hank goodness the election is over! It was impossible to watch television or listen to the radio without being bombarded with political ads. No matter your political persuasion, this was a historic midterm election. It was particularly heartening to see young people engaged in the political process.

The holidays are approaching and maybe we will all get an opportunity to slow down a bit, spend some quality time with our families and maybe, just maybe, we will make plans to attend some of the industry events, like the World of Concrete 2019, the Canadian Concrete Expo and of course, the annual Concrete Sawing & Drilling Association Convention.

The World of Concrete 2019 (WOC) will be held again in Las Vegas January 22-25. Last year, the WOC had 58,073 attendees, the largest WOC show in nine years. That is good news for all of us! The economy is strong and construction seems to have recovered. Attendees had the opportunity to view all the latest tools and equipment in our industry.

Technology is changing every aspect of our lives and that is true in our industry as well. WOC gives you the opportunity to meet new people and catch up with old friends. As usual, CSDA is an official co-sponsor of the World of Concrete. We have a booth in the Central Hall (#C4433) manned by friendly CSDA members just waiting to greet you and explain the many benefits of being a CSDA member. CSDA is again offering $25 discounted registration for everyone! Save on WOC registration by using Source Code A26 on the WOC website or go to the CSDA website for a direct link. Using CSDA’s code saves you up to $70 on exhibits-only registration!

But hurry, this code is only good until January 10, when the registration fee jumps up to $95.

As in previous years, CSDA will provide industry specific training classes at WOC. This year, we are again offering our popular two-day Estimating and Concrete Polishing courses, along with two new one-day courses on GPR Methods & Theory and Putting Polished Concrete to the Test, a class on measuring polished concrete. Learn more about these classes and register for the exhibits and CSDA’s training at www.csda. org and click on the WOC banner.

Please also consider attending the Canadian Concrete Expo on February 6–7 held in Mississauga, Ontario. This lovely city is a neighbor to Toronto and sits along the shores of Lake Ontario. This event is the only Canadian national trade show dedicated to the concrete industry.

CSDA’s Annual Convention & Tech Fair will be held March 13–15 at the Vinoy Renaissance Resort & Golf Club in beautiful St. Petersburg, Florida. After the Board and committee meetings, held on March 11–12, we will have presentations, panel discussions and roundtable discussions on valuable new topics like digital marketing, social media, connecting with specifiers and helpful information on the OSHA Silica rule. If you have not been to St. Pete (as the locals call it), downtown is a beautiful, vibrant place to be, right on the waterfront. The Firestone Grand Prix will take place just before our meetings, and CSDA has tickets for sale and an informal venue for gathering if you are interested. The Dali Museum, Beach Drive and Central Ave and of course, the convention itself offer a wonderful opportunity to interact with others in our industry, share wisdom and have some fun together at the social events that are planned. We would like to continue on the success of last year’s convention on Maui, so please consider coming to Florida this year.

I hope to see you all in St. Petersburg!

Go with the Flow Precision Required Means Diamond Core Drilling Is the Way to Go

T

he city of Houston, Texas is growing at a rapid pace, adding about 95,000 new residents each year and is the fifth largest metropolitan area in the U.S. To keep up with this population boom, the city realized a need to double its current water output. A redesign project of the East Houston Water Treatment Facility was needed to update the water treatment plant and piping to increase water flow and meet the growing population demand.

6 | DECEMBER.18

Each core took a day to a day and a half to complete.

In March 2018, CSDA member Aggregate Technologies of Houston was contracted by general contractor CYMI to core drill three very large holes into two of the concrete walls of the water treatment plant to allow for new piping to be installed. The biggest challenge of this job was that the holes were to be drilled 15 feet above the ground, creating a challenge for maneuvering the needed equipment into place and handling the weight of the large cores. Diamond core drilling was determined to be the best method for this job because the holes needed to have clean, smooth edges so that a water-tight seal could be created when the piping and link seals were installed. Additionally, these output pipes would be visible from the road, and other methods such as jackhammering or chiseling would not have created the smooth edges needed for the seal or for a visually appealing finish.

The first step for Aggregate Technologies was to plan the set up of the core drill. The existing piping on the wall needed to be

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

removed, and a meeting with the general contractor was required to plan out the precise drilling plan to ensure the holes were drilled to the correct tolerances. The new piping was temporarily placed so Aggregate could mark the core drill setup on the wall, and then removed so the core drill rig could be mounted.

To mount the rig, a crane was provided to lift the core drill post into place and placed against the wall, so the two anchors could be set. Hilti roto hammers and drop-in anchors were used on this project. Once the anchors and post were set, the drill bit was hoisted by the crane and attached to the rig. To keep the drill bit level, Aggregate fabricated a wheel system that mounted on the drill rig post which eliminated the need to set boards on the wall. This ended up saving several hours of set-up time as well as provided a smoother startup when starting the bit into the wall.

Using a Diamond Products hydraulic core drill and M-6 stand, the two 56-inch diameter holes could now be drilled. The

A special drill rig and anchor set up were required to support the weight of both the drill and the core.

holes took a day to a day and a half each to complete, which ended up being ahead of the planned two days per core schedule. The Aggregate team consisted of one operator and one helper, working in 12-hour shifts. To avoid the core getting stuck in the bit, a small hole was rotohammered in the middle of each core to about one inch of breaking through the end of the 14-inch depth. The bit was then removed, and the core broken out of the wall. This was no small task, as each core weighed 7,400 pounds. Even though the cores were completed ahead of schedule, Houston concrete is very hard, and this wall had been poured in the 1960’s with heavy rebar. The wheel system fabricated

by Aggregate to keep the drill bit level and make for a smoother start helped save valuable time in cutting this hard concrete and allowed the cores to be drilled out ahead of schedule.

Once the two 56-inch holes were completed, another 50-inch diameter core, also 14 inches deep, needed to be drilled using the same technique. In total, three large cores were drilled, as well as several smaller holes in 12 to 18 inch think river rock slab. Three 36-inch diameter holes and three 24-inch diameter holes were drilled in the 14 foot-thick slab, as well as several smaller holes four to eighteen inches thick. To take down the drill rig, the crane was again brought in to lift all equipment down safely.

Aggregate’s main concern on this job was the large diameter holes needed.

These large holes, due to their size and weight, can cause the drill rig to break off the wall if not planned out and secured properly. To prevent that from happening, Aggregate set multiple anchors into the wall at different depths and set them as far away from each other as possible. Since operators were working from a height on a boom lift, all standard PPE was worn, and operators were tied off to prevent falls.

This CSDA contractor completed their portion of this job ahead of schedule and within budget. Aggregate Technologies was chosen for this job due to their relationship and history of successful projects with the general contractor.

With the first 56 inch core completed and broken out, work begins on the second core.

continued

After both 56 inch cores were drilled and broken out, the new pipes were installed.

Project Manager for Aggregate Chris Allen stated “I was very pleased with this job. We expected each hole to take two days due to the large size and the hardness of the concrete. We have drilled smaller holes at the same site that took longer than expected due to the concrete hardness, so it was a testament to our team that this job was completed ahead of schedule.”

Houston aggregate, especially river rock, is notoriously difficult to cut. Selecting diamond tools was the only way to ensure a precise, clean cut and ensure that this job would be a success. Aggregate Technologies’ experience with this type of concrete was one of the main reasons they were chosen for this job, and their knowledge and expertise was crucial in creating the clean cut needed.

