he fall season is upon us and, for many contractors out there, this is the time of year when workloads begin to be somewhat lighter and time on the jobsite lessens. This can prove to be a challenging time for some business owners. For those that are in more fortuitous positions, the issue is how to make best use of their staff levels while things are slow. This is often a good time for companies to invest in training programs and other industry resources that can benefit both employees and employers in the long run. It is no secret that skilled, trained employees can improve a company’s bottom line. In the concrete cutting, polishing and imaging industries, having operators and technicians with good working knowledge of their equipment and applications can save a business time and money. More importantly, a business owner can confidently send people out on a job knowing the work will be done safely, efficiently and to the satisfaction of the customer. For the employee, there must be a great amount of pride taken from doing the job right, pleasing the customer and knowing their employer has faith in their abilities. Investing time and money in employee training can have a huge impact on an operator’s confidence and loyalty to the business. Training really is a win-win.

Knowing that the fall/winter period presents concrete cutters, polishers and scanners with opportunities to train employees, CSDA arranges the majority of its industry training courses, meetings and networking events during this time each year. All events are open to everyone and I encourage you to register and attend them. Between October and February 2015, CSDA has scheduled nine hands-on and classroom training courses for professional contractors in four different locations across the U.S. The association remains focused on its mission, “…to promote the use of professional cutting, polishing, imaging and selective demolition contractors and their methods. In support of this goal, the CSDA Code of Ethics demands that members pursue the highest standards of safety, quality and integrity.” With over 4,000 training class graduates to date, the association’s training and certification program is proving to the rest of the construction and demolition markets that sawing, drilling and polishing professionals are highly-skilled and well trained individuals. Be sure to visit www.csda.org and take a closer look at what courses are scheduled. Participating in industry training programs during slower work periods may just prove to be an advantage when things pick up.

The advantages of core drilling with diamond tools
have helped architects and engineers realize the completion of successful projects for many years. Often, core drilling techniques are used for the installation of modern elements that enhance or stregnthen an existing building or structure. This past April, however, a cutting contractor was asked to help with a $1.7-million restoration project that would return a canal lock to its original design. The project involved creating almost 50 feet of partial-diameter core drill openings through 150-year-old stone walls.
In order to reach Lake Erie from the Hudson River in New York, the Erie Canal has to surmount the Niagara Escarpment at Lockport. In the early 1800s, a competition was launched by the canal owners to design a series of locks that would help vessels traverse over the escarpment. The competition was won by Nathan Roberts, a mathematics teacher and land speculator. His design consisted of two pairs of locks so that one flight could be used for boats going uphill north on the canal and the other for boats going downhill south, saving a significant amount of time and water consumption. The locks were constructed from 1817 to 1825 and some were later modified in 1864. The south flight of locks has since been demolished and replaced by a pair of New York State Barge Canal locks, while the north flight—also know as the “Flight of Five”—has not been modified since the 1860s. Having fallen into disrepair, the Flight of Five is now the focus of a $1.7million restoration project that has been underway for 10 years. Phase One is due for completion in late summer of 2014. Phase One includes masonry repairs, new lights, the installation of arched bridges and the restoration of historic railings around the locks. The centerpiece of the work, however, is the installation of authentic working wooden gates at two lock locations—Locks #69 and #70. The gates operate manually, just as the originals did when the locks were first constructed. CSDA member MMG Industrial of Buffalo, New York, was contracted by Hohl Industrial to provide precision drilling and sawing services around parts of the concrete and stone construction at Lock #69. Having been in place for around 150 years, it was found that the walls of the lock had begun to lean inward and were approximately 4 inches out of plumb on either side. In order to return the lock to service and install the new wooden doors with a proper seal, it was imperative that the wall sockets or ‘quoin post sockets’ were amended and brought back to plumb. Quoin posts are the vertical posts at the hinged end of a lock gate on which the gate pivots. The posts are housed in curved sockets within the lock walls. “We utilized our field machining and stone cutting experience collaboratively to create a 30-foot-long, track-mounted system on both of the lock walls,” said Matt Gehman, owner of MMG Industrial. “The track-mounted systems stood vertically and allowed for the precise control of a core drilling system to recut the partial-diameter quoin sockets on both walls.”
W WW. C O N C RE TE OPE N IN GS.COM
There were two existing sockets that needed to be adjusted, with the requirement that they both were returned to plumb and provided 120 degrees of movement for the lock doors when completed. Therefore, MMG set up its drilling system to create 14-inch partial-diameter sockets down 30-foot-deep sections of stone lock walls. The cut surface covered a 120-degree radius of the core bit and each drilling run cored through eleven 30-inch-thick stone courses on the way down. Due to the requirements of the job and the age of the structure, MMG knew cutting with diamond tools was the only feasible option. The job required the cutting of non-homogenous reinforced materials that were 150 years old, so core drilling provided the precise, controlled movement and low vibration needed to minimize the possibility of misplacement or loss of structural integrity. MMG conducted a detailed site inspection to determine the optimal cutting method and achievable tolerances, after which CAD drawings were created to present the trackmounted drilling system to the general contractor. Following approval, the cutting contractor got to work. A Hilti DD350 core drill was procured with 36-inch-long, 14-inchdiameter bits. The manufacturer also supplied nine 4-foot sections of track to mount to the contractor’s 24-inch, 30-foot-long I-beams. MMG’s sister company, MLS Machine, modified the track system and I-beams to ensure proper alignment, as only a tolerance of +/- 0.030 inches was allowed down the entire 24-foot depth of the cuts. Access to the total height of the lock walls was difficult due to ongoing work by the general contractor, so a portable crane was utilized to lower a four-wheel drive, 30-foot scissor lift to the bottom of the lock. This allowed the contractor to quickly set up and adjust the position of the core drilling crew without disturbing other workers. The crane was also used to position the track-mounted drilling system, which was attached to the lock wall by concrete anchors. The contractor then used jack screws to precisely adjust the system against the stone wall. A core drilling operator began work on the first quoin socket, drilling approximately 18 inches per hour through the stone courses. The track-mounted system took approximately two eight-hour shifts to drill down 24 feet to the bottom of the lock wall. The system was then detached and repositioned at the second quoin post socket location and the process repeated. After each drill run, measurements were taken to insure the new sockets were plumb and the specified distance from the lock center.

A 14-inch-diameter core bit was used to drill 24 feet down the lock wall. “The only major hurdle on this project was cutting a partial diameter (120-degree segment) through 30-inch-thick stone blocks. The extended core bit needed to be supported at the top and bottom to prevent ‘camming’ of the bit and stalling of the drive system. The non-homogenous material, along with the occasional bit of steel reinforcement, meant keeping the cut on centerline was a challenge,” explained Gehman. In addition, the inward lean of the lock walls meant the contractor had to start with a heavy cut at the top and blend to almost nothing at the bottom to return the socket to plumb. Having successfully created new quoin post sockets at Lock #69, the contractor was awarded more cutting work at the jobsite. A task was added to adjust a door support on the concrete floor of the lock. The support is essentially a 1-foottall concrete step that prevents either door from closing in too far when the lock is in operation. An operator used a 695F4 gas-powered chain saw from ICS to trim approximately 1 inch off the side of the support to compensate for the adjustments made by the core drilling work. Cuts were made at specified angles so that they met at the correct tangent point from the quoin post sockets, taking eight hours to complete. As the project involved cutting with demolition tools on a structure that was old and in need of restorative work, safety was at the forefront of all tasks. All perimeter railings had been removed for refurbishment, so the scissor lift became a very important piece of equipment for providing a safe working platform. Extension ladders and tie-offs were used to complete work, where required. During the contractor’s work at Lock #69 at Lockport, MMG Industrial performed 48 feet of vertical core drilling through the stone lock walls and made 24 feet of chain saw cuts to remove a 1-foot-tall, 1-inch-wide slice of reinforced concrete from the door

MMG Industrial—2014 Concrete Openings Award Winner Regular readers of Concrete Openings may recognize the company’s name from our June 2013 story, A Job of Stature. The contractor was presented with a Concrete Openings Award for the project during our inaugural awards ceremony at World of Concrete 2014. This project involved the cutting and removal of a 30-foot-tall, 129-year-old monument in Lowville, New York for restoration. When the hollow zinc monument was found to be in need of strengthening, it was filled with reinforced concrete. This seemed like a good idea until rain water ran in through cracks in the zinc. The water froze and expanded between the zinc casts and the concrete filling, damaging the monument. This CSDA contractor used a wire saw to split the monument into sections before using other sawing and drilling techniques to remove the steel-reinforced concrete within them. The job called for precise, low vibration cutting to avoid damaging the monument further. Over 20,000 pounds of concrete was cut and removed from the monument before it was handed over to fellow CSDA member McKay Lodge Conservation Laboratory for restoration work.
Read the Story: This project is just one of many innovative and complex jobs being done by CSDA contractors everyday on jobsites around the U.S. and beyond.

support on the lock floor. The project completed ahead of schedule and within the quoted budget. While the original scope of work was only to core the quoin post sockets pockets, the task of cutting the floor door support was also awarded to MMG. Hohl Industrial was very pleased with the outcome, especially with the fact that all work was completed within the tolerances specified. “The Flight of Five project was very satisfying in that it required the combination of two disciplines to achieve the desired result—portable machining and concrete cutting. The general contractor originally approached us because of our experience in field machining techniques. They initially thought that this project would be a ‘machining or grinding’ job as the quoin socket was only a 120-degree segment of a full diameter. They didn’t feel that a core bit would be able to stay on center and within the tolerance needed. However, we convinced them that a combination of efforts (machining setup with core bits) would be the best approach and they deffered to our experience and recommendations,” concluded Gehman.
Wooden doors were installed that matched the original ones from the 1800s.

