard policy language differently, sometimes with significant consequences. For example, the law in some states is that “occurrence” (a defined term under the policy) includes situations where the insured unintentionally performs defective work, while other states’ law is that defective work cannot constitute an “occurrence.” However, going into detail on such intricate topics is beyond the scope of this article; instead, this article is intended to focus your attention on the best advice for any contractual matter— before entering into a contract, you should read and understand it. Before purchasing your CGL insurance policy, and paying thousands of dollars or more in premiums, you should understand what you are receiving in return. Providing an explanation of the structure and working of the CGL policy will help with that task.

5 6 | D ECEMBER .11

The Framework of the CGL Policy Comprehension of the CGL policy begins with an understanding of its structure and form. The CGL policy is a complex document with numerous sections, many interrelated clauses and alternative provisions, the applicability of which hinge upon numerous variables and facts. To many, it appears drafted with the intent to create an indecipherable puzzle. Do not let this discourage you. When the CGL policy is broken down into its parts, and those parts are studied and reviewed, it becomes easier to understand and you will be able to take control of this issue. Please note, this article discusses the standard CGL policy, the ISO (Insurance Services Office, Inc.) occurrence based CGL policy form—the CG 00 01.

•

The CGL policy consists of five sections: Coverages

•

Who is an Insured?

•

Limits of Insurance

•

Commercial General Liability Conditions

•

Definitions

Coverages This section details what insurance, or protection, is provided under the CGL policy and is divided into four parts: • Coverage A—Bodily Injury and Property Damage Liability •

Coverage B—Personal and Advertising Injury Liability

•

Coverage C—Medical Payments

•

Supplementary Payments—Coverages A and B

Each of the three parts identifying a type of coverage, parts A through C, has itself two subparts: (1) Insuring Agreement, and (2) Exclusions. The Insuring Agreement gives a broad promise as to what protection is provided under the particular coverage part. For example, for Coverage A, the Insuring Agreement provides “We will pay those sums that the insured becomes legally obligated to pay as damages because of ‘bodily injury’ or ‘property damage’ to which this insurance applies.” It further provides “This insurance applies to ‘bodily injury’ and ‘property damage’ . . . caused by an ‘occurrence’ that takes place in the ‘coverage territory’ . . . [that] occurs during the policy period . . . .” This is the main coverage provided by the CGL policy, and it is often summed up as a protection against claims for injury to person or property caused by an accident. The second subpart, Exclusions, restricts and narrows the broad promise contained in the Insuring Agreement by removing certain types of damages from coverage. For example, Coverage A has 17 categories of exclusions limiting the type of “bodily injury” or “property damage” that is covered under Coverage A. For contractors, some of the more important exclusions to Coverage A include: the contractual liability exclusion; pollution exclusion; aircraft, auto or watercraft exclusion; mobile equipment exclusion; damage to property exclusion (eliminating certain types of ‘property damages’ from coverage) and damage to your work exclusion. It is also important to note that particular exclusions contain their own limiting exceptions, meaning that in some instances the exclusions do not apply to remove a damage from the broader coverage promise. For example, the damage to your work exclusion mentioned above has an exception that applies (meaning that insurance coverage could be available) if the damaged work, or the work out of which the damage arises, was performed by a subcontractor. Thus, when determining what coverage is provided by the CGL policy, the starting place is evaluating the broad promise contained within the Insuring Agreement as limited by the Exclusions. This evaluation process is generally the same for all coverage parts, A through C. Note, while broken out separately, the fourth part of this section (Supplementary Payments) does not actually provide a type of coverage but, instead, details additional payments which the insurance company is willing to make under Coverage A and

