Horizontal and vertical wire saw cuts provided a clean finish on the foundation walls.

he scheduled demolition of concrete structures, some 400-feet-tall, at a NASA static engine test stand began with the use of explosives. However, more safe and accurate methods were required to bring the structures to set elevations and maintain the foundations for reuse. By the end of the project, one cutting contractor had completed over 400 feet of hand and wall sawing, core drilled in excess of 70 holes and used a wire saw to cut over 2,100 square feet of reinforced concrete.

Redstone Arsenal is a United States Army post located in the Tennessee Valley Region of Alabama, near the city of Huntsville. The Arsenal is a garrison for a number of tenants including the United States Army Material Command, the Army's Aviation and Missile Command, the Missile Defense Agency of the Department of Defense and NASA's Marshall Space Flight Center. Redstone Arsenal spans over 38,000 acres and includes a 7,200-foot-long airfield runway. It houses a government and contractor workforce that averages 36,000 to 40,000 personnel daily.

The contractor performed over 2,100 square feet of wire sawing.

The static engine test stand, located in the Marshall Space Flight Center West Test Area, contained two concrete towers standing 400 and 300 feet tall. The stand was deemed outdated and required reconfiguring to test new engines for future space programs. The foundations required approximately 150 linear feet of cutting on each side, and in each corner were 14-foot by 14-foot caissons. On the east end of the stand was a basement area that housed mechanical, electrical and fuel sources. This part of the structure was separated by a concrete wall that was 5 feet thick in some areas.

Following the use of explosives by demolition contractor Britt Demolition of Birmingham, Alabama, the general contractor for the

project, Brasfield & Gorrie of Birmingham, required that all remaining structures and foundations be brought to a finish point. These remaining foundations were going to be used as part of the construction of a new stand, so they needed to be free of structural damage and the finish points had to be clean and precise as per the job specifications.

Britt Demolition contracted CSDA member International Drilling & Sawing, Inc. (IDS) of Montgomery, Alabama, to perform precise diamond wire saw cuts that would provide the necessary levels of accuracy for the work. The specialty cutting contractor was to bring all the foundations of the two demolished towers to elevations ranging from 4 feet to 18 feet above grade within a 32-day window.

Marshall Space Flight Center NASA’s Marshall Space Flight Center is situated on the U.S. Army’s Redstone Arsenal in Huntsville, Alabama. The center’s history reaches back to 1957, the year before NASA was created, and was established partially in response to the Soviet Union’s launch of the first artificial satellite, Sputnik, in 1956. A group of Army employees working then on rocket and missile programs at Redstone Arsenal included a team of German scientists led by Dr. Wernher von Braun. Dr. Braun was largely responsible for the successful launch of the United States’ first satellite, Explorer 1, in 1958. In 1960, NASA established the Marshall Center with the transfer from the Army of more than 4,500 civil service employees and nearly 2,000 acres of Redstone Arsenal property.

Marshall minds designed, built, tested and helped launch the giant Saturn V rocket that carried astronauts on the Apollo missions to the moon. Marshall developed new rocket engines The Lunar Roving Vehicle was designed and and tanks for the fleet of space shuttles, built sections of the International Space Station (ISS) and now manages all the scientific work of the astronauts aboard the ISS from a 24/7 Payload tested at Marshall (photo courtesy of NASA).

Operations and Integration Center. It is also currently the development home of the Space Launch System (SLS), the most powerful rocket ever designed to carry human explorers, their equipment and science payloads deeper into space than ever before—to an asteroid and to Mars. Marshall manages the Michoud Assembly Facility, where the core stage of SLS is under construction with a unique set of leading-edge tools, including the largest spacecraft welding tool in the world, the 170-foot-tall, 78-foot-wide Vertical Assembly Center.

K2DiamondMatrixTech_K2DiamondAd-10/08 4/9/15 7:59 PM Page 1 “Concrete cutting was specified because precise finishes were needed at the proper elevation and the work had to be done without the destruction or damage of the remaining foundations,” said Roy Nelson, production manager for IDS. “Other methods like explosives and track-mounted breakers were used to bring down the towers to within 10 feet of the foundations, but from that point forward a more refined method was needed.”

A survey crew from Brasfield & Gorrie determined elevation points and established cut lines. From this point, the team from IDS began their work. The first task was for core drilling operators to create a series of 1.5- and 2.5-inch-diameter holes in the foundation walls that ranged from 24 to 60 inches thick using a Shibuya TS-402 core drill supplied

by DITEQ. These holes would be used for diamond wire runs so the wire saw could perform cross-sectional pull cuts through the concrete. On average, these holes took around 30 minutes to drill for the thinner walls and up to 90 minutes for the thicker ones. The contractor cored 74 holes in total.

With all core holes complete, IDS used a Diamond Products WS-25 wire saw and two Hydrostress SB wire saws for the cuts. Pulleys were positioned and the wire was threaded through, ready to begin cutting. Horizontal pull cuts measuring between 10 and 14 feet long were made through the foundations walls, taking an average of five hours to complete.

Operators also made a series of vertical cuts that ranged from 3 to 12 feet tall to account for elevation changes within some of the remaining structures, such as cutting around door openings. The wire sawing portion of the work accounted for 2,102 square feet of concrete cutting. During these cuts, IDS encountered two, sometimes four mats of 2-inch-diameter rebar on 8-inch centers. In other areas, the reinforcement consisted of #14 rebar on 8-inch centers.

Wall sawing techniques were used to cut top and end sections from three separate concrete trench boxes that housed mechanical, electrical and fuel supplies. This task took two-and-a-half days to complete.

The walls and floors were 12 inches thick with two mats of #8 rebar on 12-inch centers.

It was specified that some sections of the foundations structures be scored at 3 feet below the cut lines. This was so that the concrete between the scored lines and the cut line could be chipped out by the demolition contractor, exposing the

K2 DiAmOnD MATRIX TECHNOLOGY™...The Art and Science of Sawing & Drilling Tools

Not all jobs are tough and not all jobs require diamond tools…

This was a tough job requiring the removal of a 72” long by 14” diameter solid steel pin from a lock and dam gate hinge. Frozen in place, the Corp Of Engineers determined that drilling the massive pin out was the only option. K2 engineered a tungsten carbide drilling system to drill out the solid steel pin. The carbide tipped 13.750” diameter core bits ranged in length from 14” up to 72”.

Special guide rods were installed in the center of the bits to guarantee absolute straight and true holes. K2 and a CSDA contractor solved a huge problem for the Corp and saved them a ton of money and time.

Our experience and our expertise are what the art and science of Matrix Technology™ brings to the table for you!

steel reinforcement. This steel was used by the general contractor to tie back into during construction of the new test stand.

IDS performed 174 feet of hand sawing at the jobsite from depths of 2 inches to 10 inches using a Core Cut 16-inch hand saw from Diamond Products. Where necessary, operators worked from an all-terrain scissor lift and were tied off at all times.

The cutting work was scheduled during the months of July and August 2014, which

are often hot and stormy months in Alabama, with average high temperatures of 91 degrees Fahrenheit. IDS, being a local contractor and used to this type of environment, took the necessary steps to protect workers while working in the summer heat—especially those working below grade where there was less wind to cool operators. The team was able to work through the unsettled weather, but incurred some downtime when conditions deteriorated. NASA representatives monitored

the area for lightning and severe weather activity, and notified all contractors when necessary. Although unavoidable, this downtime meant less time to complete the work.

Britt Demolition had been given 35 days to complete this phase of the project, which was quite a tight time frame given the size of the task. The demolition contractor continued its work while IDS was on site, which created some uneven ground surfaces for the cutting contractor to work from. After the first week of cutting, IDS was asked to provide more crews and work seven days a week to keep within these time constraints. Once the cutting contractor increased its presence at the test stand, the work was completed on time and without incident. Daily Job Safety Analysis forms were completed and discussed before cutting commenced, and was just one of the reasons why the work was completed safely.