Precision and quality, not quantity, were the most important parts of this job and Aggregate Technologies proved they can handle even the most challenging projects.

Cutting for a Higher Power Concrete Cutting Techniques Reinforce Historic Church

The channel created to set the steel T beams is cut.

n August 25, 2016, lightning struck in the wrong place. The 197-foot tall bell tower of St. Mary Church in Columbus, Ohio was struck by lightning during a thunderstorm, causing significant vibration through the wooden trusses supporting the roof and ceiling and disabling the church’s electronics, elevators and pipe organ. The vibration from the strike caused one of the trusses to slip down about four inches and as a result, the brick walls of the 151-year-old church began to lean out under the added pressure from the weight of the ceiling. Due to these structural weaknesses, engineers closed the church on October 7, 2016 until the necessary repairs could be made to make the church safe for worshippers again.

St. Mary Church is located in the historic Columbus area of German Village and was built in 1865 to serve the fastgrowing German Catholic population of the area. It is the tallest structure in German Village, and the third oldest church in Columbus. It was added to the U.S. National Register of Historic Places on December 30, 1974. General contractor Corna Kokosing Construction Company was chosen to lead a $7.5 million restoration project. Part of this restoration would include installing ten steel “T” beams on the inside of the exterior brick walls from floor to ceiling. To install these beams, precision cutting was needed to reduce the risk of damaging the surrounding brick. Corna Kokosing trusted CSDA member Donley Concrete Cutting Company of Pickerington, Ohio to complete this part of the sensitive restoration project.

Operators prepare to guide the steel T beams into place.

Saw cutting was necessary on this job because of the tight tolerances necessary to place the steel beams. Each cut needed to be an exact width and depth so that the beams could be lowered into the cuts through the roof and set back into the cut channel by crane. Any deviations from the set tolerances would have resulted in unplanned and expensive downtime with the crane. Saw cutting the brick walls would also eliminate

continued

unwanted vibration and dust, as excess vibration could have damaged the already weakened structure and the crew needed to follow guidelines to abide by the new OSHA silica regulations.

The first step to create the steel beam channels was to layout the necessary anchor points for the wall saws on all ten cuts. Donley was concerned that the weight of the saw and blade would be difficult to anchor to the walls without damaging the brick, so custom equipment was manufactured to lighten the load. First, a longer threaded rod with additional sleeves and Hilti HY70 epoxy was used to increase anchor strength. Next, a custom 36-inch Diamond Products wall saw blade with a ½-inch wide core and ¾-inch wide segments was manufactured to reduce the weight of the blade. A flush cut bolt pattern was also used to allow additional fasteners for blade security. The blade was attached to a Pentruder 8-20 high frequency wall saw with a custom aluminum blade guard and water hoses designed by Donley.

After the layout of the anchor points was complete, each anchor was hammer drilled and set using the Hilti HY70 epoxy and the additional sleeves. The anchors were left to set for 24 hours. Typically, the anchor holes would be drilled through the brick walls using threaded rods and plates to attach to the sawing equipment, but due to the wall and buttress thickness

of up to 63 inches and the potential for spalling on the exterior, that process was not an option. Instead, Donley used pre-cut threaded rod which was epoxied into the brick using sleeves to help secure it in case of any voids in the brick.

Once the anchors were set, the team began setting up the Pentruder wall saw with the custom Diamond Products blade to create the ten channels. Each channel would require a 40 foot vertical cut ¾ inch wide and 14 inches deep. These cuts were made from the floor to the ceiling, creating the channel for the steel “T” beams to be lowered and set. This process was repeated until the ten channels were cut and ready for the beams.

Once the crane lowered the steel beam into the channel, the beam was grouted in place and the core drilling was able

to begin. Pre-drilled holes in the beams allowed for one-inch diameter cores to be drilled through the 44 to 63 inch thick brick wall and buttress to permanently secure the beam to the wall.

The walls were 24 inches thick, but the beams were added in line with the buttresses, which were thicker at the base of the wall, and tapered towards the roof. Donley used a Hilti DD350 core drill with one-inch Diamond Products core bits to complete the core drilling, which consisted of 40 total cores. When the cores were completed, the final hardware was installed to secure the beams to the brick walls.

This job required extensive attention to detail and extra precautions, as Donley had to make sure their work did not damage any of the existing structure of this historic building.

Cutting with diamond tools was the chosen method of creating the channels for the beams, as chipping, chiseling or jackhammering could not have created the deep narrow channel required, nor could it have been performed without disturbing the adjoining bricks. Any falling debris could have damaged the existing wood floors or the intricate plaster carvings along the walls, which were to remain in place. Donley also had to make sure they fully contained the slurry created during the sawing and drilling process. Shoring towers had previously been erected to help carry the weight of each roof truss while the renovation

St. Mary Church in German Village St. Mary Church was constructed in 1865 to serve the fast-growing German Catholic population of Columbus, Ohio. The 197-foot tall spire was added in 1893. By 1965, Columbus’ population was one-third German.

More than 1,600 buildings have been restored since 1960.

occurred, and these towers happened to be directly in front of each location to be cut. Lifts and/or scaffolding could not be used in the congested area, so the shoring contractor installed platforms attached to the shoring towers every seven to ten feet to allow the crew to perform the 40 foot vertical cuts as well as the core drilling. Donley was able to also use this framework to install plastic sheets from floor to ceiling to contain the slurry. After each cut was performed, the slurry was vacuumed from the containment area using Hilti VC 40 U vacuums and properly disposed.

Operators wore all standard items of PPE and were secured with harnesses to retractable lanyards while working on the shoring towers. These lanyards were secured to the attic above each work area.

In the end, Donley Concrete Cutting performed 400 linear feet of saw cutting for the ž-inch wide and 14-inch deep vertical cuts in the brick walls. They also core drilled 40 holes one-inch in diameter and 44 to 63 inches deep.

The job was completed on time and within budget, with the cutting and drilling portion taking about six weeks. All ten of the beam channels were cut to within the required

tolerances. Donley Project Manager Jason Young stated “I was very pleased with this project from start to finish. There were some unknowns that we had to work through as a team, but everyone gave one hundred percent and the end result was perfect!”

Jim Valentas, Senior Project Manager for Corna Kokosing spoke highly of the Donley Concrete Cutting team after the job was completed. “Corna Kokosing has worked with Donley Concrete Cutting for many years. They are a trusted partner on our projects and this project was no exception. As we reviewed the various potential structural fixes, we ultimately landed on the Structural T columns, but only after meeting with Donley at the church to confirm means and methods of doing the cuts. We relied on their expertise and recommendations to finish up the drawings and ultimately put the plan into place. Based upon years of working together, we knew that their safety culture aligns with ours and that the methods they came up with to do these vertical cuts would be done safely. They worked through the plan with us ahead of time and then executed that plan perfectly, allowing us to maintain the overall schedule and work towards reopening this church for Easter 2019. We are grateful to have a trusted partner in the concrete cutting field whom we can rely on for our day to day needs as well as those unique opportunities that come our way,” said Valentas.

The precision of diamond tools and expertise of this CSDA contractor shows that CSDA cutting contractors can successfully tackle sensitive jobs with professionalism and confidence and ensured that St. Mary Church will be standing for years to come.

90-Year-Old Link Between New York and New Jersey Broken Goethals Bridge Demolition

T

he Goethals Bridge opened 90 years ago on June 29, 1928 to accommodate increased interstate automobile traffic following World War I. It is one of three critical Staten Island bridges linking New York and New Jersey. It was named in memory of Major General George Goethals who was the construction manager of the Panama Canal and the first consulting engineer for the Port Authority of NY & NJ.