w w w.CSDA.ORG

Coverage B, provided particular conditions are satisfied. It adds an additional layer of protection to the CGL policy by expanding the costs which may be paid under the other coverages. Who Is An Insured? This section is an extensive and detailed definition/explanation as to what persons or entities are afforded coverage under the CGL policy, and is broken down into several parts and subparts. The various parts and subparts modify who qualifies as an insured based upon particular variables such as type of loss incurred and relationship to the person or entity designated in the CGL policy’s declarations as the insured. Please note, “insured” is not separately defined under the CGL policy, see the Definitions section below. Limits of Insurance This section explains the maximum amount of money the insurance company is obligated to pay under the different Coverages provided. The CGL policy may have multiple limits of insurance that may reduce the insurance company’s payment obligations in particular circumstances. The more common limits are the: General Aggregate Limit, ProductsCompleted Operations Aggregate Limit, Personal and Advertising Injury Limit and Each Occurrence Limit. Any limit of insurance applicable to the CGL policy should be clearly listed in the CGL policy’s declarations. If any limit is listed as zero, that means there is no coverage for that corresponding category. For example, sometimes CGL policies will have a zero dollar limit for its Products-Completed Operations Aggregate Limit, which effectively operates to exclude from coverage all claims resulting from completed operations. Commercial General Liability Conditions This section has multiple parts and generally outlines the practical operation of the policy. For contractors, it is comparable to the general conditions section of construction contracts—it details how the parties to the insurance contract, you and the insurance company, are to interact with one another. The topics covered are varied, ranging from what happens if the insured goes bankrupt to the insured’s duties to maintain records for premium audits. One of the more important parts of this section is Part 2, “Duties In the Event of Occurrence, Offense, Claim or Suit,” which details what an insured is required to do under particular circumstances (such as when and how to notify the insurance company

Before purchasing your CGL insurance policy, and paying thousands of dollars or more in premiums, you should understand what you are receiving in return.

if you have been sued) so as to be able to maintain coverage under the policy. In many states, failing to comply with this condition is a basis for the insurance company to deny an otherwise covered claim. Definitions This section contains the definitions for particular words used throughout the other sections of the CGL policy. When reviewing the previous four sections of the policy, you know a word is a defined term when it is contained within quotation marks. For example, in the above discussion “property damage”, “bodily injury” and “occurrence” were all contained within quotation marks, indicating the use of defined terms under the policy. Often the definition of a word will contain multiple parts, some of which may apply only under certain circumstances. Also, some definitions are broadly stated and then limited by further parts and subparts. When dealing with a defined term under the CGL policy, it is often best to revisit the definitions to refresh yourself of the meaning under the policy.

Modifications to the Standard Language Sometimes the standard language of the CGL policy does not work for your particular insurance needs. In such a case, the standard CGL policy can be modified and tailored to your needs through the use of endorsements. Endorsements are amendments to the insurance contract and change the CGL policy terms, sometimes significantly. Perhaps the most common endorsement for contractors is the additional insured endorsement, of which there are many varieties, used to add other persons (such as a general contractor or owner) as an insured under the insurance policy. Whenever reviewing your CGL policy, it is important to review any policy endorsements to see how the standard language has been modified. Putting it All Together With this working knowledge of the CGL policy, you should be able to begin exploration of the CGL policy. For analysis of any particular issue, the evaluation of the CGL policy requires determination of the following, which generally may be considered in any particular order: • Who is protected against the identified risk? •

Is the risk covered? Remember to review exclusions and exceptions.

•

Are there any policy limits that impact the available coverage?

•

What, if anything, needs to be done to preserve the protections afforded under the policy?

When conducting a review, remember that you must incorporate the definitions contained within the Definitions section and consult the information contained in the policy’s declarations. Do not forget to check for any endorsements. The CGL policy is a complex contractual agreement. Analysis of it, and what protections it provides to your business as an insured, is a matter of state law and often varies significantly from state to state. When faced with an important insurance issue, it is best to seek the counsel and advice of an experienced insurance professional or an attorney with experience in the insurance field.

Goes to College In April and May of 2011, graduates of San Francisco State University’s Master of Arts Program in Museum Studies held an exhibition entitled, Wings over the Pyramids: Will Egypt’s Treasures Survive? The exhibition included aerial and ground photographs of Egypt’s atmospheric conditions, dam construction and urban sprawl, together with valuable objects from the University Museum’s ancient Egyptian collections. During the development of the exhibition, Dr Linda Ellis—professor and director of the museum—contacted the editors of Concrete Openings regarding the magazine’s March 2009 cover story. The Return of the King described the cutting and removal of a statue of Egyptian Pharaoh King Ramses II in the center of Cairo before being transported back to the pyramids at Giza. Photographs and details from the job story were used in the exhibition. Over 600 visitors attended the one-month exhibition, including university faculty, university students, members of the general public and over 300 children (grades 6-12) from schools in San Francisco and San Mateo Counties. “Our museum exhibition benefited significantly from the valuable photographic documentation from the Concrete Sawing & Drilling Association,” said Ellis.

