JUDITH O’DAY CSDA President

I

am honored to be the new President of CSDA. I have spent the last two years working as vice president and appreciate Jim Dvoratchek’s efforts during his tenure as President. His focus and capable management have helped CSDA successfully weather some very significant challenges over the past two years.

While some of these challenges are now behind us, I am prepared to take on those that remain and may arise in the future.

As I look forward to leading CSDA, I cannot help but look back at how far the association has come. In 1972, a group of contractors and manufacturers—many of whom were competitors—established CSDA. The focus of the group was to increase the use of sawing and drilling while promoting friendly relations within the industry. The foresight of these “founding fathers” was truly remarkable. Their vision of an organization comprised of competitors working together to improve the way work was being done, promote awareness of this new specialty market and increase contacts and friendship between contractors, is still viable. Not only has the industry grown in ways probably unimaginable in 1972, but the CSDA mission of promoting friendship within the industry has also probably surpassed what was anticipated.

w ww. c o n c re te ope n in gs.com

Over the last 40 years, the leadership and dedication of each new group of CSDA committees, elected Board members and Officers together with the CSDA management team has been exemplary. An amazing variety of programs, benefits, materials and resources have become available to CSDA members. These include safety manuals, educational DVDs, online and hands-on operator training, Toolbox Safety Tips, promotional materials and a dedicated trade publication—Concrete Openings.

Of even greater value, in my opinion, is the opportunity for extensive networking through CSDA membership.

The relationships that evolve at quarterly meetings, annual conventions and trade shows like World of Concrete are priceless. The ability to connect with a global membership and share ideas, expertise and problem-solving techniques is an exceptional benefit. Through the increased participation of current members and the involvement of new members, these gatherings will give rise to even more new ideas and innovations. This will not only fuel the growth of CSDA and its programs, but also its members and the industry as a whole.

As CSDA President, I look forward to working with the association’s Board, committees and members to growing its position in the industry and helping the membership maintain successful businesses.

A 25-foot by 25-foot steel pier section had sunk into the water.

Divers were used to inspect the damaged structure and set up the cuts.

n May 25, 2012, a large pier at a busy oil terminal in the Caribbean was struck by a tanker, causing severe damage to the structure. Part of the pier’s dolphin platform was left protruding approximately 5 feet from the water while the rest had sank below the surface. Three months later, the situation worsened when Hurricane Isaac blew through and caused the entire pier to sink around 6 feet below water level. Millions of dollars were being lost while the pier was not in use, so it was important the owner quickly removed and replaced it. In addition, the structure had become much harder to spot by passing ships, making it more suseptable to collisions.

w ww. c o n c re te ope n in gs.com

Two CSDA contractors joined forces to provide a solution that would not only remove the damaged structure from the water quickly, but in a way that was safer than other demolition methods and preserved the natural environment around the sunken pier.

Bahamas Oil Refining Company International Limited (BORCO) is the largest storage terminal facility in the Caribbean, with the ability to store, blend, transship and bunker fuel oil, crude oil and various petroleum products. Located off the southern tip of Grand Bahama Island in Freeport, the facility has a storage capacity of 21.6 million barrels.

c o n c r et e o pen i n g s | 7

A wire saw was positioned on a work platform 25 feet above the water.

BORCO provides services for shipping trade from all over the world, so when the Cape Bari—an 810-foot-long tanker—hit the pier, the company began losing millions of dollars while the damaged pier was out of commission. A solution was needed—and fast.

Bahama Industrial Technologies (BIT) was approached by BORCO to act as general contractor for the job. BIT began searching for a company that had the equipment and expertise to cut underwater and remove the sunken damaged sections of the pier deck. The general contractor invited CSDA member ABC Concrete Cutting—South Florida, located in Pompano Beach, to visit the terminal and come up with a plan to remove the sections. After performing a review of the site, ABC concluded that it would need additional resources for the job. The contractor reached out to fellow CSDA member Cutting Edge Services Corporation of Batavia, Ohio, and the two companies combined expertise to complete the work.

“Skip Aston [owner of ABC Concrete Cutting—South Florida] and I go way back and hold each other in high regard,” said Tim Beckman, owner of Cutting Edge Services Corp. “He wanted our underwater wire saw expertise to supplement his team’s work above the water, so we were happy to enter into the joint venture.”

8 | m a r c h.1 3

The submerged pier was unstable and the bottom sat approximately 30 feet below the surface of the water. The top of the section would break the surface during low tide and be around 6 feet below surface at high tide.

The damaged section consisted of a 1.5-inch-thick steel plate measuring 25 feet by 25 feet. The plate needed to be cut into three sections for a barge-mounted crane to lift it from the water and place on a work platform for disposal. The plate was connected to six 3-foot-high I beams, so cuts had to be made through each one to free the sections.

The ABC/Cutting Edge joint venture planned to deploy a diamond wire saw system to cut the damaged pier sections. The remote-operated saw would allow divers to stay a safe distance from the unstable structure, while mobilization and setup times were much quicker than other methods. BIT had attempted to use underwater torches to cut the structure, but the process took too long and the financial losses for BORCO were mounting.

A diving vessel with six divers and two crew members from Orion Marine was employed to support the work of the joint venture. Each day consisted of a 20-minute boat ride to the pier, where a work platform and crane barge were anchored in place. A modified WS25 wire saw from

Each wire saw pull cut took around six hours to complete.

Diamond Products was positioned on the work platform, standing 25 feet above the water. Divers entered the water and captured video to allow ABC/ Cutting Edge to assess the situation and create a game plan for the cutting work. Instructions were then given to the divers for the installation of the underwater pulleys, while the cutting team set up pulley stands on the work platform. Custom-fitted fenders were attached to some pulleys to prevent the wire from ‘jumping’ off while cutting underwater.

With the saw and pulley runs in place, divers began creating starting notches for the pulls using pneumatic power grinders. These notches were necessary, as the sunken plate was at a skewed angle underwater, making it difficult for the wire to get a “bite” on the steel. Diamond wire was run around the system, positioned in the notch and tensioned for the commencement of cutting. Crane rigging was also attached to the cut sections so that they could be lifted from the water once cut free. ABC/Cutting Edge used 140 feet of 10.3-millimeter-diameter (0.4 inches) wire from Tyrolit and ran the saw with 2,800 psi of pressure. Once the equipment and wire run was set up, each pull cut took approximately six hours to complete. Work commenced on September 10 and finished on October 1.

Ships continued to dock at nearby piers while cutting was performed.

Notches were made in the steel to help the diamond wire get a “bite� on the structure.

Cut sections were loaded on to work barges by crane for disposal.

Joe Bland was ABC’s project manager for the BROCO job. “We selected Cutting Edge to take the lead on this project due to their vast underwater wire sawing experience, which worked out extremely well for everyone involved. More importantly, there was a mutual trust and respect between the two companies.

This insured the project was completed in a timely fashion, to the best of our abilities and to the satisfaction of the customer.”

Working in the middle of the Caribbean may sound like an idillyc job location, but it was not without its problems. The team from ABC/ Cutting Edge experienced delays when rough, 6-foot seas interfered with the initial setup of the equipment and made the underwater environment very difficult for divers to operate.

