hope all our members, contractors, manufacturers and affiliates are having a busy and profitable summer. There seems to be more than enough work out there to keep us all working day and night. I think most of us could even use a few more good employees to help catch up! It goes without saying that there is a shortage of qualified workers in most industries, and when you add in the hard work of concrete construction, it is difficult to find and keep good people. I believe one way to keep quality workers happy and proud to be an employee is to offer them training opportunities whenever feasible. Safety training is first on the list, and I would expect that most of our members are doing much of that. Other possibilities for training your employees could be first aid, forklift training, scaffold erection, blueprint reading, OSHA 10 and 30 and many others. Various training opportunities are offered at numerous venues and are usually easy to apply for and attend. CSDA also provides training options that apply directly to our work. Many online subjects such as Fall Protection and Cutting Training are available through the CSDA website. Many companies do much of their basic training using this method. CSDA also has hands-on training courses available this fall.

Classes will be held at St. Petersburg College in Clearwater, Florida for the CSDA 101 introductory series of courses on slab, wall, wire and hand sawing as well as core drilling. Classes are October 15-19. The CSDA 201 Operator Certification courses for experienced operators will be held at the same location on November 5-9. This is a great opportunity to send employees to become trained and certified by professionals in the industry. It is becoming increasingly necessary to show that your employees have proper education and training to do their jobs, so please visit www.csda.org to learn more and sign-up! The Marketing Committee continues to develop a Market Development position, who will reach out to architects and engineers to promote concrete sawing, drilling and polishing to specifiers. Our Safety Committee continues to digest new information coming from OSHA on the silica standard and will report any new information accordingly. We encourage all members to share any documentation on exposure testing that they have. We are trying to develop valid industry-wide data that every contributing company can use to spare the testing cost of each task.

hat costs four billion dollars and breaks construction records? One massive bridge project over the Hudson River does! The New York State Thruway Authority is replacing the Governor Malcolm Wilson Tappan Zee Bridge that crosses the river, connecting Westchester and Rockland counties. The new 3.1-mile state-of-the-art, twin-span structure, now called the Governor Mario M. Cuomo Bridge, will be one of the largest single design-build contracts for a transportation project in the United States. Located less than 20 miles north of New York City, the span crosses one of the widest parts of the Hudson and is the largest bridge in New York State history. The Tappan Zee Bridge opened to traffic back in 1955 and, until its retirement in 2017, was a vital artery for residents, commuters, travelers and commercial traffic. The bridge carried a whopping 140,000 vehicles per day in 2016, far more than it was ever designed to accommodate. Heavy traffic, narrow lanes and the lack of emergency shoulders were creating potentially unsafe driving conditions. As a result, the bridge had twice the average accident rate per mile as the rest of the 570-mile Thruway

system. Hundreds of millions of dollars were spent to maintain the structure in recent years, and the cost of maintaining it for the foreseeable future rivaled the cost of a new bridge, with no improvements to current traffic conditions. The New York State Thruway Authority retired the bridge on October 6, 2017, after nearly 62 years of service.
The design-builder, Tappan Zee Constructors (TZC), hired CSDA member Atlantic Concrete Cutting Inc. (ACC) for one massive project and tasked them with completing a saw cutting job for demolition of the old bridge. This included deck sawing for removal of precast panels, saw cutting of the concrete and steel grid-deck, substructure wire sawing throughout the length of the bridge, miscellaneous core drilling of rigging holes and plunge cutting of the bridge sidewalks and dams. Concrete cutting offered ideal solutions for this particular project for many reasons. Saw cutting of the precast panel grout joints and plunge cuts ensured an easier removal process for each crane pick. Ten-degree bevel cutting of the grid deck with 36-inch and 42-inch Diamond Products (DP) blades allowed TZC to remove large center portions of each under-deck truss span, reducing each span’s weight. This allowed for entire spans to be picked and removed using TZC’s shear leg crane.

Ten-degree bevel cutting in the under-deck truss portions of the bridge (approximately 1/3 of the 3.1-mile structure) allowed the pieces to be left wedged in place temporarily, which eliminated the need to strap or anchor the pieces. This also eliminated cutting in constant coordination with the rigging and removal operation, which would have otherwise been very timeconsuming considering the length of the bridge. Wire sawing was used to downsize large substructure columns and pier caps, allowing them to be placed onto barges for removal. This reduced some of the environmental concerns associated with conventionally demolishing these larger concrete elements. Other methods of total conventional demolition were considered C O N C R ET E O PEN I N G S | 7

prior to the job, as well as implosion. However, these were quickly ruled out due to proximity to the new bridge, time constraints and the heavy marine traffic under the bridges. After the initial bid process, the design of the cutting operations went through several iterations, ultimately resulting in a final scope with the decision to saw the entirety of the longitudinal cuts in the grid deck at a 10-degree bevel. During the summer of 2017, ACC worked closely with DP to develop a custom slab saw that would work ideally for the tasks at hand. After the closing of the Tappan Zee Bridge on October 6, 2017, ACC mobilized to the site to begin deck sawing operations. The Work on the new twin-span bridge continues as the old bridge’s main span is dismantled. first item of work completed was the cutting of grout joints between precast deck panels that were installed before Christmas.

Four of these piers had to be sawcut and removed during winter months to facilitate commencement of the final construction of the new eastbound bridge, slated to begin in March 2018. Atlantic demobilized in late January 2018 and returned two months later to begin wire sawing the remainder of the hollow column cuts and complete bevel-cutting of the remaining two truss spans. Core drilling of the associated rigging holes are slated for completion in September 2018. The job didn’t come without its fair share of challenges, some of which were global, and others more specific to individual tasks. Gaining access to

the job site was a constant hurdle due to a variety of factors, including alignment with major highway I-87/287 and each end of the new eastbound span conflicting with the footprint of the old bridge. To allow new construction to continue in these conflicting areas, both ends of the old bridge were essentially lopped off early in the demolition process. All access for the remainder of the job was via marine methods only. Crews had to park on shore and take a boat to their work area. Wire sawing operations were conducted mostly from barges, while deck cutting operations were accessed via temporary stair towers. Similarly, the delivery of equipment and materials had to be coordinated between several parties and modes of transportation. For example; delivery of just four bridge deck blades for the slab sawing operations would require shipping to a marine yard, transfer of the blades onto a tug boat and/ or barge, then delivered to a nearby crane and finally picked up by crane and placed on the deck. Additional training and procedures were put in place for the marine operations too. TZC engineers carefully designed a bevel-cut deck process to ensure that
in addition to the deck panels not falling through after being cut free, the panels would sustain working loads to facilitate their removal. The constant change in weather conditions in the Hudson River Valley also presented challenges, especially with work continuing through the winter months. ACC (and TZC crews) had to wrestle with high winds, rough water conditions (including ice flows) and freezing water pumps and saw components. With more than 43,000 linear feet, the longitudinal bevel cutting operation was the largest deck cutting portion of the job. TZC proposed a 10-degree option with the use of Diamond Products’ existing Rider Saw line, which has the capability of variable tilt of the blade shaft (up to 10 degrees). While the DP Rider Saw line was designed to cut at 10 degrees, ACC needed a custom saw that could cut exactly 10 degrees while also sustaining repeated use for this application. The DP Rider Saw was capable of this, but wasn’t available with a Tier 4 engine as required by the project. The solution was to modify an existing Tier 4 saw. DP and ACC developed an innovative modification to the DP CC7574 slab saw that allowed the entire saw to tilt 10 degrees.