MIT Studies Focus on the Life Cycle of Concrete The Concrete Sustainability Hub at the Massachusetts Institute of Technology (MIT) released two studies in August that focus on the life cycle assessment (LCA) of concrete pavements and buildings. Both studies examine the cost and environmental impacts for the full life of pavements and buildings—including the use and operations phase. MIT also used this life-cycle approach to evaluate the real cost of pavement throughout a 50-year lifetime, beyond initial construction costs. MIT’s research showed that during a 50-year timeframe, the mean real price of concrete decreases by 20 percent, while the mean real price of asphalt increases by 95 percent.

MIT researchers also found that the carbon footprint of concrete pavements can be reduced. First, MIT developed a comprehensive methodology outlining the best-practice concepts that should be followed when conducting any pavement life-cycle assessment (LCA). The Hub researchers then applied these concepts to evaluate strategies to lower a concrete pavement’s carbon footprint and overall environmental impact. Finally, researchers reviewed fuel economy from a unique perspective. Instead of focusing on the efficiency of cars and trucks, they analyzed how pavement properties affect fuel economy. Pavements with greater stiffness mean better fuel economy for the vehicles that travel on them. MIT looked at typical material properties for concrete and asphalt pavements and found that for the same stiffness and fuel consumption, an asphalt pavement had to be up to 60 percent thicker than the concrete pavement.

MEMBER TESTIMONIAL We joined CSDA in 2002 because we were looking to forge relationships that would give the business a competitive advantage in the market. At that time, my partners, Matt Foley, John Krpan and I were in our mid-twenties and were just a few guys looking to build a solid business and have a little fun along the way. We learned about CSDA through an internet search, and after reading about everything the association offered we decided to give it a try. Like most things in life, membership in an organization like CSDA Dan Foley is what you make of it. The more you put in, the more you get from it in return. The information provided by CSDA through membership is great, but there is so much more if you are willing to become more involved. The people you meet at conventions and meetings, and the relationships you build, are where the real value comes in. We feel comfortable calling on our CSDA peers to ask for advice or to swap success and horror stories. We are also involved in the association’s Next Generation group, helping to introduce CSDA to a new breed of concrete cutters. When the company first signed up to CSDA, we had just a few trucks and equipment. Now we are running over 20 trucks and have expanded our cutting services dramatically.

CSDA 40th Celebration to be Held at World of Concrete

Patrick o’brien Executive Director

orld of Concrete (WOC) has become the rallying point for the concrete cutting industry, with manufacturers using this early-year show to introduce their new diamond tool

and machine offerings. CSDA has been a cosponsor of WOC for 35 years, joining just two years after the inaugural show. In January 2012, the association will once again take advantage of this gathering of concrete cutting professionals to hold events that are not to be missed. The anchor for these events is the CSDA exhibit booth in the Central Hall of the Las Vegas Convention Center (#C4457). All are encouraged to stop by the booth anytime during the show from January 24-27 to meet with fellow concrete cutting professionals, CSDA staff and Board and committee members. This year, in recognition of CSDA’s 40th Anniversary, a celebration will be held at 10:00 AM on Wednesday, January 25, with champagne, cake and presentations. Join CSDA President Jim Dvoratchek and the CSDA Board for this momentous occasion. Prior to the anniversary celebration, the CSDA Board will meet on January 25 from 7:30-9:00 AM in room Nxxx. This is a perfect opportunity to learn about CSDA as the Board reviews the accomplishments, of which there are many, for the recently completed year. The Next Generation group will meet on Thursday, January 26 at 9:00 AM in room N207 to set goals for 2012. If you would like to
