he health and well-being of employees, and quite possibly that of a business, largely depends on an employer’s awareness and compliance with various rules and regulations. These rules tend to be on a state or federal level, particularly those promulgated by the Occupational Safety & Health Administration (OSHA). The ignorance of or failure to comply with regulations can have potentially disastrous results, both physically and financially.

CSDA has long been dedicated to advancing the health and safety of member companies and employees. By formulating and offering specific training courses, Best Practices, Standards & Specifications and through its alliance with OSHA, CSDA has made available many opportunities to educate and protect workers while on the jobsite or in the shop.

It has become apparent that OSHA will revisit the silica exposure levels previously enacted in its regulation 29CFR 1926 55a. Because silica exposure is a possible hazard on or near any construction site, it is important that the construction industry, and especially CSDA, be intimately involved in the discussion and development of a reasonable permissible exposure level (PEL). A significantly reduced PEL will seriously impact all concrete sawing, drilling, cutting, polishing and removal enterprises.

The association is committed to being proactive in this new rule-

making. A number of years ago, an immense investment of time and effort was made by CSDA Past President Susan Hollingsworth and the association’s Safety Committee. A “silica task force” investigated and documented operator exposure levels for a variety of the services commonly provided by CSDA contractor members. This data was then provided to the members to enable them to better evaluate potential operator exposure levels on any jobsite. Building on this substantial data base, the Safety Committee asked Kellie Vazquez of CSDA member Holes Incorporated in Houston, Texas to spearhead the delivery of a Best Practice to help contractors understand and control silica. The release of this document is imminent and may lead to more documentation on the subject of silica exposure. The association and its members are working to assure that the voice of this niche industry is heard, and that any final rule impacting silica exposure levels—proposed or enacted—is one that is reasonable and will not put contractors at a disadvantage.

Rules and regulations are a fact of life. Working to shape the content of those rules is essential. CSDA Board and committee members are out there working hard, not just to benefit the association but the whole industry. Their efforts are very much appreciated and shows what can be achieved through trade associations like CSDA.

Skill and Accuracy Help Concrete Polisher Hit the Mark

The customer had experienced problems with the durability of its existing polished concrete floors.

Surface preparation work was specified at a new 500,000-square-foot distribution center.

systems had been used, but none of them achieved the long-term durability and ease of maintenance sought by the customer.

GMI set about investigating various components such as concrete placement, finishing, polishing technique and the use of acid blocker sealers. These investigations led Bowman to Florida, where he examined an existing floor system and evaluated its condition and capabilities. It was important to not only look at the general wear of the surface, which had only been in use for a few months, but also its repellency of etching and staining.

By taking time to examine the existing floor system, Bowman was s the customer was the second-largest retailer in the U.S., able to build an accurate model for a series of tests to create an improved, expectations were high.

Once the floor was prepared and polished, representatives of AmerThe planning of this floor polishing project began in 2011, when Mitch ican Engineering Testing, Inc. (AET) examined the surface to see how the Kittel of Ryan Companies approached GMI looking for a solution to his new floor system fared using tests set by the American Society for Testing customer’s needs.

The construction of a new 500,000-square-foot cold storage food distribution center in Rialto, California called for over 13,000 square feet of concrete surface preparation work. Two CSDA members combined to ensure the work was completed to the satisfaction of the client and hit the proverbial bullseye.

C O N C RETE these tests, it was proven that the floor system met industry standards set for abrasion resistance and the repelling of moisture.

The tests were a success, so the new floor system was ready to be used in the field. Discussions were held to determine the best time to apply the polished concrete finish, as this was a large construction project that would take several months or longer to complete. It was agreed that it would be advantageous to the polishing operation if the work could be done before the walls were set in place, but the risk of potential damage to the surface by construction traffic was understood. The decision was made to apply the new system to one of the customer’s facilities in Ohio first, which was already in the construction phase. GMI prepared a 400-square-foot area, half with a normal sealer and the other half with an acid blocker type sealer. The idea was to expose the area to construction traffic and evaluate the performance of each of the two halves, as implementing this new floor system at the front end of the construction phase would create cost savings for the general contractor and customer.

C A SES

Approximately 90 days after the test area was created, the interior construction was complete and the results were analyzed. Despite being exposed to heavy traffic, the floor returned to almost 100% of its reflectivity after being cleaned using standard polishing and sealing methods, and it had not lost any clarity. The general contractor was satisfied and agreed that it could be implemented at the front end of the construction schedule at the new facility in Rialto.

A project management team for the California facility met with the team from GMI to schedule the polishing work, considering other trades that would be present during the work and the impact the polishing process would have on an accelerated schedule. It was agreed that the floor system would be installed prior to the metal stud framing of the building and drywall was to be left off the walls until the polishing work was completed. It was at this stage that Bowman contacted Robert Fruland of Color Surface, an established contractor with more than eight years polishing experience, to do the work.

A 400-square-foot test area was prepared to test the suitability of a new floor system.

“We do polishing jobs that are all shapes and sizes, but this was a big one for us.

The customer is as big as they get, so we were excited to do the work.”

—Robert Fruland of Color Surface

Operators completed a four-step process to refine, densify, polish and seal the concrete surface.

C O N C RETE “We have worked with Andy for over a year and he has helped us a lot. The work he is doing at GMI is ushering in a new wave of polished concrete,” said Fruland. “We do polishing jobs that are all shapes and sizes, but this was a big one for us. The customer is as big as they get, so we were excited to do the work.”

The two CSDA members worked together to perfect the new floor system, with Color Surface using the polishing process on two separate jobs before starting work at the Rialto facility. Work began on July 7, 2013 with epoxy joint filling and minor surface repairs before the contractor initiated the refinement and polishing process. Excess filler was ground down using an 11-kilowatt planetary grinder to produce a clean and level joint.

Ensuring the refinement process met the specifications of the customer was the most critical part of the process. Color Surface needed to grind the necessary amount of surface material to remove some of the top layer but avoid exposing the fine aggregate below. It was important to remain in the darker layer of the concrete, as this layer was the optimal hardness for the application. In order to get a floor as flat and level as possible, operators lowered adjacent areas to match the lowest measured area in the space. This became the base grade for the job. Operators used the same planetary grinding machine to remove an approximate 0.2 inches of concrete, covering 650 square feet per hour.

To achieve the desired finish for the customer, GMI made modifications to the grinding equipment. New tooling receiver plates were attached that could receive the necessary 10-segment diamond tools for the refinement process. Once all scratches and blemishes were removed by these tools, coupled with the application of a surface refining agent, operators switched to a 5-segment refinement tool to continue the polishing process.

This tool is made from natural materials designed to avoid the transfer of spent resins, which if left on the concrete can produce a contaminated surface finish.

Even at this stage, the work performed by Color Surface was sufficient to produce a polished floor system of good quality. However, the contractor knew that in order to create the best surface possible and meet the needs of the customer, the rest of Bowman’s suggested polishing process would need to be completed. Operators continued with the refinement process, using the same refining agent but with a another 5-segment tool that would provide the necessary frequency in the concrete for a highly reflective and robust floor.

Once the concrete polisher and Bowman were satisfied with the level of refinement, operators applied hydro densifier and hardener to the surface. This product sets on the concrete, providing a tough, dust-proof layer. The floor was then capable of repelling moisture and topical spills, making it a far more durable surface.

In total, the team of five from Color Surface worked 10-hour shifts to complete 13,000 square feet of surface preparation and polishing in four days, completing the work on July 11, 2013. The project was completed as planned and the overall costs for the work came in under budget by approx 15%, which pleased the general contractor. For the polishing contractor and GMI, however, the most satisfying aspect of the job was that they were able to maintain a consistent quality of refinement and gloss on the floor. GMI conducted gloss meter tests in several areas of the floor to compare gloss values. The results indicated that the average variance between the areas was within four points and the overall gloss rating was 76, well above the 45 gloss average for this type of surface. and Iwere wererigged very pleased with not the gloss, but the clarity The “Robert cut sections and lifted out byonly a 500-ton crane. on this concrete surface.

From the start, the project was a favorable one for both GMI and Color Surface. The general contractor had a customer that was asking for a better product and had a clear idea of what was to be achieved. This presented GMI with an opportunity to eliminate parts of the process that would not produce the desired results, as this can be a lengthy process if the customer’s expectations are not made clear. Having worked with the general contractor previously and built a good level of trust, GMI was able to relay accurately to Color Surface the needs of the customer. The result was a quality end product that met the expectations of all parties.

“The preconstruction through installation services provided by GMI and Color Surface, together with their quality control practices, are unmatched by any group I have previously worked with. They not only

provided a product to the customer, but an educational experience. The process used on this project will now serve as a best practice for future jobs,” said Luke Martin, project manager for Ryan Companies.