The new bridge’s aesthetic lighting illuminates the structure’s piers and towers.
The design allowed the saws to essentially function normally while also cutting at the desired angle. This addressed most importantly the issue of blade geometry, as the blade is raised and lowered into the cut at this angle. Once the saws were designed, fabricated and on the bridge deck to start work, ACC had to also address the challenges of blade wear and failure. In addition, ACC had to come up with a shimming and wedging system to keep pieces from constantly pinching the blades. Though ACC had many challenges and hurdles, all bevel cutting operations were finished on time and under budget, achieving between 1,100 and 1,700 linear feet daily with two bevel saws running. In total, the job included 46,000 linear feet of 10-degree bevel cut grid deck and four-inch thick concrete over 3.5-inch steel T-grid. Also, 13,000 linear feet of transverse grid deck cutting was performed. There were 400 plunges through steel, concrete sidewalk and bridge dams. Wire sawing of approximately 8,000 square feet of cuts in large hollow columns was completed with an additional several thousand square feet of wire sawing performed throughout the duration of the job. Multiple ACC crews worked per week to complete all scope items, working five 10-hour shifts on a regular basis, as well as many nights and weekends as required by TZC’s strict demolition schedule. ACC’s scope was finished on time and within budget thanks to the hard work and ingenuity of the entire ACC staff. The DP engineering team’s innovative design for the bevel saw played a key role in the success of this project too. ACC’s talented field operators and dedication to quality helped them

ACC Project Manager Wes Jones explained, “I grew up driving up to visit family in New England and it is hard to imagine that a structure that seemed to take forever to cross in a car is now substantially demolished in less than a year.” He continued, “Atlantic Concrete Cutting has taken on a lot of large projects in the area over the years, but I think all of our guys saw this as a unique, challenging and high-profile project that we will be proud to talk about for years to come.” REVIEW AND COMMENT ON THIS ARTICLE AT: WWW.CONCRETEOPENINGS.COM

Cutting steel from test cylinder with a Diamond Products Core Cut C16 and fiber wheel.
PAVING THE WAY FOR AN “UNCRACKABLE CONCRETE” I n December 2016, the University of Tennessee’s (UT) Department of Civil and Environmental Engineering approached CSDA member Cuts Inc. with an unusual request. In an effort to produce a more crack-resistant concrete they began a project called “The Effect of Alkali-Silica Reaction on the Fracture Properties of Concrete.” This test began with UT creating concrete cylinders encased in 9/16-inch thick steel casings 26 inches in diameter and 8-16 inches tall. These specimens were made with
a highly reactive coarse aggregate which was chosen in order to increase the rate and amount of concrete cracking. UT needed a skilled contractor to cut test blocks of very specific shapes, sizes and orientations in order to investigate the effects that the cracking would have on the concrete strength.

The University had specific ideas for the multiple shapes and angles desired for the test blocks but had no way to pull them out of the concrete cylinders themselves. Prior to being awarded this job, Cuts Inc. was asked to come to the university to discuss the job and go over details and drawings with engineers. Cuts Inc. has extensive experience fabricating custom sawing and drilling equipment as needed to perform challenging tasks, however, President Matthew Hephner admitted, “As I sat in the meeting with UT being asked how we would accomplish these unusual cuts, to be honest, I didn’t know exactly…but I did have complete trust that our team could and would figure it out so we confidently said, ‘Yes we can do it.’” Cuts Inc. was given cylinders to cut on three separate days spread out over a 19-month period. On the days they were provided the test cylinders, they cut six blocks of various shapes at different angles out of each cylinder for a total of 54 test Exposed aggregate and surrounding concrete being examined by UT.
Examining the exposed concrete after four cuts had been made.
blocks. This required some trusty saws, blades, bearings and even a custom tool that Cuts Inc. had to design specially for this paticular job. A custom-built table was needed before cutting could take place. The operators needed something that allowed infinite adjustment in both latitudinal and longitudinal directions, could be rotated and be locked in each position. Matthew Hephner designed this precision shiftable rotating table. He and his team built it in the Cuts Inc. fabricating shop using Acme threaded rods for the positioning and an 18-inch diameter slewing bearing able to support the 600-pound cylinders. The entire table can be adjusted and moved from left to right, has a rotating turn table in the center and features a locking handle in the front. All of the components were crucial to get accurate results. The use of a fork truck was necessary to lift these cylinders onto the newly crafted table. The first six blocks

that were cut were simply to verify they could meet the required dimensions within the 1/16-inch tolerances. After this was successfully achieved, the operators then cut and removed the steel bands from the cylinder with Diamond Products Core Cut C16 saws and fiber wheels. The next step involved postioning a cylinder and then strapping it to the table with ratchet straps. With the Pentruder 8-20HF wall saw mounted overhead, the first test block cut was made. A 42-inch diameter Diamond Products blade was used for each one of the cuts. Between nine and 11 cuts were made on each cylinder, with each cut being made in a specific order dictated by UT until six 200mm rectangles were created from each cylinder. Finally, Cuts Inc. used a Diamond Products Core Cut 811 block saw with a 24-inch blade to cut the additional recesses and slots in each block to create the various desired shapes. This unique job truly needed the precision and accuracy that only diamond tools can offer. Diamond sawing was the sole option for making such exact cuts. These tools and this process were repeated and used on all test cylinders to produce all requested test blocks for UT’s project. “We have all been pleased with the quality of cutting. In fact, the dimensional variation of cut specimens is smaller than the variation of the specimens that we cast ourselves in custom molds,” said Graduate Research Assistant Nolan Hayes from the Department of Civil and Environmental Engineering at UT.

the Atlantic Ocean on the other. Where there is water, there are bridges, and where there is salt water, there is corrosion. The Halls River Bridge in Homosassa, FL was in major need of a replacement after becoming the latest victim of salt water corrosion. In fact, most bridges built over salt water will ultimately require future repairs or replacement due to the corrosion it causes to steel rebar over time.
Carbon fiber reinforced polymer or carbon fiber reinforced plastic (CFRP or CRP), is an
The cut deck stacked and ready to be hauled off to a local recycling plant.
The Halls River Bridge job was awarded to general contractor, Astaldi Construction Corp., who had an innovative project in mind to fight back against the corroding sea. Carbon fiber reinforced polymer, or CFRP, is a non-metallic, non-corroding material that is quickly becoming the “go to� alternative to steel rebar, especially with salt water structures. Before Astaldi could get started on their special project, they needed to contract an expert concrete cutter to assist them. CSDA member Accu-Cut Concrete Services, Inc. was an obvious choice for their extensive expertise and experience around the greater Tampa Bay area. This project included the removal of the old bridge and the building of a new, wider bridge at a higher elevation. The new bridge was to be constructed of concrete with CFRP in place of steel rebar and used throughout the entire structure. Saw cutting the old bridge for removal was to be done in two phases. Phase one would include demolishing half of the old bridge and leaving the other half open to traffic, while the first half of the new bridge was constructed. Then, phase two would involve demolishing the second half of the old bridge and completing the new one. Concrete sawing using diamond tools was the perfect solution for this job, as it left the second half of the old structure undamaged during phase one. This was crucial so that traffic could continue to cross the Halls River during the duration of the project.