2014 IACDS General Meeting International Association Begins its 20th Year
The attendees of the 19th Annual General Meeting, Led by (front row, from left to right): Secretary Daniel Trachsel, President Lars SandstrĂśm and Vice-Presidents Julie White and Norikazu Shibuya. Madrid, Spain was the location for the 2014 annual meeting of the International Association of Concrete Drillers and Sawers (IACDS) on June 12. The meeting drew delegates from several countries, including Austria, Belgium, Germany, Japan, Liechtenstein, Russia, Spain, Sweden, Switzerland, the United Kingdom and the United States. These delegates gathered to share knowledge and discuss how the organization can best represent the industry in an ever-changing market.
The meeting was held in conjunction with the European Demolition Association’s 2014 Deconstruction Forum, a three-day event focused on an area of the demolition industry known as deconstruction—hazardous waste decontamination, concrete sawing and drilling, dismantling, decommissioning, selective demolition and recycling. A series of presentations, discussions and networking events was scheduled to bring professionals from all types of deconstruction together to share knowledge and exchange ideas.
What is IACDS? The International Association of Concrete Drillers & Sawers is an international trade association of sawing and drilling associations from the concrete construction and renovation industry. Its mission is to provide an international union and cooperation of trade associations to support and promote professional development of professional sawing and drilling contractors and their methods. Concrete cutting with diamond tools reduces downtime, maintains structural integrity, reduces noise, dust and debris, and offers limited-access cutting. This umbrella organization of sawing and drilling associations formed in 1995 is composed of the associations from Australia, France, Germany, Japan, Russia, Spain, Sweden, Switzerland, the United Kingdom and the United States.

Delegates from all over the world met in Madrid, Spain, in conjunction with the European Demolition Association’s 2014 Deconstruction Forum. IACDS has taken great strides to advance the industry since its inception in 1995 and delegates remain focused on the mission established almost 20 years ago. Last year, with this mission in mind, representatives from several national associations were assigned tasks to produce new industry documents. This latest series of documents complement the Basic Parameters for Concrete Drilling and Sawing Equipment and Tolerances and Limits for Construction Sawing and Drilling documents revised and updated in 2006. The aim is to have a set of resources that concrete construction and demolition professionals the world-over can use to better understand sawing and drilling techniques and best practices. Documents on the following subjects were approved during the June meeting and will be available from the IACDS website in the near future: • • • • • • •
Descriptions of Existing and New Technology Hand-Arm Vibration Syndrome Key Market Indicators Noise Levels and Hearing Safety Robotic Demolition Silica Control Slurry Handling Procedures
Representatives of the national associations present gave summaries of the current construction market in their countries, then detailed how their associations were coping in terms of membership and dues income. During the past few years, the fortunes of concrete sawing and drilling associations around the world have differed greatly because of the global recession. However, this year’s summaries were largely positive. It seems that signs of economic recovery—no matter how small—are being recognized on all continents. The hope is that this trend will continue and more contractors will once again feel confident enough to invest their money in trade associations that can benefit their businesses. IACDS President Lars Sandström of Sweden now begins the second year of his two-year term, while Japan’s Norikazu Shibuya and the U.K.’s Julie White remain as vice presidents until the next IACDS President is elected in 2015. The next IACDS annual meeting will be held April 2015 in Paris, France in conjunction with the Intermat 2015 international exhibition.

The uneven surfaces of the granite piers presented a challenge to the contractor.
In recent years, four of the piers at the Hayle Viaduct in southwest England had been affected by subsidence. These piers lie in the original creek bed at the center of the historic town of Hayle in Cornwall. To stop the viaduct piers from subsiding any further, action had to be taken. CSDA member D-Drill Master Drillers Ltd. of Coventry was selected by the general contractor, Bam Nuttall, to complete the technical task of drilling 128 holes through the structure using diamond core drills. The 1.5-meter-deep (4.9-foot) holes were created in the granite piers for the installation of structural support I-beams. Holes measuring 152 millimeters (6 inches) in diameter were overlapped to form 16 ‘I-shaped’ openings, created to allow

just a 20-millimeter (0.8-inch) void between the beam to the structure. To make the task more challenging, the piers were twisted and in a curve, meaning all 128 holes were to be angled. In addition, the surface of the piers was uneven, so the mounting of core drill rigs was made all the more difficult. Due to the condition of the piers, the contractor could only work on one pier at a time. Working on multiple piers at once would have compromised the viaduct’s structural integrity. The original Hayle Viaduct was designed by engineer Isambard Kingdom Brunel, a key figure in the country’s industrial revolution and one of its most revered engineers of all time. The viaduct opened in 1852 and was originally a wooden structure before later being replaced with granite. It has a total of 36 arches, measures 253 meters long (831 feet) and stands 10 meters high (34 feet). Today, the Cornish Main Line railway runs through Hayle and the viaduct is a vital part of this 80-mile line, connecting major towns and cities across the southwest region of England. D-Drill had worked with the general contractor previously on a bridge cut-off project. The success of that project was an influence on the company being chosen for this job. Alastair Morley, project manager for Bam Nuttall, said, “D-Drill was involved in the early stages of this scheme, assisting with development and feasibility studies. The project managers gave their professional advice to ensure the successful planning of the works. Together, we resolved a solution to core eight smaller holes in a pattern, rather than one large core, which vastly reduced the risk of damage to the viaduct.” Due to the varying angles of each pier, careful calculations had to be made by D-Drill’s team to make sure holes lined up to the positions marked by the general contractor. Any miscalculation would have caused problems for those grouting the 3-meter (9.8-foot) metal beams, so all drilling tasks were consistently monitored and reviewed throughout the project. The main problem involved with drilling deep holes, is retrieving the center of the core to continue drilling with bit extensions. Ed Taylor, project manager for D-Drill, had custom 1-meter-long (3.3-foot) bits manufactured, which allowed operators to complete each hole with

just one bit change. Operators first used a 500-millimeter (1.6-foot) bit then retracted it, removed the core and attached the longer bit to reach the required depth. Setting up on the uneven pier surfaces required experience and logical thinking, along with the use of wedges, plates and soldiers of wood to achieve the correct angle. Failure to set up correctly would have caused the bit to either rub on the side of the hole or dislodge the fixing, forcing a reset of the rig. “This type of sensitive project required equipment with minimal vibration to avoid causing further damage to the piers. The depth of the material also left us with few options regarding methods, so the plan was to use our very best operators with custom-manufactured bits and rig extensions. Due to the tight tolerances required for the work, we decided that core drilling would give us the control and precision needed to get it right,” said Taylor. First, a measurement was taken from the base and center of the opening at a distance of 343 millimeters (13.5 inches) vertically. This was the shortest distance in the slot on the base plate and allowed operators to drill one hole either side of the first. This meant that three holes could be created from one setup, saving time, cost of anchors and made the whole process more accurate. A 16-millimeter-diameter (0.6-inch) hole was drilled to a depth of 51 millimeters (2 inches) to house a Hilti drop-in anchor and a fixing bar was inserted and tightened to the thread of the anchor. The diamond drilling rig stand was fixed to the wall with the fixing bar penetrating the base plate of the drill stand. Final measurements were calculated and doublechecked before some retightening.

