pipe dream Not Just a

Diamond Wire Saw Cuts with Speed and Precision


pon discovering that a giant section of piping was too long to connect to a new stack at a West Virginia power station in April 2009, the general contractor at Fort Martin

Power Station needed someone to modify the pipe, and quickly. When CSDA cutting contractor Accurate Pro-Cut, of Parkersburg, West Virginia, was approached to cut the pipe to the required specifications, they knew of an ideal way to make this cut, with great precision and in only a few days. Fort Martin Power Station is owned and operated by Allegheny Energy Supply Company, a subsidiary of electricity utility Allegheny Energy. The power station has a generating capacity of 1,107 megawatts of electricity and is located in Maidsville, West Virginia. The generating facility operates 24 hours a day, using coal to generate electricity and deliver low-cost, reliable electric service to over 1.5 million customers in Pennsylvania, West Virginia, Maryland and Virginia. In order to turn coal into kilowatts, the coal must be placed into a grinder to produce a fine powder. This powder is then blown into Fort Martin Power Station, Maidsville, West Virginia.

a furnace area inside a large boiler, where the coal burns much like a gas. Purified water is circulated through steel tubing inside the boiler, which can be as tall as a 23-story building, and the intense heat of the furnace—approximately 1,000 degrees Fahrenheit—boils the water and turns it to steam. The steam is then piped at high pressures, around 3,600 psi, to a turbine, where it spins giant, fan-like blades connected to a

core drilling 1,440 holes through the flanges of the pipe readying it for the connection,” said Nick Ledford, site supervisor for Accurate Pro-Cut, “we were in the right place at the right time to help Washington over their next hurdle. Our good working relationship with them probably did not hurt either,” he added. Hand sawing the pipe was considered, but with time and precision being extremely important factors, it was much more feasible to employ wire sawing. The general contractor had also considered the construction of a replacement pipe, but the time and associated costs involved with this alternative were far more expensive than having the existing pipe shortened. Accurate’s plan was to perform two cuts to shorten the pipe to the desired length so that it would fit into the stack. Accurate had to set up its wire saw equipment on and around the pipe, working at approximately 165 feet in the air. Any breaks in the wire or any adjustments that would have to be made would require the team to navigate across a 10-foot-wide I-beam to gain access to the work area. Only one wire saw setup was required, so the cutting team did not have to worry about moving the saw during the course of the project. Special care was taken to make sure the operators were tied off at all times to prevent falls.

A new stack was being installed to continue production of coal-powered electricity at the plant.

The wire sawing setup consisted of a Diamond Products WS25 wire saw, CBN65 hydraulic power unit and 10-millimeter-diameter electroplated wire. It was believed that 100 feet of wire would be sufficient to perform the cuts. Roller wheels were removed and mounted to a 12-inch I-beam with 0.5-inch bolts, c-clamps and ratchet straps for added security. The operators wrapped the wire around the pipe at the cut line using no additional wheels or brackets, and ran the wire counter clockwise, pulling the wire in their direction. It took a 10-hour day to complete the first cut. On completion of the first cut, operators discovered that the lack of water had caused excessive wear to the wire and the diamonds, so an additional 100 feet was shipped to site to be ready for the next day of cutting. Equipped with additional diamond wire, the cutting team returned on the second day of the project to complete the second cut and demobilize. This time, the cutting and dismantling of the equipment took just eight hours. The remaining section of the pipe was secured in place with an existing frame and bolts. Accurate did not go completely without water on the job site. The team had to deal with rain and high winds on their work platform at 165 feet, so took extra care to be properly tied off to prevent falls. The elements and the predetermined water restrictions were not the only challenges encountered by the Accurate operators. The material being cut was fiberglass, not concrete. The dust and Diamond wire sawing was the ideal application for this project, requiring two days of cutting.