Working underwater generally makes for a challenging jobsite, whether it be due to the speed of setup or the movement of damaged structures as was the case with this job. Another challenge was the removal of one particular The cut sections had spent months underwater in a damaged state.

section that was positioned directly underneath the existing structure.

This section had to be rigged to two cranes to safely remove it from the water without colliding with work barges.

Divers had all necessary PPE and workers on the platform were supplied with floatation devices, lanyards and harnesses. All personnel on the jobsite were briefed on the equipment and safety rails were put in place to prevent falls into the water. Gas detecting equipment was also used to ensure safe levels while cutting.

“I was extremely satisfied with the outcome of the job,” concluded Bland. “BIT was very pleased with our rapid response and our expedited mobilization. From the time that we looked at this job, we were able to mobilize and get all of our equipment through customs within a two week period.”

World of Concrete 2013 Innovation and Enthusiasm on the Rise The 39th annual World of Concrete trade show and exhibition was held in February 2013 at the Las Vegas Convention Center. For four days, the show was the focal point for almost 55,000 professionals from the fields of concrete construction and demolition. Attendance rose for the second consecutive year, and those who made the trip to Las Vegas got to see firsthand how new and innovative ideas continue to drive the industry forward.

N

ot only was attendance on the up, but so too was exhibition space. Over 1,200 manufacturers and distributors exhibited, covering in excess of 600,000 square feet. The Concrete Sawing & Drilling Association (CSDA) was present at the show, marking its 36th consecutive year as a cosponsor association, and its members filled over 40 booths in the three indoor exhibit halls and in the outdoor demonstration area. In addition, many contractor members attended the show to learn about new products and services that will give their businesses an advantage over their competitors.

New Products Over the past 12 months, several manufacturers have expanded on their range of tools and equipment or introduced products lines outside of their core area. One of these companies is Stihl, which launched its new GS 461 Rock Boss concrete chain saw at WOC 2013. This new chain saw weighs under 17 pounds without bar and chain, is capable of making 15.7-inch-deep cuts in concrete and can achieve 13,500 RPM. The company worked with fellow CSDA member Diamond Chain International to develop the chain technology.

Established concrete chain saw manufacturers like ICS were also exhibiting at the show, promoting the company’s FORCE4 series of diamond chains and introduced guide bars compatible with the Rock Boss. ICS also displayed its new line of ProFORCE diamond blades and core bits, developed in partnership with another CSDA member, Terra Diamond. Meanwhile, Diamond Products demonstrated its range of concrete sawing, drilling and grinding equipment. The company’s latest handheld cut-off saw, the FC8116 Fast Cut, has an 81cc engine, weighs 22 pounds and can accommodate a 16-inch-diameter blade. The gas-powered saw has a maximum spindle speed of 3,765 RPM.

Husqvarna Construction Products has expanded on the company’s range of demolition robots with the launch of the DXR 300. The new unit was on display at the company’s outdoor demonstration area. It weighs under 2,000 pounds and measures under 31 inches wide, allowing it to fit through standard doorways. The DXR 300 has a reach of 16 feet and produces 22 kilowatts of power. The remote control unit is connected to the robot via Bluetooth technology and has a 3.5-inch color screen. Also in the outdoor exhibit area was Brokk, Inc. The company displayed a selection of its demolition robots, including the smallest in the fleet—the Brokk 50. This 1,102-pounds robot was designed for interior jobsites and areas with limited access. Measuring just over 23 inches in width, the Brokk 50 can travel in passenger elevators and has a power output of 5.5 kilowatts.

Using a couple of innovative designs, Hilti, Inc. continues to evolve concrete anchoring systems. The company unveiled its new HIT-HY 200 adhesive anchor system at WOC 2013, which incorporates a vacuum connected to a specially-engineered hollow drill bit. Designed to extract dust from the hole while drilling, the aim of the system is to save the operator time and relieve his or her responsibility to clean the hole when completed. Hilti also demonstrated the capabilities of its range of cordless tools. The TE 2-A18 electric rotary hammer drill provides 360 watts of power and runs at a speed of 1,090 RPM under no load.

A head-to-head WOC demonstration saw the TE 2-A18 outperform a corded counterpart.

There was a wave of Dan Pherson introduces the GS 461 Rock Boss. enthusiasm throughout the show as manufacturers boasted significant increases in sales figures from previous years. Sustained efforts in research & development, along with investment in skilled employees, were cited as the main reasons for this upturn. The industry should expect further innovations in the future as many companies continue to explore new ideas.

CSDA/OSHA Alliance As a cosponsor of WOC, CSDA promotes the show, offers free attendee registration, exhibits and holds meetings at the convention center. In addition, the association shares its booth space with the Occupational Safety and Health Administration (OSHA) and has done so for the past seven years. This forms part of an Alliance partnership between the two organizations, aimed at raising awareness of workrelated hazards and encouraging the implementation of safety procedures and programs. During the show, Joy Flack of OSHA’s Nevada office gave a 90-minute seminar on revisions to the administration’s Hazard Communication Standard, sponsored by CSDA. Together, the CSDA/OSHA Alliance has created 10 documents to enhance worker safety in the industry. Several of these documents have also been translated into Spanish and all versions can be downloaded for free via www.csda.org. Click on the OSHA Alliance option under Safety.

The first ever CSDA Concrete Polishing class attracted 19 students.

Training Each year since CSDA held its first training class at WOC, a Wall Sawing 101 course in 2010, the association has expanded its training offerings in response to positive numbers. This year, the association scheduled three classes in Las Vegas and each attracted a lot of interest. A Core Drilling 201 Certification course, part of the association’s Operator Certification program, brought experienced operators together to perfect their craft and become certified in this discipline. Meanwhile, the CSDA Estimating class proved to be popular for the second year running, educating students about the role of an estimator in the sawing and drilling industry and teaching techniques that will help a company’s bottom line.

However, interest in the first ever CSDA Concrete Polishing class exceeded expectations and saw 19 students participate. Time was spent in the classroom and on the slab to demonstrate proper polishing techniques and educate students about how to correctly estimate polishing jobs.

It is hoped that this increase in training class participants continues and the CSDA Training Program expands accordingly. Following a few difficult years for many within the industry, it now seems that a confidence has returned to business owners. More cutting jobs are being tendered, jobsites are busy and companies are ready to invest in employee training again.

Husqvarna demonstrated its new Hiperfloor™ system.

Another draw to the CSDA exhibit booth this year was a series of raffle drawings. Prizes ranged from coffee mugs, t-shirts and back packs to champagne, fishing rods and diamond blades—all donated by CSDA member companies. “We were pleasantly surprised to receive so many raffle prizes from our members,” said CSDA Executive Director Patrick O’Brien. “I would like to thank DITEQ, Diamond Products, Diamond Tools Technology, Husqvarna, Patriot Diamond, Slurry Solutions and Western Saw for their generous donations.”

The main prizes however, consisted of a TS-092 Shibuya core drill, kindly donated by Norikazu Shibuya and DITEQ Corporation, and two 14-inch-diameter saw blades donated by Patriot Diamond. The winner of the core drill was Rita Ferguson of G&F Concrete Cutting, Inc. in Santa Ana, California. “I’m really thrilled to have won the drill,” said Ferguson.

