CASES

Splashat SkyCity Rooftop Pool Removal Aids Auckland Hotel Renovation

A

development plan for a luxury hotel and casino in Auckland, New Zealand, consisted of extra floors that include four VIP villas with gaming

areas and VIP salons. In order to add these extra floors, a rooftop swimming pool needed to be removed.

SkyCity is one of Auckland’s biggest hotels, with over 340 rooms

and views of the city’s harbor. One of the main draws of the hotel is the Sky Tower, a 328-meter-tall (1,076-foot) building that is the largest man-made structure in New Zealand. Visitors can dine in one of the tower’s restaurants or perform a 192-meter (630-foot) wire jump from the tower’s viewing platform. The VIP area development project was scheduled for completion in June 2011. This is so that the hotel will be prepared for a large volume of high-profile visitors arriving in September for the 2011 Rugby World Cup, an international tournament that features 20 teams and runs for two months.

The removal of the rooftop pool was scheduled for three weeks in February, and had to be done quickly to keep the project on track while keeping disruption of hotel operations to a minimum. The pool measured 13.3 meters (43.6 feet) long, 5.1 meters (16.7 feet) wide and had a depth ranging from 1.2 meters (3.9 feet) to 1.8 meters (5.9 feet).

The concrete walls and floor of the pool were 250 millimeters (9.8 inches) thick. The general contractor for the project, Hyline Construction Ltd. of Auckland, began searching for a contractor that could take out the concrete pool without causing large amounts of vibration and noise that would disturb hotel guests.

A1 Kiwi Cutters & Drillers Ltd., a CSDA member based in Auckland, was contracted by Hyline to remove the pool. The plan devised by A1 Kiwi Cutters and approved by Hyline, called for the walls of the pool to be cut into 16 sections using a wall saw with diamond blades. It was specified that none of the cut sections could weigh more than 2.7 tons due to capacity of the crane on site. Each cut section would have two 132-millimeter-diameter (5.2-inch) holes core drilled into it so that lifting straps could be attached, then the section could be removed by the crane. Before the final cut was made on each section, the piece would be rigged for removal. The floor of the pool was to be cut into 14 sections using a floor saw, and a similar method was used to hold the weight of the cut piece before the final cut and removal. A1 Kiwi Cutters was responsible for the provision of machinery, labor and slurry control during all the cutting and drilling processes.

The Auckland Skyline.

As the hotel was to remain fully operational during the work, wall sawing and diamond core drilling was the best choice. Wall sawing is much more quiet and efficient than demolition methods like jackhammering or the use of a wrecking ball. “This technique meant minimal disruption for the hotel staff and guests, as there would be less vibration, less debris and the cutting would not be as labor-intensive as breaking or wrecking,” said Penny Simons, co-owner of A1 Kiwi Cutters & Drillers Ltd. The cutting contractor worked closely with Hilti New Zealand Ltd. and used a DS TS20-E wall saw to perform the majority of the cuts. The first step was to wall saw the internal perimeter where the pool walls met the pool floor. The cuts were made 50 millimeters (2 inches) above the joint and were completed in five hours. It was then time to core drill the 132-millimeter-diameter (5.2-inch) holes for the lifting straps. Two holes were cored per section using a Hilti DD200 core drill. The final part of the pool job involved vertical wall sawing. The walls were divided into 16 pieces and measured to be no longer than 2.4 meters (7.9 feet) and weigh no more than 2.7 tons. The sections were rigged while the final cut was being made, then the piece was removed from the work area.

The process was repeated until all 16 sections had been cut free. This took six days to complete.

Once all of the concrete pool wall sections were removed from the work area, the cutting team began to mark out the floor of the pool for cutting and core drilled holes measuring 132 millimeters (5.2 inches) in diameter to attach lifting straps. An operator then used the floor saw to

of the slurry according to current legislation.

Control of the slurry and waste water was critical, as A1 Kiwi Cutters had to make sure that no waste leaked into the occupied hotel rooms on the floor below.