“Our knowledge of wire sawing techniques and our ability to work within these types of government installations helped us win this project. We had a good relationship with the general contractor, understood the scope of work and were able to quickly adapt when needed,” said Nelson. “I would like to give mention to Jeff Doss, Wes Henry, Matt Jeffers, Jason Weaver, Michael White and Travis Wilson for going above and beyond to get this job done,” he concluded.

The new static engine test stand at NASA's Marshall Space Flight Center within Redstone Arsenal is near completion, and will soon allow the Agency to assess state-ofthe-art rockets and engines for future space programs.

Operators worked from all-terrain scissor lifts to complete some of the work.

Clean Cutting in Pittsburgh CSDA Member Makes Water Treatment Retrofit Work

1 6 | J U NE .1 5

A unique and challenging job was performed by a specialty contractor that involved 834 square feet of concrete wire sawing and the removal of cut sections weighing approximately 26,000 pounds.

When you flush a toilet in Pittsburgh, Pennsylvania, the waste water eventually ends up in the main intake (wet well) at the Allegheny County Sanitary Authority (ALCOSAN). The wet well is cylindrical in shape, measuring approximately 40 feet in diameter and is 120 feet deep. It is a smaller tank situated within a larger cylindrical shell that houses various electrical services, piping and an access elevator. A scheduled retrofit of equipment within the wet well involved the precise cutting of a large concrete footer using diamond tools.

At the bottom of the wet well are six separate 36-inchdiameter distribution lines, which spoke out from the bottom of the tank into the outer shell. Each line runs straight up to the top and transfers sewage to processing stations at a rate of 128,000 gallons per minute. To push the waste water up these 120-foot vertical lines at this rate, the facility has six 2,000-horsepower transfer pumps. To mitigate any movement of the pumps while in operation, the elbows at the bottom of the tanks are embedded deep in concrete.

One of the pumps had reached the end of its service life and was scheduled to be replaced. This meant that sections of plumbing, including the existing 36-inch-diameter concreteembedded elbow, also had to be removed.

For the retrofit, the new pump system required that the footer be notched large enough to remove the existing pipe elbow and provide adequate room for the new plumbing system. The notch was 10 feet long, 13 feet wide and 8 feet deep.

The replacement of this pump was scheduled to be done during a two-week plant shut down from January 28 to February 10, 2015, therefore time was of the essence.

General contractor Kokosing Construction Company, Inc. of Westerville, Ohio, and lead subcontractor Noralco Corporation of Pittsburgh began the search for a skilled cutting contractor to make the necessary renovations to the concrete footer. CSDA member Matcon Diamond, Inc., also of Pittsburgh, was chosen for the work. “This was an interesting job to work on. The method for removal was unspecified by the owner's designer.

Only the dimensions of the void for the new pump were listed. Noralco had planned on breaking the slab apart by hoe-ramming, expanding chemical compounds and

Diamond wire sawing techniques were used to cut the footer and around the elbow of the pump line.

A 10-foot-long, 13-foot-wide and 8-foot-deep notch was to be created in the wet well’s concrete footer.

hydraulic rock splitters, but they approached us to devise a quicker and more cost effective method utilizing diamond tools,” said Jon Wilson, project manager for Matcon. “The only feasible way to complete the work in such a short time period was to cut the footer into 11 large pieces—diamond sawing was the only method that could accommodate that schedule.”

Upon commencement of the pump shut down, the general contractor had a full week of selective demolition and removal tasks related to the supporting plumbing structures.

As access to the area was denied until the shut down, and no wire sawing could be completed while dismantling work took place, the first shift of cutting work consisted of core drilling 12 access holes for wire and plunge cut pulleys. Operators drilled eight 9-inch-diameter holes 8 feet deep, two 4-inch-diameter holes 13 feet deep and two 2-inch-diameter holes 4 feet deep. This took An operator next to one of the 8-foot-tall cut sections.

Located along the Ohio River on Pittsburgh’s northside, the Allegheny County Sanitary Authority (ALCOSAN) provides wastewater treatment services to 83 communities including the City of Pittsburgh. ALCOSAN’s 59-acre treatment plant is one of the largest wastewater treatment facilities in the Ohio River Valley, processing up to 250 million gallons of wastewater daily. The Authority was created in 1946 under the Pennsylvania Municipal Authorities Act and began treating wastewater in 1959. Secondary (biological) treatment processes were added in 1972.

It has 320,000 residential, commercial and industrial accounts representing a service population of 900,000.

ALCOSAN recently completed a $400 million capital improvement program which addressed odor control, treatment capacity, solids handling and wet weather planning.

long and 8 feet deep, taking eight hours to complete. The wire, supplied by K2 Diamond, was then pulled horizontally towards the wet well to create the bottom cut line before a series of pushed longitudinal and transverse cuts were made to create the 11 cut sections.

Matcon made 10 cuts ranging from 48 to 130 square feet for a total of 834 square feet. The wire saw averaged 14 square feet per hour and the average weight of the 11 pieces was 26,000 pounds.

With all wire sawing work completed, Matcon began to extract the cut pieces using an on-site 20-ton gantry crane, leaving only the final piece with the embedded pipe elbow in place. As this piece was now exposed and the only one remaining, the concrete was chipped away from the pipe using a Husqvarna DXR 310 demolition robot. This was the only suitable method to remove this final section, as in its entirety it was in excess of the crane's lifting capacity.

The removal of all cut and broken concrete pieces was a challenge for the contractor. The gantry crane was situated inside the shell, but in order to completely remove the pieces from the structure, each one had to be handled a second time. This involved picking them through a 12-foot by 12-foot access hatch in the roof using an outside crane. Moreover, the weight and dimensions of the pieces caused some extra concern on removal. Specifically, the largest pieces were roughly 5-foot by 5-foot by 8-foot columns of non-reinforced concrete weighing around 26,000 pounds.

With a lack of reinforcing, deep mechanical anchoring was required to ensure that gravity would not pull the slab apart as the pieces were extracted.

Another challenge was the removal of additional concrete pieces below the bottom horizontal cut. The horizontal wire cut could only be made flush with the floor of the building. However, specifications for the new replacement pump unit required a complete encasement in concrete. Therefore, once the first 8 feet was removed Matcon operators had to essentially "spoon out” a 12-inch-thick concrete floor area measuring 13 feet by 10 feet. Rather than wire saw this area, it was determined the fastest method was to flat saw the concrete into a grid at the required depth.

The operator used a 40-horsepower electric flat saw from Diamond Products fitted with a 26-inch-diameter blade for the cuts. This created sections approximately 12 inches cubed that were broken out using the DXR

The ALCOSAN wet well job required all units to be powered electrically. Given the 120-foot depth of the structure, it would have been almost impossible to use combustion equipment—even with the use of exhaust scrubbers.

Core Drilling on the

Mississippi River Lock & Dam No. 11 Renovation Project

2 2 | J U NE .1 5

A professional cutting contractor was tasked with drilling out over 38,000 pounds of steel when the pins of six large lock gate hinges on the Mississippi River became stuck in their bushing and would not allow the gates to rotate properly.

This issue would eventually lead to the failure of the gates, so the contractor was therefore tasked to core drill the twelve 6-foot-long, 14-inch-diameter pins from the gate hinges within 0.125 inch of the outside diameter and without piercing the sides of the pins. After the drilling work was complete, the twelve 0.125-inch-thick steel cylinders that remained would be removed and new lock pins installed.

The job was at the General Zebulon Pike Lock & Dam No. 11, which is located between Dubuque, Iowa, and rural Grant County, Wisconsin, on the Upper Mississippi River. The structure was designed and constructed under the direction of the U.S. Army Corps of Engineers between 1934 and 1937.

