Cutting Concrete for Concourse C

The NEW WS 440 HF Wall Saw. Husqvarna’s new WS 440 HF is setting a new standard for electric high cycle wall saws. The saw is based on a totally new technology, which gives the saw increased power for fast and efficient sawing. The powerful, water-cooled electric motor generates 17 horsepower to the shaft, despite the fact that the saw only weighs 55 pounds. The 9,000 rpm permanent magnitized motor delivers 100% power to the blade while cutting concrete or steel.

Core Drilling theCastle

To save one of Canada’s oldest and most beloved buildings, CSDA member carefully dry drilled 4,350 feet into its 100-year-old sandstone walls.

L

ocals have nicknamed the Victoria Memorial Museum Building (VMMB) the “Castle” because of its Scottish baronial style. Home to the Canadian Museum of Nature, this historic building in

Canada’s capital is undergoing a long-awaited restoration. The project will update every system in the Castle and create 22,000 square feet of additions. Crews will also return to the building something that was lost long ago—its signature entrance tower.

Architect David Ewart designed the building at the turn of the 20th century. Ewart’s design incorporated a towering front entrance to pay homage to Canada’s Parliament building. Scottish masons traveled

across the Atlantic to prepare the local sandstone for the VMMB, and construction began in 1905. Seven years later, the National Museum of

Natural Sciences (now the Canadian Museum of Nature) displayed its first exhibits at the VMMB’s grand opening.

By 1915, signs that the foundation could not support the VMMB’s weight could not be ignored. Cracks were appearing in the foundation and the massive entrance was tearing away from the building.

The Castle was sinking. Construction crews shortened the tower by 80 feet in an effort to stabilize the structure. Further stabilization efforts were made throughout the 20th century, including the Castle’s last major renovation in the 1960s.

Today’s rehabilitation project is expected to end the Castle’s longtime foundation problems. The most important improvement is the seismic framing system, a new steel frame that is being built directly into the existing walls and floor, then tied to the stonework. In essence, construction crews will create an endo-skeleton, or a building within a building, for the VMMB. Crews are dry drilling the walls to create access for the seismic frame installation. Dry drilling is necessary because the walls are constructed of sandstone, a very porous rock that would be damaged by wet drilling.

The seismic frame will provide enough support to restore Ewart’s original design intention. The Castle’s towering entrance will be re-created, but this time the structure will be made of glass. The tower includes a giant lantern, creating a sparkling draw for passersby as well as brightening the interior of the museum for its patrons.

Over 4,350 feet of dry drilling was required on this project. General Contractor PCL Constructors Canada (PCL) called in CSDA member company Capital Cutting and Coring (Capital) because of their established reputation of experience, teamwork and performance. Concrete sawing and drilling is generally chosen on jobs that require precision.

Sawing and drilling are also fast, efficient and cost-effective alternatives to demolition. Because the VMMB is a historic landmark, maintaining the structural integrity of the building makes precision concrete work like Capital’s a valuable commodity. PCL also took into account Capital’s proven ability to work in areas open to the public, keeping debris and dust contained.

The five-year restoration project for the Victoria Memorial Museum Building includes the installation of a seismic bracing system within the original sandstone walls.

Capital Cutting & Coring used a portable 8x10 steel platform to ensure that the Beretta T43 was perfectly level while core drilling the delicate sandstone.

Capital’s team began their work at the west entrance of the VMMB. They erected scaffolding outside the structure to provide safety and access to the walls and roof. Capital and PCL established regular safety meetings early on to keep everyone on top of safety and site cleanliness issues. Capital chose a Diamond Tech drill, the DT401, 110 volts with TB 50-torque booster to drill 6 holes, 4 inches in diameter and 35 feet deep. Operators used specialized K-2 Diamond bits, and kept the bits cool during drilling with compressed air.

Because operators were drilling into a porous rock, they encountered voids that made removing the cores more difficult than usual. They also ran across sections that had been filled with grout and loose rock.

