JACK SONDERGARD CSDA President

I

am honored and humbled to be considered, nominated and elected as the new President of CSDA. This is an organization filled with dedicated contractors, manufacturers and other industry specialists. These people give their time and energy to improving and advancing the training, techniques and tools of our focused industry segments. I pledge to work diligently with the Board of Directors to continue CSDA’s progressive path as a recognized leader in our industry.

I began as a concrete cutter during the summers as I attended UW-River Falls, seeking a degree in business. Eventually, I was working more as a cutter and less as a student. At the time, my employer, David Lessor, was President of CSDA and instrumental in developing its training program. I was in one of the first ever CSDA training classes.

I remained a cutter for 18 years until I moved to central Wisconsin to open my own company in 1997.

I immediately joined CSDA and began attending the annual convention. I learned so much during these conventions that I quickly determined that my business and my employees would benefit from further involvement with this organization. I started attending quarterly meetings. It wasn’t long before I was serving on the Safety Committee, eventually chairing it, while serving on a handful of others. I was then elected to the CSDA Board of Directors in 2008.

Safety has always been a number one priority for CSDA and my top priority as a business owner. I knew the key to safety was proper training. I sent my first employee to CSDA training and eventually he became a Certified Operator in all concrete sawing and drilling disciplines. I continue to send employees to various hands-on CSDA courses and now have employees participating in the association’s online courses too.

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

For years, CSDA had a working alliance with OSHA to cooperatively address safety improvements in our industry.

Our goal was to educate and show how Best Practices written and endorsed by CSDA could help cutting companies provide safe work environments for employees. The recently-released Final Silica Rule remains a challenge and the association will continue to help members comply with the new regulation and look for ways to change it.

In an effort to elevate our industry, the CSDA Company Certification program will remain robust. We have an outside administrator currently reviewing documentation to certify CSDA companies. Contractors will be asked to provide company policies and procedures relating to safety practices, equipment maintenance, verification of training, insurance record keeping and compliance with existing laws. The certification program validates companies, raises the professionalism and profile of members to the wider construction industry and gives more value to the CSDA brand.

As your new President, I am excited by the direction our organization is heading. I look forward to the challenges ahead. We have an experienced Board of Directors who share my passion for our industry. I am grateful to all the manufacturers who support our organization through donation of their valuable time and expertise while serving on various committees and the Board.

Quarterly meetings are open to all prospective and current members. The information available is immediately useable and valuable. Please check out our schedule and join us whenever possible. I look forward to seeing you at a meeting soon.

The 564-space, five-story parking garage had fallen into disrepair.

Aging Parking Structure Refurbished Using Diamond Tools A deteriorated 564-space, five-story parking garage in the busy center of downtown Columbus, Ohio, has been given a new lease on life with help from a professional concrete cutting contractor.

To allow the structure to be safe and fully-functional once more, the contractor performed over 750 feet of horizontal and inverted wall sawing on the garage’s 10-inch-thick concrete deck slabs and created 64 beam pockets to allow the installation of new steel reinforcing I-beams. In addition, a number of openings were made using core drills for the installation of plumbing lines and utility ducts.

The parking garage, located at 56-62 Long Street, was closed in September 2013 by the City of Columbus due to structural problems.

Built in 1954, it had been reported that concrete from the garage was breaking off from overhead beams and bowed deck slabs and falling on cars parked below. Previous plans to refurbish and reopen the garage

had failed, and it had remained out of service since its closure.

Then, in early 2016, the garage was acquired by Connect Realty with a plan to become part of a larger redevelopment scheme.

The new owners had already acquired two buildings nearby and plans were underway to convert the spaces into “microliving” apartments—a mix of one-bedroom, studio and small apartments ranging in size from 300 to 870 square feet of living space—along with street-level offices and storefronts. Realizing that parking options were limited around the properties, the developers moved to purchase the parking garage. The plans for the structure included the installation of glass windows on two sides, the addition of heating systems for the upper levels, the conversion of the ground floor to management offices and the addition of an on-site car wash and valet service. Before these plans could become a reality, however, the garage had to be structurally sound.

General contractor Mid Ohio Contracting Services, Ltd. of Columbus needed to find a specialty concrete sawing and drilling company that could create the required beam pockets and deck slab cuts on the waning structure with high precision and low vibration. The job was awarded to CSDA member Donley Concrete Cutting Co. of Pickerington, Ohio.

A series of 64 beam pockets were required to house new reinforcing steel framework.

A custom mount was fabricated to secure the wall saw to the concrete structure.

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

“This job was not going to be without its challenges,” said Donley Concrete Cutting operations manager Jason Young. “The specifications we were given had tight tolerances. The steel framework was prepared and fabricated off-site and needed a precise layout so that each component would connect together. Methods like jackhammering had been ruled out prior to us winning the job due to a lack of accuracy and excessive vibration, but even hand sawing the pockets was not going to be accurate enough. Therefore, we chose track-mounted wall sawing techniques. This gave us the precision and sawing speed, but the setup and takedown for each cut was going to take time we didn’t have.”

The cutting contractor had been given four weeks to complete all sawing and drilling tasks, so the focus turned to streamlining the setup and takedown process of the wall saw. Donley Concrete Cutting fabricated a rigid floor mount for the saw and customized a gear rack setup to move it from one cut location to the next. This allowed the operator to perform multiple cuts from each mounted setup. The saw was anchored to the slab and leveled before cutting began. For both the horizontal and inverted cuts on the garage’s deck slabs, the notches created had to be level so that the steel beams sat correctly. Most of the parking deck slabs were bowed in one direction, so the contractor had to make slight adjustments as necessary.

For the 2-inch-wide, 5-inch-deep beam pockets, the wall saw operator performed each cut from inside a man lift while an assistant would stay on the slab to hand crank the saw to each of the 64 cut locations. Both employees were tied off and wore the appropriate PPE for the job.

A Pentruder 8-20 high frequency wall saw fitted with a 32-inchdiameter blade supplied by Diamond Tools Technology was employed to complete the cutting work. Mounted to the contractor’s customfabricated gear rack, the operator and assistant made four individual cuts off one setup with the saw. After each pocket was created, the pair would reset the saw at the next location and repeat the procedure for all 64 pockets. This took approximately two weeks. Thanks to the ingenuity of the cutting contractor, only 64 track-mounted setups were required to complete the pockets instead of 256—one for each individual cut.

Next, Donley Concrete Cutting made a series of horizontal and inverted wall saw cuts on each deck slab face, which were performed using traditional mounting and sawing techniques. The inverted cuts were done with the operator a safe distance away in the man lift, operating the saw by remote control. Each 100-foot section of cutting took one day to complete. The diamond cutting work left a smooth, clean finish for the general contractor to install its steel channels.

The contractor completed 774 feet of horizontal and inverted cutting on the garage’s deck slabs.