Due to the strict time frame applied to the whole project, time was of the essence. The hotel stood to lose a large amount of revenue if the new facilities were not available for the Rugby World Cup. In order to complete the job, A1 Kiwi Cutters had up to five operators on site most days. Mark Simons, director of A1 Kiwi Cutters & Drillers Ltd, oversaw the day-to-day management and organization of the team. Simons operated the wall saw while operators took care of the core drilling, floor sawing and slurry control. The pool was successfully removed in 16 days.

The main safety concern was the risk of pool sections falling before being removed.

This concern was overcome by the core drilling

The floor was cut into 14 sections weighing 2.6 tons each.

A Hilti DS TS20-E Wall Saw was used to perform the vertical cuts to the interior walls of the pool, while the cuts to the floor of the pool were made by a 35-horsepower Core Cut floor saw from Diamond Products. Hilti also supplied a DD200 core drill to create the picking holes for the crane rigging, while Husqvarna K1250 and K960 cut and break saws were also used for some parts of the cutting work. Slurry and waste material were collected using a WVD2002 twin motor wet vacuum from Numatic.

To cut and remove the rooftop swimming pool at the SkyCity Hotel, A1 Kiwi Cutters & Drillers Ltd used the wall saw to cut over 65 meters (213 feet) of cuts and a floor saw to perform over 100 meters (328 feet) of cutting. For rigging of the concrete pieces, the contractor core drilled over 140 holes before attaching to the crane and removing over 80 tons of concrete.

This is the standard outlined by the Saw Manufacturers Institute (SMI), Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI). Safety is the number one concern for each of these governing bodies and should be for any company.

Another important concern for concrete cutters, however, is how to get the best performance and greatest value from diamond tools.

Following is valuable information regarding the manufacture of diamond cores and cutter best practices. This information will help minimize the chance of core cracking, maintain safety and achieve the performance levels required for the job.

Laser cutting of the core is the most desirable manufacturing process because punching, milling and grinding can cause micro cracks and stress concentrations which increase the likelihood of core cracking.

Surface Grinding Rotary surface grinding removes surface imperfections such as raw material crown, scale and scratches. This helps to normalize and level the surface, reducing the possibility of core cracking from stress concentrations.

Leveling, Smithing and Tensioning Proper leveling, smithing and tensioning insure longer life, better performance and greater value for the contractor. Cores that are leveled and smithed flat will take and hold tension much longer than cores without. Tensioning, leveling and smithing will produce a core that runs true longer. Cores that run true will not wobble, heat up or fatigue nearly as fast. This can significantly increase core life and performance.

Equipment Care Keeping equipment in good working condition is critical to the safety of operators and the performance of diamond tools. Without proper maintenance and care of equipment, the life and performance of diamond tools is greatly reduced.

Machining the Outside Diameter Machining the outside diameter is critical for the core balance and concentricity. Cores must be concentric to ensure proper segment mounting and balance. This will also minimize the likelihood of hammering while cutting, especially if the segments are also outside diameter ground.

The following are best practices that will help minimize core cracking, increase performance and provide the most value from diamond tools.

Blade Shaft Bearings, Collars and Mounting Hardware Vibration is one of the main causes of core cracks and blade fatigue.

Maintaining blade shaft bearings, collars and mounting hardware are essential to reducing vibration and increase diamond blade performance by minimizing hammering.

Cooling of Diamond Blades Heat is also a main cause of core cracking and loss of tension.

Best Practices

Without tension, a diamond blade will not run true. It will contact

the sidewall, generate excessive heat and fail prematurely. Therefore,

In order to specify the correct diamond tool for the job, operators need to know the hardness of the material to be cut, the tool speed, the equipment power, the cooling method and the mounting type. The correct diamond tool for the application will increase diamond tool performance and reduce core cracking.

Operational Speed The operator must make sure that the diamond tool is run at the correct revolutions per minute (rpm) to get the best performance from the diamond tool and insure their safety and that of others in the work area.

