hope all of our members—contractors, manufacturers and affiliates—have had a busy and profitable summer season. The summer months are the time of the year when we find ourselves most pressed for time and, as a result, often forgo some tasks we feel are secondary as we strive to ‘get the work done’. However, there is one critical issue that may have been placed on the backburner during the height of the busy season that needs to be addressed NOW. This critical issue is, of course, the new OSHA silica standard, which came into effect March 2016 and will be actively enforced by the Administration nationwide from September 23rd. I am sure everyone is aware of the new OSHA standard, but may not be sure how to incorporate it into their current practices and procedures. In order to comply with the new standard, your company will need to implement items such as a written Exposure Control Plan, analyze Table 1 of the OSHA rule for operating tasks, designate and train a ‘competent person’ or persons, provide medical surveillance, implement proper documentation and train employees on silica exposure. CSDA has many valuable resources to inform and assist member companies with implementation tasks necessary to be in compliance with the new OSHA rule. Documents and articles providing useful information can be found at csda.org/silica, including notes from a silica panel discussion held at the last CSDA Convention, silica-related articles published in Concrete Openings, a PDF copy of the OSHA rule (including Table 1) and other helpful resources. Our manufacturer members are also available and willing to provide assistance and information on their products to help companies stay in compliance with the new rule.

In addition, OSHA has resources available to help companies comply with the new rule, including Table 1 and the Small Entity Compliance Guide for the Respiratory Protection Standard. For these and more resources and information, go to osha.gov. It may seem difficult, tedious and somewhat overwhelming to adapt company practices and procedures, especially during what is, for many, a busy year. However, compliance will provide a higher level of safety and documentation that ultimately benefits our employees and customers. As a professional organization, our members are more than capable of following the new rule and setting a strong example for the rest of the industry. During the creation of these new silica regulations, CSDA worked to inform OSHA about the concrete cutting industry and how best practices endorsed by CSDA have reduced silica exposure to cutters. CSDA will continue to lead the way to help members comply with the new regulation and communicate the needs and opinions of the industry to the Administration. In related news, CSDA’s Certification Committee is finalizing an improved process for Company Certification and this program will commence this year. Please review the information at csda.org/ certification and consider submitting an application. This program will help you comply with the silica standards as well as other important safety and business requirements. Finally, registration for our 2018 Convention & Tech Fair will open very soon. Please consider joining us March 6–10 at the Grand Wailea in Maui, Hawaii for this exciting and informative gathering. Visit csda. org/convention for the details. We expect it to be a popular, fun and successful event. I hope to see you there. Aloha!

Chicago Riverwalk Expansion Out-of-the-Box Creativity Gets the Job Done
A
professional concrete sawing and drilling contractor employed a custom-engineered saw system to complete over 600 linear feet of challenging horizontal cuts on the City of Chicago’s high-profile Riverwalk project. This specialty cutter was tasked with cutting and removing a stretch of damaged curb measuring 10 inches wide and just 5 inches tall completely flush with the rest of the deck surface.
The Chicago Riverwalk is located on the south bank of the Chicago River in the downtown area of the city. Spanning 1.2 miles from Lake Shore Drive to Lake Street, the project was originally developed in the 1990s as an initiative to reclaim this stretch of the river for the ecological, recreational and economic benefit of the city. As part of two new phases of expansion work on the initiative, general contractor Walsh Construction needed to complete the construction of a new pedestrian ramp to connect the upper and lower levels of the Riverwalk close to Wabash Avenue. The old damaged concrete curb was removed so that a new one could be poured. An Internet search led the general contractor to a solution provided by an Indiana-based CSDA member, and the cutting contractor was subsequently selected to do the work. However, even this
specialty diamond cutter knew the job was no easy task. “The concrete was heavily reinforced with steel rebar,” said John Baaske, owner of CSDA member Northwest Indiana Concrete Cutting in Schererville, Indiana. “What made things worse was that some of this rebar was positioned horizontally at the exact elevation of the flush cuts. Therefore, roughly 60% of the work involved cutting through the lengths of the rebar rather than through the diameters.” Sawing through so much steel is not uncommon for contractors like Baaske, but this particular flush cutting task was made even more challenging because the height of the curb was not tall enough to attach any track-mounted equipment. With 600 linear feet of reinforced concrete to cut, attempting to do the work with a hand saw

