KEVIN BARON CSDA President

his year we will witness what is being hailed by some as the most important U.S. presidential election in a long time. There is a lot of individual trepidation about the outcome and how the political landscape may change. For me, the focus should be on the opportunities that are before our industry right now and the positive signs that are being shown around the country and the world. I traveled to Las Vegas last month for the annual World of Concrete trade show and exhibition and there were many positive signs around the show. Organizers had already confirmed it was the largest show in seven years in terms of exhibit space and we now know that attendance hit the 60,000 mark. Exhibitors had lots of traffic and attendees had a lot of new and innovative products to explore. The general trend is that if things look good at World of Concrete, the industry should have a strong year. CSDA had a fantastic WOC too. The association’s booth had lots of traffic, training classes were full, the Concrete Openings Awards ceremony was very well attended and the Next Gen reception was a big success. An excellent show for CSDA. A special thanks to our instructors Lee Aitken, Rick Norland, Pat Stepanski and Chris Swanson—outstanding job, gentlemen. In addition, the passing of the new FAST Act (Fixing America’s Surface Transportation Act) highway bill should open up a huge amount of work on the nation’s roadways. The new Act is fully funded for five years and will grow 15.1 percent annually ($40.3 billion to $46.4 billion by 2020). So for those in the industry that are

involved in highway cutting, grooving and grinding work this is great news. For those not currently doing this type of work, there may be scope to get a piece of the action. Having spoken with many CSDA members involved in other types of concrete cutting, polishing and GPR imaging work, however, things are looking up across the board. Contractors are upbeat and finding that their workloads are increasing as more construction and renovation work is being approved. For many, the challenge now is finding qualified or experienced employees to help do the work. This is where CSDA membership can be a huge benefit. Since 1972, the association has focused not only on promoting specialist contractors and their methods to architects, engineers, general contractors and government officials, but also on the establishment of safety documents, training programs and other resources to help contractors complete work safely, efficiently and ultimately increase their bottom line. CSDA is already seeing an increase in membership applications and training class participation as signs of economic recovery continue. The association graduated 115 professionals from its four World of Concrete training classes—a significant increase from last year. The value of sending employees to industry-focused training courses is being realized by a growing number of people. CSDA is for the concrete cutting, polishing and GPR imaging industry. It always has been, and always will be. As workloads increase and more opportunities come along, I encourage you to take a closer look at what the association has to offer and how its resources can assist employers and employees alike.

The contractor cored drilled holes measuring 18 inches in diameter through concrete pipe piles.

ne CSDA member recently traveled to Naval Station Guantanamo Bay to cut and remove an old concrete pier and returned several months later to resolve a critical issue with the new pier construction. The job involved core drilling six 18-inch-diameter, 7.3-foot-deep holes in concrete pipe piles using diamond tools.

Concrete Cutter Repairs Pier at Guantanamo Bay Naval Station Naval Station Guantanamo Bay, Cuba (also known by the designation code GTMO and pronounced â&#x20AC;&#x153;gitmoâ&#x20AC;? by the U.S. military) is on the front lines for regional security in the Caribbean area. The base supports the ability of U.S. Navy and Coast Guard ships, along with allied nation ships to operate in the Caribbean area by providing contingency and quality logistical support with superior services and facilities. The base also supports the Department of Homeland Security in U.S. migrant operations to help care for displaced migrants from the surrounding area, effectively helping control the flow of illegal immigrants into the United States. The Tampa, Florida office of Orion Marine Construction was contracted by URS Group/RQ Construction to remove an old pier at GTMO and construct a new one in its place. The pier replacement is part of a larger project URS/RQ is performing at the base. To avoid compromising the security of this location, no further details on the scope of the overall project have been authorized by the U.S. Navy.

Operators used 8-foot-long core bit to drill 7.3-feet deep.

In October 2014, Accu-Cut Concrete Services, Inc. of Clearwater, Florida, performed cutting techniques with diamond tools to remove the old pier at the base. The work involved flat sawing the main wharf deck, which was cut and removed in sections by crane. The contractor also used a wire saw to cut the main wharf pile caps into sections, making cross sectional cuts through the caps to leave them standing free on the piles. All piles under the caps were cut to different elevations using Accu-Cut’s patented Stingray pile saw. The diamond wire sawing system intergrated into the Stingray, named because of its shape and use in the water, allows it to be positioned around piles and perform clean pull cuts. This customengineered saw has previously featured in the Concrete Openings stories Bayway To Go! and Semper Paratus (Always Ready) [December 2013 and 2014 issues respectively]. This phase of work was completed in January 2015 and the new construction began shortly after. It was six months later, in July 2015, when Accu-Cut was asked to return to GTMO. The construction of the new pier was well under way when the general contractor encountered an issue with several of the pipe piles. After all the new large steel pipe piles had been driven, the concrete caps had been placed and as the deck panels and rebar were being placed, it was discovered that more than ten #11 steel bars would need to be added to six piles to consider each of them structurally stable. The piles already had a cage of #11 rebar and had been filled with concrete to the top, through the pile cap. Mark Valenti, Professional Engineer and project manager for Orion Marine Construction, contacted Accu-Cut owner John Robinson to discuss several options that would resolve the issue. “We discussed the possibility of removing all the concrete from the top 15 feet of the pipe piles or core drilling individual holes for each of the #11 bars. Other options were considered, but ultimately the engineers approved a plan to core an 18-inch-diameter hole 7.3 feet deep into each pile. The core was then to be broken off and removed. The inside surface of the hole was roughened before the additional cage of #11 rebar was installed and the opening filled with concrete,” Robinson explained. Core drilling techniques were specified because it was the least destructive method available for the newly-constructed piles and caps. The low vibration produced by cutting with diamond core bits preserved the integrity of the concrete, while the precision of the cuts provided the general contractor with cores that were easy to remove from the piles.

U.S. Naval Base Guantanamo Bay is the oldest U.S. base overseas and the only one in a Communist country. Located on the southeast corner of Cuba, the base is about 400 air miles from Miami, Florida. In December 1903, the United States leased the 45 square miles of land and water for use as a coaling station. A treaty reaffirmed the lease in 1934 granting Cuba and her trading partners free access through the bay, payment of $2,000 in gold per year, equating to $4,085 today, and a requirement that both the U.S. and Cuba must mutually consent to terminate the lease. The base is divided into two distinct areas by the 2.5-mile-wide bay. The airfield is located on the Leeward side and the main base is on the Windward side. Ferry service provides transportation across the bay. The primary mission of Guantanamo Bay is to serve as a strategic logistics base for the Navy’s Atlantic Fleet and to support counter drug operations in the Caribbean.

The holes were filled with additional steel rebar and concrete.

Once the method was established and the engineering approved, Accu-Cut was given notice to proceed in August 2015 and was instructed to expedite the process wherever possible. The contractor contacted Welco Diamond Tool Corp. to engineer a matched set of 18-inch-diameter core bits 28, 48 and 96 inches long. In turn, the manufacturer reached out to CSDA member Western Saw, Inc., to make the specialty tubes for the bits. Western Saw made the barrels complete with welded tops and 1.257-inch hex nuts ready for Welco to place the diamond segments. The core bits were completed and picked up by the contractor one week after placing the order. While the core bits were being manufactured, Accu-Cut fabricated a 6-foot aluminum drill column with a removable 4-foot extension. This gave the contractor the ability to have a 10-foot column in case the core drill operator had to back the 8-foot-long bit completely out of the hole while keeping it mounted to the hydraulic spindle. All tools, equipment and spare parts were shipped to site on the GTMO supply barge. This was the only means of shipping available to Accu-Cut for materials, as no commercial courier services deliver to the base. The occurrences of Tropical Storm Erika and Hurricane Fred delayed the arrival of the supply barge by three days, so when the cutting equipment arrived the contractor had to move fast. An operator began drilling the first 18-inch-diameter hole the day the equipment arrived. The hole was completed and the 7.3-foot-long core removed within five hours. The core weighed approximately 2,000 pounds and was lifted from the opening by crane. The core drill operator then positioned the equipment at the next specified location and repeated the process. The core drilling was going well for the contractor until the secondto-last hole when, as the bit reached a depth of approximately 4 feet, the stainless steel spindle on the hydraulic core drill machine broke. This The cutting contractor created six cores in four days.