An ‘I-shaped’ configuration was made by making eight 152-millimeter-diameter (6-inch) openings. Drilling of the first hole commenced using the 500-millimeter (1.6foot) tube and the DD350’s slow start mechanism was utilized to prevent the bit segments from dislodging in the uneven granite surface. When the bit reached maximum drilling depth, the motor and bit were removed from the rig and the granite center broken out. This allowed the operator to attach the 1-meter (3.3-foot) bit and continue drilling to the specified

On completion of the first hole, the fixing nut was loosened enough to rotate the stand to overlap the hole by approximately a quarter for the next one. Due to the remote location of the site, D-Drill provided its own generators but was able to tap into the site office’s water supply for use while cutting. D-Drill’s operations attracted quite an audience, as local residents watched the historic structure undergo essential strengthening work. To protect onlookers and keep them a safe distance from the work, a fence was erected by the general contractor. Within the work area, the drilling team was provided with all necessary personal protective equipment to complete the work safely. In addition, the opposite side of the cutting face was cordoned off to protect other onsite personnel. The whole task took a total of 20 working days with two separate teams completing an average of 13 holes a day, drilling 19.5 meters (64 feet) of 152-millimeter-diameter (6-inch) holes through solid granite with three Hilti DD350 core drills. Operators worked to 10-millimeter (0.4-inch) tolerances to leave just 20 millimeters (0.8 inches) of void space in all 128 holes. The project was completed on time and within budget. Supervisor and operator Jason Brown was given special recognition for his efforts on this project. “Jason has completed the U.K.’s Drilling and Sawing Association apprenticeship scheme and has been with D-Drill for a number of years. His attention to detail at the Hayle Viaduct was exemplary,” said Taylor. “I sent my two most experienced men to complete the job but couldn’t help getting on the tools myself for some of the work. This job was so interesting and challenging, it felt like it became part of the history of this site!” he added. The success of this project, coupled with the bridge cut-off project completed a year earlier, has led to the drilling contractor working closely with the general contractor on other similar projects. “D-Drill worked to complete 128 core holes, moving between the four piers in sequence. They worked with efficiency, managing the project with skilled operators and performed to our satisfaction. This ensured effective completion of all tasks within the agreed timescales,” concluded Morley. REVIEW AND COMMENT ON THIS ARTICLE AT: WWW.CONCRETEOPENINGS.COM/FORUM.CFM

THE BUSINESS OF BUSINESS
The Threat Posed by Cyber Criminals By Kristen Long
A
s a contractor, you encounter countless hazards on a day-to-day basis. Most of these risks come with the job and it is your responsibility to take the proper precautionary measures to avoid accidents and property loss (like the implementation of safety programs, insurance policies or alarm systems). With all of the tangible perils faced on the jobsite, one issue that might not be on your radar is cyber liability. While contractors might not seem like likely targets of online attacks, the reality is that all businesses, big or small, are vulnerable to cyber threats. A scary, but prime example of an extensive cyber attack happened just last year, when retailer Target had a credit card breach during the holiday season. You most likely heard or read about it in the news, but what wasn’t as publicized—and what might surprise you to learn—is that the breach originated in a mechanical contractor’s system. The Target cyber attack exposed over 40 million credit/ debit cards and the private information of 70 million consumers. It is one of the largest cyber breaches on record, so how could an ordinary mechanical contractor be involved? It has been reported that while this company was most 2 0 | S E PTE MBE R.14
likely not the initial focus, a simple Google search of Target suppliers displayed the mechanical contractor’s information through a portal on Target’s website, listing the retailer’s third-party vendors. After the hackers received the information, they took a shotgun approach and flooded a large number of suppliers with email malware attacks. Approximately two months prior to the actual Target attack, the malware became implanted in the contractor’s computer system and it opened up the floodgates for the chaos that ensued. In a statement from the contractor, it was explained that, “it used its data connection with Target for electronic billing, contract submission and project management.” Yes, Target’s systems (or lack thereof) played a major role in the breach since they shared supplier information on their website and didn’t have sufficient security systems in place. However, the mechanical contractor is a victim in this crime and still responsible for the layer of infiltration. So while you may be right in thinking contractors aren’t the main targets of cyber threats, your company might be a single piece in a larger
puzzle of entryways to the next big breach. A common, but lethal way cyber criminals slip past defenses is by bombarding victims with phishing emails. In simple terms, phishing emails are counterfeit messages used to acquire confidential information such as usernames, passwords, personal information and credit card numbers. Victims will receive emails that appear to be from popular websites or recognizable companies that contain links within the email. Once a user clicks on the link, it directs them to a fake website that is designed to imitate the actual company website. In actual fact, this site is infected with malware and waiting to obtain all of the user’s information. Phishing infections are effective cyber scams because they have the ability to spread at an exponential rate. The programs are designed to act like parasites—they infect one user, feed off of its resources in the form of user information and then spread to everyone the user comes in contact with. If your personal email has ever been compromised you know how frustrating it can be to ensure your identity and information are safe, not to mention the embarrassment
that comes with finding out you unknowingly sent all of your family and friends the same harmful email. Now imagine the same situation, but instead of you clicking on the link from your personal email, one of your employees accidentally clicks on it from their business email. It not only exposes all of your company’s confidential info, but also distributes the link to each of your clients’ and business partners’ email addresses. This is far more embarrassing and these contacts are most likely less forgiving than your friends and family. Cyber attacks can be devastating and cause your company both tangible and intangible financial losses. Unfortunately, the number of attacks is increasing at an astronomical rate. As reported by Kaspersky, an online security company, the number of attacks topped three billion in 2013. It was once perceived that cyber criminals only targeted giant retail chains and megabanks with large computer systems. But it appears that the game is changing, because hackers seem to be altering their approach. Symantec’s Internet Security Threat Report for 2013, shows companies with fewer than 250 employees were the focus of 31% of all cyber attacks in 2012—a jump of 58% from 18% in 2011. The bottom line is that cyber crime is a real exposure that you, as a business owner, need to protect your company against. While you might recognize the tangible risks involved such as financial losses, business interruption damages and investigation costs, it is more difficult to put a dollar value on the intangible risks of repairing your business’ reputation and correcting the long-term impact of a cyber attack. What systems do you have that might be vulnerable to an attack? Below is the Kaspersky report for IT systems application vulnerability:

As technology has progressed over the past twenty years, so have businesses. Whether it’s a “mom and pop” shop or a Fortune 500 Company, business owners have learned to adopt forms of technology to benefit their needs and stay ahead of the curve. File cabinets and folders have become extinct as information is now stored on paperless systems. Cash transactions are becoming a rare occurrence as businesses have shifted to credit/debit card payments to meet their customers’ demands. Additionally, conducting business in person
1/14/13 10:04 AM
or from a landline phone is increasingly being replaced by emails, texts and Skype calls from tablets and smart phones. There is no doubt that these technological advancements have opened up a whole new way of doing business, but at the same time they have opened the door to a whole new breed of criminal. Thievery and counterfeiting are two very basic crimes that have been around for hundreds of years. Traditionally, robberies only affected individuals or small groups
C O N C RET E O P EN I N G S | 2 1
THE BUSINESS OF BUSINESS of people. Even bank robberies would limit the victims to the customers of a particular bank. Now, we live in a different world where millions of people can be affected by cyber crime at the same time. The advent of the World Wide Web and the ability to store gigantic amounts of data on computers and clouds has given thieves the ability to steal information from the other side of the globe while sitting in their homes. Historically, businesses have always been able to limit a theft loss to their property, but now the exposure exists to lose all of their confidential information along with compromising the information of everyone they know. Your company, no matter what the size, has the potential to unwittingly play a part in a financial crime the size of last year’s Target breach. While there are clear benefits to allowing customers to use credit cards for online payments, the ubiquity of these types of transactions has turned the Internet into a hotbed of cyber crime. In an attempt to remain competitive, businesses have inserted fancy new technology into their operations without implementing the necessary security programs or protocols to keep them safe. This is like buying a brand new pickup truck, but leaving the front door open and the keys in the ignition. Just like old-fashioned street thieves, cyber criminals are persistent. They are constantly upgrading their tools to circumnavigate firewalls and other security measures that companies put in place. The truth is that you’ll never be completely hack-proof, so what can you do? It is imperative that your company purchase a cyber liability insurance policy to protect itself from the crippling costs and hardships associated with an attack. Your General Liability policy has specific exclusions for this coverage, so it is necessary to put this very important protection in place. The most vital part of protecting your company is creating an internal process! The Federal Communications Commission (FCC) has established a small business cyber planner and cyber tip sheet that will be a very useful tool and guide to establish these critical protocols.

Train employees in security principles. Establish basic security practices and policies for employees, such as requiring strong passwords and establish appropriate Internet use guidelines that detail penalties for violating company cybersecurity policies. Establish rules of behavior describing how to handle and protect customer information and other vital data. Protect information, computers and networks from cyber attacks. Keep clean machines. Having the latest security software, web browser and operating system is the best defense against viruses, malware and other online threats. Set antivirus software to run a scan after each update. Install other key software updates as soon as they are available. Provide firewall security for your Internet connection. A firewall is a set of related programs that prevent outsiders from accessing data on a private network. Make sure the operating system’s firewall is enabled or install free firewall software available online. If employees work from home, ensure that their home system(s) are protected by a firewall. Create a mobile device action plan. Mobile devices can create significant security and management challenges, especially if they hold confidential information or can access the corporate network. Require users to password protect their devices, encrypt their data and install security apps to prevent criminals from stealing information while the phone is on a public network. Be sure to set reporting procedures for lost or stolen equipment. Make backup copies of important business data and information. Regularly backup data on all computers. Critical data includes word processing documents, electronic spreadsheets, databases, financial files, human resources files and accounts receivable/payable files. Backup data automatically if possible, or at least weekly and store the copies either offsite or in the cloud. Control physical access to your computers and create user accounts for each employee. Prevent access or use of business computers by unauthorized individuals. Laptops can
be particularly easy targets for theft or can be lost, so lock them up when unattended. Make sure a separate user account is created for each employee and require strong passwords. Administrative privileges should only be given to trusted IT staff and key personnel. 7. Secure your Wi-Fi networks. If you have a Wi-Fi network for your workplace, make sure it is secure, encrypted and hidden. To hide your Wi-Fi network, set up your wireless access point or router so it does not broadcast the network name, known as the Service Set Identifier (SSID). Password protect access to the router. 8. Employ best practices on payment cards. Work with banks or processors to ensure the most trusted and validated tools and antifraud services are being used. You may also have additional security obligations pursuant to agreements with your bank or processor. Isolate payment systems from other, less secure programs and don’t use the same computer to process payments and surf the Internet. 9. Limit employee access to data and information, and limit authority to install software. Do not provide any one employee with access to all data systems. Employees should only be given access to the specific data systems that they need for their jobs, and should not be able to install any software without permission. 10. Passwords and authentication. Require employees to use unique passwords and change passwords every three months. Consider implementing multifactor authentication that requires additional information beyond a password to gain entry. Check with your vendors that handle sensitive data, especially financial institutions, to see if they offer multifactor authentication for your account. In this technology-driven world, cyber attacks are a very real threat and have the ability to cripple your company’s reputation and financial security. Think of it this way: as you lock up your tools, blades, trucks and buildings each night, you must also lock up the doorways to the world that your computers, cell phones and electronic devices are opening every minute of the day.

