Replacement of Vancouver Stadium Roof Aided by Diamond Tool Cutting

A stadium with the world’s largest air-supported roof was in need of improvements following a “deflating” incident in 2007 caused by a tear. In 2009, funding was approved to upgrade the Vancouver stadium’s infrastructure, plumbing, electrical systems and install a new retractable roof. The upgrade work included concrete cutting with diamond tools in various parts of the stadium and scanning with ground penetrating radar (GPR).

Columbia, Canada. The

stadium opened in 1983 and is the home of the BC Lions CFL football team and Vancouver Whitecaps FC MLS soccer team. BC Place was also the Olympic stadium during the 2010 Winter Olympics and the 2010 Paralympics. In January 2007, a tear occurred in the roof that led maintenance teams to perform a controlled deflation of the roof. The tear allowed large quantities of rain and snow to enter the stadium, which then needed to be pumped out. The following year, it was announced that a number of renovations would be made to the stadium, including the replacement of the air-supported roof with a retractable, steel frame roof with cable supports. The concrete cutting work involved the modification of 54 existing structural supports for the installation of new structural supports, almost 500 feet of expansion joint cutting, GPR scanning of various concrete structures and the cutting and removal of sections of the concrete support slab for the playing field to accommodate a new drainage system. Precise and flat edges were required for the new mounting plates and brackets, and cutting could not interfere with other existing concrete structures that were to remain. Access in many areas was tight, so detailed planning of dust and water controls were required to guard against these hazards building up while cutting. PCL Constructors Westcoast Inc. of Richmond, British Columbia, was appointed the general contractor for the work and immediately was given a tight timetable. The Canadian Football League’s Grey Cup Championship Game is to be played under the new roof on November 27, 2011. Prior to this date, the BC Lions are scheduled to play their first home game at BC Place on September 30, with a Vancouver Whitecaps FC game following

Cutting Contractor Aids I-10 Twin Span Bridge Replacement


oncrete cutting with diamond tools is being used on a number of projects throughout Louisiana to help the state recover from the damage caused by Hurricane Katrina in 2005. Transport links and

infrastructure were rebuilt or repaired as soon as possible following the disaster. While a new twin span bridge was constructed to reconnect two cities in eastern Louisiana, the old damaged bridge spans remained. Having been marked for demolition, these damaged concrete spans required subtle and precise cutting to safely remove them from the area. The work began in April 2011 and consisted of around 100,000 linear feet of sawing, including cutting depths of up to 40 inches. The Interstate-10 Twin Span Bridge runs north and south across Lake Ponchartrain and links Slidell to New Orleans. The original spans were opened in 1965 and consisted of 433 65-foot concrete spans. Each span was two lanes wide and had clearances of 8.5 feet for most of the bridge, with a 65-foot clearance at the bascule bridge section. The new twin span bridge is located just 300 feet east of the old spans and has three lanes running in each direction. It stands 30 feet above the surface of the lake with an 80-foot-high section near Slidell. Each span is 60 feet wide. The selective saw cutting of the old twin span bridge sections involved the demolition, removal, processing and recycling of concrete decks, pier caps and beams. This was part of the Louisiana Department of Transportation’s recycling program to reuse damaged structures for revetment shore protection systems. To comply with parts of the program, all slurry and waste material had to be kept to an

Hydraulic Versus High Frequency— Wall and Wire Saw Technology in the Concrete Sawing and Drilling Industry By Johan Ekström


hen cutting large concrete areas, a wall or wire saw can be the ideal piece of equipment for the job. Wall and wire saws have typically been powered by hydrau-

