A

project was launched in 2006 to replace an existing drawbridge that linked two beach towns on the Gulf Coast of Florida. Over the course of the project,

a large number of holes needed to be created in the concrete machinery deck of the new bridge to position equipment and cogs for the bridge opening and closing mechanisms. The cutting work would take place over an inlet that leads from a local fishing village and tourist spot out into the Gulf of Mexico, so operator and public safety was a priority along with the containment of waste material and slurry.

Conclusions The overall weight of the guard was reduced by over 50 percent from 32 pounds to 14.9 pounds. This was achieved primarily by the change in guard material from ANSI 1025 steel to 6061-T6 aluminum. This weight reduction, along with adding a permanent handle to the top of the guard, should reduce operator strain. The project team did not experience any losses in structural integrity as a result of this change in material. In fact, the possible deflection of the guard side walls was actually reduced by the addition of reinforcing ribs welded onto either side of the new design.

The final design put forward by the students also met the specified reduction in water usage. From preliminary testing under normal conditions, the team found that a saw was operated with a water flow rate From left to right: Greg Urig, Skip Aston, Jason Crowe, Brian Francis, Ryan Kitzmiller and Jerry Tipping.

direct and distribute flow, the amount of water needed in the new design was only one gallon per minute. This change in water usage did not adversely affect the dust collection or cooling of the blade, and was proved by final prototype testing. In addition, the nozzles chosen were only rated for a half-gallon per minute each, for a total spray of one gallon per minute at any given time. This meant that no additional control device was required on the guard and no additional instruction or training had to be provided to the operator.

CSDA’s lead training instructor, Rick Norland, has had many years experience handling blade guards and was pleased that the subjects of blade guard weight and water distribution were chosen for the project team’s research and design. “These are two very relevant issues in the sawing and drilling industry. The results of the students’ research provide guard manufacturers with new ideas and perspectives,” he said.

was because of a 52-foot-long by 5-foot-wide overhang on a part of the wall that would not allow access by the crane.

The team from G&S took 12 days to cut and remove the 12 sections of concrete.

A Hydrostress wall saw from Tyrolit, with a 36-inch-diameter blade from Diamond Products, was used to make the cuts and wet vacuums were employed to collect and contain any slurry. Cutting of each section took three hours, while removal by crane took 30 minutes for each 4.2-ton piece from inside the stadium.

The use of pallets to remove some of the cut wall sections worked well as an alternative method of removing those concrete sections with an overhang, but there were a couple of other factors that presented challenges for G&S. A water supply for cutting, and the positioning of hydraulics at the work area, required some extra effort. The cutting area

the slabs is being performed by three operators with Husqvarna FS 660 T-3, 3-speed diesel saws and two trucks. Slurry is being collected by diesel-powered vacuum systems, designed and manufactured by Grabber Power Products, and stored in a 700-gallon collection tank for safe removal to the recycling facility.

Once work on the tow path has been completed, the contractor will turn its attention to the 500-foot-long by 200-footwide rack area, and the sawing and sealing of joints, for the new concrete pavement. The joints will be 0.5 inches wide with a 0.25 bevel.

To carry out the recycling of slurry and waste materials produced from its cutting work, Salinas has bought a LRS 606 reclamation unit from CSDA member company Liebherr Concrete Technology Co. for its new Slurry is being collected by wet vacuums and stored in 700-gallon tanks.

has paid dividends. The city of Seattle already requires a slurry collection, containment and disposal plan for handling slurry from saw cutting, and now these regulations are being introduced throughout the Puget Sound area. These tight controls are especially important to the state of Washington, as many of its boundaries consist of large rivers and estuaries that flow to the Pacific Ocean. These waterways serve as routes for salmon and other fish to migrate each year, so a safe pH level must be maintained to preserve this environment.

Salinas Sawing & Sealing, Inc. is using three FS 6600 T-3 flat saws from Husqvarna to cut reinforced concrete at the Everett assembly plant.

In addition, the company has so far removed 32,000 gallons of slurry from the job site and recycled 21,000 gallons of water at its recycling facility using a Liebherr LRS 606 unit. Slurry was collected by vacuums from Grabber Power Products. At the time of writing this story, Salinas has completed 75 percent of the tow path cutting work at the Boeing facility.