was a huge problem, considering there was no commercial shipping to and from GTMO. Fortunately, Robinson found a machine shop on base that was able to repair the spindle— only to have it break again. It was suspected that the 8-foot-long core bit and some possible misalignment issues were the cause. The team from Accu-Cut returned to the company’s shop in Florida, where a replacement drill spindle was fabricated using 4140 alloy steel. The spindle was given to a representative of the general contractor who took the next Navy flight to GTMO out of Jacksonville and delivered the part to the jobsite. An on-site mechanic was able to replace the spindle and two of Orion Marine Construction’s crew members, who had been assisting Accu-Cut with the core drilling operations, were able to complete the last one-and-a-half holes with instruction from Robinson. The crew members also removed a 16-inch-long section of a core that did not break off clean at the bottom of a hole. Several 4-inch-diameter holes were made into the core section using a handheld core drill and 7 feet of extension. In total, Accu-Cut completed the core drilling of six holes in the pipe piles at the Naval Base. This work created concrete cores that weighed a total of 12,000 pounds. “It is very difficult to work on a Navy base even within the continental U.S.,” said Robinson. “They are very strict on every aspect of safety and planning at all their bases. Add to this the isolation of GTMO and you pretty much only have what you bring for spare parts. We brought every part for our hydraulic core drill machine, all the bearings and seals, all drill carriage parts, rollers gears, bushings and a spare carriage. However, we did not bring a spare spindle and, of course, that was the part that broke!” “The Navy requires strict adherence to their EM385 specification and we had to complete Job Safety Analysis and Activity Hazard Analysis forms for every aspect of the operation. This included the setup of the core drilling equipment and the hydraulic power unit, core drilling tasks and the rigging and lifting of the cores. We had to have preparatory meetings with all parties involved—NAVFAC, URS/RQ and Orion—all before any work could begin.” In spite of the delays encountered during the job, Accu-Cut completed all tasks in a timely manner and to the satisfaction of the general contractor and other authorities involved. The cutting contractor’s successful

work on the initial demolition phase of the old pier was the reason why the team was asked to return to resolve the pipe pier issue on the new construction. Between these two GTMO jobs, the concrete cutting company had worked with Orion to remove a pier at another Navy base and so was a natural choice to return and complete these core drilling tasks. â&#x20AC;&#x153;Accu-Cut has a long successful history of performing unique demolition projects for Orion Marine Construction, which in many instances has required Accu-Cut to develop and fabricate specialty equipment to overcome the difficult and unique conditions on respective projects.

AWARDS World of Concrete Awards Ceremony Celebrates CSDA Members

The most innovative and challenging projects completed by CSDA contractors in 2015 were recognized during a prestigious World of Concrete ceremony in Las Vegas.

The association, in conjunction with the Praxis event, hosted the third annual Concrete Openings Awards. This year’s ceremony was staged at the Praxis booth in the outdoor Gold Lot of the Las Vegas Convention Center and drew a good crowd. CSDA Executive Director Patrick O’Brien acted as Master of Ceremonies while the association’s president, Kevin Baron, presented the awards to the winner. World of Concrete attendees and members of the industry media joined CSDA to celebrate with the winning contractors over champagne and strawberries. The inaugural Concrete Openings Awards ceremony was held in 2014 to showcase the best projects covered in CSDA’s official magazine and recognize the contractors who performed the work. This year,

sixteen job stories were split into four categories and put before a panel of judges. The panel scored each job based on its pre-planning, use of innovation, degree of difficulty and quality requirements. The project with the highest score in each category was declared the winner. “Just as I have seen for the past couple of years, these 2015 entries show the amazing skill and intricate planning that go into concrete cutting, polishing and imaging jobs,” said Tom Stowell, CSDA Past President and industry professional from Gainesville, Georgia. “It was a pleasure to be involved in the judging process and I congratulate the winners for their fantastic work.” These winning projects are just some of the innovative and complex jobs being done by CSDA contractors everyday on jobsites around the U.S. and beyond. The association encourages all concrete cutting, breaking, polishing and imaging members to submit their best job stories for publication in Concrete Openings, and to consider entry to this year’s awards. Look out for more information about the Concrete Openings 2016 Awards later in the year.

The winner of the this category cut and removed approximately 100,000 pounds of concrete as part of a two-phase, $5.2-million renovation project at the Adler Planetarium in Chicago, Illinois. The work involved creating several 9.5-foot-tall openings, some as wide as 6 feet, in the 14-inchthick exterior wall of the Doane Observatory, home to the largest aperture telescope available to the public in the Chicagoland area. A raked concrete finish had to be chipped from the outer wall to position track-mounted wall sawing equipment for cutting the openings. An interior wall within the cylindrical-shaped structure was made up of 12 concrete sections that were positioned together at 30-degree angles. This meant using precise calculations and cutting techniques to ensure the work was completed within specified tolerances. Further precise cutting and removal tasks were completed to help transform the observatory into a modern tourist attraction.

This contractor was tasked with cutting and removing a giant 400-ton concrete shielding door from a laboratory within a scientific research center in Chicago, Illinois. The moveable concrete structure weighed in excess of 800,000 pounds and served as a giant door for a previous experiment at the lab. However, it stood in the way of renovation works and was to be removed. The successful completion of this highly technical concrete sawing project required two years of planning, using a diamond wire saw to dissect the door into smaller manageable blocks for removal. By the end of the job, operators had cored approximately 60 feet of concrete and cut over 2,100 square feet of concrete, creating over 50 concrete blocks â&#x20AC;&#x201C; some of which weighed 16,000 pounds. The contractor also had to cut through steel plating and five 3-foot I-beams, creating three bocks weighing an average of 25 tons each.

In the case of this winning project, the 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. The General Zebulon Pike Lock & Dam No. 11 is located between Dubuque, Iowa, and rural Grant County, Wisconsin, on the Upper Mississippi River. The lock hinge issue would eventually lead to the failure of the gates, so the contractor was tasked with core drilling 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. A hydraulic core drill fitted with 13.875-inch-diameter carbide bits was utilized for the work and spun at a rate of 50 RPM to cut the pins free.

The first international Concrete Openings Award winner, the winner of this category completed an extensive amount of cutting work to help remove 1,200 tons of concrete as part of a two-year, $1.9-billion widening and tunneling scheme on a motorway in Auckland, New Zealand. The work included over 1,640 feet of flat and wall sawing, 538 square feet of wire sawing and the coring of almost 200 holes for the replacement of a bridge as part of the motorway widening work. St Lukes Road spans the North Western Motorway in Auckland via a 144-foot-long by 53-foot-wide reinforced concrete bridge, which consisted of 24 precast, pre-tensioned beams. Each beam was 43 inches tall and transitioned from 35 inches wide at the top to 20 inches at the bottom, spaced at 4.1-foot centers. The bridge had a 4 to 8-inch-thick topping slab and two abutments, one of which remained in use for a new bridge while the other was cut up and removed. In addition, a center pier and headstock structure were removed. A combination of flat sawing, core drilling, wall sawing and wire sawing techniques were used to decommission the bridge.

Next, the cutting team set up wall sawing equipment for the creation of 10 dock door openings in 10-inch-thick precast concrete walls. The contract specified that some openings be 10 feet square and the others 14 feet square. IDS, Inc. planned to create each opening by cutting four smaller pieces to lift out individually. Operators began by core drilling two 6-inch-diameter pick holes through each of the marked sections with a Shibuya core drill supplied by Diteq Corporation.

was applied to prevent the cut sections from tipping out prematurely. Before all four cuts were completed for each piece, rigging was run through the core-drilled holes so that the cut concrete section could be removed by crane. To complete each opening and leave a clean finish, IDS, Inc. used a Core Cut 8000 ride-on curb cutting saw from Diamond Products to make flush cuts along the bottom level with the slab. Once cutting of the dock doors was complete, the contractor moved on to create 18 window openings measuring 5 feet wide and 4 feet tall in some of the same 10-inch-thick precast concrete walls. As per the dock door openings, a core drill was used to create pick holes through each of the marked locations before the same wall sawing techniques were applied for the top and vertical cuts. To avoid overcuts in the corners of the openings, IDS, Inc. employed a concrete chain saw from ICS and completed over 1,200 linear feet of cuts in the 10-inch-thick walls.

All window and dock door openings were made through 10-inch-thick precast concrete walls.