lics, but now contractors have a choice between hydraulic or high frequency machines. High frequency technology has been around for over 30 years, though it took some time for this technology to become fully developed. Products were limited and not readily available in the marketplace, therefore it took a while to break into the hydraulic-dominated construction industry. It was not until the 2000s, when high frequency equipment was more refined, that acceptance of this technology grew. Since then, various high frequency products have emerged into the concrete cutting and drilling market, including high frequency wall and wire saws. It is important to look at the differences in hydraulic and high frequency wall and wire saws to understand how each operates, their maintenance needs and modern techniques. This will enable cutting contractors to best determine which is better for a particular project or for their fleet. Operation and Benefits Wall saws are built to cut through reinforce concrete, brick and other building materials to make openings, while wire saws are used to cut through larger concrete structures such as bridges, foundations and very thick walls. The end results are the same—precise, efficient cutting—but it is how hydraulic and high frequency systems work to achieve the end result that is the difference. Converters and Power Packs High frequency wall and wire saws produce enough power to move the blade or wire through the material to be cut. When using a high frequency product, the power supply is converted into greater power through a high frequency converter. For example, a 480-Volt, 60-Hertz power supply can be converted into 400 Hertz by a high frequency converter. There are a lot of different ways to measure power, but the most precise way is to measure at the blade shaft of the saw head. This provides contractors with a true measure of power in the system.

Wall saws use a track with a saw head attached, and the saw head is moved up and down the track to cut the material. Wire saws can be set up in an infinite number of ways—imagination being the only limit. With the use of swivel pulleys, the saw can be set up to cut in any direction, either pulling or pushing the wire through the material. Wall saws and wire saws have their specific applications, and in some cases one can be used to complement the other.

type of system, a high frequency motor will last for a long time, providing it is properly maintained. Many contractors feel hydraulics are more reliable because they do not have to be handled with as much care. However, a well-treated high frequency machine can be just as rugged and last longer than its hydraulic counterpart. High frequency equipment is built with electronic components and therefore operators have to take precautions when performing maintenance. If clean-up is done at the end of each day when debris is fresh, it can save time the next day after everything has dried. The rule of thumb is, “taking two minutes at the end of the day can save you 20 minutes the next.” Taking two minutes to flush the system and

The Center for the Performing Arts is a new entertainment complex located in the center of Carmel, Indiana, and officially opened in January 2011. The center includes The Palladium concert hall, the Tarkington proscenium theater and a 200-seat theater. The Palladium acts as a museum and education center by day and a concert venue by night. The 1,600-seat concert hall has been designed with a classical Palladio dome and the building’s concrete, steel and stone-clad structure is expected to last 500 years or more. Approximately 6,750 cubic yards of concrete were used in the construction of the building. Acoustics were of great importance to the design, but so was comfort. A heating, ventilation and air conditioning (HVAC) company was contracted to install individual air diffusers under each seat of the main concert floor and all balcony levels. This would provide the audience with a comfortable room temperature and minimize noise from the HVAC system.

Poynter Sheet Metal contracted CSDA member The Concrete Surgeons, also of Indianapolis, to core drill 840 holes in the main floor and balcony levels with diamond tools. The majority of the holes had to be 8.5 inches in diameter with some smaller holes of 6 inches on the balcony levels. All holes had to be drilled through a 6-inch-thick reinforced concrete floor and each hole was to be positioned to the exact specifications of the HVAC contractor. Work was to begin at the end of August 2010 and all drilling work was to be completed in three weeks. “There were strict dimensional tolerances for these holes and we had to maintain the structural integrity of the rest of the building as well. The holes had to be positioned precisely under each seat so that the air diffusers could be correctly installed,” said John Serban, owner of The Concrete Surgeons. “These were all reasons why we were selected, as our core drilling techniques met all of these requirements.” The layout of the holes was marked out by Poynter Sheet Metal so that the cutting contractor could get to work. The team from The Concrete Surgeons began by core drilling holes in the 6-inch-thick reinforced concrete concert hall floor. Of the 626 holes made, 68 had to be drilled through a 2-inch layer of rigid fiberglass insulation batts. Each hole measured 8.5 inches in diameter and took an operator around 15 minutes to drill.