After its long history of service connecting Elizabeth, NJ with Staten Island, NY, the Goethals Bridge had now become functionally obsolete. The original bridge had 10-foot-wide narrow lanes that are substandard to the current use of 12-foot-wide lanes. The 1928 bridge design also lacked roadway shoulders, provided no access for pedestrians or bicyclists and seismic protections were not part of the design.

The Port Authority decided that a replacement bridge was needed to avoid the hundreds of millions of dollars that would have been required to maintain the old cantilever bridge span. In 2013, the Port Authority authorized the $1.5 billion project to build a pair of cable-stayed bridge spans to replace the single cantilever bridge.

Building of the first span began in 2014. The demolition of the original bridge began in 2017 once traffic was switched to the first of two cable-stayed bridges to the south. The second span of the new bridge was built right next to the old Goethals Bridge, and demolition was required to complete this phase of the next bridge span.

The general contractor for the bridge demolition work was R.E. Pierson Construction. They required a contractor to provide a substantial amount of saw

cutting to facilitate the demolition of the old bridge deck, sidewalk and parapet wall structures. “We used J. P. Hogan Coring & Sawing for our road saw cutting, coring and wire sawing associated with the demolition of the Goethals Bridge between Elizabeth, NJ and Staten Island, NY� according to Frederick L. Stuart III, P.E., Construction Manager, R.E. Pierson Construction of Pilesgrove, NJ. Sawing and drilling with diamond tools offered many benefits for this project, including maintenance of structural integrity, reduced downtime and the ability to cut heavily-reinforced concrete. These factors played a major role in the demolition of the existing Goethals Bridge with its arch pier superstructure. A critical factor was to not damage the new bridge or the surrounding structures, and using diamond cutting would help achieve that.

J.P. Hogan cut many of the larger concrete sections into pieces for removal by R.E. Pierson with their crane. Others sections were simply core drilled and wire sawed so they were able to be pulled over out of the way by R.E. Pierson.

The piers had to be safely dropped to the ground, and the only way to effectively do that was through the use of diamond wire sawing of the vertical structural rebar. J.P. Hogan drilled two-inch diameter wire pull holes with a Shibuya Core Drill R2531 through up to 23-foot thick reinforced concrete at heights of up to 130 feet.

Five inch diameter lifting holes were also drilled through up to 23 feet of reinforced concrete at those heights.

In the end, up to 330 square feet of horizontal pulls on each pier were made by the cutting contractor.

The selection of the right diamond tools is always critical and the expertise of a seasoned CSDA cutting contractor often makes a tremendous difference in the performance and success of the job. Such was the case with the large steel reinforced piers and the challenge to select the optimum diamond wire to Cables attached to the top of the pier to pull it down.

efficiently work with this large amount of steel. A Hilti DSW 3018-E high power (30 kW) electric wire saw was utilized to pull from the ground all the way to a height of 130 feet. This required spinning a length of 300 feet of diamond wire. The initial diamond wire selection proved to be less than ideal, and adjustments were made identifying a different wire specification that was able to boost production by 30 to 50 percent.

Other environmental concerns presented challenges to satisfy the requirements set forth under the U.S. Department of Transportation Federal Highway Administration’s National Environmental Policy Act (NEPA). This impacted the demolition of Pier C which was in the water, as J.P. Hogan was not allowed to drop any cut pieces of concrete into the water. Operating the wire saw over water therefore required a platform built in the water, allowing operators access to the pier with their track wire saw. This was a challenging feat, but the J.P. Hogan professionals met the challenge to get the job done.

Training and certification of the operators was a requirement for this project. All of the J.P. Hogan operators

had to have high-reach certification to use the JLG ultra boom lift for this demolition. They also needed fall protection and prevention training as required for this project.

J.P. Hogan completed the demolition of approximately a dozen arch piers in both NY and NJ that required 20,000 square foot of wire sawing. They supplied sufficient amount of trained professionals seven days per week on three shifts per day. Two wire saw crews worked the first and second shifts while two core drill crews were on the third shift. This level of support allowed them to successfully complete the work on schedule and on budget.

“The demolition of the 7,500 foot long bridge took approximately 18 months to complete and J.P. Hogan with their state of the art equipment and a team of highly trained employees were able to solve even the most complex sawing and coring challenges. It was a pleasure working with J.P. Hogan and we look forward to future opportunities to work with them!” stated Frederick L. Stuart III, P.E. Once again, a CSDA cutting contractor has demonstrated the benefits of utilizing sawing and drilling diamond tools in the hands of professional operators to offer the construction industry the ability to lower total project costs, while providing the capability to work in limited access areas to remove challenging concrete structures.

Respirable Crystalline Silica for Construction, One Year Later

By Gary Sauer

O

n September 23, 2017, the enforcement of the Federal Occupational Safety and Health Administration (OSHA) standard for the occupational exposure to respirable crystalline silica in the construction industry commenced, and through September 2018 there have been 141 inspections resulting in 389 citations. This is only data from federal OSHA enforcement, not individual state plans, (i.e. California, Michigan) that are currently being more active with enforcement. This makes it apparent that this standard is and will be enforced by OSHA throughout all sectors of the construction industry.

Most of the cases were classified as serious violations and even though a serious violation can be as high as $12,935, most penalties averaged $9,500, which is still nothing to take lightly. The largest pending

24 | DECEMBER.18

case to date is a large employer in Virginia with a proposed fine for willful violations of $304,130. Virginia operates a state-run OSHA plan.

The most frequently cited violation is incorrectly or not monitoring the jobsite exposure levels, which leads to not correctly following OSHA’s Table 1 procedures.

Employers need to be knowledgeable about the new standard and train their employees properly. There are common activities and environmental variables that one would not think of that could raise the levels of silica exposure such as dry sweeping, working near gravel/dirt roads and/or parking areas, and even direction and wind speed can all play factor into the action levels. Another concern with the silica standard is it overlaps into other standards such as Respiratory Protection, Hazard Communication, Housekeeping

and the General Duty Clause, which is all encompassing. Every construction crew needs to have a trained competent person onsite that can evaluate the task and the jobsite and implement a worker exposure control plan and help interpret and instruct Table 1 properly.

A good resource is the OSHA website and search “silica” in Construction FAQ. Most likely, you will find that someone has already asked the question you are concerned with and OSHA has supplied the answer. Examples of questions that could be asked are listed below.

WHAT IS OSHA’S SILICA TABLE 1?

Table 1 is a list of silica-generating tasks along with specific engineering controls and respirator requirements. Table 1 matches common construction tasks with dust control methods that can be used to limit worker exposures to silica, so employers know

exactly what they need to do for that job and workers. The dust control measures listed in Table 1 include methods that are known to be effective, like using water to keep dust from getting into the air or using ventilation to capture dust. In some operations, respirators may also be needed. If an employer chooses to use a method in Table 1, they will be assumed to be below the permissible exposure limit and may not need to measure workers’ exposure to silica.

HOW CAN AN EMPLOYER DETERMINE WHO QUALIFIES AS A “COMPETENT PERSON” UNDER THE STANDARD? DOES AN EMPLOYEE HAVE TO TAKE A PARTICULAR TRAINING CLASS TO MEET THE DEFINITION OF A COMPETENT PERSON UNDER THE STANDARD? The standard does not specify particular training requirements for competent persons.