Often these voids would jam up the drill and pulverize the core. Work progressed slowly as Capital’s crew extracted the troublesome cores.

Coring the west entrance eventually took close to 14 weeks.

The team moved on to the west chimneys with the DT401. Work consisted of 4 holes, 4 inches in diameter and 22.5 feet deep. Fortunately, the chimneys were solid. There were only two complications the crew had to manage: maneuvering the DT401 into very tight spaces in order to access the chimneys and drilling through a 1-inch-thick steel web at their base. Work on the chimneys went smoothly for the crew.

After completing the west entrance and west chimneys, Capital drilled test cores on their future work sites to learn the extent of the voids and debris within the sandstone. The east and west chimneys were completely solid, but the east entrance and main entrance were full of inconsistent rock and grout as well as voids, much like the west entrance. The main entrance was a concern because it constituted the

8 | JUNE.08 6 | 8september.08 JUNE.08

bulk of their work. It was also a high-profile job, as the work there would make way for the project’s signature feature, the glass lantern tower.

To core 48 holes at a depth of 75 feet on schedule would require more specialized equipment than Capital had in inventory.

Capital researched several options. A few drills fit the bill, but only one could be delivered in any reasonable amount of time: the Beretta model T43, manufactured in Italy. Capital also special-ordered 5.5 inch, 5-foot-long casings with a Numa hammer for the Beretta. As soon as the Beretta T43 was delivered, Capital’s team began training on the drill.

Once trained, the crew set up scaffolding and misting fans at the main entrance. Capital installed a portable, heavy-duty, 8 x 10 foot, steel platform to ensure that the Beretta was perfectly perpendicular to the drilling surface. Capital chose to use safe, biodegradable lubricants for the drill and hydraulic power pak. Not only would they avoid harming the 100-year old sandstone if a hose burst, but the fluids would be totally harmless to the environment as well.

Capital’s team began drilling with the Beretta T43 and slowed the drill down to limit debris spray. The crew core-drilled 48 holes, each 5.5 inches in diameter and 75 feet deep. All of their careful planning, training and preparation paid off. Capital completed the main entrance without incident. Capital decided to use the Beretta for the rest of the job. After they had completed the holes at the main entrance, seismic anchors were installed and grouted in 3-meter sections lifts.

Inclement weather conditions often made working impossible. The Capital Crew had to endure sub-zero temperatures as well as snowfall in excess of 190 inches.

A new, removed entrance was created for visitors to the museum while the main entrance underwent construction, including the 75-foot holes capital was drilling for the seismic brace.

Moving to the east entrance, they set up the scaffolding and prepared to drill 6 holes, 4 inches in diameter and 35 feet deep. capital worked expertly through the voids, grout and loose rock at this entrance. the severe canadian winter, however, was more difficult to manage. one hundred-ninety inches of snow fell during that winter, causing intermittent delays. when the capital team was able to work, it was in biting sub-zero temperatures. even so, the crew completed the east entrance on schedule.

Finally, capital set up their scaffolding at the east chimneys. they were still working in freezing temperatures and difficult-to-maneuver spaces. the chimneys also had a 1-inch steel web at their base, but capital was able to core drill the 4 holes without incident. Just like the

enver International Airport (DIA) is the largest airport in the United States by land mass. Situated on 34,000 acres

just 30 minutes northeast of Denver proper, the airport has over 6 million square feet of public

Constructed to replace Denver’s landlocked Stapleton airfield in 1995, DIA was designed for efficiency and growth. Passengers are screened in a central location and transported by rail system from DIA’s Jeppesen terminal, named for aviation safety pioneer Elrey Jeppesen, to one of three concourses. The airfield is arranged in a pinwheel formation around the terminal and concourses, creating an independent flow of aircraft to and from each runway without overlap. Taxiways are positioned to allow the expansion of each concourse as necessary.

