Concrete Cutter Helps Prepare for World Trade Center Memorial Site
he horrifying events that took place on September 11th, 2001 will forever be etched in the memories of the people of New York City, the people of America, and those around the globe
who witnessed the tragedy. Now the city moves forward with hope as Ground Zero is transformed into a memorial site, including the construction of Freedom Tower. Since 2007, CSDA member company J. P. Hogan Coring & Sawing Corporation have been involved in the demolition of the World Trade Center slurry wall, that will make room for the new transportation hub, Reflecting Absence memorial, visitor orientation and education center and Freedom Tower. The memorial will also include the ‘footprints’ of the former twin towers as recessed pools, and will be surrounded by plant life and quiet public spaces at street level. The design for the memorial was chosen as a result of an international competition for architects, with New York’s own Michael Arad the winner.
J. P. Hogan cored over a thousand picking holes on the slurry wall.

Regular readers of Concrete Openings may remember the March 2002 issue that covered another CSDA member’s work at Ground Zero. Engineered Concrete Removal (ECR) was also involved with the slurry wall, creating exact openings for tiebacks. The J. P. Hogan team has also been there since the beginning. When the towers fell, their light towers helped illuminate the way for rescue teams and during the clean-up stage they drilled tieback holes that held back the river. J. P. Hogan were approached by the general contractor, Phoenix Constructors (a joint venture between Fluor, Skanska, Bovis and Granite Construction), to cut and remove the damaged 1,000-foot-long, 50-foothigh, 5-foot-thick slurry wall. The decision was made to remove the slurry wall to make way for the new construction because of the heavy damage sustained on September 11th, and it’s proximity to the 1 and 9 Subway and Port Authority Trans-Hudson (PATH) trains. The slurry wall is located on Veasey Street, between Church and West Street in New York’s World Financial Center. After consideration was given to various cutting and demolition methods, wire sawing was chosen in order to maintain the structural integrity of the slurry wall during the demolition process, as Gene Kelley of Granite Construction explains, “ The bathtub slurry wall has some unique aspects with limited access for conventional demolition methods, so it made good sense to use diamond wire sawing to remove the required sections.” Given the history of the site, a great deal of preparation was performed to identify actual and potential hazards that would compliDemolition of the slurry wall will make way for the new construction.

cate the job. A PATH station resides on the other side of the slurry wall, therefore J. P. Hogan had to take extreme care to stop slurry from spraying onto the live high-voltage tracks. In addition, a portion of the wall was heavily damaged by the fall of the twin towers so much care had to be taken to avoid the wall from breaking up during the demolition. Also, the team had to wait for the area to be excavated by Bobcat skid steers as each phase was completed. Blasting at nearby sites and other potential seismic events complicated the removal process. “We hope for the best, but prepare for the worst,” says John Hogan. “We have a comprehensive safety plan in place and all of J. P. Hogan Coring & Sawing Corporation’s operators are required to complete multiple safety classes.” These classes include a ten-hour OSHA course, confined space safety training and regular toolbox meetings, among others. However, when working on such a busy and highly-visible job site, extra precautions have to be taken. The Port Authority of New York and New Jersey safety courses included many topics including electrical hazards, proper use of Personal Protective Equipment (PPE), but also covered subjects such as how to react if a suspicious package was discovered, and evacuation procedures in the event of another terrorist attack. It was imperative throughout the course of the work that equal attention was paid to both these dangers, and those faced everyday by concrete cutters. For example, the Diamond Products remote-controlled wire saws used on the project were powered with 120 hp, V-6 gasoline engines, and the wire traveled at an average speed of 88 feet per Diamond wire sawing was used to perform the cuts.

Slurry Walls Slurry wall construction was used to construct the bathtub that surrounded most of the World Trade Center site. A slurry wall is a reinforced-concrete diaphragm wall used to build tunnels, open cuts and lay foundations in areas of soft earth close to open water, or with a high ground water table. Slurry walls are typically constructed with a set of guide The cutting team have removed over 11,300 metric tons so far.