drill supplied by Hilti and one Shibuya core drill supplied by Diteq Corporation were used to create the holes. The drills were fitted with core bits from Diamond Products. It took two operators 16 days to complete all of the 626 holes in the floor of the concert hall. The contractor then moved up to the second and third balcony levels of the hall to continue the drilling work. Operators core drilled 60 8.5-inch-diameter holes through the 6-inch-think concrete balcony floors, before completing the drilling work by drilling 38 holes that were 6 inches in diameter. The Concrete Surgeons created a total of 106 holes in the balcony floors over the course of nine days. Containing slurry and debris from the core drilling work was very important on this job. Had any slurry seeped through the floor openings, damage was possible to the fiberglass batts underneath the concrete slab. The Concrete Surgeons used trap rings around the core bits and the team vacummed as it core drilled to control the slurry. A wet vacuum was used to collect the 577 gallons of slurry created during the course of the job. The core drilling work at The Palladium concert hall had a fixed schedule of three weeks for completion. The cutting contractor assigned two core drill operators to work eight-hour shifts to complete the required 840 holes. The holes were completed one full day ahead of schedule due to the contractor’s ability to select the right core bit for the job, as well as the holes being drilled quickly, efficiently and precisely.

The main concert hall was cordoned off, while operators used harnesses when working on the balcony levels.

Save a Life with Hands-Only™ CPR By Erin O’Brien


ost of us understand the importance of having formal training in emergency response, such as first aid or cardiopulmonary resuscitation (CPR). However, most workplaces

still lack an abundance of trained healthcare providers. This has led the American Heart Association (AHA) to issue new guidelines that promote a life-saving procedure anyone can do, even without training. Hands-Only™ CPR is now being promoted by the AHA as a viable method in treating heart attack victims and will potentially save thousands of lives. Cardiovascular disease, which can cause heart attacks, is responsible for one out of every three deaths in the United States. This equals one death every 39 seconds. A 2010 AHA report showed that effective bystander CPR, or Hands-Only™ CPR, provided immediately after sudden cardiac arrest can double or triple a victim’s chance of survival. Hands-Only™ CPR removes the responder’s responsibility of performing an airway check and giving breaths to the victim, so that the steps are easier to follow. This technique should be used when a co-


worker suddenly collapses or is found unresponsive.


Check for consciousness.

If the victim is unconscious or showing signs of a heart attack, call 911.

Survival rates for heart attack victims receiving Hands-Only™ CPR are similar to survival rates for victims receiving traditional CPR. This is a simple procedure that should be taught to all employees in the workplace, whether workers have received formal training or not. Besides Hands-Only™ CPR, there are other steps workers can take to help a co-worker who may be having a heart attack. Noticing the risk factors and signs of a heart attack can lead to early detection and early response, decreasing the effects of the heart attack and raising the odds of survival. Risk factors include: •

Poor diet

More information, including a video demonstration, can be found on the AHA’s Hands-Only™ CPR website, The important thing to remember is that two steps–calling 911 and performing chest compressions–may save a co-worker’s life. Concrete cutting company owners, managers and workers should all familiarize themselves with this simple procedure.

How To Best Think About Loans For Your Business By Ami Kassar


ne important lesson learned from the economic crisis we have lived through, is not to jump into debt head-first. Debt can, and should, be an important part of your business, but you have to think about it carefully and thoughtfully. A bad loan decision can send you and your sawing and drilling business spiraling out of control. If you think that you might need a loan, the first step is to sit down with a pencil and paper and ask yourself some important questions. First, how much money do you think you need to borrow and for exactly what purpose? You should challenge yourself to see if there are any creative ways to save on some of the expenses you are projecting. Once you have confirmed these numbers, try to estimate how much money you expect to make as a result of the loan and over what period of time. What is your most conservative projection? Do some math to figure out what monthly loan payment you can afford. It is then a good idea to run these figures by an accountant or financially-savvy friend. You need to have a good handle on how

If I choose to get out of the loan early, what penalties will I face? It is absolutely critical that you understand

all of these issues clearly before you sign a loan agreement. All too often businesses give up far too much collateral for the loan they received, then are subject to pre-payment penalties that were in the small print. This has sometimes ended with business owners in handcuffs. It is natural to focus on getting the best possible rate that you can, but sometimes it is worth paying a little more in order to have the flexibility to borrow more money in the future or to trade one element of the loan agreement for a better pre-payment penalty option. You do not have to use up all of your collateral in one go. Loans should be designed to give the borrower the most flexibility. Always push your lender or your advisor to come up with two very different options for you. The choice and the differences between the two will help make sure you are focused on all five of the above questions.

