ecently, I had the opportunity to attend the International Concrete Polishing & Staining Conference (ICPSC) in Atlanta, Georgia. I found it to be a very informative conference that focused on this sector of the construction industry. It was apparent that most of the attendees enjoyed the hands-on demonstrations by exhibitors and the instructive seminars on a variety of topics. One of the highlights was a roundtable discussion between industry leaders—some representing CSDA—that focused on current industry challenges. The exhibitions, presentations and roundtable discussions reminded me of the those conducted by CSDA during the association’s annual Convention and Tech Fair. In 2013, this event will run February 28th to March 2nd at Hawks Cay Island Resort in Duck Key, Florida. This is an event that provides attendees with great business sessions as well as useful networking functions. For over 40 years, CSDA has recognized the need for ongoing industry training and provides contractors with an array of classes. The association has also recognized that the industry is evolving, and that contractors are now doing much more than just sawing and drilling. The growth of concrete polishing and staining, plus the increased use of ground penetrating radar in the industry, has prompted CSDA to expand its membership offerings. The result is new membership categories, committees and training classes to cater for contractors

who have either added these services or have made them their primary revenue stream. I invite anyone interested in learning more to contact the CSDA office. These are exciting times in our industry, and I look forward to seeing more new and innovative steps implemented that will keep the CSDA membership growing. As the end of my second term as CSDA President quickly approaches, I would like to take time to recognize the many people who make this association so successful. First, I would like to thank the hard-working Board and committee members of the association. They donate their most precious possession, their time, along with their talents and resources to keep CSDA a vibrant, industry leading organization. Second, I want to thank the CSDA staff, led by Pat and Erin O’Brien. They are true professionals who promote the advancement of the association and the industry throughout the marketplace. The past two years have been both very challenging and rewarding. I have seen our staff and leaders face each challenge presented, focus on a solution and then work towards it until the goal is reached. Based on how CSDA has responded to a changing industry, and through the formation of the CSDA Next Generation, I expect this will continue long after my tenure. I thank you all for this opportunity to serve you and give a little back to the industry and the association. I feel blessed to have had another chance to be President of CSDA.

he need for speed led to a high-octane grinding job at a NASCAR speedway in Tennessee. In response to fan feedback, the owner of the speedway devised a plan to retrofit progressive banking previously applied to the track surface. While the progressive banking on the corners provided benefits for the drivers, fans felt it removed the aggression and physicality from the track. Diamond grinding was implemented to reduce the degree of banking in the upper track groove of the corners and ultimately give the fans the kind of racing they wanted—bumping, rubbing and lots of twisted metal!
CONCRETE
CASES
NASCAR races at Bristol Motor Speedway are known for aggressive driving. The project involved reducing the degree of track banking in the corners by removing approximately 1.5 inches of depth from the existing concrete surface on each corner of the race track. More than 80 tons of concrete track surface were removed from the corners. Work began in April 2012, with a tight schedule of six days per week and 12-hour days to complete the work on schedule—just in time for a Goodyear tire test on the new surface in June. Following the removal phase of the existing concrete surface, diamond rotary grinding was performed to smooth out the abrasive road texture and prepare the track for racing. Bristol Motor Speedway is a NASCAR short track venue located in Bristol, Tennessee. Constructed in 1960, it held its first NASCAR race on July 30, 1961. Despite its half-mile length, it is among the most popular tracks on the NASCAR schedule because of its extraordinarily steep banking, an all concrete surface, two pit roads and stadium-like seating. In 2007, owner Bruton Smith decided the track deserved a facelift. The new surface included progressive banking in the corners, allowing cars in the outside lane to keep up with the inside lane even though the lap was 500 feet longer.

CONCRETE This made for great side-by-side racing, lots of passing and very few incidents. Unfortunately, fans have historically traveled to Bristol to see aggressive driving, cars being shunted out of the way and lots of bent sheet metal. Therefore, the decision was made to return the corners to their original layout. Speedway Motorsports Inc. (SMI) reached out to CSDA member, Penhall Company, to see if the contractor could help them modify the outside lane using the company’s diamond grinding machines. SMI and Penhall Company had previously worked together on several tracks including Charlotte, Dallas, Las Vegas and Atlanta. After much discussion, Penhall accepted the challenge of removing up to 1.5 inches of concrete pavement from the track. The work would involve diamond grinding the surface while working on a 24- to 30-degree slope. “Speedway Motors Inc. has always strived to have safe and exciting tracks, and Penhall Company has been fortunate to partner with them on a number of projects to help SMI achieve that,” said Dave Neal, Penhall Company vice president and project manager for the Bristol Motor Speedway project. David Tomlinson, shop manager for Penhall’s Atlanta office, was responsible for configuring a diamond grinder that would be able to complete the work at on these extreme angles. After two weeks, the company had a machine and a method ready for trial. A Penhall G-38 diamond grinder was successfully maneuvered to the top of the slope on the track and with only minor adjustments, completed the first of several passes. The grinder was fitted with 220 blades measuring 12 inches in diameter. The diamond blades used on the project were supplied by Diamond Products. Operators were able to remove the 1.5 inches of concrete surface quickly, with low vibration and limited noise. Each pass on the Bristol Speedway track measured 3 feet wide as the grinder moved 12 feet across the concrete surface. The outside lane at Bristol Motor Speedway consists of 1,400 linear feet of corner connected by roughly 1,250 linear feet of straightaway. The 12-foot-wide lane required four 3-foot-wide passes. The initial pass was made along the left, or inside part of the lane, and additional passes progressed up the banking toward the outside of the lane. The three major challenges to high-bank grinding are mechanical, lateral stability and center-of-gravity. The first, mechanical, involved assuring adequate lubrication and fluid flow to all of the essential machine components. Lateral stability, preventing the grinder from natu-

The low center-of-gravity on the G-38 diamond grinder used on this project kept the grinder’s center of gravity directly at the diamond grinding head. With each of these challenges accounted for, the margin for error during grinding was greatly reduced. To complete the work as specified, every maneuver required perfect placement and timing. Any sudden move or turn could have resulted in damage to the machine and/or the track surface. At the start of each shift, the entire Penhall crew met for a pre-task planning session for each day’s work. This made sure the safety of everyone involved was considered and helped maintain a high quality of work. The concrete surface was adjusted in time for the speedway’s scheduled Goodyear tire test in June and the first official race at the Bristol Motor Speedway was held August 25—a NASCAR Sprint Cup Series race won by Denny Hamlin. While the intricate grinding and milling process was a challenge for Penhall, the speedway general manager, Jerry Caldwell, said speedway officials were pleased with the results.

CSDA’s Next Generation Learns from the Past to Prepare for the Road Ahead
T
he next generation of industry professionals is faced with a challenging business environment in which to grow. Fewer opportunities lead to more competitive pricing, therefore cost control both on-site and in the office has become even more critical to maintaining margins. The combination of these pricing concerns, together with a tangled web of environmental, health and safety issues, means a tough road ahead for many young business people. While some want to move forward, unsure of what is beyond the horizon, others are looking back at how past generations of business leaders dealt with such important issues. By doing so, they can adapt successful business strategies to a new model or learn from past mistakes and determine how to avoid falling into the same situations. CSDA is bringing these two groups together for the benefit of the industry. The CSDA Next Generation group was formed in 2010, holding its first meeting at World of Concrete in January of that year. The idea for a group of this kind came from a meeting of CSDA Past Presidents. Some have sons or daughters taking an active role in the day-to-day running of their businesses, while others simply saw promising young people within the association and felt there should be a forum specially for them. “The aim was to have a group led by younger members of CSDA, for younger members, to find out what they feel is important about being the member of the association and what they can offer through their involvement,” said Richard Long, a Past President and recipient of a CSDA Lifetime Achievement Award. In the two years that have followed, the group has formed a CSDA committee and several members have taken up active roles within the association. However, the group is still open for others to join and contribute as and when they can. The CSDA Next Generation Committee has organized social events and