DIA’s first concourse expansion is a 3-year, $160 million project that will add 8 new gates to the eastern end of the concourse. Part of the expansion calls for the installation of 4 moving walkways to ease traffic flow through the concourse. In order to install the walkways, construction crews would have to cut 4 large sections of 7-to 8-inch-thick concrete with pan decking.

And, each 160-by15-foot section would have to be removed while the concourse remained open to passenger traffic.

To limit issues with airport patrons, they decided to work at night, when the number of passengers would be at a minimum. PCL had already established a 10-foot tall barrier to keep pedestrian traffic contained away from the construction site.

Before DeAndrea could begin work on the concourse, the team members had to receive security clearance. Each worker was fingerprinted and background-checked. Paperwork, screenings and security classes required by clearance took an average of two weeks per person to complete.

Meanwhile, other construction delays meant DeAndrea’s work would have to wait a full week before startup. When the team was allowed access to the work site, several operators were still awaiting their security clearance. DeAndrea did not want to risk losing more time, so the team

T

he Pittsburgh Light Rail, called “The T,” is Pittsburgh, Pennsylvania’s 25-mile light rail system that functions as a subway between downtown and the suburbs. In 2006, the Pittsburgh Port Authority

initiated the North Shore Connector Project to extend the city’s Light Rail Transit system 1.2 miles. During the 5-year project, crews will tunnel under the Allegheny River, building an extension to the North Shore at a cost of $438 million. With 3 new stations, the connector will provide transportation to a projected 4.2 million riders a year. CSDA member company Matcon Diamond, Inc. (Matcon) was contracted to cut through 738 linear feet of 36-inch thick concrete near a major highway, to establish a roofline and drainage system for the new subway.

The wall saw was mounted in an upsidedown, or inverted, position in order to make the cuts flush with the exterior roof of the subway.

the team worked along the length of both walls, setting up the track and switching blades. A safety concern for which they had to be aware was the possible fatigue or failure of the flush cut bolts when using the 78-inch blade. Using such a large blade in an inverted position created significant stress on the bolts. operators had to replace the flush cut bolts in the final 20-foot stretch of cutting. nsc chose Matcon for this portion of the north shore connector project because of their previous work and proven ability to manage a tight schedule. their job was to cut the length of two walls above the future subway’s roof, to make way for proper drainage measures. the Matcon team used a remote saw and a series of increasingly larger blades to complete the 738 linear feet of inverted flush cutting into 36 inches of concrete. Despite a bitter pittsburgh winter, operators completed the job on time and within budget. ■

Beefing up the Bridge

The westbound bridge was built across the Tacoma Narrows in 1950, carrying commuters both east and west until the new bridge was completed 2007.

Safety is the key to a Washington State bridge retrofit.

In 1950, Tacoma, Washington was connected to the Kitsap Peninsula by the Tacoma Narrows Bridge. For 57 years, this four-lane bridge carried commuters both east and west across the narrow waterway. Today, the historic bridge is in the final stages of a retrofit to meet current safety requirements and carry travelers in one direction only.

The Washington State Department of Transportation (WSDOT) wanted to construct a sister bridge over the narrow waterway to separate traffic and ease congestion on the roadway to and from the peninsula.

Washington voters from several counties approved the construction in 1998. The new bridge was to be a landmark project with a center-span length of 2,800 feet, making it the longest suspension bridge built in the U.S. since the Verragano Narrows Bridge in 1964. Tacoma Narrows Constructors (TNC), a joint venture between Bechtel Corporation and Kiewit Pacific, was named general contractor and construction began in

The International Association of Concrete Drillers and Sawers Turns 13 in Spain September 2008 The International Association of Concrete Drillers and Sawers (IACDS) celebrated its thirteenth anniversary in grand style in Valencia, Spain in early May. The recently formed Spanish Association of Technical Demolition Drilling and Sawing (AEDT) hosted the delegates from around the world. In attendance were over 40 delegates from Austria, Australia, Belgium, Germany, Hong Kong, Japan, Liechtenstein, Luxembourg, Russia, Spain, Sweden, Switzerland, United Kingdom and the United States.

