rewards associated with employing highly skilled, welltrained personnel outweigh the costs of training. In 2009, overall training expenditures by U.S. companies decreased by just seven percent from the previous year to $52.2 billion, as stated in Training magazine’s 2009 Industry Report. However, in the same report it states that 57 percent of the companies surveyed maintained the same number of training staff as the year before, and small companies of 10 to 999 employees were increasing training expenditure while allowing more hours for staff to be trained. In fact, these small companies more than doubled their amount of training hours per employee to an average of 33 hours in 2009. The positive effects of training employees can be huge, whether the company is involved in contracting, manufacturing or distributing. These effects are not simply in terms of skill levels or profits, but also through raising employee morale and building a productive and healthy working

rience is invaluable in most cases, the introduction of new tools and equipment can often place them in the same situation as a newly-hired employee. Training has no age limits. To keep up with how quickly products and technologies advance, the methods with which employees are trained must also evolve and improve. At a time when employers are thinking “outside the box” as to how to cut back on costs, while still getting their operators sufficiently trained, the increasing popularity of online courses and webinars proves just that. It goes without saying that there is no substitute for having handson training when it comes to increasing the skill and safety of employees, but the rapidly-evolving service of web-based training has given many employers a more cost-effective way of educating and informing their employees. Training institutions continue to adapt course offerings in response to the ever-changing needs of the industries they serve. Tutelage is provided by industry experts, who share a wealth of information with students about their chosen discipline. By using proven, well-structured courses as a company training program, participants are assured of receiving top-notch instruction through the presentation of up-to-date best working practices. Since 1993, Concrete Sawing & Drilling Association (CSDA) members from the U.S., Canada and around the world have been sending representatives to the association’s training classes with the aim of enhancing or adding to the skill sets of their employees. Participants have discovered the benefits of being given quality training and take their newly-acquired skills back to their respective companies. The information and techniques presented enable participants to work with increased levels of accuracy and efficiency in their day-to-day roles, heightening the reputation of their company, improving safety records and showing customers that professionalism and safety are top priority. “By sending our employees to structured training programs and having most operators become certified in their field, the company has been able to win more jobs and impress customers with the professionalism of our guys,” says Kellie Vazquez, vice president of

by showing potential customers that employees have attained a high standard in their chosen discipline. Evidence of training and certification is becoming an important part of a company’s portfolio when bidding for jobs or presenting to potential customers. With the advancements in online training, it is now possible to acquire such documentation while sitting in your own home or office. As previously mentioned, however, the accessibility of online training cannot compare to the opportunity to send employees on hands-on and classroom courses. Interaction with experienced trainers and other industry experts, and the chance to use and learn about the latest cutting equipment and techniques, is one resource that an employer is hard pressed to find anywhere else. Many organizations work with local training or educational facilities to provide the best possible environment in which to conduct training classes. This benefits both the facility and the organization, as attendees can be trained in a location dedicated to their discipline, and the educational facility can show students that professional organizations from their chosen industry use their location as a base for training. Students have a firsthand look at the work performed by the class attendees, while the attendees take advantage of being in an academic environment with modern equipment and facilities. you and your company from potential claims,” he added. With all the technological advancements present in today’s society, it is becoming clear to many that online training is a great option if costs or employee time off are issues. It is important to remember that training need not be limited to contractors, but can be extremely useful to other industry employees. Manufacturers and distributors of goods and services have found that training has enhanced the knowledge and skills of their workers. By gaining enhanced knowledge of the relevant tools and equipment, and learning how to get the best performance from them, employees are able to interact confidently with customers and use their firsthand knowledge to answer any questions about their company’s products. “We were expanding the business into the professional concrete

n a stretch of the Tocantins River in Brazil stands the Tucurui Dam. With 120,000 cubic meters (approximately 4.24 million cubic feet) of discharge capacity, the dam spillway is one of the largest in the world. A massive engineering project was designed to open up this part of the river so that it could join with the Araguaia River and flow into a basin deep within the Amazon. Part of the plan at the Tucurui Dam included the removal of a large concrete emergency closure arch at one of the dam’s locks. A solution was required to remove the arch quickly and safely.