team building activities, and is also working with other committees to grow membership and update Best Practice documents for the association. Tablets and smartphones have replaced notepads and ballpoint pens during meetings, and other committees are tapping into the knowledge of this more tech-savvy age group. More importantly, however, members have networked and built relationships with experienced business owners, forming bonds between the two groups. Now, the goal is to bring these generations together in a structured setting to share information and provide real value for all involved. Recently, the Next Generation Committee was asked to provide suggestions for roundtable discussion topics as part of CSDA’s 2013 Convention and Tech Fair in Duck Key, Florida. Naturally, suggestions focused on how this young generation could gain the utmost value from the event, from the relationships forged within the association and from being an active member. The first topic suggested was based on the value of mentoring. This roundtable is aptly called, “If I Knew Then What I Know Now.” The aim of the roundtable is to encourage dialog
and create engaging question and answer sessions between members, with the ultimate goal of having younger participants learn from the successes and failures of their more experienced counterparts. Discussions will focus on employee management, product and service marketing and adding technology to diversify a business. The roundtable will be held in a “speed dating” format, allowing all participants time with each moderator. The second roundtable is titled “So You Think You Want to Buy the Company?” and focuses on business succession planning. The hope for this roundtable, is that it helps to shed light on the processes of buying, selling or transitioning a business to the next generation in a fair and equitable way. A number of participants will have experience of one side of these type of deals, while some may even have experience in both. Next generation professionals will have a great resource from which to extract knowledge—those who have been through it and know the ladders and pit falls involved. Meanwhile, those from an older generation may gain some insight into some of the issues facing up-and-comers in today’s market. A challenging business environment desires a dynamic and innovative response. Through
View from the Next Generation: Several younger members of CSDA participated in a survey about what value they feel they get from their CSDA membership. Here are some of their answers:
Technical Knowledge “Our customer had a saw problem that was cracking his diamond blades, but I could not put my finger on the problem. I called two competitors that I have known for years through CSDA. They gave me some solid suggestions, and we solved the problem. These relationships saved me a trip to see the customer and saved us a product return. We saved at least $5,000 in time, travel and product replacement. We also earned credibility with the customer by quickly giving them a “proper” solution.”
What is a Roundtable Discussion? Participants sit at a table and discuss a series of pre-determined topics for a set amount of time. At the end of each time period, a spokesperson from the table gives a summary of the pertinent points raised to the rest of the room. If attendance is large and multiple tables are filled, moderators can be assigned to ensure discussions remain on topic and that each table has an opportunity to share the results of their discussions.
Sid Kilgore, Dixie Diamond
Networking “This past year, the company was awarded two jobs due to its reputation. The referrals came from other CSDA members. Holes Incorporated performed over $20,000 worth of business with the two general contractors. Also, a peer in Illinois sent me a very good contact for an electrical contractor moving to Houston, which I am hoping will lead to more work. Personally, I learn a lot more from talking with other members at CSDA meetings than any other resource.” Kellie Vazquez, Holes Incorporated
“Shortly after I purchased the company, we re-joined CSDA. For me, getting involved in CSDA has been beneficial, both in terms of generating contacts in the industry and taking advantage of educational sessions presented at the annual convention. CSDA also provides a broader view of the industry than I can get from our local area, providing the opportunity to discuss the pros and cons of equipment with colleagues from around the country. All of this contributes to our ability to improve our productivity and performance for our customers.” Matthew Finnigan, National Concrete Cutting
the creation of the Next Generation Committee, CSDA has placed itself at the leading edge of that response. For those looking to take their concrete sawing, drilling, grinding, breaking, recycling, polishing or GPR imaging business into the future, the answer may lie in the past. The good news is that you do not need a Delorean or a crazy scientist to reach the information you seek. CSDA has a diverse membership with a wealth of experience, and many are ready and willing to share their knowledge with the next generation. For more information about the association’s Next Generation Committee or the CSDA 41st Annual Convention and Tech Fair (February 26 to March 2, 2013), call 727-577-5004 or visit www.csda.org.
Certification “DeAndrea Coring and Sawing’s CSDA membership has helped in several ways, but industry certification has given us a great advantage. Networking with fellow CSDA Certified Companies during the certification process was invaluable, and we hope to pass on what we learned to others. We estimate around $48,000 of sales has been awarded specifically because of our industry certification and the valuable resources CSDA provides. Potential customers have recognized our professionalism and what sets us apart from the competition.” Paul DeAndrea, DeAndrea Coring and Sawing

Won’t Crack Under Pressure Cutter Keeps Cool to Help Remove Damaged Concrete Slab
When a damaged concrete slab needed to be removed from the basin of a 600 foot-long, 250-foot-wide graving dock in Corpus Christi, Texas, one CSDA member had to bring in a fleet of cutting equipment to complete the job.

he concrete slab measured up to 39 inches thick in some areas, but hydrostatic pressure in the ground below the slab had caused it to crack and break. The upward movement of the ground had pushed broken concrete sections up from the slab and created hazards for the keels of docking ships and the positioning of support blocks. Vessels are floated into graving docks and positioned on blocks before the dock is drained of all water so crews can perform maintenance or repairs on the vessel in a dry environment. The displacement of the earth beneath the basin floor had also caused damage to parts of the dock’s drainage and pump systems, rendering them unusable until the slab could be removed and repairs made. The broken and cracked areas of the slab were to be demolished, removed and replaced. As part of this project, CSDA member Concrete Cutting & Breaking Co. was contracted to use sawing and drilling techniques and create sections of concrete that would be manageable for the general contractor—CCC Group, Inc. of Corpus Christi—to remove by Tools and equipment were lowered to the dock basin by crane. crane. The speed, low vibration and precision associated with diamond tools was the best way for the damaged slab to be removed while keeping certain parts of the floor.

Both systems were to be repaired and reconnected to the functional parts of the graving dock’s pit de-watering system when the job was completed. The type of aggregate used for the basin slab also presented a challenge. Operators would have to cut through extremely hard concrete with a hardness of 9 on the Mohs scale, which included quartz, chert and flint. The basin had a top mat with #8 rebar at 5 inches on center in each direction, while the bottom mat had #10 rebar at 5 inches on center in each direction with 6-foot-long lap splicing. Concrete Cutting & Breaking devised a plan with CCC Group to cut the concrete into uniform square sections so that the slab pieces could be removed by 360 class excavators. The pieces would then be transported to the sides of the graving dock pit, where rigging would be installed to lift the pieces out by cranes positioned at the edge of the dock walls, 40 feet above the basin floor. Slab thickness differed at Wire saw units from several locations across the U.S. were brought to the dock.

others would fall. This led to “slamming” of blades and wire, which when placed under that amount of pressure, caused instantaneous and irreversible failure of these tools. However, the contractor was prepared and well stocked with spares. Obviously a job of this scale required a lot of equipment. In addition to the five wire saws and four slab saws manufactured by the contractor, the team used three 120-horsepower slab saws from Diamond Products, four 1,500-gallon water tanker trailers and pump systems, seven service trucks and vans, various diamond blades from Diamond Products, Diamond Tools Technology and Husqvarna ranging from 26 to 96 inches in diameter and diamond wire from Diamond Tools Technology, Husqvarna and Diamond Products. The project was completed September 28, 2012, as scheduled. The general contractor was then able to enter the site and begin repairing the damaged parts of the dock’s drainage and water pump systems, before replacing the cut sections of concrete. Concrete Cutting & Breaking would like to thank its employees and the general contractor, along with Randy Wendel of Diamond Core, Mike Hogan of Diamond Products, Clay Morphis of Husqvarna and Mark Turner of Diamond Tools Technology for their patience, perseverance and support during the work. This combined effort led to another successful job for the contractor.