Contractor Creates Safe Passage from Dry Dock

fter discovering a dry dock was not living up to its name and retaining approximately 12,000 cubic meters (423,776 cubic feet) of water, a dockyard owner began looking for precise, costeffective ways to correct the situation. A cutting contractor was chosen to perform sawing, drilling and breaking techniques that helped remove over 350 tons of reinforced concrete and allowed the dock to run dry.

Operators used stitch drilling techniques, creating 150-millimeter-diameter (6-inch) holes in the dock sill.
Babcock International, the owner of Rosyth Dockyard in Scotland, United Kingdom, found there was a drainage issue at the yard’s Dry Dock #3. At the bottom of the dock, a concrete seismic sill measuring 44 meters (144 feet) long, 20 meters (66 feet) wide and 1.8 meters (6 feet) tall at its highest point was stopping all water from draining. Therefore, it was proposed that a drainage channel be created in the sill that would give a clear path for water to flow out of the dock. Cutting and breaking the concrete with diamond tools was considered the only practical method for the work. These techniques provided the speed, efficiency and precision required to form the new drainage channel in a quick and cost-effective way. An alternative method suggested was to use several large excavators to hammer out the concrete and then cut all steel reinforcement, but this was deemed too time-consuming, costly and would have required extensive cleanup. As concrete sawing and drilling techniques were the preferred method for the work, Babcock contracted CSDA member Holemasters Scotland Limited of Airdrie to create the drainage channel. The contractor has completed a number of projects around the 1,300-acre dockyard over several years [including a core drilling job that was published in our September 2013 issue] so the dock owner was confident this project would be a success.
W WW. C O N C RE TE OPE N IN GS.COM
“We know the site well, but we never take any job at Rosyth for granted,” said David McArthur, project manager for Holemasters. “The job was 20 meters (66 feet) below sea level in a relatively confined area. We had to ensure we used fully-trained crane operators and slingers for the safe positioning of equipment and removal of debris. In addition, a detailed lifting plan had to be written to satisfy the dock owner and we had to secure a qualified first aider for the site.” The contractor surveyed the site and formulated a plan to create a channel that would run lengthways through the middle of the 44-meter (144-foot) sill measuring 1.8 meters (6 feet) wide and 1.8 meters (6 feet) deep. The first task was to negotiate a layer of 50-millimeter-diameter (2-inch) steel rebar at 200-millimeter (8-inch) centers. Operators made four 44-meter (144-foot) cuts 300 millimeters (11.8 inches) deep in the sill using a Tyrolit diesel-powered flat saw. These cuts were spaced to form two 200-millimeter-wide (7.9-inch) tracks along each side of the channel, with Brokk 90 and 180 demolition robots used to break out the concrete in between the cuts. This part of the job took around 18 days to complete. With the tracks and the rebar broken out, it was time to begin stitch drilling. A 150-millimeter-diameter (6-inch) core bit was used along

Other sawing equipment and demolition robots were used on parts of the structure. each 200-millimeter-wide (7.9-inch) track to drill a series of holes 1.8 meters (6 feet) deep. This allowed the seismic sill to be split into three sections, with the 1.8-meter-wide (6-foot) middle being removed completely to create the channel. Each hole took an average of one hour to drill and Holemasters had seven operators drilling at the same time using core drill rigs from Hilti and Diamond Products, completing eight holes during an eight-hour shift. While the majority of the sill was cut using flat saws and core drills, there was one section that required a different method. Running centrally across the width of the sill was a concrete up stand, which had to be removed with a wire saw. The contractor used a Hydrostress saw with a 10-meter (33-foot) length of diamond wire to cut out this section, taking two days to complete. Operators were then able to continue drilling and excavators broke out and removed all cut sections, including the ones created by the wire saw. As the last few cut sections were removed, the dry dock was partially filled and the new drainage method successfully passed the test. Without this channel, it took approximately 24 hours to drain the dry dock from full, even with the use of pumps. The new system improved drainage time by eight hours, clearing the dry dock of all water in 16 hours. This has increased production on the site because the overall turnaround time of ship repairs has been reduced. The drainage channel has also provided the customer with cost savings by decreasing electrical consumption and reducing pump hire fees,

As Holemasters Scotland completed its latest job at Rosyth Dockyard, the company launched a new eco-program called Leave Something for the Kids, designed to balance the carbon footprint left by the company’s work with environmentally-friendly action in the community. Holemasters calculated its carbon emissions for this job, then offset it by planting trees in the local area. It was calculated that 11 tons of carbon was emitted during the work, therefore 11 trees were planted. Kings Road Primary School in Rosyth was chosen to be the first organization involved in the program. David McArthur gave a presentation to students about ‘green’ thinking, and later that day the trees were planted in the school garden. Students then made posters that represented the aim of the program. For more information about the program, visit www.leavesomethingforthekids.co.uk.

equating to approximately £5,000 ($8,500) of savings every time the dock is emptied. Over a three-month period, including time for some additional tasks and snag items, Holemasters Scotland completed 1,288 meters (4,226 feet) of core drilling and created 176 linear meters (577 feet) of flat saw cuts before breaking and removing 356 tons of reinforced concrete. All work was completed as budgeted and within the specified time frame. “We were extremely satisfied with this project, as it proved that we execute large jobs in a safe and efficient manner,” said McArthur. “What was most pleasing, is that we performed so well despite only having a four-day lead time. The success of this job is testament to the hard work and professionalism of our team.” Dry Dock #3 at Rosyth Dockyard is now back in operation, complete with a new drainage channel. The methods used by this professional concrete cutter provided the necessary escape route for water in the dock and allowed the dock owner to make full use of this area— saving time and money.

