President’s Page

JACK SONDERGARD CSDA President

s I write my last President’s Page, I want to highlight some of the things that I believe CSDA has and will continue to provide for its members. With respect to our employees, CSDA provides industry specific training, utilizing best practice standards with an ever watchful eye on safety. This helps promote longevity and diversity for our employees while providing a livable wage. We need to be aware of the environmental impact of our industry. Again, CSDA helps keep employers aware by providing industry standards on work and how it affects our environment and employees, especially concerning silica. We need to be mindful of the need to sustain our environment through the practice of recycling and remaining cognizant of our responsibilities to conserve renewable resources and especially those non-renewable resources. CSDA promotes consistency by our commitment to reviewing, creating and following standards and specifications in our industry. We remain consistent through our training program, ever improving our employees’ skill and growing with the latest in technological advances. CSDA itself bears witness to consistency by maintaining its governance by an elected Board of Directors since its inception in 1972. People sometimes ask what do I or what can they receive as a member of CSDA. I have been an active member of CSDA for the last 22 years. I always say and truly believe that I have received so much through my membership, committee work and Board activity. CSDA helps promote your company’s professionalism by offering the industry’s best training, the certified operator training and even Company Certification.

Our association has industry wide legitimacy as other stake holders have recognized our commitment to safety and our adherence to best practice standards. We have an added value through our relationships with the International Association of Concrete Drillers and Sawers, as well as direct influence with manufacturers through our shared experiences which have helped advance our industry. It has been my privilege to serve as President of CSDA for the last two years. As I reflect over these two years, I realize just how much both the organization and I have grown. The Company Certification Program has been completed and is available for members. There are a number of companies that have become CSDA certified companies and are willing to assist others who are ready to begin the certification process. The Board has approved the hiring of and is actively searching for a Business Development Specialist to promote CSDA to specifiers. Our Board and committees now include more young people and women, offering a more diverse perspective. For me personally, I have noticed an increased sense of confidence, both as an individual and as a business owner. Throughout my presidency, I have risen to challenges that I did not expect and have celebrated as others, too, have risen to previously unseen levels of professionalism and team membership. I have made new connections and strengthened friendships and professional relationships beyond my imagination. I want to thank Pat and his team at the CSDA office for their help and support in the past two years. As I pass the gavel onto the new President, Matthew Finnigan, I am confident that he and CSDA will continue to elevate our industry.

DIAMOND SAWING SAVES TUNNEL DAMAGED BY SUPERSTORM SANDY

INNOVATIVE CUSTOM-BUILT TRUCK GETS THE JOB DONE n October 29, 2012, Superstorm Sandy slammed the Atlantic coast of United States, roaring onshore at Atlantic City, New Jersey with sustained winds over 80 mph. At the time, it was the costliest hurricane to hit the United States (until Hurricanes Harvey and Maria in 2017) and caused over $70 billion in damage. The stormâ&#x20AC;&#x2122;s heavy rains and a high tide amplified by a full moon flooded the area with storm surges of over 14 feet, causing roadways, tunnels and the subway system in lower Manhattan to be completely underwater.

A slurry recycling system on the truck managed slurry collection and recycling while in the tunnel making the cuts.

One of the tunnels flooded was the Queens Midtown Tunnel in New York City, which connects the neighborhood of Murray Hill in Manhattan and Long Island City in Queens. The standing saltwater in the tunnel invaded the lighting, plumbing and fire suppression systems, causing water damage that was beginning to corrode away the electrical wiring, conduit and piping. The existing asbestos conduit, which was encased in concrete, needed to be removed in one encapsulated piece to avoid introducing contamination into the tunnel. Several methods for the removal were evaluated, but General Contractor Judlau OHL Group selected CSDA member Concrete Cutting Company (CCC) to get the job done, based on their proposal to fabricate a custom wall saw truck to perform the cuts. Other demolition methods such as jackhammering and robotic demolition were considered, but it was determined these would cause too much

vibration. Saw cutting with diamond tools would eliminate the vibration concern and leave a clean cut to remove the existing trench and conduit. Concrete Cutting Company wasted no time getting started on their custom wall saw truck. Working with Thor Engineering, and longtime CSDA colleague Ken Thornton, they began to design a truck that would have two cutting heads mounted onto one carriage. The two heads would allow for two saw blades to be attached at angles creating a â&#x20AC;&#x153;Vâ&#x20AC;? cut, or straight cut per cutting head. The carriage was mounted onto an 18-foot long track, each cutting head per blade operated with 75 HP off the 300 HP PTO HYD system. The truck took CCC five months to design, another month to build and an additional one to two months were needed in the tunnel to test it and work out any issues prior to the start of the cutting project.

Fire line cuts were made at five feet six inches high on the tunnel walls.

Finally, the cutting was ready to begin. The truck was positioned in the tunnel to start the first V-trench cut, a 13-foot high, eight-inch deep and nine-inch wide V-cut with 52-degree angles for the asbestos conduit removal. All cuts were made at the top of the tunnel walls, which were at a 30-degree angle. The truck made the first 15-foot cut, and when that was completed, the truck was moved 15 feet forward to start the next cut. Each cut was made so that two inches was left intact at the base of the V so the concrete-encased conduit did not fall out onto the roadway. Additionally, CCC installed three one-inch wide, 3/8 inch-thick and eight-inch long straps with a 1/2-inch stud anchor to help prevent the piece from falling. A mini excavator operated by the general contractor with an attached rig in one piece was able to remove the nine-inch wide, 15-foot long piece from the wall. The wall saw truck was designed and equipped with a compact slurry tank system that was able to vacuum slurry, clean it and reuse it on the blades, plus a 200-gallon freshwater tank. Afterwards, the slurry was disposed of offsite when the 800 gallon storage tank was full. Each section took approximately 10 minutes to complete. All functions were radio wireless remote controlled, including driving the truck and operating the saw, so the operator was able to stand safely where needed for optimal visibility. This cutting process continued, totaling 26,000 linear feet for the asbestos conduit removal. The cutting for the lighting conduit removal involved trench cuts 13-feet high, eight inches deep and 22 inches wide, again totaling 26,000 feet. The distance between light fixtures was 15 feet, with 2,400 locations. The final trench cuts were made to replace the fire suppression system lines and hydrant stations. These cuts were made at 66 inches high, 14 inches deep and 18 inches wide, totaling 7,000 feet of trench cuts. Blades for this project were provided by Diamond Tools Technology. The contractor used a 30-inch blade for the eight-inch deep V-cut and lighting trench, and a 42-inch blade for the 14-inch deep fire line trenches. The crew for CCC consisted of two men, one operating engineer operating the wall saw truck and a laborer to assist, working in six hour shifts from 10:00 PM – 4:30 AM. All equipment and work areas had to be cleaned up and equipment moved out of the tunnel by 4:30 AM each day. Over 180 total shifts were needed to complete this project. Operators followed all standard safety procedures and wore standard PPE as necessary, including hard hats, safety vests, eye protection and respirators. This job was completed over a two year period, and during the summer months, temperatures in the tunnel would reach an excess of 100 degrees Fahrenheit, so it was very important that the operators were well hydrated during that time.

The Queens Midtown Tunnel project was completed on time and within budget and CCC was awarded additional work by the general contractor. “To design and build a remote controlled wall saw truck in house, work out all the bugs in the beginning of the project and complete the project successfully was pretty awesome to be part of,” said Jeff Billington, Jr., on-site project supervisor and wall truck operator for Concrete Cutting Company. “Everyone involved at CCC did a fantastic job.” Judlau OHL Group was also very impressed with CCC. “One of the most critical activities on the project was to excavate trenches in the concrete tunnel walls. The horizontal and vertical alignment along with the depth of the cut had a very low tolerance, there wasn’t any room for error. Concrete Cutting Company was very innovative in their approach. They designed a cutting rig attached to the back of a truck that could access the elevation of the trench and also position itself at the correct angle to perform the cut. Jeff, the truck operator, was amazing. Since he was operating everything from a remote, his eye and hand coordination needed to be right on. Concrete Cutting Company was one of the main reasons the project was as successful as it was. Their success on the project has helped them gain additional work with our firm,” stated Judlau onsite superintendent Scott Valente. This CSDA contractor’s ability to provide a creative and innovative solution to a problem by using a custom saw rig and diamond tools proves that selecting a qualified and experienced CSDA contractor is the right move.

Custom Fabricated Table Created to Assist with University Research Project

• Precision was required to cut ten channels 40 feet tall, ¾ inch wide and 14 inches deep in the exterior walls of a 151-year old church in Columbus, Ohio after structural damage was caused by a lightning strike.