THE PROFESSIONAL’S CHOICE When I’m up against a tough job I can depend on the DITEQ team for their quality products and their expertise. Our job was to cut a doorway through the wall of this turn of the century bank vault. The wall was 24” thick concrete reinforced with 3/4” square double mat rebar. After coming out to the job, the DITEQ folks recommended the combination of the Auto Feed, SHIBUYA TS-403 Stitch Drill and ARIX C-52 double pointed core bit. That combo worked like a dream. We got thru the concrete and rebar in no time and were finished well before our scheduled deadline.

eople often associate vaults with banks. They imagine vaults filled with piles of bank notes or stacks of gold bullion. In this instance, however, “The Vault” is the name given to a 28,000 square-foot luxury warehouse and exclusive entertainment center in Denver, Colorado that has been converted from an existing, heavily-armored building. Some of the more interesting features of The Vault include an

exotic/antique car showroom and storage area, wine vault, cigar humidor, shooting range and gun vault, simulated golf driving range, game hall with pool and poker tables, video arcade and archery range. Also planned is a workout room and shower, bar and lounge, a DJ booth and dance floor, dining area and full service catering kitchen. The warehouse is located within two miles of downtown Denver and close to Invesco Field and the Pepsi Center and it is hoped that The Vault might become a destination, high-energy night club, in its own right, when completed. In order to accommodate the proposed bar and lounge areas, two concrete slabs of 6-inch-thick suspended ceiling had to be removed to raise the ceiling. One slab measured 12 feet by 12 feet and the second measured 14 feet by 15 feet. The combined weight of the slabs was 11,000 pounds. The general contractor, Vintage Builders of Boulder, Colorado, enlisted the help of CSDA member DeAndrea Coring & Sawing, Inc., to perform the necessary cutting work. “We have acquired a reputation for being able to handle specialized cutting and coring projects and were excited to be a part of this one.” said Rich Gneiser, field supervisor for DeAndrea. DeAndrea faced several constraints on this project. The ceiling

slab was part of a mezzanine that had an existing wooden sub-floor above it which the general contractor did not want to remove, as it had been earmarked for later use in the renovation. In addition, on the sides of the ceiling slab were block walls which allowed for only 6 inches of access for both operators and equipment upon completion of the cuts. This proved to be very limited access. Last, workers had to perform their tasks while making sure not to scratch the $100,000 vault door that was in the room. One of the most challenging aspects of this project was the positioning of the wall saw as it had to be mounted upside-down from the slab ceiling. As always, the correct and safe mounting of the sawing

equipment was critical, but the angle and force of gravity, coupled with the tight cutting area made this process all the more difficult. DeAndrea used 0.5-inch drop-in anchors, 4 inches deep into the slabs, to secure the saw. DeAndrea’s other main challenge was the picking of the 11,000pound sections of concrete without pinches between the slab or the chains, and the secure lowering of these sections. The restriction of space and maneuverability in the work area was also a hindrance to the team, and the length of time taken to lower and remove the cut concrete slabs was prolonged as the entire room had to be cleared of all equipment and personnel before proceeding. However, a detailed plan for the cutting and removal of the ceiling slabs was developed and reviewed by all workers to insure the safe cutting and removal of these massive slabs. The first task on this project was to measure and remove sections of the wooden sub-floor in order to core drill the required picking holes from above the suspended slab ceiling. This was the only area of wood floor that was cut. Next, the two concrete slabs were shored up in preparation for the cuts. Operators then wall sawed the perimeter of the sections, 6 inches in from the walls. The cutting of each slab took two, 8-hour shifts to complete and consisted of four cuts. The next stage of the project involved a 90-ton crane, which was employed for the picking and removing of the concrete sections. The crane was positioned on the exterior of the building, requiring a lane of traffic to be closed. Everyone involved in the lifting and lowering process attended a one-hour safety meeting to clarify all aspects of this part of

Roundtable Discussions Get People Talking he business world is constantly looking for new ways for people to meet, interact and discuss pertinent topics. From the traditional business meeting to telephone conference calls, brainstorming sessions and more recently, web-based meetings via webcam, there is a continuing need to have people discuss views and ideas. One format that has proven to be successful for members of the Concrete Sawing & Drilling Association (CSDA) in this quest is the roundtable. This type of setup allows all participants the opportunity to express their ideas and opinions in a structured, yet informal manner. A roundtable discussion format is ideal for those who may not usually speak up during meetings but who may feel as though they have worthwhile points to make. The layout of a traditional board room meeting can often be quite intimidating, whereas a roundtable layout can provide a much more informal atmosphere for participants. The chance to sit with peers and discuss a series of topics informally can provide those who often remain silent with a newfound confidence. Meanwhile, roundtables are overseen and moderated in order to keep discussions on topic and moderators can help provide guidance if needed. For those who are unfamiliar with the idea of a roundtable discussion, the format is relatively simple. Participants sit at a table and discuss a series of predetermined 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.