Instead, it defines a competent person in terms of capability, i.e., whether a designated competent person has the knowledge and ability to perform the duties prescribed by the standard. The employer must also give the competent person the authority to perform those duties. See 29 C.F.R. § 1926.1153(b).

To determine whether a given employee has the appropriate knowledge and ability to perform the duties of the competent person, an employer needs to confirm that the employee is capable of: (1) Identifying existing and foreseeable silica hazards; and (2) Promptly eliminating or minimizing those hazards.

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

In addition, the employee must be capable of making frequent and regular inspections of job sites, materials and equipment for purposes of implementing the written exposure control plan. They must also ensure that the engineering controls, work practice controls, required respiratory protection, housekeeping measures and procedures to restrict access in the workplace are implemented for the silicagenerating tasks listed in the plan. A person with these capabilities (whether acquired through training, education, work experience or otherwise), who is authorized by the employer to perform the duties of a competent person, qualifies as a competent person under the standard.

IF ALL THE JOBS AND TASKS AN EMPLOYER PERFORMS ARE INCLUDED ON TABLE 1, CAN THE EMPLOYER COMPLY WITH TABLE 1 EXCLUSIVELY, INSTEAD OF FOLLOWING ALTERNATIVE EXPOSURE CONTROL METHODS? Yes. Most of the tasks that generate exposure to silica in construction are listed on Table 1, and OSHA anticipates that most employers will choose to follow Table 1 for tasks listed on the table.

One of the best ways to become more knowledgeable and receive information, support and training is through trade associations such as the Concrete Sawing & Drilling Association (CSDA), American Society of Concrete Contractors (ASCC) and Construction Employers Association (CEA). These associations can offer assistance on a written

exposure control plan, properly interpreting and using Table 1, recommendations of independent safety and hygiene companies to assist in completing a proper exposure assessment and perform scheduled air monitoring testing.

Many associations, including CSDA, have or are developing a database of silica data and can supply performance and objective testing results. Many of them are now sharing this information with each other to expand their data and increase the access to this data. It is a benefit for contractors to have access to as much testing data as possible.

Most associations also offer training in construction safety, including Silica Competent Person (CSDA is now offering Competent Person training). This may be a better fit for some of the smaller companies where training can be completed in the winter months when business is slower. Larger companies may consider looking into independent safety and hygiene companies, such as Safety Controls Technologies, Lancaster Safety and ESC Safety Consultant, and there are many local consultants. These companies can come to your facility and do in-house training, safety audits of current programs and a full evaluation of your safety program. Most of these companies will customize their training to fit your individual needs and situations for a fee.

Government organizations also offer resources, some for free. OSHA offers an abundance of literature, videos and E-tools.

There other government organizations such as National Institute for Occupational Safety

& Health (NIOSH) and American Congress of Governmental Industrial Hygienists (ACGIH) that have plenty of publications to obtain information.

There have been some organizations formed that are non-profit companies such as CPWR — The Center for Construction Research and Training, which has a series of cooperative agreements with NIOSH and part of the Center of Disease Control (CDC).

This organization has a significant amount of training resources, toolbox talks and templates on how to write safety programs such as silica action plans, Haz/Com plan, lock-out, tag-out and more. They are currently collecting data on silica, noise levels and lead to build a data base. In Ohio, they have the Bureau of Workers Compensation (BWC), a state-run workers insurance system. Through the company’s premiums, they have safety consultants that will come onsite and provide safety training, publications, programs and even industrial hygiene monitoring at no additional cost.

Check to see what your state offers.

Manufacturers are another resource for information and assistance in lowering silica

CSDA Silica Resources CSDA offers many resources relating to the OSHA silica rule, including a section in the CSDA Safety Manual, information listed on the CSDA website and will offer a roundtable at the 2019 Convention & Tech Fair for contractors to discuss the various methods they are using to adhere to OSHA’s standards. For more information, please contact the CSDA office at 727-577-5004 or info@csda.org.

levels through practices and new equipment.

All the manufacturers supply water systems or at least recommend using water when applicable. Most are coming out with dust collection systems on a lot of their equipment, especially with the smaller and hand-held products. Some of the larger manufacturers are collecting objective data on their equipment and they are sharing this data with their customers. Some even have it on their websites for anyone to review.

One year in and we can see that enforcement for the silica standard is happening, and the penalties will only get larger. But unlike other standards in the past, it

7,313x4,625_floor saw_MC570.pdf 1 13.07.2018 10:10:10

seems like this standard is bringing out a larger more cooperative action between government agencies, trade associations and nonprofit organizations. With the sharing of information and data we will get more educated on the hazards of silica and learn to lower and control silica on the jobsite.

More information is being collected and shared every day and we all need to make that effort to get ourselves and our employees and operators educated and trained for a safer work environment for all.

IACDS President’s Insight

M

illennials - sat in front of their phones, tablets or on-demand TV, more worried about the latest reality TV star’s next Instagram post than they are about embarking on a career or, to start with, just finding themselves a job of any kind.

A fair assessment, you might say – but is our stereotyping of a whole generation one of the reasons that all of us are struggling to find the future workforce that will ensure our businesses and industries continue to run for many more years to come?

I was inspired to write this column when I saw a presentation

by David Perkins of Hilti at the CSDA 2018 Convention in Maui and then, again, at the IACDS Tokyo Conference by Erin O’Brien of CSDA. It really got me thinking and got me doing a bit of research when I returned back to the UK. What is a Millennial? In the UK, it’s basically anyone who was born between 1980 and 2000. In 2016, there were 16.8 million – a quarter of the whole population, and the largest proportion of the workforce compared to other generations. We can be confident that these figures are reflected, if not completely mirrored, around the world. The U.S. uses a slightly different measure – anyone born between 1982 and 2004 – and they make up around 75 million of the population but, still, the stereotype remains the same.

Perhaps, we as an industry, should be the first to look beyond the Millennial label. After all, construction and all of its specialties is probably one of the most typecast industries on the planet. The sector we work in requires intelligence and skill and yet we are labelled with the opposite stereotype. How, then, can we be willing to label a whole generation in one way?

We can’t, and actually, research shows that this generation is not the selfish, self-absorbed group that the stereotype suggests.

Surveys have found that Millennials are looking for substance and meaning in their work and not just the biggest pay check. They care about a company’s brand and reputation and want to feel what they are doing is contributing to something worthwhile. They are willing to work – with a large proportion working in excess of 40 hours a week and many undertaking two jobs in order to generate the income they need.

Of course, technology plays a big part in their life, as 91 percent are regular internet users – but is that something employers should fear or is it something we need to embrace?

JULIE WHITE IACDS President

“But they just quit when the going gets tough,” I hear you say. Maybe some do, but the biggest reason given for leaving a job is there are no opportunities to advance, little growth in pay, excessive hours, lack of teamwork and a lack of flexibility. So, we have a stereotype of a generation and a stereotype of an industry but neither match what’s happening in reality.

Therefore, if we are to find new blood for our businesses, there is no question that we are going to have to dip into the pool of talent from the Millennial generation and look beyond the stereotyping.

In order to do so, we have to sell our industry better and, maybe, look at some of those factors that are important to those surveyed – such as flexibility and the opportunity to progress. Also, we have to be willing to bestow the importance of construction on society and the economy. Without us, there are no roads, no schools, no homes, no hospitals – I could go on. If a young worker is looking for meaning in what they do, what could offer that in greater abundance than being part of an industry that is creating the future for generations that are yet to be named and yet to be stereotyped?