The Business of Business
How Real Are Those Price Pressures? by George F. Brown, Jr.
D
ecisions on pricing are almost among the toughest ones facing business executives. Customers and competitors alike put tremendous pressure on firms that raise prices. At the same time, ongoing increases in the costs of health care benefits, energy, raw materials, wages and other factors cannot be easily overcome without price increases. The question most often asked in discussions about pricing is “How real are those price pressures?” If they reflect fundamental market forces, price increases can translate into a serious erosion in market share. If they involve posturing and negotiation tactics alone, price increases can remove a lot of the pressure on the coming year’s annual plan. Four fundamental indicators can help to determine if price pressures are real or not. Each of these can be measured, and provides solid insights into the characteristics of a firm’s business environment that impact pricing decisions. These indicators are useful in multiple ways. In addition to helping to identify price pressures that must be taken seriously, they are useful when monitored over time and when evaluated from one product line or service to another, or from one market segment to another. Monitoring these indicators over time can spotlight instances in which a product or service is evolving towards commodity status, with the obvious implications of such a migration in terms of future margins and the need to focus on ways of reducing costs. Evaluating these indicators across product lines, services and market segments can allow a firm to focus price increases appropriately, thereby avoiding a strategy that is on average right, but wrong for every product, service and market segment. One executive commented that his sales team’s philosophy seems to be to respond to every price challenge that is encountered. That strategy might avoid an occasional loss of business to a competitor, but it has adverse longterm implications. In CoDestiny, we discuss the trap of falling unnecessarily into a vicious cycle of price-based competition. Firms that do so subsequently find themselves having to
2 0 | d e ce mb e r.1 2
reduce investments in product development, high-value services and other ways in which they respond to customer needs and differentiate their offering. As they do so, their products become more and more of a commodity, and price cuts become the only way in which they can win competitive battles. The first indicator that defines the strength of pricing pressures is the capacity balance in the industry. Simply stated, the more excess capacity that exists in an industry relative to demand, the more real and intense pricing pressures will be. This indicator can change rapidly over time as demand moves with the business cycle. It also can change in a significant step-function way as firms build new plants or shutter older ones. To a significant extent, this indicator is one that is largely outside the control of the individual firm. It can make decisions on its own capacity, but except in a few unique industries, the overall capacity balance is determined by other industry participants. The capacity balance is a very significant indicator; in industries with a massive overhang of unused capacity, the pricing pressures will be incredibly intense, almost overshadowing any favorable implications that might be seen in the other three indicators. The second indicator involves the degree of “protection” that exists for the business being examined. Protection can be legal in the form of patents or copyrights, but it also can involve the degree of customization, engineering, design or service embedded into the product. The evidence is strong that such value contributions place implicit barriers to competition and impose significant costs of change on customers that shift
suppliers. The customers that elect to buy products or services which are customized or highly engineered, do so because of the value they get from them; as a result, they are not likely to casually shift to another company with increased risk of disappointing results. In a common sense way, this indicator reflects the fact that when a company’s offering includes elements that are of high value to customers, that company should be able to capture some of that value in their pricing. The third indicator focuses on the business environment into which the company is selling. In healthy business environments, pricing pressures are less intense and less real. The measures of health involve not only the company’s direct customer, but even more so the customers at later stages further along the customer chain. Every business has seen occasions when everyone is scrambling to keep up with demand. In those circumstances, price challenges are often the furthest thing from everyone’s mind. And every business has seen unhealthy markets, ones in which finding a customer is itself a challenge. In those situations, the tendency is to look back at the supply chain and battle for every dime. Pricing pressures travel along the customer chain. If a participant at any stage of the customer chain, from the lowest tier company to the final end customers that use the product or service, is facing a difficult business environment. The implications tend to ripple along the customer chain, another manifestation of the old saying that a chain is only as strong as its weakest link. The fourth indicator focuses on the relationship between the supplier and the customer. There are two basic elements to this
indicator. On the positive side, instances in which the parties consider each other a “strategic supplier” or a “strategic customer” are ones in which pricing pressures are likely to be less intense. This isn’t to suggest that buyers become soft in strategic relationships. Rather, the reality is that other elements to the relationship are far more important than price, and pricing rarely dominates the agenda of meetings between the two organizations. In strong relationships, the firms involved have largely solved the pricing issue, and can quickly reach agreement and move on to more important topics. On the negative side, research indicates that the companies that rank among the customer’s largest, companies whose products and services are expensive and companies whose products represent a significant portion of their customer’s product cost structure, sit on the bulls-eye. They attract the attention of both purchasing managers and competitors. In the context of various consulting projects, we’ve examined these indicators in many diverse industries and economic environments. Over and over, the result has shown significant variation from product line to product line and from one market segment to another. Such learning has allowed firms to make pricing decisions that were appropriate to the business environment in which they were operating, and to do so on a segment by segment basis. Occasionally, the process has spotlighted sharp shifts taking place from one time period to the next, allowing firms to make forwardlooking pricing decisions. The process has also allowed firms to uncover quite a few surprises in the indicators and their implications. These surprises have been in both directions, some positive ones where firms had inappropriately accepted pricing challenges as an ongoing reality and some negative ones in which firms had been unaware of the pressures that were sure to come. A real strength of this approach is the rigor that it brings to discussions of pricing, allowing firms to get beyond the latest “war story” and to discuss pricing options from a factual base.

Mactaquac Generating Station, New Brunswick, Canada
CASES
Parts of the Mactaquac Generating Station were affected by Alkali Aggregate Reaction.
Stress Relief for Big Dams
Wire Sawing Relieves Concrete Stress Caused by AAR Evidence of distress in a concrete dam at a Canadian generating station called for swift action to maintain safe working operations. Investigations determined that the end pier of the dam spillway was cracked internally and the cause of the problem was identified as Alkali Aggregate Reaction (AAR). A contractor was needed that could create large vertical slots through the concrete structure quickly and cleanly. AAR is a deleterious chemical reaction in hardened concrete. The reaction occurs between reactive aggregates and alkalis in surrounding hydrated cementitious paste. The reaction produces an expansive gel formed at or near the paste/aggregate interface. With concrete at an internal relative humidity of 85 percent at 68 degrees fahrenheit, the gel absorbs water and increases in volume. This gel expansion disrupts the paste/aggregate bond and cracks surrounding paste. Concrete afflicted by AAR results in expansion, causing increased internal stresses that eventually result in cracking. Many concrete dams and structures throughout the world suffer from AAR. Constant monitoring and continued remedial actions are required at these structures to judge the magnitude of expansions and counteract this expansion and prevent damage to joints or impair gate operation. One such counteraction employed by Mactaquac Generating Station, close to Fredericton in New Brunswick, Canada, is slot cutting concrete with diamond wire to relieve the internal stresses caused by this expansive reaction. www. c on c re te ope n in gs.com

The Mactaquac Generating Station, owned and operated by New Brunswick Power, is located on the Saint John River approximately 20 kilometers (12.4 miles) upstream from Fredericton. The station is the largest hydroelectric generating facility in the Maritime Provinces. Constructed in stages between 1964 and 1980, the facility has an installed capacity of 672 megawatts produced by six turbines. The facility consists of the intake structure, two concrete spillways, a diversion sluiceway and the intake spillway. Each structure contains five, 14-meter-wide, 16-meter-high (45.9-footwide, 52.5-foot-high) spillways. Distress in the concrete structures at Mactaquac was first noticed in the mid-1970s with the increasing opening of a longitudinal joint in the powerhouse substructure. By the early 1980s, leakage through horizontal joints in the spillway, intake and diversion sluiceway structures was evident. At this point, New Brunswick Power decided to install instrumentation in the foundation rock and within the concrete substructure to check for the possi-
bility of a phenomenon such as rock swelling that may have been the cause of distress. In 1985, spillway gate 10, adjacent to the intake structure, was found to be obstructed. A differential displacement of the spillway end pier toward the gate opening in excess of 25.4 millimeters (1 inch) was noted. It was at this point that the end pier of the spillway was found to be cracked internally. The cause of the detrimental expansion and subsequential cracking was then identified as AAR. After the problem of expanding concrete was confirmed, it was decided that slot cuts would be made in the intake structures to relieve deformation of the spillway and piers. The first slot cut was made in 1988 within the intake structure. The slots disrupt the continuity of the adjacent expanding concrete, thereby reducing the magnitude of the deformations pushing at gate openings. Smaller deformations realized in the concrete adjacent to gate equipment resulted in improved operations. A side effect of cutting the concrete is that cutting reduces confinement or restraint of