“Many of the specified cut locations had us sawing through existing steel reinforcing rebar in the parking garage slabs and these locations could not be moved. However, this proved to be little problem for the saw’s rigid mount setup and the power we got from the Pentruder system,” explained Young.

With all sawing work completed for the rehabilitation and strengthening of the deck slabs, the cutting contractor turned its attention to the sawing and drilling of duct and utility openings.

Operators created eight 36-inch square and four 25-inch square duct openings in one week using the Pentruder wall saw and an ICS chain saw to eliminate overcuts. In addition, 50 core holes measuring 9 inches in diameter were made for floor drains. The contractor employed a Hilti DD 350 core drill for these openings, which were completed floor-by-floor as needed by the plumbing contractor on site.

Each beam pocket consisted of two 2-inch-wide by 5-inch-deep slots.

Refurbishment of the Long Street Parking Garage will provided muchneeded parking space for the residents of nearby apartment conversions.

Over the course of two months, Donley Concrete Cutting completed 387 feet of horizontal wall sawing in the face of each parking deck slab followed by 387 feet of inverted wall sawing on the bottom. These cuts successfully created space for steel channels to be fitted. Also, the contractor made 64 beam pockets that consisted of two 2-inch-wide by 5-inch-deep openings in the 10-inch-thick concrete deck slab. The use of diamond tools and equipment, coupled with the custom-fabricated mount, enabled the cutting team to complete all specified tasks ahead of schedule and within budget. Young gave his final thoughts on the job. “I was ecstatic with the outcome of this job.

It required us to come up with innovative practices to complete the necessary cuts in a safe and streamlined process,” he stated.

The CSDA member’s work was completed between January and March 2017 and the refurbished parking garage on Long Street should reopen later in the year, providing much-needed parking for residents and workers of downtown Columbus.

Zack Forster, supervisor with Mid Ohio Contracting Services, said, “Donley Concrete Cutting did an exceptional job! The team performed well and did everything they were asked to do, finishing ahead of schedule. The guys were very easy to work with, which made this portion of the job go very smooth.”

COMPANY PROFILE Donley Concrete Cutting Co. has been a CSDA member since 2004 and is based in Pickerington, Ohio, with a support location in Cincinnati. The company has been in business for 20 years.

A POLISHED EDUCATION Surface Preparation Contractors Go Back to School

Contractors installed polished floor systems in three Kansas school buildings.

12 | JUNE.17

Two professional surface preparation and floor polishing contractors joined forces when faced with an outstanding, yet very challenging opportunity that exceeded either of their individual capacities.

Together, they not only completed the project under time and under budget, their high-quality workmanship delighted the client and yielded an award.

The floor preparation professionals were charged with polishing large floor areas in three separate school buildings to a 3,000grit finish, covering a combined 40,000 square feet. The existing canvases were a challenge given their 20+ year age, condition and irregular layout. The limestone aggregate floors in some areas required the use of professional grade grout filler to repair cracks and other openings. Being school buildings, there were dozens of different doorways with lots of challenging crevasses and awkward spaces between walls and columns that had to be polished by hand.

Jessica Ledger-Kalen, owner of CSDA member Royale Concrete based in Fairfield, Iowa, and Mike Denny, owner of Artistic Concrete Surfaces, LLC (ACS) in Spring Hill, Kansas, had no idea that a friendship forged at a CSDA-ST-115 (Measuring Concrete

The old floor coverings had fallen into disrepair, so they were removed and replaced with polished surfaces.

Micro Surface Texture) Certification course would manifest itself in the development of a partnership that has resulted not only in profits, but in industry praise.

“Mike and I hit it off during the ST-115 Certification course because we both shared common values as employers and experienced concrete contractors,” said Ledger-Kalen, a CSDA Board member and chairperson of the association’s Polishing Committee. “Our goal at Royale Concrete is to only accept jobs for which we are one-hundred percent confident we can deliver outstanding quality and service.

Royale Concrete’s focus is absolutely about customer satisfaction and I could tell that both companies were grounded with the same foundation.”

The two identified the opportunity to work together on the large, multiplebuilding concrete polishing contract for the Blue Valley School District in Kansas.

It was a great chance to capitalize on their relationship and combined company assets to do something that neither could have taken on alone.

A structured floor preparation system was used to achieve a 3,000-grit finish.

“I grew up in the Blue Valley school system and had been working with the schools for some time to convince them that polished concrete was the best flooring solution,” commented Denny. “When they invited us to bid on a bigger, multi-school job, I recognized that while we couldn’t do it alone, we could pool resources with Royale Concrete to successfully complete the work on time and to their high quality standards.”

The Blue Valley job design and specifications included difficultto-meet standards, multiple general contractors and a tight timeline.

The team worked closely with the architect to find a way to achieve the results while building a relationship with both the architect and the school system—managing expectations for future projects. The team also worked with representatives from Husqvarna Construction Products and the manufacturer’s specifications to get all parties on the same page.

Operators implemented Husqvarna’s HiPERFLOOR® concrete surface polishing system, mechanically refining the already hard concrete surface through a process of grinding, polishing and chemical treatments. The floors were specified based on their level of sheen and

aggregate exposure using an established industry standard.

Work began with the use of bush hammer tooling, which was applied as a test to expose large aggregate quickly in line with the customer’s preference. The bush hammering was a success and provided the right type of surface for the contractors to move through a progression of metal grinding steps.

Next, a series of transitional tooling was applied by the contractors.

The careful progression of each tooling step allowed the operators to reach the floor’s maximum level of refinement with a 3,000-grit finish.

The floor presented inconsistently with different degrees of porosity throughout the floor and several tight obstructions, which made it difficult to expose large aggregate in all areas. The contractors used a GM3000 grout filler from Husqvarna, filled joints with Versaflex SL 75 and used Versaflex tinted mender to fill small repairs, as well as cementious repair using rapid set cement. Corner polishing was extensive with doors and many angles through the project.

Collaboration wasn’t always easy, but the trick, Ledger-Kalen explained, was that both parties had a clear understanding from the start about roles and responsibilities. Royale Concrete accepted the project

planning role and conducted weekly meetings with ACS to be sure everyone was aware of each other’s efforts and that the project was on schedule. The companies pooled resources to procure materials in order to get the best deals and dispatched employees on a schedule that enabled both companies to continue running other smaller individual projects simultaneously.

“We acted as one company,” Ledger-Kalen explained. “There was never a feeling of competition, quite the opposite in fact. We deployed workers, ordered materials, tracked expenses and divided profits as one entity from the start. Not only did we accomplish more by working together, we also learned a lot from one another. Our employees enjoyed working together and we truly feel that both companies have been strengthened from this effort.”