1 4 | sSEPTE e pte mb MB er.09 ER .09

CSDA has found that roundtables are a great way of gleaning information from members and non-members alike. The sharing of knowledge and ideas has proven to be invaluable for all involved. One CSDA member who has experienced the benefits of roundtable discussions is Morgan Steiner of Viking Concrete Cutting, Inc. of Klamath Falls, Oregon. In 1994, Steiner moved his concrete sawing business from Southern California to Southern Oregon, an area east of the Cascade mountain range, with an elevation of over 4,000 feet. One of the biggest changes he encountered was the change in climate and the effects this change had on his operators, equipment and cutting operations. Operating concrete cutting and coring equipment in a geographic area that experiences below-freezing temperatures, several months of the year, has many challenges. Relocating any company is a challenge, but relocating one to a different climate is another matter. Steiner attended a CSDA roundtable, and during the discussions learned a great deal from other contractors. More importantly, he found an opportunity to meet people in the industry who have firsthand knowledge about the challenges faced while cutting concrete in cold climates. In talking to fellow contractors from areas like New Jersey, Chicago and Canada, Steiner was able to get a lot of ideas about sawing in a cold environment. Tips included parking trucks inside in warmer garages, draining

water from equipment, rolling and storing hoses in cabs of vehicles and bypassing water systems in saws. Steiner was also given useful information on employee comfort and safety, and how to deal with the changeable weather conditions while traveling to and from the job site. “To be able to talk to people who are in this industry and to exchange ideas with them was incredibly beneficial to me, and helped me greatly when I moved the company,” said Steiner. CSDA has held three roundtables during 2009. Discussions on the topics of slurry recycling, risk management and different methods of billing cutting services attracted many CSDA members and other industry professionals keen to learn more about those subjects and the discussions were quite in-depth. The proceedings from all three roundtables have been transcribed and are available for review, another benefit of being part of the association and actively taking part in these events. “Roundtables provide attendees with a great format to share information and learn from the knowledge and experiences of others,” said CSDA executive director Pat O’Brien. “The association is extremely pleased with both the attendance and outcomes of these discussions,” he added. 2009 CSDA Roundtables Sustainable green building construction is a very hot subject. The purpose of the Slurry Recycling roundtable was to share collective experiences on the topics of concrete slurry containment and recycling, including individual state regulations; knowledge of acceptable pH levels for waste materials; the understanding of what constitutes a Spill Prevention Control

and Countermeasure (SPCC) and the implementation of a Storm Water Pollution Prevention Plan (SWPPP). The general response from participants suggests that the control and safe disposal of slurry and other waste materials can be handled in differing ways depending on the individual regulations enforced by each state in the U.S. or governing body. Several states have imposed tight regulations with expensive fines for those contractors who do not adhere to them. However, the environmentally-safe disposal of slurry and other waste materials is not as strict in other states, but contractors in more looselyregulated states are bracing themselves for similar levels of control in the near future. For those who are already under tight state regulations, the containment, transportation and disposal of slurry is an expensive, but necessary, part of the work routine. Many feel that before too long there will be nationwide regulations in place, requiring compliance from all companies in the sawing and drilling industry.

w w w. CS DA. ORG

Several contractors within CSDA have been working with companies to separate and reuse water mixed with slurry, saving on water consumption and reducing the amount of waste material produced. Other companies provide the means to return alkaline-rich slurry water to a neutral pH 7 so that it can be disposed of safely, another important factor that governing agencies like the Environmental Protection Agency are keen to enforce. The requirements for documentation such as SPCC or SWPPP were also discussed, and some attendees told of their experiences of being fined for not having such a plan in place on the job site. The sharing of this kind of information with fellow industry professionals, about the positive or negative aspects of various kinds of regulations, greatly enhances the value of participation in roundtables. Discussions during the Risk Management roundtable focused on issues like hiring requirements, training of employees and attitudes toward insurance claims, with emphasis on the promotion of positive attitudes towards all aspects of safety.

Embracing risk management strategies will result in long-term claim cost reductions of companies by incorporating industry-specific loss-reduction techniques in conjunction with aggressive claims management procedures. Contractors discussed how their approach to risk begins during the hiring process with procedures that require physical exams, drug screenings, driver’s license reviews and employment history checks. Some employers use third-party contractors to carry out a series of background checks on a potential employee. All agreed that ensuring the right person is chosen to fill a position is paramount to instilling a good sense of safety in the workplace. In addition, in order to maintain a safe working environment, some contractors have put incentives in place so that operators adhere to safety guidelines and avoid accidents and injuries. Others take advantage of the Toolbox Safety Tips, provided by CSDA, to educate operators and to keep them ever vigilant of potential hazards. The issue of insurance claims brought about some lively debate, and elicited many