Polishing Contractor Makes the Jersey Shore Shine

Polishing operators restored a concrete floor damaged by Hurricane Sandy.

The surf shop had 5,600 square feet of concrete flooring that needed treating with refining chemicals and equipment.

This May, a CSDA member was given the opportunity to help return a Jersey Shore surf shop to its former glory after a natural disaster caused extensive damage. The task was to rehabilitate 5,600 square feet of concrete flooring to produce a smooth, polished surface in time for the store’s grand reopening.

www. c on c re te ope n in gs.com

urricane Sandy caused a trail of destruction from Jamaica to Maine and left much of the New Jersey shoreline destroyed when it made landfall in late October 2012.

It was the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season and the second-costliest hurricane in U.S. history, costing over $65 billion dollars to date. As Sandy moved up the U.S. Eastern Seaboard, winds reached speeds of 115 miles per hour and the effects could be felt as far away as Wisconsin.

Farias Surf and Sport was one of the thousands of New Jersey businesses affected by Sandy. Established in 1969, the company sells surf boards, beach wear, kayaks and skateboards. Farias has stores in Beach Haven and Surf City, but it was the company’s flagship location in Ship Bottom that was hardest hit during the hurricane. The store was opened in 1983 and underwent a rebuild in 2007. This new building avoided total destruction by Hurricane Sandy but required some renovations before it could reopen.

The business owner wanted a floor surface that was highly durable and easy to maintain.

The Ship Bottom store is situated very close to the shore line, so there is heavy foot traffic from beachgoers who bring in sand and salt water on their footwear—two elements that can cause damage to most floors over time. It was decided that the best option was to polish the 5,600-square-foot concrete floor to produce a hard-wearing, yet aesthetically appealing surface for customers and staff. The floor was damaged as Hurricane Sandy blew through the Jersey Shore, so this was an ideal opportunity to refurbish a surface that, if maintained properly, would last for many years.

Farias Surf and Sport approached New Jersey-based CSDA member Atlantic Concrete Cutting, Inc. to do the work. The CSDA Certified Company set up a polishing division in 2006 to expand its range of services, and was more than capable of meeting the expectations of the customer.

“One of the most important parts of planning a concrete polishing job, is managing the expectations of the customer,” said Jeff Boggs, Atlantic Concrete Cutting’s project manager for the job. “We did two separate test areas at Farias before a quote was even submitted, as we wanted the store owner to be aware of potential issues like imperfections and color variations. It was crucial that he understood not only our capabilities, but also the limitations of the surface itself.”

First, the concrete polishing team from Atlantic Concrete Cutting had to prepare the work area. All walls of the store were covered and sealed with rosin paper to protect them from slurry. Next, a CRMX surface refining agent supplied by GMI Engineered Products was applied to the concrete floor. This agent was applied to aid in the removal of scratches and helped achieve a high level of clarity in the finished floor. This particular agent also contained an encapsulator that separated water from the by-product produced during the refinement process. This meant that all waste material could be classified as solid waste.

With the surface refined, an operator began the grinding the floor with a 10-segment metal bond diamond tool. This type of surface preparation tool produces a more aggressive grind to remove coatings, eliminate scratches and expose aggregate. It is generally used in the first stage of the grinding and polishing process. The operator covered the whole floor area and prepared for the next phase of the refinement process.

C A SES

The process included the use of 5-segment refinement tools to produce a scratch-free surface.

It was then time to switch to a 5-segment refinement tool. This tool is made from natural materials and is designed to not transfer spent resins in the concrete surface, as they can cause contaminated finishes. The refinement tool was used to produce a scratch-free surface. At this stage, the floor could have been sealed but would not have produced the quality finish sought by the contractor and customer.

Therefore, an additional step was included. The application of an additional 5-segment refinement tool provided a frequency in the concrete that was both tight and reflective.

Once the floor was prepared, it was cleaned with an auto-scrubber to remove impurities and covered with a CRMX hydro densifier.

This chemical hardener was applied in liquid form to dustproof the concrete with nano-sized particles. It was applied to keep moisture and common spills suspended on the surface of the concrete much longer than untreated surfaces.

It also improved the abrasion resistance and durability of the floor.

Burnishing equipment was used with sealing agents to provide a spill-proof floor that can repel moisture. w ww. c o n c re te ope n in gs.com

The floor was completed in under a week and the store reopened in May 2013.

The covering was then left overnight to dry before the polishing team returned to burnish the floor the next day. A propane-powered burnisher with a 27-inch-diameter tool was used to polish the surface, giving the concrete a shiny finish that was then covered with a sealing agent. The sealant was added to produce an ultra-hard, watertight and dust repellent surface that was chemical resistant. This was important because the floor would be exposed to high consumer traffic, spills and abrasions once completed. The operator finished the job by doing one last high-speed burnish of the floor.

The polishing team used an 11-kilowatt floor grinder and a walkbehind auto scrubber, which were powered by a 60-kilowatt, 480-volt generator. All diamond tooling and chemicals were supplied by GMI Engineered Products, while burnishing pads were supplied by Norton Pro Diamond. The contractor was able to complete the 5,600-square-foot job over a period of six days with less than 90 man hours, finishing on time and within budget.

“We are very satisfied with our polished concrete floor. It really works well with the open layout of our store and looks super clean. We have very high traffic in our store and it requires low maintenance. Being at the beach, we wanted the floor to be beautiful and versatile. We think this floor accomplishes both,” said Brian Farias, owner of Farias Surf and Sport.

As parts of the Jersey Shore continue to be rebuilt, Farias’ Ship Bottom store reopened toward the end of May and business is returning to this local company. Atlantic Concrete Cutting has helped to put some of the shine back in the shore and is riding the wave of its success. Surf’s up!

The Business of Business

Putting the “Super” Back in Supervisor: OSHA’s Attempt to Make Hourly Employees Supervisors

By Mark A. Lies II & Kerry M. Mohan

I

n order to establish a violation, OSHA must prove a critical element—employer knowledge—which is typically shown with evidence that a supervisor or foreman “knew or should have known” of the violation.

Because employers know (as well as OSHA) that supervisors cannot possibly be present at every location all the time to observe employee conduct, OSHA has attempted to expand employer knowledge by claiming that hourly employees are “supervisors” under the Occupational Safety and Health Act (OSH Act). This is simply because one hourly employee may temporarily direct one of his or her less senior co-workers, even if this hourly employee lacks any authority to hire, fire or discipline the other employees. Based on this interpretation, OSHA has increasingly begun to claim that an hourly employee is a temporary “super-

2 0 | s e pte mb e r.13

visor” in every instance where two employees are working together, because one is able to tell the other what to do.

This article addresses OSHA’s increasing attempt to claim hourly employees as supervisors to issue more citations, and how it may conflict with a recent Supreme Court decision limiting who “supervisors” may be under Title VII of the Civil Rights Act of 1964 (“Title VII”) involving the Equal Employment Opportunity Commission, another entity within the U.S. Department of Labor.

Employer Knowledge The OSH Act and regulations promulgated by OSHA do not impose strict liability.

Employers are not liable under the Act or a particular OSHA standard simply because a

violative condition exists or an accident has occurred. An OSHA citation can only be upheld if OSHA proves the employer either knew, or with the exercise of reasonable diligence could have known, of the presence of the violative condition. Because many employers are corporations, it may be difficult to determine what a corporation “knows.” Case law involving OSHA citations, therefore, has established a general rule that the actual or constructive knowledge of an employer’s foreman or supervisor can be imputed to the employer. In other words, if OSHA can prove that a supervisor or foreman knew, or with the exercise of reasonable diligence could have known, that a violative condition exists, OSHA can satisfy the employer knowledge element of its burden of proof in a contested case.

Who is a Supervisor or Foreman?

According to OSHA Review Commission precedent, “[a]n employee who has been delegated authority over other employees, even if only temporarily, is considered to be a supervisor for purposes of imputing knowledge to an employer.” M.C. Dean, Inc., 23 O.S.H. Cas. (BNA) 1800, 1803 (O.S.H.R.C. 2011); Diamond Installations Inc., 21 O.S.H. Cas. (BNA) 1688, 1690 (O.S.H.R.C. 2006). Thus, it is not the employee’s title or compensation structure that controls whether (s)he is a supervisor, but whether, in substance, the employee is empowered to direct other employees on behalf of the employer.

Under this broad rule, even hourly employees assigned to be a “lead” for a day could be considered part of management for purposes of imputing knowledge to the employer.

