ohn F. Kennedy Airport is one of the busiest airports in America. Annually, it handles 48 million passengers and is the leading freight gateway to the country in terms of shipment value. The 14,572-foot-long Bay Runway is the most widely-used route in and

out of JFK. When work to resurface the runway began in July 2009, one CSDA member was “flight-ready” to start the project’s concrete and asphalt cutting work several months later.

The new concrete surface is expected to last around 40 years.

The Bay Runway is the longest runway at JFK Airport and is one of only three in the U.S. long enough to land a NASA space shuttle. The runway was last resurfaced in 1993, when it was overlaid with asphalt. The existing surface was now approaching the end of its lifespan, so the Port Authority of New York and New Jersey developed a $348.1 million project to resurface the runway in order to increase the utility and efficiency of the runway and decrease the maintenance costs. In addition, high-speed aircraft exit and entrance taxiways were part of the Port Authority’s delay-reduction program so that planes could take off and land on the runway faster than ever before, decreasing the amount of aircraft queuing. These improvements were estimated to reduce flight delays by 10,500 hours a year. A concrete surface was deemed to be a suitable replacement for the existing asphalt surface, as a concrete runway would last 10 to 15 years longer than one covered with asphalt. This choice of surface would also provide the

Diamond Award Ceremony The International Association of Concrete Drillers and Sawers (IACDS) announced the winners of the Diamond Award, an international competition for excellence and innovation in the field of concrete cutting. The winners were presented with their awards at a press conference at the Convention Center on the opening day of WOC 2011 in front of representatives from several IACDS member associations and members of the industry press. Following opening comments from current IACDS President Peter White of the British Drilling and Sawing Association, the awards were introduced and presented by CSDA Executive Director and IACDS Past President Patrick O’Brien.

operators who have progressed through the company’s apprenticeship scheme,” she added. Taking 2nd place was Thayr sl of Spain, for its work on a wharf expansion project at the Port of Huelva in the Southeast region of the country. The cutting work was performed underwater using diamond wire sawing techniques to cut and remove 26 reinforced concrete pilings that were 4 feet in diameter. “It was difficult to determine the underwater cutting depth—a real challenge—so we are very satisfied with winning our first Diamond Award,” said Victorria Garcia de la torre Acosta of Thayr sl, who was present with Fabian Alcudia Aranda to receive the 2nd place award. The 1st place award was presented to another CSDA member and 2nd place winner from the 2009 competition, Tondin srl, of Italy. The company performed outstanding work in the tunnels of a rail system

Concrete Cutting Reaches its Pinnacle


major construction project is taking place in the heart of London’s financial district. Anticipated for completion

in late 2012, The Pinnacle, also known as The

Bishopsgate Tower, will stand as the second-tallest building not only in the United Kingdom but also the entire European Union. In order for the new tower to take shape, however, an existing building had to be demolished on the proposed site. The building had several levels of concrete floor slabs and reinforced piles that required cutting and removal before work on the new construction could begin.

Octagonal openings were created through five concrete floor slabs.

The 288-meter- (945-foot) tall, 63-story tower was designed by architects at Kohn Pedersen Fox of New York. The Pinnacle was originally proposed to stand at 307 meters (1,007 feet) but had to be scaled back due to concerns from the U.K.’s Civil Aviation Authority. The existing building was demolished to ground level by Keltbray Limited of Esher, England, with three basement levels retained and new piles installed through the basement slabs to support the new structure. Keltbray then needed to form 140 octagonal and 150 circular openings, ranging from 1.4 meters (4.6 feet) to 3.1 meters (10.2 feet) in diameter, through four levels of reinforced concrete floor slabs from the ground floor to the basement raft slab. This would allow for the installation of 2.4-meter- (8-foot) diameter piles. The floor slabs were 600 millimeters (23.6 inches) thick while the raft slab varied in thickness from 3 meters (9.8 feet) to 6 meters (19.7 feet). In addition, there were several concrete

Regular readers of Concrete Openings may remember another U.K.-based story from our December 2009 issue about core drilling and sampling at The London Shard site. Located approximately one mile south of The Pinnacle, The Shard will be the tallest building in the country when completed around six months earlier than The Pinnacle. The Shard will stand 310 meters (1,016 feet) tall when finished, however because the building is located on the South Bank of the River Thames it is not technically in the City of London, and therefore not the tallest building in the city. The Pinnacle gets to claim this accolade. Stitch drilling created 150 circular openings in the basement raft slab.