anecdotes about how certain situations can quickly escalate and greatly affect a company’s bottom line. Contractors felt that stressing the importance of an operator’s health and well-being is an excellent way of showing employees how valued they are. Hopefully, this leads to a mutual respect between employer and employee, a relationship that can be critical if an employee files a medical claim. Another recurring theme was training and the importance of having a structured training program to ensure a high level of operator safety. Contractors explained how participation in the CSDA training program has proven to be an excellent way of achieving a high level of safety throughout a company. “If you have the CSDA certification process in place, where your employees go through 101 and 201 levels of training and then achieve certification, that really makes an impression,” said Susan Hollingsworth of Holes Incorporated. “It’s not you saying your operators are qualified. It’s a professional body saying that they have addressed operational issues, they’ve addressed safety, they’ve addressed proper equipment usage. And your operator has participated in training and has the knowledge to go forward.” A roundtable entitled Different Methods of Billing Cutting Services was held to discuss how cutting contractors handle billing. Participants offered ideas and opinions on issues such as the pros and cons of various billing methods, how quotes are broken down to show job-specific requirements and how the introduction of online billing has affected business. This roundtable provided an insight into how estimators approach their jobs and what methods work best for developing estimates depending on the size and complexity of the cutting work. Moderators asked participants to look at how they are currently billing work and determine whether that method is the best suited for producing an accurate cost breakdown for the work being bid. Contractors agreed that a strong focus on accuracy, serious attention to detail, foresight of potential additional costs and a high degree of openness and honesty with the client are traits of good

estimators. Whether basing an estimate on a fixed, lump sum, unit, cost-plus or hourly price, an estimator should consider all of these factors to ensure the bid is developed correctly. Online billing was a topic that received mixed reviews. While some contractors have embraced the idea of online invoicing and billing, others still feel that the tangibility or reliability associated with physically having the paperwork in-hand is not ready to be replaced yet. However, all were in agreement that the speed and increased ease of dealing with electronic payments could not be ignored. “Anything that gets paid faster, quicker, we’ll take it. If somebody wants to pay with a credit card, great, but anything that speeds up the invoicing, billing and collection process is a good thing, because sometimes time spent on those activities are just a waste,” said Jeremy Martin of Hilti. Roundtable discussions provide something that other types of meetings or formal documents cannot—real life

Participants can choose to enter into the discussions or sit still and listen but either way, they get the opportunity to hear what their peers think about given subjects.

IACDS Annual Meeting Diamond Cutters Gather for the International Association’s 14th Anniversary


he 2009 annual meeting for the International Association of Concrete Drillers and Sawers (IACDS) was held June 4–6 in Dublin, Ireland. The international association is now in its fifteenth year, and continues to be a fantastic way for national associations to meet and share their combined knowledge of the industry, while learning new ways to continue their growth and prosperity. The 2009 meeting was no different.

In attendance were 31 representatives from Austria, Belgium, Bulgaria, Germany, Hong Kong, Ireland, Japan, Liechtenstein, Russia, Spain, Sweden, Switzerland, the United Kingdom and the United States. Included in this number was Boyko Tomov of Enemona SA, a new representative from Bulgaria. The goal is to eventually have a Bulgarian association in place to represent concrete cutting contractors from the country. Encouragement can be taken from the progress made by other national associations like AEDT of Spain, which was

in the same position just a few years ago. Two technical presentations were made by CSDA lead trainer, Rick Norland. The first presentation Ground Penetrating Radar (GPR): Real Time Non-Destructive Testing was of particular interest to the Europeans, as this technology has not been available for them to use and expand their businesses. The second presentation Advanced Wire Sawing Methods was also very well received and provided great insight. A portion of the meeting was held at the Diamond Innovations saw diamond manufacturing