During the cutting and removal of the dock door and window openings, the main focus was the safety of IDS, Inc. employees while working around large vertical cut sections and aerial lifts. All employees were fully trained and certified on the operation of the equipment, including the aerial lifts. This generated clear communication with the general contractor and the precision necessary to make the operation go smoothly. The cutting contractor performed daily walk-throughs of the work area before work began and completed Job Safety Analysis forms that were submitted to Raco. IDS, Inc. spent over five months working at the Coca-Cola Bottling Company UNITED distributing center in Montgomery. The job was completed successfully on time, within budget and with no incidents. One issue complicating the job was the safe disposal of concrete slurry. IDS, Inc. employees had to transfer the collected slurry to the back of jobsite, which was a round trip of 20 minutes

and added a lot of time to the work. There was also a delay for the installation of steel reinforcing members in the tilt wall panels where openings were cut. This presented a challenge, as the contractor had to avert from typical mounting methods used for its wall saw. With some careful and safe planning from lead operators Matt Jeffers and Mark Taylor, the team was able to overcome this challenge with innovative mounting solutions. “The Coca-Cola bottling distributing center was a great project for IDS, Inc., since we had a previous relationship with Raco and the company’s superintendent, Rick Kelly. Communication and pre-planning was key for us, as this was not the only large project that we had going on at the time,” said Sanders. “Our solid relationship with the general contractor, our previous experience with large jobs and the proximity of the facility to our office were all contributing factors to us being awarded this work. Raco did not choose us based on price, but on our reputation, quality of work and focus on site cleanup,” he added. This CSDA member proved that when specialist concrete cutting techniques with diamond tools are required, customers need the real thing. There is no substitute for professional, certified operators that can perform detailed sawing and drilling methods to complete work to a high standard.

A series of wall panels were cut and removed from the DakotaDome.

DakotaDome Renovation

CSDA Member Scores Big with Sports Stadium Upgrades

he University of South Dakotaâ&#x20AC;&#x2122;s Athletics Department recently made renovations to its flagship building, the DakotaDome, as part of a wider $66-million new construction project. This renovation work consisted of cutting 8-foot-wide pre-cast concrete pieces from the walls of the dome, the top cuts being 30 feet from the ground, to create 25-foot wide and 24-foot tall openings. 2 2 | M ARC H .16

The university has broken ground on a Sports Performance Enhancement Facility Arena, a Science, Health and Research Lab and an Outdoor Track and Soccer Complex. The three projects are projected to be completed before the start of the 2016-17 academic year. Openings created in the DakotaDome are being used to install structural steel that will support a connection point between the dome and the new facilities. They will also create viewing windows that overlook H. Lauren Lewis Field for members of the universityâ&#x20AC;&#x2122;s sports clubs to watch games from above the south end zone. CSDA member Northwest Concrete Cutting & Crane Service of Sioux Falls, South Dakota, was contracted by Mortenson Construction of Minneapolis, Minnesota, to create the openings using diamond tools. The task involved cutting partial sections of existing concrete wall panels that each measured 24 feet tall, 8 feet wide and 3 inches thick with 13-inch-thick T-stems that had

seven post-tensioned cables. There were five openings specified to be cut and removed by crane. The width of two of the openings spanned two separate panels, another spanned four panels and two openings for walkways each spanned one panel. The cutting contractor was also responsible for flat sawing and removing an 11-foot-wide and 180-footlong section of 10-inch-thick asphalt. This would provide the general contractor with an area to install footings for structural steel as part of the new construction. The first task for Northwest was the cutting and removal of the asphalt floor section. A 40-horsepower electric flat saw from Diamond Products powered by an 80-kilowatt generator was used to make the cuts, while the contractor’s skid steer was fitted with a scrubber to haul the cut pieces to the disposal point. A spotter walked behind the skid steer at all times to eliminate the possibility of passing students being hit. This task took around 24 hours to complete. Next, the cutting team carefully planned and set up the work area for the removal of the wall panels. Working on a dome structure with limited access points, the contractor had to be conscious of the existing construction and red iron being installed for the new construction. Operators were left with 4 feet of space from the dome walls on the exterior of the new building, with some cut points positioned 45 feet from the ground. Where the precast panels formed T-stems, the working space was just 2 feet. To perform the job safely and efficiently, a swing stage was used and was mounted to the roof of the dome. Once the swing stage was set in place, layouts and other preparatory work for cutting was completed. Meanwhile, on the inside of the dome, two men, including a certified crane operator, set up the crane for the safe lowering of the cut pieces. Two concrete cutting operators were positioned on the swing stage and drilled two holes so that rigging could be passed through and secured. This involved bolting on two swivel hoist rings that were each rated for 15,000 pounds. All required items of rigging, hoisting and personal protective equipment were provided by Northwest, including harnesses and hi-visibility vests. The cutting process for successfully removing the wall panel sections meant splitting each one into three pieces, each

The DakotaDome Located in Vermillion, South Dakota, the university was founded in 1862 and is the state’s oldest university. James W. Abbott, J.D. has held the role of university president since 1997. USD has a total enrollment of 9,971 undergraduate and graduate students. The DakotaDome, a 10,000-seat stadium, serves as the cornerstone of the Coyote Athletic Department. A multi-purpose facility, it is home to five intercollegiate sports, including football, basketball, volleyball, track and field and

swimming and diving. Originally constructed in 1979, the dome received a new $13 million steel roof in 2001. Additional upgrades followed including the installation of a customized Daktronics Sports Marketing video board, concourse and concession improvements, women’s locker room renovation and press box updates. Work continued in 2007 with the renovation of the sports medicine area, replacement of men’s locker room, reconstruction of the equipment room and replacement of the arena floor.

weighing 5,600 pounds, and cutting through some T-stems. It was specified that the contractor was only allowed 1,500 pounds of weight per square foot for crane pads and a hauling cart. This was to avoid damaging the asphalt under the football field surface. First, the contractor cut a 2.5-foot-tall section from the top of the panel before proceeding to cut pieces that were each 10.75-foot-tall. Operators on the swing stage used a K2500 hand saw and a K3600 MKT ring saw from Husqvarna Construction Products, with each cut across the panel and T-stem taking approximately one hour. Once cutting was complete, the piece was

lowered to the interior floor of the dome before being removed from the building by trailer. By dissecting the cut sections into three pieces, the contractor made sure that the weight of the concrete being lowered was under 70% on the craneâ&#x20AC;&#x2122;s load chart. When all panel sections had been removed, Northwest was required to go back to the openings and cut the T-stems at an angle for roofing contractors to tie into. The cutting of the wall panels came with some challenges, as the dome was operational and student athletes from the university were attending practice sessions within the building.

was secured on the trailer and ready to be transported out of the dome, the team used a combination of warning lights and spotters to avoid potential hazards. Once safely outside, a 12,000-pound all-terrain lift was used to move the cut pieces to the disposal point. The use of a swing stage was a first for some of the cutting contractor’s operators, but safe practices were adopted to ensure a sturdy work platform. Training was provided on the safe use of the swing stage and the operators were given time to familiarize themselves with correct operation of the equipment. By ratchet-strapping each corner of the stage to an anchor in the wall, it was kept tight to the dome wall and was prevented from moving while cutting. The summer heat and humidity also presented a challenge.

The openings will be used as part of a wider construction project at the location.

Operators wore harnesses and were positioned from 22 to 45 feet up on the swing stage in July with temperatures of up to 97 degrees. A cooler of water was placed on the stage and refilled whenever possible. A temporary cover was also set up above the cutting area to provide shade. During the DakotaDome job, Northwest Concrete Cutting & Crane Service operators completed 320 linear feet of hand sawing and ring sawing, flat sawed 870 linear feet of 10 inch asphalt, hammer drilled 40 holes for crane rigging and removed all asphalt and concrete to a dumpster on the opposite end of the dome. The job took four weeks to complete and involved the removal of over 75,000 pounds of concrete. â&#x20AC;&#x153;Being selected for this project came down to a few reasons. Northwest Concrete Cutting & Crane Service has NCCCO certified crane operators, riggers and signal men on staff. We also have a good reputation for doing quality work with good time management. We have shown many customers that we complete work in a clean and safe manner. Our experienced staff provide us with the ability to rise to all challenges placed before us.

Polished Perspective

Tales From the Dark Side: Horror Stories in Polished Concrete Finishes By Chris Bennett

ver the years, I have consulted on quite a few projects with exposed concrete (polished concrete) floor finishes. There have been successes and then there have been complete tragedies—slabs so scary that all parties involved lose sleep and sanity for the remainder of their lives! Perhaps the only comforting part of these tragic journeys for most, is realizing they are not alone. When sitting around the metaphorical construction campfire, you meet other weary travelers who whisper their grim and fearful battles with concrete. Two of those travelers, Keith Robinson of Dialog Design, and Jessica Ledger of CSDA member Royale Concrete, have been brave enough to retell their horror stories here.