“I visited the CSDA booth and picked up a ticket, but never thought I would be walking away with anything—let alone a great core drill!”

With WOC 2013 in the books, attention now turns to next year and the celebration of the show’s 40th anniversary. The Las Vegas Convention Center will once again host the event, scheduled for January 21-24, 2014. Based on numbers from the past couple of years, attendance is expected to increase once more and the quality and quantity of innovative products should also grow. The industry has a lot to be enthusiastic about.

Concrete Cutter Helps Stabilize Refrigeration Company’s Shipping Dock

A

t the Port of Mobile in Alabama, a massive concrete dock was shifting away from an adjoining warehouse building. A general contractor was asked to install a series of anchors in the earth below the dock to stabilize the structure. Help from a professional concrete cutter was needed to create 69 diagonal openings measuring 12 inches in diameter and 10 feet deep for the installation.

The contractor was responsible for drilling 12-inch-diameter holes in a concrete dock.

“Often we are presented with unusual challenges, but figure out a way to get it done.

This was one of those jobs�

Matthew Hephner, owner of Cuts, Inc.

Operators made three holes per day in the 1,500-foot-long dock.

1 8 | s e pte mb e r.12

Holes were drilled 10 feet deep at a 27-degree angle for the installation of earth anchors.

C O N C RETE

C A SES

In total, operators created 69 holes in 25 days.

A major supplier of refrigeration and logistic services for the food and retail industry, with 20 locations across North America, had been notified that action was required to stabilize a 1,500-foot-long dock at the company’s location in Mobile. The dock receives supplies from all over the world via the city’s shipping port, the only deep-water port in Alabama and one of the nation’s top ten largest ports by tonnage.

The Knoxville, Tennessee office of Hayward Baker Geotechnical Construction was contracted to install 10-foot-long earth anchors inside 10-inch-diameter sleeves for the stabilization of the concrete dock. Once the general contractor had devised a plan for the install, it began searching for a specialty contractor that could cut through the steel reinforced concrete structure and allow access to the ground beneath. CSDA member Cuts, Inc. of Knoxville, Tennessee, was invited to visit the site, review the job requirements and provide a solution. “Although we are a relatively small

w ww. c o n c re te ope n in gs.com

company with only 12 employees, we have established ourselves as a company willing and able to do any size job. Often we are presented with unusual challenges, but figure out a way to get it done. This was one of those jobs,” said Matthew Hephner, owner of Cuts, Inc. The contractor needed to create 69 holes to the specified dimensions of 12 inches in diameter and 10 feet deep at a 27-degree angle. Operators would be working from a barge positioned adjacent to the dock. An attempt was made to create the holes using large hammer drills. However, a combination of heavy steel reinforcement and a 2-inch-thick sheet pile embedded approximately 3 feet deep from the surface of the dock wall, together with working from a barge during changing tides, meant progress was slow and expensive. The dock was to remain in operation and the clock was ticking until the next shipment arrived, so another method had to be employed.

Core drilling with diamond tools was considered a much more suitable way

Cores weighing between 400 and 500 pounds were removed.

to create the holes quickly and efficiently. Furthermore, a drill stand could be mounted to the dock wall to eliminate movement experienced on the barge.

Another cutting contractor had already been on site and performed some drilling work, but was unable to complete the work as specified. The first task for Cuts, Inc. was to figure out why. Not only was there a steel sheet pile below the surface, but also a horizontal bar running through the concrete that was making it extremely difficult to remove the cut core.

After examining the steel detail drawings, operators determined it would be necessary to drill to a minimum depth of 6 feet on the first pull to cut through the problem bar. The contractor was faced with another challenge. Each diagonally cut core weighed between 400 and 500 pounds and needed to be removed. A custom core pulling device was fabricated, using the drill rig itself to lift out the cores.

With the gauntlet laid down by the general contractor, and with only a few days to mobilize, Cuts, Inc. got to work. With support from CSDA manufacturer member Hilti, Inc., the coring team was able to acquire 6-foot-

long, 12-inch-diameter core bits and have them shipped to the jobsite. Two Hilti DD500 electric hi-cycle core drills with extended posts were set up to create the first holes. The core puller attachment was fabricated in the contractor’s shop, while a bit cut-off and retipping station was fabricated on site to minimize down time.

In total, Cuts, Inc. performed 690 feet of concrete core drilling at the customer’s dock. Operators averaged three holes per day, taking approximately four hours to complete the cutting of each 12-inch-diameter hole to a depth of 10 feet. It took 25 days to drill all 69 holes and leave the site ready for Hayward Baker to install the earth anchors.

Despite working at a location owned by a refrigeration company, operators had to deal with heat on the jobsite. The work was done during the months of April and May when temperatures can average 80 degrees in Mobile. The contractor set up tents for shade and provided lots of drinking water for operators to remain hydrated. To prevent the core drill rigs from colliding with the barge during changing tides at night, they were removed

The concrete was heavily reinforced with steel, making cutting more difficult.

Company Profile from the dock wall and secured to the barge at the end of each shift. As for employee safety during working hours, Cuts, Inc. provided all necessary PPE for the job and supplied life vests for those working on or around the barge.

Not only was the job completed within the time frame specified, but it came in approximately 10 percent below the estimated cost. By exceeding the general contractor’s expectations in terms of speed and ability on this job, Cuts, Inc. has been awarded several more jobs through the same company.

“We took pride in the fact that Hayward Baker trusted us with such a crucial and time sensitive task. Even with considerable investment in equipment and diamonds, it turned out to be a very profitable job for us,” concluded Hephner.

With the core drilling work complete, the general contractor set up on the jobsite and successfully complete its tasks as specified, allowing the dock to remain open for the customer’s next shipment. The earth anchors installed at the dock will provide increased stabilization for many years to come.

Based in Knoxville, Tennessee, Cuts, Inc. has been involved with CSDA for several years. The company has been in business for nine years and offers the services of flat sawing, core drilling, wall sawing, wire sawing, hand sawing, grinding and floor preparation, selective demolition and excavation.

Maintaining Polished Concrete Floors

By Andy Bowman

W

e have reached a point in time where an increasing number of major retail stores, manufacturing facilities and government buildings are embracing polished concrete floors as the preferred choice for sustainable floor systems. When the decision-makers of these buildings enter into the specification and selection process, choosing the most viable concrete polishing system for the job, it is apparent that there are important features and benefits still unclear to them.

After speaking with many such end users about polishing systems, it seems the majority find the maintenance program of the floor to be the most confusing component. These specifiers are learning that maintenance programs differ greatly depending on the intended use of the finished floor and the daily impact of foot traffic on the system. For example, the foot traffic of a home improvement store may be equivalent to that of foot traffic in a grocery store. However, the introduction of other elements that cause micro abrasions, whether it be an accidental spill of shelved merchandise or exposure to sand or ice through extreme

2 2 | m arc h.13

hot or cold environments, will determine the frequency of cleaning to remove them. Fortunately for new end users of concrete polished floors, a lot of data has been recorded over the past several years that is specific to these two types of applications. This allows these end users to develop specifications for polished concrete floor systems and create an effective maintenance program with the contractor.