Upon project completion, ACS applied for and was awarded a 2016 Polished Concrete award from the Concrete Promotional Group of Kansas City. “My team was incredibly proud of the high quality results we achieved at Blue Valley,” Denny said. “We were excited to showcase our work, and that of our Royale Concrete partners. We hope to be an example to others to demonstrate that competitors can truly work together to accomplish outstanding results.”

“I have a great deal of respect for Mike and his team,” LedgerKalen said. “We’ve created a good partnership and I’m confident we’ll continue to build on that in the future.”

COMPANY PROFILE Royale Concrete has been a CSDA member for two years and is based in Fairfield, Iowa. The company has been in business for 11 years. It has 10 employees and offers the services of surface preparation, polishing, coatings, urethane concrete and floor repair. Royale Concrete employs operators that are CSDA-ST-115 Certified.

OSHA’s Silica Rule Delay— An Opportunity to Better Prepare

By Kellie Vazquez The information in this article was originally presented as part of the panel discussion OSHA’s Final Rule on Silica—How to Prepare Your Company during the CSDA 2017 Convention & Tech Fair in March.

B

y now, most reading this will be aware that on April 6th the U.S. Occupational Health & Safety Administration (OSHA) delayed its enforcement of its Final Rule on Respirable Crystalline Silica by 90 days. This means everyone now has until September 23, 2017 to prepare.

The hope is that all in the concrete sawing and drilling industry are ready for the implementation of this new rule, but if that is not the case then this article may help to further clarify what the rule entails and offer some guidance on how to prepare for the new enforcement date. First, it is worth revisiting the basics of this new rule and addressing frequently asked questions.

•

THE NEW RULE

Q: WHAT IS TABLE 1?

•

A: Table 1 is part of OSHA’s Final Silica Rule.

It consists of 14 common construction tasks and their approved dust control methods and respirators usage. Employers must fully

Reduces Permissible Exposure Limit (PEL) to 50 micrograms per cubic meter calculated as an 8-hour timeweighted average (TWA)

Final Silica Rule—The Timeline

20 | JUNE.17

Reduces Action Level (AL) to 25 micrograms per cubic meter calculated as an 8-hour TWA

Q: AM I COVERED BY THE NEW RULE? A: All occupational exposures to respirable crystalline silica in construction work are covered, unless employee exposure will remain below 25 micrograms per cubic meter of air as an 8-hour TWA under any foreseeable condition—a situation that can be reasonably anticipated. The two ways of determining exposure levels are: • A review of the rule’s Table 1 and implementation of its suggested engineering controls • Conduct exposure monitoring

implement the engineering controls, work practices and respiratory protection specified when engaged in a task identified in Table 1.

Employers who fully implement the controls do not have to comply with the PEL or conduct exposure monitoring. A copy of Table 1 can be downloaded from www.csda.org/silica along with other helpful resources.

Q: WHAT IF I DON’T USE TABLE 1? WHAT ARE MY OPTIONS? A: Ensure that exposures are below the PEL, conduct an exposure assessment and ensure methods of compliance are in place. If a company does not have any of this set up, do not wait until September 23rd to implement.

Devise and test plans as soon as possible.

Q: HOW DOES THE EXPOSURE MONITORING WORK? A: The employer must assess the exposure of each employee who is or may reasonably be expected to be exposed to RCS at or

above the action level 25ug/m3 in accordance with either the performance or the scheduled monitoring option.

• Performance Option–The employer must assess the TWA of each employee on the basis of any combination of air monitoring data or objective data that accurately characterizes employee exposures to RCS. Employers must conduct monitoring before work begins, reassess testing whenever there is a change in production, process, control equipment, personnel or when work practices may be expected in a new higher exposure. Objective data must demonstrate employee exposure to a particular task, must reflect workplace conditions and must reflect the exposure on each shift for each job classification and in each work area.

• Scheduled Monitoring Option–The employer should perform initial monitoring to assess the 8-hour TWA exposure of each employee on the basis of one or more personal breathing zone air samples that reflect the exposures of employees on each shift for each job classification in each work area.

Initial monitoring results: Below the AL – no additional testing necessary At or above the AL – repeat exposure monitoring within six months Above the AL – repeat exposure monitoring within three months Repeat exposure monitoring. If it is below the AL, discontinue monitoring only when there are two tests below the AL that are seven days apart. Reassess exposures whenever there is a change in production or work practices that could result in a new or higher exposure. The employer must ensure that samples are analyzed by a laboratory that follows Appendix A of the OSHA standard.

Q: WHAT ARE THE REQUIREMENTS FOR NOTIFYING EMPLOYEES? A: Within five working days after completing an exposure assessment, the employer shall individually notify each affected employee in writing of the results of that assessment or post the results in an appropriate location accessible to all affected employees.

Whenever an exposure assessment indicates that employee exposure is above the PEL, the employer shall describe in the written

The 25-foot-diameter steel water tank was cut and removed.

24 | JUNE.17

Cutter’s Calculated Assault Removes Water Storage Tank A hospital in Houston, Texas, required its existing fire suppression system water tank removed. The steel tank was 9 feet tall and 25 feet in diameter with a layer of concrete ranging from 1 to 1.5 inches thick covering the inside surface. The tank was positioned on a 12-foot-tall concrete platform in the basement of the hospital building.

To remove the structure, general contractor Vaughn Construction enlisted the help of a CSDA member and its team of “tank busters.”

The existing fire suppression system water tank at the hospital was originally installed in the 1970s and was due to be recommissioned.

“Typically, a project of this type—outdoors or in an industrial plant— would require the use of acetylene cutting torches or standard diamond blades,” said Ethan Namink of Aggregate Technologies, Inc. based in Houston, Texas. “However, these methods would have produced flames and smoke in the case of the former, and showers of sparks in the latter.

Due to the risks involved, these methods could not have been used in a hospital environment.”

Breaker hammers were used to remove the concrete from the 9-foot-tall tank wall.

A 1.5-inch-thick layer of concrete lined the interior wall.

The roof and wall of the tank were cut using ceramic alloy saw blades.

26 | JUNE.17

The contractor decided to use ceramic alloy concrete cutting blades specifically designed to minimize or eliminate sparks to cut and remove sections of the water tank. An 8-inch-diameter blade was employed and fitted to electric-powered, handheld saws.

Before the sawing and removal began, the team from Aggregate Technologies, Inc. strategically planned the dissection of the tank’s roof from the inside so that the structure would not collapse in on itself while being dismantled—a very real possibility if the contractor had attempted to remove the roof from the outside. This was a particularly challenging task, as there was little room to maneuver inside of the tank. With the roof removed, the team was able to begin the cutting and removal of the wall of the tank.

Operators first used the handheld saw to cut a 4-foot by 4-foot access hole to the interior of the tank. Once inside the structure, the team began the long process of removing the concrete wall and ceiling. Operators proceeded around the circumference with TE 1000 electric breaker hammers supplied by Hilti, Inc., making sure that the pieces broken off were small enough to haul through the access hole and out of the hospital’s basement.