By using diamond tools and organizing an aggressive work schedule, Kilnbridge was able to complete the concrete cutting work on time and within the specified budget. The Drilling and Sawing Association has confirmed that this is the U.K.’s largest ever drilling contract. “Kilnbridge undertook a complex scheme of concrete cutting, drilling and sawing to effectively cut and sever the heavily-reinforced concrete structure to facilitate the most effective and environmentally acceptable demolition process on both the superstructure and substructure phases of the works,” said Andy McClaffertey, project director for Keltbray Limited. “The works were in a city center building that had a lot of logistical challenges, but Kilnbridge persisted and overcame these challenges without fail.”

was attached to an existing concrete wall, so operators had to chip out and expose each end in order to burn through the steel using long-neck torches. The contractor shored each trough before cutting commenced. With the ends of each trough exposed, a 250-ton crane was used to sling each one and remove them. It took two operators 12 hours to cut each of the 36 troughs free with a WS25 wire saw from Diamond Products. The removal of the concrete troughs was completed first in order for the cutting contractor to be able to access the main concrete support structures in each bay, as these structures also had to be removed. The main 40-foot-long, 5-foot-wide, 4-foot-high and 16-inch-thick support structures were

down into six sections weighing between 2,500 and 7,500 pounds each, and this process was repeated in each of the three bays. Each structure was “U� shaped and pick points for the cut sections were cored so that the structures could be removed by crane. Dimas and Meco hand-held core drills, together with rotary hammers from Hilti, were also used for the picking and some breaking of the sections. Wire sawing averaged 13 feet per cut, giving a total of 468 linear feet for the cutting of the troughs and support structures. The contractor determined that there would be distinct time and cost advantages to using the wire saw for this project. It took two days to finish the cutting in each bay with the wire saw, compared with an anticipated six days of cutting per bay using a wall saw. This also minimized the amount of time that the crane was used on the job providing important savings for Austin Enterprise. The biggest challenge facing this CSDA member at the water purification plant was the limited space for cutting. Austin Enterprise had to make sure that all existing concrete structures and supports underneath the work area were not disturbed or damaged. Preserving the structural integrity

2 2 | M A RCH .1 1

of surrounding buildings and structures was made easier by the use of diamond wire, as this application provided the required levels of noise and vibration to complete the work quickly, safely and efficiently. The cutting team estimates that the use of the wire saw increased their production by 80 percent, enabling them to remove large pieces of concrete in a short period of time while eliminating the need to construct false walls to protect the existing structures from debris. In addition to the restricted access at the plant, there was a series of scheduled shutdowns during which the cutting work had to take place. These strict time frames were specified so that the plant could continue to function with as little disruption as possible. These shutdowns ranged from 10 hours for new tie-ins to 24-hour shutdowns for the sawing of weir wall openings, and even a 90-day shutdown for the sawing of the sediment basins. The project involved cutting in areas of limited access and overhead working conditions. In instances where the cutting area was without the use of a fire or smoke alarm system for more than four hours, a person was designated to stand as a fire watch. The work area was properly ventilated and the crane rigging was secured to meet federal standards at all times. In addition to the wire saw and hand-held core drills used on the job, Austin Enterprise employed two Meco 65-horsepower slab saws from Diamond Products and a Longyear wall saw to cut and remove the concrete troughs and main support structures from the three flocculation bays. A GDM hand saw and Partner ring saw were also utilized during the job. In total, the contractor made 500 linear feet of wire saw cuts through 14-inchthick concrete and 300 feet of wall saw cuts to the same thickness. Over 100 core drill holes were made, ranging from 24 to 72 inches in diameter and 14 to 24 inches in depth, and 950 rock drill holes were created for new dowel bars. A flat saw cut through 14-inchthick concrete to remove catwalks, totaling 275 feet of cutting. Altogether, over 24,300 cubic feet of concrete was cut and removed from the plant. The project was completed on time and within budget. Due to the success of this job, Concrete Openings 2_3 Page December 2010.indd 1 w w w. CSD A .ORG