End users that do not enforce maintenance programs immediately after a polished floor system has been completed usually find themselves at a disadvantaged in the long term, especially when it comes to the appearance and sustainability of the floor. Some floor systems are unable to be completely returned to a “like new” state and ultimately need some form of corrective work within the first year of existence.

Polished concrete systems are not equal across the board, but they all share a common component. This component is important to consider and will provide answers when troubleshooting potential challenges regarding the selection of an appropriate maintenance system. All polished concrete systems

have what is referred to as a “return.” In this instance, the return refers to a specific time in the polishing process just before the sealer is applied. Having a floor at the maximum refinement before the guard or sealer is applied will not only naturally increase abrasion resistance, but will also require less maintenance afterward.

A flat floor without surface irregularities and scratches contains nothing for foot traffic and wheel traffic to grab onto. Polished concrete surfaces with 800, 1,500 or even 3,000 grit finishes may not necessarily be completely free of micro scratches and surface irregularities, and may require excessive amounts of polish guard and sealers to act as fillers.

Furthermore, It is important to understand if the polish guards and sealers being used are water soluble or not. If a sealer is used as a filler and is water soluble, wet foot traffic and normal floor maintenance with the use of an automatic floor scrubber will remove the sealer and reveal the return point of the floor. Proper surface refinement processes, in conjunction with proper sealers used as intended, will produce results that keep polished concrete a viable option for a durable and sustainable floor system.

To help educate those who offer concrete polishing as a service, or are considering the start up of a concrete polishing company, the Concrete Sawing & Drilling Association (CSDA) has expanded its membership to include polishing contractors and manufacturers of associated tools and equipment. The association has also added concrete polishing classes to its training program. The first of such classes was held at World of Concrete in February 2013, and the intention is to hold more classes in the future.

By participating in CSDA concrete polishing classes, contractors will learn how to eliminate the majority of risk factors associated with this discipline. For the first time in the history of the sawing and drilling industry, a course has been created to educate people on a technique outside the core disciplines. Now, a contractor can gain important knowledge from experienced CSDA instructors that will help him or her produce a polished floor that exceeds customer expectations. The aim is to give participants a model for producing floors to a consistent high level of quality, regardless of the type of concrete. Also, part of the class focuses on the maintenance of polished concrete floors and how contractors can work with customers to keep a floor system in the same condition it was when installed In addition to training, a polishing committee has been formed within the membership and CSDA plans to expand on its Standards, Specifications and Best Practices to include more documents specific to concrete polishing. Document CSDA-BP-008 Concrete Polished Floors has been in circulation since 2010 and is available for anyone to download in PDF from www.csda.org.

Polishing contractors, new or experienced, are encouraged to consider industry training. This will not only help them to create a high-quality polished concrete floor, but also give them the knowledge they need to set up an intelligent maintenance program for the surface. Over time, this will give customers confidence—their decision to install a polished concrete floor was a good one. As faith in this type of floor system grows, so too do the reputations of those contractors who install them and help customers maintain them correctly.

Cell Phone Tower Upgraded Through CSDA Connection

The core drilling of steel and concrete was needed to help reinforce a cell phone tower.

2 4 | m arc h.13

C O N C RETE

C A SES

A bracket was fabricated to help secure the drill stand on a small, irregular surface area.

A

series of precise holes was needed to reinforce a 150-foot-tall, 4-foot-diameter cell phone tower in Bristol, Connecticut.

The job would involve creating openings in the 2.5-inch-thick steel base plate of the tower and 84-inch-deep holes in the existing concrete base below it. A general contractor picked up the phone and called a specialty core driller to complete the work.

The core drilling of these holes would allow the general contractor to install reinforcing steel plates to the exterior wall of the tower and retrofit the base of the structure with gussets. The plan was to then use an epoxy to install 12 anchor rods, measuring 2.25 inches in diameter and 84 inches

w ww. c o n c re te ope n in gs.com

long, in the concrete base. This reinforcement would allow for the mounting of additional equipment and antennas without compromising the structural integrity of the tower.

Gratton Concrete Sawing & Drilling LLC, a CSDA contractor member, was chosen to cut 12 holes measuring 3 inches in diameter through the steel base plate. The contractor was then required to use a smaller, 2.75-inchdiameter core bit to thread through the holes in the base plate and drill the concrete base. Core drilling with diamond tools was the most suitable technique to employ on this project. The tower and base contained many coaxial cables for the transmission of phone signals, and there was also an unknown amount of steel in the concrete base. It was for these reasons that a cutting method with little vibration and debris was necessary. “We visited the site and formed a quote based on the information provided and asking some questions of our own, to be certain that the

c o n c ret e o p en i n g s | 2 5

customer had presented the job and its challenges accurately,� said Roger Gratton, joint owner of Gratton Concrete Sawing & Drilling LLC. The customer selected RIO Steel & Tower, Ltd of Alvarado, Texas, the general contractor for the job.

The core drill rig employed by Gratton’s operator consisted of a Hilti DD350 core drill, a stand and roll carriage from Diamond Products and core bits from Husqvarna measuring 24 and 48 inches long. In addition, the contractor used a carbide tip annular bit and a magnetic drill base from CS Unitec. Water was provided by the land owner and a generator was used to power the 220-volt core drill. The contractor custom engineered a core catcher using thin-wall tubing to remove the 84-inch-long concrete cores from the base.

There was no surface area on the concrete base sufficiently large enough to mount the core drill stand, and the ground surrounding the tower was soil covered with loose gravel, so Gratton fabricated a heavy steel bracket that allowed most of the drill stand to hang out beyond the base and keep it safe during operation. The top of the 8-foot-tall drill column was held firm to the tower using a chain and binder. Core drilling began and the contractor created 12 holes in the steel base plate of the cell tower, each measuring 3 inches in diameter and 2.5 inches deep. The operator completed this part of the job in four hours using the core drill rig and a magnetic base. It was now time to revert to a more familiar material—concrete.

It had not been specified whether the concrete base contained any steel rebar, so the operator proceded with caution. The core drill rig was mounted in line with one of the 3-inchdiameter holes in the steel base plate, and the operator started to drill the first of 12 holes 84 inches deep and 2.75 inches in diameter. While the core bit did not hit any rebar, the operator was surprised to find a 0.5-inch-thick steel plate approximately 82 inches deep in the base. The contractor was instructed to drill through the plate to the specified 84 inches at all 12 locations.

Drilling was held up only once due to segments breaking off from the bit and becoming lodged in the steel. Each hole took between two and three hours to drill and all coring work was completed in three 10-hour days. The contractor core drilled 30 inches of steel and 84 feet of concrete.

One minor setback for the cutting contractor was the rigidity of the drill stand and custom bracket. During the early stages of drilling, a subtle movement in the rig caused binding of the core bit. The contractor had to switch to a

An operator made 84-inch-deep holes in the concrete base of the tower using a 2.75-inch-diameter bit.

The holes created were for the installation of 84-inch anchor rods using an epoxy.

magnetic stand base to provide the required stability, allowing the 3-inchdiameter holes in the steel base plate to be completed in the same day.