• The University of Tennessee’s (UT) Department of Civil and Environmental Engineering enlisted a CSDA contractor to help with a research project entitled “The Effect of Alkali-Silica Reaction on the Fracture Properties of Concrete”.

• Custom wall saw blades and aluminum blade guards were designed by the manufacturer and the contractor to reduce the weight of the saw and the chance of damage to the brick wall it would be mounted on. • Once the cuts were made, steel “T” beams were lowered through the roof into the cut channels. One-inch diameter cores were then drilled through the 44 to 63-inch thick concrete and brick wall and buttresses to secure the beams in place. • In total, 400 linear feet of wall saw cutting and 40 one-inch holes 44 to 63 inches deep were completed using diamond tools.

• UT created concrete cylinders encased in 9/16-inch thick steel casings 26 inches in diameter and 8 to 16 inches tall. Samples from these cylinders needed to be cut within 1/16-inch tolerances. • The cutting contractor created a custombuilt precision shiftable rotating table using Acme threaded rods for the positioning and an 18-inch diameter slewing bearing able to support the 600 lb. cylinders. The entire table was adjustable and could be moved left to right, had a rotating turntable in the center and featured a locking handle in the front. • Diamond cutting was the only option for this project. In the end, between 9 and 11 cuts were made on each cylinder until six 200mm rectangles were created from each cylinder.

CSDA Contractors Partner Up for Red Rock Hydroelectric Dam Project

Four-Billion Dollar Tappan Zee Bridge Demolition Project

• The Red Rock Hydroelectric Project began in 2014 with completion set for 2019, and will help supply energy to meet the growing needs of the over 18,000 customers served by the Missouri River Energy Services along the Des Moines River.

• The 62-year old Tappan Zee Bridge was retired in 2017 to make way for the new Governor Mario M. Cuomo Bridge over the Hudson River 20 miles north of NYC. Saw cutting using diamond tools was determined to be the best solution to demolish the old Tappan Zee Bridge safely and efficiently.

• Two CSDA contractors teamed up to create six openings measuring 28 feet wide by 40 to 80 feet tall through a 5-foot-diameter secant wall and four initial cavities cut into the downstream and upstream faces of the dam, each 28 feet square by 8 feet deep. A pair of 25-foot octagonal passageways through the center core of the dam, each 25 feet deep, make up the final phase of the project. • The contractors faced challenges such as making large cuts in steps, working around heavy shoring as needed to preserve the integrity of the dam and cutting underwater. • Cutting Edge Services was selected for this massive project because of their innovative techniques and flexibility of working with the precision steps needed to protect the dam. Advanced Concrete Sawing joined forces with Cutting Edge Services because of the large resource base needed for this project to be a success and because of the relationship between the two contractors forged during years of cooperation at CSDA events and on other projects.

• The project would include deck sawing for removal of the precast panels, saw cutting of the concrete and steel grid-deck, substructure wire sawing throughout the length of the bridge, core drilling of rigging holes and plunge cutting of the bridge sidewalks and dams. • It was determined that the entirety of the longitudinal cuts, more than 43,000 linear feet, in the grid-deck would require sawing at a 10-degree bevel. A custom slab saw was developed by modifying an existing Tier 4 saw. Two saws were modified and used to finish this part of the project on time, achieving between 1,100 and 1,700 linear feet daily. • In total, 46,000 linear feet of 10-degree bevel sawing were completed on the bridge deck over 3.5-inch steel T-grid, 13,000 linear feet of transverse grid deck cutting, 400 plunges through steel, concrete sidewalk and bridge dams, 8,000 square feet of wire sawing in large hollow columns and several thousand additional square feet of wire sawing were performed through the duration of the project.

Concrete Sawing Only Choice to Upgrade DFW CSDA CONTRACTOR HELPS TO REMOVE AND REPLACE 40-YEAR OLD AIRPORT RUNWAY

16 | MARCH.19

he Dallas-Fort Worth International Airport (DFW) is the ninth-busiest airport in the U.S., with nearly 1,000 flights arriving and departing daily serving over 69 million travelers each year. Aircraft take off and land from seven runways, all of which are the original runways from the airportâ&#x20AC;&#x2122;s construction in 1973. Airport officials determined that Runway 17C-35C was in need of replacement, and a CSDA contractor was chosen to provide a solid surface for takeoff and landing.

General Contractor Austin Bridge & Road headed up this massive project. Over 115,000 square yards of runway and taxiway needed to be removed and replaced without damaging the adjacent runways or damaging the substructure. This included replacing the Portland Cement Concrete (PCC) keel along with some taxiway replacements for a total shoulder reconstruction. Austin Bridge & Road called on CSDA member Diamond Drilling & Sawing Company of Denver, Colorado to assist with the runway removal and replacement. Non-destructive testing methods were used by DFW officials to determine that there were many damaged concrete panels on the runway in need of repair. Airport runways are costly and logistically challenging to shut down, so a method to quickly and efficiently remove the damaged runway sections was needed. Concrete sawing with diamond tools was the chosen method, as this method would protect the underlying structures and base under the Portland Cement Concrete Pavement (PCCP) from damage. Additionally, sawing the runway into sections that could then be removed, allowed the damaged sections to be removed quickly and would not require the base material to be replaced. The sawing portion of the project commenced on May 24, 2018. The first step in this process was to cut the PCCP into sections that were able to be removed by the general contractor. These sections measured 8.3 by 8.3 by 1.5 feet and weighed approximately 16,000 pounds. Husqvarna 7000, Husqvarna 99HP and Lissmac 138HP Diesel slab saws were used to

make these cuts. Blades ranged from 20 to 48 inches and were purchased from Diamond Products and Lissmac. Once the sections were cut, they were removed by excavators. All slurry on the jobsite was removed using vacuums. After all cut sections were removed, the general contractor was able to pour the new PCCP slabs. Diamond Drilling & Sawing Company (DDSC) then performed green cutting with

When needed, existing joint sealant was removed in areas of the runway that had not been removed and those joints were re-sealed with Crafco Mastic One material. In total, this project totaled 4,400,000 inch-feet of slab sawing, 17.5 inches thick. Sixty thousand linear feet of new joints were widened and sealed, and 160,000 linear feet of existing joints were resealed. The project took about 8 months, concluding at the end of January 2019. The project was completed within the project time and budget. DDSC was awarded additional work in the form of a change order and was requested to provide additional quotes for extra work on the project. Other methods considered for removing the damaged portion of the runway included using hydraulic hammers on excavators or eight-foot mega stompers, but both of those methods Cut runway sections ready for removal. would have caused damage to the sub-base materials and could have damaged adjacent PCCP that was designated to remain in place.

Atlanta Runway Project Paves the Way for a New Standard in Concrete Removal In 1999, a CSDA contractor was tasked to assist in removing a 9,000 foot runway at the Hartsfield Jackson International Airport in Atlanta. The job involved sawing 6 million inch-feet of concrete and removing 20,150 concrete panels averaging 16 to 22 inches thick. The cost per day of having a major runway shut down was $500,000, so it was extremely important to compete this project quickly and efficiently. Traditional demolition methods for removal would have been initially less expensive at

$35-$39 million, but with a 6-month timeframe, the cost of having a runway shut down for that length of time would have exceeded $75 million. Operators from all over the country converged in Atlanta to work together to make this project a success. In the end, over 213,000 tons of concrete were removed, with each of the panels weighing 21,150 pounds, and over 6 million inchfeet of cuts were made. This removal technique allowed 97 percent of the subbase to be utilized for the new runway and the project was completed two days ahead of schedule.

used to control silica dust and crews had to be vigilant to the weather—sawing operations had to be suspended when there was lightning in the area. Clay Stark, Senior Project Manager for Austin Bridge & Road, said the general contractor was thrilled with the results of the project. “Diamond Drilling & Sawing Company did a fantastic job on the demo sawing. They also helped us out by being able to perform the joint sealing of the new concrete,” he commented. This isn’t the first time a CSDA contractor has been called in to replace a major airport runway. In 1999 at the Hartsfield Jackson International Airport in Atlanta, Georgia, 9,000 feet of runway was removed and replaced in 34 days, a job that at the time was deemed impossible (see sidebar). When time, precision and accuracy are needed, these CSDA contractors have shown that concrete sawing with diamond tools is the best way to get the job done. Travelers in and out of the Dallas-Fort Worth area for years to come will benefit from the quality of the new 17C-35C runway, thanks to Diamond Drilling & Sawing Company.