The 1.5-inch-thick concrete layer was removed from the top down as the operators moved around the tank. Then, with the team securely positioned on ladders, the concrete on the ceiling of the tank was removed using the same process, this time working from the middle of the ceiling out. This stage of the work took around 48 hours to complete with two operators.

Once the layer of concrete was completely removed from the ceiling and interior tank wall, the process of sawing the 0.5-inch-thick steel cylindrical structure began. The specialized ceramic blades selected by Aggregate Technologies, Inc., minimized the production of sparks while cutting. The tank roof was shored up with wooden braces, as its structural integrity was being compromised. With only a few feet of clearance, the cutting and removal team carefully sawed the roof section into manageable sections measuring approximately 2 feet by 2 feet. The roof section took 48 hours to cut and remove.

Next, sawing operators worked to take down the wall of the water tank. Working from the top of the tank down, cut sections were created measuring 2 feet by 2 feet so that they could be easily removed from the work area.

This portion of the work took approximately 48 hours to complete.

Cut sections were made small enough to be removed from the work area by hand.

The work area was considered a confined space, therefore all operators were provided with safety training to handle confined space cutting and a hole watch person was assigned. There was also a full-time CPR trained operator on-site for the duration of the work. In addition, a fulltime superintendent was on-site to perform daily toolbox talks and safety training before each shift, helping to make sure everyone understood how to perform the day’s tasks.

A combination of the right tools and expertise ensured that the team of tank busters from Aggregate Technologies, Inc. demolished the hospital’s old fire suppression system water tank efficiently and safely.

“This was the first tank that that I know of that was completely removed without the use of torch or plasma cutters. We were extremely proud to take on this challenge, and to have the trust of the hospital and client and deliver on this job was a great honor,” concluded Namink.

Hand Sawing

IACDS President’s Insight

T

he year is flying by and, for us here in the U.K., no one is complaining about that. These months bring brighter days, better weather and more work. If we are lucky, we may even get two weeks of summer and sunshine to enjoy! There’s no doubt that productivity in our industry rises during the summer months.

Our team—like yours, I am sure—are very professional and trained to tackle any conditions thrown at them. What I find really interesting, however, is that we still have a lack of people coming into the concrete sawing and drilling industry.

Donald Trump won the U.S. presidential election on a ticket of American jobs for American people. From speaking with members of the U.S. association during the CSDA 2017 Convention, however, the issue many now face is not a lack of work, but getting skilled workers to fulfill the roles required.

It was a topic that came up not only with Americans, but with Europeans and others from around the world too. There’s no question that we have the same issue in the U.K.—finding good people remains a challenge and selling concrete cutting as a career to young people is not always easy.

In the U.K., we recently held an Open Doors initiative through Build U.K., where 209 sites welcomed more than 5,000 visitors to give people—especially youngsters—an insight into what happens on a construction site and the myriad of opportunities there are available.

JULIE WHITE IACDS President

Perhaps, at times, we in the industry take for granted the level of skill required and the many different jobs that are on offer, so it was great to be able to see the interest from the public at this event. It is a new initiative and can only help “sell” our industry to our future potential workforce. Through this same scheme, we are also bringing together a plan of action to engage with schools and to present construction to them in a completely new way. This will begin in September, in line with the new school year.

Through IACDS meetings and events, we hope to come up with new ideas for drawing skilled workers to our industry and seeing it as a viable career.

Goodbye Mallet

New Tool-less Drill Bit Introduced at BeBoSa 2017

A

By Michael Findeis

n experienced core drilling operator certainly knows in an instant what the photographer had in mind when taking the picture above. To loosen a stuck drill bit from the motor, there is often only one archaic way to do it and it involves a mallet and two 41-millimeter (1.614-inch) wrenches.

During summer 2010, the national associations of Germany, Switzerland, Austria and the Netherlands held a meeting and unanimously agreed that this cannot be the accepted method for modern diamond drilling technology, especially as more powerful engines are being introduced to the industry.

The new six time polygon thread.

32 | JUNE.17

The commonly-used 1.25-inch unified coarse (UNC) thread is an old U.S. thread taken from the first deep drillings in the mid-twentieth century and had been proven successful in the oil industry. As the thread had been tried and tested, it was applied to the new and upcoming industry of core drilling through drill bits introduced to the market in the late 1960s. This thread design is still in use today.

The initiative of the associations, especially the German association Fachverband Betonbohren und –sägen e.V., was to try and develop a new thread—one that allows for a quick change of core bit.

Motor and core drill separated.

Accessories: a drill bit extension, a six-hole flange and a drill bit socket for screwing into the drill bit tube.

With what was a quite demanding and complex task, the association was directed to the industry’s manufacturers association, the VDMA (Verband Deutscher Maschinen- und Anlagenbau). This association has the majority of diamond tool manufacturers within its membership, and promptly founded a task force to solve the “mallet and wrench” problem and develop a new thread design.

After numerous meetings and a series of tests with many contractors, the task force decided on a system that was presented to the public at the BeBoSa 2017 sawing and drilling trade show, held March 23-25 in Germany. Visitors were given opportunity to learn more about this core drilling development and test the new conical six times polygon profile thread for drill bits at the German association’s exhibit booth. Prior to this event, German association

member Michael Findeis of Findeis Betonbohrservice GmbH presented this thread concept to CSDA members during the U.S. association’s March 14-18 Convention & Tech Fair in Puerto Rico.

The advantages of this new thread design are: •

It is easy to loosen the drill bit without using any tools. It provides an ergonomic assembly and disassembly of the drill bit. Both the operator and machine are considered, lowering the risk of injury

•

High levels of torque are transferred easily and without vibrations

•

It has excellent dynamic properties through a perfect concentricity

•

A very short construction with low weight

•

Self-centering

•

There are no hollows, as they are in the thread, so it is easy to clean

While drilling horizontal, the drill bit can be laid on the spindle.

Then both hands are free, and can be used to lock the screw nut.

It is hoped that this new system can be offered by all manufacturers in the industry as a standard connection with their motors. Until this happens, contractors can use a six times polygon adapter for their existing machines. For more information, contact the German association at 49-6151 870956-0, info@fachverband-bohrensaegen.de or visit www.fachverband-bohren-saegen.de.

Attempts to create the trench with traditional demolition methods had resulted in excessive noise and vibration.

Cutting Class

Core Drilling Contractor Gives Lesson in Concrete Removal A general contractor was told “shush� when it attempted to remove a substantial area of concrete from outside the library of a top-ranking university, so it called upon a specialist diamond driller to lead a class on low-noise demolition.