The main lock is 110 feet wide by 600 feet long while the entire Lock & Dam No. 11 system is listed on the National Register of Historic Places. The movable portion of the dam is 1,478 feet long and consists of 13 tainter gates and three roller gates. The non-movable part is a 3,340-foot-long, non-overflow earthen dam that is connected to the Wisconsin shore.

Commissioned by the Army Corps of Engineers, a plan was developed to replace the steel pins within the lock gate hinges and general contractor J.F. Brennan Company, Inc. of La Crosse, Wisconsin, was chosen for the work. The general contractor then awarded Minneapolis Concrete Sawing & Drilling (MCSD) of Brooklyn Park, Minnesota, the task of cutting the old 6-foot-long steel pins free.

Each of the bits had special built-in guide tubes fitted to allow for precise drilling through the lock gate hinge. Core drilling began with a 14-inchlong bit. Once the operator had reached the maximum drilling depth of the bit, he backed out of the cut and replaced the bit with a 24-inch-long equivalent. This process was repeated an additional two times, using 48-inch and 72-inch-long bits respectively.

Drilling of the first pin was planned as a two-week project so that the team from MCSD could modify and optimize the drilling process before progressing on to the others. First, the flow of hydraulic fluid was controlled by partially closing valves, but this resulted in the bit surging or hammering and dulled the carbide teeth prematurely. Once the contractor obtained the most suitable equipment and reached the

The pins in the lock gate hinges had become stuck in their bushing and were not properly rotating.

It was crucial to the project that the surrounding lock structure remain undamaged during the work, as any loss of structural integrity could have resulted in the total replacement of the gate assembly.

Therefore, the use of high percussion methods or tools utilizing extreme heat or cold were deemed unsuitable. Any work had to stay within 0.125-inch outside diameter of the pins so as not to compromise the surrounding structure.

A hydraulic core drill was utilized for the work. Spinning at a rate of 50 RPM, the drill was equipped with a series of four 13.875-inchdiameter carbide core bits provided by CSDA member K2 Diamond.

optimal RPM for the application, drilling time for each pin was reduced to four days. This included travel time to the jobsite, positioning of tools and equipment by crane, the setup of the drill rig and the removal of all items before leaving the site and returning to Minneapolis. Actual drilling time of the pins was completed in two eight-hour shifts, which also included the switching out of four different sized bits.

The drilling process was repeated on all six lock gates, drilling out twelve pins in total. Additional carbide tips were provided by K2 Diamond and the barrels were re-tipped before coring commenced on the next pin. This is because drilling metals such as steel causes greater friction than when drilling concrete. This increased friction produces higher temperatures within the cut that dull segments and reduces cutting efficiency. For this particular job, core bits with carbide tips were seen as a better option than those with diamond segments and were found to provide better results.

Core bits were regularly re-tipped to maintain cutting efficiency.

Metal filings were collected in a 50-gallon drum and recycled off-site.

The carbide tips were set on specific angles onto the barrel and were used in a manner that would more closely resemble milling the metal than drilling it. The only way to economically accomplish this project was for the contractor to re-tip the barrels as the carbide tips became dull and their ability to penetrate the material lessened. The built-in tubes and guide pins needed to be matched up as a set to allow each bit to follow the other, making it cost prohibitive to re-make the tube sets each time the tips dulled.

After a pin was drilled out, the slug was pulled out by crane. Each slug weighed approximately 3,200 pounds. A hand grinder was then used to score the remaining 0.063-inch of steel, allowing the shell to be folded in and removed from the pin hole. Since working over water, steps were taken to catch the metal filings created by cutting. It was specified that these filings should not be discharged into the river, so a 50-gallon plastic drum was modified and a rain gutter assembly was run out the side. This allowed water to return to the river while the metal filings were retained in the bottom of the barrel. The filings were removed from the jobsite and eventually recycled.

“Fear of damage to the pin housings ruled out the possibility of using heat or freezing techniques to shatter these pins. Carbide-tipped core bits were the only way this project was going to be accomplished. With a unique project like this, I needed some further input so I contacted K2 and got some help,” said Jim Fuglie, owner of MCSD. The Lock & Dam No. 11 Renovation Project shows the effectiveness and versatility of tools and equipment used by specialist cutting contractors. While these tools are often used to cut large quantities of concrete with steel reinforcement, they are also capable of cutting through thick sections of steel as well—if handled correctly. This sawing and drilling contractor used its experience and skill to complete a challenging job on time.

Getting the Most from Your Demolition Robot

By August Scalici

R

emote-controlled demolition robots are becoming increasingly popular among concrete cutters around the world. They can be operated in confined spaces, often with limited access, and by their very nature they allow operators to position themselves a safe distance from potential worksite hazards. In addition, most models emit zero emissions.

Their very high power-to-weight ratio and precise controls make them an invaluable tool for interior selective demolition jobs.

Combined with more traditional cutting and coring operations, they can expand the market for concrete cutters’ services.

Because of their unique capabilities, demolition robots are frequently placed in quite challenging and rigorous situations.

If attention isn’t paid to some basic preventative maintenance routines, their availability can be affected.

Always consult the manufacturer’s manuals for proper guidance and direction for the proper operation, maintenance procedures and protocols of the robot. The intention of this article is to offer focused tips and advice based on years of experience in the field in hundreds of different applications.

Used in conjunction with the recommended procedures, these suggestions should increase uptime and help users truly get the best out of demolition robots.

The single most important factor for demolition robot reliability is maintaining a clean electrical supply. For a detailed and

2 8 | J U NE .1 5

comprehensive review of electrical issues that can affect the operation of a demolition robot, please refer to the Tech Talk article published in the September 2013 issue of Concrete Openings.

Like any piece of construction equipment, a demolition robot is only as good as the pins, bushings and shafts that are in constant motion while it is in operation. If basic preventative maintenance is neglected, there can be a cascade effect which can ultimately lead to cracks in the arm system. Again, a simple daily inspection can pay enormous dividends in the life of a machine.

Start with the quick-hitch. With the machine turned on and an attachment (i.e. hammer) mounted, lift the arm slightly off the

ground, and swing it sharply to each side to check for excessive play. If there is too much movement, this could mean that the wedge holding the assembly is either too loose or that it has worn out. Either tighten it or replace it.

While demolition robots are designed to handle the forces that hydraulic hammers can generate, it is still important to maintain the three-piece boom system on a regular basis. Working up the arm from the quickhitch, check for obvious cracks in the welds, where the shafts go through the bosses and on the reinforcing plates. Also check for loose bolts, which, if left uncorrected, will eventually lead to stresses that can eventually cause cracking. A simple way to

check is to look for signs of wear where the hex head of the bolt has moved against the metal surface of the bushing. If there is space between the hex head and the metal surface, or even worse, the bolt’s thread, it is time to tighten things up—consult the operating manual for settings.

Vibrations generated by the hammer travel up the boom system and can never be entirely eliminated. The pins and shafts, plates and bosses are all designed to accommodate these vibrations, but are only effective if the bolts are tight and properly torqued. The key is to minimize any ‘slop’ in the arms. This maintains the machine’s responsiveness and efficiency.

The undercarriage is a key sub-assembly of any demolition robot and critical for the successful application of the machine in a variety of ground conditions. A daily visual inspection of the drive motor, rollers and idler to check for excessive wear, lodged debris or misalignment is a must. More important, check that the tracks are properly tensioned.

Check the owner’s manual for the correct guidelines, but veteran operators will often be able to tell by eye—by the amount of sag in the tracks—whether they are good to go.

The daily inspection should proceed in tandem with lubrication. Demolition robots come equipped with multiple grease points, and while some need daily attention and others weekly, all are important. Perhaps the most important area to address on a daily basis is the linkage where the dipper arm meets the quick hitch/attachment. This area is subject to the highest stresses and should be carefully monitored and regularly greased.