Rail Good Cutting T

CSDA Member Cuts Bridge for New Decorative Railings

In April of 2011, a project commenced that involved the removal of almost 5,000 feet of steel-reinforced concrete posts and railings at the Blue Heron Bridge on the southeast coast of Florida. The posts required precise cutting so that new decorative railings and light fixtures could be installed and give the bridge a much-needed facelift. A local CSDA contractor member was given the opportunity to be part of the renovation work.

he job consisted of removing 4,830 feet of existing railings and cutting 860 posts on both the eastbound and westbound sides of the Blue Heron Bridge, which connects Riviera Beach and Palm Beach Shores near the coast in southeast Florida. The bridge has around 23,000

motorists cross it every day. The existing reinforced posts measured 10 inches wide by 10 inches thick and needed to be detached from the brush curb. The removal of these posts would allow for the installation of the decorative railings. The main challenge facing the chosen contractor was to contain all debris and minimize the amount of slurry created by cutting, as the bridge is located over a waterway. The cuts had to be precise so that the new decorative railings could be placed correctly. It was also important to avoid high levels of vibration during the work to maintain the structural integrity of the existing bridge span. Based

The eastbound side of the Blue Heron Bridge had 2,415 feet of concrete railings that required cutting.

Some of the specified cutting areas in the bridge deck and cantelevered sidewalk contained reinforcing rebar, so operators had to be prepared to encounter this rebar while cutting and avoid severing any of it. It took two operators 11 days to create the 11 trenches. ABC Concrete Cutting—South Florida also performed some core drilling on the Blue Heron Bridge. Operators used a Weka core drill from Diamond Products to create 2-inch-diameter holes 2.5 inches deep over vertical rebar. The operators then chipped out any remaining concrete. This was done to allow the general contractor to burn steel and epoxy holes to eliminate delamination of existing steel and concrete.

Each cut took around 10 minutes. Once the vertical cuts had been made, the cutting team proceeded to position the mini excavator with wall saw attached to begin the horizontal flush cuts. The cuts were made at the brush curb to detach the railings from the curb. The posts and railings were attached to a Case 590 back hoe with lifting chains and straps as they were cut. This made sure the concrete sections did not fall from the bridge into the water and allowed the contractor to lift the pieces from the cutting area onto a truck for removal. It took three weeks to complete the 2,415 feet of horizontal cutting. The next task for operators, was to score cut and chip 11 trenches measuring 5 feet long by 2 feet wide to a depth of 8 inches. These trenches were required for new light posts to be installed on the bridge. w w w.CSDA.ORG

For the Record— OSHA Recordkeeping and Reporting Requirements and State Variations By Mark A. Lies II and Elizabeth Leifel Ash


oday, OSHA regulations govern day-to-day operations and have a direct effect on employee safety. As a result, it is easy for OSHA’s more prosaic recordkeeping and reporting requirements to get lost in the shuffle. However, OSHA can issue citations to

employers for failing to follow recordkeeping and reporting rules, just as it can for machine guarding or lockout/tagout violations. In 2009, OSHA introduced a National Emphasis Program (NEP) target-