A national utility company, Vital Energi, was faced with the task of breaking out a piece of concrete measuring 8.5 meters (27.9 feet) long, 1.3 meters (4.3 feet) wide and 1 meter (3.3 feet) deep at the South Kensington Campus of Imperial College London, United Kingdom.

The concrete area was a redundant crane base that had been constructed for previous work at the library, and had been covered with paving. The concrete needed to be removed so the utility company could create a trench and install a new gas pipeline for the college and surrounding buildings.

However, when a general contractor removed the layer of paving and discovered the concrete crane base, it attempted to

Stitch drilling techniques were employed around the perimeter of the 8.5-meter (27.9-foot) by 1.3-meter (4.3-foot) concrete trench area.

remove the steel reinforced concrete with an excavator and hammer attachment. This proved to be too loud and caused excess vibration within the college library building, so Vital Energi Utilities contacted the London office of CSDA member D-Drill Master Drillers Ltd. and asked the professional sawing and drilling contractor to find a solution that would keep noise and vibration to a minimum.

Branch manager Jimmy Smith explained, “The heavy excavator was making too much noise and we had to find a way to remove the concrete without causing a disturbance. Using our automatic feed diamond drilling rigs, we came up with a plan to stitch drill the perimeter of the trench. Once these openings and others were completed, we employed bursting techniques to break the concrete into manageable pieces for removal.”

The team from D-Drill arrived at the jobsite and began setting up a rig-mounted unit for stitch drilling to commence. A Hilti 110-volt DD

350 core drill machine fitted with a 107-millimeter-diameter (4-inch) bit was mounted at the location of the agreed start point along the perimeter, and it took the operator approximately one hour to complete one hole to the specified 1-meter (3.3-foot) depth.

D-Drill then continued to work its way around the perimeter of the 8.5-meter (27.9-foot) by 1.3-meter (4.3-foot) concrete trench area, creating 208 holes in total and taking around 120 hours to complete.

The operator’s progress was slowed because of the presence of two mats of steel reinforcing bars, one at the top and one at the bottom of the concrete consisting of T25 and T30 bars. Speed and pressure was adjusted to account for the drilling of steel. Not only was the contractor able to dramatically reduce noise and vibration at the jobsite, but its application of wet cutting techniques made sure the creation of dust and debris was all but eliminated.

Imperial College London Imperial College London is a public research university located in London, United Kingdom. The Royal College of Science, the Royal School of Mines and the City & Guilds College were combined in 1907 to form Imperial College, which today is home to 14,700 students and 8,000 staff. Consistently placed among the top universities in the world, it currently ranks 9th in the QS World University Rankings.

The university attracts undergraduates from more than 125 countries and over 6,100 degrees are awarded by the school every year. Imperial College focuses on the four main disciplines of science, engineering, medicine and business and is renowned for its application of these skills to industry and enterprise. It holds a Silver Athena Swan award, which recognizes advancing women’s careers in science, technology, engineering, math and medicine in academia. Distinguished members of the College include 14 Nobel laureates and two Fields Medalists. Read more about Imperial College London at www.imperial.ac.uk.

Larger 200-millimeter-diameter (8-inch) holes were created so the contractor could use hydraulic bursting equipment.

36 | JUNE.17

With the perimeter stitch drilling complete, the core drill operator from D-Drill then made a series of 200-millimeterdiameter (8-inch) holes in the concrete trench to accommodate the company’s hydraulic bursting head. The operator created pairs of holes spaced 750 millimeters (29.5 inches) apart along the 8.5-meter (27.9-foot) length of the trench in 11 hours, which amounted to 12 holes in total.

The bursting head was inserted and the concrete was broken out. A 3-ton excavator was then used to remove the pieces from the work area and all debris was transported from site.

In total, D-Drill spent 13 days on-site to help create the concrete trench and remove the remains of the redundant crane base. Operators created 208 stitch drill holes and a further 12 holes for the bursting head, all to a depth of 1 meter (3.3 feet). The work was completed on time and within budget. This meant that students in the library were able to continue their studies uninterrupted and the general contractor was delighted with the result.

“Not only was the work completed on schedule, but also without any noise or vibration to disrupt those in the Imperial College Library so we were very pleased with the outcome” explained Mr. Smith. “Our operators were very careful during the stitch drilling portion of the work and kept the trench straight and plumb. The client was very happy with the work we did,” he added.

Professional concrete sawing and drilling contractors are well educated in the fields of industrial demolitions and infrastructure renovations, as this job shows. Experienced cutters learn valuable lessons each day on the jobsite that allow them to complete jobs safely and efficiently.

nchoring is a very important daily task that is probably the most underappreciated part of many jobs. However, failure of an anchorage can have serious consequences so it is important to understand how to select and install the proper anchor for a given application.

Some manufacturers of anchoring systems offer no-cost technical support for selecting the correct type and size of anchor for a specific application, and training on proper installation.

For the temporary anchoring of core rigs and wall saws, there are several variables to consider when selecting the correct type and size of anchoring system. The main variables are: • Base material where the anchor is being installed—concrete, Concrete Masonry Unit (CMU), brick, etc.

• Loads on the anchor Size, weight and geometry of equipment being mounted Mounting orientation (floor, wall, ceiling) • Removability of the anchor Because work typically proceeds as soon as the anchors and equipment are set, mechanical anchors, which can be loaded

38 | JUNE.17

immediately after installation, are more common than adhesive anchors that require time for the adhesive to cure before loading.

Typical mechanical anchors include wedgetype, drop-in (flush-mount), screw and coil anchors. However, some base materials like ungrouted CMU and bricks with holes may not be suitable for mechanical anchors, in which case an adhesive anchor may be needed.

If this is the case, the manufacturer of the anchors should be contacted for assistance in selecting one that is appropriate for the specific application.

Once the correct type and size of anchor is selected, it is very important that it be correctly installed. Always follow the installation instructions-for-use (IFU) accompanying the anchor. Below are some important factors which affect anchor performance.

Select the correct size drill bit. This is typically stated in the IFU. Mechanical anchors in particular require a specific tolerance of hole diameter to work properly. Note that drill bits wear over time and at some point the hole will be too small, making anchor installation difficult-to-impossible and adversely affecting the anchor’s capacity. Some manufacturers

place a wear mark on the flute of the bit to indicate when the bit is no longer drilling a correct sized hole. This does not mean that the drill bit has to be discarded, but it must no longer be used for installation of an anchoring system.

See Example 1 below.

The wear indicator lets the user know that when the mark is worn off, the bit can no longer be used for the proper installation of an anchoring system.

If the wear indicator is worn off, then the anchor may not properly set and not achieve its optimum hold values.

Example 1

Identify the drilling location. Positioning the anchor too close to the edge of the base material, to other anchors or certain locations in masonry, can significantly reduce the anchor’s capacity. Anchor manufacturers have

information available addressing these factors.

If steel is encountered, the drilling process should be stopped and the anchor relocated.