Space on the jobsite was limited, but the combination of the custom rig bracket and the magnetic base meant the coring operation required a minimum amount of room. The support provided by CSDA manufacturer members, particularly CS Unitec, was very much appreciated by the contractor.

The project was completed on time and within budget. The professionalism and quick-thinking shown by the team from Gratton led to an additional request from the general contractor, which involved the installation of the anchor rods and the grouting of the tower’s base plate.

“This was our first project with RIO and I am very satisfied with how things went. Our bid was competitive, and our performance provided the general contractor a great first impression. I look forward to working with them again,” said Gratton. The business owner was pleased that his company could not only talk the talk, but walk the walk.

Blade Codes: Setting the Standard

By Judith O’Day

T

he CSDA Standards & Specifications Committee developed a blade code standard for the industry in response to requests from contractor members. The standard, CSDA-BC-107 Blade Application Code for Diamond Saw Blades, is devised for any blade used in the concrete cutting industry that is larger than 12 inches in diameter. Its purpose is to assist owners and operators to correctly identify the appropriate blade for a specific application.

The need for a standard was clear. Each diamond blade manufacturer has a unique set of identifying marks stamped on its line of blades. These markings may include coded information about blade application, matrix type and hardness, diamond concentration, a maximum recommended RPM, the direction of rotation and a serial number. Not only are the codes different for each manufacturer, but a manufacturer may use different markings

3 0 | m arc h.13

depending on blade application and the material each blade can cut.

It is also common for a cutting company to use blades from several manufacturers. Owners and operators select different blades for the specific job at hand. By using only the unique manufacturers coding to choose a blade, a saw operator may have difficulty determining the difference between a wall saw blade and a flat saw blade, as well as what application the blade is for; asphalt over concrete, cured concrete, green concrete, asphalt or block; in addition to wet or dry use.

CSDA Past President Ted Johnston of Di-Tech International, Inc. based in Winnipeg, Canada, was one of the first contractors to call for industry-wide blade codes and championed the Standard. “A big problem for me at the time was the misuse of blades. I had guys going out to several jobs, and they were picking out blades from the shop without knowing

if they were the right type of blades for the job.

There were no markings on the blades, and I had instances where wall saw blades were being used on a slab saw.”

The CSDA standard works to clarify and simplify the identifying marks on blades. The standard employs a simple three-category format, consisting of unique letters within the code that correspond with various applications. The letters are placed in a specific sequence separated by dashes. The first category identifies whether the blade is to be used wet only, or both wet and dry. The second category identifies the type of application, with multiple letters used on blades suitable for several applications. The specific saw type is identified by the third and final category.

This standard is recognized and endorsed by the Masonry and Concrete Saw Manufacturers Institute (SMI), a product-specific group of the Association of Equipment Manufacturers (AEM).

The exclusive letters to be used in the association’s Blade Application Code for Diamond Saw Blades are as follows: Position Description

Although implementation of the code is voluntary, manufacturers who have not yet embraced it are encouraged to review the Standard and assess how they may be able to include this code in their current identification marking process. A universal coding system will allow operators to be easily trained in blade identification and ensure that the proper blade has been selected for the job.

Proper blade selection for each job can improve both safety and productivity, as well as a cutting company’s bottom line. Making this selection more straightforward and understandable allows the correct selection to be made more often than not.

Husqvarna's AD 10 is a unique machine that enables hands-free drilling. The AD 10 works in conjunction with Husqvarna's DM 340 or DM 280 drill motors and DS 450 drill stand to alleviate operator fatigue while increasing performance. The addition of the new DM 340 110V model offers operators a high performance drill motor for all drilling applications. The AD 10 easily snaps into place at any angle on the drill stand. The operator oversees the feed direction and feed rate of the drilling operation through use of a single control knob. The machine can also sense when the drill head has gone through the material and then automatically stops both the power supply and drilling. When using the AD 10 instead of the crank feed handle, the operator can comfortably remain upright instead of leaning/bending over to operator the drill; this is especially helpful when drilling holes over 6" in diameter.

The Dangers of Energy Drinks

By Erin O’Brien

A

person can rarely turn on the TV, listen to the radio or flip through a magazine these days without seeing an advertisement for an energy drink. Some of the more recognizable brands include Monster, Rockstar, 5-Hour Energy and Red Bull. These drinks are often marketed towards teenagers and college students, but are often used by adults in order to get an extra “jolt” of energy to get through the workday.

Concrete cutting, scanning and polishing operators are no exception. Operators often work long hours and may start a shift early in the morning or work late into the night. Because these drinks offer a quick shot of energy, many operators will be tempted to forgo their usual coffee and grab an energy drink for a long day of work.

The problem lies with what the energy drink contains. The obvious ingredient is caffeine, offering that boost of energy. However, other ingredients are also present, including taurine, guarana (both stimulants) and B vitamins. The boost of energy you receive when consuming an energy drink comes from this combination of stimulants.

A typical cup of coffee brewed at home or at work contains about 100mg of caffeine.

A cup of Starbucks coffee has about 165mg of caffeine. According to Consumer Reports, safe limits of caffeine are up to 400mg per day for healthy adults, 200mg a day for pregnant women and up to 45-85mg per day for children, depending on weight. So if you consume more than four regular cups of coffee per day, you are at or over your limit. A recent test by Consumer Reports found that: · 5-Hour Energy contains 215mg of caffeine per serving · 5-Hour Energy Extra Strength contains 242mg of caffeine per serving · Monster Energy contains 92mg of caffeine per serving (2 servings per drink) · Rockstar Energy contains 80mg of caffeine per serving (2 servings per drink) · Rockstar Energy Shot contains 229mg of caffeine per serving · Red Bull Energy Drink contains 80mg of caffeine per serving

3 4 | m arc h.13

High doses of caffeine and other stimulants can result in restlessness, nervousness, insomnia and tremors. High doses can also trigger seizures and heart arrhythmias (unstable heart rhythms). All of these symptoms have been reported in cases of patient hospitalization following the consumption of an energy drink. Unfortunately, some of these hospitalizations have lead to permanent disability or even death.

From 2007 to 2011, it is estimated that the number of emergency room visits involving energy drinks increased from about 10,000 to more than 20,000. Most of those cases involved teens and young adults. Concerns over energy drinks have intensified following reports in the fall of 2012 of 18 deaths possibly tied to the drinks – including a 14-year old Maryland girl who died after drinking two large cans of Monster energy drinks. Concern is high enough that two senators are calling for the Food and Drug Administration to investigate safety concerns about energy drinks and their ingredients.

Although energy drinks represent only a small part of the carbonated beverage market, about 3.3%of sales volume, the growth of energy drink sales is quickly casting a shadow over the declining sales of soda. In 2011, sales volume for energy drinks rose by almost 17%, with the top three companies—Monster, Red

Bull and Rockstar—showing double-digit gains.

However, as sales rise, so do reports of adverse events suffered by people who use the products.