The two-day assembly provided International Association of Concrete Drillers and Sawers attendees with a broad range of cultural and artful entertainment as well as a conference packed with important industry information. The agenda covered issues ranging from internal financial matters to marketing analysis of the industry and creating better training programs.

AEDT is the newest country sawing and drilling association formed last year with assistance from IACDS member associations. Assisting countries in forming their own associations has become a common endeavor for IACDS. Assistance has been also provided to Italy, Poland, Russia and Slovakia and many of those members have attended IACDS meetings or hosted them.

In addition to helping other countries form their own associations, what else has IACDS been able to accomplish since its founding in 1995?

Even though the IACDS members only convene once a year, they can be quite proud of what their organization has accomplished. Two very important documents that were created, at the beginning with much

difficulty, have been revised and enhanced over the years and now are accepted quite well. They are the new “Basic Parameters for Concrete Drilling and Sawing Equipment” and the revised “Tolerances and Limits for Construction Drilling and Sawing.” The manufacturers of concrete drilling and sawing machines, in order to unify the parameters and allow better comparisons of hydraulic machines, drafted the parameters document. The tolerances document forms the preconditions for accuracy and/or limitations to differentiate the advanced capabilities of the professional cutting contractor.

The project to collect worldwide market data for sawing and drilling contractors continues even though there is some resistance by members to share the data or there is a lack of data to be collected. IACDS has been able to identify that the total number of contractors worldwide exceeds 10,000. Great strides were made at the May meeting to expand the number of countries reporting information, and it was hoped that this effort would gain wider acceptance for its merits and benefits to the industry in the future.

Delegates also discussed the industry’s need to educate architects,

First, second and third place diamond awards from 2007.

engineers and government officials about the advantages of concrete sawing and drilling and its many practical applications. IACDS is launching two new projects focused on reaching these specifiers. One will utilize the association website to create links of sawing and drilling job stories, categorized by job type that will be readily accessed over the Internet. The second is the development of a textbook geared toward specifiers at the university level. This textbook will delineate the benefits and capabilities of the sawing and drilling industry.

IACDS also received several presentations on insurance and the emerging polishing and finishing market. O’Brien presented a summary of the CSDA Insurance program in the U.S., and Jan Lemos informed the delegates about the successful insurance program they have in Sweden.

Two presentations were made by Antonio Zerolo of Anzeve (HTC distributor) and Alain Dupont of Husqvarna of the rapidly emerging floor preparation market. The current market for tools is estimated at Euro 200,000 (US$320,000) worldwide with an annual growth rate of 35%.

Plans were made for conducting the 2009 Diamond Award competition. IACDS has assumed the administration of the Diamond Award for concrete sawing and drilling. The German Association, for the past decade, has organized this event. It has been successfully held in conjunction with German trade shows, most recently Bauma. IACDS has assumed the administration of this award competition which will be rotated around the world. The 2009 Diamond Award winners will be announced at a press conference on Wednesday, February 4, 2009 at 10:00 AM during the World of Concrete. The World of Concrete show managers will actively promote this event on their website and in promotional literature. In addition, they have offered complimentary hotel rooms for the first, second and third place winners to attend the event and the show. IACDS will offer air transportation for the winners.

The first thirteen years of IACDS have been very productive as well thanks to the dedication of sawing and drilling professionals from around the world who have come together to provide a better future for the sawing and drilling industry. IACDS will celebrate its 14th anniversary

IACDS Diamond Award Competition Opens The International Association of Concrete Drillers and Sawers (IACDS) opened the competition for the 2009 Diamond Award. “The Diamond Award has continued to grow in influence since it was first introduced in 2000” said IACDS President Patrick O’Brien. “It has become an internationallyrecognized competition for sawing and drilling excellence involving planning, complexity, innovation, degree of difficulty and quality.”

Entries for the Diamond Award must be submitted online no later than October 31, 2008 at www.iacds.org/ diamondaward. A panel of international experts from the industry will judge entries based on criteria that include project description; machines and tools; complexity of planning and execution; innovative approaches that solved challenges; quality specifications and photos.