Customized Fleet of Robots Takes Down Shopping Mall CSDA Contractorâ&#x20AC;&#x2122;s Arsenal of Robots Provides the Best Solution

echnology in construction has introduced methods of modifying and demolishing concrete structures with such precision and to such strict tolerances that operations in other parts of the same building are able to continue, even hundreds or thousands of feet up in the air. One of the most exciting and promising technologies has been the introduction of remotecontrol and robotics to construction. Both have made jobsites safer for operators and bystanders, allowed for construction and demolition to take place in confined, restricted and unsafe spaces and allowed operators access to areas they may have otherwise not been able to reach.

In late 2017, the old three-level Sears department store, part of an open-air shopping mall in Oak Brook, IL, needed to add a floor as part of a multi-use redevelopment, while still allowing for the rest of the mall to remain open. The General Contractor, Graycor, was tasked with increasing the height of the building and determined that they would need to remove two floors first, then add three to get to the desired height. The first of many challenges on this project was that the area under construction was surrounded on three sides by the active shopping mall. Traditional demolition methods could not be used, as any falling

concrete would damage the remaining floor and could create dangerous vibrations though the rest of the building. Concrete cutting was another option, but due to the subzero temperatures of as low as -40 Fahrenheit, the risk of freezing water during cutting operations was determined to be too significant. Therefore, it was determined that crushing the concrete using the demolition robots was the best choice for this job. Alpine Demolition, the demolition contractor hired by Graycor, contacted CSDA member Interstate Sawing Company of West Bend, Wisconsin. Interstate has developed a reputation for holding one of the largest fleets of demolition robots in the country and can customize these robots in-house to fit the specific needs of each job. Another challenge on this job was that there was a 21-foot distance between floors, and each floor had a 7,000 pound weight limit. There are no demo robots on the market currently that weigh less than 7,000 pounds and have a 21-foot vertical reach. So, Interstate began by customizing their fleet of Brokk and Husqvarna demo robots that weighed less than 7,000 pounds with attachments that would meet the 21-foot vertical reach requirement. Noise restrictions, due to the surrounding shopping mall and residential development, required that instead of demolishing with impact hammers, the concrete would be silently crushed and then removed by the general contractor. This method would still cause concrete to fall on the suspended floor, so crane pads

were used to protect the existing floor that was to remain in place. Crushing the concrete also prevented the vibration that impact hammers would produce. Interstate used a fleet of five demolition robots on this project. Four robots were manufactured by Brokk, including the 110, 160, 260 and 280 models while the fifth robot was manufactured by Husqvarna, the DXR 310. All these robots with attachments weigh less than 7,000 pounds, but their reaches before modifications range from 130 inches to 197 inches â&#x20AC;&#x201C; short of the 252-inch requirement of this job. So Interstate customized two of the robots, the Brokk 260 and Brokk 280. Interstateâ&#x20AC;&#x2122;s maintenance and fabrication division customized two additional arms for these robots, allowing them to extend their reaches by five feet, giving them maximum reaches of 21 feet 4 inches. With the additional attachments, each customized robot weighed about 8,500 pounds and the additional weight was distributed with track pads. Interstate started with four operators on the job, but quickly realized they were crushing the concrete faster than it could be removed. So, they split the crew into two 10-hour shifts, with two operators on each shift to make the process as efficient as possible. The two customized robots were primarily used, while the other three were kept on the jobsite to tackle any specialty needs or confined space areas. They were also useful as backup in case there was an issue with any of the other robots. Safety and environmental concerns were a major aspect of

Two robots were operating at the same time during each 10-hour shift. The area was surrounded on three sides by an operating shopping mall.

Crushing instead of breaking the concrete up with impact hammers reduced vibration that could damage existing structures that were to remain in place.

this job. Operators were working at significant heights and at the edge of a sheer drop-off, so all on the jobsite were required to wear safety harnesses and standard PPE. This job was done during a very cold Midwest winter, so not only did operators need to dress appropriately to stay warm, water usage was limited due to concerns of water freezing during operations. In all, over 150,000 square feet of concrete was crushed and removed to create space for the new floors to be constructed. Crushed concrete was pushed off an old stairwell with S70 Bobcats into a basement opening where it was then removed by the general contractor. The job was completed on time and within budget. Interstate owner and President Duke Long stated “We were extremely satisfied with how this job turned out. The process we developed worked beyond what we even expected it would. Our customer was ecstatic with the efficiency of this job.” Both the general contractor and the demo contractor were also extremely happy with the outcome of the work done by Interstate. John Moore of Alpine Demolition stated “Duke and his team were an invaluable asset to the success of this project. We presented a challenge and they fabricated the answer. They came prepared with not only Plan A, but Plan B, C and D.” Interstate was chosen for this job for their ability to not only have this fleet of robots onsite, but also for their ability to customize the robots for this specific job. Their creativity, hard work, dedication and ingenuity showcases the innovation and productivity CSDA members bring to jobsites around the world.

IACDS President’s Insight

JULIE WHITE IACDS President

wards season is upon us in the world of entertainment with the glitz and the glamour of ceremonies such as the Oscars all set to capture headlines around the globe. Something I’ve asked myself over many years is why we always put stars of sport, film, music and other forms of art and entertainment on such a pedestal, yet the heroes of business very often go uncelebrated. We will go out of our way to honor singers, actors and sports stars – but where is the love for our finest businesses, especially those specialty contractors like all of us who come up with amazing solutions to difficult problems every single day of the year? A few years ago, I decided to change that in my business and the effect has been very positive for my company. I am here now, making a plea to the rest of you in the industry: DON’T BE SHY! There’s often a feeling among companies – particularly in our industry – that putting yourself up for an award is somehow being flashy or seeking the spotlight for the wrong reasons. When there are contracts to win, staff to manage, train and pay, and all of the other day-to-day trials of running a business, why would anyone take time out to start putting themselves forward for awards? And that is, ultimately, the question – why do it? What value is there in putting yourself forward? What if you don’t win? Since I took over at D-Drill, our first major award win was a Diamond Award in 2011 which acknowledged an amazing wire saw project at a hospital in the U.K. to save some ceramic artwork that would have been lost without the innovation of our team. Can I hand on heart say we went on to win a stream of orders because of that win? Of course not. But the morale boost it gave our team for the fact that they had been recognized internationally for their work was

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

amazing. Added to that, it was a great addition to our marketing and sales pitches, that we were international award winners. It certainly adds credibility to everything you say about your own business. Our company and myself personally have won a string of awards since, and I have even appeared on national TV to let everyone know “concrete cutting is sexy!” What were the tangible benefits of these awards? I’ll give you one very solid example. I’d desperately been trying to speak to a major contractor who we were keen to work with, but it was proving tough. However, when I attended an event where the company’s CEO was speaking, it was he that made a beeline for me during the coffee break having seen me on TV, and it was a chance for me to tell him all about my business and what we could do for him. That wouldn’t have happened if I hadn’t been out there promoting my company’s accomplishments or said we were too busy to be entering awards. Also, if we want to recruit the next generation of people, don’t we have a duty to say what a fantastic industry we work in – that you, too, can be celebrated just like a sportsperson or entertainer? There are two prominent awards in our industry right now that you should consider – the Concrete Openings Awards and the IACDS Diamond Award. The goal of both of these awards is to recognize the work of concrete renovation companies internationally, promoting the expertise of these professionals and spreading the techniques and equipment used in concrete cutting, polishing and imaging contracts. You can review the winners of the Concrete Openings Awards in this issue, and the winners of the 2019 Diamond Award will be presented at bauma in Munich on April 11. Next year, you could be one of these winners!

Nutrition for Job Performance By Erin O’Brien

ealthy diet, superfoods, low-fat, high-protein and counting carbs – all buzzwords we have heard on television, read in books, magazines and on the internet. There is a wealth of information concerning nutrition out there that, at times, can seem conflicting and often confusing. So who is right and what is really important when it comes to eating a healthy diet and what impact does this have on your job performance? The answers may surprise you. While healthy nutrition can be a confusing subject, the basics are not. Yes, there are fad diets and extreme weight-loss plans that may work for some, but the easiest way to eat healthy is by following a simple plan that will not only make your body healthier, it will also improve your mood, raise your energy level and keep you healthy. All of these elements contribute to better job performance. People who consistently eat a healthy diet—not just cutting calories—reduce their risk of cardiovascular (heart) disease, cancer and other diseases and infections. Body weight is often lower, reducing stress on muscles and joints and healthy eaters fatigue less easily. A healthy diet also contributes to an efficient immune system and better overall health. The basics of a healthy diet are made up of five main components: carbohydrates, protein, fats, vitamins and minerals. Carbohydrates are the body’s fuel source and are made up of two types: simple and complex. Simple carbohydrates give the body short, quick bursts of energy and come from foods like fruits, juices and milk. Complex carbohydrates can be stored in the body for longer periods of time to be used as energy. Examples of complex carbohydrates are whole grains, pasta, bread and vegetables. All forms of carbohydrates are broken down by the body into glucose, which is then converted into energy. Protein is responsible for building and repairing muscles, ligaments, tendons and other tissues. Protein is not a significant energy source, and excess protein will be stored as fat.