Never attempt to angle the bit to get past the obstruction, as the hole geometry will be compromised.

Drill the hole perpendicular to the base material. The capacity of an anchor is directly related to its embedment. The installer should be sure to know for the anchor being used what embedment is required for the load being applied.

Prepare the hole and install the anchor.

A properly-cleaned hole is important for anchor performance, especially for adhesive anchors. If the installer does not have the specified hole-cleaning accessories, they should not proceed until those accessories are available. Follow the IFU. Once the equipment is positioned on the anchor, it should be torqued to the manufacturer’s specified value. Note that excess torque can damage the anchor. Make sure all equipment leveling is completed before torquing the anchor. Never lubricate the anchor threads.

Special Considerations for Drop-in / Flush Anchors: •

•

•

•

•

Never use a drop-in anchor that is not flush or below the base material surface (and note that a drop-in installed below the surface will have decreased shear capacity).

Use the specified setting tool. If it is worn excessively, damaged or mushroomed, discard it. Mushroomed areas can break off and create a risk of flying schrapnel; and if the small end is shortened, incomplete setting of the plug will result.

Never grind or modify a setting tool.

Always ensure the setting tool is driven until it contacts the shoulder of the anchor to achieve proper positioning of the plug—a plug that is not fully set will reduce the capacity of the anchor.

Use rods that meet ASTM standards for thread size and tolerances.

“Unclassified” rods may have undersized threads and may strip out of the anchor. Periodically check the rods, and discard when the threads are damaged or worn excessively.

Make sure the rod is inserted into the drop-in at least the diameter of the rod (e.g., a 0.5-inch rod must have at least 0.5 inch of thread engagement).

One practice, as long as the plug has been properly set and the threads are

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

undamaged, is to insert the rod until it bottoms out in the anchor, then back it out one 360-degree turn.

So before sawing and drilling contractors set out for a day on the jobsite, a few minutes should be taken to inspect tools and review anchoring steps to ensure a safe and productive day.

This article only addresses some of the factors that affect anchor performance. Always strictly follow the IFU; and if there are any questions or

concerns about the correct installation of anchors, contact the manufacturer.

Intermittent Fasting – Breaking All the Rules

By Erin O’Brien

W

hen was the last time you tried to diet or lose weight? Did it work? Your plan probably went like this – eat a healthy breakfast, eat small meals every few hours, more fruits and veggies, less sweets, exercise and get more sleep. Or, maybe you joined Weight Watchers or NutriSystem and counted calories and points with pre-packaged meals.

Tried any of that and it didn’t work? Let’s see what’s behind Curtain #3.

Intermittent fasting is trending as the new way to lose weight. However, this method has been around for thousands of years in various religions and even longer with our Paleolithic ancestors, who involuntarily fasted based on food supplies. Our genes were likely selected during this time by criteria that favored survival in an environment characterized by fluctuations between periods of feast and famine. Something called “the theory of thrifty genes” states that these fluctuations are required for optimal metabolic function, and can help explain today’s obesity and metabolic disease epidemic due to our decrease in daily physical activity and constant food abundance.

So, what is intermittent fasting and why might it be so helpful in losing weight and improving overall health? And why should concrete renovation professionals care?

Intermittent fasting (IF) is a strategic cycle of caloric intake followed by a period of fasting. During this fast, caloric intake is severely restricted (less than 500 calories) or non-existent (except for black coffee, green tea and in some cases, green juice). There are several variations of IF, ranging from the 16:8 diet (16 hours of fasting followed by eight hours of calorie consumption), to the 5:2 diet (two non-consecutive days per week with a caloric intake of less than 500 calories per day, and the remaining five days have no limitations).

The 16:8 diet is often used as a starting point for anyone wanting to try IF, and most people will skip breakfast (formerly holding the title of “Most Important Meal of the Day”), begin eating at noon and have their last meal before 8pm. I know, I know – doesn’t every health professional and internet article tell you to eat

breakfast to lose weight? Yes, many of them do, but new research shows that eating first thing in the morning may not be necessary to kickstart your metabolism as previously thought.

Breakfast comes literally from “break” and “fast” – breaking your fast. So if you first meal of the day isn’t until lunchtime, lunch is the new breakfast and now your body has all of that extra time to benefit from the effects of fasting (more on those later).

There are other, more rigorous IF diets, including a 24-hour fast twice per week, and three consecutive days of nothing but water and green juice. These diets are better left to those who have experience with IF and have been given the all clear from a medical professional.

WHY TRY IF? If you have experimented with other diets in the past and had limited success, IF may be a better option for you. However, anyone wishing to give this a shot needs to have some serious discipline and a good understanding of what a healthy diet looks like. While some have reported success using IF by eating whatever they want when not fasting, most people will get much better results by maintaining a reasonably healthy diet during non-fasting times. This means lean protein, fruits and vegetables, low-glycemic carbohydrates, healthy fats and limited sugar and processed foods.

Now for the science behind it: when you fast, many of your cells die and stem cells turn on, which starts a regeneration process that gives rise to new, younger and healthier cells.

Fasting also increases fat oxidation, which speeds up your fat loss throughout the day.

This helps you lose weight, but weight loss is

not the only benefit of IF. Studies have shown that IF may decrease LDL cholesterol (or “bad” cholesterol) and inflammation, while improving insulin resistance. Insulin is responsible for regulating your body’s blood sugar levels – high blood sugar levels can make you feel hungry and tell your body to start storing fat instead of burning it. Other proven benefits of IF are postworkout muscle growth and a reduced risk of developing diabetes, cancer, cardiovascular disease and autoimmune disease. Now for the real science nerds out there, we’ll dive into the details of why this all happens. If science isn’t your thing, you can take my word for it and skip to the next part.

Post-Workout Muscle Growth: During fasting, your growth hormone levels increase, which stimulates muscle and bone growth, especially when you add cardiovascular and resistance training into the mix (i.e. weight training, running, interval training, etc.). So not only are you burning calories and building muscle by working out, the IF diet will accelerate what you are already doing.

Reduced Risk of Developing Diabetes, Cancer, Cardiovascular and Autoimmune Diseases: A physiological process within your body called “mammalian target of rapamycin,” or mTOR, is a pathway that regulates the growth and survival of your cells, meaning this pathway helps to decide how quickly your cells age, and their level of health. In addition to building muscle, mTOR also has a significant role in the onset and progression of diabetes, cancer and the aging process, thereby impacting your lifespan. Fasting of any kind inhibits mTOR. Several studies have shown that dietary restrictions increase the lifespan of several different species, including humans, and even lowered the chance of general illness. Fasting also lowers insulin-like growth factor 1 (IGF-1) which delays aging and protects against cancer.