Over speeding and over feeding a diamond tool will cause premature tool failure by increasing the amount of heat in the core and exceeding the mechanical properties of the steel. The following table shows the recommended rpm for 9,500 surface feet per minute (sfpm) blade speed.

a wet blade must have ample water to cool it properly. For a dry cutting tool, it is essential to operate within the blade manufacturer’s recommended tool speed and not to apply too much side load. These practices will help the blades operate within the design temperature and help to insure diamond blade performance and life.

The information provided in this article will help contractors keep their operators safe and maintain the profitable performance of diamond tools. Any questions or matters that require clarification should be directed to an official diamond tool manufacturer.

Contractor Demolishes Chimney at Incineration Plant

T

he project description was straightforward. Demolish a 150-meter-tall (492-foot) concrete chimney stack at a redundant incineration plant in Hong Kong so that the site could be cleaned up for reuse. However, the location of this particular chimney meant that it was not simply a case of bringing down the structure as quickly as possible, but bringing it down in a controlled manner that would not cause excessive noise or vibration. This was the challenge presented to one CSDA contractor.

to make his business a success and he had the energy to dive in. “From the beginning, I saw tremendous value in networking with industry leaders,” says Dvoratchek. “I sought knowledge, and the members of CSDA were willing to openly share their knowledge with me.” Hard Rock began to grow, as did his involvement with CSDA. He was able to implement the things he was learning into his business and share his own ideas with other members of the association’s Board and committees. This participation coupled with additional years in business helped him to gain much knowledge, forge important business relationships and form strong friendships—all things that can help any young business leader.

Ten Ways to Cut Fuel Costs

By Jack Lee

R

emember the good old days, when prices at the pump were below two dollars per gallon and usually stayed there? Well, the good old days are gone and today the world is a place where fuel prices seem to change by the hour. Now pundits speculate on living with oil prices running as high as $200 a barrel.

Many consumers have adjusted their lifestyles. Some try to drive less or have chosen to carpool, while others have traded their gas-guzzlers and opted for more fuel-efficient vehicles, including hybrids. For companies, the good old days meant simply having employees fuel up and head out to the job.

Little attention was paid to managing fuel. In the past year, the high price of oil is cutting deeper than ever into company profits, causing owners and managers to adopt a new fuel consciousness. Fuel management is a necessity.

Port of Tampico

Berthing Structure Removed with Wire Saw

A berthing structure required removal at the Port of Tampico.

W

hen the support pillars of a large concrete berthing structure at a major Mexican shipping port began to corrode, the authorities contacted a professional cutting contractor to demolish and

remove the platform. This work was to be done quickly, before the support pillars gave way and allowed the structure to fall into the water, which would create a hazard for passing ships.

The Port of Tampico is situated on the East Coast of Mexico in the state of Tamaulipas. Tampico was founded in 1554 and the city was declared an official deep-sea port in 1824. Today, the port has over 20 large docks in public and private shipping terminals, some of which can handle up to 50,000 tons of cargo that arrives by ship from the Gulf of Mexico. The total distance of these docks and terminals is over 4,000 linear meters (13,123 feet).

The decaying concrete berthing structure measured 6 meters long, 6 meters wide (19.7 feet) and stood 2.2 meters (7.2 feet) tall from the base of the port’s sea bed. The 0.7-meter-thick (2.3-foot) berthing platform was supported by eight 61-centimeter-diameter (24-inch) steel

After all nine specified sections of the concrete platform were cut and removed, the team from ADRA turned their attention to the 2-foot-diameter pillar structures. The task involved cutting and removing two pillars and transferring to land, where they were to be cut into three pieces to evaluate their internal structure. This would help the customer understand what failings had taken place and how to guard against further breakages on other structures. To remove the pillars, ADRA first used a diver to extract hard mud from around the bases. This eliminated friction between the soil and the pillars. The pillars were then extracted from the water by crane and laid out on land. Operators then used a Husqvarna K1250 gas-powered hand saw with a 16-inch-diameter blade to cut the pillars into smaller sections.