the concrete, thereby allowing an increased expansion rate of the concrete. Depending on the width of the slots, re-cutting will be needed in the future to maintain manageable movements that do not interfere with gate operations. Instrumentation located throughout the structures record data that is used to determine the frequency of each re-cut. In general, the intake cuts are made on a three-year cycle, the diversion spillways on a two-year cycle and the powerhouse locations are cut on a six-year cycle. To date, 28 slot cuts have been made at the station. Cuts are positioned to ensure they are below any of the openings and embedded parts that may be affected by the expansion. Below this point, the mass of concrete is continuous. The increase of stress in this area does not cause any damage to concrete joints or moving gates. CSDA member Cutting Edge Services Corporation of Batavia, Ohio, was contracted to return to Mactaquac and make a 25-meterdeep (82-foot) slot cut in the dam spillway that would range from 12 to 30 meters wide (39.4 to 98.4 feet). The CSDA Certified Company
had already performed wire sawing work at the station and the cutting team was familiar with the task presented. “We had previously used a “pull” technique to re-open the slot in the diversion dam structure, advancing the saw along its track system to take up slack created by pulling the wire through the structure,” said Joe Shebesta, project engineer for Cutting Edge Services. “We also used a “push” technique to re-cut the intake slot between monoliths 4 and 5.” Push cutting or “downhole,” is done by lowering pulleys into a cofferdam on the upstream face into pilot holes in the deck and by various pulleys located on the downstream face. The 25-meter (82-foot) slot was cut in stages, from the top down. The first stage pushed the wire into the gallery and close to an active electric cable tray. This cut was carefully monitored to prevent severing of the cables and took approximately eight hours to complete. Then the wire was cut and the cables moved upward. More pulleys were added and the wire was reconnected for completion of the lower stage, taking 20 hours. When the wire reached
What is AAR? Alkali Aggregate Reaction (AAR) is an internal reaction that occurs when alkalis in cement react with reactive aggregate particles. There are two main types of AAR, alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR). ASR is the more common of the two, and is the type of concrete expansion impacting the structure at Mactaquac Dam. During the process of ASR, a gel is formed around the aggregate. If the gel is exposed to moisture, usually if the relative humidity of the concrete is higher than 80-85%, it expands, causing the concrete mass to expand. The result of this expansion on large concrete structures can be unsightly cracking, although the structural integrity may not be impaired. However, major operation and maintenance problems may occur, such as binding of gates, cracking of piers and misalignment of equipment such as generators.

the minimum cut depth 25 meters (82 feet), the “down” pulleys were brought up. Cutting of the upstream stage was then performed, using downhole systems in the cofferdam and the pilot hole. The upstream cutting was completed in 30 hours. Cutting Edge Services used a unique hydraulic-driven machine that was custom fabricated to feed 3.3-meter-long (10.8 feet) sections of aluminum tubing downward. The system is capable of plunging down to a depth of 33 meters (108.3 feet), but was only required to plunge 25 meters (82 feet) on this job. All cuts at Mactaquac were maintained using 15-millimeter-diameter (0.6-inch) electroplated diamond wire supplied by Norton Pro Diamond. This was a directional rubber injected wire, providing added strength to the wire assembly and minimized breakdown of the wire caused by concrete slurry. The wire was constructed with 40 beads per meter and a 4.9-millimeter (0.2-inch) base cable. The length of diamond wire used was approximately 100 meters (328.1 feet) and there was lots of contact area with the concrete, so
Conditions Required for AAR: High alkali content of the cement Reactive aggregate High moisture/water
Remedial Efforts to Control AAR: Concrete affected by AAR does not continue to expand throughout its useful life. This can be due to loss of moisture, but more commonly from the depletion of alkalis. The chances of a successful repair of structures that continue to exhibit AAR expansion are very low. Structures such as Mactaquac Dam can have its useful life expanded by implementing maintenance programs to alleviate the expansive forces resulting from the effects of AAR. Since the 1980s, various remedial measures have been performed on the head works at Mactaquac, including: •
Modifications to the gates, guides and towers of the spillway, diversion sluiceway and intakes
•
Chemical and cement grouting of the various structures to control leakage
•
Reconstruction of bridge deck expansion joints at the spillway and the diversion sluiceway to re-establish eliminated clearances
•
Slot cuts

The average speed of the wire saw was 1,200 meters (3,937 feet) per minute.
the average cutting speed was around 1,200 meters per minute (3,937 feet). Pressure on the wire was relatively low to maintain wire speed and deal with concrete slivers and debris in the cut line. Gauge pressure at the power unit was in the range of 2,500-3,000 psi. Connections in the butt joints of wires were monitored and replaced at 2-4 hour intervals and cutting was performed around the clock. The use of wire sawing techniques increases overall safety, as operators can remain a safe distance from the cutting area and operate the saw by remote control. Cutting Edge Services made sure all operators were equipped with the correct personal protective equipment and tied off when working at height or near large drops. “Diamond wire sawing systems are ideal for making slots in mass concrete structures. Maintaining slots at Mactaquac Generating Station is an effective way of dealing with expansion of concrete caused by AAR. Continued improvements in diamond wire and equipment technology are increasing the efficiency of performing this work, and it is hoped that we can continue to maintain safety and smooth operations at the station in the future,” said Tim Beckman, owner of Cutting Edge Services.

Cut Alcohol and Drugs from Your Workplace: A Contractor’s Guide to Drug and Alcohol Policies By Kellie Vazquez
W
ith the holiday season in full swing, many people are seeing family, catching up with old friends or attending social functions. Often, the festivities involve alcohol and, although less often, may wrongly include the use of drugs. While the abuse of drugs or alcohol may take place outside of working hours, the effects of this abuse can spill over into the workplace. If either are used during work hours, a potentially dangerous situation may occur. When combined with the use of a motor vehicle or heavy tools and equipment, the misuse of alcohol and drugs can have serious, even fatal, consequences. It is important to remember that alcohol can remain in a person’s system for up to 12 hours after consumption, depending on the amount consumed. For some drugs, evidence of use can be detected days or even weeks after use. Therefore, a person can still be over the legal limit the morning after drinking alcohol. This person may be driving others to a jobsite in a work truck or operating sawing or drilling equipment. CSDA strongly supports measures that contribute to a drug-free environment and reasonable use of drug testing within a comprehensive workplace program, such as those involving safety-sensitive duties like operating concrete sawing and drilling equipment. Recent reports suggest that the construction industry has one of the highest rates of illicit drug use among workers. Implementing a program for a drug-free workplace is imperative to having a safe place to work. The following information is intended to give employers an insight into typical drug and alcohol policies, commonly-used terminology and details some of the testing procedures in place among contractors.
2 8 | d e ce mb e r.1 2
Policy Terminology The term “employees” is meant to include employees of the company, and employees of the company’s affiliates, subsidiaries, contractors, subcontractors, vendors and their employees. The terms “workplace,” “work-site,” “premises” and/or “company property” and like terms are meant to include all properties, facilities, lands, platforms, buildings, structures, fixtures, installations, boats, aircraft, automobiles, trucks and any/all other vehicles, equipment, whether owned, leased or used. The term “illicit drugs” is meant to include any and all illegal drugs, including so-called look-alike or designer drugs; legally obtained drugs which are obtained in a manner other than that prescribed by a licensed physician; and any substance which can affect a person’s perceptions or motor functions. Some exam-
ples of illicit drugs are cannabis (marijuana), cocaine, heroin, phencyclidine and alcohol. The term “possession” is meant to include the presence in the body or the custody of an illicit drug or alcoholic substance. The term “biological testing” is meant to include the collection and analysis of urine, blood, saliva, breath, hair, tissue and other specimens of the human body. The term “for cause” is meant to include accidents, incidents, near miss reports, erratic conduct suggestive of drug or alcohol use and similar performance behaviors. The Safety Director and Safety Administrator will be responsible for conducting/ sending employees for drug and alcohol testing. They are also responsible for communicating results with the company owner and retaining the information in the employee medical file located at the main office.