The Tocantins and Araguaia Basin is the largest river basin in Brazil, spreading more than 300,000 square miles. In 2007, the Brazilian government launched a Growth Acceleration Program that included opening up the country’s waterways to increase economic growth as well as providing better infrastructure between the inland areas of the Amazon Basin with the country’s shipping ports. As part of this program, the emergency closure arch at the Tucurui Dam Lock #1 was cited for removal. This reinforced concrete structure measured 39 meters (128 feet) wide, stood 25 meters (82 feet) high and was 1.5 meters (4.9 feet) thick.

were created by the wire saw. The progress of the horizontal cuts was slower, and it took the contractor six days to make each of these cuts. Each of the 220 reinforced concrete sections cut and removed were 3.9 meters (12.8 feet) tall by 1.1 meters (3.6 feet) wide. The weight of each piece varied due to the differing thickness and reinforcement throughout the emergency closure arch. Cut sections from the top-center of the arch weighed 9.25 tons, while the pieces from the bottom of the arch and close to the sides weighed up to 54 tons. As these heavier sections exceeded the maximum 30-ton weight allowance of the trucks that were transporting them from the job site, further cuts were made to the concrete once craned out from the work area, creating pieces that were more manageable. The cuts made by the wire saw were so clean that the concrete sections were reused on the Tocantins as retaining walls and placed in certain areas to protect the river banks against erosion. The cutting and removal of the emergency closure arch at the Tucurui Lock #1 was completed on the 90-day schedule set and without incident, although the job did present a number of challenges to the cutting contractor. The location of the job was isolated from the urban areas of Brazil, deep within the Amazon. The supply of equipment and spares had to be planned far in advance to insure against potential delays to the work. The sheer size of the structure that the team from EKIPE-C was working on was also a challenge. In order to maintain a safe working environment while cutting, the contractor performed

EKIPE-C successfully demonstrated to the general contractor and to the dam owners that controlled demolition with diamond wire sawing was the best solution for the demands of this job. The cutting of the emergency closure arch was completed on time and within budget, and highlighted the speed and efficiency that cutting with diamond tools can bring to many jobs. As a result, the cutting contractor was awarded another job that involved the creation of several water intake openings in the lock walls. This job had been started by another contractor, but the use of jackhammers had caused the work to fall behind so EKIPE-C stepped in with its wire saw to get the job done.

last-minute change in the construction of a new building in Vancouver, British Columbia, Canada, meant the general contractor had to enlist the help of a specialized concrete cutting contractor to ensure the project finished on time.

During the pouring of a rooftop air conditioning pad, a variation in the design of a rooftop garden area was made and the pad required adjustment. The clock was ticking down on the official opening of the building, so speed was of the essence. The air conditioning pad was poured to stand 20 inches high, but the redesign meant the pad had to be only 4 inches tall. The pad measured 4 feet long by 4 feet wide and needed to be reduced so that the correct amount of concrete would remain for the air conditioning unit. In addition, the building is located in the most densely-populated area of Canada, Vancouver’s West End, and was days away from final occupancy. The main challenge that the contractor had to face, however, was time. The contractor had just three days from its initial contact with the general contractor to complete the work. The use of jackhammers and other traditional methods of demolition was not suitable due to the noise generated and the proximity of neighbors, so the general contractor, ITC Construction Group of Vancouver, needed to find a fast, clean and guaranteed way to remove the concrete in time for the opening of the new building. The construction group is one of the largest in western Canada and specializes in the construction of concrete residential and commercial buildings. ITC contracted CSDA member company Vancouver Concrete Cutting & Coring, Inc. (Vancouver CCC) to modify the oversized concrete slab. The general contractor had worked with Vancouver CCC on other projects and confidence was high that a solution could be found. Vancouver CCC devised a plan to dissect the concrete pad with diamond tools before coring holes into the concrete and pouring a substance that would expand and break the concrete from the inside out. “When ITC contacted me with this reinforced concrete removal job and told me that there was no crane on site, no three-phase power, it had to be done quietly to avoid noise ordinance issues and we couldn’t make a mess, I felt like both my hands were being tied behind my back,” said David McNamara, president of Vancouver CCC. “When the general contractor added that we only had three days to do it before occupancy, and it was already two o’clock in the afternoon, I knew that I had to come up with a solution for the customer that met their needs and timeline,” McNamara added. The contractor decided The building was to open in three days when a change of design was required.