Other studies have linked IF to the brain’s ability to resist neurodegenerative diseases like Alzheimer’s and Parkinson’s, while improving mood and memory. Essentially, the less active your mTOR pathways are, the slower your cells age and can better resist chronic, metabolic, cardiovascular and autoimmune diseases.

I’M IN! HOW DO I START? As mentioned above, the easiest way to start an IF diet is the 16:8 method – choose an eight-hour window to intake all your calories for the day and fast for the remaining 16 hours. Most people find it easiest to skip breakfast (you can still have coffee, tea and water, but no milk or sweetener), then eat a full lunch around noon, snack mid-afternoon if needed and finish with a substantial dinner at the end of your eight-hour window. This is also the best way to avoid any social awkwardness or skipping meals with your family. As to what you eat during the eight-hour window, just follow a smart basic nutrition plan: lean protein, good carbs, fruits and veggies and lots of water. If you find this method works for you, and want to see better results, you can gradually increase your fasting window from 16 hours to 18 and then a full 24, followed by two to three days of a normal diet. If you find the 16-hour fasting window to be too much at first, start with a 12 hour fast during the time when you would normally be sleeping.

While the first few days may be tough, full of hunger pains, headaches and low-energy, you’ll find very quickly that those initial symptoms go away and you will feel less hungry, more alert and your mind will be clearer. Hunger pains are just your body’s normal response to preparing for a meal – when you break that habit, you’ll find they go away. Think about it – if you are constantly eating (those small meals every 2-3 hours we’ve all heard are good for you) and putting calories into your body, it has no reason to start burning fat. If you need a distraction while you’re getting used to this diet, drink more water, drink green tea and workout during your fast – you may find your workouts to be more beneficial and you’ll have more energy and determination to keep going. Keep busy at work, or at home, with tasks that don’t involve food.

One of the best parts about the IF diet, besides that it is so easy to follow, is that nothing (in moderation) is off limits! You can still have chocolate, ice cream, pizza and wine/beer/liquor. Just be smart about how much you ingest, as you don’t want to derail all the awesome progress your body made during the rest of the day.

Finally, one last note – don’t expect to drop 10 pounds in the first week with an IF diet. Any responsible and effective weight

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

loss or health plan is only successful with consistency and gradual changes. This is the type of thing you will see develop over time, and in the end, you will find it is much easier to stick to lifestyle changes that happen gradually rather than all at once. The more weight you have to lose, the better your results will be.

Good luck, and happy fasting!

Author’s Note: I started a 16:8 diet about two months ago and have already noticed significant changes in my body composition and energy levels. Happy to help with any specific questions or advice!

The Business of Business

How to Draft RRI Responses to Avoid Admissions & Potential Liability Mark Lies II and Adam R. Young

T

he Federal Occupational Safety and Health Administration (OSHA) requires employers to report certain serious injuries by telephone within 24 hours of the employer becoming aware of the incident. These include any employee inpatient hospitalization for treatment, amputation, or loss of an eye. Any fatality, including one caused by a heart attack, must be reported within eight hours. Under OSHA’s guidelines, fatalities, hospitalizations of employees and employers with a history of injuries could result in an on-site inspection as a result of the initial report.

Initially, OSHA has the option to request that the employer conduct a Rapid Response Investigation (RRI), using the RRI form. OSHA reports that it requests an RRI form following most accidents, and generally does not require an on-site inspection of the workplace. But the RRI form responses can form the basis for a subsequent OSHA inspection. Accordingly, employers needs to be careful what they put on this form to avoid an “admission” of OSHA liability which can be civil or criminal.

42 | JUNE.17

Additionally, since the RRI responses are not legally privileged, they are discoverable in civil, third-party litigation.

Thus, management admissions to OSHA in the RRI pose a risk of triggering an onsite inspection and citations.

NOT A SAFE HARBOR

GENERAL RECOMMENDATIONS FOR RESPONSE

While OSHA claims that the RRI creates a “safe harbor” for an employer’s internal investigation, it can use employer admissions on this form to conduct an investigation, and will interview managers and employees to confirm the specific facts or statements made in the response. When confronted with the prior statements, managers may have a difficult time explaining the context of factual misstatements of non-compliance or erroneous factual information in the RRI. Citations can be based on any subsequent management admissions. As reported at a recent American Bar Association OSHA conference, the agency estimates that the majority of citations are based on the employer’s admissions of violations, in documents and spoken to the investigator.

When answering the RRI questions, employers should follow some general recommendations: Be Truthful—First and foremost, your RRI responses must be 100% factually accurate.

Do not make any misstatements. The Federal Department of Justice regularly prosecutes employers and managers who make material misstatements to federal officials as obstruction of justice or a false statement, both of which are a felony.

Keep it Simple and Short—Employers do not need to provide lengthy responses on the RRI form. Include the minimum amount of essential information to clearly describe what occurred and the Company’s corrective actions taken, if any.

Answer the Questions Asked—Limit responses to the questions asked and do not digress into potential hypothetical situations or events.

Avoid Speculation—The Company only should report what witnesses actually saw or what the Company firmly knows from physical evidence and not what someone thinks “may” have occurred. Speculation on the cause of the accident can create unnecessary admissions. In addition, there is no regulation that requires the employer to conduct a root cause analysis in order to complete the RRI form. In the case of a serious accident, if the employer decides to conduct a root cause analysis, it should consider having its legal counsel involved from the outset to direct the investigation and to create legal privileges for the root cause analysis, attorney client and work product, which will protect the investigation from disclosure in OSHA proceedings or other litigation.

When it Doubt, Seek Advice from Experienced Outside OSHA Counsel— If the employer engages experienced counsel, it can avoid preparing an RRI response that can create potential liability.

SPECIFIC RESPONSES ON THE RRI FORM A blank RRI form, also known as an “Attachment A” NON-MANDATORY INVESTIGATIVE TOOL, has been designed to accompany this article and can be downloaded by scanning the code here or by visiting the online version of this story at www.concreteopenings.com.

Please take particular note in answering the following questions: Section C1: Date and time of the incident If you do not have eyewitness testimony, do not speculate as to the time of the accident. You can provide a range of dates if the accident occurred in the late evening, and no one knows for sure when it occurred.

Section C3: What was the employee doing just before the incident occurred?

If you do not have reliable eyewitness testimony, do not speculate as to what the employee was doing at the time the incident occurred. A permissible answer would be “Unknown, no eyewitness

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

testimony.” If you want to state your best assessment based on physical evidence as to what occurred, an example could be “Unknown, no eyewitness testimony. The Company believes that the injured employee was loading widgets into the grinder.

Investigation continues” Section C4: What happened?

A simple description of what occurred is sufficient. No regulation requires the employer to do a root cause analysis on the accident and to provide an exhaustive chronology of facts. Likewise, employers do not have to generate written employee statements or photographs to submit with the RRI. Again, if you do not have reliable eyewitness testimony, do not speculate as to what the employee was doing at the time the incident occurred.