extremely strong and light fiber-reinforced plastic material which contains carbon fibers. CFRP can be expensive to produce, but is commonly used wherever high strength-to-weight ratio and rigidity are required, such as aerospace, automotive, civil engineering and an increasing number of other applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester or nylon, are sometimes used to bond too. The composite may contain ultra-highmolecular-weight polyethylene (UHMWPE) and glass fibers in addition to the carbon fibers. The properties of the final CFRP product can also be affected by the type of additives introduced to the binding matrix. The most frequently used additive is silica, but other additives such as rubber can also be used.
river and has a very active waterway, with daily boat traffic. Concrete cutting also proved to be the ideal choice for a very environmentally sensitive area. Other demolition methods such as jackhammering would have created more concrete debris, posing a threat to local marine life. With Homosassa Springs Wildlife State Park just half a mile down the road, state protected land and wildlife was at the forefront of concern. Accu-Cut began this unique project by core drilling approximately 96 temporary barrier wall bolt holes down the center of the old bridge to define the phase separation.

the phase one portion of the bridge. A combination of Diamond Products Weka DK52 and DK42 Core Drills and a custom-built core drill machine designed by Accu-Cut were used when drilling all holes for the project. Accu-Cut started the slab sawing portion of the job by cutting 180 linear feet of approach slabs, followed by about 720 linear feet of deep bridge deck sawing at a depth of 10.5 inches, using two Diamond Products slab saws; CC6566 and CC3765 models. The deck was removed via crane to allow Accu-Cut access to then perform 13 wire saw cuts through the pile caps

This state park is located within the Homosassa Wildlife Management Area which consists of more than 5,000 acres in southwest Citrus County between the Homosassa and Chassahowitzka Rivers. The area is a management unit of the Withlacoochee State Forest and consists of wetlands, planted pines and improved pastures.

Finally, 52 18-inch pile cuts were wire sawed to complete phase one demolition. Standard PPE associated with bridge work was provided for all operators and included fall protection and personal flotation devices. Although this job may be smaller in comparison to other bridge jobs, there are various details and challenges that make it a high-profile project that has captured the attention of professionals nationwide. The environmental aspect of the job alone is captivating. The bridge lies within the Homosassa Wildlife Management Area which is home to manatees and other various types of wildlife. For the duration of any job within this area, it is required that personnel are posted solely to watch and alert workers of any manatees in the immediate area. If a manatee is spotted, projects are paused until the animals swim a safe distance away from construction and demolition. There was a lengthy delay during phase one due to an osprey nest built on top of a crane over a weekend. A permit was required to remove the nest and it took a full month to acquire permission to safely relocate it. Slurry and debris were strictly prohibited from being dumped into the water under the bridge to help protect the fragile ecosystem. Again, even though this is a smaller bridge, due to the new composite design with the CFRP, this has become a highprofile project with many interested parties from across the U.S. paying close attention to the installation and construction of this new steel rebar alternative.
Snorkelers can view manatees in natural springs all over the state of Florida.

Specifiers Industry Bits c o n t i n u eCorner d
Specifiers & CSDA Contractors Make a Perfect Team By George Seegebrecht Specifiers Corner was created to connect CSDA’s network of concrete cutting professionals with global specifiers in the industry. The goal is to continue CSDA’s efforts to promote the sawing and drilling industry by highlighting the benefits of working with contractors who use diamond tools. The architecture and engineering industries can benefit greatly with diamond sawing and drilling as a resource, and this column aims to showcase just that!
A
s a friend of Concrete Sawing & Drilling Association (CSDA) for well over 20 years, it is a pleasure to tell you how CSDA has helped me with project work through the years. It all started with Pat O’Brien, Executive Director of CSDA. In fact, I grew to know Pat for about 10 years before meeting face to face. For 25 years I worked for the Portland Cement Association (PCA) and its consulting subsidiary, Construction Technology Laboratories (CTLGroup). This work required field trips to evaluate concrete problems in different parts of the country. Concrete problems varied widely from low strength, discoloration, cracking, scaling and other symptoms of premature distress or loss of durability. Coring for sampling, examination and testing could be considered routine but there were other projects like examination of fire damaged concrete structures, waste water treatment plants, spillways and sampling the lining of smoke stacks or pedestal water tanks. So, “routine’’ is a relative description that varies for everyone. These investigations commonly required obtaining samples of various concrete structures. Our lab had excellent people and equipment, but some jobs didn’t economically justify traveling with a crew and equipment to cut a small number of samples for part of the evaluation. Conversely, sometimes the size or complexity were beyond our capability.
24 | SEPTEMBER.18
We typically searched for test labs or coring companies near project locations who could secure sawn or cored concrete samples intended for examination and testing in our laboratories. This worked fine most of the time but then I found CSDA and I began to develop my relationship with Pat O’Brien. CSDA referred me to member companies that were equipped, skilled and experienced to handle difficult or unique jobs. They did a safe and efficient job of obtaining samples in difficult access conditions. As time went on, I would call CSDA and request if they had members in Anchorage, Alaska, Port St. Lucie, Florida or Portland, Oregon. They were able to provide me with concrete cutting contractors throughout the county and were frequently able to accommodate different parameters. Initially Pat would recommend the members that were reasonably close to my next project. After a few years, the CSDA developed a Member Directory, listing members by state. I bet Pat had the Directory printed to reduce the number of times I called and bothered him! This helped because other engineers in our office would stop by and ask for my CSDA directory or coring company suggestions when they traveled to different cities. Today it’s even easier with member contacts available online. I frequently refer colleagues and clients to the CSDA website which has a search request function. Let me share a few projects with CSDA members that were made easier due to their skill, availability and experience. EAST COAST VIADUCT An evaluation of a 100-year old viaduct on the east coast required core samples to be included from the underside of the in-service viaduct. Coring upside down is much more challenging and it’s typically only experienced core drillers who know how to properly perform this type of cutting safely and correctly. First, operators need to safely and securely bolt their core machine to the ceiling to avoid it detaching and injuring operators.
Additionally, operators must be careful of cooling water draining onto the machine from the core hole. It’s best to use a hydraulic rig, as they’re specifically designed to protect against electric shock when water is involved. If this option isn’t possible, operators should be extremely careful and use things like water collection rings, water vacuums and plastic wrapping materials that don’t cover vent holes. The contractor for the viaduct job performed their work using some of these techniques and kept the cutting safe and efficient, while also reducing our estimated time in the field. This allowed more time for surveying the overall structure in the field for our report. Cores were extracted in our requested location, without damage due to coring, producing samples that were representative of the condition of this approximately 100-year-old concrete. RCC DURABILITY STUDY A study was conducted by PCA to evaluate the durability of newly placed roller compacted concrete (RCC) in various locations around the U.S. that included intermodal yards, military tank hardstands on the west coast, refineries, sea ports and airports. This project called for straightforward coring, but we needed about 30 six-inch diameter cores from each location. Additionally, all core holes needed to be patched so the owner was not left with holes all over his pavement that were subjected to severe and abrasive service conditions. The selected coring contractor had all the tools in one vehicle along with replacement parts in case of a breakdown. The coring contractor even had a concrete mixing drum inside their UPS-type vehicle with batching materials to repair each of the core holes after they were drilled and photographed. Cores were typically taken in one day and included cutting, cataloging, packaging for shipment and repairing of all core holes. CORE CONDITIONING STUDY A joint study by PCA and the National Ready Mixed Concrete Association (NRMCA) was conducted to compare the effects of various curing methods on strength of cores and cast cylinders. When testing samples taken from concrete, the standard to follow is ASTM C 42Standard Test Method for Obtaining and Testing