Austin Enterprise received two more jobs from SSC Construction at the site, performing cutting work on concrete columns in the new parts of the plant and demolition work at the existing site maintenance yard. The site supervisor for Austin Enterprise, Darold Buskirk, was extremely satisfied with the project, “We finished early, picked up additional work and went the duration of the project—three years—without incident. So overall the job was a great success,” he said. “At any one time we had 5- to 10-man crews performing diamond cutting, demolition work, or both.” New portions of the Henry C. Garnett Water Purification Plant were open for use in 2009, while the dismantling and demolition work associated with the existing buildings and structures was due for completion at the end of 2010. The plant now has the capability to provide 72 million gallons of treated water each day to the Bakersfield metropolitan area. REVIEW AND COMMENT ON THIS ARTICLE AT:

the business and bring in sales, as the likelihood is that this won’t happen. Without the owner and management team involved, it is hard to meet the business’ sales goals. Leaders Commit to Sell As a business owner, the only way to grow a company is to take personal responsibility to get it done. The owner must also be the leader, and must lead by example. To be successful, a business owner must spend time with their customers and make the sales. Owners should ask themselves what is their personal commitment to selling. Is it this week, this month, this quarter or this year? Leaders generate revenue. A personal sales approach, utilizing face-to-face appointments with the top 20 to 50 prospective customer targets, is what it takes. Every breakfast and lunch is an opportunity to be with one of these prospects. It is possible to arrange at least one or two meetings with potential and current customers from the company’s list every day. Weekly progress reports can be distributed to a company’s management team to show that the business owner is committed to making sales happen. A business owner should lead by example. Only by this example of leadership will the rest of a management team get on board as well. A good way to move a company forward is to make selling everyone’s priority. Get sales commitments from every management team member. If some are not willing to, or simply cannot make it happen, then these people can be replaced with others who can and will sell. Business owners cannot grow a company without 100% commitment from everyone at the top.

Diamond Chain Proper Chain Selection It is important for operators to select the correct chain for the job. There may be more than one type of chain available at the shop, so choosing the right one is crucial. Like other cutting systems and technologies, there are different diamond segment “recipes” for cutting different types of material like brick, block or concrete. Each recipe is formulated to specifically cut that particular type of material. Choosing the right chain with the right segments will not only improve performance, but will save time and money.

decrease the power of the cutting system. Used Chain Re-installation Before re-installing a used chain, operators should inspect the segments and drive links for damage. Just like with other diamond tools, the chain has been used and a direction of cut has been established, so operators should look for the diamond crystal and bond tails on the segment. The chain should be installed so the diamond crystals lead the bond tails during the cutting process. This helps avoid wasting a layer of diamonds when cutting begins again.

Sprockets Proper Care and Maintenance of Nose Sprockets The nose sprocket inside the guidebar is cooled and lubricated with water. The guidebar has water channels inside it that delivers water to the chain drive link groove and also into the roller bearings inside the nose sprocket. Dirty water, or water scum, inside portable storage tanks can clog the internal water ports of guidebars and starve these critical components of cooling and lubrication.

All Eyes on Contractor’s Wire Saw During Pillar Removal


sing diamond wire to cut concrete is one of the most challenging applications for sawing and drilling contractors. This innovative technique originated in quarries to extract stone and is ideal for

cutting thick concrete where access is limited. Careful planning and set-up procedures insure the work is completed quickly and safely. When a CSDA member was chosen to cut and remove 20-foot-tall concrete pillars from a lake in Missouri, wire sawing offered a safe and efficient solution.

3 4 | M A R C H .1 1



The Harry S. Truman Dam and Reservoir, also known as Truman Lake, is located between the cities of Clinton and Warsaw in Missouri. The 56,000-acre lake is the largest manmade lake in the state and is surrounded by more than 100,000 acres of land for outdoor recreation activities such as hunting, hiking and horseback riding. The dam, located at the lake by the Osage River, sits about 1.5 miles northwest of Warsaw, Missouri, and regulates water flow to produce hydroelectric power while providing flood control for the Southwest Power Administration. The U.S. Army Corps of Engineers completed construction of the dam and reservoir in 1979 and still manage the site today. In the early 1960s, a series of concrete pillars was installed close to the water’s edge to run electrical and utility services across part of the lake. Since the pillars were installed, severe weather and corrosion had caused many of the pillars to tilt. This rendered the pillars structurally unsound so the decision was made to have them removed. The task facing the chosen contractor was to cut and remove the 12 cylindrical reinforced concrete pillars that were each 4 feet in diameter. The pillars stood 20 feet tall from the bottom of the lake, and it was specified by the U.S. Army Corps of Engineers that they be cut as close to the bed of the lake as possible.