If you do want to provide basic detail, a proposed answer could be: “Coworkers saw the injured employee remove a machine guard and place his hand in the operational grinder machine.”

Section C5: What was the injury or illness?

Again, a simple statement is appropriate. You are not required to provide a detailed medical description of the injury or illness. If an employee injury or illness has been diagnosed by a doctor, provide that summary diagnosis. If the injury is clear (e.g. finger amputation), provide that description.

Otherwise, do not speculate beyond your knowledge, simply state: “The employee injured his finger” or “the employee’s finger was amputated.”

Section C6: What object or substance directly harmed the employee?

Again, if you do not have reliable eyewitness testimony or unquestionable physical evidence, do not guess as to what the employee was doing at the time the incident occurred. Be careful speculating as to what occurred. “The employee was discovered on the floor next to a fallen ladder. It is believed that he was injured and may have fallen. Investigation continues.”

Section D: What caused or allowed this incident to happen?

OSHA’s instructions ask for a full analysis of the equipment, policies and compliance. Keep the answer short and limited to known facts. If the employee was properly trained and did not comply with his training or use an appropriate tool, practice or safety device, which would constitute

employee misconduct and a potential defense to an OSHA violation, describe the misconduct.

Section E: Corrective actions taken to prevent future incidents OSHA is less likely to conduct an inspection if it believes that corrective actions to prevent future accidents have been taken. Taking corrective action is not an admission of liability for OSHA violations, but it should not be described in terms of an action that the employer “should” have taken before the accident and “failed” to do so, which would be an admission.

Employers should specify what actions they have taken following the accident. The most common actions would be retraining employees on proper safety procedures, use of tools or safety devices or wearing of personal protective equipment (PPE).

CONCLUSION It is recommended that employers utilize the RRI to respond, although the employer always has the option of a narrative in letter format. In either event, the response must be factually accurate and not based on speculation, which may not be accurate. In addition, the employer is not required to admit any violations in the RRI, which can occur if the employer does not limit the response to know facts about the event and description of any corrective action. In the event of a serious injury or fatality, engagement of experienced OSHA counsel should be considered to create legal privileges.

Between high-speed air races like the ones at the Reno Championship Air Races in Nevada, STIHL employee and One Moment race plane pilot Andrew Findlay likes to catch up with all the latest news in Concrete Openings magazine!

Makita Releases 5-inch Angle Grinder Makita is pleased to release the GA5042CX1 high power angle grinder with 5-inch tuck point guard with SJS™II technology. The tuck point guard is an efficient solution for clean and accurate tuck pointing and cutting to a depth of 1 inch.

The 5.4-pound grinder can also be used with the standard grinding guard (included) for a range of cutting, grinding and polishing applications.

The GA5042CX1 is equipped with SJS™II, a leaf spring and cam gear drive mechanism that is engineered to reduce vibration for increased operator comfort during extended use. It works by transferring the vibration through the wheel accessory spindle and onto a CAM component. The 12-AMP motor delivers 2,800-11,000 RPM. Additional protection features include a zig-zag epoxy applied to both sides of the armature coil and a powdercoating to the field.

AT THE ANNUAL CONVENTION AND QUARTERLY MEETINGS The number one benefit for members has always been the opportunity to network with cutting professionals at the annual convention and quarterly meetings.

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.

24/7

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.

TESTIMONIAL I have been involved in the GPR imaging side of the industry for 10 years now, working with CSDA Past President and lead training instructor Rick Norland to provide GPR services to contractors, government agencies, engineering firms and private industry. This is where my involvement with the association began.

TRAINING

Simply put, CSDA is an association where a lot of people from different generations of the industry can get together to collaborate on new ideas and reinforce the old ones that have proven successful. This helps our Mark DeSchepper Construction Solutions industry tremendously. I regularly attend Paola, Kansas the quarterly Board & committee meetings mdeschepper@construction-solutions.com because it gives me a unique opportunity to network with individuals related to my part of the industry and gather some invaluable knowledge.

However, it’s not all about what you can acquire from the association and its events. By taking a more proactive role within CSDA—chairing the GPR Imaging Committee and now serving on the Board of Directors—I am able to play a part in shaping and evolving the association as we head into the future. This came to fruition earlier this year, when CSDA held its first GPR Certification course during World of Concrete. I was extremely honored to lead the course and help provide a structured program for experienced GPR technicians. As part of the next generation of industry leaders, I feel participation in CSDA is of great importance.

OVER 4,000 INDUSTRY PROFESSIONALS HAVE GRADUATED FROM MORE THAN 20 CLASSROOM, HANDS-ON AND ONLINE CSDA TRAINING AND CERTIFICATION PROGRAMS FOCUSED ON CUTTING DISCIPLINES, ESTIMATING, POLISHING AND SAFETY. ONLINE TRAINING AT WWW.CSDATRAINING.COM OFFERS A COST-EFFECTIVE ALTERNATIVE TO THOSE NOT ABLE TO AFFORD THE TIME OR THE MONEY TO SEND OPERATORS TO CLASSES.

Director’s Dialogue

Committee Membership

PATRICK O’BRIEN Executive Director

M

uch has changed with CSDA over time, but one constant remains that has played a key part in the continued success of the association. That one constant is the dedication and focus of committee members on behalf of the association.

No one individual or group can achieve the success CSDA has earned, but the combined efforts of many have made a fantastic difference. Perhaps the most visible people to the general membership are the Officers and Board of Directors. These leaders started serving on one or more committees many years before they were elected.

Committee members are a key group and form the backbone of the association by accomplishing many projects that advance the association and the industry. These members meet in small groups and volunteer their time and talent to complete numerous projects that directly benefit CSDA members. CSDA could not offer so much to members if it were not for these dedicated folks.

The committee members have a genuine desire to give back to the industry that provided them with the opportunity to become successful. But they also gain so much more from the relationships that they develop by networking with other members. Many members have made life-long friends through CSDA and have benefited professionally as well.

60 | JUNE.17

Increasingly a newer group of young men and women are becoming involved in the committee work. Many of the leaders who served the association for years are now closer to the end of their careers than the start. Such an evolution is necessary to ensure that CSDA will continue to be a vital factor in the construction community. These younger business leaders can look to the past for knowledge, advice and mentoring and look to the future for inspiration, leadership and innovation.

CSDA Board and committee meetings are held quarterly at locations across North America. These two-day meetings are held in many different cities, allowing local members to attend, learn and network with fellow members. They often continue to work remotely between meetings on committee projects. The committees need to hear member input on what concerns and needs should be addressed to help advance the association and the industry. One of the best ways to provide input is to attend a meeting. Join us and you might like the environment and even decide to join a committee.

All current and potential members wanting to learn more are welcome to attend any Board or committee meeting.

CSDA looks forward to meeting you.