Some of these events include: · Death due to heart attack or suicide linked to 5-Hour Energy · A miscarriage linked to 5-Hour Energy · Convulsions, life-threatening fear, deafness and hemorrhage linked to 5-Hour Energy · Deaths due to heart attack or loss of consciousness linked to Monster · Hospitalization due to irregular heartbeat, severe diarrhea, migraine, psychotic disorder, heart attack and/or vomiting linked to Monster · Disability from irregular heartbeat or stroke linked to Rockstar · Hospitalization due to psychotic disorder, increased heart rate or loss of consciousness linked to Rockstar These adverse events were filed by patients, families or doctors and simply warn that the products may have harmed someone – but they do not prove that the product caused harm.

Often, energy drinks are a contributing factor in an adverse event, where other factors including physical activity, heat, nutrition and age may also play a role.

I can speak from personal experience on this topic. About five years ago, I was working as an athletic trainer for a high school in Florida. I was covering pre-season football practice during August, when temperatures rose into the 90’s and the heat index was over 100 degrees. One of the JV football players collapsed at the end of practice during conditioning drills. I immediately recognized the signs of heat stroke and called 911 (for more information on heat stroke and other heat-related illnesses, please refer to Preventing Heat Illness in the June 2010 issue of Concrete Openings.) My athlete was transported to the hospital, where we found out his core temperature had reached 106 degrees – a nearly lethal temperature. Gradually, his core temperature lowered and thankfully he suffered no longterm damage to his body, thanks to the efforts of the hospital staff and my actions on the football field. However, he was in the hospital for three days and was not able to return to the football team that season.

I later discovered that this athlete had not eaten lunch that day, and before practice had consumed a bag of Skittles and a Monster energy drink. The lack of “real” food, combined with the added sugar from the candy, caffeine and other stimulants from the energy drink and the extreme heat conditions during football practice most likely combined to cause him to have a heat stroke and ultimately, endangered his life.

While the energy drink was not the sole cause of this adverse event, it was most definitely a contributing factor.

Concrete sawing, scanning and polishing operators can be subjected to similar conditions while working outside or in a confined environment. Heat, sun, dehydration, poor diet and the consumption of energy drinks can combine to create a deadly situation. It is important to recognize the dangers of energy drinks and consume them responsibly, if at all. While cases of adverse events have been reported primarily in teenagers and young adults, anyone is at risk, especially when contributing factors are involved.

After the Race was Run Historic Racecourse Cut Using Diamond Tools

A

fter years of economic downturn, a bout of equine influenza and a long standing problem with the practicalities of its location, a famous harness racing club in Sydney, Australia, made the decision to relocate from its traditional home to more suitable premises. As a result, the land on which the racecourse stood was earmarked for a residential construction project and a cutting contractor was brought in to safely cut and remove 27 suspended concrete slab beams measuring approximately 27 meters long (88.6 feet), 2 meters wide (6.6 feet) and 1.5 meters thick (4.9 feet).

Harold Park Paceway, located in Glebe, Sydney, was one of the city’s iconic venues for over a century. Housing the NSW Harness Racing Club since 1911, the Paceway hosted countless meets and until the mid 1900s Harold Park was the major destination for harness racing in the country.

During the 1960s, crowds of 50,000 would pack the stands to watch the races. The redevelopment of the Harold Park site will create new public parkland, approximately 1,250 new homes, up to 500

new jobs and almost 2 kilometers (1.2 miles) of cycle ways. It will also conserve the heritage listed Rozelle Tram Depot, which operated on the site from 1904 to the 1960s.

The Harold Park Paceway was comprised of an 800-meter (2,624.7foot) track, a 3,000-seat grandstand and administration and parking facilities. CSDA member OzCut Concrete Cutting Services of Penrith, also a member of the Australian association (CSDAA), was contracted

by Hassarati & Co. Demolition & Excavation of Greenacre to remove the concrete support struts of the old Paceway track. “The suspended slab beams were constructed over a viaduct and consisted of hard to medium concrete with approximately 84 to 106 stress cables per beam, per cut,” said Steve Hill, operations manager for OzCut. The general contractor had placed a strict timetable on OzCut to keep the building project on schedule and minimize costs associated with employing an 800-ton crane for the job. It was important that the cutting contractor used a method that was fast, efficient and kept operators safe while working on suspended concrete structures. “We do utilize hydraulic systems on some jobsites, but we chose to use a high-frequency wire saw system purely to eliminate the weight factor. There were safety issues regarding working at height and accessibility to the work area by knuckle booms, so we had operators and site workers harnessed almost constantly,” added Hill.

By starting with an initial setup of three CS10 wire saws supplied by Husqvarna, two on one beam doing the cutting and one set up ready to cut on the next beam, the team from OzCut was able to reduce transition time between beams and allow operators to keep up a cut rate of six cuts per day. C1000 diamond wire was supplied by Husqvarna with a average length of around 20 meters (65.6 feet).

Each of the 2-meter-wide (6.6-foot) and 1.5-meter-thick (4.9-foot) beams required two cuts. Some of the beams also had 900-millimeterdiameter (35.4-inch) support columns attached that also needed to be cut. It took operators an average of one hour to complete one cut, with some taking up to 2.5 hours. Pulleys were used to create angled cuts to lift vertically, and some inverted cuts were performed.

Due to the lightweight nature of the wire saw system, the equipment was able to be moved by telehandlers and knuckle-boom excavators.

This further reduced the time needed to dismantle and reassemble the system between cuts.

Once the beams were cut, an 800-ton crane was positioned on site to lift the sections away from the work area. The average weight of the concrete sections was between 125 and 150 tons. While the cutting work went smoothly, there were some specifications that the contractor had to make sure it met.

Harold Park is deemed a heritage-listed site, meaning that all materials used on the site had to be environmentally friendly and have no impact on their surroundings whatsoever. The suspended beam was positioned over a creek bed, which had to be completely protected. The high-frequency wire saw system used was a lightweight conversion, consisting of only a single lead, water hoses and no need for large power packs traditionally associated with hydraulic systems. This eliminated the chances of any oil spilling into the creek, although the contractor did set up tarp covering to prevent any other type of debris entering the water.

Aside from the heritage restrictions, the cutting of a suspended concrete structure approximately 6 meters (19.7 feet) in the air was no easy task. All equipment required for the job had to be lifted to the work area and carefully placed. The size of the beams proved to be awkward, as they were not only incredibly large, but also narrow, at only 2 meters (6.6 feet) wide. This environment meant that only one operator could be

“We had used this method previously at another jobsite, where we were able to complete the whole project in five days despite the client estimating 30 days for the work. That is the honest truth! So we were confident that we could perform just as well on this job,” concluded Hill.

OzCut was able to keep to the strict schedule and finish the job ahead of time. Using this method of precise wire cutting with diamond tools, together with clever planning to speed up the transition process, operators were able to perform a large amount of cutting work in a short period of time. The innovative approach to the task allowed the general contractor to perform its work as promised and maintain the company’s budgeted overheads for the project.

SOCIAL MEDIA FOCUS

10 Ways to Grow Your Facebook Business Page Following

By Andrea Vahl

Has Your Facebook Page Growth Stalled?

Now is a good time to examine your Facebook activities, cutting out what isn’t working and expanding what works. Here are ten tips to help grow your Facebook community.