CORE HEALTH
Does Your Favorite Healthy Snack Have a Dirty Secret? By Erin O’Brien
U
nless you grow and raise your own food, how do you know what ingredients are really in the food you are eating? Most of us rely on packaging to tell us what is in our favorite snacks and other foods. If we are trying to eat healthy, we look for things like “whole grain,” “fat-free” and “low-fat.” Healthy diets are made up of whole grains, low-fat foods and easy microwave dinners with healthy-sounding brand names, right? For the most part, this statement couldn’t be further from the truth. In the last issue of Concrete Openings, I discussed how some foods that have been marketed to the public as “bad for you” like bacon, eggs and butter are actually not so bad after all (Keep Calm and Eat Bacon!, June 2014). I would encourage you to go back and review that article, or read it for the first time. I also described how new research has proven that moderate amounts of the right kind of fats in our diets are not only ok, but actually good for us! Hopefully, many of you concrete professionals out there are now including bacon, eggs and butter into your weekly meal plans. This article, however, is addressing a different issue: foods that are labeled and marketed as healthy and good for you that actually are very unhealthy. The worst offenders are detailed below, but this is by no means an all-inclusive list. It is important to read labels carefully and pay attention to the ingredients listed, especially the first few. Ingredients on labels are listed by the amount contained in the product—the ingredients listed first tell you the primary ingredient in that product. VEGETABLE OILS In 1911, the process of turning liquid cottonseed oil into a solid was perfected and Crisco was introduced to the public. Initially, it was marketed as a healthy alternative to butter and lard because it was easier to digest, cleaner and more economical. The process that created Crisco is called hydrogenation and it takes saturated fats that, in moderation,
3 2 | S E PTE MBE R.14
are good for us and turns them into trans fats, which are not good for us and linked to a variety of diseases. Cottonseed oil is a vegetable oil. Other vegetable oils include canola, corn, sunflower and grapeseed. To produce these oils, the seeds are blasted with high heat and then mixed with solvents to extract the oil. Then, other chemicals are added to improve the color and odor. This process transforms the oil into polyunsaturated fatty acids (PUFA). Our bodies do not digest PUFAs well because our cells consist mostly of saturated and monounsaturated fats. These oils also have a high ratio of Omega-6 fats to Omega-3 fats, which creates inflammation within the body, raising a person’s risk of heart disease, obesity and diabetes. Coconut oil and olive oil are better options, although olive oil should not be cooked at high temperatures.
fats are filled with hydrogenated oils to maintain their shape and shelf life. The process makes the oil hard to digest and increases risk of cardiovascular disease. If you can’t believe it’s not butter, then you don’t want to know what it actually is. One excellent option is Kerrygold. It’s an Irish butter made with the milk from pastureraised, grass-fed cows and it is delicious.
SYNTHETIC OILS
Yes, both skim and low-fat milk contain fewer calories than whole milk, but they also have less saturated and unsaturated fat (which helps us feel full) and fewer fat-soluble vitamins like A, D, E and K. To make skim and low-fat milk, powdered milk is added to improve
If fat is bad, then fat-free oils and spreads are good, right? That what the people who make products like “I Can’t Believe It’s Not Butter” want you to believe. To make butterflavored spreads and margarine, fake oils and
WHEAT BREAD Many breads claim to be “whole wheat” or “multi-grain” while still using predominantly refined white flour. They can also contain partially hydrogenated oils, artificial sweeteners, high-fructose corn syrup, preservatives and food coloring. Look for the first ingredient to be “whole grains” or “whole wheat.” SKIM OR LOW-FAT MILK
consistency, because skim milk doesn’t resemble real milk when harvested. That process introduces oxidized cholesterol, which can damage your arteries. A 2012 study found that children who drank whole milk had lower obesity levels than those who drank skim or low-fat milk. MOST YOGURTS Many fat-free and low-fat yogurts have high-fructose corn syrup, sugar and starch added—some have as much sugar as a candy bar. Avoid yogurts with added fruit. This fruit is often soaked in sugar or from concentrate and has little to no nutritional value. Instead, buy plain, full-fat yogurt and add your own fruit. FAT-FREE ANYTHING To make foods fat-free, trans fats (the bad fats), artificial sweeteners and other chemicals are added to replace the fat and improve the taste. We’ve already discussed why fats other than trans fats are good for you, hopefully you understand why it is better to avoid fat-free foods. PROTEIN BARS These bars, designed to be either meal replacements, post-workout supplements or both, are high in sugar and high-fructose corn syrup. They also include a significant amount of trans fats and artificial sweeteners. While the protein content in these bars is commendable, the negatives outweigh the positives. SPORTS DRINKS They claim to quench your thirst and help keep you hydrated better than water. The truth is, no research has proven this to be true. High in sugar, calories, artificial colors and sweeteners, you’re better off with water unless you happen to be a professional athlete. In a pinch on a jobsite, these drinks can help keep an operator hydrate, but should not be relied upon on a consistent basis. FRUIT JUICES
vitamins and minerals are destroyed during production and synthetic ingredients are added to compensate. Stick with eggs, bacon, wholewheat toast and some fruit. Speaking of eggs… EGG WHITE-ONLY ANYTHING The egg yolk is the most nutritious part of the egg—skip it, and you are missing out on many vital vitamins and minerals. One egg, including the yolk, has about 80 calories— that’s less than a glass of fruit juice! DRIED FRUIT Think of dried fruit as candy with fiber. After the fruit is dried, chemicals and sugar are added to preserve flavor and extend shelf-life. Additionally, dried fruit has more calories per serving than fresh fruit. DIET SODA An occasional Diet Coke every now and then won’t kill you – but one every day might. New research proves that the artificial sweeteners, food coloring, preservatives and other chemicals in diet soda can cause heart disease in women. It’s not any healthier for men. Skip the soda for water, green tea or full-fat milk. While extensive, this list should not scare you away from trying to eat a healthy diet. Anyone in the concrete industry, especially those who spend a great deal of time in the field, should pay attention to what they eat. Added sugar, trans fats, artificial flavorings and colorings have all been proven to cause or contribute to a long list of deadly diseases, including heart disease, cancer, diabetes and obesity. Additionally, a poor diet containing large amounts of these ingredients can lead to decreased job performance. Focus on eating natural, fresh foods with ingredients that you can pronounce and recognize.

POLISHED PERSPECTIVE
The Architect’s Viewpoint: Specifying the Right Floor—Part I By Andy Bowman INTRODUCTION The challenge of protecting a concrete floor can be somewhat complicated. Depending on where the floor is, how it will be used and whether or not the coating or polish is new or a replacement, there is a wide range of choices available to a specifier. To make the right flooring system choices and get the best results from them, there are four key items to consider: • • • •
Selection of the appropriate flooring system Preparation of the concrete surface Installation of the flooring system Ongoing maintenance and protection of the flooring system
SELECTING THE APPROPRIATE FLOORING SYSTEM There are four factors that have a bearing on any choice of flooring: 1. Defining performance needs 2. Aesthetics 3. Production scheduling 4. Total cost Each choice has characteristics that will affect flooring system performance, eye appeal, timing and cost. 1. DEFINING PERFORMANCE NEEDS The single most important variable in choosing the right flooring system is defining the performance needs. For example, if an industrial floor needs to be washed, it probably shouldn’t become slippery when wet. Otherwise, the users of the floor will probably be unhappy no matter how nice it looks or how long it lasts. What needs should be considered? Key performance parameters will typically include: • • • • • •
Chemical resistance and/or anti-static performance Traffic conditions Wet or dry environment UV exposure Maintenance regimen Substrate condition
3 4 | S E PTE MBE R.14
CHEMICAL RESISTANCE AND/OR ANTI-STATIC PERFORMANCE In general, the thicker a flooring system is, the better its chemical resistance. It is important to recognize that chemicals used in a plant environment are rarely used alone. Therefore, a spilled chemical may react with other in-use or spilled chemicals to create a hazard far greater than either one alone. It is important to understand these potential interactions in order to choose the right containment lining and topping for the floor. Most suppliers test the resistance properties of their flooring products and are more than willing to provide this information. In many applications, the need for antistatic performance characteristics should be considered. Today, electrostatic discharge (ESD) is not only a significant cause of failures within the electronics industry, it also impacts productivity, product reliability, manufacturing profitability and safety in many other fields such as petroleum and chemical processing, munitions plants, textile, clean rooms and hospitals. TRAFFIC CONDITIONS Traffic and expected use are important considerations. Use of steel- versus rubberwheeled vehicles can affect the choice of aggregate, chemistry and method of application. “Traffic membranes” based on epoxy elastomers provide excellent impact and crack bridging capabilities for certain types of problem areas. Flexible epoxies provide much better impact resistance and wear capabilities than the traditional ¼-inch thick epoxy mortar systems. There are different traffic patterns in most facilities that can require different flooring systems. For example, aisles may receive polished concrete for heavy traffic, while workstations typically use coating systems. At the same time, battery-recharging stations might use a chemical resistant Novolac system. Careful selection is a way to meet budgets and still get the best possible performance. WET OR DRY ENVIRONMENT Where the flooring system is expected to be wet, some type of non-skid coating should be considered. The size and type of aggregate and topically broadcasted abrasive grit will dictate slip resistance in slurry and broadcast systems. However, the more slip resistant a
W WW. C O N C RE TE OPE N IN GS.COM
non-skid flooring system might be, the harder it will typically be to clean. A floor that will often be wet may also demand the application of an elastomeric epoxy membrane to create a fully waterproof floor. It is usually installed as an aggregatefree layer under a top layer. As an added benefit, this membrane serves as a crackbridging layer that provides advanced moisture control and protects the flooring system from slab movement. ULTRAVIOLET (UV) LIGHT EXPOSURE Epoxy floors will turn amber under sunlight or other artificial ultraviolet light. Of the chemistries used in seamless epoxy systems, a two-component acrylic urethane floor typically offers the best resistance to UV light. Polished concrete floor systems are very tolerant to UV exposure and will withstand daily exposure to direct sunlight. MAINTENANCE REGIMEN Flooring maintenance is an important consideration when selecting a system. Some cleaning agents contain strong oxidizing agents, strong acids or strong bases. Therefore, the maintenance department should have some input into flooring system selection. At a minimum, everyone should agree to the level of needed slip or skid resistance because slip resistance alters the ability to clean the floor. SUBSTRATE CONDITION The condition of the flooring substrate will have an impact on the choice of system. For every flooring system except coatings, the preferred method of surface preparation is an abrasive vacuum blast. The condition of the concrete floor can also affect the surface profile. For example, if the base cement has a very high water-to-cement ratio, then the surface will probably effloresce and be weak. An aggressive shot blast will create a much deeper profile than the same blast on sound concrete. In this case, or in the case of badly spalled concrete, a slurry or broadcast system may not hide the entire profile. Another substrate issue is the water content of the concrete (moisture migration). The concrete should not have more than 3% moisture (by weight) or release more than three pounds of water per 24 hours per 1,000 square feet. Exceeding these limits creates the risk of future floor blistering or other
bonding problems. Each material supplier will have a specific acceptable level of moisture transmission rate for their products, so check before specifying the floor system and do the necessary testing. 2. AESTHETICS Some performance characteristics limit the decorative options available. After first identifying the type of floor systems and required base chemistries, it is then time to consider what the finished floor should look like. Often this means simply choosing the desired color or using different colors to define traffic areas. Using different colors through the depth of the system is also an easy way to judge wear and schedule maintenance. When considering aesthetics, your options include color, design, gloss rating and finish texture. Not all chemistries are available in all colors. If safety and chemical resistance are the primary consideration, color and aesthetics are less of an issue. On the other hand, standard seamless flooring products are virtually unlimited in design characteristics. Pigmenting the epoxy matrix or using a clear matrix with colored aggregate achieves any flooring color. Combining these options allows for a variety of different finishes that can be manufactured to match any color desired. Color and design can be demonstrated best in thin-set epoxy terrazzo. Colored aggregates with an epoxy matrix yield a limitless color selection and divider strips form pictures and patterns. Other trowelled floors can also use divider strips for color patterns and designs. Polished concrete floor systems do offer color but continue to be challenged with offering a sustainable UV stable colorant. Integral colored concrete is the best viable option when coloring areas where polished concrete is specified.