The main safety concern for Bracamontes and his team was the busy location and crumbling condition of the berthing structure. The extent to which the structure was decayed A Husqvarna CS2512 wire saw cut through the structure.

was not fully known, and so constant checking of its integrity was performed to guard

To begin the cutting work and prepare the wire saw setup, the contractor used a Hilti DD200 core drill with a 6-inch-diameter core bit from Husqvarna to create eight holes 0.7-meters (2.3feet) deep in the concrete platform. These holes would allow the diamond wire to pass through to set up runs for the wire saw and allow crane straps to be fastened around the sections once cut free. The core drilling of the berthing platform took one operator eight hours to complete. A 5,500-watt generator was used to supply power while water was supplied by a submergible pump with a 0.5-inch hose.

Once the structure had been core drilled, the cut lines for the sections were marked out and the wire saw was set up.

The Husqvarna CS2512 unit was anchored to the concrete and pulleys were set in place to create the wire runs. Power was supplied by a 125-kilovolt amperes generator and two electric pumps connected to one hose provided water to cool the wire during cutting. A diver was sent into the water to pass the wire around the underside of the structure, and also to inspect the structure and its support pillars. If any rebar was found to be obstructing the diamond wire run, the diver would return to the water immediately and remove the rebar with a cutting torch.

The contractor made a cut 6 meters (19.7 feet) in from the edge of the 0.7-meter-thick (2.3-feet) platform to get the first concrete section free. The first piece to be cut free weighed 15 tons and was removed by a 40-ton crane. Wedges were set in place as cutting progressed, and after the first section was removed, the remaining structure was inspected for stability.

This process was repeated for each of the nine concrete sections removed. It took the wire saw five hours to cut free one section.

mined that PPE is required, the issue arises over who will pay for it—the employer or the employee. In an effort to finally clarify who pays for PPE, OSHA began rule-making in 1999 which resulted in the ruling that took effect in 2008. The ruling adds a new subpart for each industry sector subject to the rule.

For general industry, the new rule is designated as 29 CFR 1910.132(h) – Payment for Protective Equipment. This subpart defines the new clarifications regarding payment for PPE. Importantly, while Section 1910.132 generally relates to PPE, there are other OSHA standards that specifically require PPE, including the blood-borne pathogen standard, the grain handling standard and a host of standards that are specific to regulated airborne contaminants such as lead and asbestos.

The regulation generally requires that all protective equipment used to comply with Section 1910.132, including PPE, must be provided to employees at no cost to them.

According to the new guidance document, the employer must provide the following PPE at no cost to the employee if used to comply with an OSHA standard: •

James Bond Test™ MK III Developed By James Instruments James Instruments, Inc. has developed the James Bond Test MK III test unit for measuring the bond strength, tensile strength and adhesion strength of concrete, asphalt, tile, concrete repair or other overlay material by the direct tension or pull-off method. The test unit can be used to verify the quality of the material being tested as well as determine the adhesion strength of shotcrete, tile, epoxies, paint and other repair materials, mortars or coatings. The test involves bonding a circular steel disc to the surface of the material being tested by means of an epoxy resin adhesive. A controlled tensile force is then applied to the disc and failure will occur at the weakest point—either in the host material or in the bond between overlay and host material. The new tester features two calibrated gauges that display the maximum load and mechanical damping and has an adjustable alignment plate with built-in leveling facility for both vertical and horizontal pulls. For more information, visit www.ndtjames.com or email info@ndtjames.com.

Concut, Inc. Announces New Double-Life Wall Saw Blade

Hilti Introduces New Gas Saw Floor Cart The new Hilti DSH-FSC gas saw floor cart is designed for small cutting jobs requiring the flexibility of a hand held gas saw and the precision cut and performance of a larger dedicated floor saw. The cart is compatible with Hilti DSH 700 and DSH 900 gas saws.

The gas saw floor cart is made of heavy duty steel construction and is supplied complete with a gravity feed water container that allows the cart to be portable while still providing the dust suppression needed to help contractors meet local ordinances or other requirements. For more information, contact Hilti customer service at 800-879-8000 in the U.S., 800-461-3028 in Canada or visit www.us.hilti.com in the U.S. or www.hilti.ca in Canada.