Such was the case for M.C. Dean (“Dean”). On August 17, 2009, a journeyman electrician from Dean fell through a skylight on a warehouse roof and suffered fatal injuries. Following this accident, OSHA cited Dean, alleging that Dean also failed to properly guard the skylight.

Dean argued that because all of its three journeyman electricians working at the site were hourly employees, the company could have had no knowledge of any potentially hazardous condition that they encountered on the roof, and the OSHA citation should be vacated. The Administrative Law Judge rejected the company’s argument, finding that one of the hourly journeyman electricians was, in fact, a “supervisor.” The Judge found that the journeyman electrician in question had been assigned as the “lead” for the day of the accident, and had been delegated the ability to control the method and manner in which he performed the assigned tasks, as well as the ability to assign tasks to the other journeymen. Ultimately, the Judge found that Dean had delegated supervisory authority to the journeyman electrician for the day of the accident, and that his knowledge of the potentially hazardous condition was properly imputed to the employer.

Dean appealed the decisions of the Administrative Law Judge and Review Commission to the Federal Circuit Court of Appeals for the Eleventh Circuit. The Eleventh Circuit upheld the Review Commission’s decision, finding that the “lead” had sufficient supervisory authority to qualify as a supervisor. M.C. Dean, Inc. v.

Secretary of Labor, 505 Fed. Appx. 929, 934-35 (11th Cir. 2013). The Eleventh Circuit also found that even though the “lead” employee lacked the ability to hire, fire or discipline other employees, that was not dispositive as to his supervisory status.

T H E bu s i n e s s o f bu s i n e s s The Supreme Court Limits “Supervisors” Under TiTle VII To Individuals Who Can Hire, Fire And Discipline OSHA’s increasing attempts to claim hourly employees as supervisors may run in conflict with a recent Supreme Court decision in Vance v. Ball State Univ., 2013 U.S. LEXIS 4703 (U.S. June 24, 2013). In Vance, decided on June 24, 2013, the Supreme Court addressed the issue of who can be considered a “supervisor” under Title VII, which prohibits employers from discriminating and harassing employees based on race, sex and several other characteristics. Under Title VII, an employer can be held strictly liable for a supervisor’s harassment of a subordinate. Thus, an employer’s ability to defend itself from a harassment claim can rest on whether the alleged harasser is or is not a supervisor.

In Vance, the Supreme Court found that the term “supervisor” encompasses only management-level employees who have the ability to effect “’a significant change in employment status, such as hiring, firing, failing to promote, reassignment with significantly different responsibilities or a decision causing a significant change of benefits.’”. In so holding, the Court expressly rejected the EEOC’s definition of “supervisor” and held that “supervisor” status is equated with the ability to exercise “significant direction over another’s daily work.”

How Vance May Affect OSHA’s Interpretation of Supervisor Although the Vance decision addressed a different statute than the OSH Act, the Supreme Court’s logic seemingly applies to OSHA. Similar to the EEOC in Vance, OSHA attempts to make hourly employees supervisors on the mere fact they may direct or assign less senior employees, even if such employee has no authority to hire, fire or discipline the other employees. The Supreme Court, however, affirmatively rejected the EEOC’s approach, which raises the question whether the Supreme Court would strike down OSHA’s definition of “supervisor.” Until more employers continue to challenge OSHA’s approach to Federal circuit courts (and potentially the Supreme Court), the question of who is a “supervisor” for OSHA remains unclear.

Implications of OSHA’s Attempt to Make Hourly Employees “Supervisors” The troubling thing about OSHA’s claim that hourly employees can be considered “supervisors,” is that it may act differently during an inspection. Under existing case authority, the employer has a right to be present for interviews of management representatives,

2 2 | s e pte mb e r.13

but not for hourly employee interviews. Thus, during the inspection, OSHA may claim that an employee is hourly to prevent the employer from being present during the interview, but then later claim that the employee was a supervisor based on what (s)he said during that exact same interview.

This conduct by OSHA during its inspection is an example of the difficult quandary into which OSHA can place an employer on deciding how to respond: On the one hand, if the “lead” employee is an hourly employee, he would have the right to be voluntarily interviewed by the OSHA inspector in private (although any employee has the right to have another individual of their selection present for the interview), but his knowledge of an alleged hazard could not be imputed to the employer.

On the other hand, if the “lead” employee is a management employee, his knowledge could be imputed to the employer, but his interview would have to be held in the presence of counsel or another management representative at the employer’s election.

Thus, employers must be aware that they cannot rely on an inspector’s representation that a particular employee will not be considered as part of management during the interview process, and that the employer may have to assert its rights or they are waived. Accordingly, it is recommended that all employers carefully evaluate the degree to which they delegate authority to a shift “lead,” “field supervisor” or other hourly employees and consider the following: • In assigning a shift “lead” who is an hourly employee, ensure that the individual is fully trained to inspect the worksite, identify potentially hazardous conditions and report any such conditions immediately to management. On construction sites, this individual would be the “competent person.”

• Consider alternatives to assigning a shift “lead,” such as assigning a management point person to direct the method and manner of the work with input from field personnel as the job progresses.

• When assigning a shift “lead” who is an hourly employee, delegate specifically rather than broadly. Instead of giving the “lead” person a general instruction to “get the job done safely,” give specific instructions as to the method and manner in which the job is to be done, i.e., specific practices to be followed or equipment to be used to limit the assertion that the employee has general supervisory authority.

• In the event of an OSHA inspection, ensure that the inspector is immediately directed

to a management point person instead of the informal shift “lead.” If the OSHA inspector remotely infers or somehow states that a shift “lead” is a supervisor, then the employer should insist on having legal counsel and/or another management representative present during any interviews with the “lead.” Ask OSHA to commit to its position in writing and if the inspector will not do so, which is likely, then the employer must memorialize in writing what the inspector represented.

• If OSHA considers an hourly employee to be a member of management, legal counsel and/or another management representative have the right to attend the employee’s interview. If the inspector refuses to permit legal counsel or other members of management to attend the interview, the employer may refuse to allow the interview to proceed until legal counsel is consulted or the Area Director is called to address the issue.

• If the employer decides to allow the interview to proceed, notify the inspector in writing that the interview is being allowed “under protest,” and that the employer will object to the introduction of any evidence obtained during the interview.

If the employer carefully assesses the status and responsibilities of each of its employees prior to an OSHA interview and asserts its rights to be present at the interview, if warranted, the employer can avoid a potential waiver of its rights and the prospect of an unrepresented employee making binding admissions of legal liability during an OSHA interview.

Pontoon Stays Afloat Giant Bridge Sections Refurbished and Re-employed

2 4 | s e pte mb e r.13

The 720-foot-long concrete pontoon needed to be cut in half.

C O N C RETE

C A SES

Early in 2013, a concrete cutter in Vancouver,

Canada was contracted to help give a 720-footlong pontoon bridge a new lease on life. The globe-trotting 14-foot-tall, 50-foot-wide section of reinforced concrete had originally been cut from a bridge in the United States before being bought and transported north to British Columbia. Now, the pontoon was scheduled to travel even further, but to do so needed to be cut into two pieces.

B

ack in May 2009, the Hood Canal Bridge in the Puget Sound region of Washington State was shutdown for a period of 45 days while pontoon sections were cut, removed and replaced. Regular readers of Concrete Openings may remember that the wire sawing of these sections was done

by CSDA member Cutting Edge Services of Batavia, Ohio [December 2009 cover story]. Tim Beckman, owner of Cutting Edge Services, learned where the cut sections were headed and contacted fellow CSDA member, John van Dyk of Canadian Cutting & Coring Ltd., about the potential job opportunity.

“Tim had been contacted by Seagate Pontoons, the company that purchased the cut sections, to find out how to best to split a 720-foot pontoon in half,” explained van Dyk. “We had previously met at CSDA events, so Tim contacted my company to see if we could provide the cutting services for this project. Based on his company’s wire sawing work, he was able to provide layouts and suggest cutting methods to successfully deliver the contract.”

Seagate Pontoons had been selling other pontoon sections from the Hood Canal Bridge for use as breakwaters and marinas in other parts of British Columbia and Alaska. However, this particular section was to be refurbished and re-employed as a wharf at a barge loading facility on Melville Island, a remote island off the northern coast of Australia. The buyers of the pontoon, Teras Cargo Transport, found it was more economical to have Seagate purchase, refurbish and transport it to this remote location than construct a new wharf on site.

Operators made four 15-foot-deep core holes for diamond wire runs.