While experts would never recommend ignoring the other grease-points on the machine, they might well quietly confirm that if only one area was to be greased it should be this linkage area.

Finally, keep an eye on fluid levels. When low, the hydraulic tank should be topped up with the manufacturer’s recommended oil.

Always use the robot’s filtration system when filling the tank to prevent contaminated oil from entering the system.

There are a number of mechanical and electrical checkpoints to include in a weekly routine inspection. Start with the automatic grease levels—if they are low, either replace the cartridge or refill the canister.

Remove the side panels on the turret and check for any hydraulic oil leaks around the main valve body, pump, tank and cooler area. Occasionally, concrete or other

W WW. C O N C RE TE OPE N IN GS.COM

debris can find its way into this space. With hydraulic oil pulsing through the hoses at high pressure, chafing can occur, which if left unchecked can lead to hose failure. Look for evidence of any excess oil in the area or signs of damage to the hoses.

This is also a good time to check the radiator and clear away any accumulated dust and debris that could potentially reduce the machine’s ability to cool the hydraulic oil properly. Overheating can stop a demolition robot in its tracks, often at the most inopportune times.

After making certain that the power to the machine is turned off at its source, and the machine is unplugged and de-energized, open the electrical cabinet, check for any loose connections and ensure that all components are securely in their proper places. Next, inspect the ‘pigtail’— the short length of cable at the back of the machine that connects to the main electrical cable. Take apart the plug and make sure that the wires into the terminals are properly tightened. Check that the male prongs on the plug are in good condition.

With the demolition robot plugged back in, check the control cable—the ‘umbilical cord’ that connects the machine to the control box in the event of loss of battery power. To make sure that control cable is functioning properly, connect it to the control box, remove the battery and run through each function of the demolition robot, including arm system and undercarriage.

While demolition robots are designed to be wirelessly operated, the control cable is there primarily as a safety measure. In the event the battery in the control box runs out and there isn’t a spare to hand, the control cable can be connected and a machine that would otherwise be stranded in place can still be moved out of harm’s way. Other times, it is handy to be able to run the machine normally using the control cable when the battery runs out unexpectedly.

A demolition robot’s control box often takes a beating. As it is light and portable, the control box is sometimes treated a little too casually and can end up being tossed around. A simple test to see if there is anything wrong with a control box, is to pick it up and gently shake it. Any

suspicious rattles indicate that it is time to open it up, investigate and make sure that all components are securely in place.

Almost all demolition robots are shipped with a hydraulic breaker (or hammer) as standard. Along with crushers, buckets, grapples and shears, hammers are among the most popular attachments for these versatile machines.

Demolition robots are often used on walls and ceilings. The three-arm boom system lends itself well to applying force in the vertical and overhead configuration. One helpful tip to prolong the life of a hammer, is to fashion a ‘boot’ to provide some extra protection when hammering overhead. Take a thick rubber mat—an old tire recap works well—and use a reciprocating saw to cut it to size: a square piece that should extend only slightly beyond the lower dimension of the hammer. As an example, based on one commonly-used hammer, the square of rubber should be about 8 inches by 8 inches. Then, using a hole saw, cut a hole in the middle of about 0.125-inch less than the diameter of the point or chisel being used.

Slide the rubber mat over the chisel and

3 0 | J U NE .1 5

down the shaft to the bushing. This crude but effective shield will prevent a surprising amount of debris and even small particles of concrete from working their way into the hammer, past the seal assembly.

Another way to prolong the life of a hammer is to ensure the proper grease is used—or more accurately, chisel paste—to lubricate the point or chisel. This often neglected area may be the single most critical thing a contractor can do to prevent premature wear on a hammer. Most demolition robots come equipped with an auto-greasing function, but if the cartridge is spent or the canister empty, it might as well not be there at all. The easiest way to check to see if the greasing system is operating properly, is to look for evidence where the chisel meets the hammer. There should be a visible thin film of grease there.

If this film is absent, make sure the pump is operating or that there is sufficient grease in the system. The grease itself is also critical.

Again, follow the manufacturer’s guidelines but most will recommend an actual chisel paste. This has a much higher breakdown point than traditional grease and often

contains materials like copper and graphite.

These materials form into ‘micro-ball bearings’ as the chisel moves up and down in the housing.

More than most pieces of construction equipment, a demolition robot must cope with enormous stresses and vibrations relative to its size. Without regular preventative maintenance, these machines will succumb to those forces and suffer untimely downtime. By incorporating these simple preventive maintenance routines and other techniques, contractors can ensure they truly get the best out of these machines for many years.

INTERVENTION Cutting Contractor Lets in the Light at Megachurch

3 4 | J U NE .1 5

An electric wall saw was used to make a series of horizontal cuts, averaging 9 feet in length.

A

CSDA member recently answered the calling of a general contractor performing renovation work at a large venue in Houston, Texas. The work included the cutting, removal and hauling of three existing pre-cast panels for the addition of a curtain wall window on the fifth floor of the building. The cutting area was approximately 80 feet above a finished floor and the cut sections measured 10 feet tall, 9 feet wide and weighed 7,500 pounds each.

The job location was Lakewood Church, a 16,000-seat venue that was once home to the NBA’s Houston Rockets. The church moved into the building in 2005 and has invested over $95 million in renovation work.

W WW. C O N C RE TE OPE N IN GS.COM

The area of the building where this work was taking place had been earmarked for administrative offices, so a window opening was needed.

It was specified that the panels be saw cut, as this method would allow the surrounding parts of the pre-cast panels to remain in place for the aesthetics of the building and to preserve the structural integrity of the roof. Adjacent areas of the building were already occupied and there was a service road directly outside the building, so it was important that the window opening be created with low vibration and minimal debris to prevent damage to these areas. The general contractor, Tellepsen Builders of Houston, chose a specialist concrete cutter for the work.

“Our plan was to drill two holes in each panel for lifting so that we could take them out in whole sections using a crane. The church owners did not want the space inside the building to be exposed to the elements for a long period of time or nearby offices affected, so our work had to be fast, clean and safe,” said Chris Allen, estimator and project manager for CSDA member Aggregate Technologies, Inc. (ATI) based in Houston.

Before the work could begin, however, the roads below the work area had to be closed off from any foot or vehicle traffic. A service road, an exit lane from the church’s parking garage and an entrance to a nearby high-occupancy vehicle lane, all had to be shut down.

The team from ATI utilized a swing stage, mobile crane and other equipment to complete the work, which was done during night hours.

Due to ongoing daytime services at Lakewood Church and access requirements for Greenway Plaza, a mixed-use venue next to the church building, the crane had to set up each morning and demobilize each night of the work. In addition, limited road access and a difficult gradient meant the crane could not be positioned in front of the work area. Therefore, the crane was set up around the corner and the crane operator did not have direct sight of the panels. Accordingly, clear and accurate communication between the rigging crew and crane operator was critical to ensure the safe and efficient removal of the panels when cut.

An ATI operator used a Cardi core drill to create two holes per panel for lifting. Each hole measured 4 inches in diameter through the 6.5-inch-thick concrete wall panel and was positioned close to the top of the panels for safe rigging. With operators positioned on the outside and inside of the building, straps were run through the two core holes to secure the panel to the crane. This would help restrict the panel’s movements while cutting and ensure the cut section did not break away from the building prematurely.

The first cutting task was to remove the waterproofing material between the first panel section and the adjacent section that was to remain using specialized sawing equipment with a metal cutting blade. An operator then set up a Pentruder electric wall saw fitted with a diamond blade from Husqvarna to perform a 9-foot horizontal cut.

Cut sections were rigged and removed by crane to the floor below.