to use Sylentmite in conjunction with sawing techniques. The powdered substance provides controlled demolition of a structure when poured into drilled holes at specific points. The initial plan was to saw cut the entire pad into pieces for removal, but insufficient power was available on the rooftop for electric or hydraulic motors. In addition, the side of the building was sloped so the general contractor wanted to minimize the amount of time hydraulic lines were run up the side of the building. The building was due to be occupied by its first residents in days, so it was specified that there was to be no slurry damage to a roof garden that surrounded the concrete air conditioning pad. Because of these constraints, Vancouver CCC came up with the idea of cutting a sizeable portion of the pad using concrete cutting equipment so that

work was to hit as much steel as possible. By hitting as much rebar as they could find, the team was able to eliminate reinforcement in the concrete that would have made the next part of the job more difficult to achieve. The drilling of the holes also took four hours to complete. Once the wall sawing and core drilling work was finished, operators from Vancouver CCC removed the cores and cleaned each hole to ensure they were free of dust and debris. The contractor then turned to its “chemical weapon,� Sylentmite. The powdered mixture of natural minerals, when mixed with cold water, can achieve up to 20,000 psi of expansive power. Vancouver CCC made the mixture and applied it to each hole created in the concrete pad. Within a few minutes, the mixture of powder and water started to increase in temperature and around an inch of material expanded out from each hole. Within two hours, cracks appeared throughout the pad. The mixture was left in the core holes overnight to allow the product time to fully expand, in which time the expansion of this mixture forced cracks in the concrete as wide as 1.5 to 2 inches. Once the process of expansion ended, the cutting team returned to the pad to chip out sections of the concrete. This chipping was required to reach some of the remaining rebar and cut it with an angle grinder, so that the pieces were in manageable size for the disposal team to remove from the job site. Working on the rooftop of this large building came with its fair share of challenges. First, no cranes were available or allowed on site while the building was so close to opening. The opportunity to utilize a crane may have enabled the cutting contractor to cut the concrete pad into larger pieces that could have been lifted out from the rooftop area of the eight-story building. All cut sections of concrete and waste materials had to be transported to ground level by residential elevator

Bridge Collapse Concrete Cutter Goes Underwater to Remove Fallen Structure A new bridge across the Tonola River was being constructed during the removal of the old bridge.


n July of 2009, one of the two reinforced concrete bridges that span the Tonola River outside the city of Agua Dulce in southeastern Mexico collapsed. As a large part of the 260-meter (853-foot) bridge was now underwater, the general contractor had to find a professional cutting contractor that could break down and remove the collapsed structure from the river bed.

The bridge was built in 1958 and consisted of seven segments of reinforced concrete, with each segment supported by reinforced concrete pillars and one foundation of 0.61-meter-diameter (2-foot) pilots. In 1988, the bridge was reinforced and in 2003 a new deck slab was poured. Following the collapse of the bridge, a project began to build a new bridge 30 meters (98.4 feet) up stream of the original. The project also included the task of demolishing and removing the fallen bridge at the same time as the construction of the new bridge. The Mexican Federal Police confirmed that the reason the bridge failed was due to the foundations of the pillars being gradually worn and damaged by the flow of the river. Puentes y Construcciones S.A. de C.V. was chosen as the general contractor for the demolition and removal of the existing 260-meter(853-foot) long and 9.5-meter- (31-foot) wide bridge. This general contractor then needed a specialized contractor that could work underwater to break the bridge into smaller pieces so that the concrete could be removed from the river by crane and transported elsewhere. CSDA member Soluciones Tecnicas y Profesionales ADRA S.A. de C.V. (ADRA) was chosen to complete this task. “We offered the customer a solution that had not been considered,” said Raul Bracamontes, owner of ADRA. “The company has a good reputation for underwater concrete cutting and we showed him what we had done before in Cozumel Harbor [as published in the December ’07 issue of Concrete Openings]. He trusted our skills and experience to complete the job,” he added. The cutting contractor was to perform all of the underwater demolition in the Tonola River. Working with the general contractor, the team from ADRA decided that the best way to successfully demolish and remove the sunken sections of the fallen bridge was to cut each of the five main deck structures into 18 pieces using diamond tools. Each