The top three winners will receive complimentary airfare and a three-night hotel stay in Las Vegas for two, courtesy of the Diamond Award sponsors. The sponsors are the World of Concrete, USA; Cedima GmbH, Germany; Diamond Products, USA; Hilti AG, Liechtenstein; Husqvarna Construction Products, Sweden; Hydro-Tec GmbH, Germany; Nestag AG, Switzerland; St. Gobain Abrasives, Belgium; and Tyrolit, Austria.

IACDS is comprised of eight country associations, including CSDA. O’Brien is also executive director of CSDA and will announce the top three winners at an award ceremony press conference at 10:00 AM on Wednesday, February 4, 2009, during the World of Concrete.

sories and techniques in surface prep are providing the csDA contractors with new market opportunities. the world of surface prep can be broken down simply into three categories (stock removal, coating removal and coating prep) with five different classifications of machines based on the methodology of the cutting action (grinders and/or polishers; planers; shot blasters, needle scalers and scabblers; chisel scalers and strippers; and saws). recently the csDA standards and specifications committee released a specification on polishing concrete. the csDA involvement in the creation of this specification demonstrates a commitment to developing industry accepted definition of a true polished concrete slab without major shortcuts to the claim of a polished slab.

A Safe Workplace is a Drug-Free Workplace

T

cally trained on how to make that determination.

Employee Education A drug and alcohol education program provides employees with information they need to cooperate with and benefit from a drugfree workplace program. Effective programs provide company-specific information, such as the details of the company’s policy, as well as general information about the nature of addiction; its impact on work performance, health and personal life; and help available for related problems. All employees should participate, and the message should be delivered on an ongoing basis through a variety of means, such as home mailings, displays, brown-bag lunches, guest speakers and sessions at new employee orientation.

4 0 | september.08

Employee Assistance A critical component of a drug-free workplace is providing assistance to employees who have problems with alcohol and other drugs.

Employee Assistance Programs (EAPs) are work site programs that provide problem identification, assessment and referral services for employees. They are effective vehicles for addressing poor performance that may stem from an employee’s personal problems, including substance abuse.

EAPs benefit employees and clearly demonstrate employers’ respect for their staff.

They also offer an alternative to dismissal and minimize employers’ legal vulnerability by demonstrating efforts to support employees. In addition to counseling and referrals, many EAPs offer services such as supervisor training and employee education.

At a minimum, businesses should maintain a resource file from which employees can access information about communitybased resources, treatment programs and help lines.

Drug Testing Some employers decide to drug test for a variety of reasons, such as deterring and detecting drug use, as well as providing concrete evidence for intervention, referral to

Industry Bits CSDA Issues CSDA Diamond Cutting Tools for ADA Best Practice

Russian Concrete Cutting Contractor Marks 15th Anniversary

The Concrete Sawing and Drilling Association (CSDA) has been the leading association for issuing standards, specifications and best practices for the sawing and drilling industry since its founding in 1972. CSDA provides vital materials for architects and engineers to work on a professional basis with sawing and drilling contractors. As part of its effort to achieve these goals, CSDA has developed a Best Practice entitled, CSDA Diamond Cutting Tools for ADA. The United States Government has issued a series of guidelines and regulations to establish a standard level of accessibility for individuals with disabilities. These guidelines are to be followed during the design, construction and alteration of buildings as required by regulations issued by Federal government agencies as a result of the Americans with Disabilities Act (ADA) of 1990. CSDA Best Practice CSDABP-005, CSDA Diamond Cutting Tools for ADA, provides a quick overview of the ADA standard and outlines the types of concrete cutting tools that could be employed to perform the tasks necessary to be in compliance with the standard.

For more information on the CSDA Diamond Cutting Tools for ADA Best Practice, contact the CSDA office at 727-577-5004 or go to the CSDA Website, www.csda.org, and click on the Standards, Specifications and Best Practices link on the right-hand side of the CSDA home page.