So, tell me, what are your experiences of Millennials and has this made you think about your recruitment policy for the future. It’s a subject that is going to come up again and again and will definitely be revisited by the IACDS at future conventions.

A Case for Red Meat

By Erin O’Brien

F

all means hunting season is here in much of the country, and I know there are a lot of concrete cutters who enjoy it. What many of you may not realize is how good that venison, feral pig, elk or wild-caught salmon is for you. Up until about 50 years ago, most of the meat humans consumed was hunted or caught. Factory farms and large-scale livestock operations are a recent development and have contributed greatly to the vilification of eating meat, especially red meat.

For thousands of years, humans didn’t have a grocery store or Amazon Prime to rely on for their food. All food was hunted or gathered, and the animals that were hunted existed in a free-range, organic and all-natural environment where they feasted on wild grass, grains, vegetables and other smaller animals.

This meant these animals, when hunted and eaten by humans, passed along those healthy nutrients from their wild diets to the people who consumed the meat. There were no added hormones, steroids, chemicals or confined and dirty living spaces. But as we embarked on the Industrial Age, technology advanced and the world’s population skyrocketed, allowing and demanding the development of industrial farming and livestock operations. Now, cows, pigs, chickens were raised in close quarters which bred diseases that required medication and antibiotics. No longer were these animals free to roam and eat their native diets. They were fed processed grains or whatever was cheap, and chemicals were added to make them grow faster and fatter so that these farms could maximize their output of beef,

30 | DECEMBER.18

pork and chicken. The wild grasses, grains and vegetables full of nutrients were no longer part of their diets to create lean muscle, and instead of those nutrients being passed on to the people who consumed the meat, instead we got hormones, antibiotics, chemicals and meat full of fat.

So, society decided that this meat (red meat, especially) was terrible for us. Full of chemicals and coming from unhealthy animals who were mistreated and abused, red meat was now taboo in many cases and people were discouraged from consuming too much of it.

So far, sounds like I am also telling you not to eat red meat, right? Well not quite. The point is that red meat, when coming from animals who could roam free and eat a healthy diet, is actually good for you. It’s just not as common as it should be.

Let’s go back to why red meat is so good for you. First, beef is not the only red meat.

Pork, when coming from a natural source, is supposed to be red. Other red meat options are buffalo, elk, feral pig, deer, caribou and ostrich.

Organic and free-range or pastured red meat is high in protein, micronutrients, amino acids and two to three times more omega 3 fatty acids than red meat you’ll find in most supermarkets.

Omega 3 fatty acids are very good for you and necessary to help your body function properly.

When you look at what wild and pasture-raised animals eat, you’ll see things like grasses, alfalfa, clover, hay, berries and more. All these things contain nutrients that our bodies need as well, so it makes sense to consume animals that were raised on this type of diet, rather than one who was fed a diet solely of processed grains.

Unfortunately, this kind of quality doesn’t come cheap, so organic, free-range and pasture-raised meat will be more expensive and harder to find than the mass-produced options. However, this is a small price to pay when it comes to your own health and well-

being. It is becoming increasingly easier to find good-quality red meat now, with options at health food stores, farmer’s markets, local farms and even online. There are some options highlighted at the end of this article if you are interested. Of course, the best way to ensure that your red meat is of the highest quality is to hunt it yourself – most hunters will tell you the best meat they’ve ever had is what they have provided themselves.

Once you have your quality red meat, you’ll want to take the same care in cooking it. Aging red meat in cool temperatures is a natural way to bring out more flavor and tenderness.

Red meat should also not be overcooked, as it will make the meat tougher and many of the micronutrients are lost during high-heat cooking or when the meat is cooked for too long. (People who order their steaks well done – I’m looking at you! STOP!) It’s not realistic to expect to eat highquality, organic, pasture-raised, free-range red meat always. But if you can be more mindful about the source of your proteins, you will not only feel better because your body is getting much-needed nutrients and not getting hormones and chemicals, but you can also feel good because you are supporting natural and sustainable farming or hunting practices. Do the best you can, when you can and encourage others to do the same. Visit your local farms, farmer’s markets and vendors who produce healthy and sustainable products.

Safety Counts

How to Reduce the Risk of an OSHA Repeat Citation

By Mark A. Lies II & Daniel R. Birnbaum

T

he Occupational Safety and Health Act of 1970 (Act) is enforced by the Occupational Safety and Health Administration (OSHA), who has the duty to inspect workplaces and to issue citations if it determines that an employer is in violation of the Act. Most employers who are cited are frequently tempted to settle a citation quickly at the informal conference for a reduced penalty, rather than contest the citation.

Foregoing potential factual and legal defenses for a quick and easy resolution of a citation can create a much larger risk in the future: a “repeat” citation with substantial monetary penalties.

A repeat citation can carry a penalty of up to $129,336 per citation item and will continue to increase annually in line with the consumer price index. Traditionally, a repeat citation would be issued when OSHA had previously cited the employer for a “substantially similar condition” and the Occupational Safety and Health Review Commission (OSHRC) had affirmed the previous citation. Recently, a significant ruling from OSHRC increased OSHA’s evidentiary burden to prove a repeat violation. This article will discuss what constitutes a repeat citation, OSHRC’s recent decision involving a repeat citation that was favorable to employers and practical advice and best practices for minimizing the risk of a repeat citation.

WHAT IS A REPEAT CITATION? A repeat citation is a type of violation for which OSHA may cite an employer under section 17(a) of the Act if, as the name implies, OSHA has previously cited the employer for a “substantially similar condition” and the OSHRC has affirmed the previous citation. Many employers are unaware of the nature of the various types of citations (General Duty Clause violation and/or violation of specific regulation) that can be considered “substantially similar” to be the basis for repeat citations. For example, OSHA can issue a repeat citation under the General Duty Clause or base a repeat citation on a previous violation of the General Duty Clause. In its Field Operations Manual (FOM), OSHA states that “Hazards presenting serious physical harm or death

34 | DECEMBER.18

may be cited under the general duty clause (including repeated violations that would otherwise qualify as serious violations).” In addition, OSHA can base a repeat citation of a specific regulation upon a prior citation under the General Duty Clause.

For those employers with more than one facility or worksite, an alleged repeat violation can occur at any of the employer’s facilities or worksites nationwide in federal jurisdictions, regardless of where the initial citation occurred. Federal OSHA must use federal OSHA citations as the basis for a repeat citation. The FOM states that, “Prior citations by State Plan States cannot be used as a basis for Federal OSHA repeated violations. Only violations that have become final orders of the Review Commission may be considered.” OSHA maintains a national online database (which is available to the public on their website). OSHA Compliance Officers can (and do) search for citations previously issued to an employer anywhere in the nation.

While there is not any statutory time limit concerning the length of time between the date on which the repeat citation is issued and the date of the previous citation on which the repeat classification is based, set out in the Act, OSHA’s policy states that the following policy shall generally be followed: A citation will be issued as a repeated violation if: a. The citation is issued within five years of the final order date of the previous citation or within five years of the final abatement date, whichever is later; and b. If the previous citation was contested, within five years of the Review Commission’s final order or the Court of Appeals final mandate.

As indicated, repeat violations can carry proposed penalties of up to $129,336.