was not feasible either. Therefore, Northwest Indiana Concrete Cutting had to come up with a way to cut the specified length of the 10-inchthick, 5-inch-tall Chicago Riverwalk curb with the accuracy and efficiency of a track-mounted unit, but without anything to attach it to. Challenging situations like this in the past had led Baaske to invent and fabricate the All Terrain Concrete Saw attachment, which is now manufactured and sold by JS Innovations. The 700-pound, hydraulic-powered attachment was designed to fit on the company’s 25-horsepower skid steer, providing a stable yet maneuverable piece of equipment to create the flush cuts without having to mount a saw. It was also made with an articulating head, meaning the contractor could flip it 180 degrees to perform flush cuts on the inside or outside of curbs. The saw’s 5,000 psi motor could easily accommodate a 28-inch-diameter blade, supplied by Husqvarna Construction Products, to make the 10-inch-deep cuts. Additionally, the attachment was small enough to be lifted onto the pedestrian ramp, as there was no final connection from the upper sidewalk to the ramp. Neither was there a connection from the other end of the ramp to the lower level below. It was essentially a freestanding structure at the time the cutting work was completed. Aside from the
tricky access, the width of the ramp was only 8 feet so the contractor needed to work in a small footprint with a five-day schedule set by the general contractor. Northwest Indiana Concrete Cutting mobilized and began setting up the work area on the Chicago Riverwalk. The All Terrain Concrete Saw attachment and skid steer were lowered onto the pedestrian ramp deck separately by crane before the operator was transported there too. Prior to this, the general contractor erected temporary construction railings on the ramp to prevent falls. With both pieces of equipment positioned in the work area and the diamond blade mounted on the saw, the attachment and skid steer were connected and the contractor was making cuts within 10 minutes. Saw cutting started at the upper end of the ramp and moved from west to east as the contractor worked down to the lower level. The operator of the cutting machine had to perform approximately 50 linear feet of radial flush cutting in line with the curvature of the ramp, while the remaining 550 feet was straight. To allow for wet cutting, water was pumped from the Chicago River and through the attachment to the cut, but Baaske’s machine was also designed to draw water from tanks mounted on the skid steer. After completing two to three linear feet of

curb cutting, a sledgehammer was used to break off the cut pieces and all concrete was removed from the jobsite by Walsh Construction. Over five shifts, the concrete sawing operator used the customfabricated saw system to cut 600 linear feet of reinforced concrete curb flush to the surface of the existing ramp, leaving a clean, smooth surface for the general contractor to pour the new curb. The operator used the saw to follow tight to the curved portions of the curb without interrupting cutting progress. Once completed, the attachment and host machine
The saw attachment was connected to a skid steer to perform cutting tasks.
Chicago Riverwalk Expansion Once a meandering marshy stream, the Chicago River first became an engineered channel to support the industrial transformation of the city. Following the famed reversal of the river, in which the city reversed the flow of the Main Branch and South Branch to improve sanitation, architect and urban planner Daniel Burnham introduced a new civic vision of riverside promenades with the addition of the Wacker Drive viaduct. This vision gave birth to the Chicago Riverwalk project. In 2012, a team of architectural and engineering firms, supported by technical consultants, was tasked with completing the vision for phases two and three: six blocks between State Street and Lake Street. Building off the previous studies of the river, the team’s plans provided a pedestrian connection along the river between the lake and the river’s confluence. The task at hand was technically challenging. The design team needed to work within a tight permit-mandated 25-foot-wide build-out

area to expand the pedestrian program spaces and negotiate a series of under-bridge connections between blocks. Further, the design had to account for the river’s annual flood dynamics of nearly seven vertical feet. Now, with new connections that enrich and diversify life along the river, each block takes on the form and program of a different river-based typology. These spaces include: The Marina Plaza: Restaurants and outdoor seating provide views of vibrant life on the water, including passing barges, patrols, water taxis and sightseeing boats. The Cove: Kayak rentals and docking for human-powered crafts provide physical connections to the water through recreation. The River Theater: A sculptural staircase linking Upper Wacker and the Riverwalk offers pedestrian connectivity to the water’s edge and seating, while trees provide greenery and shade. The Water Plaza: A water feature offers an opportunity for children and families to engage with water at the river’s edge. The Jetty: A series of piers and floating wetland gardens offers an interactive learning environment about the ecology of the river, including opportunities for fishing and identifying native plants. The Boardwalk: An accessible walkway and new marine edge creates continuous access to Lake Street and sets the scene for future development in this critical space at the confluence.