plant in Clonshaugh, Dublin. IACDS members received a plant tour and market presentation as part of their visit. The Diamond Award competition continues to be popular with cutting contractors, and the 2009 award ceremony— held in Las Vegas during World of Concrete—was attended by healthy numbers of press and the general public. The next competition will open in 2010 so contractors from all corners of the globe should be ready to document and photograph their most unique and challenging jobs over the next year to have a chance of winning. During the meeting, IACDS continued discussions as to how it can allow representatives without a formal national association to play a more active leadership role in the international association. In connection with this development, representatives are formalizing the election process to have delegates prepare their suggestions for future leaders of IACDS in advance of the meeting. Marketing of IACDS around the globe also continues to be a focal point for members. Advancements have been made with the website while the campaign to keep trade publications advised of IACDS events and accomplishments remains strong. The chosen venue of Dublin, Ireland, was quite fitting, as it marked the end of the second term for the current IACDS president, Patrick O’Brien. “It has been my pleasure to serve as president. The association can be proud of the achievements that have been recorded, as they have helped move the international representation of concrete cutting contractors to the next level,” he said. O’Brien will now make way for the incoming president, Peter White of the U.K. Drilling and Sawing Association. Elected as vice presidents were Jose Blanco of Spain and Norikazu Shibuya of Japan. Representatives from each country presented a series of financial reports and summaries for their respective associations, with many associations presently suffering as

a result of the difficult economic conditions. It was noted that Germany currently has the most contractor members with 532. Those contractors who join the German association can reduce the social tariff levied by the government and this fact has contributed

to strong membership growth. It was also reported that diamond tool production in Japan is down 51%, a trend that will hopefully reverse as signs of economic recovery emerge. Since its inception in 1995, IACDS has taken great strides to advance the industry throughout the world. Technical documents have been produced providing extremely useful information on Basic Parameters for Concrete Drilling and Sawing Equipment and Tolerances and Limits for Construction Sawing and Drilling that can assist concrete cutters in their day-to-day work. Both of these documents can be found on the IACDS website (, in the CSDA Resource Guide, mailed with the June issue of Concrete Openings, or via the Members section of the CSDA website ( These

documents are also available to members of other national associations in electronic and/ or paper copies. Other programs that IACDS has launched are now becoming more recognized in the international community. The project to collect worldwide market data for sawing and drilling contractors continues to improve each year with data coming from more countries and more credible market data being submitted. Plus, the results showing over 10,000 worldwide contracting firms is being requested and utilized by trade publications and manufacturers. An emerging project for IACDS is a formal program to educate specifiers at university level about the benefits and capabilities of sawing and drilling. In addition, the association is investigating the establishment of insurance coverage for sawing and drilling contractors. The next IACDS meeting will be held in Austria in conjunction with the April 1925, 2010 Bauma exhibition in Munich, Germany. Discussion was held about a follow-up to this year’s GPR presentation at the meeting, with demonstrations from manufacturers, followed by a full day meeting on Monday, April 26 in Salzburg. For more information, visit The International Association of Concrete Drillers & Sawers is an international trade association of sawing and drilling associations from the concrete construction and renovation industry. Its mission is to provide an international union and cooperation of trade associations to support and promote professional development of professional sawing and drilling contractors and their methods. This umbrella organization of sawing and drilling associations formed in 1995 is composed of the associations from Australia, Austria, Germany, Japan, Spain, Sweden, Switzerland, the United Kingdom and the United States.

CSDA Member Dismantles Nuclear Power Plant Site

n April 8, 2005, the Bulgarian Council of Ministers approved the construction of two 1,000-megawatt nuclear power units with pressurized water reactors at a site located near the town of Belene, Bulgaria. Following this decision the National Electric Company (NEK) began a selection procedure for contractors to participate in the engineering, construction and commissioning of Belene Nuclear Power Plant units 1 and 2, in compliance with the Public Procurement Act. On November 29, 2006, NEK signed an agreement with the Russian company Atomstroyexport to take up the role of general contractor.

CSDA member Enemona SA of Kozloduy, Bulgaria, was approached by the general contractor to carry out 10% of the cutting and demolition work. Boyko Tomov, vice director of marketing and development says, “We were selected by Atomstroyexport as a subcontractor for this project because of our equipment base and our experienced and skilled operators.” Tomov continued, “The company has done many projects for the general contractor at the Kozloduy Nuclear Power Plant, and has a reputation for being both efficient and reliable.” Enemona signed a contract with Atomstroyexport in 2008 to perform some of the dismantling work. So far, the completed activities have included the dismantling of heavy reinforced concrete; dismantling of

Wooden troughs were also placed over the cuts, to limit water loss and help the cooling of the wire. The provision and use of required personal protective equipment like hard hats, belts, shoes and eye and ear protection was closely monitored. A range of equipment was used at the Belene site, including Tyrolit-SB and Hilti DS-WS 15 saws and Hilti-DD 200, 250, 350 and 500 core drills. Other hammers, wedges and crabs for breaking and cutting of the concrete and reinforcement were also used.