river bed by crane. The pieces would then be maneuvered to shore where they could be completely demolished with hydraulic hammers. This method was to be repeated for the other concrete bridge pillars. While the last part of the demolition process was to be carried out by hammers on the banks of the river, the rest of the work required a bit more precision. A main oil supply pipeline was located less than 20 meters (65.6 feet) from the work area, so the use of explosives to break up the sunken bridge was ruled out. In addition, the Tonola River is highly valued by the surrounding communities in Agua Dulce. For local fishermen, the river is their livelihood and any demolition work had to have minimum impact on the river, its inhabitants and the people who depend on it for food and work. Time was also a factor, and with a pre-defined eight-month period to complete the work, the contractor

The wire saw cuts dissected five 560-ton deck pieces and four 280-ton pieces from the piles. In addition, two more 560-ton sections were cut above water level at each end of the bridge that led down into the water, for a total weight of 4,480 tons. Although flooding in the area had caused delays to the specified completion date, the general contractor gave ADRA two more sections of the bridge that were originally awarded to others to cut. Also, the Mexican transportation secretary was so impressed with the contractor’s work that ADRA has since been awarded more underwater cutting jobs throughout the country.

of the tunnel at a height of 3.5 meters (11.5 feet). The cutting work for this phase took four days. This operation was repeated for each of the eight remaining blocks until this part of the cutting work was complete. To complete the third and final phase of the project, vertical and horizontal drill holes were created in the rock wall measuring 15 millimeters (0.6 inches) in diameter. The diamond wire was then passed through these holes so that cutting could commence. Wire sawing was performed simultaneously with two cutting machines with operators on rotating shifts over a total of three eight-hour shifts. Cutting work took the contractor a total of 10 days using a 60-horsepower wire saw from Bicoma with 9.8-millimeter-bead (0.4-inch) ORZ diamond wire. The cutting area was 800 square meters (8,611 square feet) and was done with 135 meters (443 feet) of diamond wire. For operators to work safely while performing cutting tasks at the Fort of Exilles, personal protective equipment was required to be worn at all times and harnesses were used when working on the exterior of the fort walls. Platforms were erected to position the wire saw on the outside of the fort and provide enough room for operators to maneuver around the equipment and set up the saw. Scaffolding was placed higher up on the wall and connected to the platform so that the cutting team could set up the pulleys for the wire saw runs. A series

We’ve got you covered.

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 inlcudes the new WS 482 HF and the WS 440 HF. The new WS 482 HF boasts more power, larger blade size capacity (62") and offers the best power-to-weight ratio on the market. It is radio remote control operated which allows total control of the sawing process and the 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.

Proper Care and Tensioning of Belts on Concrete Saws By Marty Marsic


he majority of concrete saws that are being used today rely on a belt to drive the blade shaft. The belt is a very con-

venient and efficient means of transmitting the power and motion needed to turn blades. Belts also serve as the fuse in the system. They are designed to slip, preventing overloading and damage to other components in the drive system. The goal is to adjust the belt tension so

I speak to business owners and ask, “What do you want?” They respond, “I want to make a profit.” I ask, “How much?”­­ —“As much as I can get.” “What if you can’t get very much?”—“That’s not enough.” “Then how much do you want?”—“More.” “More than what?”—“More than I’m getting now.” It becomes obvious that these people really do not know what they want, nor do they have a clear target to shoot for. Examples





“$500,000 net profit per year.” Specific. “Sales to be $1,000,000 per month,” or, “The project team’s goal is to make $50,000 on this job and get at least 2 referrals from the customer,” are also good examples. Leaders know what they

day business activities daily. Things go wrong, customers call with immediate needs, equipment breaks or people do not show up. These daily inconveniences pull you off course and take you away from your number one priority, which may be bottom-line profit, sales or customer service. You need a written plan to keep on track and measure your progress. I recommend written charts and graphs that can be posted for all to see. This clearly shows progress toward results.

and medium business owners take. They try to do too much and be everything to everyone, instead of staying focused, doing what they do best and only setting a few simple and attainable goals. People and companies without clear written targets and goals are surpassed by those that have them. It is very poignant to mention that those companies with written goals almost always achieve them. Those that do not have written goals often get the leftovers. I always ask, “Have you got a measurable target? Do you have three clearly defined goals? What do you want to achieve this year?” In my survey of over 2,000 business owners, only 30 percent had written goals for sales, overhead and profit. No wonder some companies struggle. Do You Use Scorecards? Can you imagine playing a golf course without greens? Score doesn’t matter. After four hours, you stop and go to the bar and start drinking. There would be no excitement. There would be nothing on the course to shoot for. No targets or scorecard. Sound bad? Sounds like most companies to me.