SAFETY COUNTS
OSHA’s First Aid Requirements Can Sting By Mark A. Lies II, Kerry M. Mohan & Ilana R. Morady
U
nfortunately, accidents happen at work. No matter how thorough an employer’s training program may be and how much personal protective equipment an employer requires, employees still get injured. Because injuries happen at work, the Occupational Safety & Health Administration (OSHA) requires employers to make first aid and medical services available to their employees. This article addresses OSHA’s first aid requirements, issues employers may encounter with first aid and how first aid may implicate an employer’s recordkeeping obligations. FEDERAL OSHA REQUIREMENTS General Industry Requirements Under OSHA’s General Industry medical and first aid regulation, employers must ensure that either medical treatment for all injured employees is in “near proximity” or that a person at the workplace is “adequately trained
3 8 | S E PTE MBE R.14
to render first aid.” See 29 CFR 1910.151(b). In other words, if medical services (e.g. a hospital) are not close by, then employers must ensure that someone at the workplace has first aid training. Naturally, the most common question employers have is, “What is ‘near proximity?’” The answer is, it depends. OSHA takes the position that “near proximity” in cases of serious hazards and injuries—such as falls, suffocation, electrocution, amputation, cessation of breathing, cardiac arrest or uncontrolled breathing—means a 3-4 minute response time. For employers in lowerhazard settings, such as offices, OSHA has stated that a response time of up to 15 minutes could be acceptable. Thus, near proximity depends primarily upon what types of injuries an employer can reasonably expect in the workplace, but other relevant factors include the location of the workplace,
how much time it takes to reach medical attention, traffic and weather, geographic distance from medical care, travel distance from medical care, whether employees are provided with a means of calling for help in an emergency (e.g. a phone to dial 911), whether employees have a means of transportation available and whether the employer has notified or made arrangements with local emergency response units. Employers should consider what types of injuries could be reasonably anticipated at their worksites in addition to the other factors noted above. Part of this analysis can include evaluating OSHA 300 Logs and Worker’s Compensation claim histories at the worksite. If an employer determines that medical services are not in near proximity, then first aid training must be provided to ensure that someone with such training is available during all shifts.
First aid training is typically provided through organizations such as the American Red Cross or private institutions, and refers to medical attention that is typically administered immediately after an injury occurs. It usually consists of one-time, short-term treatment and requires minimal technology and training, such as cleaning minor cuts, treating minor burns, applying bandages and using non-prescription medicine. First aid does not include: • CPR, but many employers choose to offer CPR training. • Automated external defibrillators (AEDs), but employers should consider providing them in the workplace given their lifesaving capabilities. Moreover, Good Samaritan laws, as well as (in some jurisdictions) Worker’s Compensation laws, throughout the country serve to protect employees from potential liability in connection with the use of AEDs. If an employer chooses to provide an AED in workplace, they should be sure employees are trained on how to operate the device in accordance with state law. Regardless of the topics covered by an employer’s first aid training, employers should make sure training consists of documented written and practical tests. Employers should also ensure that first aid training is tailored to the worksite. For example, if employees work outside, then first aid training should include how to treat injuries arising from temperature extremes, such as how to respond to heat exhaustion and heat stroke. The training program should be periodically reviewed and updated with current first aid techniques and knowledge. Employers should remember that first aid certificates typically expire after several years. OSHA recommends that employees receive first aid training and knowledge re-training and updated certification cards every three years. OSHA’s General Industry medical and first aid regulation also mandates employers to ensure that “adequate first aid supplies [are] readily available” in the workplace. See 29 CFR 1910.151(b). Employers should be mindful that the meaning of “adequate” depends on the workplace. Accordingly, employers should evaluate the kinds of injuries that occur in their workplaces when deciding on the contents and quantity of materials in a first aid kit. Another important facet of first aid pertains to its location. The first aid kit must be “readily available,” i.e. easy to access in the event of
W WW. C O N C RE TE OPE N IN GS.COM
an emergency. This issue is often relatively simple at fixed facilities, but can become more complicated when employees work off-site or drive in company vehicles. In situations like these, employers cannot forget that a first aid kit should be “readily available.” Accordingly, if employers have, for example, delivery truck drivers, it is recommended that these employers equip their trucks with first aid kits. A question that many employers ask is how to prepare for injuries that may occur due to an employee’s pre-existing and/ or unknown health condition, such as an allergy, epilepsy or a cardiovascular condition. It is essential for employers to remember that requiring employees to disclose health information can run afoul of the Americans With Disabilities Act. Employers can, however, request employees to voluntarily inform their supervisors if they feel that they cannot safely perform a certain job or task because of a health condition, and also to immediately report when they feel ill or have been injured. Volunteering this informationcan help employers pre-plan for potential emergencies. If employers encourage self-disclosure, they should be mindful to avoid asking employees about the actual health conditions beyond what is necessary to take action to protect the employee’s health and safety.
However, unlike the General Industry standards, the Construction standards requires that the first aid materials be: (a) stored in a “waterproof container;” (b) each item contained in the container is individually sealed; (c) the employer checks the first aid kit every time the kit is sent to a worksite; and (d) while on the worksite, the first aid kit is checked at least weekly to ensure used items are replaced. See 29 CFR 1926.50(d)(2). The Construction standards also require that when an employer is unable to contact an ambulance service, the employer must provide equipment for the “prompt transportation” of an injured person to a physician or hospital (i.e., backboard and vehicle). See 29 CFR 1926.50(e). Further, on worksites where employees may be exposed to corrosive materials, the employer is required to provide “suitable facilities” for the quick drenching or flushing of the eyes and body for immediate use. See 29 CFR 1926.50(g). Thus, the question is what is a “suitable facility?” In short, if the facilities are insufficient to treat an exposed employee for the particular corrosive materials, the facilities are non-compliant. STATE-SPECIFIC REQUIREMENTS
In addition to Federal OSHA’s first aid requirements, employers must be aware of state-specific requirements that may impose CONSTRUCTION REQUIREMENTS additional obligations upon employers. For instance, under California OSHA’s General OSHA’s Construction standards require Industry Safety Orders, an employer’s first aid many of the same first aid requirements materials must be “approved by [a] consulting discussed above. For instance, the physician” and that approval must be in Construction standards require that an writing. See Cal-OSHA GISO § 3400(c). Thus, employee at the worksite be trained in first Cal-OSHA requires employers subject to its aid when medical care is not “reasonably General Industry Safety Orders to “consult” accessible.” See 29 CFR 1926.50(c).The with a physician in evaluating what materials to Construction standards also require that first include in their first aid kits. aid materials be “easily accessible.” See 29 CSU-201408-Con Open 1-12 ad_Layout 1 7/8/14 11:44 CFR 1926.50(d)(1).

Employers must also be wary of what materials they include in their first aid kits. For instance, many employers make available to employees single-dose medications (i.e., Tylenol or Advil). However, under Cal-OSHA’s Construction Safety Orders, if an employer has more than basic first aid equipment in its first aid kit (i.e., bandages), such as “drugs, antiseptics, eye irrigation solutions, inhalants, medicines or proprietary preparations,” that additional equipment must be approved, in writing, by an employer-authorized licensed physician. See Cal. Osh. CSO § 1512(c)(3). These are just two examples of state-specific requirements that employers may face with regards to their first aid kits. Accordingly, employers should evaluate what states they do business in to determine what additional requirements, if any, they must follow to avoid potential liability. FIRST AID AND OSHA RECORDKEEPING Employers should be aware how the type of first aid or medical treatment provided to employees can implicate their recordkeeping obligations. OSHA requires employers to maintain OSHA 300 Log, and supporting 300A and 301 documents for all work-related illnesses and injuries. Relevant to the current discussion, OSHA deems a work-related injury or illness to be recordable, in part, when the employee receives medical treatment beyond first aid. See 29 CFR 1904.7(b)(1)(iv). Though OSHA’s recordkeeping regulations define the terms “medical treatment” and “first aid,” the distinction between the two can be confusing. For instance, suppose an employee injures his or her knee while on the job and sees the company nurse or physician. If the medical professional

gives the employee “a non-prescription medication at non-prescription strength” (i.e., two Tylenol pills), then that would be considered first aid and the injury would not be recordable. However, if the medical professional gives the employee three Tylenol pills instead of two, OSHA may find that the employee received “medical treatment” because the employee received a “prescription strength” dose. Other examples where the line between “first aid” and “medical treatment” can be crossed include: •
The use of oxygen, even if precautionary;
•
The use of numbing or antibacterial eye drops;
•
The use of certain skin creams;
•
The use of rigid versus non-rigid splints; and
•
The use of medical glue to close a cut.
RECOMMENDATIONS To avoid potential liability related to first aid, an employer should consider the following actions: • Conduct a job hazard analysis of the facility or worksite to determine what hazards exist and what injuries or illnesses could arise; • Once the job hazard analysis has been completed, consider what type of first aid materials should be maintained at the facility or worksite; • If the employer is located in a state that requires physician consultation, consult with a physician regarding what materials should be included in the first aid kit and obtain verification of that consultation in writing; • Evaluate what medical services are reasonably accessible to the facility or worksite. If medical services are not reasonably accessible, the employer should provide documented first aid training to a select group of employees at the facility or worksite and ensure coverage throughout the entire workday, including the off-shift; • Develop a written procedure that documents the company’s first aid procedures and mandatory employee first aid training and re-training; • Ensure that the first aid certifications of the first aid providers are current; and • Evaluate the type of treatment employees receive in response to a work-related injury to evaluate whether the injury must be recorded in the OSHA 300 Log and supporting 300A and 301 documents. If an employer undertakes these actions, it will minimize its potential liability as it relates to first aid and its implications. Mark A.