The Boeing Tow Path project is a good example of how this CSDA member is becoming environmentally proactive with regards to saw cutting slurry disposal, and the hope for Salinas is that the introduction of its recycling facility will give it an advantage over the competition as tighter regulations on slurry disposal are enforced. “We have a dedicated staff member that mans

our facility to control the recycling process and monitor our pH levels,” said Campbell.

“Our facility has been designed specifically to handle large amounts of slurry from cutting jobs like the Boeing project and recycle it in a safe manner. Our customer has been pleased with our approach from the start, both in cutting and recycling,” Campbell concluded.

Tauna Prince, regional sales manager for Liebherr Concrete Technology, is pleased to see a fellow CSDA member using her company’s product to meet slurry control regulations, reclaim water and increase revenue. “At a time when Federal and state governments are looking closely at contractors and how they deal with waste products, it’s good to see companies like Salinas being proactive and offering extra services to their customers.”

She continued, “Liebherr is proud to be part of a solution for contractors that want to be greener while increasing profit.”

The new tow path and assembly route for the Boeing KC-767 Military Aerial Refueling Strategic Transport Aircraft is expected to be ready by 2012.

So far, 32,000 gallons of slurry produced on the job have been turned into 21,000 gallons of reusable water.

Improvement as a Two-Minute Drill: Lessons for Leaders

By Clinton Longenecker, Ph.D.

“Any change worth making is worth doing right and doing it fast!”

—A leader’s observation Developing Two-Minute Drill Mindset For the past decade, change and improvement efforts in nearly every segment of the economy have been studied. It has been discovered that the most successful change efforts happen fast. While speed is not the cause of success, the factors that create and lead to speed in the change process are almost always factors that organizations can and must control if leaders are serious about improvement, and businesses in the sawing and drilling market are no exception.

One of the most daunting challenges facing leaders today is that of planning and executing effective change “sooner rather than later.” Nowhere is this more true than in the construction and renovation industries. These challenges are playing out in two different scenarios across the U.S. In the first scenario, many businesses are firmly in the grasp of an economic downturn that requires cost-cutting, productivity improvement, restructuring and re-alignment so that organizations can survive.

In the second scenario, businesses find themselves going into an upturn that requires them to replace lost capacity, make supply chain adjustments, deal with new realities and solve a wide variety of unforeseen and unanticipated problems. Both of these scenarios have two major things in common: they require effective leadership and speed.

These are “post-installed concrete anchors” —meaning they are installed into cured concrete. They are used to attach core stands, wall saw rails and wire saw pulleys during the course of performing concrete removal and other applications. Because of the nature of these applications, the contractor relies heavily on the anchor performing properly to ensure a safe and efficient workplace.

Insert the anchor into the concrete to the prescribed embedment depth. As a general rule, an installed drop-in anchor should never stick up from the concrete surface. Setting the anchor deeper can be appropriate, as long as consideration is given to the reduced load-carrying capacity associated with a deeper-thanflush installation.

Wedge expansion type anchors are subject

to the same kinds of installation requirements as above, except there is no plug to set.

Design Capacity The second basic requirement is that the selected anchor has adequate capacity to carry the loads that will be applied to it. While this may sound like an obvious step, it is not always an easy task in the concrete cutting business.

There are numerous factors that affect the design capacity of the anchor. Some of the most common are: •

Anchor edge distance and spacing limitations. Most anchor manufacturers provide minimum limits on how close an anchor can be set to the edge of the concrete, and to another anchor.

Violation of these limits reduces the anchor’s capacity and increases the possibility of breaking the concrete.

•

The strength of the concrete— commonly denoted as compressive strength measured in pounds per square inch (psi)—also plays an important role in anchor performance. In general, higher strength concrete results in higher anchor capacity.

We’ve got you covered.

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 inlcudes the new WS 482 HF and the WS 440 HF. The new WS 482 HF boasts more power, larger blade size capacity (62") and offers the best power-to-weight ratio on the market. It is radio remote control operated which allows total control of the sawing process and the 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.

Contractor Takes a Bite out of the Chocolate Factory

When the world’s leading supplier of cocoa and chocolate products planned to expand production at one of its locations in the United Kingdom, it needed to find a concrete cutting contractor that could find the “sweet spot” to help with the installation of new equipment. The refurbishment would require precise cutting with minimal debris so that plant production could continue uninterrupted. One CSDA member had a “golden ticket” to enter the chocolate factory—diamond tools.