were detached from each other and lifted by crane back to street level so they could be placed on the contractor’s work trucks. Baaske was pleased with how the saw performed. “I was extremely satisfied with the saw attachment. The placement of the rebar in the curb was an extra challenge, but the saw handled it well. This was the only machine I felt could do the job at the production level that was needed. A hand saw would not have had the capacity or production output required to cut the specified length of the 10-inch-wide and 5-inch-tall curb. Plus we had no easy way to position ourselves on the outside of the curb to complete the cuts from that angle.” Baaske continued, “The time taken to break down the attachment and skid steer, move the equipment to the jobsite and reassemble on the ramp was around 30 minutes. We were spinning blades and cutting immediately after. The All Terrain Concrete Saw can cut anywhere from -5 degrees to 90 degrees, and as high as its host machine can reach. Through further development with JS Innovations, we have also used it on projects were we have spun a 42-inch-diameter blade.” Phases two and three of the Chicago Riverwalk expansion, which included the work done by Northwest Indiana Concrete Cutting and the All Terrain Concrete Saw attachment, were completed and opened in October 2016. The Riverwalk now spans over nine blocks along the Chicago River and is enjoyed by thousands of city residents and tourists each day.

n the banks of the Willamette River at a bustling port in Portland, Oregon, a Ground Penetrating Radar (GPR) analyst and a core drilling operator inspected a series of reinforced octagonal concrete piles and drilled cores for crucial structural integrity tests on an aging pier.
CSDA Member Penhall Technologies, based in Anaheim, California, was contacted by a large construction and engineering firm to inspect nine octagonal piles on a pier at Terminal 5 of the Port of Portland. The piles had been in place for over 40 years and testing was necessary to ensure the pier remained structurally sound. While it was known that the piles contained reinforcing steel rebar, their complete makeup was unknown as was the condition of the concrete below the surface. It was specified by the construction company’s project engineer that any reinforcing rebar or vertical pre-tensioned cables within the structures

not be disturbed while core drilling, so a non-destructive method was needed to identify hidden objects. “Gone are the days of crossing fingers in hopes that no subsurface hazards or embedments are struck. GPR scanning takes the guess work out and allows for project efficiency,” said Colby Bruni, Penhall Technologies’ GPR analyst for the job. Conditions were far from perfect for this type of inspection. The job was scheduled during the month of January when average daily temperatures in Portland are in the low 40’s. The GPR analyst and core drilling operator were out on the water performing their tasks from a floating work barge with no shelter from the elements. Despite the cold weather, the pair were equipped to get to the jobsite and produce accurate results for the customer. After the two-man crew arrived at Terminal 5 with all equipment needed to complete the task, they set out on a work barge to the first scan location. The floating barge had to be positioned 40 feet from

the pier deck because the water around the pier was not sufficiently dredged, so a telescopic boom lift was employed to position the analyst and operator next to the piles. The GPR analyst scanned each of the 2-foot-wide, 2-foot-thick octagonal concrete piles using a Mini HR GPR unit from CSDA member GSSI, Inc. Using a 2,600 megahertz antenna, this piece of equipment provided data that allowed the Penhall Technologies analyst to analyze and identify embedments and hidden objects within the concrete. The unit is designed for the subsurface location of rebar, conduits, posttensioned cables and voids. Imaging the piles was achieved by sending radar waves from the GPR unit through the concrete piles themselves. When the waves are sent through an area or structure, reflections are produced. This occurs when the wave itself enters into a material with different properties than that of the material it initially left. The series of waves over a specific area make up the scan image. From this image, and through observations of both structural surroundings and the structure itself, the analyst was able to determine the type of embedments encountered by the wave and at what depth the material was positioned in the concrete.
For this particular job, the Penhall GPR analyst used the Line Scan method to collect and analyze the data. A Line Scan is when data is collected by passing the radar antenna or antenna array over the concrete to image targets as a cross-sectional view. This method requires scanning and marking targets as they are revealed in each line of data. The scan face of the pile was 10 inches wide and the analyst scanned a 2-foot-tall section. Scan results indicated that there were two pre-tensioned cables and spiral rebar within each hollow pile. Objects located by the GPR equipment were presented on the display and subsequently marked on the concrete pile in colored lumber crayons.

The Port of Portland In 1891, the Oregon Legislature created the Port of Portland to dredge and maintain a shipping channel from the city of Portland to the Pacific Ocean. The Port owns four marine terminals, including Oregon’s only deep-draft container port, and three airports. It also manages five industrial parks around the metropolitan area that are home to more than 400 companies. The Port of Portland has created nearly 27,000 jobs in the Portland metro area and generated almost $1.8 billion in total income for the region, based on 2015 figures. The Port’s terminals cover 892 acres, used to handle mineral bulks, motor vehicles, liquid bulks, food stuffs, manufacturing materials and shipping containers. In 2015, the Port handled approximately 8.5 million tons of cargo. It is the largest wheat export port in the U.S. and the largest mineral bulks port on the U.S. West Coast. The GPR analyst scanned 2-foot-wide octagonal piles and marked the findings on the concrete.