needs of the growing population. Therefore, four lines with a total of 80 kilometers are planned to extend the reach of the system to more outlying areas of Monterrey. As part of the ongoing extension work, general contractor Grupo Garza Ponce approached CSDA member ADRA Tecnologia en Servicios SA de CV to help with a unique problem. It was discovered that during the construction process a structural oversight was made regarding the concrete quality of one of the main support columns on Line 2, part of which was still under construction. ADRA’s project was to cut the last four meters at the top of the column, approximately eight meters in height, so that the existing concrete could be replaced with a stronger, more robust alternative. The cutting was scheduled to take place overnight, with Raul Bracamontes’ team constricted to one night’s work for the completion of their project. The column was located between two of the major avenues of Av. Universidad and Nogalar in Monterrey, and traffic management in the form of orange flag holding personnel were employed to warn approaching drivers of the works. Alternative methods for the cutting of the concrete were reviewed, but ADRA felt in order to maintain the structural integrity of the support column and complete the work within the required time frame, that

diamond wire sawing would be the preferred process rather than the use of jack hammers or hydraulic equipment. In consideration of the amount of concrete to be removed once cut, two cranes were employed. A 40-ton crane was used to aid the cutting team with their range of maneuvers, and a 160-ton crane was utilized to remove the large piece from the support column. ADRA’s first task was to bore a 2-inch-diameter hole that would allow the insertion of a 1-1/2 inch 92 steel bar. The installation of this rebar helped to hold the piece of concrete after the cutting was complete. By using the maneuverability of the 40-ton crane and one basket, the cutting team were able to position two water drums holding 200 liters each, one Perello submergible 0.5 hp pump and the core drill with associated extensions in order to create the hole. Power was supplied by an 8,000-watt gas generator located at the base of the column. The wire cutting equipment was set up at the column, and three meters of large steel piping was adapted to provide support for the pulleys. Again, the range of movement allowed by the 40-ton crane proved to be invaluable when setting up the equipment, the only drawback being that these maneuvers could not be executed at a fast pace. Activities like adjusting the pulleys and setting the water supplies

and steel wedge were time consuming and ate into ADRA’s already limited time scale. The supply of water to the working area proved to be an issue in itself, for although Bracamontes’ team had four drums containing 200 liters each on site, the supply point for refilling was several kilometers away. In addition, due to the work taking place at night, the cutting team had to ensure the working area was well lit to enable the cut to be as precise as possible. The 8,000-watt gas generator provided the power for the main lighting, with many of the cutting team also using hand lamps. From the halfway point of the cut, the 160-ton crane took the weight of the piece being removed and held it for approximately four hours until the cut was complete.

extremely hard to ensure it was a great success. This confidence and ability to take on new challenges helped ADRA when being considered for these works, putting them in good standing against other companies who specialize in the field of concrete cutting and drilling. Since the success of this particular project, Bracamontes is now being approached by Grupo Garza Ponce for further cutting jobs on the Metro system as ADRAâ€™s reputation continues to grow.

Did You Know? Hydroelectric Power Hydroelectric energy is produced by the force of falling water. The ability to produce this energy is dependant on two main factors; the availability of water flow and the height from which it falls. Potential energy accumulates as water builds up at the dam wall, which is transformed into mechanical energy as water rushes down the sluice and strikes the rotary blades of the turbine. As the turbine rotates, so do electromagnets that generate electrical current in stationary coils of wire. The last stage of the process is to run the electrical current through a transformer, where the voltage is increased to enable it to be transmitted long distances via power lines. Hydroelectricity accounts for approximately 19% of the worldâ€™s source of electricity, and over 63% of electricity from renewable energy sources. Pumped storage hydroelectricity produces electricity to supply high demands by transferring water between reservoirs at different elevations. At times of low electrical demand, excess generation capacity is used to pump water into the higher reservoir. When there is higher demand, water is released back into the lower reservoir through a turbine. Hydroelectric plants with no reservoir capacity are called run-of-the-river plants, since it is not then possible to store water. Tidal power plants make use of the daily rise and fall of water due to tides. However, such sources are highly predictable and if conditions permit, construction of reservoirs can also be dispatchable to generate power during high demand periods.

Once the access holes were complete, the wire was fed through two holes and around two exterior pulleys and back to the Plattner GS 30-180 wire saw. This operation was repeated three more times to complete the perimeter cutting of the opening. Each fourfoot by nine-foot cut took just over an hour. The wire saw was a 480-volt, three-phase, 30-kW drive unit with a wire magazine capable of storing 58 feet of diamond wire. The magazine type wire saw allowed the cut to be made without moving the equipment during the cutting operation while an omni- directional pulley system enabled the wire saw to cut from any direction, thus reducing setup time.

method of removal for two separate hatch openings in the basement and main floors. The plug was pulled approximately three feet out of the opening and then cut into smaller pieces to fit through the basement and main floor hatch openings. A total of three sections were removed from the opening. To complete the opening, a larger, surface perimeter cut was made, using a Diamond B hydraulic Pentruder wall saw. This cut was required to create a pocket around the exterior of the new opening for a special steel hatch that was placed on the exterior opening to seal off the scroll case during operations. The exterior cuts were 24 inches deep and 8 feet long. The wall saw was then used to make an inside perimeter cut, 24 inches in from the