The slab was overworked. The joints were cut two weeks too late and, in an effort to speed-up the curing for the construction schedule, the GC used open-flame propane heaters in some (but not all) of the areas. This caused curing and drying times to be different across the surface of the slab as well as carbonation and other aesthetic problems. After not hitting the specified design intent, the GC did the scariest thing of all—asked for more money to fix its mistake!

CONCRETE

TALES FROM THE DARKSIDE

OEL!AMIN N IS D

PLEASE JOIN US, GENTLE READER, AS WE BRING YOU TALES FROM THE DARK SIDE OF CONCRETE! THESE STORIES OF TERROR ARE TRUE.

This slab was buried in an unmarked grave in the forsaken-facility cemetery, but still tortures the owner to this day.

Keith Robinson had a large government project involving exposed concrete floors. Keith and his team had prepared for everything they had set out to do, included the concrete supplier and finisher as part of their pre-slab meeting, reviewed design intent and had even taken the time to narrow installers down based on visiting previous successful installations. Just when everyone thought everything was going according to plan, the worst thing possible happened. The General Contractor (GC) decided to take over design intent. Without clearly communicating what was happening, the GC changed the concrete supplier. The supplier, having not attended the pre-pour meeting, was unaware of the expected outcome and thus changed the mix design. Sadder still, was the depressing decision for the GC to self-perform the slab installation! Not having the necessary equipment, the GC rented equipment and hired casual labor.

During my own days in manufacturing, I was consulting on a polishing project in Florida for a wealthy client with very specific design ideas for his commercial office building. The floors were to be bone white with large, jet-black aggregate and then polished to a semi-gloss sheen. Research was conducted for the right amount of aluminum oxide in the mix to create the desired shade of white and a special supplier of dark aggregate was found outside of state lines. The special aggregate was purchased and then shipped in for the construction of the slab on grade. Everything seemed to be going along well and then the bottom fell out! Too much fly-ash was added to the white mix because the supplier had not read the specification. It turned the concrete a ghoulish grey. The uncertified placement contractor then proceeded to vibrate the

special aggregate too deep into the slab. This design intent had indeed died a ghastly, horrible death. Exposed aggregate of any kind was no longer an option and nothing short of cutting out and repouring would ever make this grey slab white. When questioned as to why he had murdered the innocent design intent, the cruel contractor’s only reply was, “I have been doing concrete for 30 years. Nobody is going to tell me how to do my job.” Sometimes, if you listen at night, you can still hear the spirit of the design intent’s macabre howling, trying to find its way back into the slab. It was a day just like any other for Jessica Ledger, until the phone rang at Royale Concrete. “Help,” the voice said.

“My brand new slab is delaminating and I don’t know why!” Royale Concrete had been contracted to install a polished concrete floor at this very facility and this news did not sit well with Ledger. Rushing over just after midnight, she discovered that the slab was indeed delaminating. It had only been poured within the last six months and she knew this was not supposed to be happening. As if delamination was not bad enough, the slab was also demon-discolored and cracking! “The customer ran a chain test across the slab and realized there were several hollow spots in the floor and the delamination was confirmed,” said Ledger. “We were brought in as a contractor that could help fix the problem. We were the second contractor to submit a proposal, but the first properly qualified to effectively solve the issue.” What did Jessica have that the other concrete contractors did not have? Experience and training. But how does Jessica let decision-makers know she has these two important items? Certification. The Concrete Sawing & Drilling Association has a standard and training program for educating professionals on how to measure surface texture grades (STG) for concrete surfaces and it is called CSDA-ST-115. Ledger and her team are not only ST-115 certified, but also have another third-party training and certification from CSDA member Select Concrete Solutions (SCS). This company provides training on slab placement as well as finishing and polishing that specifically address moisture issues. There can, indeed, be many scary scenarios related to the installation of concrete floor systems. However, proper training and certification combined with the use of defined best practices can help most concrete polishing contractors sleep easy and avoid nightmare projects. I hope you have enjoyed this journey to the dark side of concrete. Sleep well… if you can!

Safety Counts

Ladder / Scaffolding Safety and Fall Protection

ccidents involving falls, particularly from ladders and scaffolding, can be some of the most severe in the workplace. Fortunately, they are also some of the most preventable. Using good judgment, being aware of the work environment and wearing the proper fall protection, when necessary, will help keep operators safe on the job. The rules and guidelines detailed in this article should be followed when working on ladders, scaffolding or working at heights. LADDER SAFETY OSHA Reference (Subpart X) 1926.1051 – .1053 Ladders are not frequently used in the sawing and drilling industry. However, this lack of use may be more of a problem than first thought. The fact that operators don’t climb or work from ladders very often may cause as much of a safety concern as if they worked from them every day, as the operators are not used to working with or around ladders. Because of this unfamiliarity, ladders can pose a significant hazard. Here are a few general rules associated with ladder safety. Many of these rules can be applied to a fixed ladder. 1. The use of ladders with broken or missing rungs or steps, broken or split side rails or other defects, is prohibited. 2. The feet of portable ladders shall be placed on a solid base and the area around the top and bottom of the ladder shall be kept clear. 3. Straight or extension ladders shall be used at a pitch of 4 feet (1.22 meters) vertical to 1 foot (0.3 meter) horizontal. 4. The side rails of ladders used for access to higher levels shall extend at least 36 inches (91.4 centimeters) above the landing or work platform.

3 0 | M ARC H .16

5. Access ladders in use shall be tied off, blocked off or otherwise secured at the top to prevent displacement. 6. Always face the ladder when ascending or descending. 7. Job-made ladders are not allowed to be built by employees and should not be used. SCAFFOLDING SAFETY Scaffolding is a temporary structure used to support people and material in the construction or renovation of buildings and other large structures. This modular system of metal pipes or tubes should provide a safe workplace with safe access suitable for the work being done, but can be a potential hazard for sawing and drilling operators if not used correctly. To ensure the highest possible level of scaffold safety, operators should be aware of the following guidelines: 1. Fall protection is required when working on scaffolding over 10 feet (3 meters) off the ground. 2. The assembly and dismantling of scaffolding must be overseen by a supervisor and inspected prior to use.

3. Each section of frame scaffolding must be equipped with two cross braces. 4. Each area of the scaffolding must be fully planked. 5. Scaffolding sections stacked over four sections high, or 20 feet (6.1 meters), must be tied off to the building to prevent it from falling over. 6. Mud sills and base plates must be placed under each leg of the scaffolding. Mud sills must be at least 12 inches by 12 inches (30.5 centimeters by 30.5 centimeters). 7. Damaged scaffolding may not be used. 8. An access ladder or other safe means of entry is required to gain access to the scaffolding. 9. Contractors may not use each other’s scaffolding. FALL PROTECTION Identifying fall hazards and providing protection for operators is the best way to reduce or eliminate the risk of falls. The U.S. Department of Labor lists falls as one of the leading causes of traumatic occupational death, accounting for eight percent of all occupational fatalities from trauma. Any time

CSU-201509-Concrete Openings hlf pg_Layout 1 7/15/15 4:58 PM Page 1

a worker is at a height of 4 feet or more, the worker is at risk and needs to be protected. The following rules should be adhered to when assessing the risk of falls in the workplace: 1. A floor is considered protected if it is barricaded or protected by a cover that is capable of supporting twice the maximum intended load. 2.Employees may not work without fall protection in areas where an unprotected floor or wall opening exists with a fall hazard of 6 feet (1.83 meters) or greater. • Wall openings are defined as a wall or window opening with dimensions of 18 inches (45.7 centimeters) by 30 inches (76.2 centimeters) or greater and a fall hazard of 6 feet (1.83 meters). • Floor openings are openings of 2 inches (5.08 centimeters) by 2 inches or greater offering a fall hazard of 6 feet (1.83 meters). • Employees may not work without fall protection near any unprotected area where a fall hazard of 6 feet (1.83 meters) or greater exists. 3. Railings are considered fall protection if they are installed as a top and/or mid rail at approximately 42 inches (106.7 centimeters) and 21 inches (53.3 centimeters) respectively. The railing system must be able to support at least 200 pounds applied at any point in any direction. This does not apply to some scaffolds and boom lifts. Abiding by these rules on the job site and reviewing these rules with new employees will assist in reducing the number of on-the-job accidents. Violation of these safety rules may result in dismissal of an employee and/or the company being investigated by OSHA. Gross misconduct may result in immediate termination of an employee by the company.