The team worked from a telescopic boom lift from a floating work barge to access the piles.
Based on the data collected by the GSSI unit and the interpretations of the GPR analyst, the Penhall Company core driller was directed to create a series of 2-inch-diamater cores 5 inches deep into the piles for integrity (crush) testing of the concrete. Using a Hilti core drill fitted with a 2-inch-diameter diamond bit, the operator took core samples from five piles with low levels of noise and debris. The cores were carefully removed and given to the engineering firm for testing. “It is highly recommended to scan concrete before any core drilling or saw cutting to avoid unwanted hits of structural
reinforcements or embedments. This is why the close collaboration between the GPR analyst and core driller took place, to ensure the safety of everyone involved on this project,” said Stella McAdams, sales and marketing manager for Penhall Technologies.

IACDS 2017 Convention New Format a Success for International Association
I
n an exciting change of program format, the International Association of Concrete Drillers and Sawers (IACDS) held its first annual convention May 18-20 in Vienna, Austria. The event drew a record number of attendees who gathered for an expanded schedule of technical presentations, workshops and networking sessions—welcome additions to the traditional IACDS Annual General Meeting agenda. Almost 60 industry professionals and guests from around the world enjoyed a complete three-day program, which began with a workshop and a meeting of the IACDS Board of Directors. The “Marketing the expertise of the specialists. How to promote the specialized industry” workshop helped participants identify individual customer needs and create a plan to offer the best services and products to each.
The second day consisted of a series of technical presentations. Martin Göedickemeier of Hilti discussed the recently-released IACDS document Guidelines for Anchoring of Sawing and Drilling Equipment, which contains the association’s official recommendations and load considerations during concrete cutting operations. Michael Findeis, a delegate from the German association, Fachverband Betonbohren und -sägen Deutchland e.V., presented the PQ6—a new conical six-times polygon thread for core drill bits—to attendees, designed in conjunction with the German manufacturer association, Verband Deutscher Maschinenund Anlagenbau [read “Goodbye Mallet” from our June 2017 issue for more details]. A prototype of the new PQ6 thread design was displayed in the convention’s exhibit room during the event.

Safety Counts
Opiates and Workers’ Comp: Dangers and Solutions By Tom Garvin
T
he frequent prescribing of strong and addictive pain killers to citizens across the U.S. is a persistent problem that has had drastic consequences for many parties. Opiates are highly addictive and have hindered employees’ abilities to get back to work in a timely manner. That is, if they ever do. Since 1990, the rates of drug-overdose deaths in the U.S. have more than tripled. It is estimated that 40,000 drug overdose deaths occur each year and that number is increasing. Most of these deaths result from physician-prescribed pain killers. In 2014 alone, there were well over 25,000 deaths in the U.S. directly related to prescription drug abuse, as opposed to less than 10,000 in 2001. The Center for Disease Control (CDC) and Prevention states that over half of these
20 | SEPTEMBER.17
deaths are a result of prescription drugs. This number is higher than deaths related to both heroin and cocaine combined. Examples of these frequently prescribed drugs would be Vicodin, OxyContin, Percocet, Duragesic and Fentora, all falling under the category of opiates. The rate at which these drugs are sold to pharmacies is sky-rocketing: it was 4 times larger in 2010 compared to 1999. To understand just how much this is, in just the year 2010, there were enough prescribed pain killers to medicate every adult American 24 hours a day for an entire month. Outside of the already alarming health concerns this poses to the general public, this issue has severely impacted insurance companies’ workers’ compensation policies that are obligated to cover costs of these extremely expensive (and often over
prescribed) drugs. It is estimated that since 1999, sales of prescription painkillers have increased by 300%. The Workers’ Compensation Research Institute (WCRI) has stated that opioids are the most expensive class of medications for work-related injury claims at $450.90 per user, per year. With the increasing amount of prescription drug abuse, it’s easy to see how fast those expenses can add up to scary numbers each year. Insurers have been forced to deal with the consequences of an alarming increase in overprescribing doctors. In fact, according to EHS Today, a website for information on risk management and safety and health management, approximately 55-85% of injured workers in the U.S. are prescribed narcotics for chronic pain.