ing injury and illness recordkeeping on the OSHA 300 Log, designed to expose violations of recordkeeping regulations. While many employers will not be subjected to a NEP recordkeeping inspection, even a routine OSHA inspection will now focus on recordkeeping. It is critical, therefore, for employers to keep up with changes to OSHA’s recordkeeping and reporting requirements and to be aware of state-specific variations depending on where the employer does business. Injury and Illness Notification Requirements Federal Part 1904 of OSHA’s regulations contains the employer’s obligations with respect to recordkeeping and reporting of occupational injuries and illnesses. Under the current rules, an employer must notify OSHA within eight hours of the death of an employee from a work-related incident, or the in-patient hospitalization of three or more employees as the result of a work-related incident. Recently, OSHA announced a proposal to revise its injury and illness notification requirements. The proposed revisions would require employers to notify OSHA within eight hours of any work-related in-patient hospitalization, regardless of the number of hospitalized employees, and within 24 hours of an amputation. This proposed revision would result in a significant increase in the number of cases that would require notification to OSHA. Because an OSHA inspection is often triggered by an employer’s notification of a fatality or catastrophe, an increase in the number of “reportable” events would also increase the number of OSHA inspections. OSHA is accepting comments on the proposed rule through September 20, 2011. A copy of the proposed rule can be found at State Notwithstanding federal regulations, many states operate their own occupational safety and health programs and have varying injury and illness notification requirements. For example: •

Washington—Employers must notify the state agency when two or more employees are hospitalized due to a work-related incident.

California and Utah—Employers must report all serious injuries to the respective state agency.

4 2 | s e pte mb e r .11

Kentucky—Employers must report any amputation suffered by an employee within 72 hours of the incident.

Injury and Illness Recordkeeping In addition to reporting fatalities and catastrophes, OSHA requires employers to maintain an OSHA 300 Log for all work-related illnesses and injuries that meet any of the following criteria: •

The employee was off work for one or more days, excluding the date of the actual injury or the onset of illness, because of the injury or illness

The employee experienced one or more days of restricted duty as a result of the injury or illness

The employee received a job transfer as a result of the injury or illness

The employee received medical treatment beyond first aid

Tips to Avoid Common Pitfalls in Injury and Illness Recordkeeping Evaluate work-relatedness carefully. This can be a particular challenge where an employee is suffering from a musculoskeletal disorder or respiratory illness that developed over time. Where the cause of a particular injury or illness is unclear, the employer must evaluate the employee’s workplace activities to determine whether work activities were a discernible cause of the injury or illness. Consultation with a physician is

In light of OSHA’s National Emphasis Program on recordkeeping, and the proposed revisions to the injury notification regulations, employers must be diligent in evaluating and properly recording work-related injuries and illnesses. During a recordkeeping inspection, OSHA will request first aid logs and interview employees to find out about injuries and illnesses that may not be included on the employer’s OSHA 300 Log. Employers are advised to consider the following statements to ensure compliance with recordkeeping and notification requirements. •

Controlling Losses at the Jobsite By Bob Elster


here are several issues for concrete sawing and drilling contractors to consider when controlling losses at the jobsite. It is important for

contractors to be aware of these issues and be well prepared for a project that requires materials, tools and equipment to be stored at the jobsite. By taking steps to properly secure property at the jobsite, whether it be materials, tools, equipment or vehicles, contractors can guard against theft and damages that can cost a company time, money and manpower. Jobsite Protection for Building Materials, Tools and Equipment Make sure to store materials in an area where trucks can deliver or haul it away easily. Employees should also have easy access to these materials so that forklifts can operate safely. Theft of building materials and equipment, especially in areas where large quantities of material are stored, is a serious concern

for many contractors. The installation of high fencing, outdoor floodlights and some type of alarm system is recommended. Signs displaying “No Trespassing” should be posted around the perimeter of the insured’s jobsite or on temporary fencing. Lock boxes or locked storage sheds can be helpful in preventing the theft of tools and equipment from the premises. On larger jobsites, hiring a guard service to patrol the site during off hours is also advisable.