Concut, Inc. is pleased to introduce the new WS-MAX5 wall saw blade. This unique blade features laser-welded segments that are .800-inch tall—twice the height of conventional blade segments. These tall, sandwich segments are designed to maintain their width and to extend blade life to approximately twice the normal expected life. Since the WS-MAX5 has a wide .225-inch segment (matching the thickness of standard diamond chain), operators can avoid jamming and side clearance problems. The blade is also available in .187-inch and .250-inch versions. For more information, contact Tom Monaghan at 800-243-5888 or email tom@concutusa.com.

New Stihl Cut-Off Saw with Water Control System The new Stihl TS 420 A cut-off saw comes with an electronic water control (EWC) system for wet-cutting. After starting the 4.4-horsepower cut-off machine, the system can be activated with the push of a button. The plus and minus buttons allow the operator to regulate water flow for optimal dust suppression while keeping a hand firmly on the handle of the 22.3-pound saw.

The EWC system can use up to 50 percent less water than conventional systems depending on the cutting job and operator technique. A memory function stores the last water setting after the unit is turned off, eliminating the need to readjust the water flow. Water flow stops once the TS 420 A reaches idle speed and begins again when the throttle is engaged.

The TS 420 A can cut concrete to depths of 4.9 inches at a speed of 9,000 rpm. For more information, visit www.stihlusa.com or call 757-486-9100.

The unit can reach depths of up to 16 inches in concrete and features a laser-positioning system and a 4-wheel drive survey encoder to help mark targets. The unit has also been designed to be water resistant and dust proof (IP-64). The StructureScan Mini system has a center frequency of 1,600 MHz and weighs 3.3 pounds.

Bosch Introduces GLL2-40 Cross-Line Laser

Seal/No Seal Group Supports Research Efforts The Seal/No Seal Group represents the pavement industry, and its members are committed to quantifying the long-term effectiveness of joint sealants in concrete pavement. The group has developed a committed and active member base, willing to work together to advance the industry, and engaged with key industry associations including the Concrete Sawing & Drilling Association. The group has established a website that is used to communicate industry news, committee research findings and other information in support of the industry.

Other accomplishments for the group include having four state DOTs conduct evaluations of their existing seal/no seal test sections, partnering with roadway owners to construct 10 new sealant test sections and hiring the Texas Transportation Institute to conduct research on the effects of joint sealant condition on moisture infiltration and erosion potential. The group also worked with Purdue University to support research efforts to search for the cause for premature joint deterioration.

For more information about the Seal/No Seal Group, call Scott Eilken at 708-728-1895, email info@sealnoseal.org or visit www.sealnoseal.org.

Up To 16” Cutting Depth

The Bosch GLL2-40 is a cross-line laser designed for all professional interior jobsites up to 30-feet. The compact unit projects lines independently or together for various types of building construction leveling and alignment applications with 0.125-inch accuracy.

Weighing eight-ounces, the GLL2-40 is less than two inches wide and less than four inches in length and height.

The unit can be used to evenly mark cutting lines or set accurate core drilling points. A single button control allows the selection of horizontal, vertical, cross line or manual modes of operation. A leveling system locks the pendulum when the GLL2-40 is switched off, allowing all parts of the unit to be protected during transport.

An over-mold construction coupled with a recessed window ensure against damage from water and dust. The unit also includes a detachable floor and magnetic mount that allows full rotation. The mount is equipped with a 0.25-20-inch or 0.625-11-inch tripod mounting thread for additional mounting options. For more information, visit www.boschtools.com or call 877-267-2499.

Networking at the Annual Convention and Seasonal Meetings

Specifications, Standards, Tolerances and Best Practices

The number one benefit for members has always been the opportunity to network with cutting professionals at the annual convention and seasonal meetings. This networking provides opportunities to forge new relationships and learn from other experienced professionals.

Specifications, Standards, Tolerances and Best Practices are available for all types of cutting disciplines. Twenty-four documents have been developed and new ones are always in production.