safety counts Safety Documentation from CSDA
Employee Drug Testing Procedures
A 230-page CSDA Safety Manual has been developed to assist concrete cutting contractors in establishing safety and health programs that will benefit both employees and owners. The manual is intended to provide a starting point for developing company-specific safety programs. It is divided into a Field Safety Manual, Reference Section and a questions and answers section. The Field Safety Manual is intended for the operator in the field to use to identify company specific safety policies related to key issues of operation. The Reference Section is designed to serve as a guide on additional topics that may affect the overall company safety program. In addition, the CSDA Safety Committee works to release a Toolbox Safety Tip (TST) to the membership every month. There are currently 100 TSTs in circulation on a wide range of subjects related to the industry. All TSTs are available to download in PDF format from the Member Section of the CSDA Website. For more information, call 727-577-5004 or visit www.csda.org.
Each employee is subject to medical or physical examinations or tests, including viewed urine drug screen tests, as a condition of continued employment. Testing should be carried out under the following conditions and any resulting action is at the determination of the employer:
DITEQ BOOTH C4641
Pre-Employment/Pre-Access Testing Each applicant for employment will be required as a condition of employment to submit to a viewed urine drug screen test. If an applicant tests positive and is determined to be in violation of this policy, the applicant will be ineligible for employment. Reasonable Cause to Suspect That the Employee is in Violation of This Policy When a supervisor suspects an employee to be in violation of this policy, the employee will be asked to stop working and be driven to a medical facility for drug and alcohol testing. The Safety Director can also test the employee for both. The incident will have to be written up by the supervisor who witnessed the behavior. All supervisors have been trained in “substance abuse.”

TS-092 3 Speed
Post-Accident/Incident The urine test and breath analysis test will be conducted at a medical facility after examination when involved in an accident or incident. Employees not tested prior to medical treatment because of emergency situations will be immediately tested before returning to the job-site. Random/Annual Testing The unscheduled, unannounced drug testing of randomly selected employees by a process designed to ensure that selections are made in a nondiscriminatory manner. An employee who refuses to submit to drug abuse testing as outlined in the company’s policy will be subject to disciplinary action for failure to comply with the Substance Abuse Policy Procedure and escorted off the job-site. Conditions for re-employment of former employees discharged for refusal to submit to drug testing will be the same as for an employee who tests positive and is determined to be in violation of this policy. Employer Responsibilities • Train employees on company policies and procedures • Train supervisors in substance abuse awareness • Keep employee records confidential, maintaining each employee’s right to privacy • Train employees of the dangers of working under the influence of alcohol and illicit drugs and some over the counter and prescription medications • Have employees sign off on a consent form allowing drug/alcohol testing results to be released to the employer All employers and employees are encouraged to be aware of the drug and alcohol policies in place at their companies, or implement such a policy to reduce the chances of jobsite incidents relating to these substances. If there is any doubt about a person’s ability to drive a truck or operate a piece of equipment due to a previous night’s drinking, that person should not be allowed to do either. Furthermore, the rules of the policy should be enforced. The time spent with family, friends and coworkers during the holiday season is to be enjoyed, but everyone should drink responsibly and avoid the use drugs.

Selecting a Planetary Concrete Grinder By Jamie Krueger
T
hanks in part to “green” building, one of the fastest growing flooring options in recent years is polished concrete. There are many advantages to polished concrete when compared with other types of flooring. Polished concrete is a highly durable surface with a high resistance to scratching, low maintenance and high reflectivity to light—decreasing the number of light fixtures needed. Because polished concrete is such a fast growing segment in the construction industry, there are many manufacturers of planetary concrete grinders/polishers vying for business. Some of these manufacturers offer numerous models of grinders/polishers with all sorts of
3 2 | d e ce mb e r.1 2
features and benefits, so determining which unit is correct for a particular application can be a difficult decision for any contractor. This decision can affect operators, schedules, final floor finishes and ultimately, the company’s bottom line. Choosing the Correct Grinder When looking to purchase a planetary concrete grinder/polisher, there are many factors a contractor has to take into consideration. Matching Applications Since concrete grinders/polishers are very versatile machines and can perform many different applications—from concrete
surface preparation and concrete polishing to removing materials over the concrete—a polishing contractor needs to determine which application will be performed most often. It is very important to match the planetary grinder/ polisher with the right application. Making sure the unit can perform the required treatment is critical to finishing a job correctly, and can directly affect a contractor’s bottom line and reputation. In any industry, it is imperative a company handles its first few jobs well to grow and strengthen its reputation in the market. A contractor needs to decide if their company will be bidding on large commercial projects or trying to acquire smaller or residen-
MALA CX12 Concrete Imaging System
tial projects. Contractors might only want to offer removal services—the removal of glue or epoxy, for example—or light polishing applications. Using the wrong machine with the wrong application will drastically affect profitability. For example, if a contractor attempted to tackle a 100,000 square foot polishing job with one 21-inch-diameter grinder/polisher, the job would take too long and the machine most likely would not perform at its optimum level.
Scanning Structures for Non Destructive Evaluation
Power Availability Another factor to be aware of is the correct use of power for the unit. Most planetary grinders/polishers are electric powered and run on 220V single-phase, 220V threephase or 480V three-phase power. Single-phase machines can use power from a 220V outlet and are great for smaller commercial or residential jobs. Since an additional power source is not needed, the singlephase machines make setup and tear down quick and simple. The three-phase machines use power more efficiently and therefore are more powerful. However, three-phase power is not accessible in all facilities, thus there is a need for a secondary power source, such as a generator. Some specialized facilities do have three-phase power available, so it is always important for the contractor to check with the facility.

Differences in Planetary Grinders/Polishers The planetary grinder/polisher is one of the most common types of concrete grinders available on the market. It is composed of three, four or six satellite heads that spin in conjunction with the large planetary drum. There are four basic designs of planetary grinders: unrestricted planetary, restricted planetary, driven planetary and dual motor planetary. Unrestricted Planetary In unrestricted planetary grinders, the satellite heads spin on the floor and the planetary drum spins with the satellite heads. This means there is no planetary control. The planetary drum always spins in a counter-rotating direction, meaning if the satellite heads spin in a clockwise direction the planetary drum spins in a counter-clockwise direction or vice versa. The advantage of an unrestricted planetary machine is the low cost. It is a good choice for a contractor that is just entering the surface preparation and polishing industry. The disadvantage is that it has no planetary control, which means it is very weak in grinding applications.
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 | 3 3
t e c h ta l k Restricted Planetary The restricted planetary grinders have a planetary operation that is driven by a clutchtype mechanism using a belt. This type of grinder has a stable operation and creates more friction between the diamonds and floor. The planetary control makes it more aggressive than unrestricted planetary grinders. Just like on the unrestricted grinders, the satellite head speed works in conjunction with the planetary speed. This means it does not perform well
on applications where low planetary speed is necessary, as the head speed will also be low. Since the restricted planetary grinders are belt driven, contractors should be aware that the planetary action causes the belt to slip while removing heavier materials. This can lead to excessive wear on the belt. Driven Planetary Driven planetary grinders are similar to the restricted planetary grinders, but instead of a belt mechanism, driven planetary grinders are
operated by gears. One major difference is that the heads can either turn in a counter-rotating direction or same direction as the planetary drum. This can sometimes depend on the manufacturer’s specifications. If the grinder is geared to spin the planetary and satellites in the same direction, then the grinder will be much more aggressive during grinding. The disadvantage to this grinder, like the unrestricted and restricted models, is that the planetary drum still speeds up or slows down in conjunction with the satellite heads. Dual Motor Planetary

The planetary function on dual motor planetary grinders is operated via a driven gear mechanism while the function of the satellite head is driven by a belt. This provides fully adjustable speed and fully adjustable direction control for planetary and satellite heads. The advantages are that dual motor planetary grinders have independent setting controls for planetary and satellite heads, enabling optimum setting control for all applications. This type of grinder has higher production rates during heavy removals due to the ability to spin both planetary and satellites in the same direction and tailors the speed settings specifically for the application. The disadvantage to dual motor planetary grinders is the wear on the operator. The resistance caused at the handlebar due to the aggressive nature of heavy removals can cause the operator to become fatigued. There are major advantages and disadvantages of each of the four planetary grinder/ polisher options available. One of the best ways a polishing contractor can decide, after looking at exactly what applications they will be performing, is to run the machines. Operating each type of grinder will enable a contractor to feel and see the differences, then choose the grinder that is right for their business based on the results. Please note: Even if the correct grinder is chosen for a particular application, contractors must also choose the correct diamond tools to use with the machine and application. Grinders/ polishers and diamond tooling work must be used hand-in-hand to make sure a project is completed on schedule, within budget and with a great end result.