Drilled Cores and Sawed Beams of Concrete. Questions were raised in the industry about the effect of moisture conditioning of cut cores or beams in terms of their indicated strengths.

CSDA members cut concrete as their main business line in most cases. They have worked on difficult projects before. Their experience is invaluable. They know the safety issues and most potential problems that could be encountered. If they can’t do the job, they will most likely know who can and how a previous job turned out.

curing conditions. Slabs were cast for the study and then cored to compare eight-inch long cores that were moist cured, air dried and placed in plastic bags. The core values were then compared to results obtained by standard cast cylinders. Cores had to be taken in a timely manner for an accurate comparison. The CSDA member company understood what needed to be accomplished and helped make it happen. FIRE DAMAGED STRUCTURES Concrete exposed to fire does better than most materials. Finding out the extent of damage requires examination. Visually a structure may look severely damaged but obtaining samples can provide information on the extent and severity of fire related damage. More significant damage may occur during firefighting efforts, as cold water impinges on the elevated temperature concrete.

Finally, for engineers and architects doing similar work where concrete samples must be obtained, penetrations must be created through concrete structures, or large sections of concrete are required to be removed as part of repairs or structure modifications, here are a few reasons to explore CSDA as a resource to help with such projects no matter what the size or complexity. Most CSDA members do more than just coring and their individual capabilities are presented in the CSDA directory. Services include: coring of various size core diameters, flat sawing of both flatwork and walls, diamond-wire rope cutting of large or unique shapes, demolition and others. On that note, just talking to some of the experienced veteran members like Tim Beckman of Cutting Edge Services in Ohio has been so helpful and educational in the
CSDA provides its members with certification and training programs to help provide a consistent level of expertise and professionalism on all projects. This is a reason I am comfortable starting my search with an association member. CSDA members are up to date on equipment use, safety procedures, core hole patching, rebar and utility detection and so much more. As an engineer who has used the services of many CSDA members all over the United States and Canada, I recommend a visit to the CSDA website at www.csda.org to become familiar with the resources of the association. If you are planning on attending the World of Concrete in Las Vegas, stop by the CSDA booth in the Central Hall and speak face to face with CSDA staff about the training and resources they provide. It could make your next project easier, safer and more cost effective. In closing, many years ago I was manning a booth at a convention and during some down time looked through the booth directory and was excited to notice that CSDA was exhibiting right down our aisle. I walked over and saw the name tag of Pat O’Brien. I stuck out my hand to say, “We’ve never met but I have known you for at least 10 years.” We’ve been friends ever since.

IACDS President’s Insight
I
have to say I returned from the IACDS Convention in Tokyo more enthused and more excited about our industry than I have been in a very long time. First of all, what a beautiful country! Everyone was so friendly and welcoming to everyone from associations all around the world. The convention was inspirational and brought home to me how important it is to network with one another across the globe. There were presentations on two amazing technical case studies. One was on the Ruskin Dam seismic retro fit project in Canada and the other on an underground Tokyo station. Along with these fascinating case studies were other useful topics including employing millennials and dismantling technologies in nuclear power plants. We had an incredible visit to Daiichi-Cutter—the largest concrete cutting company in the world—and they gave us an insight into their new slurry removal machinery that can remove thousands of litres of material at any given time. In one of the meetings, we had 18 different nationalities represented, which was incredible and that diversity of people, cultures and different ways of working just brings a real freshness to the convention. Overall, there were seven national associations represented including CSDA (USA), DSA (UK), BFB (Sweden), JCSDA (Japan), AEDED (Spain), SNED (France), FBS (Germany) and there were over 100 delegates in attendance. We had eight fantastic speakers on a range of topics and we’d like to thank Joel Vinsant, Erin O’Brien, Cota Fujio, Brian Wnuck, Jun Ozawa, Martin Braun, Michael Findeis and Reiner Schulze for their contributions to the event. We must also thank the sponsor, Tyrolit,

who made possible the staging of such a wonderful convention and our five exhibitors: Shibuya, Pentruder, Hakken, Hilti and Cretebeater. You may not know that the IACDS has a figure of honorary member and, up until this convention, only JULIE WHITE one person had received IACDS President this honor and that was Otto Alte-Teigeler, the IACDS founding president. I was thrilled to have the honor of investing a new IACDS member this year to Mr. Norikazu Shibuya. He has made great contributions to the organization and the industry through the years. He is an absolute inspiration to many and I was proud to recognize him in this way. The next convention is in Bauma, Munich (April 8-14, 2019). I urge you to attend. It’s such a fabulous networking and learning experience for everyone who participates. We are also looking towards the Diamond Awards on April 11, 2019—during Bauma—for all contractors to enter and for the first time will be recognizing our excellent and innovative supply chain—with an award for best product. For more information go to www.iacds.org or contact your national association. And, as I always say, please feel free to get in touch with me on any matters that you want IACDS to look at.