It’s not just the insurance companies, however, that are suffering the monetary blows. Businesses of every type have lost valuable employees to the dangers of these drugs, and as a result, significant amounts of revenue potential. The time it takes to replace these lost employees with qualified individuals, as well as proper training to get them sufficiently up to speed can hold a business back from staying on the right path towards its production and financial goals. While the owner is getting the business back on its feet again, competitors can gain a significant edge. It is nothing short of a mess, and something needs to be done to reverse this destructive cycle. So what is there to do? A great deal of public attention has been drawn to the dangers of these prescription drugs, as a result of the baffling death rates and the efforts of the CDC. The dire effects on workers’ compensation stakeholders, however, have flown more under the radar. It is a highly complicated problem for an intricate field of insurance, and establishing definitive solutions is extremely difficult. The Insurance Journal Website states that some examples of attempted remedies over the past several years include the tracking of opioid prescriptions through improved databases, harsher punishment for overprescribing doctors, an increase in pain management clinics and stricter company management. These are just a few things that can be implemented by employers today to make sure employees are safe, and employer-to-employee education is the most vital part of this. Brokers are around to make sure employers are not alone in these efforts. Brokers have the resources and capabilities necessary to perform a full and efficient analysis of a business, employees and daily functions, and will be able to provide the necessary recommendations for protecting a business from losing valuable employees to prescription drug abuse. Insurance companies are on the lookout for these types of improvements, as it will have a huge effect on how much risk they are assuming for workers’ comp policies, largely determining the prices they deploy for workers’ comp policies. By educating employees on the dangers of opioids, employers will be able to lower their business’s risk and premium expenses. A huge reason why this problem has had such drastic consequences for insurance companies, is that drug abuse and overdose rates are most rampant among the injured worker population. Back injuries have proven to be a significant driving force in the pattern

of overprescribed opioids. “Further exacerbating the problem is that many work-related injuries occur to the back, for which doctors are increasingly prescribing opioids both short-term and long-term to address pain, despite broad medical recommendations against long-term use of such painkillers in back cases” (Opiod Epidemic, Johnson and Jergler). Dr. Leonard J. Paulozzi is a medical epidemiologist (a physician that specializes in the prevention and control of disease) with CDC’s National Center for Injury Prevention & Control. He has expressed great concern for the worsening epidemic (as the CDC refers to it) of prescription drug abuse, especially with doctors using opioids as long term care for back injuries. “‘There’s an awful lot of back injuries in the workers’ comp population and subsequent surgery related to back problems, and back pain is one of the most common indications now of use of opioids in the United States,’ he said. ‘And it’s being used frequently for back pain and it’s being used long-term for back pain.’” (taken from
22 | SEPTEMBER.17
Opioid Epidemic Plagues Workers’ Comp, an article on the Insurance Journal Website written by Denise Johnson and Don Jergler). Paulozzi also stated that 42% of workers with back injuries were prescribed opioids for long term periods, most of which received them after just their first medical visit, going against the recommendations of using opioids for short term situations only. The opioid-workers’ comp disaster is not a result of a lack of effort to control it. Fortynine states have Prescription Drug Monitoring Program (PDMP) laws. PDMPs are electronic databases, enforced by the state, that are designed to collect data on drugs prescribed within that particular state with the overall goal of combating prescription drug abuse. 44 states have operational programs that are used by physicians to identify patients who are wrongfully seeking prescription painkillers. These tactics, however, have consistently proven to be insufficient in controlling abuse of prescription drugs. Frankly, it’s not even close to enough. Company management in the U.S. needs to start educating its employees more effectively on the dangers of opioids, while
strongly encouraging alternative medicine solutions in cases where strong, addictive pain killers are not absolutely necessary. While it is out of employers’ control of how often physicians will prescribe opioids, it is well within their control to make sure their employees know the dangers, as well as the other effective options that are at their disposal. This simple step in employee education, whether through training programs, webinars, required attendance at educational presentations and other approaches can help everyone: employees will be safer and more aware of the dangers, businesses will not lose their employees to prescription drug abuse, insurance companies will pay less in losses due to these claims and companies will drive down their premium cost by posing less risk. It is far from an absolute, bulletproof solution plan, but it is certainly a huge step in the right direction. Tom Garvin works as an account executive for CSDA member Arthur J.

Diamond Cutter Completes 12 Rounds at Water Treatment Plant
T
he City of Philadelphia’s Water Department had a problem. As part of the department’s clean water tank expansion project, the underground storage basins at one of its treatment plants had to be modified to allow water to flow from one basin to another at a higher volume than before. This required the creation of 12 large 42-inch-diameter openings through a concrete basin wall that tapered out from 28 to 36 inches thick at the marked locations. Core drilling was ruled out due to limited access, so an alternative solution was needed. The Water Department began service in 1801 and supplies water service to approximately 1.7 million people in the City of Philadelphia and a portion of Bucks County. Baxter Water Treatment Plant is situated next to the Delaware River in the northeast of Philadelphia. The plant contains two water basins measuring approximately 500 feet in length and 300 feet wide and it was determined that a series of openings was necessary to create the required rate of flow between them. Philadelphia Water Department employed general contractors A.E. Kelly Group, LLC of Berlin, New Jersey and A.P. Construction, Inc. of Philadelphia for the main expansion project, and these companies began looking for bids to complete the basin openings. CSDA member Concrete Cutting Systems, Inc. of Philadelphia was selected. The concrete sawing and drilling contractor devised a plan to create 12 cylindrical openings spaced 15 feet apart without the use of diamond core bits. “The basins had limited access so we could not fit any large machinery or saws down there,” Dave Nevrotski, owner of Concrete Cutting Systems. “Attempting to get a 42-inch-diameter core drill bit and associated barrels into the basins would have been almost impossible, so we chose to use a circular wire saw setup instead. It was by far the best choice, as the equipment could be taken down into the basins and assembled once down there.”
A dozen circular openings measuring 42 inches in diameter were made.