What are you really trying to accomplish? To get the results you want, you have to know exactly what you are shooting for and have a scorecard to keep track of progress. When you hit a bad golf shot, you can make the necessary adjustments to get back on course. In business,


you have different terrain and obstacles along the way to overcome. You need information and feedback to make adjustments as you go, targets to shoot for and a scorecard to keep track of progress. Get everyone involved by giving them clearly visible targets, written goals and a scorecard. Use Challenges and Incentives As a construction company owner, it often amazes me when I go out to a jobsite and ask the field superintendent, “When are you going to get this part of the project completed?” He says, “Well, I think we’ll get it done in a couple of months.” I then ask, “How did you come up with that completion date?” He then says, “Well, I talked to the subcontractor’s job foremen and we sort of agreed we could all get it done by then.” I ask, “Do you think you can finish it a week or two early?” He says, “Well, yeah, we probably could.” “Why don’t you?” “Well, there’s no real need to. We’re OK, we’ll finish it on schedule.” I say, “Wouldn’t it be better to

Offer competitive targets, challenges and encouragements like: “If I give you $100 for every day you finish early, do you think that might make a difference?” Then it’s, “Oh yeah, I know we can finish at least a week early, maybe even more.” Leaders clearly lay out what is wanted, draft a blueprint to achieve it and track the progress towards the goal. They also use incentives and challenges to get people focused to achieve the desired end results. When it is just the same old-same old, people often give the minimum

OSHA /CSDA Alliance Latest


he Alliance between the Concrete Sawing & Drilling Association (CSDA) and the Occupational Safety and Health Administration (OSHA) is now in its fifth 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. Most Frequently Cited OSHA Standards Through the Alliance Program, CSDA has developed products with the OSHA National Office that help employers comply with and workers understand the OSHA standards most frequently cited by OSHA inspectors. The list below shows the 10 most frequently cited OSHA standards in the fiscal year 2009. Most Frequently Cited OSHA Standards in Fiscal Year 2009 (Oct. 1, 2008—Sept. 30, 2009) 1. Scaffolding, general requirements, construction (29 CFR 1926.451) 2. Fall protection, construction (29 CFR 1926.501) 3. Hazard communication standard, general industry (29 CFR 1910.1200) 4. Respiratory protection, general industry (29 CFR 1910.134) 5. Control of hazardous energy (lockout/tagout), general industry (29 CFR 1910.147) 6. Ladders, construction (29 CFR 1926.1053) 7. Powered industrial trucks, general industry (29 CFR 1910.178) 8. Electrical, wiring methods, components and equipment, general industry

(29 CFR 1910.305)

9. Electrical systems design, general requirements, general industry (29 CFR 1910.303) 10. Fall protection, training requirements (29 CFR 1926.503) Employers and employees should be aware of the regulations within these standards and adhere to them. For more information, or to view these and other OSHA standards, visit OSHA /CSDA Alliance Release Toolbox Safety Talk The Alliance released its first Toolbox Safety Talk, entitled Sprains and Strains Prevention (CSDA-OTST-1001), in July. Sprains and strains account for about one third of injuries in the construction industry and, depending on the severity of the injury, can be simply an overstretch of a muscle or ligament or can result in a partial or complete tear. An injury like this can often hinder, and sometimes end, an operator’s career. This document provides details of safe working practices to reduce the chances of sprains and strains, and identifies common mistakes when moving objects in the workplace. The Toolbox Safety Talk is the fifth safety document introduced by the Alliance, having already released four Best Practice documents on the subjects of Highway Work Zone Safety, Reducing Silica Exposure, Defensive Driving and Electrical Safety. Three of these Best Practices are also available in Spanish.

OSHA Whistleblower Protection: Giving Sharper Teeth to a “Legal Dinosaur” By Mark A. Lies II and Meagan Newman


here is no question that the new Administration is cracking down on discrimination against whistleblowers.