Your Salad is Hiding a Dirty Secret By Erin O’Brien
W
hat if I told you a cheeseburger was healthier than a wedge salad? Sounds crazy, right? Salads are supposed to be healthy! Yes, they are, but not the way most Americans eat them. Many salad options today are anything but healthy. Remember the recent E. Coli outbreak in romaine lettuce? And don’t get me started on salads served in most restaurants —covered in sugar-laden salad dressing, sugar-encased nuts and crunchy fried tortilla strips. Here’s the deal—salads can, and should, be healthy! The problem is, most salads start with the wrong foundation—the greens. First, we’re going to break down the different types of greens that serve as the base for your salad and where you may be going wrong. There are a few options for your salad base – lettuce, cabbage and greens. Lettuce is an annual plant of the daisy family, and there are 16 different varieties (we’ll discuss these in a bit). Kale belongs to the cabbage family and arugula belongs to the greens family, which includes collard and mustard greens. Let’s first discuss the benefits of all these types of lettuce/greens. Vitamins – kale and lettuce are full of them! Kale and red leaf lettuce provide up to 42 percent of your daily value for Vitamin A (an antioxidant that aids vision and immune functions), while romaine offers up to 82 percent. If you cook your kale, the Vitamin A content rises to almost twice your daily requirement. Vitamin C is found in high quantities in kale as well, offering anywhere from 30 to 150 percent of your daily value. Vitamin C is another antioxidant that fights off cell damage and builds collagen, a protein that serves as a building block for all tissues. Finally, kale and lettuce offer up to 140 percent of your daily value for Vitamin K, which supports healthy bones and plays a vital role in the blood clotting process. Minerals – calcium, magnesium and manganese are all found in smaller quantities in kale and lettuce, providing about 15 to 20 percent of your daily value. These minerals support the health of your bones and teeth, as well as assisting in enzyme functions.
30 | SEPTEMBER.18
Calories – all varieties of lettuce, kale and greens are very low in calories, as well as fat, protein, carbohydrates and fiber. Including lettuce, cabbage and greens in your diet will ensure you are providing your body with vital nutrients that contain an abundance of antioxidants and carotenoids, which protect cells and may have anti-cancer properties. They are also very low in calories, carbohydrates, sodium and cholesterol, all things we should try to limit. We’ve established eating lettuce and other greens is good for you, but what types are best? Below, we’ll rank the options. This may even introduce you to some new greens you didn’t know existed! THE TOP FIVE Microgreens The jackpot of leafy greens, consisting of the underdeveloped green leaves of vegetables such as arugula, broccoli and kale. Since they are harvested young, they retain more of their vital nutrients, and will often have less exposure to chemicals and pesticides.
Kale A member of the cabbage family, kale contains lutein, an antioxidant that improves your eyesight. It contains many vitamins, as mentioned above, and other nutrients that slow the growth of cancer cells. It has everything! It is somewhat bitter in flavor, which can be helped by sautéing or steaming. Spinach Contains high levels of folate, a B vitamin that promotes heart health and can also slow the growth of some cancer cells, and potassium, which keeps blood pressure in check. Spinach stands alone well in salads or on sandwiches, but also sautés well. Living Lettuce Sold with its roots still attached, which reportedly helps preserve the nutrients in the leaves by providing a constant source of moisture. This type of lettuce can last for two weeks in the fridge. Common varieties are Bibb/ Boston, leaf and romaine. Collard/Mustard Greens This southern staple offers a higher amount of fiber than other types of lettuce and greens,
and is also high in beta carotene, which strengthens eyes and bones. Heartier than other options, these need to be cooked or simmered longer. MIDDLE OF THE PACK Swiss Chard Similar in texture to kale and collard/ mustard greens, this dark, leafy variety with colorful stems is high in nutrients and sautés well. Arugula/Rocket Popular in Mediterranean cuisine, this variety of leafy greens grows on stems and has a slightly peppery, bitter taste. Watercress Aquatically grown (grown in water), watercress has long, hollow stems and round leaves. Similar in flavor to arugula and is good in salads and stir-fry. Red/Green/Oak Leaf A common variety in supermarkets, leaf lettuce has curly leaves, crisp stems and is sweet and mild. Good in salads or on sandwiches. “Spring Mix” Technically not a type of lettuce, cabbage or greens, Spring Mix is a marketing term used to described bagged or pre-assembled varieties of lettuce and usually includes a mixture of spinach, arugula, romaine, radicchio and baby kale. Nutritional content varies depending on what’s included. LOWEST ON THE NUTRITION TOTEM POLE Bibb/Boston Delicate with pale green, cup-shaped leaves. Mild and sweet. Often grown hydroponically (using water only, no soil) and
are good for lettuce cups and wraps. Less nutrient content than other lettuce varieties. Radicchio Italian variety of lettuce, dark red, firm leaves with white stems. Tends to be bitter and stands up well to grilling. Romaine Popular with Caesar salads. Long, firm green leaves with white stems. Often sold bagged with just the sweeter, interior leaves (hearts of romaine). Nutrients are found in the green leaves, fewer in the white stems. Bitter, but grilling brings out a sweeter flavor. Frisee/Curly Endive Long, slender feathery leaves. Slightly bitter and has little nutritional content. Iceberg Popular in salads, due to its firmness and low cost, but little taste or nutritional value. Mostly water. Other less popular varieties of lettuce include: endive, Mache, mizuna/Japanese mustard greens and escarole. All of these can be used in salads and soups but provide little nutritional value and are less likely to be found in your local supermarket. Still, if you can find them, they can provide variety in your leafy green diet. Farmers markets and health food stores often carry many of these varieties. You’ll notice that iceberg comes in dead last on this list, which brings us back to the beginning, and my least favorite salad—the famous, and extremely popular Wedge. A Wedge salad is typically a chunk of iceberg lettuce covered in blue cheese or ranch dressing, topped with crumbled bleu cheese and bacon bits. Now don’t get me wrong, it tastes great—creamy dressing, cheese and bacon! But this hardly counts as a salad. There
is no nutritional value outside of some protein from the cheese and bacon. It does have lots of added calories and sugar from the dressing, and the lettuce is just water and a tiny bit of fiber. So, while you may think you’re eating healthy because you ordered a salad, think again. The same is true for other restaurant salads that use iceberg and romaine as the base, and add on lots of sugary dressings, crunchy toppings like croutons and tortilla strips (hello bad carbs) and sugar-coated nuts and dried fruit (which, if fresh, would otherwise be a fantastic addition!). Bottom line—leafy greens, lettuce and cabbage can be healthy and good for you, and everyone should include them in their daily diets. But beware of lettuce imposters like iceberg and romaine and watch what you add to your salad. For example—one of the worst salads you can order at a restaurant sounds pretty healthy. California Pizza Kitchen’s Waldorf Grilled Chicken Salad with Fat-Free dressing weighs in at a whopping 1,340 calories, 87 grams of fat (and that’s with the fat-free dressing!), 2,090 mg of sodium and a sickening 66 grams of sugar. That’s more sugar than two Twix bars and accounts for more than two days of your daily sugar intake, as well as more than half of the recommended daily calories for an average adult. The best type of salad is the one you make yourself, so you can control what you put on it. If possible, buy your greens from a farmers market or organically, so you can avoid pesticides, chemicals and potential disease outbreaks common in many commercially grown lettuce varieties (especially romaine and iceberg). The internet is full of delicious salads and other recipes that include kale, greens, spinach and more. For anyone interested, I have a few standbys that have never let me down, and I am happy to share.