T

he Barry Callebaut Company has been producing chocolate for more than 150 years and has 40 production sites in 26 countries

that brought in 4.9 billion Swiss Francs (U.S. $5 billion) of sales revenue in 2009. The company has a production plant in Chester, a city in the north of England, where the company had decided to install four new silo tanks to store ingredients for making chocolate.

Usually made of stainless steel, silo tanks are used for processing and storing liquids, granular materials and related ingredients.

Each of the four 6-meter-tall (19.7-foot) tanks installed at the Barry Callebaut factory measures 1.6 meters (5.2 feet) in diameter and can hold up to 10,000 liters (2,641 gallons) of melted chocolate.

would require the refurbishment of specific rooms and floors in the plant, so Barry Callebaut began looking for suitable methods to create circular openings in reinforced concrete floor slabs for the installation.

CSDA member D-Drill Master Drillers Ltd. of Coventry, England, suggested a practical and controlled method of demolition to create the openings, while also offering vibration-free techniques and a dustless environment—a vital element for the food production company.

“When I originally viewed the work location with the client, the access up to the work area was by staircase only. The floor level of the working area was elevated some five levels up with only the use of a very small goods hoist,” said Neil Wood, branch manager for D-Drill’s Manchester office. “This was going to be our first challenge,” Wood added.

assessments and method statements were compiled to determine the safest ways of working with hoist systems at such a height.

In addition, thorough testing and certification of the lifting and electrical equipment was carried out. This documentation and testing was essential to address the issues of transporting equipment to and from the work area, moving large cut sections of concrete by hoist and keeping the job site clean and hazard-free.

The combined weight of each of the four reinforced concrete cores removed equaled 7.5 tons, which was the result of 23.3 meters (76.4 feet) of plunge sawing and 7.5 meters (24.6 feet) of ring sawing. Cutting of the openings took eight shifts of nine-hour work days, which included all setting up and taking

In addition, hoisting equipment and an A-frame were employed to lower the cut sections from the work area, while the slurry was removed by two wet vacuums and stored in the 1,000-liter (264-gallon) IBC tank via 80 meters (262.5 feet) of plastic piping and a submersible pump.

The cutting work performed by D-Drill was completed within the agreed time frame, and the client was highly satisfied with the results.

it will be used more effectively when the person administering the first aid care is also trained to do so. First aid kits can be used on the job site to control bleeding, clean and cover wounds, splint a suspected broken bone, reduce swelling or treat burns, bites or stings. Treating these types of injuries early with a first aid kit will often reduce the severity of the injury and decrease the amount of time the injured worker is affected by the injury.

As a minimum, each cutting contractor should have one first aid kit in the shop, one in the office and one at each job site. It is recommended that there also be one kit in each truck, as accidents can happen on trips to or from job sites. The kit should be fully stocked at all times and restocked after it has been used. All operators and employees should know where kits are located and how to use them. Kits should be stored in an area that is easily accessible to operators and employees, but also in an area where the kit will not be easily damaged by equipment, debris, water or other hazards. Kits should be periodically inspected to ensure all contents are in good condition and no items are missing. A designated employee, such as the company’s safety director, should be responsible for inspecting and maintaining the kits on a regular basis. Any issues with a kit should be immediately reported to this person.

Having first aid kits in the shop and on job sites is an easy way to keep operators and employees safe. Most kits are inexpensive and come prestocked with all necessary materials. By having one or more kits in the shop, office or job site, an employer is able to show its employees that operator and employee safety and well-being is top priority. First aid kits should be a vital part of every company’s safety plan. The Concrete Sawing & Drilling Association (CSDA) offers several documents and resources, such as Safety Manuals, Toolbox Safety Tips (TSTs) and online safety articles for reference and use by its members. CSDA has also recently released a TST specific to first aid, TST #190, “First Aid Kits.”

OSHA /CSDA Alliance Latest

T

he Alliance between the Concrete Sawing & Drilling Association (CSDA) and the Occupational Safety and Health Administration (OSHA) is now in its fifth year and continues to educate contractors, prevent on-the-job accidents and injuries and provide vital materials to advance a safe work environment for sawing and drilling professionals. Here is the latest news from the Alliance Program.