Helipad Under the Radar Fast, Accurate GPR Imaging on Hospital Landing Platform

hen the University of Utah Hospitalâ&#x20AC;&#x2122;s Air Medical Transport Services (AirMed) needed to place anchor brackets to secure a railing next to its helipad stairs, it needed help locating several highly tensioned posttensioned cables. Had these cables been struck while drilling holes for the anchor brackets, they would have caused significant damage or injury.

Correctly identifying the position of post-tensioned cables beneath the helipad would avoid accidents while drilling anchor holes.

AirMed operates 24 hours a day from its main base at the University of Utah Hospital and from satellite bases throughout northern Utah and Wyoming. University personnel contracted the Utah/Idaho/Montana office of CSDA member Ground Penetrating Radar Systems, Inc. (GPRS), based in Toledo, Ohio, to inspect the helipad using ground penetrating radar (GPR) equipment operated by an experienced technician. To locate the reinforcement, the GPR imaging contractor used a 1600 megahertz antenna and marked findings directly on the concrete for easy interpretation. GPR emits no radiation and is safe for others to work around the area near the scan location, making it ideal for the work at what was an active and extremely busy helipad site. Adam Kubicki, the GPRS regional manager for the Utah/ Idaho/Montana office, had a chance to get up close and personal with the AirMed mission when scanning the helipad. He says, “The helicopter crew came out when I was scanning. They were extremely interested in what I was doing and appreciative of how we were making their facility as safe as possible. After I showed them how the equipment worked, they let me jump in the helicopter’s pilot seat. It was one of the most

amazing experiences I have ever had on the job and I was proud to play even a small role in helping them with their mission.” Kubicki’s GPR system included an antenna, a power supply and a control unit with electronics that triggered the pulse of radar energy the antenna sends into the subsurface. The antenna received the electrical pulse produced by the control unit, amplified it and transmitted it into the helipad at a set frequency. Antenna frequency is one major factor in depth penetration. The higher the frequency of the antenna, the shallower into the ground it will penetrate, but the finer the resulting resolution. The GPR equipment sent its pulse of radar energy into the concrete. Subsurface variations, including rebar, post-tensioned cables, pipes (both metallic and non-metallic), wire and voids caused the signal to bounce back. For this particular job, the technician scanned an area of the helipad measuring 10 feet by 2 feet to a depth of 8 inches. It took less than one hour to cover the specified area with the antenna. The technician made a pass every 6 inches, moving the antenna north to south and east to west until the specified area had been covered. Results from the GPR imaging indicated the presence of several post-tensioned cables within the planned drilling area.

Imaging Insight from CSDA Many CSDA members have embraced technological advancements in the industry and added GPR to expand their sawing and drilling operations into full service companies. Some have even created separate divisions or businesses. In response to this trend, CSDA added an GPR Imaging Contractor membership category in 2013 to represent those who offer GPR as a primary or additional revenue stream. In addition, a CSDA GPR Imaging Committee has been formed with the purpose of promoting the use of imaging technologies, primarily focusing on GPR.

Based on the data provided, Kubicki was able to accurately mark the locations of the cables on the helipad with colored spray paint. The strength and time required for the return of the reflected signals was recorded on a computer integrated into the system before the data was compiled and submitted to the client. The data collected was carefully analyzed to make specific recommendations about embedded/buried obstructions and voids that would have had an effect on the anchor drilling for the new railing. In this case, GPRS was able to identify to the University of Utah Hospital that post-tensioned cables were below the concrete surface within the planned anchor installation area. The markings made by GPRS, Inc. gave the railing installation contractor a visual of what was below the helipad so that the drilling of the anchor installation holes could be completed without incident. With help from this CSDA member, the University of Utah Hospital was able to safely secure the railing by the helipad. The correct identification of hidden objects and hazards is often critical to the success of many projects were sawing, drilling or other excavation and demolition methods are required. The speed and accuracy with which skilled GPR technicians can scan an area can prove extremely beneficial and cost effective. REVIEW AND COMMENT ON THIS ARTICLE AT: WWW.CONCRETEOPENINGS.COM

Core Health Industry Bits continued

On-the-Job Emergencies By Erin O’Brien

very concrete company should have its own safety guidelines and training to ensure the health and safety of its operators and employees on the jobsite. These should include written policies and procedures, safety precautions, training and an emergency plan. Since the risk of injury is high in the construction industry, it is vital that companies train employees to reduce the risk of injury. However, accidents and emergencies do happen, and often do not occur as a direct result of an incident on the job. Some health emergencies can occur without warning or provocation and require immediate attention. These types of emergencies are often not covered in company safety guidelines, but should be addressed, as employees equipped with this knowledge may be able to save a co-worker’s life. Most common medical emergencies may not be caused by an incident on the job, but as the result of a pre-existing, possibly unknown condition. These medical emergencies include, but are not limited to: heart attack (myocardial infarction), stroke, asthma attack, diabetic shock, epileptic seizure and appendicitis. Other medical emergencies that could be triggered by worksite conditions include, but are not limited to: hyperthermia, hypothermia and concussions. The following section will discuss each of these conditions, how to identify them and what proper treatment can be given by other employees.

3 8 | M ARC H .16

HEART ATTACK (MYOCARDIAL INFARCTION)

STROKE (ACUTE CEREBROVASCULAR ATTACK)

Heart attacks are caused by a blockage of the heart’s coronary arteries (vessels that carry blood to the heart muscle itself), causing a depletion of oxygen to the cardiac muscle, eventually resulting in necrosis (permanent tissue damage). Symptoms include intense chest pain, possibly radiating to the jaw, left shoulder and arm, difficulty breathing, profuse sweating, nausea, vomiting, cyanosis (bluish skin color), shallow breathing and a rapid, irregular pulse. Immediate action is required; calling 911, or Emergency Medical Services (EMS) should be the first step. Next, continue to monitor the victim. Make sure the victim is in a stable environment and if cardiac arrest (complete stoppage of the heart) occurs, begin CPR if there is a trained person available. If an Automated External Defibrillator (AED) is available, use it as directed.

A stroke occurs when there is a rapidly developing loss of brain function(s) due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of glucose and oxygen supply) caused by a blockage of a blood vessel in the brain, or hemorrhage. As a result, the affected area of the brain is unable to function, leading to inability to move one or more limbs on one side of the body, inability of the stroke victim to understand or formulate speech or inability to see one side of the visual field. Symptoms will usually have a rapid onset and may also include muscle weakness on one side of the body, altered mental state and balance and ambulation problems. EMS should be called immediately, and the person’s pulse and breathing should be monitored.

ASTHMA ATTACK

APPENDICITIS

CONCUSSION

An asthma attack can be triggered by environmental conditions, such as allergens or foods, although some asthma attacks are not environmentally triggered. Often, a person with asthma will be aware of his or her condition and carry an inhaler, especially in moderate to severe cases. Symptoms of an asthma attack include dry wheezing, difficulty breathing—especially in exhaling— and chest tightness. In the case of an attack, the person should use their inhaler as soon as possible, and others should assist in keeping the victim calm and encouraging deep, rhythmic breathing. If the victim does not have an inhaler, or the attack cannot be controlled in a few minutes, call EMS.

While appendicitis is most common in men under the age of 25, occasional cases in older individuals do occur. Symptoms include pain in the abdomen, tenderness and muscle rigidity in the lower right quadrant of the abdomen, possible nausea and vomiting. Symptoms will progressively worsen and may also include fever and rapid pulse. The person should be taken to the hospital for further evaluation, or EMS should be called.

Concussions are the result of damage to the brain tissue, due to trauma to the head, such as an object striking the head or a person falling and hitting their head on a hard surface. Symptoms include mental confusion, alteration of mental status, amnesia, slurred speech, incoordination or balance deficiencies and possibly loss of consciousness. These symptoms could last from a few minutes to an extended period of time exceeding several days, depending on the severity of the concussion. If the symptoms are not severe, do not last more than a few minutes and there is no loss of consciousness, the person usually does not need immediate medical attention. Symptoms lasting longer than 15 minutes or a loss of consciousness require medical attention. If a person loses consciousness or the symptoms do not resolve and begin to worsen, call EMS immediately. If there is ever any doubt on the treatment of any of these conditions, it is better to be safe and call EMS. Every company should also have an Emergency Action Plan (EAP) in place, with details on how to contact emergency services, other important numbers to call and a chain of command—who else needs to be notified of the emergency? It would be beneficial to have at least one person in the company who is trained in CPR/AED and first aid. Having an AED on-site could mean the difference between life and death for a person having a heart attack. Local Red Cross chapters and the American Heart Association offer this type of training.