Concrete Cutting Contractor Tackles Savage Hurricane Aftermath Satellite view of Hurricane Harvey making landfall in Texas.
Cut footer being removed via crane.
32 | SEPTEMBER.18
W
ho could forget the absolute destruction Hurricane Harvey caused when it hit Texas on August 25, 2017? The massive storm brought with it not only damaging hurricane-force winds of up to 130 mph, but an incredible 51 inches of rainfall, all in just a short few days. With such a heavy amount of rainfall, all area rivers, ditches and dams overflowed their banks, causing mass flooding and devastation the area had never experienced before. Waterways like the idyllic San Jacinto River, which normally could be fished with waders, became raging torrents, carrying with them trees and debris as the water raced down to the Gulf of Mexico.
As all storms eventually do, Harvey dissipated and the water levels began to recede. At this point it was crucial that the infrastructure of bridges in the area be promptly inspected for any potential damage caused by the flooding. One bridge, the Highway 59/Interstate 69 Bridge in Humble, Texas, was of immediate concern because of the tons of debris that had collected on and around its piers, columns and piles. After a thorough inspection of the structure, it was determined that the increased water flow and rate of speed had scoured the river bottom from around the piles. This was a river that used to be just 15-20 feet deep under the bridge, that had now doubled to 30-40 feet. The bridge’s piles, that used to be well embedded into the river bottom, now had less than 50 percent embedment. Consequently, the bridge was now highly unstable and could have fatal consequences if not tended to right away. Since the condition of the bridge posed serious hazards, repair became a top priority. Quotes were tendered for an emergency renovation, which would involve selectively removing the center three spans of the bridge that were located directly over the river channel. As a major highway route leading in and out of Houston, this project was deemed extremely timesensitive by the Texas Department of Transportation who allotted only 113 days for the bridge to be closed to traffic. When general contractor Webber LLC was awarded the project, they knew concrete cutting would be the ideal method of selective demolition due to its ability to safely remove specific portions of the bridge without damaging others. Now all they needed was to contract a concrete cutting company for the demolition portion of the project with a track record of producing quality work within a narrow timeline. That’s when they called CSDA member Aggregate Technologies, Inc.. Aggregate has highly experienced management, staff and operators, all backed by a wide variety of equipment and technology. For these reasons Aggregate was the perfect W WW. C O N C RE TE OPE N IN GS.COM

contractor for the job! Webber tasked Aggregate with taking down the required three spans of the bridge from the top deck and performing underwater wire cutting of the piles as well. Prior to making their first cut, Aggregate had to consider safety, efficiency and speed while determining which methods and procedures they’d use to accomplish the tasks of this important job. Before Aggregate could begin their portion of the work, Webber had to tackle the bridge deck. Webber started demolition by hammering the bridge deck into rubble with a hoe ram attached to an excavator. The rubble was dropped onto a barge tethered in the river underneath the bridge and then collected and removed with the use of a skid steer loader. Next, the main beams were lifted by crane out of place and removed from the site. This left three sets of bents, caps, columns, footers and piles for Aggregate to cut and remove, with each bent consisting of three separate structures. The original bridge had been widened twice, once on the outside and once on the inside. A different design was used on each widening phase, leaving Aggregate working on a variety of different piles, caps and piers. Meticulous attention to detail and regularly adjusting equipment during the duration of this project were determining factors in completing the job on time. Aggregate used Diamond Products wire saws with wire lengths between 35 and 60 feet to cut the caps and piers first. Then, they continued wire cutting the piles that were underwater, to ready the footers to be lifted off and removed by 34 | SEPTEMBER.18

crane. Finally, Aggregate operators used Prime Marine Services Model 24 hydraulic shears to cut the piles off at the mudline. Once the first set of piers was removed, new drill shafts were installed and the drilling and demolition continued simultaneously until all the old structures were removed. The job certainly wasn’t without its challenges though. The changing

tides required operators to make constant alterations to just about everything on the job site. Tools and equipment had to be adjusted regularly. Additionally, barges and cranes had to be simultaneously maneuvered, within very tight spaces, so each operator could continue their respective operations safely. Once Aggregate completed all their cutting tasks, it was time for Webber LLC to step in again. Webber systematically rebuilt the bridge like a large LEGO set: drilled shafts, placed caps, beams, deck and barrier walls, then voila! The new bridge was ready for traffic again. Take that, Hurricane Harvey! The Texas Department of Transportation had allowed for liquidated damages should the project go past the allotted time. They also offered a performance bonus for every day under the 113-day time limit, up to a maximum of 10 days. Not only was the bridge completed and reopened to traffic on time, but the full 10-day performance bonus was presented to Aggregate for their efforts. Great job, guys! Project manager, Greg Major, praised the project saying, “This job went very well for us despite the challenges of working within close proximity to Webber LLC and our respective work schedules. I believe the experience and professionalism of our operators was a key factor in this project meeting its goals and expectations.�

perating a forklift is no picnic. Even in the most optimal conditions, these vehicles are complex to drive and difficult to maneuver. In busy warehouses and on job sites, it can seem like a painstaking operation. There are new perils that greet drivers on a daily basis. These dangers are amplified by many mistakes that often could have been easily avoided, one of which is failing to take notice of blind spots. Are your drivers finding themselves beleaguered with accidents? Are there new incidents emerging on a continual basis? There are some steps you can take to mitigate risk. Locating and strategizing on how to handle the most dangerous blind spots in any warehouse will be sure to reduce these events. Here is how: 1. CORNERS AND DOORWAYS Corners and doorways are two of the sure-fire areas where accidents are bound to happen. This is because foot traffic is most prevalent by a doorway, and people working in corners can be difficult to see. It is essential that any forklift operator slows down as they approach a doorway to check for oncoming pedestrians. Additionally, corners should be approached slowly to ensure that all aspects of the area are accounted for. In doing so, some of the most common accidents can be easily avoided. 2. ALERT OTHER DRIVERS When it comes to vehicle accidents, a lack of communication is often the culprit. As multiple operators work in one area, it is imperative to bolster communication through a wide range of initiatives. Whether it be a gentle sound of the horn, flashing of lights

or hand signals, these are all steps that forklift drivers can take to avoid colliding with another material handling appliance. Many car accidents are caused in similar regard, often from the driver’s failing to convey a right of way or intent to move. Establishing a protocol that mirrors this phenomenon is another way to create an approach that limits incidents in any warehouse.
3. DARK AREAS Dark areas are those spots of the warehouse that are dimly lit or cast many shadows. Whether it’s an out bulb, stacked inventory blocking lights or just a lack of windows, these environs are especially dangerous if personnel find themselves gathering raw materials from these settings. In these conditions, it is essential to get another set of eyes. Operators should recognize when visibility is blocked and acquire a spotter to act as an additional set of eyes. In doing so, the forklift operator can also locate pedestrians and properly alert them of their presence in the area. This is yet another way a dangerous blind area in a warehouse can be tackled and safe operations can be executed seamlessly. It is also crucial to make sure all mirrors provide a full landscape view of the production floor.