28 | MARCH.19

Fats are a concentrated energy source and are also used for cell function, protection of vital organs, supply essential fatty acids and are used to transport vitamins throughout the bloodstream. There are three main types of fats: trans, saturated and unsaturated. Trans fats are usually added during the cooking process, often by frying and should be avoided, as they raise triglycerides and LDL (bad) cholesterol. Saturated fats from meat, dairy and some oils also increase cholesterol and therefore risk of heart disease. They should be consumed sparingly. The two types of unsaturated fats, mono and poly, are considered “healthy” fats and lower cholesterol levels and raise HDL (good) cholesterol. Polyunsaturated fats come from vegetable and fish oils, while monounsaturated fats come from olive oil, peanut oil, avocados and most nuts. Vitamins and minerals provide no energy, but are important components that help support the body’s essential functions. While every person is different, the same general principle applies. If more calories are consumed than burned, the person will gain weight. If more calories are burned than consumed, the person will lose weight. Younger

and active people will require more calories daily, while older and sedentary individuals will require less. In general, men will need to consume more calories than women. See Figure 1 for more information about daily caloric intake. Again, these percentages are dependent on each individual, their age and activity level. Men typically need more protein than women, while active individuals will need more carbohydrates than sedentary people. A healthy diet might start with a good breakfast. Job performance will suffer if breakfast is an afterthought and comes in a greasy bag from a fast food restaurant. Breakfast should be high in carbohydrates for energy and high in protein. This helps keep hunger at bay until lunchtime. Easy healthy breakfast options include: oatmeal with fruit, whole-wheat toast with peanut butter and jelly or an English muffin with peanut butter. Natural fruit juice with few or no added sugars, tea or milk are good beverage options. Lunches and dinners should include a high percentage of protein, some carbohydrates, and lots of fruits and vegetables. Lunch needs to keep you full until dinner, so protein is a priority. A reasonable amount of carbohydrates should be added to give you energy. Lunch is also an easy place to add fruits and vegetables, possibly with an apple and peanut butter or carrot sticks and hummus. Dinner could include anything

grilled (chicken, pork or fish) and a serving of vegetables, such as a salad or steamed vegetables. Dinner should be light on fats and heavy sauces or dressings. The term “superfoods” is used frequently, but with good reason. It usually describes foods that are not only healthy, but also contain an abundance of nutrition. These foods should be included in your diet as much as possible. Black beans - low in fat and packed with fiber and protein Broccoli - low in calories, high in vitamin A, vitamin K and sulforaphanes, which protect against stomach, lung and breast cancers Green tea - high in antioxidants and protects against viruses, infections and cancers Kiwi - the most nutritionally dense fruit, contains many vitamins and minerals Mackerel - high in heart-healthy omega-3 fats (good fats) and low in mercury Pork tenderloin - low in fat and calories, high in vitamin B6 Swiss chard - similar to spinach, high in vitamins A and K Walnuts - high in omega-3 fats Anyone will benefit from a heart-healthy diet that includes whole grains (providing fiber which lowers cholesterol), healthy fats (monounsaturated and omega-3) and lots of fruits and vegetables. Here are some examples of heart-healthy foods: Fish - especially salmon, mackerel and herring, which all contain omega-3 fats Cooking oils - olive, sunflower, peanut and sesame oils all contain high levels of monounsaturated fats, which lower cholesterol, and vitamin E, which lowers LDL (bad) and raises HDL (good) levels Fruits - contain fiber, phytochemicals and lycopene, all of which lower the risk of developing cardiovascular disease Dark, leafy greens - spinach, kale, greens, arugula, Swiss Chard and bok choy all contain folate (a mineral) which decreases heart disease risk Nuts - peanuts, cashews, almonds, walnuts and others all contain fiber and omega-3 fats which decrease triglyceride levels as well as contain monounsaturated fats, which decrease LDL levels and raise HDL levels Eating a healthy diet does not need to be complicated, expensive or time-consuming. The best plan is to take one step at a time, gradually making a permanent lifestyle change. The benefits of improving your health far outweigh any negatives, such as extra time or

Safety Counts

OSHA Liability 2019—Merrily We Roll Along By Mark A. Lies II

s 2019 gets underway, it is important to look back at what occurred in 2018 and hopefully learn from events and modify responses to scenarios that are likely to arise this year. This article will discuss several of the more salient compliance issues likely to arise in 2019 and provide recommendations. OSHA ENFORCEMENT IN 2018 In 2018, OSHA essentially continued to operate as it had during the Obama Administration since there was no Assistant Secretary of Labor for OSHA appointed by the President and approved by Congress to replace Dr. David Michaels. As a result, the career OSHA bureaucrats continued to operate as they had in the past. For those employers with nationwide operations, it was very common to see in 2018 that the OSHA regulations were being enforced unevenly or inconsistently from one Regional or Area Office to another because there was a lack of central direction from Washington. This inconsistency was further complicated by the fact that OSHA continues to experience significant numbers of retirements of career Baby Boomers at the Area and Regional Office levels, as well as in the Solicitor’s office which prosecutes the citations at trial. This inconsistency is also evident within the State Plan OSHA Programs. An employer can expect to be treated with very different interpretations of the underlying Federal OSHA regulations depending on whether it is cited, for example, in Indiana, Michigan, Minnesota, Nevada, Washington and other states. Often, the State Plan regulations do not recognize Federal interpretations of Federal regulations or case law from the OSHA Review Commission or Federal courts, creating further uncertainty. Employers also need to be aware that State Plan OSHA programs have or are developing their own regulations that may create additional compliance duties.

34 | MARCH.19

2018 OSHA EXPERIENCE The following discusses areas of immediate concern in 2019 based upon 2018 occurrences: OSHA Inspections: Failure to become aware of the rights of OSHA, the employer and employees during onsite inspections. Many employers lack basic understanding of the process, especially OSHA employee interviews which are the source of 60-70% of citations. Since employers are frequently unaware of these rights, they never inform their employees of these rights or prepare their employees for the interviews or consider “debriefing” them after the interviews. Attached to this article is a summary of the process and those rights. Similarly, many employers do not know what documents they are required to maintain and produce for OSHA and they produce documents containing information that is outside OSHA’s authority or the proper scope of the OSHA inspection which results in citations. More serious is the fact that employers many times will produce documents that are “legally privileged” from disclosure because the employer has engaged legal counsel and, as a result, waive important legal privileges for documents, including post-accident investigation that were done under the

direction of legal counsel. A summary of those documents to which OSHA may be entitled based on the scope of the underlying inspection is attached. OSHA Log Production: During OSHA inspections, the agency will typically request the OSHA 300 Log, Form 301 and Form 300A. Many employers are unaware that regulations require production of these documents within four hours of the request. If they are not produced within this timeframe, or OSHA specifically confirms that it waives the requirement, the employer will receive a citation with a monetary penalty. In some jurisdictions, OSHA has cited employers with penalties up to $12,000 for not providing the Log documents in a timely fashion. OSHA 300A Submission: On or before March 2, 2019, certain employers are required to submit their 300A injury and illness data electronically to OSHA. The directions for submitting the data are available on OSHA’s website (https://www. osha.gov/injuryreporting/). OSHA Logs are maintained based on individual worksites or “establishments” and not upon the entire employer’s workforce. Only a small fraction of establishments are required to electronically submit their Form 300A data to OSHA. Establishments that meet any of the following criteria DO NOT have to send

their information to OSHA. Remember, these criteria apply at the establishment level, not to the employer as a whole. • The establishment’s peak employment during the previous calendar year was 19 or fewer, regardless of the establishment’s industry. • The establishment’s industry is on the list, regardless of the size of the establishment. (The list is available on OSHA’s website.) • The establishment had a peak employment between 20 and 249 employees during the previous calendar year AND the establishment’s industry is not on the list. POST INCIDENT DRUG TESTING In 2018, OSHA modified its previous policy which significantly restricted an employer’s rights to conduct post incident drug testing. For years, OSHA’s position on post-incident drug testing confounded employers, and employers faced complicated questions in the stressful hours following workplace safety incidents involving accidents where there had been employee injury. The Standard Interpretation now clarifies that “most instances of workplace drug testing are permissible,” including: • Random drug testing • Drug testing unrelated to the reporting of a work-related injury or illness • Drug testing under a state workers’ compensation law • Drug testing under other federal law, such as a U.S. Department of Transportation rule • Drug testing to evaluate the root cause of a workplace incident that harmed or could have harmed employees. If the employer chooses to use drug testing to investigate the incident, the employer should test all employees whose conduct could have contributed to the incident, not just employees who reported injuries Accordingly, employers may lawfully implement, random drug testing programs, DOT drug testing programs, drug testing programs under a Collective Bargaining Agreement, and post-incident (also “postaccident”) drug-testing programs. Postincident drug testing should be conducted consistently on any employee whose conduct may have contributed to the accident, and not merely the employee who was injured in an accident. For example, if a forklift operator collides with a pedestrian and injures the pedestrian, both the operator and pedestrian should be drug tested. OSHA reiterated that