Too Sick to Work? By Erin O’Brien


he average U.S. employee takes 5.8 sick days per year, a number that probably seems too high to employers but pretty

low to employees. There is a quiet battle between the two parties about the subject of ill time and this raises the question, how sick is “too sick” to work? Colds and the flu are two of the main reasons for employees missing work, although other related illnesses and conditions can account for missed days. For the most part, a mild cold or minor allergy symptoms do not require complete rest, and the employee does not need to stay home. The important thing

not respond to antibiotics, but the condition will improve on its own in three to five days. Bacterial pinkeye will respond to antibiotic eye drops and the employee can return to work 24 to 48 hours after starting treatment. Pinkeye caused by allergies or irritation is not contagious and employees can continue to work. Staph infections are another type of highly-contagious infections. Staph infections usually present as an abscess or something that looks like an infected cut or insect bite. They are easily treated, as long as it is community-acquired (compared to hospitalacquired, which can be much more serious and difficult to treat). Early detection is key,

as the longer the infection goes untreated, the worse it becomes. Treatment comes in the form of antibiotics and avoiding contact with the infected area. Methicillin-resistant Staphylococcus aureus (MRSA) is a more severe form of staph infection that is resistant to typical antibiotic treatment, as well as being highly contagious. In both cases, it is important to see a doctor and make sure the affected area is covered at all times to prevent spreading the infection. Employees whose job includes possible skin-to-skin contact with other employees should use caution to avoid infecting coworkers. Left untreated, staph and MRSA infections can lead to more severe complications. One of the most important things an employee should consider when deciding whether he or she are too sick to work is the welfare of their coworkers and the effect their illness will have on them. If the employee works in close proximity to several others, or is so sick that he or she is unable to function effectively at work, it is advised that he or she take a day or two to rest at home. Employees should follow the golden rule—treat others as they would like to be treated.

A steel pipe casing is inserted into the drilled hole to prevent the possibility of collapse. Typically, there is a 1- to 2-inch void space between the casing.

the drill pipe and the casing. This noncementitious material is formulated to meet the special requirements for each well.

Cement Slurry Jim Jarl, the quality control manager of Class H oil-well cement for Texas Lehigh Cement, Buda, Texas, says the cementing operation for an oil well is very difficult. The challenge involves filling the space between the steel casing and the dirt or rock sides of a well with a mixture of cement and various other materials designed to best secure the formations and bond to the casing. The void is typically 1 to 2 inches, and must be completely filled to secure the casing and prevent water or anything else from corroding the steel casing or escaping from around the outside of the casing pipe. “The cement slurry must adhere to the pipe and completely fill the space with no voids,” Jarl adds.

To fill the void around the casing, a measured amount of cement slurry is placed inside the casing. Next, a rubber plug is placed on top of the slurry and water or seawater is typically pumped on top of the plug to pressure.

below the surface where temperatures can start at freezing and soon exceed 300 degrees Fahrenheit in the ground below. “At 300 degrees Fahrenheit, normal portland cement can set instantly,” says Jarl. “So the mixture must be designed to meet the specific expectations of each well.” Drilling slurries can be very complicated, starting with the cement. Class H Portland Cement is only used by the oil drilling industry and there are few cement producers who make it, as the product is considered high risk. Manufacturers remove the calcium aluminates (C3A) from the cement in order to provide a longer setting time. The fine aggregate used is entirely dependent on well conditions. Companies develop mixes based on the conditions of a well. Mixes that must be heavier use hematite aggregate (an iron compound), mixes that must be lighter use fine-graded silica or silica flour, and clay materials can be added to reduce shrinkage. Retarding and super-plastering admixtures also are common.

How Drillers Install Cement Slurry Time is of the essence when installing cement slurry, because the cost of drilling per hour is very high and drilling operations cease while slurry is placed around casings. The mixes created for an application must give the installer just the right amount of time: The slurry must not set before placement is complete but should ideally set shortly afterward so drilling operations can proceed. Companies that design and install these mixes often make their own propriety admixtures to more carefully manage these exotic mixes. To place cement slurries, contractors carefully calculate how much material is needed to fill a space. Then they pump that amount

OSHA Requires That Employers Ban Texting While Driving In a recent open letter to employers, Assistant Secretary of Labor for the Occupational Safety and Health Administration (OSHA) David Michaels said, “It is your responsibility and legal obligation to have a clear, unequivocal and enforced policy against texting while driving. Companies are in violation of the Occupational Safety and Health Act if, by policy or practice, they require texting while driving, create incentives that encourage or condone it or structure work so that texting is a practical necessity for workers to carry out their jobs. OSHA will investigate worker complaints, and employers who violate the law will be subject to citations and penalties.” OSHA will use its General Duty Clause, Section 5(a)(1) of the Occupational Safety and Health Act, to issue citations and proposed penalties in these circumstances. OSHA considers “distracted driving,” which can include texting (and potentially the use of cell phones for telephone calls), to be a recognized hazard to employee safety under the General Duty Clause. Penalties for willful violations of the Act under the General Duty Clause can be as high as $70,000.

ing states similar bans are in place at the county or city level. Additionally, in 2009 more than 200 state bills were introduced that ban cell phone use—both texting and talking. These laws make texting while driving illegal and also open employers to liability for accidents that result from the distracted driving of their employees.