CORE HEALTH
Sugar–the Good, the Bad and the Ugly By Erin O’Brien
W
e’ve all heard it before—sugar is bad for you. More recently, the enemy has been high-fructose corn syrup—a chemically modified version of sucrose (table sugar). However, even the most basic chemistry or biology class teaches that bodies run on sugar, more specifically glucose—sugar in its most basic form. So how can some types of sugar be good and some bad? The quick answer to this question is moderation. Almost any type of food we put in our bodies is acceptable and safe, as long as it is eaten in moderation. Glucose, sucrose and fructose are all types of sugar naturally existing in the food we eat. The difference comes from the way our bodies process each type of sugar. Sucrose and fructose are broken down from their more complex structures to make glucose once inside the body, which is then used for cell energy and growth. All three of these types of sugars are naturally-occurring, meaning they are naturally found in foods like fruits, root vegetables and honey. High-fructose corn syrup is chemically modified from its natural form, corn syrup, by increasing the amount of fructose. The modern problem with sugar, is that as a general population we eat too much of it. Our bodies have a finite amount of sugar that can be processed at one time, and if there is an excess in the body the sugar is converted to fat and stored. Too much sugar in the bloodstream can also raise insulin levels. Insulin is a hormone produced by the pancreas. It tells the body to utilize glucose (sugar) in the bloodstream for energy and also use fat stores if there is not enough glucose in the blood. Too much glucose in the blood, however, will elevate insulin levels and “trick” the body into storing glucose as fat instead of utilizing it for energy. We all know that excess fat equals excess weight, and excess weight leads to a host of health concerns. The other problem with too much glucose in the blood is that is also raises
3 8 | d e ce mb e r.1 2
the level of triglycerides and cholesterol, especially low-density lipoproteins (LDLs). LDL is a type of protein that transports cholesterol around the body wherever it is needed. Unfortunately, if there is too much LDL cholesterol in your body, it ends up getting deposited along the walls of your arteries, causing plaques which can lead to cardiovascular disease (CVD). High-fructose corn syrup can compound this problem. A diet high in highfructose corn syrup, or any sugar, will cause the liver to convert fructose to fat, also leading to increased levels of LDL.
The modern human diet, especially in the United States, is very high in added (or not naturally-occurring) sugars and processed carbohydrates. Combined with a low intake of fruits, vegetables and whole grains, as well as sub-optimal lifestyle habits, physical inactivity and use of tobacco, this is a recipe for disaster. This type of lifestyle leads to an increased risk of obesity, CVD, type 2 diabetes and cancer. It produces a tremendous amount of premature deaths, lost quality of life and global economic disruption due to skyrocketing health care costs.
Diet soda, perceived by some as a “healthy” alternative, is also to blame. While some think that they are making a healthy choice, there is added sugar in diet soda too. Often times, these sugars more closely resemble chemicals than actual sugar and contribute to an increased risk of developing coronary heart disease, kidney disease and metabolic syndrome. One study shows that middle-aged men and women who consumed more than one diet soda per day had a 30% higher risk of developing these diseases. Those with the lowest incidence of these conditions drank one or fewer diet sodas per month. Some recent research has focused on cancer’s relation to sugar in the diet. While no study has been conclusive to date, several suggest that a high dietary sugar intake actually causes some cancer to grow and spread— especially breast and colon cancer. This is because cancerous tumors have insulin receptors that feed on glucose. If there is too much sugar in the body, insulin production goes up and that insulin tells the cancer cells to grow. While much of this research is new, there are many cancer and CVD patients that have attested to the success of a low-sugar diet. We cannot avoid sugar altogether, as it is our body’s main source of fuel and found in most of the foods we eat, but it is important to limit the amount we take into our bodies. This can be easily done by eating a diet high in fruits, vegetables (especially raw) and lean proteins and avoiding processed foods and added sugars and chemicals. Shop the perimeter of the grocery store, as that is where the healthiest foods are, and visit local farmers’ markets for even fresher produce grown with fewer, or no, chemicals. A healthy diet is a balancing act, but can be done by making smart choices. The long term benefits will far outweigh any perceived negatives and produce a higher quality of life for anyone willing to make the effort.

Holey Smoke! Contractor Core Drills Giant Chimney Stack A sawing and drilling contractor scaled new heights to complete a contract for the world’s second most geographically diversified steel producing company.
O
wners of Tata Steel, a top-ten global steel maker, had decided to install specialist monitoring sensors to a 108-meter-tall (354.3-foot) red brick chimney stack at the company’s Scunthorpe plant in the U.K. The sensors would monitor waste gas produced by the plant to safeguard against reaching unsafe levels of toxicity. The plan was to place these sensors at specific intervals on the stack. It was decided a specialist diamond drilling contractor would be required for the drilling of both the ring locating pin holes and the monitoring sensor holes. Fabricated steel bands would then be fixed to these sections of the stack, using steel locating pins, before the sensors were mounted in position. Tata Steel has 15 locations throughout the U.K., seven in North America and many more across the globe. The Scunthorpe plant is home to the company’s Long Products Hub. Here, the steel maker is able to roll rail up to 120 meters long (393.7 feet), a first for the U.K. and of significant interest to rail customers as they endeavour to improve safety along their networks. Steel from the plant has also been used in a wide range of applications, from the construction of the Petronas Towers in Malaysia, the T’sing Ma Bridge in Hong Kong and Wembley Stadium, to simple every day objects such as paperclips and light bulbs.

Each hole measured 150 millimeters (5.9 inches) in diameter and was 300 millimeters (11.8 inches) deep.
CSDA Updates Core Drilling Specification The CSDA Standards and Specifications Committee recently revised the association’s core drilling specification to clarify ownership of cored holes. Under the new revision, CSDA-C-101 Core Drilling explains that ownership of holes and openings rest with the owner or contracting agency, not with the cutting contractor. The CSDA contractor is typically creating the hole for another trade. Once the hole is made, the other trade requires ownership or control of the hole to utilize it for the purpose it was created. If there is a time lag between the time a hole is created and the time it is used by another trade, the owner or contracting agency needs to maintain a safe work area with fall protection, proper barricades and/or hole covers during the lag. To view and download CSDA-C-101, visit www.csda.org or call 727-577-5004 for more information.

CSDA member D-Drill Master Drillers, Ltd. of Coventry, England, was invited to the job at the planning stage. The contractor was given a specific scope of work, which involved the diamond drilling of forty 150-millimeter-diameter (5.9-inch) holes 300 millimeters deep (11.8 inches) at three separate levels up the chimney stack to accommodate the steel locating pins. The three drilling levels were spaced 15 meters (49.2 feet) apart, with eight holes being drilled on two of the levels and 32 holes to be drilled on the other. Access was naturally the first issue to be addressed on the job. D-Drill and the site owners decided that the safest and easiest option would be to lift operators up to working platforms previously installed by another contractor. This was achieved by attaching a riding basket to an on-site crane and lifting the basket with operators inside. “Our guys had to have a stomach for heights to complete this job, but assured me from the start that it would be no problem,” said Mick Brown, manager of the company’s Sheffield office. “As a company, we leave nothing to chance. Operators undertook specialist training to work at heights and there were rescue teams on standby with abseil [rappel] equipment should anything have gone wrong during the work.” Core drilling with diamond tools was the only viable option available to Tata Steel. The precise nature of this application meant that the holes had to be placed in the exact location specified without causing damage to the rest of the brickwork in the chimney stack. Once positioned in the work area and safely secured, operators began by drilling eight holes for one of the three steel bands and monitors. A Hilti DD350 core drill rig and motor was used for the creation of the 150-millimeter-diameter (5.9-inch) holes, which was specially fabricated at the client’s shop prior to the start of the work. The fabrication allowed the locking down pins to be manufactured and attached to the steel rings prior to being fitted. Core bits were supplied by the customer. After an initial setup time of one hour, each 300-millimeter-deep (11.8-inch) hole took approximately 30 minutes to drill, taking an operator one shift to complete the eight required holes on two of the levels. For the third level, where 32 holes were required, it took two shifts for all drilling to be completed. While the drilling work was relatively straightforward, the working conditions were not. Weather was a big factor during the course of the job, and several visits to the site had to be postponed due to strong winds in excess