Lakewood Church The church was established in 1959 and moved into its first permanent home, an abandoned feed store, that same year. In the decades that followed, the church grew exponentially under the leadership of Pastor John Osteen and moved to different buildings to accommodate larger congregations. During the 1980s, Lakewood Church also began a television broadcast to the Houston area.

John Osteen passed away in 1999 and his son, Joel, became pastor.

The church continued to grow and in 2005, Joel moved Lakewood Church into its present location, the former Compaq Center, a 16,000seat arena that was once home to the Houston Rockets professional basketball team.

Today, Joel and his wife, Victoria, lead what has become known as a “megachurch” and are household names in the U.S. and beyond.

Each week, Joel preaches to more than 38,000 attendees and his weekly sermon is broadcast into every U.S. television market. It is viewed by seven million Americans each week and his weekly broadcast is seen in almost 100 nations around the world.

“My main concern was removing only a portion of the pre-cast concrete wall and wondering what would hold the remaining portion in place. Fortunately, a structural engineer designed the plan to remove the panel sections and confirmed the sections that were to remain would be structurally sound,” said Allen. “The roadways below the panels were an issue too, as there was no way to reach the work area with any ground lifts due to the slope of the road and the height required. We had to use a swing stage from the roof to access the exterior of the panels.”

This presented further issues to Allen and his team, as there were now more obstacles for the crane operator to work around—the cable of the swing stage, the safety lines of the workers on the swing stage and the presence of workers right next to the cut section while it was being removed. Before work started, each worker and the company’s safety director had to check safety harnesses, lift lines and anchor points for damage. The project was completed with no safety incidents and ahead of schedule.

“The original schedule assumed three nights to complete, but due to ATI’s careful selection of experienced staff, coordination and pre-planning, the contractor was able to safely complete its work midway through the second night. I would like to personally congratulate ATI for being an integral subcontractor in the successful completion of the central fifth floor office renovation at Lakewood Church,” said Martin Jasinski, project manager for Tellepsen Builders.

As a result of this job, ATI anticipates further work from the general contractor. The renovation of Lakewood Church’s administrative offices continued as planned and staff now ‘see the light’ thanks to the concrete cutting work performed by this CSDA member.

The three pre-cast panel sections weighed around 7,500 pounds each and were broken into smaller pieces before being hauled from site.

This separated the top of the specified cut section from the rest of the panel. Another 9-foot horizontal cut was made 10 feet down the wall, parallel to the first. These cuts each took around five minutes to complete through the 6.5-inch-thick concrete, including setup and take down.

At this stage, the only supports holding the panel in place were two metal weld tabs on the bottom of the panel and the crane. An operator was positioned outside the building on a swing stage, communicating with the crane operator by radio. It was their job to confirm all parties were ready to begin lifting the panel before cutting the metal tabs loose. ATI cut the two metal tabs and began to tilt the cut panel section out of place, then it was lifted out by the crane. Once the panel was on the ground, the cutting contractor used a Husqvarna slab saw to cut the panel into smaller, more manageable pieces. These pieces were lifted onto the company’s dump truck to be hauled from site.

ATI repeated this process for two more panel sections of similar sizes and the work was completed in approximately one-and-a-half shifts—around half the time originally allocated for the work. The cutting contractor performed around 30 feet of 6.5-inch-deep wall saw cuts, created six 4-inch-diameter rigging holes and used a slab saw on the ground to split the panels in half for hauling.

Safety Counts

Hazard Communication Standard Enforcement Underway

By Mark A. Lies II and Patrick D. Joyce

A

re you ready for the new Safety Data Sheet (SDS) requirements?

Failure to properly provide or respond to new SDS information could open the door to an OSHA inspection and enforcement activities, including citations and significant penalties for violating the Hazard Communication Standard 2012 (HCS 2012) (29 CFR 1910.1200).

OSHA adopted new HCS 2012 SDS standards on December 1, 2013. The new standards were implemented to harmonize material safety information with the new Globally Harmonized System (GHS), created by the United Nations to ensure uniformity in communicating information about hazardous materials across the globe.

June 1, 2015 represented a major enforcement deadline of the new standard: manufacturers must now stop sending the old Material Safety Data Sheets (MSDS) and send the new SDS instead. Chemical end users have until June 1, 2016 to respond to new SDSs passed down from up-stream suppliers and manufacturers in the workplace. This one year period presents a very short time frame in which an employer can respond to the new and updated information contained on potentially hundreds of SDSs and be complaint by June 1, 2016.

SDS IMPACT ON EMPLOYER SAFETY PROGRAM Employers should not be too quick to simply swap in a new SDS for an old MSDS and throw away the old MSDS. Previous MSDSs should be kept on file for several reasons: • To provide proof that an employer was compliant with the old HazCom standard.

• The prior MSDSs can be useful evidence in defending against Worker’s Compensation claims by employees for occupational diseases alleged to have arisen from exposure to hazardous materials during the course of employment.

3 8 | J U NE .1 5

•

The prior MSDS can be useful evidence in defending third party toxic tort claims alleged to have been caused by exposure to hazardous materials that the employer may have incorporated into products manufactured and sold by the employer, or by products that are resold or distributed by the employer.

The new SDS presents an opportunity for an employer to update its training, hazard communication and safety procedures for chemicals. The new SDS includes sixteen separate sections, some of which are similar or identical to the existing MSDS sections.

There are, however, a number of significant changes and compliance challenges. These sections will be discussed below with recommendations.

Now that enforcement in underway, OSHA will not only be looking to see that a manufacturer has properly prepared new SDSs, they will also be looking to make sure the manufacturer went through a process to identify new risks that may not have previously been known. When OSHA begins enforcement against employers on June 1, 2016 relating to the new SDSs, it will focus on whether the employee has reviewed the SDSs to identify any new risks as well as whether it has evaluated its existing compliance programs in light of the sixteen requirements in the new SDSs. NEW SDS SECTIONS—QUESTIONS AN EMPLOYER SHOULD ASK Below are brief descriptions of each section of the new SDS, as well as some questions an employer should consider to ensure employees are provided a safe place to work, that it will be compliant with its Haz Com program as well as other OSHA

The Business of Business

Online Crime Affects More Than You May Think

By Kristen Long

I

n the September 2014 issue of Concrete Openings, I wrote an article titled “The Threat Posed by Cyber Criminals.” In the article, I discussed the emerging risk of cyber crime and the link between Main Street American businesses and the Fortune 500 company attacks. Now is the time to revisit this topic, because since that time, cyber criminals have elevated their game and continue to carry out malicious attacks on American businesses and individuals through phishing emails and malware viruses. Several large data breach events have taken place in the mere five months since I last addressed the issue. JP Morgan Chase, Staples, Sony, Michael’s, Home Depot, Albertson’s, Kmart and Dairy Queen have all fallen victim to cyber criminals. Even last month we witnessed possibly the most devastating breach to date—the attack on a health insurance giant, Anthem Inc. As the level of sophistication and number of attacks continue to increase, it can be overwhelming to attempt to protect your household or your business. In the following article, I am going to share some basic information and tips to help equip you in the fight against cyber perils.

CYBER-ATTACKS ON THE HOUSEHOLD The breach on Anthem Inc., the second-largest health insurer in the U.S., compromised the information of over 80 million people, or 1 in 4 people, in the United States. The attack included spouses, dependents (such as children) and even deceased family members. The information stolen included the following: Social Security numbers, dates of birth, addresses, names, phone numbers, email addresses and even salary information. Having all of this confidential personal information is like giving a criminal or outsider a passkey into your life.

What is concerning, is the lack of outcry from the public. Hundreds of millions of people have been affected by the data breaches over the past year and yet there

4 2 | J U NE .1 5

remains no urgency to fend off the hackers.