DIABETIC SHOCK Diabetic shock is caused by insulin levels in the bloodstream that are either too low or too high. Symptoms vary depending on the condition, but can include a rapid or gradual onset, rapid pulse, labored breathing, altered mental state (confusion, stupor, irritability), warm, dry, red skin or cold, clammy and pale skin, intense thirst, nausea, vomiting, abdominal pain, dizziness, headache, profuse sweating, fainting and convulsions. Most people will be aware of a diabetic condition and be able to treat themselves before symptoms become too severe. In many cases, a small snack or juice will help stabilize blood sugar levels. Otherwise, EMS should be called. EPILEPTIC SEIZURE An epileptic seizure can have no apparent cause and will most often occur without warning. As with diabetes and asthma, most epilepsy patients are aware of their condition. Most seizures will involve involuntary whole-body muscle contractions and loss of consciousness. Some, however, may not involve a loss of muscle control, but complete unresponsiveness for an extended period of time. These seizures can last from less than a minute to several minutes. If a person is experiencing whole-body muscle contractions, remove any objects from the area that they could injure themselves on, DO NOT put anything in their mouth and if they begin to vomit, roll them onto their side and try to keep their airway open. In the case of this type of seizure, EMS should be called. If the seizure involves unresponsiveness and no muscle convulsions, EMS does not need to be called unless the condition does not improve after about 15 minutes.

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

HYPERTHERMIA Hyperthermia is caused by an increase in body temperature and the inability of the body to effectively cool itself. Large body mass, advanced age, poor conditioning level, poor hydration and some medications can predispose a person to hyperthermia. The condition is most common in hot, humid and sunny environments. Symptoms include excessive sweating, rapid and weak pulse, muscle cramps, dizziness, fainting, nausea and vomiting. In advanced cases, the person will become confused, stop sweating, have hot, red, dry skin and dilated pupils. The person should be immediately moved to a cool location and body temperature must be lowered. This can be achieved by cold water immersion or cold, wet towels being placed on the head, neck, under the armpits, behind the knees and in the groin area. EMS should be called immediately. If possible, the person should be in a shaded area with a fan directed towards them. The priority in this situation is always to lower body temperature as soon as possible. HYPOTHERMIA Hypothermia is caused by a decrease in body temperature. The condition is most common in cold, damp and windy environments or by immersion in cold water. Symptoms include a slow, weak pulse, dilated pupils, shallow, irregular breathing, shivering, motor impairment and decreased mental focus. In severe cases the person may have developed frostbite (tissue damage in the extremities) and a desire to sleep. Treatment includes moving the person to a warm environment, removing any wet clothing and wrapping in a dry blanket. If re-warming is done with hot water, rapid changes in temperature should be avoided. The person should be gradually re-warmed to avoid burning the skin and causing other internal problems. If hypothermia or frostbite is moderate to severe, call EMS.

GPR: To calibrate, or not to calibrate? By Jami Harmon

hen the need for concrete inspection arises, ground penetrating radar (GPR) is an ideal nondestructive technology for the job. GPR systems have continued to gain popularity in concrete imaging since the 1980s. Non-destructive testing methods are greatly preferred for locating buried metal targets or electrical conduits in existing structures. For many decades, X-ray technology was the predominant non-destructive technique used to locate and identify embedded targets. While concrete X-ray technology is still useful in some rare cases, scanning concrete using GPR has somewhat overtaken X-ray technology. It is now seen as the most efficient process to employ when locating rebar, post-tension cables, conduits or other targets in concrete prior to concrete cutting, coring or any other destructive procedures. GPR technology allows personnel to work quickly, efficiently and accurately in real-time. Unlike X-ray technology, concrete GPR imaging equipment can locate targets and their depths safely, without the need to vacate the jobsite or handle hazardous materials. Yet, the technology itself still requires a significant amount of education— both with operators and contractor clients. A primary question that continues to come up in industry presentations, association meetings and on the jobsite is, “do I need to calibrate my RADAR system?” The term ‘calibrate’ is defined as the correlation of readings of an instrument with those of a standard in order to check the instrument’s accuracy, or to adjust readings to take external factors into account or to allow comparison with other data. Relative to GPR, systems are calibrated to ensure accuracy and precision. For this type of equipment, calibration comes in two forms; distance and depth.

4 0 | M ARC H .16

DISTANCE & POSITION: THE IMPORTANCE OF THE DISTANCE MEASURING INSTRUMENT A GPR system is comprised of three major components; the control unit, the antenna and the distance measuring instrument (DMI). The DMI, also commonly known as the survey wheel or encoder, is typically some type of optical encoder mechanically coupled to a wheel which rotates as the GPR antenna is moved. The encoder generates pulses which, when calibrated, has two important functions. The first is that it measures the distance traveled, and therefore allows the Figure 1: Survey wheel calibration screen from a GPR control unit. user to determine the position of targets. The second is that it sends a DEPTH: DRILLING DOWN ON fixed number of pulses per revolution to THE DEPTH SCALE the control unit used to trigger the antenna Equally as important as the accuracy at equal distance intervals (scan spacing). of distance and position, is the precision of As such, when one is speaking of doing a the depth. There are several ways in which ‘calibration’ on the jobsite, they are typically one can determine depth. Each method referring to calibrating the DMI to ensure includes setting up the GPR system with distance and positon accuracy.

an arbitrary time zero, usually above the true surface to ensure the top of the surface is captured in the data. This has to be taken into consideration and corrected. In many systems, this process can be done with a quick adjustment. This is the simplest, but least accurate method of depth calibration. By selecting a predetermined value (concrete type), a depth scale is established that is accurate within 20 percent. Sometimes, if the objective is to locate an area in the concrete to safely core drill and opening, a very accurate depth value is not required. However; if the 20 percent error percentage is unacceptable, there are more accurate methods available, such as Ground Truth and Migration. A known target depth, known as Ground Truth, is the most accurate method to calibrate the depth scale. Any feature identified in the data can be used if its depth is known from an independent source, such as exposed rebar. If the concrete bottom (bottom of slab) is visible in the data, a known concrete thickness can be used if measured at the edge, in a core or known from good documentation. Core drilling is, in most cases, the only way to measure the exact depth to a particular rebar or other structural element.

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

A spot calibration can be applied to the entire structure or a section built with the same concrete. It is up to the analyst to decide how representative the spot value is. If it is not possible to obtain a known target depth, migrating the data by means of hyperbola matching is an alternative for depth measurement calibration. Migration calculates the signal velocity in the medium from the shape of hyperbolic reflections. By matching an animated hyperbolic shape to the GPR data, the system is able to measure the velocity of the signal and recalculate the depth scale. Migration is only accurate if you scan perpendicularly across the target, as the shape of the hyperbola will change if the target is not scanned perpendicularly. Migration is becoming a standard in depth calibration. An added benefit is that this process eliminates hyperbolas by collapsing them into dots representing the actual targets. This can be helpful to make target identification more intuitive. Migration can reduce clutter in the image and make it easier to interpret.

TO CALIBRATE, OR NOT TO CALIBRATE? The accuracy of all measuring devices, including GPR, change over time. This is typically caused by normal wear and tear, damage, etc. However, changes in accuracy can also be caused by factors related to the survey environment, such as concrete surface or age. Depending on these factors, there is no specific schedule related to calibration needs, as frequency may change. Understanding your GPR system will help identify when and how often you should consider calibrating it. Each equipment manufacturer will outline calibration techniques in their user manuals.

The Business of Business

What to Expect from OSHA in 2016 and Beyond By Mark A. Lies, II, Patrick D. Joyce and Adam R. Young

he New Year is here and with that comes yet another year of enhanced OSHA enforcement and new OSHA regulations. Further, due to the upcoming end of President Obama’s time in office, questions exist as to whether OSHA will continue with its aggressive agenda of enhanced enforcement with increased citations and greater penalties or whether OSHA will respond due to political pressure from the Congress. In either case, this year will bring new levels of uncertainty with the agency that we have not seen since the current Administration took office in 2009. This article will address OSHA’s current and upcoming enforcement initiatives and trends, all of which will affect employers in the coming year. OSHA’S ENFORCEMENT INITIATIVES Though a number of OSHA’s enforcement initiatives may not technically be considered new for 2016, we can expect that OSHA will continue to increasingly issue citations under the General Duty Clause and the multi-employer worksite doctrine. We can also expect OSHA to continue to focus its attention on the training and protection provided to temporary employees, especially under OSHA’s Powered Industrial Truck (forklift) standard, Personal Protective Equipment (PPE) standards and Lockout Tagout (LOTO) regulations. OSHA has also been stepping up its workplace heat illness initiative, sending expansive subpoena requests to dozens of employers engaged in industries where employees typically are potentially exposed to heat, including manufacturing and construction, even if no injuries or illnesses have been reported. As such, it is important that employers remain aware of these issues to try to limit liability in 2016.