Prior to shipping the pontoon to its new owners, a series of tasks had to be completed that included the removal of the parapet walls, the placement of a new concrete topping and the installation of bollards and fenders. However, none of these tasks could be completed until the pontoon was cut into two 360-foot-long halves. This was crucial, as the whole pontoon could not be transported by ship due to its size and weight. The pontoon was situated in Vancouver where it was dry docked, and time was limited. The concrete section was only allocated seven days in the dock because the dock owners had fishing

Hood Canal Bridge Project In May 2009, CSDA member Cutting Edge Services Corp. cut and removed floating pontoons from the 7,269-foot-long Hood Canal Bridge, the world’s thirdlargest floating bridge. For those who may have missed it the first time around, the December 2009 Concrete Openings cover story is still available to read online.

Cutting the pontoon into two 360-foot sections would allow it to be transported to its new owners.

vessels scheduled to arrive the following week to get ready for the start of fishing season in Alaska.

Despite the limited dry dock time given to the pontoon owner, the location was to the contractor’s advantage. Wire sawing the pontoon in the water had been considered, but would have presented a more challenging environment for the control and containment of slurry and would have made access to the underside of the pontoon more difficult. Therefore, sawing on dry land was a safer and more convenient option. Alternative methods for the removal of the parapet walls had also been suggested, but jackhammering would have required repairs to spalled areas and the edges would have required formwork for the new concrete topping.

First, the team from Canadian Cutting & Coring Ltd. set about cutting the 720-foot-long pontoon in two. In order to cut through the 50-footwide, 15-foot-tall cross section with a wire saw, operators had to create four 2-inch-diameter core holes 15 feet deep at 10-foot intervals across the top width of the structure. Core drills were supplied by Diamond Products and Shibuya Company, which were used in 12-inch intervals to create one 15-foot-deep hole.

This allowed the pontoon to be cut in half with a series of five pull cuts using a Hilti WS-15 wire saw and 100-foot lengths of diamond wire supplied

by Cyclone Diamond Products and Multiquip.

Each 150-square-foot pull cut took approximately 10 hours to complete, which consisted of setup and actual cutting time. This was preceded by two days of core drilling to create the necessary holes for the diamond wire runs.

Next, the cutting contractor was tasked with cutting and removing the parapet walls from along the top edges of the pontoon sections. The

w ww. c o n c re te ope n in gs.com

concrete walls measured 3 feet tall, 9 inches wide and ran along each 360-foot edge of the two structures.

Operators track mounted a WS 463 hydraulic wall saw on one wall and a WS 482 electric wall saw on the other, both supplied by Husqvarna, fitted with 18-inchdiameter blades from Cyclone Diamond Products and Husqvarna. The walls were cut parallel to the deck, leaving a 5-inch-tall lip that would act as a form edge for the new concrete topping. Operators cut 1,520 feet of concrete in 12 shifts by cutting 30-foot-long sections and removing each one by crane.

Wall saws were used to remove 3-foot-tall, 9-inch-thick concrete parapet walls.

c o n c ret e o p en i n g s | 2 7

A demolition robot fitted with a modified attachment was used to scrape objects off the underside and side faces of the pontoon.

The last task for Canadian Cutting & Coring was to clean marine growth from the underside of the cut pontoon sections.

A sharpened steel plate was fabricated and welded to the tip of a breaker to create a scraping tool. The tool was attached to the arm of a Brokk 90 demolition robot and an operator began to scrape barnacles and other crustaceans from the structures. The underside of the pontoons had been positioned on supports 5 feet off the deck of the dry dock, so the Brokk was ideal for this limited amount of headroom. After the undersides were clear, the operator needed a longer reach to scrape the 15-foot-tall sides of the sections, so a Brokk 180 was used. This work was done at the same time as the cutting work and took five shifts to complete, clearing over 60,000 square feet of surface area.

In total, Canadian Cutting & Coring performed 750 square feet of wire sawing, over 1,500 linear feet of wall sawing and core drilled 60 feet of holes on the pontoon sections in addition to the scraping and cleaning work.

All work was completed as specified and within the required time frame.

Thanks to the efficient and well-planned work of the cutting contractor, Seagate Pontoons was able to deliver two refurbished cut pontoon sections to their new owners in Australia as scheduled.

“Our strength lies in performing sophisticated cutting and removal projects, so I’m pleased that we could deliver on this job,” said van Dyk. “Had it REVIEW AND COMMENT ON THIS ARTICLE AT: WWW.concreteopenings.com/FORUM.CFM

Work Zone Safety: Six Tips for Concrete Sawing and Drilling Professionals

By Bob Kreuzer

W

hile maintaining a safe work environment is a priority for businesses in the concrete cutting industry, those that operate on roadways face a unique set of safety-related risks. From dangerous equipment, like core drills, wire and slab saws, to speeding vehicles and unforgiving weather conditions, those working to build or repair the country’s streets and highways face a number of challenges to their personal safety.

Statistics from the U.S. Department of Transportation (DOT) reinforce the fact that work zones on streets and highways are fraught with safety-related risks. According to the DOT, there were more than 37,000 injuries in roadway work zones and more than 500 fatalities in the most recent year reported. This equates to one work zone injury every 14 minutes, which is around four people every hour or 96 per day.

While communications around safety in work zones are commonplace in the construction industry—with events like The Association of General Contractors’ National Work Zone Safety Awareness Week or CSDA’s monthly Toolbox Safety Tips—the practice of maintaining and operating proper safety standards on work zone projects in other industries is important as well. Even if the work zone is managed by a higher tier contractor, it is essential to discuss your safety plans with them and communicate to employees to help them stay safe.

The six tips that follow can help concrete sawing and drilling contractors establish risk management strategies to improve the safety of workers, motorists and pedestrians in highway work zones when road improvements are under way.

advised to notify them in advance to review the Traffic Control Plan and help set expectations for the project.

Slow Down Traffic

Establish a Traffic Control Plan All concrete cutting businesses should have a written Traffic Control Plan for each road and highway project. The plan should be based on the Manual on Uniform Traffic Control Devises (MUTCD) or state requirements, which ever is more stringent, and can serve as the foundation for safety within the entire work zone operation.

Numerous factors contribute to the complexity of safety protocols within a Traffic Control Plan, including: the volume of pedestrian and vehicle traffic within the specific work zone area; the road or highway makeup and geographic area of the construction project. It is important to note, however, that effective Traffic Control Plans should depict the sequence of construction operation(s), the construction to be performed and the movements of traffic during each phase of construction.

Also, when police officers are mandated by municipalities to be onsite, the contractor is

It may seem obvious, but the best way to improve worker safety is to slow down traffic.

The signage placed in the advanced warning area can help to accomplish this.

Just as billboards alert drivers to restaurants and attractions further down the road, so does signage that calls attention to potential hazards created by upcoming work zones. The MUTCD will contain information related to the advanced warning area and provide tips on how to strategically place signage in ways that help prevent traffic jams close to the work zone.

In some cases, contractors may also have to consult with state and local authorities to ensure they are abiding by standards mandated by a municipality. Such standards pertain to speed, roadway conditions and driver behaviors.

In addition, it is important that contractors use properly equipped vehicles to slow traffic when larger, slow moving pieces of equipment need to access the roadway from the job site.

Create Barriers The type of warning signs and barriers used between traffic and the work zone is vital to the safety of individuals operating within a highway work zone. Barriers typically include cones and barrels, while warning signs may include diamond-shaped orange signs, flashing arrow panels or “lane closed ahead” signs, which are posted in advance of road construction projects, as well as a “flagger ahead” warning sign, which is posted within the work zone.

While warning signs and barriers certainly help motorists keep a safe distance from

workers, they ultimately provide little protection against vehicles that accidently drive into the work area. It is recommended that the supervisors and contractors working on highway projects be vigilant of vehicles passing through to prevent a potentially serious risk to their safety.

Stay Visible Employees are encouraged to wear highly visible apparel within work zones. Depending on the time of day, a contractor’s clothing will vary.

During the day, it is advised that they wear bright colors, such as lime green or yellow. At night, however, individuals should wear retro reflective gear so that vehicle headlights enable motorists to see them well before entering a work zone.

While these precautions can certainly help prevent an accident from occurring, in the event that one does occur, the supervisor of the project should immediately start an investigation. A prompt notification to the firm’s insurance carrier, as well as proper documentation of the work zone setup using video cameras or pictures, is also recommended.

Enforcement Comes from the Top Senior management plays an important role in setting safety protocols and making sure they are maintained throughout the lifecycle of a street or highway project. While working in a 100% work zone safe environment is an industry-wide challenge due to the nature of the work, managers or owners often have the ability to cultivate an environment that values work zone safety.