The concrete basin wall increased in thickness from 28 to 36 inches within the cut area.
Circular wire sawing was the only practical method to cut and remove the concrete.
Access was certainly a factor on this job. The contractor had only a 3-foot-wide door opening to access the basins and there was a 10-foot drop to the floor below. Any tools and equipment had to be rigged to an overhead anchor point and lowered down, so the weight of all items had to be considered too. Operators had ladder access to the basin.
Circular Wire Sawing Mega-Demo at WOC CSDA sponsored a wire sawing demonstration as part of the World of Concrete 2004 Mega Demos. The demonstration was part of the show’s Demolition Derby and featured “Team CSDA,” a group of CSDA contractors and manufacturers who demonstrated

The saw moved through a complete 360-degree rotation to create a cylindrical piece of concrete.
Not only was the wire saw the best choice in terms of accessibility to the work area, but it also provided superior speed, production and finish compared to alternatives like jackhammering. A hydraulic power unit supplied by Husqvarna Construction Products was delivered to the jobsite along with the Tyrolit circular wire saw and the team from Concrete Cutting Systems got to work.
how wire sawing can be used to cut perfect large-scale holes in concrete walls of any size. For this demonstration, a wire saw was used to cut a 6-foot-diameter circle in a wall measuring 8-feet-square by 2-feet-thick. A wire saw consists of a multi-strand cable with diamond segments that is threaded through a series of pulleys. The pulleys are attached to a hydraulic-powered drive wheel that continuously pulls the wire through the concrete. The spinning wire and the constant pulling force cuts a path through the concrete. To cut the large-scale hole using a wire saw, Team CSDA, led by Tim Beckman of Cutting Edge Services Corp., first drilled access holes to attach the wire saw assembly and the saw’s rotating arm. The access holes were drilled on opposite sides of the circle’s circumference, near the 3:00 and 9:00 points on the circle. To perform the actual cutting, operators rotated the wire saw mechanism 180 degrees. When the cutting was complete, operators removed the wire saw mechanism and used a forklift to remove the cut concrete section. The entire process took approximately 12 hours over the course of three days. About 1,500 spectators watched the demonstration from bleachers and many more spectators lined the demonstration area. For more information about wire sawing or the wire sawing demonstration, contact CSDA at 727-577-5004 or tech@csda.org.
Concrete pieces were rigged and pulled from the cut before being broken down and removed from the site.
With all 12 opening locations marked, the first task was to create a series of smaller 4-inch-diameter holes through the center of each one. These holes were used to mount the circular wire saw and allowed operators to pass a 10-foot length of diamond wire from one side of the wall back to the other to make a complete loop. The top feed hole, measuring just 1 inch in diameter, was made at the top of each marked location so that the wire could be fed back and return through the wire saw system. A Shibuya TS252 core drill fitted with 1-inch and 4-inchdiameter bits from DITEQ Corporation was used to core through the basin walls to a depth of around 30 inches. Each center hole took 30 minutes to complete, while the smaller 1-inch holes took 10 minutes. Once the equipment was properly mounted and the diamond wire was looped through the concrete basin wall via the access holes, wire sawing commenced. The saw was built with hydraulic actuated rotation, allowing it to perform a push cut through a full 360-degree rotation and create the circular shape. The diamond wire saw operator monitored progress, adjusting speed and tension as the saw went through its first 180 degrees and the tapered wall increased in thickness from 28 to 36 inches. Further adjustments were made as the saw completed its remaining 180 degrees of rotation and the wall thickness returned to 28 inches. Concrete Cutting Systems completed a 42-inch-diameter circular cut in 1.75 hours, which included setup and takedown time. The cutting contractor then moved the equipment along to the next marked location and repeated this process, completing 12 circular wire saw cuts in total. Concrete cores each measured 137 cubic feet in volume and 27.5 square feet of wire sawing was completed to create them. The 4,400-pound cores were rigged by Concrete Cutting Systems and pulled out from the cut, then removed from the basin by the general contractor’s forklift via the roof hatch opening. All wire sawing work was completed on time and within budget over eight shifts by two operators and helpers.