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

employers may not use a post-injury drug testing program, which the Agency would view as retaliatory, to discipline an employee solely because the employee sustained injury. Discipline merely for sustaining a workplace injury may also expose an employer to worker’s compensation retaliation claims. Any discipline should focus on violation of the employer’s policy prohibiting an employee from using drugs or being impaired, as well as the violation of safety policies, and not on the fact that the employee sustained an injury.

EMPLOYER SAFETY INCENTIVE PROGRAMS The Standard interpretation also reverses course on the 2016 retaliation regulation’s prohibition of safety incentive programs. With limited adjustments, OSHA now permits employers to bring back reportingbased safety programs, which the Standard Interpretation lauds as an “important tool to promote workplace safety and health.” The Standard Interpretation permits a program which offers a prize or bonus at the end of an injury-free month. OSHA’s new position thus permits employers to bring back cash bonuses or the much-criticized monthly pizza

continued

party. The Standard Interpretation also permits programs that evaluate managers based on their work unit’s lack of injuries. However, to lawfully implement such a safety program, the employer must implement “adequate precautions” to ensure that employees feel free to report an injury or illness and are not discouraged from reporting. OSHA’s primary concern is discouraging employees from reporting injuries because they do not want to forfeit the prize or other benefit. According to OSHA, a mere statement that employees are encouraged to report and will not face retaliation is insufficient. Employers need to undertake their choice of additional “adequate precautions,” which will undercut any inference of a retaliatory motive, such as: • An incentive program that rewards employees for identifying unsafe conditions in the workplace • A training program for all employees to reinforce reporting rights and responsibilities and emphasizes the employer’s non-retaliation policy • A mechanism for accurately evaluating employees’ willingness to report injuries and illnesses • A statement that the employer will investigate the accident and if the investigation reveals that the accident was not due to the employee violating the employer’s safety and health policies, the prize or other benefit will be reinstated The Standard Interpretation thus permits and encourages safety incentive programs that reward employees for identifying unsafe conditions in the workplace. A second precaution, a brief training on reporting illnesses and injuries, would be simple for employers to conduct and add to onboarding orientation for new hires. The “mechanism for accurately evaluating employee’s willingness to report” could be a regularly scheduled, random questionnaire on employee willingness to report injuries and illnesses. Accordingly, if employers adopt these low-burden precautionary measures, they may now bring back or adopt safety programs that are popular and effective at reducing workplace injury rates.

Fall Protection Employers are required to protect employees against the hazard of a fall. OSHA has extensive regulations requiring the use of fall protection (guardrails, safety nets or personal fall protection) when employees perform elevated work. This year saw many tragic accidents where employees fell from roofs, mobile equipment, interior structures, machinery, truck trailers, towers and other elevated equipment.

PARTICULAR HAZARDS Some of the more frequent hazards encountered in 2018 include: Lockout Tagout (LOTO)/Machine Guarding In most cases, employers are required to have a written LOTO procedure for each piece of equipment where energy sources must be de-energized prior to performing servicing or maintenance. In 2018, many employers were found to be lacking these procedures, they were not current as to the correct procedure or employees were never trained how to use them. Other employers did not conduct the required annual periodic inspections and maintain the required documentation. Regarding machine guarding, many employers failed to conduct a job hazard assessment (JHA) to identify whether guarding was necessary or adequate or, worse, failure to enforce keeping guards in place. As a result, there were many fatalities and amputation type injuries.

Hazardous Substances (Employee Right to Know) Employers must provide Hazard Communication training to employees working with hazardous substances and document such training. There are also requirements for labeling. The failure to provide this training has resulted in employee exposure to hazardous chemicals or other substances that may be in the worksite. Employers are cited for failing to train employees about how to understand the Safety Data Sheet (SDS), where they are located and how to access them. Employers also failed to maintain an inventory of the SDS for all hazardous substances at the worksite.

Powered Industrial Trucks (PITS) Employers cannot allow employees to operate PITS unless and until they have been trained, authorized and certified with supporting documentation. Employees must also be recertified every three years and retrained after an accident or near miss. Employers were cited for failure to train the PITS operators or to enforce the safe operation of the equipment. In addition, many employers allowed outside contractors or temporary employees to operate the equipment without training. PIT accidents frequently result in serious injury or death.

Multi-Employer Worksites Another significant liability that many employers are unaware of is the “multiemployer worksite” doctrine. Multi-employer worksites exist where there are several employers at the same worksite. Each employer has OSHA duties not only to its own employees but also to other employer’s employees at the site depending on whether the employer is one of the following: • employer who creates the hazard for other employees • employer who exposes the other employee to the hazard

Personal Protective Equipment (PPE) Employers are required to conduct a written hazard assessment to identify hazards which Type of Violation

require PPE (gloves, eye protection, foot protection, etc.), to certify the assessment and certify that the PPE was provided. In addition, employers must enforce the use of PPE. Many employees sustained serious injury because PPE was never provided, employees were not trained how to use it, or the employer did not enforce its use.

on an annual basis. While no employer wants to accept citations that are not factually or legally correct, but sometimes do so for expediency, employers must be aware that every citation that it accepts (including Other-Than-Serious) can be used as a basis for Repeat citations in the subsequent five years if there is another “substantially similar” violation or for a Willful violation. In 2019, OSHA revised its penalty structure with increases in the penalty amounts.

•

employer who is responsible to correct the hazard to which the other employees may be exposed • employer who has control over the worksite or a hazard, typically the owner of the worksite, a general contractor or a subcontractor with a sub subcontractor. Many employers are totally unaware of these liabilities and fail to take appropriate action to protect other employees who may be at the worksite, including independent contractor employees and temporary staffing employees. GENERAL DUTY CLAUSE— EXPANDING LIABILITY In addition to its formal regulations, OSHA can site employers for “recognized hazards” likely to cause serious injury or death. To be compliant, an employer must be vigilant to such hazards and develop feasible means to protect its employees. There has been considerable OSHA citation liability for hazards, including: • Workplace Violence (several states have developed regulations to address7,313x4,625_floor this hazard)saw_MC570.pdf 1 13.07.2018

•

Heat Illness (heat rash, heat cramps, heat exhaustion, heat stroke) • Electric Arc Flash/Blast (exposure to energized electrical equipment) • Ergonomic Stressors (repetitive motion, awkward motions, extreme temperature environment) Employers are required to maintain their OSHA 300 Log for such illnesses when recordable. The General Duty Clause also requires employers to investigate each incident and take feasible corrective action. OSHA INFORMAL CONFERENCES Many employers fail to adequately prepare for the OSHA informal conference after citations are issued. Unfortunately, many let the typical fifteen (15) working day period (State Plan program time periods may vary) to attend a conference or file a written contest or appeal to the citation and it becomes a final court order. In other instances, employers do not adequately prepare for the conference to assert their factual and legal defenses and when they attend, they cannot articulate the defenses 10:10:10 and OSHA is not motivated to vacate or

amend the citations. Worse yet, many attend and make “admissions” of liability which support the violation. Many employers are unaware that every citation which is accepted creates a five year period going forward during which any subsequent violation during that period which is “substantially similar” can result in a Repeat Citation with significant penalties. In so doing, they accept citations which should have been contested for expediency and have no conception of the potential legal minefield that may be created in the next five years. Hopefully, we all can learn from our own unfortunate experiences or those of others in 2018 to avoid repeating errors which result in accidents or regulatory liability to avoid these liabilities in 2019.