Durban Harbor Widening Project CSDA Contractor Helps Ease Congestion at South Africaâ€™s Busiest Seaport Durban is the third most populous city in South Africa, forming part of the eThekwini metropolitan municipality. It is the largest city in KwaZulu-Natal, famous as the busiest port in Africa. The Port of Durban (formerly known as the Port of Natal) is one of the few natural harbors between Port Elizabeth and Maputo, and is located at the beginning of a particular weather phenomenon which can cause extremely violent seas. These two features made Durban an extremely busy port of call for ship repairs when opened in the 1840s. The Port of Durban is not only the busiest in South Africa, but also the busiest container port in the Southern Hemisphere.

Due to increasingly high congestion levels at Durban Harbor, the decision was made by South Africaâ€™s National Ports Authority (NPA) to widen and deepen the harbor entrance. The aim of this particular project was to alleviate congestion by reintroducing a bi-directional flow of harbor traffic. Prior to this project the movement of vessels in and out of the harbor was restricted to one direction at a time, causing delays and disrupting the local economy. South African infrastructure company Group Five, in partnership with the Belgian company Dredging International, were awarded the R1.8 billion contract (approximately $218 million) to expand the entrance Aerial view of the Durban Harbor widening project.

approached by Subtech Diving, a specialist diving company who had been appointed by the client as the marine contractor for the project. The task facing Subtech was the demolition of the harbors tug jetty and ferry wharf, along with other specialized diving and marine solutions. Holmes Sawing & Drilling were considered due to their excellent reputation, as Andrew Holmes explains, “We have been a leading contractor in the cutting industry for the past 13 years, and our track record for completing difficult and highly technical projects convinced the client to negotiate the works with us.” After considering alternative methods, including the use of excavators with demolition hammers, Subtech made the decision to use diamond wire sawing. By utilizing this method, large sections of concrete could be cut and removed from the harbor itself, while ensuring that debris would be limited. The aim was to avoid debris falling into the water, as this would necessitate the divers having to clean up the rubble. However, as the job progressed it became necessary to revert to percussive demolition as the risk to the divers when moving each 720-ton section and releasing the lifting frame posed too high a risk as winter approached.

Clearly, the stakes have risen, but the rewards for success are high. According to the VIP Forum, a Washington DC-based marketing research firm, data gathered from the Federal Reserve’s Survey of Consumer Finances indicates that most millionaires own private companies. In fact, 49% of individuals maintaining a net worth between $1 and $10 million own their own business. The percentage almost doubles at higher levels of wealth. For individuals with a net worth between $10 and $50 million, 77% own their own businesses, and for those with a net worth above $50 million, a staggering 89% are business owners.

and protect it.
Successful Planning Approaches Successful business owners generally take a process- or planningdriven approach to decision-making for their businesses. There are four phases of a strategic planning process: Phase I–Strategy Analysis; Phase II–Strategic Alternatives; Phase III–Strategy Implementation; Phase IV–Strategy Monitoring and Control. Making the decision to keep or sell a business requires the same detailed approach. Starting with an objective advisor is critical to gaining an objective recommendation for the ownership transition strategy to be ultimately implemented.

a preference as to which transition strategy is selected.
For a privately-owned business with a net worth of $20 million and a growth rate of 7.2% per year, the cost of procrastination is more than $75,000 per month. Given that the impact of the estate tax rate and costs may reduce shareholder value by nearly 50%, the need to map out an appropriate ownership transition strategy has become more crucial than ever before. Otherwise, the surviving children in the business will bear the blame and possible litigation. “My brother killed the family business” is a comment often made when dad and mom failed to develop and communicate a quality plan. In reality, how can a business survive when it pays nearly 50% of its value in taxes every generation simply to “stay in the game”? As staggering as the estate taxes are to the competitive dynamics of the business, non-financial, family issues are the primary reasons the business fails to make it to the next generation.
Thanksgiving Dinner It’s about more than the business—it’s about the family. This comment is often heard when interviewing the CEO and spouse of privately owned companies. Most families know they will have plenty of wealth; the big question is whether the business and wealth can be transferred in a way that the family still wants to get together for Thanksgiving dinner. These same issues arise within families regardless of the amount of wealth involved, so the “what” issue is less crucial than the “how”.
Where Do I Go from Here? Clearly, the fundamentals of business planning have changed. Business owners must include comprehensive succession and wealth management planning into their overall strategic business plan. They need a financial architect who can provide a customized blueprint—one that integrates their business, family, financial and non-financial issues. Strategic positioning of the privately owned business and wealth requires a commitment to a holistic process with the intent to align and communicate business and family objectives. Financial planning for the business owner requires a strong grasp of the business and family dynamics. A financial planner backed by a team of skilled advisors can bring objectivity to the process of defining the optimal outcomes for the business and family, reviewing all options, identifying the pros and cons of each, and determining if the recommendations are sound based on the specific situation and goals. This approach will help accomplish two key objectives: keeping more of the hard-earned dollars in hand and keeping the peace at the family Thanksgiving table. Joseph J.