The Business of Business
The Great Generational Shift: How Employers Can Prepare in 2018 By Bruce Tulgan
THE NUMBERS PROBLEM: WORKFORCE 2018 AND PROJECTIONS FOR 2020
I
n just the last year alone, millions of First Wave Boomers and pre-Boomers have left the North American workforce, while millions of Second Wave Millennials have joined. The long-dominant Boomers are on the wane, while the Second Wave Millennials are on the rise. The oldest of the First Wave Boomers are now in their 70s and every single day, in North America alone, another ten thousand First Wave Boomers turn 70. The trends (percentage-wise) are very similar throughout Europe and in Japan. By 2020, First Wave Boomers will be well under six percent of the workforce, and those who do remain in the workforce will continue trending heavily toward reinventing retirement and late-career-pre-retirement: working less than full-time, often partially telecommuting and often working nonexclusively for more than one employer. At the same time and for the foreseeable future, the Second Wave Millennials (and soon post-Millennials) will be the fastest growing segment of the workforce. By 2020, those born 1990 and later will make up more than 28 percent of the workforce altogether (including post-Millennials). THE MACRO FORCES CATALYZING CHANGE Many employer’s efforts remain focused on understanding today’s changing workforce, changing workplace, changing nature of employment and even changes in the very nature of work. To that end, the same six profound historical forces of change have been unfolding in plain sight now for more than two decades. These six macro forces continue to accelerate and define the transformations evident in every aspect of life and work.
38 | SEPTEMBER.18
GLOBALIZATION
THE INFORMATION ENVIRONMENT
Unlike any other time in history, we can all look forward to a lifetime of interdependency and competition with a rising global youth tide from every corner of the world.
We are all now forced to think, learn and communicate in a never-ending ocean of information. Our information environment is defined by wireless internet ubiquity and immediacy. We have seemingly infinite access to information and ideas and perspectives – unlimited words, images and sounds.
TECHNOLOGY The pace of technological advance today is unprecedented. Information, computing, communication, transportation, commerce, entertainment, food, medicine, war – in every aspect of life, anything can become obsolete at any time. Possibilities appear and disappear swiftly and often without warning. INSTITUTIONAL INSECURITY Terrorism and environmental cataclysm pose ongoing threats. Governments sometimes shut down or run out of money and great companies conquer or fail. Institutions in every domain have been forced into a constant state of flux to survive and succeed in this constantly changing world.
HUMAN DIVERSITY Each generation is more diverse than the last. That’s true in terms of geographical point of origin, ethnic heritage, ability/disability, language, lifestyle preference, sexual orientation, color, size and every other way of categorizing people. ONLINE IDENTITY Through social media, we are connected to an endless stream of content and in continuous dialogue – forever mixing, matching and manipulating from an infinite array of sources to create and then project
back out into the world our own everchanging personal montage of information and selfhood. IMPACTS ON EMPLOYERS: HUMAN CAPITAL MANAGEMENT IN 2018 As employers are constantly trying to become more lean and flexible, downsizing, restructuring and re-engineering are now constants in the workplace. The question leaders and managers should be asking is this: “What kind of workplace do we need to create to bring out the very best work in the very best people on a consistent and sustainable basis?” Here’s the answer: the successful organization of the near future will have one or more core groups of critical talent, but it will also rely on a fluid, flexible talent pool. The organization of the near future will have a wide repertoire of ways to employ people and leverage talent – full-time, part-time, flex-time, on-site, off-site, telecommuting; as consultants, temps, partners, vendors, franchisors, franchisees; upside down and inside out. Successful organizations will be able to get people on-board and up-to-speed and into meaningful roles very quickly, not to mention ongoing training and development to stay one step ahead of the constantly changing needs for new skills and knowledge.
Successful organizations will continue to cut waste, improve efficiency, implement new technologies in order to streamline operations and eliminate labor, drive employee productivity and try to get more and more work out of fewer and fewer people. Meanwhile, they will be required to pay high premiums with lush benefits and lavish work conditions for in-demand talent – whatever the length of their tenure. Organizations must at least provide some of these “dream job factors” for any employee they want to retain for any significant period of time. THE NEW STAFFING STRATEGY • • • • •
•
Build and maintain a powerful core group Build a large fluid talent pool Figure out more ways to get the work done Treat staffing like supply chain management Commit to constant high-potential identification, leadership development and succession planning Reinvent retention: “We’ll call you the next time we need you.”
THE NEW LEARNING ORGANIZATION • •
Get people on-board and up-to-speed quickly Keep people learning and growing and trying to get better
• • •
•
THE NEW PAY FOR PERFORMANCE • • •
•
•
•
Create a real link between pay and performance Get people excited about earning more of what they need and want Figure out how many ways you can reward people for performance and leverage more resources to use as rewards Transform pay-for-performance into a new kind of “piecework” – reducing long-term fixed rewards and increasing short-term contingent rewards Commit to constant goal and incentivesetting, scorekeeping, and cashing-out in micro-rewards Reinvent compensation: “If you want to earn more today, this week, this month, then here’s what we need you to do today, this week, this month.”
THE NEW RETENTION STRATEGY • • •
•
•
Percentages of each generation in the workforce: 2017 vs 2018.
Figure out how many ways you can make the knowledge available Turn training into heavily supported employee self-building Commit to constant needs-assessment, individual learning plans and teaching/ coaching/mentoring Reinvent knowledge-work: “Everything is knowledge work if you are actively trying to get better at what you are doing.”
Create long-term employees at every level Create dream jobs for superstars Leverage at least some dream job factors for anybody you hope to employ for any period of time Transform long-term employment into an on-and-off and non-exclusive arrangement with regular career planning tied into your staffing strategy Reinvent the “organization man”: “Nobody quits a dream job.” Article excerpted from ‘The Great Generational Shift—Update 2018 white paper’

Three Reasons the Ergo by Aquajet Systems is a Hydrodemolition Gamechanger The three-piece system, comprised of the controller, spine and climber, redefines what’s possible in terms of hydro-demolition efficiency, mobility and affordability. Here are three ways it’s changing the industry:
Proceq Launches Ultra Wideband Ground Penetrating Radar (GPR) in the U.S. Proceq is proud to announce the launch of the GPR Live in all USA markets. The instrument was designed and is manufactured in Switzerland by Proceq AG. The Ultra Wideband GPR Live is the most cutting-edge GPR available today. Proceq’s GPR Live utilizes steepedfrequency continuous-wave (SFCW) technology that’s never been used in structural GPR applications. This allows for clearer and faster concrete inspection. SFCW benefits include: a frequency range of 0.9 to 3.5 GHz for structural concrete applications, maximum peak power of 10 DB, maximum depth range of 28 inches (70 cm), a built-in live-wire detection feature, clear images of both shallow and deep areas and multiple measurement modes.

1. It’s small. The Ergo is compact and lightweight. The controller is about the size of a large suitcase and so light it can be wheeled around a jobsite by hand. 2. It’s affordable. At less than a third the cost of a full-size robot, the Ergo puts hydro-demolition in the hands of contracting companies that have reservations about investing in the larger machines. 3. It packs a punch. Remember that ‘compact’ does not mean ‘watered down’ with the Ergo. It produces four times the water reaction force of hand lances, all while preventing costly rebar damage and operator injuries.