A MONUMENTAL TASK Famous Sculptures Cut and Removed from Olympic Trail
T
he construction of an elevated toll highway in Mexico City required the removal of ten large reinforced concrete sculptures, measuring between 7 and 22 meters tall (23 and 72 feet), from the roadside of an existing highway. The sculptures were over 40 years old and had become synonymous with the city, so a solution was needed to remove and relocate them without impacting their structural integrity. The ten sculptures were part of a larger collection of 22 designed by several artists from five continents. They were installed in 1968 as Mexico City prepared to host the 19th Modern Olympic Games. This was the first time the international event had been held in a Latin American country. The 22 sculptures were positioned along an 11-mile stretch of road named “La Ruta de la Amistad” (Friendship Road) that led to the Estadio Olímpico Universitario (University City Stadium), the official Olympic stadium for the games. During the decades that followed, however, the novelty of the sculptures began to wear off and some had fallen into disrepair. It was in the 1990s that the Board of the “Ruta de la Amistad” was formed, with the aim of maintaining and improving the road through the involvement of private initiatives. Some of the sculptures have since been restored, but in 2012 it was deemed necessary to relocate ten of them so that a new elevated toll highway could be built.
A total of 22 sculptures once stood along the Ruta de la Amistad (Friendship Road).

Cutting the reinforced concrete structures with diamond tools provided low levels of noise and eliminated vibration, so CSDA member ADRA Ingenieria, S.A. de C.V. (ADRA) of Leon, Mexico, was contracted by Cav Diseño e Ingenieria S.A. se C.V. to remove three of them. The specialty contractor would remove “Señales” (Signs) by Mexican artist Ángela Gurría, “El Ancla” (The Anchor) by Willi Gutmann of Switzerland and “Las Tres Gracias” (The Three Graces) by Czech artist Miloslav Chlupac. The contractor was responsible for creating openings in each structure to review its composition, engineering and installing steel support frames to house the structures during removal and transport and executing a series of planned cuts to free each one from the ground. Due to the job being located on a major route around Mexico City, work had to be performed at night or when highway construction crews scheduled lane closures during the day. Construction of the new highway was progressing fast, so ADRA had to mobilize quickly. As well as being supervised by the general contractor, the cutting team would be working under the watchful eyes of the international media. The Ruta de la Amistad sculptures were included on the World Monuments Fund’s 2012 Watch List, so each step of their safe removal and restoration was being documented. Formed in 1965, the World Monuments Fund is the leading independent organization dedicated to saving the world’s most treasured places. The organization provided funding to restore three of the 22 sculptures last year. These works of art were constructed decades earlier and any mechanical data about them could not be found. In lieu of any blueprints for the sculptures, the cutting contractor had to create openings to figure out what type of reinforcement had been used, The contractor was tasked with cutting three large statues for removal.

Gas-powered hand saws were used to create small openings in the structures to inspect their construction. where it was located and what type of aggregate was utilized. It was also important to determine if they had been constructed using one or multiple support structures. The results of these inspections would also help in choosing the right type of vehicle to transport the sculptures when they were cut free and secured in steel frames, as their exact weights were unknown. First, the team from ADRA set up a work area at the location of Las Tres Gracias. The sculpture consisted of three 15-meter (42-foot) tall columns, two pink and one purple in color, with some undulating
edges. Operators used a K 1250 gas-powered hand saw and other cut and break tools from Husqvarna to create a 30- by 30-centimeter (11.8- by 11.8-inch) opening in the concrete to inspect the structure. It was then discovered that the columns were hollow and the walls were only 8 centimeters (3.1 inches) thick, with a steel support running through each one to maintain structural integrity. This also turned out to be the case for the other sculptures. Custom steel frames were engineered and installed around each column before cutting commenced. The contractor was able to set up

one wire saw cut at the base of each column to penetrate the concrete surface and separate the steel support structure from the ground. A Husqvarna CS 2512 wire saw with a 15-meter (42.2-foot) length of 40-bead diamond wire was used to make the three cuts, each taking four hours to complete. Wedges were periodically installed in the cut line to avoid the wire getting stuck. SeĂąales stood 18 meters tall (59 feet) and was the closest of the 22 sculptures to the Estadio OlĂmpico Universitario. Two horn-like structures, one black and one white, stood parallel to each other approximately 1.5 meters (4.9 feet) apart. This was the most complicated sculpture to move because of the shape of the two pieces. The base of each horn was 3 meters (9.8 feet) wide by 18 meters (59 feet) long but reduced to 60 centimeters (2 feet) by 1.2 meters (3.9 feet) in size at the top. It was deemed too risky to remove and transport them in their entirety because of potential breaks, so they were each cut into three 6-meter-tall (19.7 feet) pieces to be rejoined later. Scaffolding was set up against the steel frames and the top section of each horn was removed using hand saws, taking two operators three hours to cut. The process was repeated for the two middle sections before a Hilti TS5 track-mounted wall saw was used to make vertical cuts on the larger, bottom sections that remained. These cuts

were necessary to introduce a metal joint and help secure the sections during transport. This last set of cuts took operators 10 hours to complete. La Ancla proved to be the easiest of the three sculptures to remove. The team from ADRA dug out the ground surrounding the artwork and found that it was supported by four bars of steel rebar, which were cut using cutting torches. Just like the other sculptures, La Ancla was placed in a steel support structure and transported to a new location. These three sculptures were removed over three weekends, with cutting teams working from 11:00 PM to 5:00 AM each night in line with road closures. Cut sections were rigged and placed on lowboy trailers by crane, then transported to a temporary restoration area nearby. As anticipated, the use of diamond tools provided clean cuts and minimal damage to the sculptures, allowing swifter repairs and relocations. The sculptures are now located close to the Aztec Stadium—the city’s main venue for soccer that is a few short miles from La Ruta de la Amistad. “The complexity and conditions made this a very challenging job. The dimensions of each sculpture was different, so we needed to use several tools to complete our tasks. I am pleased that ADRA has helped to preserve these sculptures so they may be enjoyed by future generations,” said Raul Bracamontes, owner of ADRA.

ecently, Indiana Flooring Carpet One was contacted by a couple that had just bought a home in Madison, Indiana, and wanted to discuss flooring solutions. The couple had a growing family and had been searching for a larger property in the country. They had found their dream home, but it was in need of some major remodeling work— including new floor surfaces.

A hard-wearing surface was needed at a home in Madison, Indiana.
The company is a CSDA member and part of the association’s Polishing Committee. Mike and Tony Jackson are the co-owners and the company services residential and business properties in central Indiana. In addition, the company has commercial and national accounts that cover the entire Midwest. The couple contacted Indiana Flooring Carpet One and worked with the contractor to find the right type of flooring to meet their needs. While the upstairs floor of the house was to have natural hardwood floors, a more hard-wearing material was desirable for the 1,000-square-foot ground floor. This part of the house was earmarked as a recreational room and hang out area for the couple’s four growing boys. The family loved the outdoors

and regularly went hunting and fishing, plus the four sons were tough on just about everything, so the couple were looking for recommendations of a surface that could stand up to some harsh treatment while being easy to maintain. There were many options available, but Indiana Flooring Carpet One suggested that a dyed polished concrete floor would be the most suitable surface and recommended the CRMX polishing system from CSDA member GMI Engineered Products. This was the company’s go-to system and had been used several times before to successfully create high-quality polished floors. “We are certified applicators of this system and have found it to be the best one

for polished concrete floors. We worked with the customer to decide which color dyes to use. In the end, we settled on two shades of black that gave the floor a variegated look,” said Tony. The 1,000-square-foot work area was approximately 39 feet by 28 feet, so the floor was rectangular in shape except where a stone fireplace protruded from the middle of one wall. Fortunately, Indiana Flooring Carpet One was the first contractor to do work in the room, so the polishing process could be completed without the concern of impacting other work—particularly wall finishes. First, the black rubber-back carpet was removed before a 19-inch concrete grinding machine with carbide scraper blades was used to remove
an alcohol-based adhesive. The operator then used an HTC 800 to cut the adhesive residue with 40 grit metal bond diamonds, taking two passes to get below the residue and leave a clean slab surface. This left the surface with what is known in the industry as a ‘salt and pepper look,’ meaning the equipment had reached a layer of coarse sand and cement where flecks of sand become visible in the polished surface. The application of a surface refining agent was the first step in the CRMX process, which removed all scratches and produced a high level of clarity in the floor. This was followed by the use of a segment canvas setting tool that, when used in conjunction with a refining agent, further refines the