Thus, to an uninformed employer, it may appear that a harmless citation, with a nominal proposed monetary penalty, may be settled as a seemingly inconsequential matter. However, such action may lay

the foundation for a subsequent repeat citation and a $129,336 penalty at any of an employer’s facilities or worksites across the nation for years to come. For this reason, informed employers who realize this potential exposure are now aggressively defending any citation that is not factually or legally valid.

WHAT OSHA TRADITIONALLY MUST SHOW TO ESTABLISH A REPEAT VIOLATION OSHA has the initial burden of proof to demonstrate that the subsequent citation is “substantially similar” to the previous citation.

The principle factor to be considered when determining whether a violation is repeated is whether the prior and instant violations resulted in “substantially similar hazards.”

Therefore, OSHA can attempt to meet its initial burden merely by demonstrating that the previous and current citations allege violations of the same standard.

Unfortunately, the potential employer liability can be expanded because the two citations do not have to fall under the same specific standard – OSHA can meet its burden even if the two citations allege violations of different specific standards. This issue is clearly illustrated in the case of Potlatch Corporation, which sets forth the standard in determining whether OSHA has properly classified a citation as repeat, including the following example of two citations of separate standards that would nonetheless qualify as a repeat violation: If two employees performing construction work such as painting were exposed to a 20-foot fall from an unguarded scaffold, the employer would be in violation of 29 C.F.R. § 1926.451(a)(4); a subsequent citation based on exposure of the same employees to a 20-foot fall while using the same unguarded scaffold to replace light bulbs would be a violation of 29 C.F.R. § 1910.28(a)(3).

In addition, the employees and the scaffold described in the Potlatch example above do not have to be the same. Rather, the two citations can involve completely separate employees at completely separate facilities across the country. Thus, anytime

an employer voluntarily accepts a citation, including an informal settlement, OSHA may use the citation as the basis for a repeat citation involving not only the same standard, but also any substantially similar hazard in any of the employer’s facilities anywhere in the nation.

HOW TO PROTECT YOUR EMPLOYEES AND YOUR BUSINESS FROM REPEAT CITATIONS In light of the recent Angelica decision, it will be much more difficult for OSHA to prove repeat citations. Traditionally, if the employer settles a citation or it becomes the final order of the Commission following litigation, it is critical to alert the employer’s management at each of its facilities or worksites across the country of each citation and the underlying hazard. Employers should take timely measures to abate the cited hazard at the cited worksite and to prevent future employee exposure to the hazard at every worksite. In addition, if the employer eventually agrees to accept a citation, the employer should attempt to have the Alleged Violation Description (AVD), which is the factual description of how the violation occurred contained in the body of the citation itself, carefully revised to limit and accurately describe the hazard to reflect the specific facts and circumstances of the hazard. This makes it much more difficult for OSHA to prove that the hazard alleged in any future citation is “substantially similar” to the hazard alleged in the prior citation.

In light of the Angelica decision, following the acceptance of a citation, employers must also take steps to establish that it acted in good faith and took effective and documented action to correct the initial violation. As there is no mechanical way to avoid a repeat citation, and the corrective actions taken will depend on the factual circumstances surrounding the citation, employers should consult experienced counsel for guidance on what constitutes abatement of the citation and how to properly document such actions.

If the employer is unfortunate enough to receive a repeat citation, it should develop a defense strategy to contest the classification of the citation as repeat; that is, that the new citation is not “substantially similar” to the prior citation. While the employer cannot defend the prior citations themselves, it must be prepared to put forward documentary and testimonial evidence to establish that the previously cited hazardous condition did

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

not create a substantially similar hazard as alleged in the subsequent repeat citation.

If these steps are taken, the employer will be prepared to argue that the prior citation was not “substantially similar” to the present citation, as well as any other legal or factual defenses that may exist to refute the subsequent citation.

CONCLUSION When an employer receives a citation from Federal OSHA or a state agency, it must carefully consider the potential for a repeat citation prior to settling the citation for

any reason. If the employer accepts a citation without undertaking the foregoing analysis, the potential liability for a repeat citation will clearly exist in the future.

CSDA Contractor Rescues the Montgomery Locks and Dam Third Successful Waterway Project with the Corps of Engineers

M

ontgomery Locks and Dam is located on the Ohio River five miles downriver from Beaver, Pennsylvania and three miles upriver from the first large-scale nuclear power plant in the U.S. at Shippingport, Pennsylvania. Construction

began in 1932 and the dam opened in June 1936 to permit increased control over the water level in the navigation pool upriver of the dam.

Montgomery replaced the old-style wooden wicket dams built by the Pittsburgh District of the U.S. Army Corps of Engineers to raise the first shallow navigational pool on this stretch of the Ohio River.

Montgomery is busy, with 300 commercial lockages each month and 150 lockages of pleasure craft during the busy summer months. It is located downstream from a large industrial base and requires periodic maintenance to keep the locks and dam fully operational. The most recent project was to provide a new maintenance bulkhead recess. Commercial waterway traffic takes priority and limits the amount of lock chamber time allowed for any upgrades.

CSDA member Matcon Diamond, Inc. of Pittsburgh had successfully completed two prior projects with the local branch of the Corps of Engineers along the waterway around Pittsburgh. They were a natural choice for the new

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

maintenance bulkhead project. All of the work was completely dependent on access to the faces of the chamber walls and per regulations, no work could take place within the chamber during times of active boat traffic.

In order to meet this challenge, planning was the key for Matcon. All materials and equipment needed, along with backups, were staged and ready to be implemented at a moment’s notice so productivity could be maximized during the allowable chamber closures.

The overall project scope consisted of wire sawing and core drilling concrete to accommodate embedded items for the new maintenance closure system in the upstream and downstream

approaches to the 110-foot by 600-foot primary land lock chamber. The wire sawing was conducted from the top of the land and middle wall monoliths to the underwater poiree dam and boule dam sills at the elevations indicated. The bulkhead recess dimensions were approximately nine feet long by four feet deep by 44 feet tall at the downstream locations and nine feet long by four feet deep by 27 feet tall at the upstream locations.

Core drilling, wire sawing, line drilling and other precision cutting methods were utilized for the concrete cutting. Steel corner protection and wall armor were also to be cut at locations for the proposed concrete wire saw.

Matcon was to cut the concrete free and install a temporary Corps-supplied stability system. The Corps removed the concrete sections at a later date.

Due to the age and nature of the structure, the lock and dam could not sustain any percussive demolition activities whatsoever. Diamond cutting was the only permissible method approved by the Corps. Surveyors mobilized to establish precise locations of the future recesses. The next step was to drill vertical nine inch diameter holes at the back corners of the recesses, from the top of the lock walls down to the sill elevations. These holes were to provide access for plunge pulleys for wire sawing operations utilizing the Husqvarna 2512 hydraulic magazine wire saw and Diamond Products diamond wire. Simultaneously, four inch diameter vertical holes were cored with a Longyear hydraulic core drill and K2 Diamond core bits down to the sill elevation for a future stabilization system.

On the faces of the lock walls, Matcon drilled a series of 12 inch diameter holes and 1.5 inch diameter holes horizontally to the depth of the recess (approximately four feet). The 12 inch holes were mandated by the contract for future removal of the blocks by the Corps, and were located along each horizontal cut line, spaced to accept the Corps’ lifting apparatus. The 1.5 inch diameter holes were located at the intersection of each horizontal cut line and the vertical cut lines to provide access for future diamond wire sawing operation. Once all of these holes were completed, the wire sawing operations began. The first sawed cut was the bottom horizontal cut.