CSDA COMPANY CERTIFICATION is Your Next Step to Success
T
he CSDA Company Certification Program (CCP) is a company audit program specifically for sawing and drilling contractors. Developed by the CSDA Certification Committee, the program provides owners, architects, engineers, general contractors and government officials with an invaluable prequalification tool, improves the knowledge and skills of cutting contractors and enhances their public image. The first of its kind in the industry, the program aims to educate the marketplace that hiring a Certified Company eliminates risks associated with hiring a sawing and drilling contractor who may otherwise be seen as another unknown subcontractor. CSDA is the only association representing the interests of cutting contractors. CSDA Certified Company reps and legal counsel and program auditor, Glenn Purdue, are both available to help with applications and answering additional questions. office. In some cases, I have an electronic copy of the documents. We use an in-house server for data storage rather than an outside vendor. Our safeguards are typical for law firms our size who handle client information, but of course nothing is infallible. None of the information you give me in the application goes to anyone at CSDA, including both its members and its association management firm (O’Brien International).
Contractors will send their applications to Glenn Purdue, who has been legal counsel to CSDA for 20 years. Currently he is a one-person show in certifying applicants for the CSDA Company Certification Program. We want contractors to be familiar and more comfortable with the process of getting certified, so we quizzed Glenn about how this all came to be and how the CCP operates, especially with regard to confidential member information.
Q: Who is Glenn Purdue, anyway? A: I am a Minnesota farm boy, somehow misplaced as a business attorney here in Minneapolis. Chatting with a fishing friend a few days ago, we were jolted to realize that between us he and I have seen 100 years of the practice of law (he is a year older so you can figure his years and mine). I also am Honorary Retired, U.S. Navy, having served in the Judge Advocate General’s Corps for four years of active duty and held in reserve for another 17. I practice business law, mainly in engineering and environmental consulting. I have also practiced in construction, both in the U.S and internationally, for the past 20 plus years. Q: How do you fit in the CSDA Company Certification Program? A: Once the CSDA committee developed the idea and application, they then approached me to be the third party administrator to determine whether an applicant meets the criteria set by the CSDA Board. The criteria are determined by a point system set by the CSDA committee and myself and is based on answers given on the application. Q: Security of our business information seems more important every day. How secure is the information an applicant sends you? A: Your applications come to me, I alone see them, and they are safely stored here in my

Q: Some have suggested that the application asks for too much business information—what do you say to them? A: From my business viewpoint, I think the application is detailed enough but not overly intrusive. My guess is the Committee and Board wanted a program that has some substance—not just send in your money and get a set of promotional materials. For larger firms with more staff, the application seems quite easy. For smaller companies, it may be a little more challenging. That is not so much the application, but the single form of certification. Please note there are templates and mentors available to those companies who need some assistance during the application process, and I have not denied any companies that have completed the application thus far.
my part where applications are complete in about two days; when we have to go back and forth for information it gets longer, but the average is eight calendar days—the longest 34. I am happy to help, just call me at 952-835-4555. That rolls to my mobile after four rings. Q: What are common issues on applications? A: Quality assurance and quality control— written policies that are currently in place. I think training is reasonably good, but smaller firms seem to lag in formalizing their quality process. This is not to say they are not concerned or not actually giving quality. If there are just a few people involved, then each gets to know the others pretty well. My law firm has three lawyers and a legal assistant; we are in close contact so we feel we know how it is going without a big process, or most days, any process at all. That idea tends to not work as well for larger firms. Q: How are renewals handled? A: The Board ultimately decides this. The current program requires renewal at twoyear intervals, or if some landmark change occurs within your company. An example of an event prompting review might be the business being sold or the passing of an active owner. This process is meant to be reasonable and practical. The Program does retain the right to withdraw member certifications, but doing so would be based on some sort of failure to comply or some other disqualifying circumstance.
Q: How quick is the turn on an application? A: Assuming I am not off fishing or riding a motorcycle, pretty fast. Looking back I have done
Glenn Purdue trout fishing.

Concrete Renovation, Inc. has been a CSDA member since 1992. We have enjoyed and learned so much from other members of the association and have made many longlasting friendships. CSDA has always stayed ahead of new and upcoming regulation changes for Patrick Harris its members. One that Concrete Renovation, Inc. 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 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 (including people from our company) who were directly involved in the creation of this program and other training tools. We would be very happy to answer any questions that you might have.

Director’s Dialogue
Future
PATRICK O’BRIEN Executive Director
W
ell, I know at least one person read my last Director’s Dialogue! Thanks, Matt! Feedback is scarce and it is often hard to judge whether my words make an impact. So, it is always nice to hear that someone was challenged to think differently after reading this column. What do contractors and manufacturers think about the future of the industry? It is pretty easy to get caught up in the day-to-day business of keeping up with the demands and challenges of running a business. However, a little planning for the future can certainly make that future brighter and help businesses stay ahead of the competition. Standing out from the competition is arguably more important than it’s ever been in the concrete cutting industry and may even be vital for survival. I have always thought of CSDA, or any other association, as having split responsibilities. On the one hand, an effective association creates products or services that meet the current needs of its members. On the other, an effective association should constantly consider the future and what it can do to help its members have a brighter one. Setting aside time to really think about and plan for the future can often be a challenge for busy business owners whose daily demands are already very timeconsuming. Nevertheless, it’s crucial we all make time. When I began in this industry, so many years ago, it was very common for a contractor to just cut concrete. Suggesting to a contractor that they may want to look at other related opportunities may have easily been considered insulting years ago. A suggestion like this wasn’t always welcomed. However,

over the years, contractors have expanded their services and many now include selective demolition, concrete flatwork, joint sealing, polishing, imaging and more. In fact, some of these additional service offerings now dwarf the concrete cutting business. Is that good? It’s hard to say, as it depends on factors that individual companies face in their local markets. Will it continue? Probably. How can CSDA help a contractor prepare for the future? Training is the area that first comes to mind, as it’s a wise approach when starting in an unfamiliar business. CSDA now offers training in imaging, polishing and selective demolition in addition to its concrete cutting training classes. In the beginning, training was something many contractors resisted. Many felt sufficient enough in their careers and didn’t see a need for further education. Now, training is a staple in the industry. No formal training or safety programs were offered until the first CSDA Cutting Edge class was held in 1993. Today 6,000 students in total have graduated from CSDA classes. Invaluable jobsite skills, sawing and drilling techniques and knowledge of the latest technology are just a few things graduates have used to advance their careers and help their businesses and employers grow. This outstanding achievement would not be possible were it not for the support from our members. So, my question to Concrete Openings readers is what can CSDA do for you today to help you better prepare for the future success of your company? CSDA certainly wouldn’t be the success it is today if we didn’t listen to our members. Please take a few minutes and let us know what you think. We really would appreciate your input and look forward to your responses. Thanks in advance.