The Business of Business

Safety: The Universal Language? Literacy and Language Challenges in the Workplace By Mark A. Lies II and Elizabeth Leifel Ash


s the American “melting pot” becomes increasingly diversified, employers face inevitable issues related to language in the workplace. Employers can no longer assume that qualified

workers speak or write English. Employers who hire workers that do not speak English are obligated to ensure that all employees, regardless of their linguistic background, receive and comprehend safety-related training. For employers whose supervisors only speak English, the requirements set by the Occupational Safety and Health Administration (OSHA) can present unique challenges. This article outlines OSHA’s policies with respect to training non-English-speaking employees, and offers recommendations for employers in assuring that all employees are adequately trained to work safely.

OSHA’s Training Requirements Numerous OSHA standards, from lockout/tagout to forklift operation and bloodborne pathogens to hazard communication, require employers to train or instruct employees in some way. OSHA generally treats its training requirements as performance-based, meaning that OSHA defers to each individual employer to fashion the most effective manner to accomplish the goal of the standard. For that reason, none of OSHA’s training standards require employers to use particular documents, teaching methods or language to train employees. Instead, OSHA requires employers to present information in a manner that employees are capable of understanding. For example, if an employee is not literate, the employer does not satisfy OSHA training requirements merely by telling the employee to read training materials or review safety programs. Likewise, if an employee does not speak, read or understand English, training must be provided in a language the employee understands. OSHA has tasked each of its inspectors with the duty to determine whether the training provided by an employer satisfies the intent of the Standard—whether employees receiving the training have actually understood the content. Obviously, this is a highly subjective exercise. One way that an OSHA inspector will make this evaluation is to interview employees. These interviews may or may not take place in the presence of a management representative. Many OSHA inspectors are bilingual, speaking both in English and Spanish, and those who are not may request another employee to act as an interpreter to translate during

2 6 | SEPTE MB ER .09

an employee interview. Translation issues can present potential bias problems during employee interviews, whether the interpreter is another employee, a management representative or an OSHA official. For this reason, employers must ensure that employees understand their right to have a management representative present during the interview. Employers may also consider requesting that a neutral thirdparty act as interpreter during the employee interview, particularly if the interview is critical and accuracy is an important consideration. Another way OSHA inspectors will evaluate the employer’s compliance with safety training standards is by determining how the

employer communicates other workplace rules and policies to employees, particularly job instructions and other non-safety policies or procedures.

The Pian Telessio Dam, Piedmont, Italy.

Cutter Uses Diamond Wire to Prevent Concrete Decay Destroying Dam


n the Gran Paradiso National Park, situated in Piedmont, Italy, stands the Pian Telessio Dam. The dam was built between 1951 and 1956 as part of the hydroelectric development of the Orco Valley. The concrete structure, of a gravity arch design, is owned by the Energy Company of Turin, and is located 1,919 meters (6,296 feet) above sea level. The dam stands at a height of 80 meters (262 feet) with a crown of 515 meters (1,690 feet), and creates a seasonal reservoir of approximately 22 million cubic meters (29 million cubic yards) of water. During its first 20 years of service, the behavior of the dam was

Did You Know? Dam Construction Arch Dam

Since the first large-scale dam was built in Egypt more than 5,000 years ago, engineers have devised various types of dams to withstand the forces of a raging river. The are five main types of bridges around the world and all have their strengths—literally speaking.

Gravity Dams A gravity dam is a massive dam consisting of thick, vertical walls of concrete built across relatively narrow river valleys. Gravity dams resist the thrust of the water entirely by their own weight. Most gravity dams like the Grand Coulee Dam in Washington are expensive to build because they require so much concrete, earth and rock fill.

Arch-Gravity Dams The Hoover Dam in the United States is an example of an arch-gravity dam. Arch-gravity dams incorporate the arch dam’s curved design that is so effective in deflecting the water in narrow, rocky locations where the canyon’s side of hard rock forces that water down into a narrow channel. The curved design also effectively holds back the water in a reservoir requiring a lesser amount of construction material. The arch-gravity dam also incorporates enough size and thickness to provide superior strength. The archgravity dam, combining the load-resisting qualities of both arch and gravity type dams, inspires the most confidence in the public at large because of its appearance of massive permanence. 3 4 | SEPTE MB ER .09