# 1: Connect with other page managers This is a powerful tactic to employ. Make a live connection with other Page administrators (admins) who have a similar demographic to yours and cross-promote each other. For example, if you are a concrete cutter with a Facebook Page, make a live connection with a GPR contractor in your area that draws similar clients (you may already know the owner of the other company). Then talk to him or her about

4 2 | m arc h.13

doing some Facebook cross-promotion and share each other’s posts with your audiences.

Joint ventures also help forge these meaningful connections. Host a webinar with another company that has a similar audience. This can be a great way to become visible to the other company’s audience.

# 2: Share original content Content is still king, and when people share your content, your Page name travels with it. Think of new ways you can add original photos, links or posts as part of your content.

Maybe it’s a screenshot from a hot tip.

Perhaps you use a photo from something happening behind the scenes at your business and ask people to provide a caption. You could also add an inspirational or thoughtprovoking quote to a photo. In any case, make

sure you are following photo copyright laws.

Many photos are branded with the name of the website or Page where it came from.

# 3: Tag your page from your personal profile Make sure it is easy for your friends to like your Page. As we know, Pages are not being seen as much in the news feed, so what is a page owner to do?

I recommend you post about your business occasionally on your Personal Profile.

If you tag your Business Page (type “@” and then start typing your Page name until you can select it from the drop-down menu that appears) rather than share the status, people who mouse over the Page name in your post can like the Page right from your update.

# 5: Add Facebook in your email signature How many emails do you send each day?

Again, this is not rocket science—just consider this tip as your gentle reminder to add a link to your Page in your email signature. Many email programs such as Gmail make it easy to customize your email signature with clickable icons, or you can use WiseStamp to make your email signature stand out.

# 6: Comment (thoughtfully) on other Pages as your Page This is a great way to get more exposure for your Business Page with a target audience.

Participate on other Pages where your audience is already having conversations. Find complementary Facebook Pages and like them as your Page, then watch your Page home feed and comment on the posts.

Use Facebook as your business the same way you use it personally: by interacting and having conversations as your Page.

Remember to add to the conversation and authentically build relationships. That will lead to those meaningful connections mentioned in point #1. This activity takes time and you may find only 10 minutes a week to do this. However, it is a good habit to form and will provide more visibility for your Page.

This is a very simple thing to do, yet so many people are skipping this step. If users are searching and finding your Personal Profile on Facebook, you want to make it as easy as possible for users to find your Business Page as well.

When people list where they work and it is not properly linked to their Facebook Page, a strange “Community Page” is created with that same name but with a suitcase icon. Then people start liking that Community Page rather than your real Facebook Page. All you need to do is to delete the Community Page from your Work and Education section in your About area (click Edit in the About section), then add in the correct Facebook Page.

sites like Kaywa and QRStuff. Use the link for your Facebook Page and you have automatically created a QR code that you can add to the back of your business card.

# 9: Advertise your Page on Facebook Today, there are many advertising options on Facebook. To get the best value for generating new likes for your Page, I would suggest you use a Sponsored “Like Story.” This will advertise your Page to friends of your current fans and give social proof in the ad by showcasing that the user’s friend likes your Page.

Sponsored “Like Stories” can be less expensive to run than an ad, but you won’t have any ad copy to help convert people into fans.

Hopefully, seeing that their friend likes you is a sufficiently compelling reason for that person to like you too.

Your sponsored “Like Story’ will be targeting the friends of your fans, but you can also use the regular Facebook targeting features to narrow the audience to your perfect demographic.

It is easy to create your ad and limit your budget, so you know how well it works before spending an arm and a leg.

Safety CountS

Confined Space Entry— Stay Safe in a Tight Spot

D

angerous conditions within confined spaces, if not properly identified and remedied, increase the chances of accidents and even fatalities. Accidents and fatalities occur in confined spaces when employees underestimate dangers or rescuers do not properly equip themselves to enter the space. These cramped workspaces are not intended for continuous employee occupancy and are usually entered when workers must perform a required inspection, repair, renovation, maintenance or similar operation that is an infrequent or irregular function of a larger industrial activity.

Many operators saw, drill, break, grind or polish concrete indoors, in areas of confined space or on jobsites with limited access. There are several areas of safety to consider when working in these types of areas, not just the safe operation of the equipment.

What is a Confined Space?

A confined space refers to a work area with limited openings for entry and exit and poor ventilation that can contain or produce dangerous air contaminants. Examples of confined spaces include storage tanks, pits, vaults, sewers, septic tanks, exhaust ducts, grain bins, boilers, pipelines and reaction vessels.

4 6 | m arc h.13

Hazards of Confined Spaces An atmosphere with too little oxygen is a dangerous condition, especially when working in confined spaces. An operator can be injured or killed within minutes if the oxygen content of the air is below 6%. Safe oxygen levels in the atmosphere are usually at 20.9%. An operator is at risk for asphyxiation when entering an atmosphere with oxygen levels less than 19.5%. Signs of an oxygen-deficient atmosphere include shortness of breath, impaired judgment, increased heart rate, vomiting and unconsciousness. Special equipment is needed to determine if the oxygen level is safe.

Confined spaces with toxic elements like carbon monoxide, flammable elements like butane or propane or even an atmosphere with too much oxygen are just as dangerous as an environment lacking oxygen.

A confined space with a sand-like substance can trap an employee in a matter of seconds. The substance can block an individual’s respiratory system or crush an individual to death. Once trapped in this substance, escape can become difficult.

Planning and Prevention A confined space permit is required when there is a potentially hazardous atmosphere.

This includes too little oxygen, too much

oxygen, flammable gasses, flammable vapors or toxic air contaminants. If the job is near a grain elevator or similar environment that has an engulfment hazard, this situation would require a confined space permit as well.

If working in a confined space that requires an entry permit, then a jobsite attendant is required. The attendant will oversee the job and continually monitor the hazards. The entry should be well planned with all potential threats carefully reviewed. Air quality testing should be done and an emergency plan should be communicated to all involved with the job. Ventilation and other requirements should be strictly enforced to ensure that safe working conditions are maintained in the confined space.

Do not wait until it is too late. If an operator is concerned about the conditions of the confined space, exit immediately and ask a supervisor to investigate.

CSDA provides a number of safety resources to protect industry professionals, whether working in confined spaces or other work zones. Members have access to over 100 Toolbox Safety Tips that cover, among other subjects, confined space entry, carbon monoxide safety and ventilation safety. In addition, the association has developed a 230-page safety manual to assist contractors in establishing safety and health programs for

the benefit of both employees and owners.

The manual is intended to provide a starting point for developing company-specific safety programs. It is divided into a Field Safety Manual, Reference Section and Q & A section.

For more information, visit www.csda.org or call 727-577-5004.

The Future of

Concrete Cutting Has Arrived

Carbon Monoxide Safety Tips Take the following preventative measures to avoid Carbon Monoxide (CO) poisoning: • Perform a survey to determine all sources of CO exposure.

• Do not use equipment that produces CO indoors or in enclosed spaces.

• Use an extraction system fitted to the exhaust pipe if an engine must be used indoors or in an enclosed space.

• Set up the equipment so that prevailing winds will blow exhaust away from the work area.