Senior management teams should ask the following: Are general work zone safety standards and more specific ones for employees operating on highways in place? If so, are employees regularly reminded to work within those safety standards? Additionally, are projects being supervised appropriately and are those supervisors demonstrating the company’s values about safety? Is the company’s Traffic Control Plan being enforced?

A Traffic Control Plan is most effective when it is communicated regularly to employees.

Prior to beginning any project, senior management should make sure employees understand the plan and their roles in executing it flawlessly. Employees should know the sequence of operation(s), the work to be performed and the movements of traffic during each phase of construction, as well as how and to whom to communicate an emergency or problem should one arise.

Demolition Robots: Preventive Maintenance Tips to Avoid Electrical Issues

By Lars Lindgren

emolition robots can be likened to fire engines. When one is needed, it is usually for a highly critical, timesensitive job where nothing else will do—not the ideal time for a breakdown.

Over the years, these machines have been somewhat unfairly tagged with the ‘high maintenance’ label, but some basic, simple preventative maintenance measures can help avoid problems and ensure that when a demolition robot is called into action, it is ready to perform.

These robots typically run off 480-volt, three-phase power, incorporating an electric motor driving a hydraulic pump, which in turn powers a hydraulic circuit like those found on more traditional hydraulic excavators. Service issues surrounding hydraulic hoses and valves, tracks and basic cylinder maintenance are generally well known. However, the focus of this article is on the electrical side of the equation, where most problems tend to arise and where a little forethought and a preventive maintenance routine can work wonders.

Cabling The root cause of the majority of electrical problems is a poor power supply. Perhaps the single most important maintenance item associated with a demolition robot is the physical management of the power cable itself. A few simple precautions can eliminate a lot of headaches on the jobsite. First, route cables on the jobsite in such a manner that they will not be run over by other equipment. An old saying goes,

3 4 | s e pte mb e r.13

“a demo robot’s worst enemy is a Bobcat.” This is because, often, a skid-steer is busy working around a robot clearing out debris, and it is in those circumstances where the power cable is particularly vulnerable to inadvertent damage.

Even without a skid-steer on site, it is important to avoid dragging power cables around with the machine. A couple of hundred feet of cable is very heavy and puts a strain on the plugs. This increases the risk of snagging the cable and pulling it apart. It is far better to arrange the cable in such a way that the strain is mostly relieved, and only a relatively short length is moving with the robot.

In the same regard, an excellent rule of thumb is to repair damaged power cables

immediately. Veteran contractors with demolition robots will closely inspect all cables after every job and routinely carry out repairs. Some of these contractors learned the hard way, overlooking potential electrical issues that resulted in lost time, unnecessary component failure and repair costs. Adopting a regular inspection and repair program will drastically reduce, if not eliminate, downtime caused by electrical issues. Contractors tailor such programs to meet the quarterly inspection requirements of governmental agencies such as the Mine Safety and Health Administration (MSHA), but the most important thing is that operators are on the jobsite with the safest equipment possible.

Diligent contractors will check for nicks,

pinches, loose plugs, distortions—any blemish that might possibly affect the performance of the cable on the next job—and make the necessary repairs. In addition, the repairs are done properly; never twisting ends together or using electrical tape to cover cuts. The cable is only placed back in stock when the contractor is completely satisfied that it is 100% ready for use, clearly labeling it as such. This routine can reduce downtime on a fleet of robots by over 90%.

Electrical Cabinet A veteran demolition robot operator stated, “A lot of people think that just because it’s electric-powered it’s like a toaster, with no maintenance required.” There can be the misconception that because there is no fuel and no dipstick, there is no maintenance to worry about. Wrong! Remember that a demolition robot is a serious piece of demolition equipment, subject to vibration, bumps and heat on the job, and will respond accordingly. As with any piece of electrical equipment, contacts get loose—fact. On a regular basis, contractors are advised to open the electrical cabinet, clean it out with compressed air and tighten every contact methodically. Make this a routine, like when the machine is idle, for example, and it will pay enormous dividends.

Generators Often overlooked by both safety personnel and electricians, ‘off the grid’ power sources like generators should be properly grounded. A grounding rod can be pounded into the ground according to specifications of the generator and the conditions of the ground. An alternative is to have a qualified electrician tie into a suitable existing grounding point in the work area.

This will avoid a multitude of problems with electronics and improve safety for the operators. One factory service technician remembers a machine that was regularly delivering a shock to the operator when he touched it. Holding the ground probe of his multi-meter with one hand, the technician touched the machine with the other probe and measured 74 Volts in the chassis of the machine! It turned out the generator was sitting quietly on a steel frame on a dry gravel bed with no grounding rod in place.

The voltage had nowhere to go, except to the operator.

Voltage will slowly build up until it finds a way to discharge, either by jumping to the ground or to someone touching or standing near the machine. It can also be discharged if the breaker hits rebar or wet concrete—not a good thing for the machine’s electrical system or even the hydraulics. Think of welding on a machine with the ground clamp attached somewhere on the other end of the machine.

Not a good idea either! Difficult-to-diagnose

w ww. c o n c re te ope n in gs.com

electrical problems often turn out to be nothing more than bad grounds.

A properly sized generator or transformer is also critical. Brokk applications expert August Scalici visited a CSDA contractor in the Southwest U.S. with several demolition robots in his fleet to figure out why one of his larger machines was struggling to operate a crusher attachment. After testing the voltage at the machine and running a number of other diagnostics, Scalici turned his attention to the generator, which at 45 Kilowatts was already borderline for the size of the machine. After checking it with an amp probe under load, he found that it was laboring to produce the required power, ultimately starving the demo robot. The moral to this story is to make sure the correct generator is being used for the size of the machine. Furthermore, have the generator checked by a competent service center on an annual basis to make sure it is delivering the power it claims.

Unfortunately, this particular incident is not that uncommon. In fact, problems can arise even when the power supply is checked by an “expert.” Too many times, problems occur despite local techs confirming that they have checked the voltage. The problem? They did not check the voltage—each of the three phases—under load. The fact is that measuring voltage without load is largely meaningless.

Power Supply Selection An incident that perfectly illustrates the point above happened several years ago inside a plant where a demolition robot had already burned up three electric motors in quick succession. When the factory mechanic arrived on the scene, he quickly determined that the overload relay for the unit had been replaced with one from a larger machine in the owner’s fleet. This overload relay had a setting of 45 Amps, much higher than the recommended 23 Amps. This left the motor without overload protection, which normally is not a problem unless something in the power supply causes the motors to burn up in the first place. With suitable protection in place, the motor would have shut off by itself and been saved.

The mechanic noticed that the motor was single-phasing. He asked the three plant electricians on site if they had checked the voltage, to which they all replied that they had.

The mechanic persuaded them to check each phase under load separately, and they eventually found a large voltage drop across one phase. The robot was hooked up to a switch box, which when inspected revealed the true problem: one of the three contacts—one for each phase—was faulty, causing the large

voltage drop. Thus, a simple routine—making sure the overload relay was the correct one, and checking the voltage under load—would have prevented the loss of three perfectly good electric motors. Sadly, it is often the case that plant electricians will assume the problem is with the machine, so it is advised to check for problems at both ends of the setup.

General Tips •

Use high-quality, water and oil-resistant power cables with good wear resistance.

Only use drip-proof, OSHA approved plugs. Keep the power cords out of standing water. In extremely wet environments, plugs should be wrapped.

• Make sure power cables and connectors are of the proper size for the expected overall length of cable and maximum current draw. For very long cables, start with a much heavier gauge wire for the first couple of lengths to avoid a large voltage drop at the machine end.

• When troubleshooting, check whether the circuit breakers and fuses are properly sized. While it is highly unlikely they will be installed incorrectly from the factory, it is always possible. It has been know for well-intentioned service technicians on site to borrow fuses or breakers from other machines and installed them without first checking that they were the right specification.

• On high-rise jobs, where several lengths of cable are strung up the side of a building, make sure to use strain relievers to take the weight off the connectors.

• Always disconnect the power to the machine from the generator before starting or stopping the generator, and make sure the overload relay is properly set to protect the electric motor.

Demolition robots are an increasingly popular addition to a concrete cutter’s arsenal, and with proper care and maintenance—especially on the electrical side of the equation— they can be the kind of reliable profit center that can contribute significantly to the overall growth of a business.

What a Relief Core Drilling Aids in Construction of Relief Roadway

W

hen a U.K. concrete cutting specialist was contracted to help with a new ÂŁ1.6-billion ($2.5-billion) construction project, creating over 800 holes in just over a month, it had to work as efficiently as possible. Core drilling work was needed to aid in the building of a new 2.7-kilometer (1.7-mile) bridge and was essential for the installation of strengthening and support structures.