CSDA Training

Members can market their company with How to Market Your Concrete Cutting Business and make presentations with the Diamond Advantage Seminar Planning & Presentation Manual. Four-color brochures and flyers are available for members to promote their business to customers and are easily personalized so members can avoid the cost of developing their own.

Over 2,000 members have graduated from more than 20 classroom, hands-on and online training programs: Cutting Edge, Slab Sawing & Drilling, Wall Sawing, Wire Sawing, Operator Certification, OSHA Construction Safety and Estimating. CSDA offers online training at www. csdatraining.com for those not able to afford the time or the money to send operators to remote classes. Owners/managers can monitor testing, scoring and documentation.

Concrete Openings Magazine

Concrete Openings (www.concreteopenings.com) is the only professional magazine dedicated to concrete cutting with a circulation of 16,000 per issue. Members can advertise at significant discounts and the opportunity to have their job stories reach over 7,000 architects, engineers, general contractors and government officials.

CSDA Insurance Program

The CSDA Insurance Program offers members coverage that includes Workers’ Compensation, auto, comprehensive general liability, environmental pollution, professional liability, equipment, Employment Practices Liability (EPL) and other lines specifically geared for the concrete cutting industry.

CSDA Website

The CSDA Website at www.csda.org contains a wealth of information available 24/7 in the “Members” section. The online discussion boards provide members a forum to discuss technical issues, sell equipment, hire employees or any other relevant topics.

CSDA Safety Resources and Toolbox Safety Tips (TSTs)

The 230-page CSDA Safety Manual, CSDA 57-page Safety Handbook and five safety DVDs are designed specifically for concrete cutters and are available to members at a significant discount. TSTs can be used in employee safety meetings and can be an important part of your company’s safety program. New TSTs are released every quarter.

Roundtables

The roundtable sessions at the annual convention and other meetings give members a chance to share their wisdom and acquire additional knowledge. Information gained during the roundtables gives members new ideas to implement within their companies and can save them money.

FREE World of Concrete Registration

Members receive free registration and reduced seminar fees for the industry’s annual exhibition of concrete-related equipment and supplies.

Mentor Program

New members can receive personalized assistance from a current CSDA Board or committee member during their first year of membership.

Representation with Governmental Organizations

CSDA has formed an Alliance with OSHA to advance the safety of cutting contractors. This partnership includes issuing Best Practice and Toolbox Safety Talk documents, joint exhibitions at trade shows, review of safety materials and roundtables. CSDA also actively participates with NIOSH on field testing.

Discount Programs

CSDA offers its members exclusive programs for insurance and online training, plus discounts on freight services, credit collection services, drug testing and safety services.

Cooperation with Industry Associations

CSDA is a founding member of the International Association of Concrete Drillers and Sawers (IACDS) and works with other associations around the globe to promote concrete cutting and the sustainability of concrete as a building material.

CSDA Next Generation Group

The CSDA Next Generation group is made up of members and nonmembers age 45 and under. The purpose of the group is to continue to grow the association while serving the needs and wants of the younger generation with the goal of continuing the excellence of the Concrete Sawing & Drilling Association. The group meets during the seasonal meetings, at the annual convention and at the World of Concrete.

Husqvarna’s new electric wire saw, the CS 10, uses components from the WS 440 HF or the WS 482 HF electric wall saws to create a powerful and flexible saw system for cutting through larger concrete structures.

The ability to use a wire saw and a wall saw interchangeably means increased efficiency and a highly cost-effective system. The CS 10 can be easily coupled to the wall saw’s operating unit, track and power supply so switching between the two saws is quick and easy. The saw unit has the option of mounting on either side of the wall saw track and the wire can be rotated in both directions, making it more flexible. The variable wire speed takes into account wire type and material to be cut, resulting in optimal performance.

The CS 10 wire saw is easy to maneuver and is controlled by a remote control which allows the operator to operate the machine easier and allows greater freedom to move around the work site. The system can be used for all types of wire saw jobs including foundations, bridges and thick walls.

Wire saw and a wall saw in a single system.