OSHA Distracted Driving Initiative In March 2008, the OSHA/CSDA Alliance released a Best Practice on the subject of defensive driving (CSDA-OBP-1003) that can be downloaded from the CSDA Website. OSHA is now working with the U.S. Department of Transportation on a campaign to prevent worker-related distracted driving, with a special emphasis on prohibiting texting while driving. As part of this initiative, OSHA Assistant Secretary David Michaels issued an open letter to employers in October, 2010. The letter states that employers have a legal obligation to create and maintain safe and healthful workplaces, and that includes having a clear and enforced policy against texting while driving. The letter also states: “Companies are in violation of the Occupational Safety and Health Act if, by policy or practice, they require texting while driving, or create incentives that encourage or condone it, or they structure work so that texting is a practical necessity for workers to carry out their job.” When OSHA receives a credible complaint that an employer requires texting while driving or organizes work so that texting is a practical necessity, OSHA will investigate and issues citations and penalties where necessary.

OSHA’s distracted driving initiative will also include an educational campaign

Safety CountS

Ladder / Scaffolding Safety and Fall Protection

A

ccidents involving falls, particularly from ladders and scaffolding, can be some of the most severe in the work-

place. Fortunately, they are also some of the most preventable. Using good judgment, being aware of the work environment and wearing the proper fall protection, when necessary, will help keep operators safe on the job.

The rules and guidelines detailed in this article should be followed when working on ladders, scaffolding or working at heights.

Ladder Safety OSHA Reference (Subpart X) 1926.1051 – .1053 Ladders are not frequently used in the sawing and drilling industry. However, this lack of use may be more of a problem than first thought. The fact that operators don’t climb or work from ladders very often may cause as much of a safety concern as if they worked from them every day, as the opera-

2. The feet of portable ladders shall be placed on a solid base and the area around the top and bottom of the ladder shall be kept clear.

3. Straight or extension ladders shall be used at a pitch of 4 feet (1.22 meters) vertical to 1 foot (0.3 meter) horizontal.

4. The side rails of ladders used for access to higher levels shall extend at least 36 inches (91.4 centimeters) above the landing or work platform.

5. Access ladders in use shall be tied off, blocked off or otherwise secured at the top to prevent displacement.

4 6 | d e ce mb e r .10

with safe access suitable for the work being done, but can be a potential hazard for sawing and drilling operators if not used correctly.

To ensure the highest possible level of scaffold safety, operators should be aware of the following guidelines: 1. Fall protection is required when working on scaffolding over 10 feet (3 meters) off the ground.

2. The assembly and dismantling of scaffolding must be overseen by a supervisor and inspected prior to use.

3. Each section of frame scaffolding must be equipped with two cross braces.

6. Mud sills and base plates must be placed under each leg of the scaffolding.

Mud sills must be at least 12 inches by 12 inches (30.5 centimeters by 30.5 centimeters).

7. Damaged scaffolding may not be used.

8. An access ladder or other safe means of entry is required to gain access to the scaffolding.

9. Contractors may not use each other’s scaffolding.

Fall Protection Identifying fall hazards and providing protection for operators is the best way to reduce or eliminate the risk of falls. The U.S. Department of Labor lists falls as one of the leading causes of traumatic occupational death, accounting for eight percent of all occupational fatalities from trauma. Any

time a worker is at a height of 4 feet or more, the worker is at risk and needs to be protected.

The following rules should be adhered to when assessing the risk of falls in the workplace: 1. A floor is considered protected if it is barricaded or protected by a cover that is capable of supporting twice the maximum intended load.

2. Employees may not work without fall protection in areas where an unprotected floor or wall opening exists with a fall hazard of 6 feet (1.83 meters) or greater.

• Wall openings are defined as a wall or window opening with dimensions of 18 inches (45.7 centimeters) by 30 inches (76.2 centimeters) or greater and a fall hazard of 6 feet (1.83 meters).

• Floor openings are openings of 2 inches (5.08 centimeters) by 2 inches or greater offering a fall hazard of 6 feet (1.83 meters).

• Employees may not work without fall protection near any unprotected area where a fall hazard of 6 feet (1.83 meters) or greater exists.

3. Railings are considered fall protection if they are installed as a top and/or mid rail at approximately 42 inches (106.7 centimeters) and 21 inches (53.3 centimeters) respectively. The railing system must be able to support at least 200 pounds applied at any point in any direction. This does not apply to some scaffolds and boom lifts.