Transport Scotland, the Scottish government’s transport agency, began construction of the Forth Replacement Crossing bridge in August 2011, with the project scheduled for completion in 2016. The new cablestayed structure will consist of three slender, single column towers and approach viaducts. The road carried by the bridge will be designated as a motorway designed to provide relief for the existing 2.5-kilometer-long (1.6-mile) Forth Road Bridge. The current bridge provides a vital connection between the county of Fife and the city of Edinburgh, but despite significant investment and maintenance over its lifetime, it has shown signs of deterioration. It has been deemed not suitable as the long-term main crossing of the Firth of Forth, so a replacement was necessary.

As part of the replacement bridge construction, concrete openings were required in the loading area of a nearby dock yard for the installation of support piles. The general contractor for the project is a joint venture

3 6 | s e pte mb e r.13

of Hochtief Construction AG, American Bridge International, Dragados SA and Morrison Construction, collectively named the Forth Crossing Bridge Constructors (FCBC). The FCBC joint venture is responsible for the fabrication of large steel bridge sections at Rosyth Dock Yard, which will be transferred to a loading area to be delivered to the construction site. The steel sections weigh hundred of tons, so the floor of the loading area has to be strengthened to prevent it from sinking or cracking.

The FCBC joint venture needed a specialized contractor to create the openings for the support piles, and awarded the job to CSDA member Holemasters Scotland Limited of Airdrie, Scotland. The cored holes were to measure 400 millimeters (approx. 16 inches) in diameter and be drilled to varying depths of 100-millimeter (4-inch) to 1.6-meter (5.2-foot) thick concrete slabs.

Over 800 holes were specified, measuring 400 millimeters (16 inches) in diameter.

Slab thickness varied from 100 millimeters (4 inches) to 1.6 meters (5.2 feet).

The drilling work would allow for the installation of floor strengthening piles.

“We knew that we had the capabilities to complete the job as specified, but there were some unknown elements. The thickness of the concrete slabs changed from one drilling location to the next, so we were never sure if we were going to be coring a piece that was just 100 millimeters deep or over 1.5 meters!� explained David McArthur, project manager for Holemasters.

The location of each hole was identified by the general contractor in readiness for the drilling work. A grid of over 400 holes was required at one specified area of the 1,000-square-meter (10,764-square-foot) loading bay. Once complete, the same drilling quantity was to be repeated at a second location. All 400-millimeter-diameter (16-inch) holes were spaced approximately 1 meter (3.3 feet) apart and marked by site engineers.

Holemasters arrived on the jobsite in May 2013 and set up at the first drilling point. Specially-fabricated trailer rigs were used to move the core drilling equipment around the work area and set drill rigs in place at each location. The two trailer rigs had hydraulic motors driven by diesel engines and the coring rigs could be lowered and anchored while still attached to the trailers. These rigs also had 250-gallon tanks for storing water needed for the work.

An operator would adjust the speed and depth of the hydraulic core drill to efficiently create the 400-millimeter-diameter (16-inch) holes.

Drilling would continue until the bit reached the bottom of the slab, taking

Return to Rosyth Regular readers of Concrete Openings may be quite familiar with both Rosyth Dock Yard and the Forth Road Bridge, because the magazine has covered three job stories from these locations in the past five years. Another U.K.-based CSDA member, Core Cut Ltd, had previously cut a large steel caisson at the dock yard [March

2009] and core drilled hundreds of 2-inch-diameter holes in the existing Forth Road Bridge for structural reinforcement [March 2012]. To read either of these job stories, or to download a PDF version of this issue’s story, visit www.concreteopenings.com and click on Archives.

from 10 minutes to drill through shallow areas measuring 50-millimeters (2-inches) thick, to around three hours to core holes through 1.6-meters (5.2-feet) of concrete. Each core was removed by a forklift with a lifting eye and weighed between 20 and 200 pounds.

The team from Holemasters was able to create the specified number of core holes in 13 days using two trailer rigs and two operators. Just a couple of months later, in July, the contractor returned to Rosyth Dock Yard to create a similar amount of holes to the same specifications, completing the work over a seven-day period. The general contractor was then able to install support piles in each area, as required.

“This was a satisfying project for us,” said McArthur.

“Despite uncertainty over the slab thickness in some areas, the coring work went very well. The use of our trailer rigs provided both increased speed and safety, as setup times were less and operators spent less time at the controls of the equipment. Our team is fully CSCS qualified (Construction Skills Certification Scheme – a U.K. certification program for work zone competency), so I’m always confident that work will be done to the highest possible standard and in a safe and controlled environment,” he concluded.

Construction of the new Forth Replacement Crossing bridge remains on schedule to open in 2016. Thanks to the work done by this core drilling contractor, the installation of steel supports for the new structure can continue as planned and ultimately provide much-needed traffic relief for the existing bridge.

SOCIAL MEDIA FOCUS

Is Facebook Right For Business-to-Business Marketing?

By Stan Smith

F

acebook has won. One billion members with 50% active daily usage is astounding. Everyone, I mean everyone, I know is on Facebook and some are hopelessly addicted. However, I maintained a smug aloofness toward Facebook.

While I enthusiastically endorsed Facebook as a business-to-consumer (B2C) marketing platform, I routinely voted it off the business-to-business (B2B) marketing island.

I felt that business people did not fool around with photos and chat. Looks like I’m wrong.

B2B warriors love Facebook and are likely to be spending their lunch hour, dead time between meetings and commutes engaging with their network of friends. Heck, almost all of my clients are on Facebook and are wondering where the hell I have been.

Drinking the Facebook Kool-Aid I recently started a general forum on my Pushing Social (PS) Mastermind product, which provides training, tools and resources for building brands through social media content.

The forum was password-protected and open to clients and PS Mastermind subscribers.

The forum seemed like a no-brainer. I wanted to connect with more readers and the Mastermind community is where I wanted to have the conversation. Even with my best intentions, the forum died an anonymous death. Why? It seems that if people are going to log in to have conversations, they go to Facebook,

not the PS Mastermind. Yes, that realization hurt, but it was 100% true. So, I pivoted and created a private Pushing Social Mastermind Group on Facebook. I emailed a small group of PS readers and clients inviting them to the group. The response has been overwhelming, spawning a feisty PS tribe on Facebook. The success makes sense, as most people were already on Facebook and now they can participate in the group with one click.

That was all I needed to see. I gathered my social chips and shoved them into the Facebook pot.

book users rarely sign-off. Facebook is almost as important as their telephone. This means that Facebook is ideal if you want to reach customers where it is easy for them to respond and participate.

Use the three questions as a litmus test for evaluating your Facebook readiness:

When Does Facebook Make Sense?

Can we offer information, entertainment or access that customers will value?

It is easy to underestimate the value customers place on interacting with other like-minded professionals. Simply providing an online place to gather and trade insights can support a B2B Facebook strategy. Funny photos and satirical postcards help but are not required.

For most B2B companies, LinkedIn is a no-brainer. But LinkedIn fills a different role for most customers. Using LinkedIn is an event.

Want to research a new prospect? Search on LinkedIn. Want to promote your latest blog post to a professional audience? Update LinkedIn. Need to talk to sales managers in Pittsburgh?

Place an ad on LinkedIn. Facebook is much different. Facebook is the social dial tone for most users. Photos, social events, chats, video, social games is woven into the Facebook experience. Face-

Where are our customers spending time online?

Think about your customer’s entire experience. It is likely that your customers are on Facebook when they are not actively searching for a specific product solution.

Can we sustain our activity?

Can you stay engaged even when you do not get any feedback from your audience?

It might be months before you see audience engagement. In social media, the most persis-

tent wins. Can you stick with Facebook for at least 12 months?

B2B Facebook Strategies Worth Testing I know that Facebook is a tough sell to the white-collar tribe, but consider these potential strategies:

GT TURBO AIR WALL SAW The Power of a Hydraulic Saw with the Clean Ease of an Air Saw

Customer Loyalty The best way to keep a customer is to never miss a chance to entertain, educate or inform them. Your customers are on Facebook.

They are already committed to your product, so go one step further and invite them to a Facebook group focused on their product or service.

Monitoring and participating in this group will help identify your fans and identify problems before they spiral out of control. It also helps for your customers to rub digital elbows with other customers boosting social proof.

Customer Service Social media has made excellent customer service a must-have for every company. We, as customers, wield incredible power and have amazing reach. Some businesses have reacted to this new power by refusing to participate on Facebook. The problem is that the conversation is happening with or without them. Customers are in control.

I recommend using Facebook as the “tip of the spear.” Talk to unhappy customers. Thank repeat customers. Promote and support fans.