“The only concern we had going into this job was moving everything safely in and out of the basin of the treatment plant. The rigging system in the roof of the tank had to hold all of our heavy hydraulic equipment. To mitigate any potential failures in the rigging, we triple-anchored with 5,000-pound power bolts,” said Pat Salemno, technician for Concrete Cutting Systems. “Once we were down in the basin, we used wet cutting techniques to eliminate dust and had everyone use the appropriate PPE for the work environment.” “Circular wire sawing the dozen 42-inch-diameter and 36-inch-thick openings at Baxter Water Treatment Plant was an extremely successful and satisfying job for us,” commented Nevrotski. “The total combined years of experience held by our crew gave us confidence that the job could be done well and to the satisfaction of the customer, while our choice of quality concrete sawing tools and equipment gave us the means to execute our plan without any problems,” he added. Coming from the “fighting city” of Philadelphia, the home of movie icon Rocky Balboa, this CSDA member knows how important it is to go the distance—especially when there are 12 tough rounds of wire sawing to complete. Diamond tools provide the speed, efficiency and low levels of noise and debris necessary for cutting contractors to succeed in all types of projects, much like the wire sawing work done at Baxter Water Treatment Plant.

IACDS President’s Insight
T
he International Association of Concrete Drillers and Sawers (IACDS) recently had a very successful 2017 Convention in Vienna. The event gave us a great opportunity to reflect on some of our achievements as an association and to also see where we can continue to improve. Ultimately, the role of any association is to be relevant to its members and provide them with added value. When we looked back on what we had managed to get done over the past couple of years, that certainly shone through. IACDS has released new anchoring and tolerance documents. Both documents required the careful alignment of information and evidence from countries across the world, which has led to them being valuable resources that are considerate of different perspectives. Thanks to the hard work of our national associations and the support of our manufacturer sponsors, both documents are available to view via www.iacds.org and serve as worldwide references for our industry. In terms of communications, we have made a very strong breakthrough online. We have become extremely active, regularly publishing articles and content on our website and social networks. Our Facebook group is growing rapidly, our database of contacts has grown significantly and our newsletter is now distributed to more than 2,000 individuals. To continue this growth, the association must remain focused on why IACDS is relevant to its membership and strive to offer more. What more could we deliver to make the association even more integral to your business? In my view, it all comes down to the expertise that we can offer each other and how the industry can benefit from it. So

Vision of Success Advantages of Scanning Technology Are Clear Metropolitan areas in the U.S. are enjoying an upsurge in concrete construction. The renovation of existing structures and new projects have CSDA cutting and coring contractors responding to a busy marketplace.
D
ue to concerns over equipment, operator safety and damage to structural reinforcement, cutting and coring work requires the avoidance of embedded rebar, post-tensioned cables, utility lines and conduits in concrete. As a result, a growing number of architects, engineers and general contractors are specifying the use of subsurface imaging technology to identify hazards.
The accurate location and mark out of embedded items requires a well-trained technician utilizing multiple technologies, primarily Ground Penetrating Radar (GPR). Experience with concrete reinforcement design, as well as other potential embedments like conduits, is a basic requirement for these technicians. Additionally, their ability to recognize these critical targets from the data collected is the difference between success and failure for each scan they perform. Experience and training are key to the services the technicians provide. CSDA Member GPRS, Inc., based in Toledo, Ohio, offers underground utility location and concrete scanning services across the entire country and the company’s GPR technicians scan hundreds of locations each day.
Objects located under a parking structure in Los Angeles were marked with blue paint (rebar) and red paint (post-tensioned cables).

Parking Permitted The Southern California branch of GPRS was contacted by an engineering firm to scan for post-tensioned cables on the third level of a parking structure in Los Angeles. The purpose of the engineering firm’s work was to repair post-tensioned cables throughout all the levels of the structure, as many of the cables had snapped or no longer sustained the proper amount of tension. The client needed areas marked out prior to chipping through the 6-inch-thick concrete slab.
GPRS technician Alfredo Espinal scanned seven areas measuring 10 feet long by 4 feet wide on one level of the parking structure and marked all findings on the concrete surface with marking paint. All post-tensioned cables identified by the GPR equipment were presented as red paint markings, while rebar was marked with blue paint and steel beams were marked with pink paint. The scanning work took approximately 3 hours using a SIR-3000 unit from CSDA member GSSI, Inc. fitted with a Palm antenna.
Data collected by the GPR unit allowed the technician to show the locations of steel beams below the concrete slab (pink markings).