Polishing Concrete Floors with a Power Trowel —The WHO, WHAT, WHERE, WHY and HOW By Ryan McBride

s most of us know all too well, the concrete polishing industry changes often and rather quickly. If you don’t stay up-to-date within every six months or so, you’re likely to lose touch with trends and developments that can affect your ability to stay competitive, or even worse, miss an opportunity to even compete in an entirely new market. World of Concrete 2019 had an outstanding turnout and good weather to boot, which made for a great showcase to highlight these ever-changing opportunities. One of the most prominent new additions to the polishing industry was polishing using a power trowel. To be fair, polishing concrete floors utilizing a ride-on or walk-behind power trowel outfitted with diamond tooling or abrasives isn’t a “new” method. The concept has been around for almost a decade. However, there has been a shift in the industry utilizing these processes and more and more contractors are realizing the appeal of saving time and creating a source of income that has otherwise been unavailable in the past. As competition continues to grow fiercely for concrete polished floors in the 10,000-50,000 square foot market, contractors look for advantages and growth opportunities. Ride-on power trowel polishing can offer solutions in both of these categories. TIME SAVINGS The largest advantage of power trowel polishing is time savings. This is crucial to most contractors, as labor burdens can affect the bottom line quickly with unforeseen project delays. Most power trowel systems are estimated to provide as much as 10,000 square feet per day for a turn-key five- or six-step polishing process. This is massive compared to traditional grinder methods providing approximately 1,000-2,000 square

38 | MARCH.19

feet per machine per day. For example, one skilled operator on an eight to ten-foot riding power trowel can produce 10 times the finished floor compared to an equally skilled operator equipped with a 32-inch grinder. Even if four large 32-inch grinders are on the same project, the skilled operator with the power trowel machine still has a 50 percent advantage to produce more work. INCOME POTENTIAL The other major advantage of power trowel polishing systems is that it appears to have opened up an entirely new market for the polishing industry; very largeformat projects that are in the 100,000 to 1,000,000 square foot range. These types of floors would normally receive a light scrub and densification at best, or possibly a low-cost sealer. With the speed and lower labor cost advantages of power trowel polishing, polishing contractors are able to offer economical floors with a low-gloss appearance, better long-term performance

and a lower cost of ownership to owners of large warehouses than “sealed” floors. LIMITATIONS In fairness, we must acknowledge the limitations of power trowel polishing systems. Currently, they are all wet grinding systems with some restrictions on aggregate exposure and high “gloss” finishes. Most power trowel systems lack the weight and/ or tooling pressure to expose aggregate on a consistent basis like traditional grinders. Also, the final results of a power trowel polished floor often can’t compare with the aesthetics of a traditional high-quality ground, honed and polished floor. But then again, these types of polished floors aren’t utilized in an average industrial/manufacturing sector for concrete polishing market on a day-to-day basis. APPEALING TO CONTRACTORS When thinking about who could use and benefit from this technology, of course the first group that comes to mind would be polishing contractors. They already understand how

polishing a floor works, they know the steps involved and time required. Power trowel polishing would definitely open up a new area of revenue for this contractor. But who else could benefit? Polishing contractors that are used to providing higher-end floors with better aesthetics such as high-gloss and high DOI (distinctness of image) can integrate power trowel systems into their process and still realize some of the labor and time savings. For instance, one could utilize traditional grinders for the initial grinding steps to flatten the floor surface and/or expose large aggregate. Then, they could send that crew ahead to another project while they bring in a one to two power trowel system to hone and prep for the final polishing, and then complete the process with traditional grinders to provide the high-gloss and DOI specified for the project. This so-called hybrid process would still save considerable time and money for the project while freeing up crews/grinders for additional projects â&#x20AC;&#x201C; all while keeping the schedule flowing smoothly. In addition to traditional and specialty polishing contractors, contractors specializing in placing and finishing concrete for large square foot projects can now offer their clientele an additional service while generating additional revenue utilizing equipment that they (probably) already own. What more could a contractor ask for? Most of the power trowel systems available today seem to be similar in concept, attaching bonded abrasive diamond tools to the power trowels in lieu of finishing blades. There are some advantages, or disadvantages depending on your perspective/opinion, to fixed or quickly interchangeable tooling drivers, passive or active planetary actions and flexibility of the diamond tooling drivers. It appears the main sought-after feature is ease and speed of tooling changes, as well as high performance of the lower grit or hybrid diamond tooling. The systems that appear to offer contractors the best results utilize quick tooling changes and flexible tool holders. Quick tooling changes are enabled through the use of strong magnets, which are fitted on the back of the tooling pad and on the driver. This makes it very easy to switch out the tooling. In addition to quick tooling changes, flexible tool holders are also beneficial as they allow the diamond tooling to flow with the floorâ&#x20AC;&#x2122;s surface. Due to the

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

span of a typical riding trowel (eight to ten foot diameters), they do not reach low spots in the floor as easily as traditional grinders. Therefore, having the flexible tooling holders is certainly an advantage when polishing floors with low floor-flatness values. FORWARD THINKING One thing is certain, if power trowel polishing was previously thought of as a fad or temporary phase, it has proven itself to

be a vital part of the economics of concrete polishing. Power trowel polishing systems will continue to be a focus for years to come as manufacturers continue to perfect their diamond tooling and processes.

PROTECTING THE ENVIRONMENT ONE CUT AT A TIME New Zealand Contractor Utilizes Technology and Planning to Upgrade Roadway

A main highway in New Zealand has been undergoing a multi-year improvement and expansion project, and in winter 2019, a section with over-water bridges in New Zealand needed to be expanded. It was determined there was only one way to complete the job quickly and safely. Concrete cutting with diamond tools would allow for pre-planning of cut sections and a fast, clean removal of roadway sections. As this series of bridges and roads also spanned a tidal creek, it was imperative that no debris or slurry

be allowed to fall into the creek, and also that no fly rock would strike vehicle traffic. The SH1 Southern Motorway on the North Island of New Zealand is part of State Highway 1, the longest and most significant road in the country. SH1 runs for 2,033 km (1,263 miles) and is primarily a two-lane single carriageway. It is an essential part of Aucklandâ&#x20AC;&#x2122;s transport network and is the primary route between Auckland, Hamilton and Tauranga. The Southern Corridor Improvements Project, which will cost $268 million

The bridge was closed at night to allow for sections to be lifted out safely without affecting roadway traffic.

Hilti wire saws were used to cut the bridge deck into 45-ton (99,208-pound) sections.

(USD$183 million) and runs for over four years, covers the stretch of SH1 from the SH20/SH1 connection at Manukau down to Papakura in the south. CSDA member A1 Kiwi Cutters & Drillers Ltd. of Auckland was selected as the cutting contractor on the Southern Corridor Improvements project by the general contractor and the New Zealand Government. Roughly four months of planning took place before any work commenced, which contributed to the successful outcome of the project. The entire project was to convert a two-lane section of motorway to a three-lane by constructing a temporary bridge, widening some existing bridges, removing other existing bridges and building a new wider bridge. The temporary bridge

was constructed first to allow for southbound traffic to be diverted while the northbound traffic was diverted to the old southbound lanes. Then, the existing northbound bridge was removed, and a new wider bridge was constructed in its place. Both north and southbound traffic was then diverted to the new bridge while the old southbound and temporary bridges were removed to allow for construction of the new, wider southbound bridge. A1 Kiwi Cutters was tasked with removing the existing southbound bridge and temporary bridge, including head stock and bridge beams. Concrete cutting was determined to be the best option for removing the old bridges primarily for environmental reasons. The bridge spanned a tidal creek, making it imperative that the creek be protected from any debris or concrete cutting slurry.

Two Hitli wall saws were used to cut along the edge of the head stock at an angle.

continued

Additionally, the bridge was located within two meters (6.6 feet) of a heavily traveled section of motorway, with residents living within 50 meters (164 feet). Traditional demolition methods would have been noisy, presented an unacceptable risk of fly rock going into the live traffic lanes and would have resulted in significant amounts of rubble being dumped into a sensitive environmental area. â&#x20AC;&#x153;Concrete cutting is quick, significant amounts of concrete are moved intact and the Super Tee sections of the bridge were able to be used on other parts of the project,â&#x20AC;? said Sam Simons, General Manager for A1 Kiwi Cutters & Drillers Ltd. The first step of the project was to setup the slurry control system. All slurry was captured and disposed of off-site. Next, the bridge deck was pre-cut using Hilti DS WS 15 and DSW 3018-E wire saws, as well as some of the bridge abutments and head stock. There were three bridge sections to be cut, each weighing 45 tons (99,208 pounds). Two Super Tee units, each weighing 117 tons (257,940 pounds), were then cut so that

they were resting on the bridge abutments and made ready for lifting out. This was done to minimize cutting when the 350- and 450-ton cranes were deployed. A1 Kiwi then installed lifting brackets that were rated to lift each bridge section. The motorway was closed from 22:00 to 5:00 the next morning to allow for the next phase of work. Because of the excessive weight of the cut sections, a double crane lift (using the 350- and 450-ton cranes) was used to rig the cut sections and lift them out. The two Hilti DS TS20-E and DST 10-CA wall saws were then used to cut along the edge of the head stock at an angle to aid in the removal of the bridge section. Once cut, the section was lifted onto the back of a transporter and removed from the site. In one shift, three bridge sections and two Super Tees had their final cuts and were lifted out for removal from the site. The second phase of the project involved removing the remaining two spans of bridge during normal working hours. Only one crane was needed because the spans were located

Collecting and disposing of slurry was of utmost importance to avoid contaminating the environmentally-sensitive tidal creek below.