Why is that? Up until now, data breaches have mostly affected credit cards. Credit card companies have provided fraud protection, paying out of their corporate pockets any expenses/damages and replacing credit cards when customers’ information has been compromised. While the attacks reached a huge number of people, the outcome for most individuals was a minor annoyance rather than a crippling event. Now, imagine instead of merely needing to update your Netflix payment method, you discover that your

credit rating has been damaged, your Social Security number was used by another person to obtain employment or you are now unable to receive healthcare when needed. To take it one step further, what if somebody stole your child’s identity? That is a very real possibility and touches on the magnitude of medical and Social Security identity theft.

Monitoring and correcting medical or Social Security identity theft can be a difficult and time-consuming task. Since this is a new breed of attack, we are just learning the power of these crimes and it could take years or even decades to understand the

true enormity of the events. Below are the definitions and details of medical and Social Security identity theft: • Medical Identity Theft occurs when someone steals your personal information (like your name, Social Security number or Medicare number) to obtain medical care, buy drugs or submit fake billings to Medicare in your name. The Coalition against Insurance Fraud offered the following warning regarding medical identity theft, “But be warned: Correcting records can be hard. In general, federal law lets patients’ correct medical records created only by the medical provider or insurer that now maintains your information. A hospital or insurer that later receives your information doesn’t have to correct its records—even when they’re wrong. But you do have the right to have your records state that you disagree with the information, and why. Be sure your complaint is entered into your records”.

• Social Security Identity Theft involves fraudulently using someone’s Social Security number (SSN) to get a job, file for governmental benefits, fraudulent tax returns, credit and medical care.

The Social Security Administration says, “If you have done all you can to fix the problems resulting from misuse of your Social Security number and someone still is using your number, we may assign you a new number”.

According to the Identity Theft Assistance Center (ITAC), “Adults can monitor their own credit reports every few months to see if someone has misused their information, and order a fraud alert or freeze on their credit files to stymie further misuse.

But most parents and guardians don’t expect their youngster to have a credit file, and, as a result, rarely request a child’s credit report, let alone review it for accuracy. A thief who steals a child’s information may use it for many years before the crime is discovered.

The victim may learn about the theft years later, when applying for a loan, apartment or job”. Further the ITAC states, “until recently, very little was known about the scope of the crime and how the stolen information is used.

ITAC sponsored the 2012 Child Identity Fraud Report to get verifiable data that can be used to develop solutions to identity theft.” Prior to the current string of data breaches, ITAC conducted a study into child identity theft, below are the key findings.

The Business of Business 2012 CHILD IDENTITY THEFT KEY FINDINGS •

Social Security numbers are the most commonly used piece of information by identity thieves targeting children. In fact, 56% of respondents reported theft or misuse of a child’s SSN. • The most common way criminals use a child’s personal information is to combine a child’s SSN with a different date of birth to create a new identity that can be used to commit fraud. Fraud involving “synthetic identity” is especially difficult for victims and industry to detect.

• The study found that 2.5% of U.S. households with children under age 18 experienced child identity fraud at some point during their child’s lifetime.

This equates to one in 40 households with minor children being affected by this crime.

• Fraud committed by family and friends is to blame in many child ID theft cases.

The data shows that 27% of respondents reported knowing the individual responsible for the crime.

• Low-income households are disproportionately affected by child identity theft. As family income decreases, the risk of child identity fraud increases. While 50% of households of child identity theft victims had incomes under $35,000, only 10% of households of child identity theft victims had incomes of more than $100,000.

• Child identity theft is more difficult to detect and resolve than adult identity theft.

The survey showed that these crimes took 334 days to detect, 44 hours to resolve and 17% of children were victimized for a year or longer.

If these data breaches have taught us anything, it is that every American household, child and business should be taking, at a minimum, the following steps to monitor their identity: 1. Credit Monitoring / Freezing – Sign up for monitoring with all credit bureaus directly or via a credit monitoring company.

Remember to include children.

2. Child Identity Protection http://www.consumer.ftc.gov/ articles/0040-child-identity-theft 3. Medical Identity Monitoring – Review your health insurer’s monthly and annual report of charges.

online has risks and rewards. As adults, we must reduce the risks by talking to kids about making safe and responsible decisions. SafeKids.com (http://www. safekids.com/safety-advice-tools/) offers many suggestions on areas of discussion with your children.

CYBER-ATTACKS ON YOUR BUSINESSES My previous article highlighted the potential for smaller businesses to become a gateway to much larger companies. As discussed, the massive Target attack in late 2013 was a perfect example of how cyber criminals hone in on small businesses to gain access points to larger prey. In that instance, hackers penetrated an HVAC contractor in Pittsburgh that performed contracting work for a local Target. Once the hackers had taken control of the HVAC contractor’s systems, the thieves discovered an online portal that Target used for its vendors for payment and contract delivery. That was all the hackers needed to hit the mother-load.

So, how many larger companies do you do business with? Large general contractors, banks, owners, suppliers, etc. could all be targets and you could unknowingly serve them up on a platter. Does your company execute vendor contracts that allocate liability and indemnification for data breaches? When protecting cyber risks, companies often ignore the risks created by their vendor agreements. Your business partners create exposures outside of your internal IT business network. Cyber breaches involving a third party muddy the waters and spill into complex litigation.

As a first line of defense, every company should establish training and a risk management program for its cyber exposure, including remote access, cell phones, laptops and even tablets. This should include a response plan in the event your company is hacked. Who will you call first? Your company IT professional should be included as a strategic partner to help guide your plan and company training.

Equally important, is the purchasing of Cyber Liability Insurance. Cyber insurance is an continuously developing product that can cover both liability and property damage losses that may result from a business engaging in various electronic activities, such as selling on the Internet or collecting data within its internal electronic network (such as payments from clients via credit cards). Cyber insurance policies can cover

a business’ liability for a data breach in which customer information, such as Social Security or credit card numbers, are stolen by a hacker who has gained access to the firm’s electronic network. The policy would cover a variety of expenses associated with data breaches including: notification costs, credit monitoring, costs to defend claims by state regulators, fines and penalties and losses resulting from identity theft.

Currently, there is a market for cyber liability insurance, but as the amount of attacks have increased, insurance carriers have tightened up their underwriting guidelines before accepting new policyholders. The insurer will need verification that the company is up to date on firewalls, antivirus, antimalware and if it monitors how access is granted to company systems. So, please be aware that bringing you “up to code” in terms of insurability and finding the proper market for your company may require time and effort.

When considering the probability of whether you or your company will suffer a cyber attack, it is no longer a question of “if,” but “when”. As cyber crime continues to progress and the stakes become more severe, it is our responsibility as heads of households and professionals to educate ourselves as to how to best defend our own information as well as others. Kaspersky, Internet Security Company, has an excellent training tool called the “Stop Cyber Crime Guide.”

As an insurance professional who specializes in the construction industry, and a victim of identity theft, it troubles me to say that less than five percent of my clients have implemented the security procedures discussed above. I implore each of you to take this issue seriously and to be proactive in protecting your personal, business and client’s information. While the thought and expense of putting a security plan into action may seem daunting, it is a fraction of what you will be forced to deal with if you are attacked without one.

Polished Perspective

The Architect’s Viewpoint: Specifying the Right Floor—Part IV

By Andy Bowman This is the final installment of this four-part article. Parts I to III were published in the three previous issues of Concrete Openings and focused on the selection and preparation of the appropriate flooring system. Please refer to these issues or visit www. concreteopenings.com to view online.

FLOOR SYSTEM TROUBLESHOOTING Fish Eyes They occur due to a difference in surface tension between the coating and the substrate. This can be the result of a contaminant (oil, grease, dust, sealers, etc.), amine blush, primer outside the recoat window, moisture, etc. In most cases, good surface preparation will solve the problem. To verify if the problem is substrate or product related, mix a small amount of the material and apply to a sealed surface outside of the project environment. If this does not “fish eye,” you know the problem is on the substrate. If this also fish eyes, stop coating and call your product supplier.