Court ruled that absent a special relationship between the manufacturer of the cable and the employer of the dead workman, which would make the manufacturer only vicariously liable for wrongful acts of the employer, there was no right of indemnification on the part of the manufacturer. A special relationship is one when the law imposes certain obligations such as an employer/employee relationship or parent/child relationship, whether it is a duty on the part of the employer or parent to protect third parties from harm and the failure to do so will recreate liability on the part of the employer or parent. As the manufacturerâ€™s liability related to its own wrongdoing, it failed the test of common law indemnity. Contractual indemnity is as it sounds. When one party agrees to hold another party harmless from a particular type of loss or damage, as described in a contract between the parties. Many people identify this type of agreement as a hold harmless agreement. Indemnity agreements are

The Provision of PPE and Training Currently, numerous OSHA standards require employers to provide employees with specialized training and/or PPE to protect employees from occupational exposure to hazards. For example, the Lockout Tagout Standard, 29 CFR 1910.147, requires the employer to train employees on the control of sources of hazardous energy. Similarly, nearly all of OSHA’s toxic substances standards (e.g. hexavalent chromium, vinyl chloride, asbestos, etc.) require employers to train employees who are or may be exposed to the substance in the workplace.

Commission reasoned that, unlike the construction asbestos standard, the lead standard required respirators for each affected employee. Most recently, in 2007, the Review Commission affirmed twelve citations issued to General Motors under the LOTO standard’s training requirement, 29 C.F.R. 1910.147(c)(7)(iii). The Commission held that, unlike the construction asbestos standard in Ho, the LOTO standard required training for “each employee.” Thus, the Commission held that the LOTO standard imposed an employee-specific duty on employers to train each individual, and OSHA could issue citations under the LOTO training standard on a per-employee basis.
Proposed Amendments In its preamble, OSHA cited the Review Commission’s “magic words” analysis as its basis for proposing revisions to several training and PPE requirements. 73 Fed. Reg. 48,340. OSHA takes the position that it has always interpreted training and PPE requirements, regardless of the precise wording of the standard, to be enforceable on a per-employee basis. However, in light of the Review Commission’s decisions that have vacated citations based on linguistic variations, OSHA proposes to revise the following standards to specify that “each employee” is to receive training and/or PPE where required. OSHA has added general provisions, 29 C.F.R. 1910.9, 29 C.F.R. 1915.9, 29 C.F.R. 1918.5, and 29 C.F.R. 1926.20, that codify the employer’s duty to provide PPE and training to each employee where required under any standard.

FORCE4™ is the newest development in diamond chain from ICS, designed to be the strongest diamond chain on the market. The difference is easy to spot: a much larger chassis provides 50% more tensile strength than standard diamond chain. The 633F4 gives the superior strength of FORCE4™ the portability and ease-ofuse that is a trademark of ICS gas-powered concrete chain saws. Based on the popular 101 cc, 6.5 hp 633GC concrete chain saw, the F4 package comes standard with a FORCE4™ sprocket, FORCE4™ 14- or 16-inch guidebar and ProFORCE™ diamond chain. The 633F4 features slurry-resistant crankshaft sealing, dust-proof air filtration and water-resistant electronic ignition. A wet cutting system that can be supplied by a standard garden hose reduces hazardous dust while a built-in WallWalker™ provides leverage to reduce fatigue and extend chain life. The 633F4 is able to plunge cut up to 16 inches deep and make perfectly square openings with no overcuts. For more information, call 800-321-1240 or go to www.icsbestway.com.
K2 Diamond Introduces the K2-4000 Self-Propelled Concrete Saw K2 Diamond will introduce a new line of water-cooled gas and diesel concrete saws at the World of Concrete. The K2-4000HY and 4000KB are the latest additions to the K2 Diamond concrete saw line. The new K2-4000HY features a Hyundai 1.6L 4 cylinder water cooled engine with 48 hp output. The low vibration water cooled engine, meets all California and Federal emission standards. The new K2-4000KB features a Kubota 1.5L 4 cylinder turbocharged, water-cooled engine, with 44 hp of output. Kubota’s new E-TVCS (Three Vortex Combustion System) provides clean, quiet, low vibration power. Both saws have a new on-board, computer-controlled, fuelinjection system which monitors and adjusts fuel flow for optimum