Once it was established, the back vertical section was then cut. Then each subsequent horizontal cut was done, working from the sills to the uppermost cut line above the surface. The final cuts were the two vertical side cuts.

These were completed only after a stabilization system was placed, ensuring the blocks would not be able to shift until their removal.

Additionally, due to its age, isolated areas of the walls exhibited pockets of deteriorated concrete. This presented some difficulty during the vertical drilling operations, as the cores would free up and jam in the bits. Only through the operator’s great experience were they able to work through

the challenge of this hang up. The deteriorated areas were also pointed out to and logged by the Corps, and will be addressed in a future project.

Underwater cutting was another challenge, and Matcon subcontracted with a certified diving company for all underwater work. As the prime contractor, Matcon also retained a certified surveying subcontractor and a professional photographer as required by the Corps job specification.

This 3,360 square feet wire sawing project was completed ahead of schedule and well within budget. The Corps was very pleased with the work. This is the third project of this sort that Matcon has completed with the local branch of the Corps of Engineers on the waterway around Pittsburgh. At this time, no future work of this sort is planned on the locks and dam system in this area. “We were very satisfied with the work. This was the third project of this type we had completed for the Corps in the past few years. It was a great opportunity to have our most seasoned drilling and sawing employees to show their talents and train the next generation of cutters.� proudly stated Matcon manager Dan Matesic.

Diamond Tools—An Engineers Best Friend

By George Seegebrecht, P.E.

C

oncrete sawing and drilling makes such a tremendous contribution to our projects but over time, we begin take it for granted. Many of us may not be aware of the benefits and time-saving techniques available for concrete renovation with the use of diamond tools.

Concrete Sawing & Drilling Association (CSDA) contractors can tackle many jobs that help make our projects easier.

For instance, flat sawing or core drilling are used to create penetrations through walls allowing utility piping to pass from room to room or between floors. If historical renovations or new construction did not allow access for these penetrations, then access was likely made possible by flat sawing or core drilling.

Engineers working together with a contractor and their cutting crew locate reinforcement on drawings or survey the area with ground penetrating radar (GPR), locating embedded utilities to avoid damage where possible and allow penetrations without compromising the structure. Many CSDA members offer GPR services, with several companies specializing in it.

Specifiers require drilling or sawing of concrete for a variety of reasons: demolition, extracting concrete laboratory samples, correcting construction errors and so on. At times, drilling or sawing can provide immediate information in the field.

Core drilling as part of a slab thickness verification can provide answers in a direct and collaborative manner when confirming non-destructive test (NDT) results using GPR (ASTM D 6432). A limited number of samples are drilled or cut to verify slab thickness, providing fast confirmation of radar indications when measured in accordance with ASTM C174 Standard Test Method for Measuring Thickness of Concrete Elements Using Drilled Concrete Cores. This provides confidence in

42 | DECEMBER.18

the non-destructive measurements and thereby reducing the need to drill a relatively large number of samples.

Here are some other examples where sawing or drilling makes work in our industry more efficient, informative or even educational.

DEMOLITION PROJECT The faces of deteriorated lock walls that provided over 60 years of service were removed to a depth where sound concrete was encountered (Figure 1). The wall faces were then recast with a high-quality concrete to re-establish original dimensions. Close-line drilling of approximately 2-inch diameter by 60-feet deep were drilled approximately three feet behind the existing lock wall face. Holes were alternately filled with explosive charges to quickly facilitate removal of the wall face.

Holes had to be plumb and equidistant

concrete removal. This could have increased the need for follow-up demolition methods that may have significantly slowed project progress, increased costs and created safety issues. The expertise of the drilling contractor and their drilling consistency was a vital component of the successful, efficient and safe removal of the deteriorated concrete.

Drilling is probably not what most think of about similar locks, but it’s a precision method of concrete modification that led to the success of this project. Most CSDA contractors would be able to perform this type of drilling.

HOOVER DAM CONCRETE SAMPLE

to efficiently transmit the blasting energy between holes to ‘unzip’ the wall face upon controlled detonation. Poor drilling that resulted in greater distances between drill holes or holes that wandered too far or near to the wall face could have resulted in inefficient

During construction of the Hoover Dam between 1931 and 1936, the Bureau of Reclamation drilled very large diameter cores from the dam of compressive strength. This dam is massive, with concrete containing a maximum-sized aggregate up to nine inches.

A residual benefit of this test specimen occurred when the Bureau of Reclamation gifted a trimmed section of one of these large cores to the Portland Cement Association

(PCA). A slice from a three foot diameter core is exhibited in the PCA lobby in Skokie, Illinois (Figure 2).

Note the large aggregate (over nine inches top size) seen almost exclusively on such massive concrete structures. The larger aggregate size meant less cement was needed in the mix. A lower cement content (less expensive) led to a more economical concrete. Larger aggregate and less cement translate to less total water per cubic yard. Keeping a constant water-tocement ratio means less water is needed in the mix translating to relatively smaller drying shrinkage and a corresponding reduction in concrete cracking. A lower cement content also means a reduction in the peak heat of hydration, an important consideration to minimize thermal related cracking when constructing a structure as massive as the Hoover Dam.

Fig.3a Traffic barrier saw cut to provide visual examination of its cross-section.

TRAFFIC BARRIERS The next example could apply to any type of structure or element where additional information or confirmation is needed. We have all seen traffic barriers for instance while stuck in traffic. They help keep our cars on the road or protect us from oncoming vehicles in adjacent lanes. These barriers take a heavy beating from chemical application of aggressive deicers applied during winter, to impact damage from trucks and automobiles. Therefore, the integrity of these barriers is quite important.

However, when performance is not as expected everyone has questions. Examining the construction of typical specimens is helpful.

Figures 3a and 3b show dissected barriers to examine if the fabrication procedures of the barrier were deficient.

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

DITEQ Channel

The randomly selected sample shown in Figure 3a was dissected for examination.

The samples exhibited nearly defect-free formed surfaces. Looking beyond the surface, saw cutting revealed the concrete mix was thoroughly consolidated. The examined cut surface indicated uniform aggregate distribution and complete encapsulation of the reinforcing bars.

There are of course NDT methods that could be conducted to avoid turning such lightly reinforced barriers into swiss cheese.

@diteqcorporation

GPR (ASTM D 6432) or ultrasonic pulse velocity (ASTM C 597) would be well suited for surveying these lightly reinforced and easily accessible barriers. Refer to the list of potential tests to consider in ACI 228 Table 3 for methods to determine concrete desired properties.

When adequate samples can be obtained, sacrificial members can be used to gather additional information. It presents an opportunity to verify actual conditions and learn things not readily seen at the surface.

Fig. 3b Slices through traffic barrier exhibit uniform aggregate distribution and good consolidation around reinforcing steel maintaining proper concrete cover.

Such representative dissected samples can be shown to all parties to help the project team gain more insight or help explain existing quality and correct deficiencies in subsequently fabricated members. A cross-section may reveal if the materials, the mix proportions, construction, curing or maybe the aggressive service environment is a contributing factor to the distress exhibited.

SMALL DIAMETER CORES SHOW WHAT’S INSIDE Concrete placed through congested reinforcing steel must pass between reinforcing bars and between bars and forms.