42 | MARCH.19

After the bridge deck slabs were pre-cut, lifting brackets were installed for removal via two cranes.

closer to the crane and loading out could be done on the closed roadways. Additional slab sawing was completed using a Corecut CC35 slab saw. In total, 100 feet of wire sawing, 335 feet of wall sawing 18 inches deep and 110 feet of slab sawing one foot deep was completed. This project produced many challenges for the contractors. Working close to a busy motorway, precautions had to be made to ensure there was no interaction between cars, the public and operations. Furthermore, most of the work took place during a

three-day period of King Tides, the strongest tidal flows. This aspect required significant planning to ensure success and safety. Absolutely no slurry or debris was permitted to enter the creek due to environmental regulations. This was managed largely by the general contractor, with input and assistance from A1 Kiwi Cutters. Another concern was that this project took place during one of the hottest and most humid summers on record in the Southern Hemisphere. It was imperative that operators stayed hydrated and avoided risking heat illness.

The two Super Tee units weighed 117 tons (257,940 pounds) each.

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

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

Corecut saws were used to help remove additional bridge sections.

It was very important that the project be completed on-time and according to plan due to the cost of using cranes and having to close the motorway. The three A1 Kiwi employees who were on site worked the hours required to keep the job on schedule, readily complied with standard health and safety protocols, kept a lookout for any environmental issues and communicated with the general contractor on issues as they arose. The contractor also kept backup wall and wire saws in close proximity on the job site in case they encountered any equipment issues, although this complication was not expected to be an issue. “A1 Kiwi invests heavily in new technology. Equipment is updated regularly which minimizes jobsite breakdowns. Part of the reason we were chosen for this job was that the general contractor realized our investment in the newest technology and latest equipment would help to guarantee the work would be completed on time,” Simons stated. The end result was 650 tons (over 1.43 million pounds) of concrete removed over the course of 12 work shifts. The project was completed according to plan and within budget. A1 Kiwi has done a number of significant concrete removal projects over the last decade. Each of the company’s employees has gone through, or are going through, the New Zealand Qualifications Authority unit standards for concrete cutting and drilling. “This gives our clients confidence that the people we send to site are competent to perform the work. The company has a structured training program so that every employee has the

opportunity to get on these technical projects that test their capability. The clients also know that they can contact staff, some of whom have 45 plus years of experience, should they have any concerns,” said Simons. REVIEW AND COMMENT ON THIS ARTICLE AT: WWW.CONCRETEOPENINGS.COM

Let’s Hire A Vet! Build Your Word-of-Mouth Network By Brig. Gen. (Ret.) Marianne Watson

re you placing job ads, but not attracting the right employees? You’re not alone if you are having this problem. In a national survey of employers by nonprofit Center For America, a majority of employer respondents cited the problem that their job advertisements are not attracting the workers they are looking for. Have you considered focusing on hiring veterans? There are many military veterans returning from overseas who are qualified, hard working and looking for jobs. But how do you find them? A good first step in word-of-mouth is finding a veteran – maybe someone already in your organization, or among your retirees and suppliers. They can put you in touch with good candidates in their veteran network. Veterans want to help other veterans find good full-time jobs. There are many effective nonprofits, state agencies and military employment transition organizations in your area that can help, so make sure to reach out to them. However, your own networking with the veteran community may be a faster way to find good candidates that match very well to your requirements and culture. Most veterans maintain close contact with other veterans through a wide range of organizations and events. They know friends and acquaintances who are looking for good jobs. They also have good instincts about who in their network would have an interest in a given job and the skills and experience to fit in well. Tapping into this network isn’t hard: start by identifying veterans among your employees, your retirees, your suppliers. Give them an up-to-date written description of the job and the qualifications so they can pass this along to their contacts and get the word out. Developing a “word of mouth” network works better when you explain to your veteran contacts why your jobs and your company offers a good fit for people with a military background. This can empower your contacts to make a good case for you. Veterans making a transition to a civilian job often know very little about most industries and less about specific companies.

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

While many veterans go online to research jobs, you should take the time to explain the aspects of your jobs and your company that should be especially attractive to veterans. Your military-friendly attributes would include: future career growth supported by training or in-house mentoring, an emphasis on teamwork and your commitment to diversity. Since veterans are accustomed to these topics while in the military, the more specific you can be, the better. There are many national veterans’ organizations that have local affiliates you can contact for referrals. Although these organizations are not specifically in the business of providing referrals, veterans who belong are always interested in helping their members find good career jobs. You can contact the local affiliates of these national organizations by visiting the national websites listed with each: •

Team Red, White & Blue: www.TeamRWB.org

The time you spend developing a word-of-mouth network among veterans will have growing benefits over the coming months. The more your veteran contacts learn about you and your company, the

more they will want to recommend candidates to you. The more you learn about the veterans you are in touch with and the issues and concerns they have, the more effectively you can gain their help. You’ll also get feedback about your jobs that will help you position them more effectively or address aspects of your offers that are turning veterans off. If you would like to learn more about hiring veterans, National Guard members and Reservists, visit our website at www. CenterForAmerica.org. You’ll find many free Guides, articles and video presentations on recruiting military candidates. Also on the CFA home page, post your jobs through the American Jobs for America’s Heroes campaign to have them distributed directly to military employment counselors where your jobs are located. To learn more about the benefits of hiring veterans and best hiring practices, attend the 2019 CSDA Convention & Tech Fair in St. Petersburg, Florida, March 13-15. Major General (Ret.) Garry Dean will speak to convention attendees about the resources offered by Center For America. Maj. Gen. Dean served as Commander, 1st Air Force, Continental NORAD Region, and AF Forces Northern, responsible for planning and executing the Air Defense of the Continental United States, the Missile Defense of the National Capital Region, and the USAF response to natural disasters in the homeland.

Brig. Gen. (Ret.) Marianne Watson serves as Center for America’s Director of Outreach and served as the Director of Manpower and Personnel at the National Guard Bureau. She was chief human resources officer of the Air and Army National Guard, responsible for leading the employment transition operations, among other functions.

Husqvarna Launches Husqvarna Fleet ServicesTM Husqvarna Fleet Services™ is a system that collects and presents data regarding a contractor/rental company’s machine fleet. It enables operators to make better decisions and unleash the full potential of a company’s productivity. Data is generated by digitally tracking each machine’s performance, runtime and job location. All data is displayed in your Husqvarna Fleet Services™ portal for further analysis. Information is transmitted through a sensor, which is attached to the equipment. In most cases, Husqvarna’s equipment has a location specifically made for the sensor. The sensor will fit on non-Husqvarna equipment as well, ensuring operators get the most out of their fleet. Once installed, a plethora of information is available. For More Information Contact: Cate Stratemeier Tel: 913-928-1442 Email: cate.stratemeier@husqvarnagroup.com W WW.

D-Drill Director Honored with Lifetime Achievement Award A leading UK figure in construction has been honored with a lifetime achievement award. Julie White – the managing director of specialist concrete drilling, sawing and controlled demolition company D-Drill – picked up the honor at The Builders’ Conference Live Awards. The Builders’ Conference is the construction industry’s trade body that provides up to the minute statistics and potential contract leads to companies across the UK.