INCREASED USE OF THE GENERAL DUTY CLAUSE

INCREASED OSHA PENALTIES The new bipartisan budget, passed by both the House and the Senate and signed by President Obama on November 2, 2015, contains provisions that will raise OSHA penalties for the first time in 25 years. The budget allows for an initial penalty “catch up adjustment,” which must be in place by August 1, 2016. The maximum initial “catch up adjustment” will be based on the difference between the October 2015 Consumer Price Index (CPI) and the October 1990 CPI. The October 2015 CPI was released on November 17, 2015, and came in at 237.838. Based on the October 1990 CPI of 133.500, the maximum catch up adjustment will be approximately 78.16% and the new maximum penalties could be: Current August 2016 Other than Serious violations Serious violations Willful violations Repeat violations

4 2 | M ARC H .16

After the initial catch up adjustment, OSHA will be required to implement annual cost of living increases, with the adjustment tied to the year over year percentage increase in the CPI. Adjustments must be made by mid-January each subsequent year. OSHA has the option to implement a catch up adjustment less than the maximum if the Agency determines increasing penalties by the maximum amount would (1) have a “negative economic impact” or the social costs of the increase outweigh the benefits and (2) the Office of Management and Budget agrees. However, Assistant Secretary of Labor for Occupational Safety and Health Dr. David Michaels has long advocated for a substantial increase in penalties so it is difficult to envision the Agency seeking anything other than the maximum increase.

$7,000 $7,000 $70,000 $70,000

$12,471 $12,741 $126,000 $126,000

Under the Occupational Safety and Health Act’s General Duty Clause, designated as section 5(a)(1), employers are required to protect employees from recognized workplace hazards that are correctible and likely to cause serious harm or death. Where OSHA lacks a specific standard to address a workplace hazard, the Agency has increasingly used the general duty clause as a “gap filler” for enforcement. OSHA thus has used the General Duty Clause to cite employers for a wide range of alleged hazards, including the following items, and to enforce policies the Agency issued through guidance documents rather than formal regulations. • Ergonomics • Illness due to exposure to heat and cold • Arc flash/arc blast • Combustible dust • Chemicals and other hazardous materials for which there is no existing regulation • Fall protection

This year, we expect that the Agency will use the General Duty Clause to cite employers for repetitive tasks causing ergonomic issues and musculoskeletal disorders. Moreover, in light of the increasing publicity given to the hazard because of tragic incidents involving workplace shootings, OSHA will continue its emphasis on citing employers for workplace violence incidents and violations, particularly in certain industries such as healthcare, certain retail facilities and public transportation such as taxi cabs. Employers should maintain policies and training on these issues to prevent liability and business disruptions from OSHA’s increased use of the General Duty Clause in 2016. OSHA TO REDUCE RELIANCE ON PERMISSIBLE EXPOSURE LIMITS In a move that could drastically affect day to day operations at a large number of employers, OSHA has signaled in a new permissible exposure limit (PEL) request for information from industry and other stakeholders that it plans to “revoke a small number of obsolete PELs.” Though the rulemaking did not list the PELs OSHA is considering revoking, the revocation of any PELs opens the door for greater use of the General Duty Clause to regulate employee exposure through standards that are not generally industry standards such as NIOSH standards or ACGIH recommended exposure limits. Several commentators believe the PEL walk back is simply OSHA’s attempt to increase employer liability for more citations while avoiding formal rulemaking to establish PELs. Combined with higher fines to be implemented by August, 2016, this could be seen as a new revenue stream for OSHA. NEW SILICA RULE EXPECTED TO BE RELEASED BY JANUARY 2017 Crystalline silica particles are commonly dispersed in the air when workers cut, grind, crush or drill silica-containing materials such as concrete, masonry, tile and rock. OSHA estimates that 2.2 million American workers are regularly exposed to respirable silica, with 1.85 million of those workers in the construction industry. Other common sources of exposure are building products manufacturing, sandblasting and hydraulic fracturing (fracking) of oil and gas wells. Crystalline silica exposure can cause lung

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

cancer, chronic obstructive pulmonary disease and silicosis, an incurable and sometimes fatal lung disease. OSHA has outlined a new Silica Rule as a top priority since the beginning of the Obama administration. The Agency sent a draft rule to the White House Office of Management and Budget (OMB) in February 2011, and has pledged to release a final rule by January 2017. (See the notice of proposed rulemaking at https://federalregister.gov/a/2013-20997).

OSHA’s Silica Rule will establish permissible silica exposure limits for all workers at 50 micrograms per cubic meter of air, cutting allowable exposures in half in general industry and maritime businesses, and even more in construction. The proposed rule also includes preferred methods for controlling exposure— such as using water saws to reduce airborne silica dust. The rule will also require that employers conduct periodic air monitoring, limit workers’ access to areas where exposures are

C O N C RET E O P EN I N G S | 4 3

The Business of Business high, enforce effective methods for reducing exposures, provide medical exams for workers who have been exposed to elevated levels of silica and require training for workers about silica-related hazards. FINAL IMPLEMENTATION OF NEW GLOBALLY HARMONIZED SYSTEM (GHS) STANDARDS OSHA adopted new HCS 2012 SDS standards on December 1, 2013. Chemical end users must come into compliance with the new SDSs passed down from up-stream suppliers and manufacturers by June 1, 2016. Employers should not simply swap in a new SDS for an old MSDS and throw away the old MSDS. Previous MSDSs should be kept on file for the following reasons. • It should provide proof that an employer was compliant with 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 and • 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 SDSs also presents an opportunity for employers to update their 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. When OSHA begins enforcement against employers on June 1, 2016, it will focus on whether the employer 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. The Hazard Communication Standard affects nearly every employer, from chemical manufacturers to retailers to hotels whose employees work with cleaning agents. Employers need to be aware of their obligations to communicate hazards of chemical substance, and must have a process for updating existing labels, SDS, hazard assessments and training programs to comply

continued

with HCS 2012. Here are some best practices for employers to follow. • Employers should review the new SDSs in a timely fashion upon receipt. • If the employer does not receive the SDSs in a timely fashion, it should promptly communicate in writing with the manufacturer to obtain the SDSs. If the employer does not receive the SDSs by June 1, 2016, OSHA has indicated that it will not cite employers who show “good faith efforts” to obtain the SDSs. • Employers should evaluate the workplace using the SDSs to identify hazardous chemicals and how their employees may be exposed. • Employers whose employees work with or around hazardous chemicals must ensure that they review the updated SDSs and assess each of the employer’s underlying compliance programs (e.g., emergency action plan, storage of flammable and combustible materials, PPE, respiratory protection, etc.) that may be impacted by the SDSs. • Employers should ensure that employees who work with or around hazardous chemicals are trained to recognize the pictograms and hazard warnings that will be required under the new Hazard Communication Standard. Employers should document this training and develop mechanisms to ensure that employees understand the hazards of working with or around hazardous chemicals. MIDNIGHT REGULATIONS AND INTERPRETATIONS As with any outgoing administration, there is always the potential for “midnight regulations,” often implemented through rulemaking in the waning days of an Administration, particularly after an election. Though President Obama will not leave office until January 20, 2017, employers should prepare for last minute regulations or potential “executive orders” that may have lasting effects on employers. For example, under the Clinton administration, OSHA issued an ergonomics rule shortly after the 2000 election and Congress was forced to repeal the rule shortly after President Bush took office in January 2001. The likelihood of midnight regulation under President Obama depends heavily on which party wins the presidency in November 2016. To avoid potential political fallout for

a new administration, OSHA will likely implement any new regulations as early as possible in 2016. Midnight regulations are not the only potential consequence of an outgoing administration. New last minute interpretations of existing regulations and guidance could also have a significant impact on employers. While the Eighth Circuit’s ruling in Loren Cook Company, discussed above, may lessen the likelihood of drastic reinterpretations of rules, employers should still be on the lookout for changes in interpretation and implementation that may affect how companies do business. The first seven years of the current Administration have been very challenging for employers under OSHA and other employment laws. 2016 may be the most challenging as the current Administration wants to project its agenda in the waning days of its authority. The President has said that in his last year he intends to “leave it all on the field” as to his agendas which means that employers must continue to be vigilant, keep informed and respond properly.