Abiding by these rules on the job site and reviewing these rules with new employees will assist in reducing the number of on-the-job accidents. Violation of these safety rules may result in dismissal of an employee and/or the company being investigated by OSHA. Gross misconduct may result in immediate termination of an employee by the company.

The information in this article has been taken from the CSDA Safety Manual. This 204-page document has been developed to assist concrete cutting contractors in establishing safety and health programs that will benefit both employees and owners. The manual is intended to provide a starting point for developing company-specific safety programs, and is available to all CSDA members via the online store on the CSDA Website.

Most states recognize a common law duty to preserve evidence after an accident— requiring a party to preserve those items that can be reasonably calculated to be relevant to a potential lawsuit or lead to the discovery of other admissible evidence.

Depending on the severity of the accident, a plaintiff’s attorney may send a letter immediately subsequent to the incident demanding inspection of the vehicle and request that the vehicle be preserved in its entirety to avoid spoliation of evidence. This is standard procedure in a major accident. In this case, nothing should be done to alter the condition of the vehicle. It is okay to have an expert examine the vehicle and photograph it, but this person should not remove or alter anything.

Electronic control modules (ECM) raise spoliation issues, as data may be lost after the initial download and alteration may occur with the required removal of an ECM. The potential for loss and future ability to download should be discussed with an expert and attorney before proceeding with this action.

judge may even demand to view the photographs before ruling on whether privilege should apply.

The Federal Motor Carrier Safety Administration (FMCSA) creates uniform standards of record keeping that companies need to be aware of, especially with regard to issues of spoliation. It is safe to assume that plaintiffs’ attorneys are aware of them. The following is not meant to be an exhaustive study, but to highlight documents that are required to be retained.

•

Results of an investigation of the driver’s safety performance history must be documented and placed in the driver’s history investigation file and retained. This includes a list of any violations and a copy of the driver’s road test.

•

The employer and the driver must have a copy of the medical examiner’s certificate showing the driver is physically qualified to drive.

•

There are retention rules pertaining to driver logs. The logs are required to be maintained by the carrier for a period of six months.

Motor carriers must maintain records for each motor vehicle they

control regarding inspection, repairs and maintenance for a period of one year and for six months after the motor vehicle leaves the motor carrier’s control. In-house maintenance records, as well as records of maintenance performed by outside facilities, can be requested. Retain records on trailers as well. Retain any documents evidencing changes to the vehicle’s equipment along with maintenance records, as these too can be requested.

In the event of an accident, results of drug and alcohol tests are required to be maintained in a driver’s file. As an aside, be aware that

states can mean a presumption that the destroyed evidence would have been damaging to the party who destroyed it.

Following is a checklist of documents that are routinely requested in a lawsuit. Some are clearly privileged, meaning an attorney will argue to the judge that these documents should not have to be produced, but should still be kept. It is advised that the following records be retained:

records of the driver, the logs of the driver, bills of lading and so on, then these records must be saved. However, if a request is received for discovery three years after the incident and company policy is to destroy those types of records after six months, is it spoliation? It is advised to consult with legal counsel. In a situation where it is known, or reasonably known, that a document may be relevant to anticipated litigation, it must not be disposed. The alternative is to risk a charge of spoliation, which in some states can involve a separate lawsuit in itself or in other 5 0 | d e cemb e r .10

A powerful team.

The DM 340 is the most powerful electric drill motor in Husqvarna’s range with 3,300 watts of power. The gearbox is water-cooled for reduced wear and the three speeds make it easy to set the optimum drilling speed for drill bits with diameters from 2 to 16 in. The motor features Elgard™ which indicates, via the LEDs, when the machine is overloaded to prevent motor damage and increase product life. It also features Softstart™ and Smartstart™ to facilitate a smooth start.

The DS 450 is a rugged and lightweight stand designed especially for the DM 340 drill motor.

The two-speed carriage allows the user to select the speed for maximizing drilling performance. The quick disconnect feature enables the operator to disengage the motor from the drill stand easily and efficiently. The stand also features a V-groove roller carriage which enables the motor and core bit to travel smoothly on the column and requires minimal adjustments. The DM 340 and DS 450 make a powerful, user-friendly and efficient team.

Husqvarna DM 340 & DS 450 - keeping you ahead of the game.