I trust companies that handle bad situations with wisdom, urgency and optimism. Facebook is a great way to showcase that you treat your customers (even the bad ones) with respect.

Culture Prospects and clients want to know what makes your business tick. A Facebook page is a natural way to showcase photos, videos, interesting (even quirky) news and events.

This is not a must-do in my opinion. Your business may not have a rip-roaring good time every day. Do not force something that does not feel right. Check in with your team to see if there is interest in starting and maintaining a Facebook presence. Skip it if you get a tepid reception. It is better to focus on other areas then try to keep a poorly supported Facebook page on life-support.

polished perspective

The Key to Sustainability – Part 1

By Andy Bowman

T

he way in which the concrete polishing industry measures the value of polished surfaces is changing. Since the inception of concrete polishing in the U.S. market, specifiers and end users have embraced gloss metering and written it into specifications.

This is to ensure the contractor maintains the desired level of gloss, provides a consistent

4 2 | s e pte mb e r.13

finish and ultimately gives the end user a floor system that will perform well.

Originally, the first steps in the polishing process were wet cuts followed by a series of damp steps of refinement. In large, the process was finished out with polishing resins that ran with water. Many of the floors processed and finished in this fashion have withstood the test of time and continued to bring value, especially

for end users that have helped retain their glossy appearance with regular maintenance. What does this mean? Why are these floors holding their own and continuing to retain value?

Over the years, it seems perceptions have changed regarding what constitutes a quality floor system. Some industry experts go so far as to say that the industry is in a race to the bottom. Most of the major retailers that specify

Case Study I was once asked by a major retailer to examine a number of their facilities and give them a report on why their polished floors were not meeting expectations. Some of the floors had only been in use for 60 to 90 days but showing signs of deterioration. Testing criteria was discussed and an evaluation process determined. The end user’s sole aim was to make

w ww. c o n c re te ope n in gs.com

polished concrete only budget $2.00 per square foot, or less, and will not issue contracts above that amount. This is a trend that that has driven down the quality of polished concrete in the industry. The irony is that the very same customers that are purchasing these types of polished concrete floors are asking why they are not getting a sustainable floor system. The use of polished concrete is expanding and more first-time end users appear every year.

The potential for contractors to get in the game and offer concrete polishing services has never been stronger. There are many good opportunities out there for contractors, but businesses are operating in a severely fragmented market.

It is quite impossible to look at a specification for polished concrete and not have at least three or four specific items that would require adjustment to satisfy the required gloss levels. A lack of attention to detail on the design and specification end has left many challenges for contractors. Some specifications include a section that is dedicated to describing the process in which the customer expects their floors to be polished. These processes often call for specific grits, a specific time to apply a densifier and the application of a sealer or polish guard—all chosen by the customer and not the contractor.

The problem with these types of specifications, is that they never cover the variable components that polishing contractors need to accommodate. Often, adjustments have to be made in order to produce a floor that is in compliance with customer needs. If you consider all that the specification calls for and you analyze the numbers from a tooling and labor perspective—including a fair national average labor rate—it is near impossible to do the job at $2.00 per square foot. To overcome this issue, some contractors are reducing the amount of grinding steps required on projects to remain profitable. Unfortunately, this is giving the polishing industry a bad reputation. There are a number of things that can be done to increase awareness and become better ambassadors for the industry. The following is an example, describing just some of the important elements to address at the front end of any polishing job.

the end product a more sustainable system long term. The original budget for completing the polished concrete work was almost double the actual contract value, and the fear was that the floor system specified was not correct for its intended use. The company was aware of the cost savings associated with maintaining concrete floors, and wanted to better educate themselves about building a valid specification on the front end.

One of the company’s requirements was to evaluate polished concrete floors at other retail locations in a specific geographic area.

Broader data was required that focused less on the labor elements of the work and more on the application. Often, a national retailer will contract one company to provide a specific end product on a national level to get the best price possible, but there are many factors that can change the results of a floor system from one location to the next.

During the first onsite evaluation, it was identified that the most problematic areas of the floor system were in high-traffic areas of the retail space. A testing process began by casting a high-wattage inspection light across the floor. Immediately, irregularities in the surface were visible and a clear scratch pattern was observed in the concrete. This scratch pattern appeared to be produced by a higher grit, possibly 100-150 grit metal bond, and had been produced by a 3- or 4-head planetary grinder. To confirm this, a local contractor with a 3-head planetary grinder and 150-grit metal

bonds was hired to make a pass over part of the affected area. The entire surface was cleaned before the two surfaces were measured sideby-side with a surface profile meter.

The results confirmed suspicions, so we began to look closer to the walls and outside the major traffic patterns in the floor to conduct similar tests. A gloss meter test was carried out to the specifications of the original contract.

The floor was to achieve a 40 gloss rating, but the specification did not indicate whether the required methods would achieve this level. It did, however, specify that a 3-head planetary grinder would be used along with two acceptable alternates. We sampled five spots spaced 3 feet apart and the readings were between 42 and 57 gloss, well within compliance. So what was happening to this floor system? Why was it failing so quickly?

In order identify the flaws in this system, it was necessary to not only look at the obvious components of the maintenance program but also more subtle elements. This included looking at what was being introduced to the floor from exterior sources, such as sand, ice and other types of contamination from foot traffic. Cleaning products and equipment used on the floor were also examined. A 24-inch auto scrubber, cleaning agents provided by a concrete sealer company and three different grits of diamond impregnated floor maintenance pads were found. None of the items found could have damaged the floor this much within three months, so the problem was else-

where. A soft cotton rag saturated with clean potable water was wiped over the test surface to simulate a cleaning action. When the surface was dry, another set of gloss meter tests was performed. This time, the readings were between 25 and 37 gloss. An average of 18 points was subtracted by the introduction of water and a minimal amount of agitation.

The inspection light highlighted that there was some residual material left on the surface, so another soft cotton rag saturated with a solvent based cleaner (acetone) was applied.

The cleaning agent removed what appeared to be a film from the surface of the concrete.

Another pass with the inspection light revealed a very light pattern in the surface, which appeared to be similar to the one found in the high-traffic area of the retail space. Why was this metal bond scratch pattern appearing?

Profile meters were used to accurately quantify the value of the texture being produced on the surface. These meters are extremely effective and allow polishing contractors to determine the effects of abrasive tooling. The higher the number on the instrument display, the deeper or rougher the texture. The lower the number, the smoother the profile.

All data from the first evaluation site was recorded and four further evaluations were completed in other regions of the U.S. The same evaluation process was used at all five locations, although the findings varied. The scratch pattern from the first location was not found at the others, but some of the other concrete surfaces had lost their gloss.

CORE HEALTH

Personalize Your Diet

By Erin O’Brien

I

t is rare these days to surf the Internet without finding an article, advertisement or testimonial in support of a new diet. One of these diets was highlighted in last issue’s Core Health [CrossFit and the Paleo Diet, June 2013]. However, with each new diet come new questions, such as “Why will this diet work for me where others have failed?” The general answer is that a particular diet will not work for everyone. Lifestyle factors, dedication and motivation all play a part in the success of a diet. Many diets are very strict and all-encompassing, making them extremely hard to stick to. This article focuses on the best parts of several different diets and explains how tying these small parts together can produce an effective diet plan.

Eat Fewer Processed Foods Processed foods can contain hundreds of chemicals, some of which have been shown to have a negative effect on our bodies. Some can even raise a person’s risk of developing a disease like cancer, diabetes or heart disease.

Shop the perimeter of the grocery store, where healthy, minimally or non-processed foods are located. Fruits and vegetables of course, as well as dairy, meat and seafood are located around the perimeter of the store. Some experts even suggest adopting a vegan or vegetarian diet, although this may be unrealistic for some. One option is to go “meatless” one or two days per week. This provides a good opportunity to increase the amount of non-processed foods on your dinner plate.

Eat a Variety of Whole Grains It is important to look at labels and lists of ingredients for food you are consuming. Whole grains provide much higher nutrient levels than processed grains, tend to have fewer calories and added sugars and will help keep you full longer. Examples of processed grains include white flour, white rice and any kind of bleached flour. Whole grains can be found in certain breads and also include brown rice, amaranth, buckwheat and quinoa, all of which have low gluten content. Gluten intolerance (Celiac

disease is an example of extreme gluten intolerance) is exacerbated by consumption of gluten and causes damaging inflammation in the body.

Avoid Added Sugars Some recent studies suggest that sugar is as addictive as some narcotic drugs. Too much sugar in the diet leads to an increased risk for developing diabetes, cardiovascular disease and possibly even cancer. Avoid foods with high levels of added sugar and your craving for sweet foods will diminish over time.