ICS® Announces FORCE4™ Initiative ICS has expanded the selection of FORCE4™ bars, chains and powerheads and reduced prices. “FORCE4™ is the next logical step in diamond chain evolution,” stated ICS President Jake VanderZanden. FORCE4™ is the newest development in diamond chain from ICS. Designed to be the strongest diamond chain on the market, the difference is visible: a much larger chassis provides 50% more tensile strength than standard diamond chain. The new lower prices combined with the addition of two bar lengths, 10- and 20-inch, three new chains, ProFORCE™ Premium L, Premium S and Abrasive and an 8 gpm power head make the FORCE4™ line comparable to the ICS PRO series in both selection and price, while 50% stronger. Other features include deep engagement drive links for straighter cuts and a patent-pending pitch design of the diamond segment that creates the optimal blend of weight and strength.

Headquartered in Portland, Oregon, ICS is a division of Blount International, Inc., a diversified manufacturing company with global distribution. For more information, call 800-321-1240 or visit www.icsbestway.com.

Hilti Introduces New Combihammer With a new 1700 watt motor, the Hilti TE 80 ATC-AVR is a very powerful combihammer. The TE 80 ATC-AVR makes light work of a wide range of demanding jobs including hammer drilling in the ¾-inch to 6-inch diameter range in concrete, masonry and natural stone, drilling through-holes up to 6 inches in diameter in concrete and masonry, and heavy chiseling work and drilling with high torque in wood and steel.

The active vibration reduction feature provides optimum operator protection and a high level of working comfort even during long periods of use. A mass damper system suspended on springs inside the casing absorbs vibration in the tool’s longitudinal axis while the grip, which is decoupled from the rest of the tool, efficiently absorbs even vibrational torque. Another safety feature is an active torque control, an electronic rapid cut-out system that disengages the tool drive system if the drill bit sticks and the tool starts to rotate too quickly, thereby providing additional operator protection. For more information,contact Hilti Customer Service.

Atlas Copco Construction Tools Introduces CC 2500 Hydraulic Demolition Attachment Atlas Copco Construction Tools LLC introduces the CC2500 to its line of conbi cutter hydraulic demolition attachments. The new attachment offers faster jaw replacement, enhanced stability and shorter cycle times.

For optimum application versatility, both universal jaws and steel-cutting jaws are available for the CC 2500. Opening to a width of 34.6 inches, the universal jaws are ideal for heavily reinforced concrete demolition, building demolition, secondary reduction and material separation. The steel-cutting jaws open 16.8 inches wide and are suited for steel structure demolition, secondary reduction and material separation. Both jaws deliver a maximum cutting force of 330 tons. The CC 2500 features a single pin jaw retention design that improves tool visibility for the operator, decreases the total weight of the unit, and drastically reduces the time required to switch between the different sets of cutting jaws. To further increase the convenience of on-site jaw replacement, the CC 2500 comes with a coupling and positioning system (CAPS) that keeps each set of jaws connected after they have been removed and facilitates refitting through a special guide system. The CC 2500 comes with easy-to-replace wear parts, including reversible blades that provide longer service life, and a host of other features designed to increase the durability and performance of the machine. For more information, contact the company at 413-746-0020.

So when I started my business in 2000, becoming a member of CSDA had already been decided. It was just a matter of establishing my company first. One year after setting up shop, I joined. Since then, I’ve enjoyed the friendships, information and programs made available to me through CSDA. The most important benefit of membership for my company has been attending CSDA functions.

The NEW WS 440 HF Wall Saw. Husqvarna’s new WS 440 HF is setting a new standard for electric high cycle wall saws. The saw is based on a totally new technology, which gives the saw increased power for fast and efficient sawing. The powerful, water-cooled electric motor generates 17 horsepower to the shaft, despite the fact that the saw only weighs 55 pounds. The 9,000 rpm permanent magnitized motor delivers 100% power to the blade while cutting concrete or steel.