compressive load of the concrete is not exceeded) spalling stops, provided the load on the concrete does not change. This load will change when the top cut is completed and the weight of the opening is placed on the wedge. Ultimately, all operators should be aware that a concrete piece held in place by wedges is never secure and can move at any time. The only way to secure an opening is to strap it in place. Another common misconception is that a 10-inch-thick, or greater, wall opening cannot tip out. This idea has been around for a long time and is based on sound geometric conditions. Geometry shows that there is not enough room between the concrete surrounding an opening as a result of saw kerf, and the concrete of the opening to pivot on a bottom edge and tip out. This is true, as long as the pivot edge of the opening does not spall; the outside top edge of the opening does not spall; the top inside edge of the opening does not spall; or that the opening does not shift in or out and stays perfectly parallel and in line with the remainder of the wall. Assuming that the aforementioned conditions do not occur, the opening, when pivoting about a bottom edge, will jam at the top of the opening cut after pivoting approximately 3 degrees, causing the top edge of the opening to be about 4 inches out of the cut. However, the weight of the opening is now being supported by the bottom edge of the opening, and the top edge of the opening opposite from the bottom pivot edge. For the wall opening to completely tip out, the bottom edge or opposite top edge must either spall or move either

or, as a worst case scenario, a whole component part can be ejected and cause serious injury or death without the implementation of these safety measures.

Ensure Bottom Guard Flap Attachment Of equal importance to the side cover, yet often overlooked, is the bottom, rubber guard flap. This is also known as the “mud flap.” This flap is essential to operator safety, particularly in any application of floor cutting. In a floor cutting scenario, the operator’s shins and lower torso are more exposed, and are at greater risk of being struck by debris or a broken chain. The guard flap is designed to minimize this hazard, and

has been carried out intentionally.

Hydraulic Inputs Most professional concrete cutting contractors utilize high flow power supply units as their source of hydraulic power. Whether the power source is a tow-behind or truck-mounted unit, these hydraulic power supplies typically output in excess of 20 gallons per minute (gpm), with some reaching as much as 30 gpm. When switching from a high flow tool, such as a 25-gpm wall saw, it is extremely important that the operator adjust the source flow rate to match the recommended tool input. Providing too much hydraulic flow will cause motor shaft


The James R-Meter MK III & Mini R-Meter Professionals Know Before They Start

over-speeding. Hydraulic pressure is also an important factor in the settings. Overpressurization will stress all connections, hoses, seals and o-rings for the entire hydraulic circuit. Exceeding pressure inputs will typically blow out seals and o-rings at an accelerated rate, and will result in spills, leaks, downtime and costly rebuilds. Random field inspections of proper flow and pressure output settings are a good safety practice. In addition, it is a good idea to have your hydraulic power supply equipment tested and calibrated on a maintenance schedule. Today’s new generation of larger-pitch diamond chains is much stronger than previous versions of chain. This can lead to operators becoming more confident in concrete chainsaws and even, in some cases, exceeding hydraulic flow supply specification. Despite the increased strength benefit of the newer, large-pitch chains, it is not recommended to discard manufacturer’s instructions and specifications. The documentation provided by the manufacturer should always be read, understood and adhered to. The two prominent safety measures of the chain side cover and guard flap should never be compromised, and operators should make sure these parts are present and securely in place before

process is managed correctly following the incident. Personnel required to conduct the actual investigation should be dispatched to the scene of the accident as soon as possible. The accident scene is actually the best time for some companies to get their attorney involved. This is particularly true if the company has an affiliation with an attorney who is familiar with litigation involving liability issues. There are numerous reasons to involve an attorney from the beginning. The objective of this notice procedure is to ensure that the attorney is included in all communications to preserve the company’s privileges (attorneyclient/work product) of nondisclosure should civil litigation arise. For instance, the investigative materials, including internal accident/ incident reports, photographs and statements created with an attorney’s input and advice, may not be disclosed to the opponent in the future unless for strategy.