To stop fish eyes, you can add 1-2 pounds of 325 mesh silica flour, per mixed gallon of pigmented epoxy. The silica flour can only be mixed in (dispersed) with a drill mixer. This can slightly change the color so be consistent. This is not a substitute for proper surface preparation. Do not add silica flour into a clear epoxy topcoat, as it will cloud or opaque the coating.

Air Bubbles Air bubbles come from a variety of factors. Typically, if the problem is in the material, bubbles will occur uniformly and within 30 minutes of application. This can be the result of the product, temperature, mixing or application technique.

Check substrate and product temperature. The thicker the film and lower the temperature, the more difficult it is for the resin to release air. The addition of silica flour,

4 6 | J U NE .1 5

as mentioned above for fish eyes, will stop air bubbles if they are product or mixing related.

Have an air release additive on hand for all coating application, as a precaution.

Substrate out-gassing is difficult to predict or anticipate. Priming or coating late in the day, as the slab temperature is falling, is a good practice. These bubbles occur late in the cure, often after the contractor has gone.

The product is no longer fluid and will not flow back to close the hole. They appear as small craters, with raised edges. To repair, they must be sanded smooth and the hole filled prior to coating or they will reappear.

Amine Blush This phenomenon is common. The name refers to the curing agent/ hardener, which is an amine. It can and will react with moisture and carbon dioxide in the air to form the blush. Dependent upon the formulation, it is most likely to occur at low temperatures or high humidity and is worse when in combination. Many novolac epoxies will blush in ideal conditions. The blush should be visible as a film or haze on the surface that reduces gloss. It is noticeable by touch. It can be removed by a warm water detergent scrub, solvent or mechanical abrasion (sanding).

A blush can also be an indication of improper mix ratio or an incomplete mixing.

Color Change/Pigment Float Epoxies by chemistry are not color stable. If you do a project in phases, with the same batch number of material, you can anticipate a slight shade differential at the tie-in. Use only one batch number of topcoat, if you have more than one batch number, box the material.

Plan your project to minimize the time between mix-to-mix tie-ins. This is formulation and temperature dependent but a good rule is: try not to go beyond 20 minutes.

Do not roll into a partially cured edge. Use joints or other natural breaks to minimize the time between mixes. If you cut-in too far out in front, you will need to re-roll over this material to avoid a shade differential.

Special color requests are more likely to have a pigment flotation issue than standard colors. It can be more pronounced in dark/ deep blues, browns and greens.

SPECIALTY TOOLS Having the flooring system installation tools will minimize problems and the need to possibly redo a job.

• Spiked shoes – Those back rolling will need to walk in wet material.

• Silica flour.

• Loop rollers – For self-leveling coating applications of more than 12-15 milliliters (0.5 to 0.6 inch). They leave no roller fuzz nor do they impart air. If utilized in a thin film, they will leave texture.

• Porcupine rollers – To remove air bubbles, while the material is still wet.

• Mil gauges – To insure thickness and coverage rates.

• Infrared thermometer – Do not leave home without it.

• Dew point/humidity meter (psychrometer) • Air release additive.

• Adhesive roller covers are great to back roll with but can be hard to find. Some Home Depot and Sherwin-Williams

CSU-201502-Concrete Open Isl Half_Layout 1 1/15/15 4:28 PM Page 1

stores do carry them. They shed almost no roller fuzz/lint. They should only be used to back roll as they hold little material and must be kept full to avoid whipping air into the coating.

ONGOING MAINTENANCE AND PROTECTION OF THE FLOORING SYSTEM Seamless floors are based upon a chemical reaction, which converts the fluidapplied flooring material into a strong and durable solid floor. Just as in the chemistry lab or in the kitchen, the chemical reaction will be affected by temperature, moisture and other contaminants. Therefore, throughout the curing process and before placing the floor into service, the flooring system must be protected from both environmental and physical damage.

Immediately after application, it is important to keep traffic and debris off the surface until the coating is fully cured (18 – 24 hours at 77 degrees Fahrenheit), unless otherwise stated by the manufacturer.

Allow the resinous flooring system to cure for 24 – 48 hours prior to covering to protect from damage and wear during the construction operation.

Cover flooring with a breathable material such as cardboard, carpet padding or Kraft paper. Do not cover with plastic.

Cover this breathable material with 6-millimeter (0.25-inch) thick hardboard, drywall, plywood or particleboard. Tape edges to prevent movement in areas where foot or vehicle traffic, rolling of fixed scaffolding and overhead work occurs.

Do not allow the protection of the underlying finished flooring system to be exposed to water or other moisture during the construction period.

Healthy Eating on a Budget

By Erin O’Brien

M

ost of us are well aware of the benefits of a healthy diet – and those who are trying to eat healthier have likely noticed that the grocery bill tends to run a little higher when purchasing healthy, all-natural and organic foods. While we know that there are long-term benefits to this healthy lifestyle, our budgets can restrict the amount of organic, all-natural and healthy food we purchase. By shopping a little smarter, we can stretch our dollars further and still enjoy delicious foods and the positive health benefits they provide.

The following are some of the healthy foods that give you the most bang for your buck.

Potatoes ($0.99/pound) Potatoes come in a variety of colors (white, red, purple and orange) and each type of potato has its own mix of nutrients, so variety is important. They all contain high levels of potassium (proven to be essential for health heart function) and Vitamin C, which is important to keep our immune systems functioning properly. If possible, keep the skin on – 20% of the nutrients are found in the skin, but so is most of the fiber.

Potatoes also contain a “resistant starch”

which has been shown to help stabilize blood sugar levels.

Canned Pumpkin ($1.29/can) Low in calories and high in fiber and Vitamin A, canned pumpkin has the additional benefit of having a long shelf life.

Not just for Thanksgiving, it can be used in sweet and savory dishes like breads, cookies, oatmeal, yogurt, pancakes, smoothies and stews. Pumpkin also aids in digestion and boosts immunity.

Bananas ($0.79/pound) The perfect portable snack, bananas can also be peeled and frozen for use in smoothies instead of ice. They are high in potassium and fiber, with about three grams of fiber per serving.

Popcorn ($1.00/pound) Put those microwave popcorn bags away! Besides being full of potentially harmful chemicals, they also contain a high amount of calories from the flavorings.

Instead, take a few more minutes to air-pop plain kernels on the stovetop. One cup of popped popcorn has only 30 calories. For

a richer taste, pop it in coconut or olive oil and flavor with sea salt, parmesan cheese, cinnamon, herbs or spices. A little bit of grass-fed butter works well here too.

Peanut Butter ($2.79/jar) A study in the Journal of the American Medical Association Internal Medicine found a link between peanuts and a lower risk of cardiovascular disease. This is due to the mono- and polyunsaturated fats in regular peanut butter (not the reduced-fat or fat-free kinds, avoid those). Be sure to eat peanut butter in smaller portions due to its dense caloric content. Two tablespoons contains eight grams of protein but about 200 calories.

Olive Oil ($8.33/liter) A diet including olive oil can help reverse metabolic disease syndrome, according to a study by the Canadian Medical Association Journal. Olive oil also supports bone health, lowers the risk of cardiovascular disease and improves brain cell function. Best when consumed cold in dressings and vinaigrettes, it can also be used to cook at low to medium temperatures. At only twelve cents per

tablespoon, this versatile ingredient will go a long way in improving your health.

Frozen Broccoli ($1.69/pound) Frozen fruits and vegetables are frozen at their nutritional peaks, so the vitamins and antioxidants are retained until you are ready to eat. Broccoli holds up well to freezing and helps to reduce inflammation, decrease your cancer risk and detox your body.