Under some state laws, the driver of a company vehicle or even the employer can be held liable for damages that occur as a result of using cell phones or two-way radios while driving. Contractors should consider take greater care of the company vehicle and drive safer if they are aware their employer is actively monitoring their driving habits. If equipment and supplies are not properly secured on trucks before being hauled to jobsites, this could result in damage to other vehicles and drivers. In terms of waste materials from concrete cutting, loose debris on a truck could fall and cause serious damage to other vehicles or even bodily injuries to drivers or passengers of those vehicles. Many states have “tie-down” laws, which mandate the tying down of loose materials that could be blown or spilled onto roadways during transport. Contractors should be aware of the laws that apply to their state(s) of operation and review information for other states via their

prohibiting the use of handheld cell phones while driving and encourage workers to pull over if they need to make a call. Cell phone and radio safety rules can be discussed with all designated drivers and hands-free devices, such as headsets, can be provided. Several states have issued bans on the use of handheld cell phones while driving. Contractors are advised to pre-program the most frequently dialed numbers into company phones or use phones that are voice-activated to minimize driver distraction. All truck drivers operating vehicles that can carry more than 26,000 pounds or more must hold a commercial driver’s license (CDL) issued by the state in which they reside. Drivers who have a Class A endorsement on their CDL may

Mobile Equipment Issues Concrete sawing and drilling contractors will have significant inland marine exposure due, primarily, to the fact that they will require a mobile equipment floater policy for protecting valuable equipment like cranes, forklifts and front-end loaders. Smaller equipment can be protected with a contractors’ equipment floater policy. Valuable papers and records coverage is recommended, and an outdoor sign floater policy may also be required. Contractors often have to move large quantities of waste materials like concrete debris and slurry. This requires the use of heavy equipment like forklifts, front-end loaders and cranes. Some contractors may also own hydraulic jacks and/or mobile manlifts. Large or valuable pieces of heavy equipment should be protected with coverage equal to what it will take to replace that equipment. Contractors should make sure equipment schedules clearly state the number, type and configuration of the insured’s mobile equipment. While such items are unlikely to be stolen due to their large size

and awkward handling, the physical appearance of heavy equipment can make it an attractive target for vandals. If mobile equipment is to be stored at a jobsite overnight, the contractor should assess the security measures available to minimize the potential for vandalism. If such equipment is stored in a garage or shed, doors should be kept locked whenever the equipment is left unattended. The jobsite should be surrounded by sturdy fencing with “No Trespassing” signs prominently displayed and be equipped with outdoor floodlights. Depending on the total value of the equipment at the jobsite, a contractor may wish to hire a security guard to patrol the area during off hours. Portable, handheld tools and equipment should be protected under an Equipment Floater. Smaller pieces of equipment could be stolen while employees are focused on performing their assigned tasks. Over time, such losses could accumulate and result in substantial losses. There are several ways to monitor the whereabouts of portable tools and equipment at jobsites. Upon completion of a job, employees should double-check the area for any items they might have forgotten. Equipment inventories should be created and regularly checked. Contractors should evaluate how valuable tools and equipment are secured when not in use and make adjustments where necessary. Tools can be stored in a lockbox or storage shed at jobsites to improve security. A sign-in/sign-out sheet can be created for employees when using handheld tools or equipment. This sheet can be monitored or countersigned by an assigned site supervisor. By following the advice and suggestions given here, sawing and drilling contractors can control and reduce losses at the jobsite and improve their insurance mods. Some of the suggested controls should not be difficult for








many contractors to implement, but can make a big difference to a company’s bottom line.

Comprised of a DM 280 motor and a DS 450 drill stand, the DMS 280 drill rig is full of features that enable the user to operate the machine safely and efficiently. It is perfect for a variety of applications, including openings for ventilation and plumbing as well as holes in corners for wall saw openings. The motor is equipped with a LED indicator to show the load of the machine and to make it possible for the operator to drill at maximum pressure for best results. The two-speed carriage gearbox allows optimum feed pressure to be applied on different diameter bits which enables the bits to run at their maximum performance level. The motor and core bit travel smoothly on the column with minimal adjustment thanks to the V-groove roller carriage. With all these features, the DMS 280 drill rig is one powerful machine.

Keeping you ahead of the game.