Diamond Products Introduces First-CutTM Early Entry Saw The CC148XL-EE First-CutTM saw from Diamond Products is part of the True Early Entry SystemTM designed for early entry cutting. This lightweight, walk-behind saw has a spring loaded skid plate guard that keeps the skid plate down on the green concrete, thus preventing spalling. With a 6-inch blade capacity, the maximum cutting depth is 1.188 inches. The blades turn in an up-cut direction to keep debris out of the cut line. The blade is lowered into the cut with a raise and lower mechanical system with spring loaded release. A unique structural feature is the telescopic handle that adjusts to the operator’s height. This can help the operator when cutting long passes. Additionally, the saw frame is a heavy-duty steel that prevents damage during transport. This saw also has five wheels under the frame for increased stability and prevents the saw from wobbling during cutting. With a Honda GX160, 4.8-horsepower gas engine, the CC148XL-EE FirstCutTM saw is well suited for the green concrete cutting industry.

Construction Industry Safety Coalition (CISC) Update Representatives of the CISC met with the Administration’s Office of Management & Budget (OMB) on February 1, 2016 regarding the implementation of OSHA’s Proposed Rule on Occupational Exposure to Crystalline Silica. The CISC focused on three themes during the meeting: •

•

The construction industry presents unique challenges with respect to compliance with any crystalline silica rule. Silica is ubiquitous on construction sites and is, thus, like no other health substance OSHA has regulated for construction. The prevalence of multi-employer worksites also presents significant challenges to construction employers and makes overall compliance with any rule extremely difficult. The proposed rule did not appreciate the unique aspects of construction. With the exception of one table in the rule, OSHA simply took the general industry rule and applied it to construction, which is considered unworkable. Furthermore, the table was not a true safe harbor and was drafted such that no construction employer would avail itself of that limited compliance option. The rule is technologically infeasible. OSHA has not shown that the proposed PEL of 50 (with an AL of 25) can be met in “most” construction operations “most of the time.” The assumptions that OSHA uses in asserting the PEL is technologically feasible are not the best available evidence and do not reflect real world construction conditions. Finally, NIOSH testified that in order for a construction employer to be assured of compliance with a PEL of 50 – due to the unique and variable conditions on construction worksites – the employer would actually need to control silica exposures to a level at or below the AL. OSHA has not come close to making that showing.

5 4 | M ARC H .16

•

The rule is economically infeasible. OSHA has made several incorrect assumptions about the make-up of the construction industry, the distribution of controls, and other data inputs that has severely underestimated the costs of the rule. For feasibility purposes, OSHA analyzed the profitability of the construction industry before the recession, which does not reflect the economic reality of today.

OMB was definitely interested in aspects of the rule that the CISC would support and what changes to the rule the CISC would view favorably (and potentially cause it to support the rulemaking). As has been discussed with CISC members, OSHA was told that the coalition had thought long and hard about this, but there were so many issues with the proposed rule that it was difficult to identify any particular change that would make the rule palatable or address the unique aspects of the construction industry. CSDA is a member of CISC and joined the coalition to provide a unified voice from the construction industry on OSHA’s Proposed Rule on Occupational Exposure to Crystalline Silica. CISC is comprised of 25 trade associations representing virtually every aspect of the construction industry. A copy of the proposed rule can be viewed via www.osha.gov/silica.

ST-115 CERTIFICATION This certification is the first of its kind for measuring concrete surfaces and their surface texture value. The approach is to measure and analyze the surface texture in order to understand how the texture is influenced by the finishing process, and how the surface texture influences its behavior with regards to gloss, friction and sustainability. The certification is based on Standard CSDA-ST-115.

A CERTIFIED OPERATOR: • Has been provided instruction on how to correctly measure concrete micro surface texture • Has knowledge of proper tool selection to mitigate damage • Passed a written test • Was issued a certificate upon completion of the class For more information about this Standard, certification or a list of current ST-115 Certified companies, visit www.csda.org/st115.

TESTIMONIAL Like many operators in the industry, I was largely self-taught but wanted to figure out if I was doing everything right. It was 10 years ago that I met some CSDA members at World of Concrete and I started to look on CSDA’s website for training and member resources. I joined the association soon after and returned to World of Concrete in 2010 to take part in the association’s first training class at the show – a Wall Sawing 101 class. Since then, my son, Ben, and I have completed more training classes and are Jack Doherty Jack Doherty Contracting, LLC both now CSDA Certified Woburn, Massachusetts Operators for slab sawing, jack@jackdohertycontracting.com core drilling and wall sawing. Aside from the training, I have found CSDA to be a wonderful organization for networking and learning from other members. Any time I have called someone for advice or recommendations, my fellow members can’t do enough to help. That is truly a great benefit.

THE CSDA WEBSITE AT WWW.CSDA.ORG CONTAINS A WEALTH OF INFORMATION AVAILABLE 24/7 IN THE “MEMBERS” SECTION. IN ADDITION, CSDA’S FACEBOOK PAGE AND DISCUSSION FORUM GROUP PAGE ALSO PROVIDE MEMBERS WITH A CHANCE TO DISCUSS TECHNICAL ISSUES, SELL EQUIPMENT, HIRE EMPLOYEES OR ANY OTHER RELEVANT TOPICS.

Director’s Dialogue

CSDA: The Last and Next 25 PATRICK O’BRIEN Executive Director

n late 1991, I had the honor of being appointed executive director of CSDA after a decade with GE Superabrasives. The other day someone asked me how has CSDA changed over the years? Perhaps this is a good topic to address here for Concrete Openings readers. CSDA membership stood at about 200 member companies back then and today is nearly 500 companies. More than doubling our membership is pretty good, but what attracted those companies to join CSDA? Membership value is what attracts people to any association. When I first started with CSDA, the Board wanted to grow membership and said, “Pat you know a lot of people, so why don’t we pay you to bring in new members?” My response was yes, I might be able to convince people to join CSDA. However, if there was no real value in them joining then they might join for one or two years and then leave. What we needed to do was create value so that a company could join and remain a member for some time. We started creating member programs, with a focus on training and safety, but an executive director could not do it all. So we instituted a committee structure that today is the envy of the association industry. The dedicated committee members helped to create value for members. Today, CSDA offers safety manuals/handbooks, videos, Toolbox Safety Tips and standards/ specifications/best practices that have reached thousands of members, prospects and specifiers. The number of training graduates from the association’s classroom, hands-on and online courses is near 5,000. While that is quite an accomplishment, committees are working hard to further the acceptance of these programs and materials.

6 4 | M ARC H .16

These benefits required funding and annual membership dues that totaled less than $100,000 in 1991 to nearly $400,000 today have certainly helped. The overall budget has grown ten times to over $1 million. These additional funds have allowed CSDA to accomplish many other programs on behalf of the association. These include outreach with OSHA through an Alliance program, challenging the Silica Rule, marketing the association and its services to the specifying community as well as international cooperation through the creation of, and participation in, the International Association of Concrete Drillers and Sawers. CSDA has turned the annual World of Concrete exhibition into a major outreach effort for the association. CSDA actively promotes this event and in addition to the publicity we receive, the association has collected half a million dollars in cosponsor rebates for these efforts. These funds help to develop even more programs to create value for members. The association has come a long way, but the future is even brighter. Many of the pioneers that were responsible for getting CSDA launched have, or soon will, retire. The Next Generation group is bringing in new leaders with new ideas as the association grows in different ways than it did for the pioneers that came before them. CSDA has been a success, but I venture to predict that the future will be even brighter with the younger generation stepping into leadership roles. I thank you for your support of CSDA and know that we will achieve great things going forward. Did you learn anything, or was this just another story from an elder statesman of the industry?

Go ahead, polish a floor by hand. Introducing the new PG 680 RC remote controlled planetary grinder. The PG 680 RC is a remote controlled version of the popular dual drive PG 680, and is also equipped with a unique oscillation function. The oscillation function enables the best possible grinding pattern and a flatter floor by eliminating ridges created between passes. The operator can adjust the amplitude and frequency on the remote to tailor grinding and achieve optimal results on different surfaces. Using a remote controlled grinder increases production, as the grinding parameters can be maintained over a longer period of time. This also leaves the operator with more time to prepare for the next steps in the grinding process or move other equipment without having to stop grinding.