of 25 mph. It was unsafe for operators to be working up on the chimney stack, or for anyone to be transported to or from the work platforms by the riding basket and crane during periods of high winds, so the team from D-Drill had to bide its time. When conditions were deemed safe enough to work, operators were attached to the work platform by safety harnesses. Thankfully, the emergency rescue team from Tata Steel was never called upon to rappel any injured parties down the chimney stack, and worked hard with the contractor to maintain a safe work area at all times. Several separate visits were made to the site, as per the works program, to fit in with the ongoing fabrication of the steel pins and bands by the client. In total, D-Drill operators drilled 40 holes on the chimney stack and, despite some delays, were able to complete the work as quoted. As a result of laying the framework for the successful sensor installation, the contractor has been approached by Tata Steel to perform further drilling work. “We believe both ourselves and our client completed the job in the safest possible way and both parties are pleased with the outcome,� concluded Brown.

SOCIAL MEDIA FOCUS
LinkedIn Exploits the Power of Networking By Sue Ann Kern
E
ach and every one of us will agree that networking is a powerful and critical business tool. Utilizing colleagues and coworkers to share ideas, promote products and services and make introductions to other like-minded professionals can prove to be a more costeffective means of forging new business connections and creating new opportunities than advertising or public relations. Often, an individual we meet through networking is not the person that we need to meet in order to accomplish a certain business goal. Yet, many times, that individual knows the person we need to meet, or knows a person who knows the person we need to meet. The power of networking is based on the idea of “six degrees of separation.”
4 6 | d e ce mb e r.1 2
Six degrees of separation is a concept that was developed in 1929 by Hungarian author Frigyes Karinthy, who surmised that because of technological improvements in communication and travel, the world is theoretically smaller from a social standpoint. These improvements made it easier for families, friendships and associations to span the globe, allowing humans to be connected across not just countries but across entire continents. This theory supposes that every person on Earth, through a series of a maximum of five introductions, is connected to every other person on Earth. Now, flash forward to 2012. Technology and communication improvements have indeed made the world even smaller. The six degrees of separation theory, which arguably is now closer to three or four degrees of separation,
means that we could probably meet that elusive executive at that corporation we have been targeting because one of the individuals in our network knows him, or knows someone who knows him, or knows someone who knows someone who knows him. LinkedIn takes advantage of this theory and has become the most powerful and largest professional social network on the internet since its launch in 2003. Today, LinkedIn has over 175 million members in more than 200 countries. Like most other social media sites, LinkedIn is free with an option to upgrade to various paid premium accounts. However, unlike many other social media sites, LinkedIn is intended to be a site solely for business professionals. This is not where you will find out about your friend’s weekend escapades
When you join LinkedIn, you will be prompted to create your profile, which, for all intents and purposes, is your online resume. Just like in your resume, you will provide information about your current and past positions, your education, your professional and social affiliations, hobbies and interests. You will also be asked to upload a photo, create a concise professional headline and craft an executive summary explaining who you are and why you are who you are. The most important components to complete are your professional headline, current and past positions, your contact information and your profile picture. This is because this information is what will appear when people find you through a LinkedIn search. Your professional headline (think “elevator pitch”) must be succinct since you only have 120 characters, and should contain specific and powerful keywords about your talents and specialties. This will help others to locate your profile through a search. Consider this when you are creating your headline: what keywords would you use to search for someone just like you? The remainder of your profile can be a work in progress. LinkedIn will prompt you as you are developing your profile. You will see a progress bar and frequent dialog boxes that will remind you what needs to be done to have a more complete profile. You can also add LinkedIn applications to make your profile more compelling and individual. Consider regularly updating your profile as well.
Creating Connections When you have completed most of your profile, it is time to start searching for connections. Remember that Rolodex with the thou-

or where you would post photos of your son’s football game. LinkedIn is the virtual hangout for executives from all Fortune 500 companies. Members have an average of $109,000 annual income and nearly half are the decision makers for their households. In essence, LinkedIn is the perfect social media site for business professionals who do not necessarily like social media. Like Facebook, LinkedIn can be used to promote a business and over 2 million company pages can be found on the site. However, whereas Facebook business pages are about marketing the business, the main purpose of LinkedIn is to promote yourself as an individual. Your profile is about you, and you just happen to work for a certain company. If you leave that company to work elsewhere, your LinkedIn profile still belongs to you and reflects your expertise and experiences. Simply update your LinkedIn profile with the new information.

sands of business cards? Well, that is a good place to start. Begin by searching for colleagues, coworkers and college friends. When you find them, click on “Connect” to send them a request to connect. LinkedIn will require you to specify how you know the individual. Have you worked with them? Did you go to school with them? Were they your client? If you specify that they are your friend, you will be prompted for their email address. Never, under any circumstance, choose “I Don’t Know…” This is to prevent spam, and if done repeatedly can cause your account to be suspended.
10/18/12 2:05 PM
As you build you connections, you will find that you will start receiving invitations to connect with others. Some will be people you know, others will not. It is up to you whether or not you want to connect. Many of you will be eager to get as many connections as possible, because the number of connections you have shows up on your profile and can look impressive. Others of you may want to connect only when it makes sense. Bigger is not necessarily better. Just remember the concept of six degrees of separation, which tells us that it isn’t necessarily who you know, but who the person you know knows.
c o n c ret e o p en i n g s | 4 7
social media focus Referrals When you send your resume to a prospective employer, you would not dream of leaving out referrals. Likewise for LinkedIn, which has a powerful tool that allows you to ask any of your connections to write a referral for you. This referral can then be showcased on your profile. Do not be afraid to ask for a referral. Also, be generous with referrals to your connections. You do not have to wait to be asked. Anyone would appreciate an unsolicited compliment and would most likely be willing to reciprocate.
Groups The Groups setup is arguably the powerhouse tool of LinkedIn. There are nearly 1.2 Million groups, spanning interests from accounting and astrology to zodiac signs and zoology. Search for and join groups that are of interest to you, and then dig in by sharing relevant content on discussions or by starting a discussion yourself. Groups are an excellent way to showcase your knowledge and brand yourself as an expert in your field. Consider creating your own group. Groups also allow you to reach out beyond your connections and network with others in your industry and those with whom you who have shared interests. Again, this allows the six degrees of separation principle to help you associate with more people and shrink your virtual world.
Hiring Solutions Whether you are looking for a job or looking to hire someone, LinkedIn is a valuable resource and effective tool. Nearly 85% of the Fortune 100 companies use LinkedIn to search for potential candidates to fill open
positions, to verify their resume and referrals, and to reach out to the individuals. LinkedIn will even create a traditional resume from your profile with the click of a button, although many human resource departments prefer utilizing your online profile over the old fashioned paper version. If you are job hunting, search LinkedIn Companies to see what job openings are posted. Utilize your connections and the six degrees concept to see how you can connect with influential individuals at those companies. In this situation, you may want to consider a premium account, which will give you more access and information about companies and individuals above and beyond the standard account. Take advantage of Groups to showcase your expertise and elevate your visibility.
Budgeting Your Time on LinkedIn Like any social media site, internet site, smart phone application, television show, hobby, sport or friend, LinkedIn can consume a lot of time. It is important to budget your time and not allow yourself to get sucked in. Consider the acronym CRISP: Check LinkedIn a few times a week Respond to comments from connections Inform your connections Search for new connections Peruse other sources for interesting information Plan on spending no more than 10-15 minutes, 2-4 times a week on LinkedIn. That is much less time than you would spend at a live networking event. Respond if someone has sent you a message or contributed to any Group discussions you have participated in. Share an update, create a discussion or comment on the status updates and discus-