Critics of the prior Administration claim that the Occupational Health and Safety Administration’s (OSHA) handling of whistleblower claims was lagging, if not deficient, and led to inadequate protection for employees who raise legitimate safety and health concerns. Still, the statistics for 2009 are not significantly different than those of prior years. In 2009, OSHA received 2,160 whistleblower complaints and completed 1,947 investigations. OSHA recommended litigation or otherwise

14 percent were withdrawn. The assistant secretary of labor for occupational safety and health, David Michaels, has said that he simply does not believe that the vast majority of whistleblower complaints are unfounded—instead he believes that institutional, administrative and legislative barriers to the complaints are behind the statistics showing unsuccessful complaints. As a result of these investigations, there has recently been a much more aggressive enforcement of the laws protecting whistleblowers in the workplace and a major push by OSHA to increase existing legal protections for whistleblowers.

Even prior to Assistant Secretary Michaels’ testimony before the Senate, there had been a push to pass legislation to increase whistleblower protections. Senator Edward Kennedy reintroduced the Protecting America’s Workers Act prior to his death last year. A similar bill had been introduced in the House by Representative Lynn Woolsey earlier in the year. Now, the legislation is seeing increased momentum. If passed, the Protecting America’s

Currently, OSHA whistleblower protection provision only allows for compensatory damages. Additionally, Assistant Secretary Michaels would like to add a provision that allows for temporary reinstatement of the employee pending the outcome of the whistleblower case, consistent with a similar provision in the Mine Safety and

experiences a fatality or work-related accident, it is incumbent upon the safety director to become proactive. After taking care of the reporting requirement to OSHA, the necessary OSHA forms need to be completed. Then, witnesses to the incident should be identified and contacted. It is advisable to contact the company’s attorney and have him/her on board from the very beginning of this process. The first part of the investigation procedure on a site is the opening conference. An OSHA Compliance Officer (CO) and other personnel will usually respond within one day of a report of a fatality or multiple injury. A CO will present his/her credentials at the site, gather information regarding the company, inform the employer of the scope of an intended walk-around and determine if employees are represented by a union. The employer should request that the CO present their credentials, including photo identification. It is suggested that the attorney representing the company is present at the opening conference. The company’s safety director should also be present at this meeting.

interfere with the CO’s orderly investigation. Therefore, the best available company representative should be present for this walkaround. Someone should be chosen that will act responsibly, and not cause the CO to feel it is necessary to stop him/her from going along on the on-site investigation. Keep in mind that private statements of employees are usually taken by a CO with only the employee present. In some instances, an employee representative may be present, such as a union representative, for this purpose. The employee is not required to inform the employer that they provided a statement. A suggestion is to provide a room with amenities such as coffee, water and snacks, where statements can be taken. Statements of managerial/supervisory employees are usually done with counsel present. Statements of witnesses and former employees are done in private without counsel. The CO will also take statements of emergency personnel, law enforcement, fire rescue, hospital workers and family. Statements of all of the above may be videotaped, recorded and transcribed. Witnesses may be asked to sign their statements. Companies should be aware of the informer’s privilege. This allows the government to withhold the identity of individuals who provide information about violations of the law. This privilege extends to the contents of statements to the extent that it would identify informers. Informers can authorize the release or waive the privilege. A CO will request documents from an employer. These documents include those

There is a closing conference conducted at the conclusion of OSHA’s investigation just prior to the issuance of citations. It may be conducted in person or by telephone. This is the opportunity for the company to negotiate any possible fines. Again, demonstrating cooperation, professionalism, forthrightness and having a strategy ready from the inception will serve a company well. Citations are issued within six months following the identification of violations. Fines are levied by the Occupational Safety and Health Review Commission. An employer has 15 days to challenge any part of OSHA’s findings after citations are issued. Citations There are several types of violations. The most serious violation is a willful violation wherein an employer knew that a hazardous condition existed but made no reasonable effort to eliminate it and the condition violated a standard or regulation. Penalties range from $5,000 to $70,000 per willful violation. A serious violation is when a workplace hazard could have caused an injury or an illness that would most likely result in death or serious physical harm, and the employer did not know or could not know of the violation. A penalty of $7,000 per violation can be imposed. An “other than serious” violation is one in which the most serious injury or illness that is likely to result cannot be reasonably predicted to cause death or serious physical harm, but it does have a direct relationship to safety and health. A penalty of up to $7,000 can be imposed. A “de minimis,” as the name