866-688-1032 DIAMOND TOOLS & EQUIPMENT

Regular Rolled Oats ($1.00/pound) Be sure to go for the plain, not flavored varieties here. Flavorings add processed sugars and fats. Rolled oats are high in soluble fiber, which slows digestion and keeps your full longer. A half cup contains five grams of fiber and about 150 calories.

Add a sliced banana, cinnamon or honey for some sweetness.

Raw Pumpkin Seeds ($6.00/pound) Also known as pepitas, these seeds can be consumed in small quantities for great health benefits. One ounce contains over eight grams of protein, they are high in iron, potassium, phosphorus, magnesium and zinc, which plays an important role in maintaining immunity. Add to salads, yogurt and oatmeal or enjoy them by themselves as a snack.

The foods mentioned above are nutritious and versatile, and should be a part of every healthy-eater’s diet. Additionally, most of them can be bought in bulk which ensures a constant supply of economical, healthy foods and can lower the price on these foods even more. They store for long periods of time, or can be prepped to be stored with minimal work. You no longer can make the excuse that eating healthy is too expensive! Stock up on these items the next time you are in the grocery store and enjoy all of the benefits they have to offer.

Aggregate Technologies, Inc. Wins Safety Excellence Award

Bosch HD18-2 Two-Speed Hammer Drill The 120-volt Bosch HD18-2 two-speed hammer drill has an 8.5-amp motor and offers high torque and high speed to meet a range of applications in concrete, masonry, wood and metal. First gear is for high-torque applications, including maximum diameter drilling; second speed is for high-speed drilling. The dual-mode selector converts from hammer drill to rotation-only mode and an integral slip clutch disengages torque transmission if the bit gets into a bind situation. The HD18-2’s impact mode allows the tool to be used for drilling into brick and block and, depending on the hole diameter and drilling depth, this setting can be used in some concrete applications. First gear (or slow speed) allows the tool to be used with hole saws/spade bits in wood, standard bits/metal hole saws in metal and masonry bits/carbide-tipped hole saws in brick/ block. First-gear accessory capacities range from 0.75 inch for concrete/masonry applications and 0.5 inch for metal jobs to 1.56 inches for wood. A rotating brush plate provides equal power in reverse to back out bound-up bits, while a metal gear housing provides jobsite durability. The drill’s auxiliary handle offers increased torque control and can be securely locked into place.

CSDA member Aggregate Technologies, Inc. (ATI) of Houston, Texas, was named one of the nation’s safest construction companies of 2014 as part of the Willis Construction Safety Excellence Awards (CSEA), an annual ranking of construction safety programs compiled by the Associated General Contractors of America. Thirty-seven firms were named winners, with ATI selected first place in the Specialty Division’s 100,000–300,000 Work Hour Category for exceptional leadership in safety. ATI submitted an application in December 2014 along with over 300 other applicants nationally. A panel of judges narrowed this list down to 38 applicants in five different categories. As a finalist, ATI owner Ronnie Wills and safety director Rhonda Mitchell were required to make a five minute presentation about the ATI Safety Program and their work to a panel of five judges. The winners were announced earlier this year at the annual Willis Safety Awards Breakfast in San Juan, Puerto Rico.

Bosch D-tect 120 Detector The Bosch D-tect 120 features Spot Detection technology that can detect objects up to 4.75 inches deep when placed on a wall or floor.

It can detect objects directly below it and indicate the direction of nearby objects using arrows. Electronic “traffic light” indicators make detection straightforward and simple to understand: Green, nothing detected; orange, something is close; red, object detected. The unit does not require calibration and is ready to be used the instant it is switched on. The Bosch D-tect 120 can be used in a variety of applications in three modes: drywall, universal and concrete. It offers sound as well as light to alert the user when something is detected behind a wall, a panel or under flooring. The D-Tect 120’s universal mode can be used when the wall material is unknown or consists of multiple layers of different materials while the concrete mode is optimized for concrete and similar materials; its primary use is to search for rebar. Other features of the Bosch D-tect 120 include an unshielded AC warning to avoid drilling into live wires and a center finder to indicate an object’s center.

D-Drill, which employs 100 staff nationwide, is also set to invest in training, machinery and marketing as it bids to expand during 2015/16. “The new vans and their designs are quite eye-catching.

This networking provides opportunities to forge new relationships and learn from other experienced professionals.

NEXT GEN

CSDA NEXT GENERATION GROUP The group aims to continue the growth of the association while serving the needs and wants of the younger generation, with the goal of continuing to set a standard of excellence.

TESTIMONIAL I have been diamond wire sawing for 32 years. It was two decades ago that the association’s executive director, Pat O’Brien, encouraged me to attend a quarterly CSDA meeting and see what the Board and committees were doing for the industry. Once there, I was charmed by the people and intrigued by the review of technical and safety topics. It was also the beginning of life-long friendships with owners and key suppliers in the diamond cutting industry, almost all of which remain strong today. Back then I thought I knew it all.

“What are these people going to show me?”

Well, 20 years later I am still learning from my contractor and supplier friends. I continue to discover new ways to Tim Beckman perform better and safer, Cutting Edge Services Corporation Batavia, Ohio simply by talking with beckman@cuttingedgeservices.com my peers, and enjoy the comradery and good times along the way. For me, this is true value and why I remain a member of the association.

Director’s Dialogue

CSDA Angels

PATRICK O’BRIEN Executive Director

A

ngel investors are a special class of business people that help finance and cultivate small start-up companies. CSDA also has angels to help advance the association and the industry.

As executive director for the past 20 years, I have worked with many CSDA Angels and would like to recognize these people, because we would not be where we are without their tireless efforts. The CSDA Angels in this case are the Officers, Board and committee members who have served the association.

No one individual or group could have achieved the success CSDA has earned, but the combined efforts of so many have made a fantastic difference. Perhaps the most visible to members are the Officers and Board of Directors who are elected by members. These dedicated leaders contribute so much over several years to make the association the best it can be. Before being elected, a member serves on one or more committees, often acting as a committee chair, for at least one or two years. After election, they continue to serve on the committees for a one- or two-year term as a Board member before being elected as an Officer. If this member continues and becomes President, they will serve for an average of 10-12 years and the same applies to the roles of Vice President, Secretary/Treasurer and Past President. This is quite a commitment!

Committee members are another key group and form the backbone of the association by accomplishing many projects that

6 4 | J U NE .1 5

advance the association and industry. These members meet in small groups and volunteer their time and talent to complete numerous projects that ultimately benefit CSDA members. They pay for their own travel to the quarterly meetings and often work between meetings to complete their committee projects. CSDA could not offer so much to members if it were not for these dedicated folk.

The CSDA staff work with the Board, Officers and committee members to help turn ideas into results. They provide the consistency from one generation of Board and committee members to the next and help keep the many programs moving forward. But the staff cannot do it alone, and it requires the dedication of everyone to create more success stories for CSDA. CSDA Board and committee meetings are held quarterly. These two-day meeting schedules are held in different cities across North America, giving local members the opportunity to attend, learn and network with fellow members. But more importantly, the committees need to hear from members as to what is important and what needs to be done to help advance CSDA’s interests and that of the industry.

Members and prospects have an open invitation to attend any Board and committee meeting and attendance is encouraged. The meetings for the upcoming year are listed in the calendar on page 60.

Who knows, you might decide that you want to become a CSDA Angel and help define the future of the association.

I look forward to welcoming you to a future meeting.

Everything you need in one package.

Husqvarna's WS 220 is the perfect all-in-one high

frequency wall saw with high power and deep cutting. It's unbeatably efficient for smaller/mid-sized jobs with a cutting depth of up to 15" (390 mm). The saw is easy to use, and the saw head delivers a full 8 hp (6 kW) on the shaft, but weighs

only 42 lbs (19 kg). It's so flexible that you can even run it on 1-phase power, if needed. All of this comes in an extremely easy to maneuver package thanks to the included trolley.