OSHA/CSDA Alliance Latest The Alliance between the Concrete Sawing & Drilling Association (CSDA) and the Occupational Safety and Health Administration (OSHA) is now in its seventh year and continues to educate contractors, prevent on-the-job accidents and injuries and provide vital materials to advance a safe work environment for sawing and drilling professionals. Here is the latest news from the Alliance Program.
Fatal Occupational Injuries Down Results from the Bureau of Labor Statistics’ National Census of Fatal Occupational Injuries were released in September. Findings show that the number of fatal work injuries in 2011 was slightly lower than final results from 2010. Last year, 4,609 workers died from work-related injuries, down from a final count of 4,690 in 2010. “It’s a step in the right direction, but more needs to be done. We will continue to collaborate with employers, workers, labor leaders and safety and health professionals to ensure that every American who clocks in for a shift can make it home safe and sound at the end of the day,” said Secretary of Labor Hilda L. Solis.
More Best Practice Documents Released in Spanish OSHA and CSDA are pleased to announce that a further two Best Practices produced by the Alliance have been translated into Spanish. The two documents— CSDA-OBP-1004 Electrical Safety and CSDA-OBP-1005 Scaffold Safety—were released in September and are available to download from the CSDA Website. They are the fifth and sixth Best Practice documents to be translated, with more Spanish translations planned for the future.
OSHA/CSDA Alliance at World of Concrete 2013 Federal and local representatives from OSHA will be at CSDA booth #C4441 during the World of Concrete trade show and exhibition in Las Vegas on February 5-8, 2013. The OSHA representatives will be on-hand to provide advice and guidance, while Board and committee members, and contractors from CSDA will be present to share information about the industry, the association and discuss the benefits of being part of an Alliance program. For more information about the OSHA/CSDA Alliance program, or to view documents released by this partnership, visit www.csda.org and click on the “OSHA Alliance” link under “Safety” or call 727-577-5004.

MEMBER TESTIMONIAL
• Presentations • Roundtable discussions • The Tech Fair
After thirty years of surveying management in construction and highway building, I decided that I wanted a change in careers. I was introduced to Ground Penetrating Radar (GPR) and became intrigued with the technology. My research into GPR led me to training classes in Oregon. I returned home to develop my own business strategies for my new company; Subsurface Imaging Solutions GPR (SIS GPR). The first place that I turned to was the Concrete Sawing and Drilling Association (CSDA), because I learned in training that GPR and concrete were a perfect fit. I decided to join Rob Black CSDA and, fortunately, I joined the week before the association’s Summer Meetings in Atlanta and was encouraged to participate. While there, I was hosted at various venues and met with all kinds of concrete sawing and drilling business owners. The meeting in Atlanta was the perfect place for me to gather more information about how to proceed in the growth of my business and my enthusiasm for GPR. I am grateful for the hospitality of the CSDA folk, and for a feeling of inclusion from the first phone call to being asked to contribute to this column. I know that my experiences at the CSDA meetings in Atlanta will enable me to build a strong successful business in Ground Penetrating Radar.

Member Benefit Programs
Networking at the Annual Convention and Quarterly Meetings
The Concrete Sawing & Drilling Association negotiates member benefit programs with national vendors in order to provide cost-savings opportunities for CSDA Members.
The number one benefit for members has always been the opportunity to network with cutting professionals at the annual convention and quarterly meetings. This networking provides opportunities to forge new relationships and learn from other experienced professionals.
CSDA Training and Certification Programs Over 2,000 members have graduated from more than 20 classroom, hands-on and online training programs: Cutting Edge, Slab Sawing & Drilling, Wall Sawing, Wire Sawing, Operator Certification, OSHA Construction Safety and Estimating. CSDA offers online training at www. csdatraining.com for those not able to afford the time or the money to send operators to remote classes. The CSDA Company Certification 3-tier audit program has been developed to provide owners, architects, engineers, general contractors and government officials with a valuable prequalification tool, to qualify that hiring a certified company will ensure a demonstrated capability from a sawing and drilling professional.
CSDA Safety Resources and Toolbox Safety Tips (TSTs) The 230-page CSDA Safety Manual, CSDA 57-page Safety Handbook and five safety DVDs are designed specifically for concrete cutters and are available to members at a significant discount. TSTs can be used in employee safety meetings and can be an important part of your company’s safety program. CSDA has released a total of 100 TSTs since the program began. A new TST is released every month.

CSDA Training Firsts
Patrick o’brien Executive Director
T
he Concrete Sawing and Drilling Association (CSDA) is introducing two firsts at the February 5-8, 2013 World of Concrete (WOC) in Las Vegas, Nevada. As a cosponsor association, this event is the most important exhibition of the year and a perfect opportunity to introduce new training classes. The first ever CSDA Concrete Polishing class will be held at WOC, while one of the popular CSDA Operator Certification classes will also be offered for the first time during the Las Vegas show. To complete the training lineup, CSDA will again offer its Estimating class. Graduates of these training classes will join the 3,500 existing graduates of CSDA training courses, showing a dedication to increasing their knowledge and demonstrating their professionalism to the industry. Polished concrete floors continue to grow in popularity and the number of traditional CSDA contractors adding floor polishing and preparation services to their businesses is increasing. The CSDA Concrete Polishing class is a two-day classroom and hands-on course that focuses on the correct setup, operation and maintenance of equipment, the differences between wet and dry polishing as well as how to accurately bid polishing jobs. The goal is to give students a model for producing floors to a consistent high level of quality, regardless of the type of concrete. The educational training focus for WOC is shifting to certification courses, allowing attendees to earn credit while attending this annual exhibition. CSDA has traditionally offered classes for new operators looking for
7 2 | d e ce mb e r.1 2
training in the fundamentals of sawing and drilling. However, in acknowledgment of the WOC trend and in response to member requests, CSDA will offer its first certification course—Core Drilling 201—at the show. This class is for experienced operators who want to gain the highest level of proficiency in the core drilling discipline. Content will be split between classroom and hands-on slab instruction, with students spending time at the outdoor exhibit booths of CSDA member companies to perform practical exercises. The third training class offered by CSDA is Estimating, a class that quickly filled when it was introduced to the WOC Educational Program in 2012. This class focuses specifically on the practice of estimating sawing and drilling jobs and is taught by industry experts with real-world experience. The association anticipates a similar response rate for the WOC 2013 class as this past year. Training will play a key role to the future success of the sawing and drilling industry. CSDA is committed to providing contractors with training program offerings in a variety of formats and locations to meet the needs of its members. In addition to the WOC classes, CSDA offers regional training classes, classes at its St. Petersburg College training center and online training. I encourage you to visit one of the outdoor training classes and see for yourself the level of quality on display. Stop by CSDA booth #C4441 for a schedule of the training classes and consider signing up for one in the future.

Husqvarna’s extensive line of wall saws ensures there is a saw to meet your needs. Wall sawing involves a lot of preparation; Husqvarna makes equipment easy to transport and quick to assemble at the site. Every detail is carefully planned and designed to ensure efficient operation. Husqvarna’s line of high frequency electric wall saws includes the WS 482 HF and the WS 440 HF. The WS 482 HF wall saw boasts more power, larger blade size capacity (62") and offers the best powerto-weight ratio on the market. The saw is operated by radio remote control, which allows total control of the sawing process and freedom to move around the workplace. The WS 440 HF wall saw features a powerful, water-cooled electric motor that supplies constant high power to the spindle over a wide rpm range for faster and more efficient sawing. The motor generates 17 hp to the shaft, despite the fact that the saw only weighs 55 pounds. Husqvarna’s WS 460 hydraulic wall saw is built on a modular system where the weight is evenly distributed, making the saw easy to transport, handle and set-up. The two-speed hydraulic motor provides optimal speed depending on material, blade diameter and type of blade.