Before deciding whether to file a Notice of Intent to Contest a citation, the employer can request an informal conference with the OSHA area director to discuss the citation and notification of penalty. However, an informal conference must be held within the 15 working day Notice of Intent to Contest and will neither extend the 15 day contest, nor take the place of the filing of a written notice if the employer desires to contest. A Notice of Intent to Contest must clearly state what is being contested, the citation, the penalty, abatement date or all three or any combination thereof. Once a Notice of Intent to Contest is filed, the case is officially in litigation and is assigned to an administrative law judge. A citation and notification of penalty must be posted at or near the place where each violation occurred. If an employer has any questions regarding OSHA investigations, compliance assistance specialists who are former COs can answer any questions from the local area office. OSHA also provides various seminars and presentations to small companies, as well as large, concerning the information contained in this article, as well as many other safety issues.

The new K760 cut-n-break is the second Husqvarna machine with a new cut-n-break method. Husqvarna’s X-Torq® engine utilizes dual intakes for clean air and a fuel-air mixture. The K760 produces 75 percent fewer emissions and lowers fuel consumption by 20 percent. The saw features an improved ergonomic design and an effective vibration and sound dampening system, reducing operator fatigue. The cut-n-break method is a series of stages through which cutting up to 16 inches is achieved. The first step is to make a cut up to 2.5 inches deep with fast cutting, twin 9-inch blades. The remaining central core is then broken off using the breaking tool. Finally, successive cuts can be made to reach up to 16 inches deep. This cutting method can be used to create window, door and ventilation openings where overcutting is not desired. Cutting grooves for cabling, expansion joints and crack repair is also possible.

Seal/No Seal Group Formed A group of pavement industry professionals have joined forces to form the Seal/No Seal (SNS) Group. The SNS Group has been created to respond to the question about the value of sealing concrete pavement joints. According to the group, there is a lack of data in the industry to help guide owners about sealant effectiveness and the long-term impact of using or not using joint sealants. The goal of the SNS Group is to research and determine the cost effectiveness of sealing joints on overall pavement performance. This research will help establish actual construction costs for future

Hilti Introduces DS TS20-E Electric Wall Saw

DITEQ Promotes Two

Hilti has added a new wall saw to its range of equipment designed for use by concrete drilling and sawing service contractors. The Hilti DS TS20-E electric wall saw features high-frequency motor technology and Hilti Traction Control (HTC). The DS TS20-E can cut to depths of up to 21 inches. HTC, the electronic saw advance control system, ensures sawing performance by making full use of the electric power available. Drive parameters are monitored and measured continuously, while a digital control system calculates the optimum saw head advance speed. The DS TS20-E is a compact, mid-range electric wall saw with good power-to-weight ratio. When powered by a 32-amp supply, the DS TS20-E provides an output of 15 kilowatts and maintains a constant torque with all blade diameters — 24 to 48 inches — without need for mechanical gears. Blade speed can be adjusted to suit the blade diameter in use and the type of material being cut. The saw can be stowed on two trolleys and features lightweight but rigid guide rails. The carriage and blade drive motor form a single 77-pound unit, avoiding the need for a removable blade motor and motor mounting flange. For more information, contact Hilti customer service at 800-879-8000 in the U.S., 800-461-3028 in Canada or visit in the U.S. or in Canada.

The NEW tool for the job. The new K760 Cut-n-Break, a further development of the popular K650 Cut-n-Break, features a more powerful engine, enhanced ergonomics and reduced emissions. Equipped with Husqvarna’s low emission X-Torq® engine, the K760 Cut-n-Break produces 75% fewer emissions and lowers fuel consumption by 20%. The power cutter also features a vibration and sound dampening system which helps reduce operator fatigue. The Cut-n-Break method allows you to cut in stages through walls up to 16" thick. Initially, a cut up to 2-1/2" deep is made with fast cutting, twin 9" blades. The remaining central core is then easily broken out with the companion breaking tool. Finally, successive cuts can be made to reach up to 16" deep.