In Virginia, a major California-based law firm was sued for $30 million by the parents of a 15-year-old girl, who was killed by a car driven by one of the firm’s lawyers while the lawyer was utilizing a cell phone. A jury ordered the attorney to pay the family $2 million and the law firm settled for a confidential amount. Beyond potential OSHA administrative penalties and civil and criminal liability, employers should also consider how their policies and practices can affect their insurance rates. There is no question that with an increase in accidents caused by distracted driving, the cost of worker’s compensation and other insurance coverage will rise.

MIT Announces Groundbreaking Research to Set New Standard for Life-Cycle Assessment The Massachusetts Institute of Technology (MIT) has released preliminary research findings that will help set a new standard in life-cycle assessment (LCA) modeling. The studies, which are part of an ongoing research initiative at the MIT Concrete Sustainability Hub, will quantify the cradle-to-grave environmental costs of paving and building materials and will ultimately result in the most comprehensive LCA model produced to date. The scope and detail of MIT’s LCA model will set its current efforts apart from previous work. According to MIT professor and research team leader John Ochsendorf, the expanded life-cycle window—50 years for paving materials and 75 years for building materials—combined with the level of detailed analysis conducted on the use phase of structures and pavements will distinguish MIT’s latest research. Initial reports have shown the importance of including the use phase, with MIT researchers finding that more than 90 percent of residential building life-cycle carbon emissions and up to 85 percent of highway pavement emissions occur during this period. MIT’s ongoing work on measuring the life-cycle carbon emissions of these materials is scheduled to be completed by August of this year. The environmental findings will then be supplemented by economic analyses this year to provide the most accurate assessment of the economic and environmental impacts for buildings and pavements yet produced. As policymakers and political leaders work to account for the environmental and economic costs of public building and paving projects, this type of comprehensive costing model of key materials may provide a roadmap to those who plan these major initiatives. Established in 2009, MIT’s Concrete Sustainability Hub is a collaborative effort to integrate the best science on concrete and similar building materials into industry practices. The hub includes researchers from multiple schools at MIT, including MIT’s School of Engineering and MIT’s School of Architecture and Planning.

From the beginning, I saw tremendous value in networking with industry

leaders. I sought knowledge, and the members of CSDA were willing to openly share their knowledge with me. After a few years, I felt I had learned all the industry secrets, made connections and traveled more than I felt I deserved. So, why didn’t I just sit back, read my free issues of Concrete Openings and enjoy life listening to Jimmy Buffet? Because I truly began reaping the rewards of w w w. C SD A .O R G

Having been given the opportunity to give back to CSDA and the industry, I felt the real value of the association. Over the years, I have seen progressive programs implemented, key business leaders volunteer their time, industry experts offer their knowledge to better the sawing and drilling industry for all and friendships develop at CSDA events and activities. In fact, some of my closest friendships have been made through the association. So, why am I still a member now? It is more important now then ever to have all the right tools to run a successful business. I believe you can get most of them through CSDA, and the association is open for business!

Taking it to the next level.

Husqvarna’s extensive line of wall saws ensures there is a saw to meet your needs. Wall sawing involves a lot of preparation; Husqvarna makes equipment easy to transport and quick to assemble at the site. Every detail is carefully planned and designed to ensure efficient operation. Husqvarna’s line of high frequency electric wall saws include the new WS 482 HF and the WS 440 HF. The new WS 482 HF wall saw boasts more power, larger blade size capacity (62") and offers the best power-to-weight ratio on the market. The saw is operated by radio remote control which allows total control of the sawing process and freedom to move around the workplace. The WS 440 HF wall saw features a powerful, water-cooled electric motor that supplies constant high power to the spindle over a wide rpm range for faster and more efficient sawing. The motor generates 17 hp to the shaft, despite the fact that the saw only weighs 55 pounds. Husqvarna’s WS 460 hydraulic wall saw is built on a modular system where the weight is evenly distributed, making the saw easy to transport, handle and set-up. The two-speed hydraulic motor provides optimal speed depending on material, blade diameter and type of blade.