A1 Kiwi Cutters & Drillers First in Austrailasia to Order Hilti’s New Wall and Wire Saw System A1 Kiwi Cutters & Drillers Ltd. have always been recognized within the New Zealand concrete cutting industry’s market as innovators that think outside the box when it comes to concrete cutting and meeting their client’s project requirements. So, when Hilti approached them with an innovative new wire and wall saw package, they jumped at the opportunity. The new DST 20-CA wall saw was a no brainer in Penny and Janine’s eyes and having the e-box incorporated into the cutting head was the game changer they were looking for and with the cut assist innovation included, instant productivity advantages were recognized. The new DSW 3018-E wire saw was the other talking point. Hilti’s most powerful electric wire saw, it’s capable of cutting up to eight square meters per hour. The cutting power is provided via two 15kW electric motors which move the wire over the pulleys at a speed of 35m/s. This saw will be used heavily on their larger more technical contracts due to its range of capabilities and ease of use on site. A1 Kiwi Cutters & Drillers Ltd. were the first company to order both DST 20-CA and DSW 3018-E in Australasia, and these additions add to an already large fleet of Hilti Heavy Diamond equipment within the A1 Kiwi Cutters & Drillers Ltd. stable and will provide them with further opportunities in the future.

Hilti is Raising the Bar on Hammer Drilling Hilti’s new generation of hammer drill bits TE-YX bring you faster drilling, more strength and a lifetime of productivity. Its innovative design consists of a full carbide head to drill faster in rebar with less jamming, thanks to its multi-cutter construction. The bit helix is never machined, offering a lighter weight and more body strength. TE-YX are the only SDS Max bits offering a warranty, meaning they can be replaced as long as the wear mark is visible. The TE-YX features don’t stop there; the wear mark indicates that it has the correct diameter for anchor setting. Raise your bar on hammer drilling by adding the TE-YX bits to your TE-Y SDS Max tool case. Hilti is the only brand to offer a complete value proposition in every SDS bit (SDS plus, SDS Max).

Julie, a former UK Businesswoman of the Year, was presented the award by broadcaster and host Mike Shaft during a ceremony at The Savoy in London. In announcing Julie as the winner, he said: “This award goes to someone who works tirelessly to improve the image of the construction sector and who is a shining example of how sharing best practice and knowledge can benefit everyone. With an absolute passion for what the sector should be doing to encourage more young people to consider construction as a career, she is committed to delivering the very highest standards of health and safety though a skilled workforce.” Julie White completed a management buy-out of D-Drill from her father a decade ago and has gone on to become a leading figure in the industry. Under Julie’s watch, the company has added further divisions in 2D/3D concrete scanning, floor preparation, fire protection as well as inventing a new D-Kerb machine that can cut curbs to 45 degrees in situ. She is the first woman to be appointed to a professional body for the industry, having joined the board of directors for The Drilling and Sawing Association in the U.K. and is also President of the International Association of Drillers and Sawers (IACDS) – the first woman ever to take up that post.

Husqvarna Introduces K 770 Vac Power Cutter for Dry Cutting Wet cutting is the preferred way to cut in most situations, but sometimes dry cutting is the only option. For example, when slurry may stain masonry materials, water is in short supply or when regional regulations restrict slurry. With the Husqvarna K 770 Vac, you get the power and proven qualities of the lightweight K 770 power cutter while adding the benefit of dust extraction. The power cutter features a distinct blade guard, which helps collect the dust while cutting and directs it to the hose. The flexible hose connector easily attaches to an external dust extractor, such as the Husqvarna S 26, and facilitates dust removal and containment. In addition to the blade guard, the integrated gearbox reduces the speed of the blade to optimize the removal of dust. The K 770 Vac can cut up to 4.8 inches (122 mm) - almost the same cutting depth as a 14-inch machine. Using Husqvarna’s dry cutting power cutter will help increase operator health and safety and, at the same time, give the operator a slurry-free workspace, minimizing the need for cleaning and preparing the work site.

California Awarded $187 Million for Water Infrastructure Projects The U.S. Environmental Protection Agency (EPA) has awarded $187.3 million to more than 180 California drinking water and wastewater infrastructure improvements throughout the state. The funds will be jointly shared by California’s Clean Water and Drinking Water State Revolving Fund programs (SRFs). The EPA has awarded over $5 billion to these two programs since their inception in 1988 and 1996, respectively. These federal funds support the state’s efforts to address an estimated $70.5 billion of water infrastructure needs. “These funds will be used for 183 local projects that will boost the economy while improving water systems,” said EPA Pacific Southwest Regional Administrator Mike Stoker. “Simply put, these funds help make California water safer, more accessible and sustainable as the state faces a variety of daunting challenges in the years ahead,” said Leslie Laudon of the CA State Water Resources Control Board. California’s Clean Water SRF will use over $114.7 million for a variety of water infrastructure improvement projects.

Hipertrowel Introduced by Husqvarna Hipertrowel™ is the ideal method for industrial floors from 5,000 square feet and up. Both newly poured slabs and older, pre-existing floors can be processed with the Hipertrowel™ system. The Hipertrowel™ system is a six step wet polishing process along with three optional final steps. In addition to a power trowel, a complete set-up includes Husqvarna Hiperflex TRW tool pads, chemicals, Hipertrowel™ gryo drivers, power trowel attachments, a squeegee vacuum (such as the PullmanHolt 45-20P with squeegee kit), and a hose connected to a tap. Both the Hipertrowel gyro driver and Hiperflex TRW tool pads are designed for maximum flexibility in all directions. This allows the diamond tool pucks to follow the floor surface in the high and low spots and create a homogenous salt and pepper finish. The Hiperflex TRW tool pads are easy to mount securely underneath the Hipertrowel™ gyro drivers due to strong magnets connecting the pads to the driver.

We have enjoyed and learned so much from other members of the association and have made many longlasting friendships. My wife and I have been amazed how CSDA has always stayed ahead of new and upcoming regulation changes for its members. One that is of most importance in today’s industry is the new silica regulations. CSDA and its members have been at the forefront of addressing the challenges of silica since 2003. The association has spent countless hours with OSHA to address health Jose & Katherine Ortiz Accurate Professional Concrete Cutter, LLC issues within the industry, along with other associations, to negotiate the best possible outcomes. If you are a professional concrete cutter and are striving to be better at what you do, CSDA is the association to join. CSDA has a written silica addendum to their Safety Manual which is available for purchase – it’s specifically designed to help contractors become and remain compliant. There are members from the safety and training committees who were directly involved in the creation of this program and other training tools. The hands on training that they offer throughout the year to maintain and continue all members and their employees compliant is heavenly sent.

Director’s Dialogue

A Long Time Ago … (But not in a galaxy far away!) PATRICK O’BRIEN Executive Director

t is hard to believe that I have been involved with CSDA for most of my business career. I left the military and civilian aviation industry in 1982 to work for the Specialty Materials Department (SMD), a division of General Electric. The diamond business was very secretive in those days and GE didn’t even publically acknowledge this business with a GE logo or sign on the building. The diamond manufacturing and sales business was intriguing, and the people in the industry were driven and quite interesting. SMD only hired sales and marketing people that had a technical degree and sales/marketing experience. As a new marketing manager, I had the opportunity to meet many outstanding people from around the world, and one of my first jobs was to support a then ten-year-old Concrete Sawing & Drilling Association (CSDA). CSDA was started by Les Kuzmick of Cushion Cut to represent contractors and manufacturers. The members excelled in cutting concrete and manufacturing diamond tools but needed marketing assistance to sell their message to specifiers. GE offered such assistance that eventually led to the creation of a Diamond Advantage presentation to promote the advantages of sawing and drilling to architects, engineers, general contractors and government officials. One of my first tasks working with CSDA was to develop a presentation for the World of Concrete. This proved to be more of a challenge than expected, as I knew little of the industry then and

job story info was difficult to come by. But with the help of a few dedicated leaders, field trips to job sites were organized that allowed me to learn about the business and ultimately make a presentation at the 1983 World of Concrete. Little did I know at the time that this would be the first of many presentations I would make for CSDA. My decade with GE included various sales and marketing positions, but I always enjoyed and maintained a connection to CSDA. In 1991, I left GE to start my own business and was selected to be CSDA’s new executive director. In the beginning, it seemed like a 10 year run would be an appropriate tenure. There was much to be done to advance CSDA’s mission by combining the association technical skills with fresh marketing and sales expertise. But as that 10-year mark came and went, I discovered this job was as much fun as hard work. The dedicated and friendly group of people was a plus as well. Other associations that we managed came and went, but CSDA was always special and has remained so to this day. It was a challenging opportunity to take Les Kuzmick’s 1972 idea and advance the association to the next level. During those years, CSDA has seen membership grow from under 200 companies to 500 and the budget grow from $100,000 to $1 million. Change is inevitable and so is taking CSDA to an even higher level. It’s time for me to start planning for the end of my career and time with CSDA. The future for CSDA is truly unlimited and I look forward to seeing the association moving on to that next level.