power at all operating settings. In addition, the computer provides up-tothe-minute diagnostics of all engine operating conditions with the touch of a button. The saws also feature new T-handle traverse control, variable plunge speed control, improved controls for one-handed operation, 3-position handlebar adjustments and improved throttle control via a power actuated system that holds the power setting at the preciselydesignated rpm. The blade guard is equipped with flexible water tubes that ride directly on the blade, significantly decreasing the amount of water mist and therefore decreasing the amount of water necessary. This produces less slurry while providing maximum blade cooling and lubrication. The water system also provides superior blade cooling at all depths. Right or left mounting of the blade guard is simple with the quick release control and spade mounts. The K2-4000 series also has a front and rear pivot system that makes the saw extremely maneuverable for the operator on any job site. The Eaton Model 6 hydrostatic transmission is coupled to a K2 engineered differential lock transmission. This differential lock transmission provides positive tracking during cutting on slippery surfaces and provides travel speed from 0-220 FPM in forward to 0-100 FPM in reverse. Another feature of the transmission is that it can be disengaged from the axle to allow the saw to be pushed manually. The K2-4000 also features removable panels for maintenance accessibility, an electro-hydraulic pump that is maintenance free, a 7 V-belt drive system, ensuring maximum power transfer and a fullyenclosed, sealed blade shaft with continuous oil bath lubrication system. For more information, call 800-539-6116 or go to www.k2diamond.com.

CSDA 2009 Annual Meeting Notice The annual meeting of the members of the Concrete Sawing and Drilling Association will take place at 11:00 AM on Saturday, March 7, 2009, at the CasaMagna Cancun Marriott Resort, Cancun, Mexico, for the purpose of receiving reports, transacting business and electing officers and directors.
Atlas Copco Introduces SB 302 Hydraulic Breaker Atlas Copco Construction Tools, LLC introduces the SB 302, the first mid-range addition to the company’s new generation of SB hydraulic breaker attachments. The breaker is ideal for demolition, road construction, trenching, landscaping and secondary breaking. With a design focused on higher efficiency, the SB 302 offers a high power-to-weight ratio and delivers a maximum impact rate of 1,380 blows per minute, a 48 percent increase over its predecessor. The 670 pound breaker is suitable for carriers in the 4.5 to 9 metric ton weight class, and requires oil flow of 13.2 to 21.9 gallons per minute at a pressure range of 1,450 to 2,175 psi. The breaker’s slimline design allows for better operator visibility and easy positioning in confined spaces such as during indoor demolition and narrow trenching. A new hammer mechanism with recoil dampening is incorporated, reducing vibrations by up to 53-percent compared with previous SB models and helping to ease stress on man and machine. Noise levels have also been lowered by 5 dB(A). Routine maintenance of the SB 302 is simple thanks to a limited number of moving parts and a replaceable floating bushing. For added equipment reliability, the SB 302 features a built-in pressure relief valve as standard to protect the breaker from exceeding recommended operating pressure. The accumulator has been cast into the main body of the breaker for a more rugged design, and uses a new charge valve, that is now flush with the accumulator cover for optimum protection. These new features eliminate the action of unbolting the accumulator when re-sealing the breaker and the need for constant charging of the accumulator. The SB 302 is covered by a limited three-year warranty. For information, contact John Vogel at 413-746-0020 or by email at firstname.lastname@example.org. 5 2 | de ce mber.08

The opportunity to interact
In my life and my business, I place a high value on integrity. It is of utmost importance that my actions, both personal and business, are consistent with this value. To me, this means I provide a safe and respectful place for my employees to work. It means I provide my employees with high quality equipment and supplies, as well as the training necessary for them to perform their work safely, efficiently and professionally. This in turn, allows me to provide service to my customers that is high quality and fairly priced. My membership in CSDA supports my vision of a company run with integrity through it’s many programs, including operator

This allows for the exchange of information pertinent to our industry, as well as providing a chance to have some fun. The mentoring of new business owners and the camaraderie of veterans is crucial to the advancement of our industry. Joining CSDA has been one of the best decisions I’ve made for my business.