ACI 318 addresses nominal maximum aggregate size which should not exceed: • One-fifth the narrowest dimension of a vertical concrete member • Three quarters the clear spacing between reinforcing bars and between the reinforcing bars and forms • One-third the depth of slabs The concrete must be well consolidated, but also fully encapsulate reinforcing bars to fully engage them within the member. The previous examples were relatively lightly reinforced and not a problem for filling forms, allowing easy concrete placement and access for internal vibrators for concrete consolidation.

However, some members like, nuclear related structures, sanitary tanks, transfer beams or massive foundations, may contain such congested reinforcement that concrete placement is difficult and access for internal vibrators is difficult as well. This can result in voids, rock pockets or honeycombing.

Depending on the severity of these defects, testing will be required to assess the repairability of the member.

Figure 4 shows one example of congested reinforcement, where restricted concrete placement and consolidation resulted in voided and honeycombed concrete.

44 | DECEMBER.18

The next question is, what is the condition of the interior of such a member?

If the interior is severely voided as well, there may not be a weakened case for salvaging the member and lowered confidence in future performance without problems during the intended service life.

Every case is different but it’s reasonable to assume some verification may be needed. Highly congested members are not good candidates for GPR, as the steel will send signals from closely spaced bars that interfere with one another making interpretation inconsistent or unreliable.

Other NDT methods can be considered as listed in ACI 228, but a rough first look at the condition of the interior could be the drilling of small diameter holes that avoid reinforcing steel and give at least a qualitative look at the concrete intercepted in that probe hole. Closer inspection of the core hole with fiber optic can provide information on the condition of questionable concrete.

These are just brief examples of problems that could be encountered in the field.

There are a wide variety of problems that can require the ingenuity of the engineer in assessing its extent and severity. An engineer can benefit from teaming with an

Hilti Introduces Cordless Rotary Hammer Drill Hilti, Inc. named official tool provider of Texas Rangers Hilti, Inc. is the official tool provider of the Texas Rangers. The goal of the partnership is to use the power of Hilti’s innovative products, services and software to support the construction of Globe Life Field, the future home of the Texas Rangers.

The two-year agreement includes title sponsorship of the Hilti Globe Life Field Construction site, as well as sponsorship of the Hilti Globe Life Field Observation Deck, a viewing area located on the right field upper concourse of Globe Life Park.

As a trusted partner, Hilti is involved in several key applications on the jobsite.

Structurally, Hilti’s anchors and fasteners are used in anchoring, deck fastening and waterproofing applications. Various power tools are used for drilling, anchor setting, chipping and fastening. Hilti’s firestop products will be used in floor, through penetrations, and top of wall applications.

“We are proud to be a part of the ongoing construction at Globe Life Field as the project’s Official Tool Provider. With this partnership, we look forward to continuing to bring safety and productivity to the jobsite and the hundreds of contractors working here every day,” Avi Kahn, President and CEO, Hilti North America, said. “Seeing construction progress is always exciting and it means the Texas Rangers are one step closer to calling this state-of-the-art facility home.”

To help support jobsite safety and productivity, over 600 jobsite workers gathered at the new Rangers ballpark jobsite to listen to a Hilti-led safety message. The training provided a concise overview of the silica dust regulation, with an emphasis on the benefits of making safety a priority. In addition, a Hilti mobile store is on the jobsite to facilitate product purchases and ensure a high service level with immediate support.

“We are pleased to have Hilti join the Texas Rangers and Globe Life Field family,” said Jim Cochrane, Texas Rangers Senior Vice President, Partnerships and Client Services. “Globe Life Field provides an exciting landscape for Hilti and we’re excited for them to be part of the construction process.”

The new $1.2 billion-dollar ballpark is scheduled to open in March 2020. It will include a retractable roof for climate control and shelter for fans during the hot summer months.

Pat O’Day 1948–2018 Pat O’Day had a vision. In 1977 that vision became Terra Diamond.

For over 40 years Pat O’Day and his wife Judy and the team at Terra Diamond have provided truly remarkable diamond tool products to all of North America. Pat’s passion for the concrete cutting trade generated a world-class manufacturer in the diamond tool industry.

Pat genuinely cared about his employees on and off the clock. He empowered them to contribute and improve the manufacturing process, and he gave people the opportunity to take the reins and then got out of the way. He would also cover your back if needed.

His gift was giving his employees the liberty to function in their job and truly excel. Community involvement was important to Pat and he often found ways to give back. One of his passions was the Adopt a Native Elder Foundation, which provides food and support to over 550 Navajo Elders living in poverty on the Reservation.

The O’Day’s would make trips to the remote areas to deliver food, firewood, and clothing to the Elders. Pat always looked forward to the Navajo Rug Show & Sale each year, which gave these indigenous people a chance to sell their beautiful wares and show off their immense talents. If you take a moment to look up the word “genuine” in the dictionary, you’ll find that means O’Day several things. It means actual, true, sincere, free from hypocrisy or pretense.

Pat O’Day was truly a genuine human being and the world is a better place because of him. Pat O’Day, husband of CSDA Past President Judy O’Day, passed away in November following a brief illness. Our thoughts and prayers are with the O’Day and Terra Diamond families.

Director’s Dialogue

What’s In It for Me?

PATRICK O’BRIEN Executive Director

A

contractor recently told me that he doesn’t see what value CSDA provides that he can’t get on his own. He felt that his own group offered all that they needed to succeed in business. That got me thinking about the age old question “What Has the Association Done for Me?” An association like CSDA has to provide value to members. So what kind of value can CSDA provide?

The standard response that has been developed and refined over many years is to offer a range of benefits that CSDA offers such as Safety Manual/Handbook, Toolbox Safety Tips, Safety/Training DVD’s, training courses, industry promotion through Concrete Openings magazine, websites and OSHA silica leadership. These benefits have certainly aided CSDA in its growth from under 200 to over 500 companies with an outstanding revenue increase of 1,000% to $1 million.

Will this approach work going forward? I think not! Many associations will continue to cling to the old model because it made them successful. It will take innovative new thinking and rapid response to new challenges to create a revolution, not just of CSDA but the whole construction industry.

Retail is an example everybody may be familiar with. Physical stores where customers make purchases fast and conveniently is disappearing. Many retail stores failed to adapt and effectively compete with online retailers that have utilized advances in technology to offer purchases anywhere, anytime and related up-selling. The landscape is changing dramatically and while you can say that your business isn’t affected, it will be at some point in the future. It is only a matter of time.

64 | DECEMBER.18

Don’t get me wrong, sawing and drilling contractors have changed in many ways from the early years. Contractors now offer services such as selective demolition, removal, floor polishing and ground penetrating radar imaging to name just a few. The accelerated pace of change is what will be different in the future.

The digital revolution has also changed the way members share and get new information to help them operate their businesses and communicate with their customers and employees. So for CSDA, and other associations, the meetings and conventions they organize that brought members together might well change as new methods to communicate are brought into the picture.

But while change can be challenging it also opens the door to opportunities. Changing the future of an industry can be overwhelming for an individual company. But what can CSDA, with member assistance, do to be the change agent for the industry? Despite how successful you may have been in the past your legacy business practices and processes will need to change, and make those changes more rapidly now than in the past.

This is my challenge to the contractor who didn’t think CSDA could do anything for them. Can we all work together today for a better future tomorrow? How can this partnership benefit not only your company, but your industry as a whole? Should CSDA organize a brainstorming session at the 2019 Convention in St. Petersburg next March 11-15? I hope this Director’s Dialogue has made you think and would like to hear any of your thoughts.