• Provide preventative maintenance on all gasoline-powered engines and tools.

• Monitor CO levels. If dangerous levels are likely, proper respiratory protection should be worn.

Taken from CSDA Toolbox Safety Tip 121 Carbon Monoxide Safety.

Exhaust Fume Facts Most four-cylinder gas or diesel engines powering concrete saws are around 150 cubic inches in size.

• If they are running at 3,000 RPM, they expel exhaust from each cylinder 1,500 times a minute.

• 150 cubic inches x 1,500 = 90,000 cubic inches of exhaust fumes.

• 90,000 cubic inches/1,728 cubic inches/cubic foot = 52 cubic feet of exhaust every minute x 60 minutes = 3,120 cubic feet an hour.

• A room that is 20 feet x 20 feet x 15 feet high contains 6,000 cubic feet of air.

• In less than two hours, the engine would replace the fresh air in this room with exhaust gas.

SpiderCut Span Saw

If straight lines, proper depths, and most of all High Level Production are part of your industry’s demands, the Spidercut™ Pavement Span Saw sets the pace for today’s concrete pavement cutting systems.

It is very difficult for anyone to estimate the exchange of air inside of most buildings. This is why CSDA strongly recommends the use of electric saws when working inside.

Hilti recently launched the Hilti HIT-HY 200 Adhesive Anchor System. Incorporating the company’s Safe Set™ Technology, the system has been designed to improve the performance of anchor holes by eliminating manual hole cleaning. Operators can use the new Hilti TE-CD and TE-YD hollow drill bits in conjunction with a Hilti VC 20/40 vacuum system. Dust is removed by the vacuum while drilling is in progress, enabling faster drilling and a virtually dustless working environment. This new method of installation is to be used in conjunction with the Hilti HIT-HY 200 adhesive. In addition, a new Hilti HIT-Z cleaning rod comes with a cone-shaped helix that works as a torque-controlled anchor. The shape of these components allows the anchor to be installed in a standard hole—hammer drilled, dry or water saturated concrete, above 41 degrees—without being cleaned. The system is available in two versions for regular or accelerated working times. For more information, contact Hilti customer service at 800-879-8000 in the U.S., 800-461-3028 in Canada or visit www.us.hilti.com in the U.S. or www.hilti.ca in Canada.

Hilti TE 2-A18 Rotary Hammer Drills

CentralPoint Solutions Introduces Mobile App CentralPoint Solutions, LLC, a provider of centralized information management software designed to improve efficiency in concrete cutting jobs and operations management, is excited to announce the introduction of a remote connectivity solution to compliment the company’s CenPoint software. CenPointMobile is an Android app designed to interface smartphones and tablets with the CenPoint software program. CenPoint-Mobile provides a live display of the user’s work order assignments, and by using the app the user does not have to rely on texting, emailing or printing. A company dispatcher simply creates a dispatch assignment and the user, whether a project manager or operator, receives it live on their electronic device via the CenPointMobile app. The company provided live demonstrations of the new app during World of Concrete in February. For more information about app features, or a demonstration, contact Jay Shaver at 801-478-6822 x302 or email sales@cenpoint.com.

The Hilti TE 2-A18 rotary hammer drill is available in a lightweight, compact size or a larger size for more run time. It is claimed the TE 2-A18 compact rotary tool is the first compact SDS plus tool on the market that drills like a corded tool. Both models have high efficiency motors that deliver more work per charge and weigh less than their corded counterpart, the Hilti TE 2. These tools are ideal for drilling anchor holes or through holes in concrete, brick and block with an optimum drilling diameter range of 0.188 to 0.375 inches. Hilti CPC battery technology protects the battery, switch and motor while a drop-resistant ultramide housing has been designed to protect the tool’s vital components. For more information, contact Hilti customer service at 800-879-8000 in the U.S., 800-461-3028 in Canada or visit www.us.hilti.com in the U.S. or www.hilti.ca in Canada.

MEMBER TESTIMONIAL We are a fairly new member of CSDA, joining in 2012, but I can honestly say I am glad we are part of the association. Right away I began utilizing information like the Toolbox Safety Tips and training resources provided through our membership. I have been a Concrete Openings subscriber for a few years and have spent time reading through the online discussions forums on the CSDA Website. However, what I really needed was to find peers that may have been, or are going through, similar situation to myself. Now, as a member, I can see that all this and more is available to me.

When I saw that CSDA was holding its quarterly meetings near to my location, I decided to attend.

Everyone was so welcoming, which encouraged me to ask questions and bounce ideas. The responses I received reiterated what I knew all along; the more involved you become the more benefits you receive. I have read many member testimonials stating that the relationships built through being a proactive member are invaluable. I strongly believe that my membership in CSDA will strengthen my company and be an integral part of its success.

director’s dialogue

Change, Change, Change!

Patrick o’brien Executive Director

I

t seems that in each of the past five years, many have looked to the annual World of Concrete show as a forecast of what business activity will look like in the concrete segment of the construction industry for the upcoming year. The sentiment from exhibiting manufacturers at this year’s World of Concrete was very positive and attendance rose 6% to 54,869 from the previous year. Will this year be a good one for those in the concrete business?

Looking at how the World of Concrete, or the industry as a whole, performs, it might not give a true picture of how individual companies will perform. Many companies in the past were content to look at market performance and accept that their sales would be up or down with the market growth or decline. But others felt that they had to change their way of doing things.

A recent email addressed the fallacy of not changing. Hanley Wood Vice Chairman Frank Anton’s email article, entitled A Bigger Piece of a Smaller Pie, suggested that “One way to protect yourself in a declining market is to get a bigger piece of a smaller pie.” Hanley Wood is no stranger to the concrete business, as they run the World of Concrete show and have a vast experience in the construction market. Anton went on to explain how many home builders during the 2007-2012 downturn lost business because new home sales that typically account for 15% of all homes sold dropped to about 7%. If you didn’t change, your business revenue would have been down by 50%!

CSDA and many of its contractor members have not waited for the pie to grow bigger, but have instead decided to change their own destiny

6 4 | m arc h.13

by adding services to grow annual revenue, whether the overall market grows or not.

Many CSDA contractors have expanded their services by adding selective demolition, ground penetrating radar imaging and concrete floor polishing. The successful contractor of the future needs to expand his or her business beyond the traditional services, i.e. grow the pie, to thrive! One contractor told me at the World of Concrete that the addition of selective demolition services has boosted his company’s sales.

In addition, the company’s traditional sawing and drilling services have also grown because of opportunities that have arisen from adding new demolition services.

CSDA recently expanded its membership categories and redefined how it identifies contractors, in response to this change in the construction market. The association’s membership directory identifies contractors by the services they offer such as flat sawing, core drilling, wall sawing, wire sawing, curb cutting and selective demolition. This past year, two new categories were added for concrete polishing and ground penetrating radar imaging contractors.

Business activity may not return to the lofty levels experienced in the “good times” anytime soon, but CSDA contractors have proven that they know how to adapt and change to take charge of their own destiny.

Many are getting a bigger piece of that smaller pie.

Best wishes in changing your business to grow your piece of the pie in 2013!