The contractor used two models of burnishers to finish the entire area. surface. Then, the operator applied the two acetone dyes with a pass of resin over each. After all residue from the dye was cleaned off, a densifier was put down to harden the concrete and create a dust-proof surface. The final step was to polish and burnish the floor using a 27-inch propane burnisher and a 17-inch electric burnisher for areas that were harder to navigate. The result was a highly-reflective, even-finished floor. “The customer had looked at some of our projects around town but could only imagine how the floor would turn out after polishing. When it was completed, the couple told us they had no idea it would turn out so well and were 100% satisfied with our work. It was very pleasing to hear that we had exceeded their expectations,� concluded Tony.

Noise Levels of Diamond Blades By Anthony Baratta
I
n the United States, the Occupational Safety and Health Administration (OSHA) and the Mine Safety and Health Administration (MSHA) set legal limits on noise exposure in the workplace. These limits are based on a worker’s time weighted average over an eight-hour day. The Canadian legal limits fall under the jurisdiction of the Canadian Centre for Occupational Health and Safety (CCOHS). Noise is measured using a weighted scale. Sound levels are measured in units of sound pressure levels called decibels (dBA). The A-weighted sound levels closely match the perception of loudness by the human ear and are the scale used by most enforcement organizations. Decibels are measured on a logarithmic scale, which means that a small change in the number of decibels results in a huge change in the amount of noise and the potential damage to a person’s hearing. With noise, OSHA’s permissible exposure limit (PEL) is 90 dBA for all workers for an eight-hour day. The OSHA standard uses a 5 dBA exchange rate. This means that when the noise level is increased by 5 dBA, the amount of time a person can be exposed to this noise level and receive the same dose is cut in half. In addition, the National Institute for Occupational Safety and Health (NIOSH) has recommended that all worker exposures to noise should be controlled below a
level equivalent to 85 dBA for eight hours to minimize occupational noise induced hearing loss. NIOSH has found that significant noise-induced hearing loss occurs at the exposure levels equivalent to the OSHA PEL based on updated information obtained from literature reviews. NIOSH also recommends a 3 dBA exchange rate so that every increase by 3 dBA doubles the amount of the noise and halves the recommended amount of exposure time. The following study was performed to give insight into the current core technology that is available in today’s marketplace and help contractors meet noise level regulations enforced by OSHA, MSHA and CCOHS. Several different blade types and designs have been tested, complied and compared for noise, stiffness and deflection versus applied load. This helps when choosing the right type of core for a particular application. Sound pressure level tests were performed using an A-scale microphone that was positioned 12 inches away from the sample and aligned with the arbor center. Frequency (Hz) and sound pressure level (dBA) were recorded and plotted utilizing a 1/3 octave realtime spectrum analyzer by Audio Control Industrial Model: SA3052.

OSHA/CSDA Alliance Latest The Alliance between CSDA and the Occupational Safety and Health Administration (OSHA) is now in its eigth 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.
UPDATED WEBSITE, TRAINING RESOURCES LAUNCHED FOR CONSTRUCTION DEMOLITION INDUSTRY On June 20, a construction worker taking down an old building in New Jersey was trapped and killed when the last standing wall of a building under demolition collapsed on top of him. Six months earlier, a 25-year-old construction worker in Chicago was struck and killed by pieces of falling concrete while conducting renovations on a shopping mall. To help prevent these tragedies and save lives, OSHA recently launched an updated demolition website to address the hazards common in demolition operations
W WW. C O N C RE TE OPE N IN GS.COM
and the safety measures that can be taken to prevent them. The updated Demolition page provides information on applicable OSHA standards, hazard assessments, measures that can be taken to prevent injuries and illnesses before site work begins, and a link for stakeholders to share stories about demolition safety. From 2009 to 2013, OSHA issued nearly 1,000 citations for violations of OSHA’s construction demolition standards. The most common citation issued was for failure to conduct an engineering survey to determine the condition of the structure prior to demolition. This includes determining whether an unplanned collapse of the building or any adjacent structure would injure those working in the vicinity. For more information, visit www.osha.gov.

CS Unitec Introduces AirPac The AirPac from CS Unitec removes condensation and dirt from air lines and protects pneumatic tools from rust and premature wear. The AirPac automatically removes water and contaminants from the compressed air in the system and sends clean, dry, lubricated air to the tool. The AirPac weighs 40 pounds and has valves for connecting up to two air tools. It has a built-in oiler, which holds a half pint of air tool lubricant. In very cold environments, use of anti-freeze air tool lubricant prevents tools from freezing up. As compressed air leaves an air compressor, it expands and vapor in the air line can condense into water. The moisture in the air line can cause rust to develop in the air tool motor. AirPac collects 99% of the water and any dirt in its interior baffle before dropping it into a holding tank. This results in clean, dry, lubricated air being sent to the tool. The AirPac’s float valve automatically ejects the accumulated water and dirt when the tank is full. For More Information Tel: 800-700-5919 Web: www.csunitec.com

NEXT GEN
CSDA NEXT GENERATION GROUP The group aims to continue the growth of the association while serving the needs and wants of the younger generation, with the goal of continuing to set a standard of excellence.
TESTIMONIAL MG Concrete Cutting & Coringwas originally established in 1974 and specialized in commercial construction material distribution, including rebar fabrication/detailing, as well as concrete equipment rental. From the time JD Munley purchased the company in 2003, the search began for a fourth “leg” to the stool that would provide stabilization when the construction market was soft. The concrete cutting industry seemed to fit all of our requirements without stepping on the toes of any of our customers, so in late 2006 we formed M6 Concrete Cutting & Coring. As in our core industry, we looked for professional organizations that would assist us with knowledge and expertise Jamey Johnston in this specialized M6 Concrete Cutting & Coring field. We joined CSDA Wichita, Kansas jameyj@conacc.com and immediately felt the benefits of this organization. From Operator Certification to Toolbox Safety Tips, we have found great value from top to bottom. Above and beyond the membership benefits is the comradery and respect given from other members. Members of CSDA are helpful in every aspect of our business, and are willing to help insure success. CSDA is much more than an industry status, it is a group of partnerships that continually strive for the success of its members.

DIRECTOR’S DIALOGUE
Is CSDA for Everyone?
PATRICK O’BRIEN Executive Director
T
his is a question that we, the association, try to address whenever a new benefit, program or product is launched. While we would like to think the answer is a resounding “yes,” we know that some do not share this view. The question is one of several that is often discussed by CSDA’s Board and committees as they try to find new ways and methods to serve the needs of the industry—particularly contractors. Many individuals and groups are very supportive of CSDA, but there are also people who just do not think the association is right for them. CSDA cannot be all things to all people, but its Board, Officers and staff can listen to both those that support CSDA and those that do not in order to create a better association. In July, I gave a presentation to the sales team of a CSDA manufacturer member. The reason to take advantage of this opportunity, was because people on this sales team visit contractors almost daily, both members and non-members. These sales people were presented with information about the benefits of CSDA membership and are now well informed to relay this information to their customers. This could encourage more contractors to learn more about what the association can offer them. Some of the sales team already knew about CSDA’s member benefits, but others were not fully aware of what is offered— especially those that could aid contractors improve or expand their businesses. It was equally important that I listened and learned from these sales people. While CSDA may have done a good job of
7 2 | S E PTE MBE R.14
developing benefits for members, we may not have done as good of a job when it comes to communicating these benefits to members and prospects. In addition to better educating those in the industry about CSDA benefits, there are undoubtedly other benefits that the association could develop and offer. I recently talked to an industry professional who heads up a group of operators. This group felt that CSDA was an association for only owners and managers, and that the voice of the operator was not being heard. Several suggestions were made to address their needs, including a committee and Board seat if they would like to explore working more closely with CSDA. In my opinion, the CSDA Board and Officers would be very willing to consider such a change and better recognize the many operators in the industry. We will continue to listen and learn from these operators. The benefits of CSDA membership are detailed on www.csda. org. These are many, and more than I could discuss in this Director’s Dialogue. Please take a moment to review these benefits. Nearly all of them were developed as a result of requests by contractors seeking assistance with their businesses, but that is not to say we have addressed every need out there. Your input as to what CSDA can do to better serve the industry is very much appreciated. Feedback is welcome—good or not so good. Please call me at 727-577-5004, email me at pat@csda.org or contact a Board member (see page 3). If you feel that CSDA is not for you, then let us know how we could change that.