Scene Investigation The next phase should be conducted by the minimum number of required company personnel to adequately oversee the process. This way, if a lawsuit materializes there will be fewer people available to sit for a deposition as witnesses. A few years ago, an unfortunate incident occurred near the home of a CFO of a corporation. He decided to assist with the investigation because it occurred on a highway near his home, which turned him into a critical witness in the case, even though he didn’t see the accident occur. Obviously, his deposition lasted longer than anyone in the case, including the driver involved in the accident, simply because he knew so much about the intricacies of the company—a plaintiff lawyer’s dream. Rather than being protected by the “work product” or “corporate veil” objection typi-

and their family members from the outset. If the vehicle involved is owned by the company, the location to which the vehicle is being transported to should be obtained while on the scene. Instruction should be given to the towing company to avoid altering the brake system of the vehicle, due to the need for testing by State and Federal investigators and company personnel. Many informed plaintiff attorneys also want to inspect the vehicle prior to any changes being made. If the vehicle is altered or repaired prior to inspection by the opponent, then legal ramifications can result such as spoliation of evidence. A letter can be sent, offering the other party involved in the accident, the opportunity to view the vehicle, together with a ten-day deadline for non-response. Likewise, a contractor can make a request to inspect the vehicles owned by other persons involved in the accident. In addition, computer data from the vehicles should be obtained prior to any changes or repairs taking place. In order to preserve the condition of the roadway, and potentially the final rest of the vehicles involved, an aerial photograph can be ordered. Over time, weather and traffic will remove skid marks from the surface, and shrubbery can change rapidly. The cost associated with an aerial photograph is typically well worth the investment for scene preservation.

Incident Report If an attorney is assisting with the incident report process, it should be titled “Work Product - Internal Incident Investigation” which will help guard against the information being distributed outside the company or its representatives. This should include a detailed analysis of how the incident occurred in chronological order, diagram of the scene, a summary of witness statements, preventative measures, future action or safety training and an index identifying all documents and photographs generated or gathered during the investigation. Upon completion of the investigation, the appropriate personnel can discuss the results and build this experience into a company-wide safety awareness and accident prevention campaign. Although there are many other facets of investigating incidents that could be covered, following this outline of tasks will be highly beneficial for any contractor should they receive unfortunate news. Michael D. Logan joined the legal firm of Adams, Coogler, Watson, Merkel, Barry & Kellner, P.A. in 2003, becoming a Partner in 2008. Logan concentrates his practice on personal injury, trucking, auto, products liability, premises liability, construction, criminal law, traffic and medical malpractice.

First Brokk 260 in Canada Derrick Concrete Cutting & Construction LTD.

Brokk 260 Weight: 6,724lbs Height: 60.2in Width: 47.2in Reach: 19ft Breaker: 1000ft.lbs Power:22kW

Since 1976 Derrick Concrete Cutting & Construction has maintained a reputation for high integrity, dependability, and quality. By combining highly trained and qualified personnel along with purchasing top of the line precision equipment Derrick has managed to stay ahead of the competition.

In a market that is always changing with new safety restrictions the Brokk always comes out on top.

The Brokk line of equipment has been a valuable piece of equipment to our company since the first purchase of a Brokk 150 and 250. We have since upgraded to the Brokk 180 and the new Brokk 260.

The flexability of the machine’s 360° movement and close to six meter reach allows the Brokk 260 to work on walls or staircases with ease. The electric power makes it ideal for inside or confined locations.

Brokks performance on service, parts and training has been second to none.

As times get tough, it is difficult to spend money on equipment but Brokk has always been a wise choice for my company.

I can confidently say that the Brokk line of equipment has gotten us work combined with our cutting operations that we would have never got if we did not have the Brokks.

The flexibility to having other attachments such as crushing jaws, scarifier, grapple and shears makes the Brokks even more valuable in our fleet of equipment.

Why I joined CSDA Like most people in business, we have asked ourselves ‘why should we join an association?’ before we actually became members. Over the years we have joined several different organizations looking for a good fit. With one in particular, it seemed like all we were doing was sending money for the privilege of saying we belonged to that association. During that period we had always taken time to stop by the CSDA booth at World of Concrete.We were impressed with all the information they had, and there always seemed to be something

A number of years ago a member was considering not rejoining. In a phone conversation with the contractor, I realized that this member was not reading any of the materials sent from CSDA. The materials provided to members, especially small members, are invaluable in helping cutting contractors succeed. The contractor said he would review the material we sent and I don’t really know if he did or not. But a couple of years later, he went out of business. My guess is that he did not read our communications.

The DM 330 electric drill motor has a 3-speed gearbox and is available in low speed and high speed models. The high speed model is capable of 350/780/1340 rpm under full load and 240/540/930 rpm for the low speed model. The models can accommodate a wide range of drill bits, from 1" - 14" in diameter. The LED indicator shows the load of the machine and makes it possible for the operator to drill at maximum pressure for best performance. The drill motor is equipped with ElgardTM overload protection, SoftstartTM which limits the current for a smoother start and SmartstartTM that reduces speed and simplifies the initial stages of drilling.