Eat More Fruits and Vegetables Everyone should aim for five servings of fruits and vegetables per day, fresh if possible.

Choose fruits and vegetables high in fiber, such as artichokes, broccoli, avocado and pears, and leafy greens like kale, green leaf lettuce, spinach, arugula and watercress for an extra boost of nutrients.

Eat Healthy Fats from Nuts and Oils Not all fat is bad! Healthy fats (mono and polyunsaturated) have anti-inflammatory properties and can help control cholesterol. Enjoyed in moderation, foods like walnuts, almonds, olive oil and coconut oil are good for you. Avoid trans fats and limit saturated fats however, as these are the type that will cause you to gain weight and can have a detrimental effect on your body.

Eat More Lean Protein Borrowing from the Paleo Diet, lean, grassfed meats are an essential part of a healthy diet for non-vegetarians. For anyone looking to avoid eating too much gluten, grass-fed meat ensures that the animal did not consume processed grain as part of its diet. Also, grass-fed, pastureraised meat and eggs can taste better! Good examples of lean protein are chicken, lean pork, most cuts of beef, organ meats of any kind, cage-free eggs and seafood. For vegetarians and vegans, protein can come from beans and other legumes.

Snack Smart Just because the package claims “100Calorie Snack Pack” or “Fat-Free Cookies” does not mean the food inside is good for you.

Often, low-calorie and low-fat foods are highly processed, with chemicals added to retain the taste while taking out the so-called bad calories or fat. Healthful snacks like a handful of almonds, carrots and hummus or a few slices of cheese can help hold off hunger until dinnertime without undoing the healthy lunch you just ate.

Only Eat When You Are Hungry Just because your co-worker is reaching for a snack at 2:30pm, doesn’t mean you have to as well. Eat when you are hungry and don’t if you are not. New studies have shown some effectiveness to intermittent fasting – either eating normally five days a week and restricting caloric intake to a quarter of your normal total calories for the other two, or using the 16/8 rule, which recommends that you fast for 16 hours and eat during the remaining eight hours of the day. If you find yourself always hungry, you could be dehydrated. Drink a glass of water before each meal to control your hunger.

Try New Foods As a child, I was a very picky eater. There are still a few things I won’t touch, but I have also found that I love foods I used to hate— green beans, asparagus, spinach and even brussel sprouts (sautéed in bacon, who doesn’t love that!). Try something new and you may find your palate has changed, giving you more opportunities to eat healthy.

There is not one particular diet that will work for everyone, and likely there is no perfect diet for each person. However, take cues and suggestions from many different types of diets, and you should be able to make a diet that works for you. Even small changes are better than none.

Exercise Every Day Aim to raise your heart rate and sweat for at least 15 minutes per day, and try to get in four to five sessions at the gym, on the pavement or on the court, per week. If time is an issue, try taking the stairs at work, a quick power walk during lunch or push-ups and air squats when you get up in the morning. Include resistance training in your workout as much as possible – more muscle means more calories burned when you exercise.

Industry Bits Norton Introduces New HighSpeed Gas Saws A new lineup of Norton Clipper CP500 high-speed saws are available in two sizes to accommodate 12- or 14-inch-diameter blades.

The saws feature iLube®, a patented automatic lubrication system that mixes oil and fuel electronically to maximize efficiency and eliminates the need for pre-mixing.

An electronic sensor indicates a low oil level and adjusts the engine to idle, preventing engine damage. In addition, all Norton Clipper CP500 series saws are equipped with an electronic carburetor electromagnetic valve that eliminates the standard choke and half throttle start. The operator simply turns the switch on, primes the engine and pushes the decompression button. A multi-stage air filtration system utilizes patented twin-air inlets to create an air pulsation that draws fresh air in while pushing hot air away from the engine, keeping the saw cool and reducing debris in the filter.

For more information, contact Mark Pendergrass at 254-918-6501 or email mark.s.pendergrass@saint-gobain.com.

Industry professional Thomas Taylor Trussell, 85, of Warwick, Maryland, passed away at his home on July 2. Tom was born in Baltimore on June 12, 1928, the firstborn of Edward and Mary Virginia Siefers-Trussell. One of his first full-time jobs was at Martin Marietta during World War II as a cold riveter. He also served in the Army National Guard during wartime. During the late 1940s and 1950s, Tom began repairing scales and working with concrete.

MEMBER TESTIMONIAL I got started in the industry in 1980. I was fresh out of college and was hired by the company as a concrete cutter. I spent ten years getting familiar with the tools, practices and intricacies of concrete cutting, working on hundreds of jobs. Like most operators, I would come home each day covered in dust and debris. The company was founded in 1959 in Denver, Colorado with just two employees and one truck. When my boss decided to sell the business, I offered to buy him out and I’ve been in charge ever since. We have now grown to 43 employees and 20 trucks. One of the contributing factors to this growth is our involvement with CSDA. It pays to have a good network of colleagues and resources. That is why I appreciate the networking events, exposure and resources that CSDA has brought to my attention. We have been a member since 1995 and have benefitted tremendously from belonging to this

director’s dialogue

Silica Again!

Patrick o’brien Executive Director

Y

es, as you read in this issue’s President’s Page, the silica discussion is back! Nearly 10 years ago, I addressed silica in the introductory Director’s Dialog column in Concrete Openings. At the time, OSHA was proposing new regulations on respirable silica. They proposed a reduction of the Permissible Exposure Limit (PEL) level from 1.0 to 0.25.

The source for this proposal was based upon OSHA’s experience in the manufacturing sector but showed their dismal lack of understanding of the construction industry.

The proposed standard would have required construction companies to initiate many new procedures. An industrial hygienist would have been required to provide sampling services on each site. The contractor would also have to designate a “competent person” to identify and evaluate silica exposure hazards and establish a regulated workspace, perimeter and constantly monitor the quality of the air. The contractor would have to make respirators and Tyvek clothing available to workers, as well as anyone entering the jobsite, including trades working in adjacent areas. Medical screening and exam costs for employees would have skyrocketed.

CSDA sprung into action as this change would have severely impacted the ability of cutting contractors to earn their living. A cutting contractor can easily be on 3-5 different jobsites in one day, which is quite different from a manufacturing plant that operates with consistent operations day after day.

At the time, CSDA Vice President Susan Hollingsworth represented cutting contractors on the OSHA Small Business Advocacy Review (SBAR) Panel.

She calculated that the proposed standard, which OSHA said could cost a small business up to $12,000, would cost her company of 21 operators upwards of $3 million!

Susan and the CSDA Safety Committee developed a simple chart that operators could use on the job to determine if respiratory protection was

6 4 | s e pte mb e r.13

needed, and if so, what type of protection was recommended. This chart was based upon an extremely thorough data collection of cutting jobsites from CSDA members and the National Institute of Occupational Health and Safety (NIOSH). CSDA even invited NIOSH to attend CSDA training classes at St. Petersburg College to observe and advise CSDA. Because of the use of water in the cutting operation, NIOSH recognized that there was very little silica exposure problems for cutting contractors.

This chart that was developed has been used by members over the past decade and has simplified procedures and protected workers at the same time. CSDA makes this chart available to anyone in the industry.

In her page, President O’Day discusses the new focus by OSHA to again introduce a new standard. We are not sure what has transpired since the original proposal to this new one, but it would have been advantageous for OSHA to seek input from the construction industry.

That unfortunately does not appear to be the case, as they are ready to release a new silica regulation without this input.

Ten years ago, the U.S. Centers for Disease Control and Prevention (CDC) and NIOSH data showed that silica in 1968 was a contributing cause in just under 1,200 deaths in the U.S. By 1999, the number had dropped to less than 200. The most recent data collected by NIOSH in 2010 shows that deaths from silica have now dropped below 100 per year. It is curious why OSHA now wants to push for new exposure limits when the number of deaths attributable to silica have dropped dramatically and the industry has developed it’s own standards and regulations to protect construction workers. If OSHA will talk to the construction industry, I am sure that CSDA can contribute to the discussion. Together, we can develop a workable plan to protect workers from silica exposure.

Ready, set, DRILL. When operators need a machine to handle heavy-duty core drilling jobs, the Husqvarna DM 340 drill motor is the right tool. It was designed to provide optimal performance when drilling with 2" to 16" bits. The gearbox is water-cooled for reduced wear, and the three speeds make it easy to set the optimum drilling speed. The Elgard™ feature indicates, via an LED, when the machine is overloading. This prevents motor damage and increases product life. It can be used with the AD 10 automatic drilling system to increase production and bit life. The DM 340 drill motor is powerful and smart.