A GPR technician was able to scan 100 areas marked for anchor plate installations at a parking garage in Grapevine, Texas.
“GPR was a great tool to use for the location of post-tensioned cables, rebar and conduits at the parking structure in L.A. All seven areas were scanned in a short space of time and the results were clearly marked, so the contractor could begin chipping out the concrete without the worry of hitting something,” said Espinal. “The 3000 can also be used to scan for underground utilities prior to digging or excavating, so it is pretty versatile,” he added.
Clinical Results In December 2016, GPRS was requested on site by a general contractor to perform a GPR survey at the Cleveland Clinic-Richard
Imaging Insight from CSDA Many CSDA members have embraced technological advancements in the industry and added GPR to expand their sawing and drilling operations into full service companies. Some have even created separate divisions or businesses. In response this trend, CSDA added a GPR Imaging Contractor membership category in 2013 to represent those who offer GPR as a primary or additional revenue stream. In addition, a CSDA GPR Imaging Committee has been formed with the purpose of promoting the use of imaging technologies, primarily focusing on GPR. Since being formed, the committee has updated CSDA Best Practice CSDA-BP-007 Ground Penetrating Radar for Concrete Scanning and has created a new document CSDA-BP-017 Depiction/Marking of Existing Subsurface Embedments. Both documents are available to download from the CSDA website. In addition, the committee achieved a major goal as CSDA held its inaugural GPR Certification course at World of Concrete 2017 and had 16 participants.

E. Jacobs Health Center in Avon, Ohio. The contractor needed to saw cut a trench to install new plumbing lines and remove existing drains. The contractor needed to know if there were any conduits in the concrete to avoid cutting through them. Micah Stair was the GPRS technician for the job. He located two active electrical/data banks of conduits passing directly through the general contractor’s marked cutting area, employing a SIR-3000 GPR unit and 1,600 megahertz antenna from GSSI, Inc. to cover an approximate 7-foot-long by 2-foot-wide area. The GPR equipment provided Stair with real time scan data for analysis on site, as well as storing the data for documentation.

“The hospital had no drawings showing the conduits. Without scanning the marked area, the contractor would have saw cut through the conduits as they were right at the bottom of the concrete slab,” said Stair. Knowing the depth of the conduits was important for the cutting contractor. Prior to scanning, the equipment was calibrated to the slab so accurate depths would be recorded. The conduits were painted on the surface with depth indications so that the contractor could safely saw cut over or around them without hitting them with the diamond blade.
Drop Anchor! Using GPR technology to scan concrete buildings and structures for anchor installations is a smart choice. Gasten Schoonover, a project manager and GPR technician for GPRS, Inc. based in Texas, was contacted to clear numerous anchor locations on the top deck of a parking garage located in Grapevine. The general contractors on site were tasked with installing anchor plates throughout the
top deck to install permanent barricades and other features. The contractors needed to confirm that post-tensioned cables or other anomalies would not be hit. As other work was being performed in the vicinity, the contactor needed to confirm all locations in a very timely manner and ensure worker safety. “GPRS was able to provide much needed information to move the parking garage project along at an expedited pace. Without the capabilities of radar scanning, the contractors would have had to try to source as-built drawings, which may not have shown any objects installed in the concrete after original construction, or they would have simply had to drill the marked locations and hope for the best,” said Schoonover. Each 2-foot square anchor location was scanned and Schoonover was able to clear 100 plate mounting locations in a single day with his GSSI StructureScan Mini and 1,600 megahertz antenna. He was able to accurately mark out all post-tensioned cables and rebar in the area, and clear each individual plate location for mounting. This ultimately saved time, money and ensured safety on the jobsite.
Scaling Skyscrapers Chicago is nicknamed the windy city, and with good reason! As strong winds blew through the city, Zack Walter, GPRS project manager for the Chicagoland area, was contracted to scan tight spaces atop a 48-story building. Walters was tasked with mapping out rebar so that a general contractor could safely drill anchors for future building plans. A GSSI SIR-4000 GPR unit was used to capture real-time depth views of subsurface hazards such as reinforcement, utilities, conduit and voids. This reduced the likelihood of subsurface obstruction strikes during anchoring installation. “The GPR scanning we conducted on the rooftop ensured worker safety and saved valuable time by targeting the specific areas of concern,” said Walter. “We can provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans. This is all done in a safe, time efficient and non-destructive manner.” REVIEW AND COMMENT ON THIS ARTICLE AT: WWW.CONCRETEOPENINGS.COM

Core Hardness is Critical By Anthony Baratta
W
ith higher horsepower concrete saws and higher speeds at which diamond blades are operated, core hardness has become more critical than ever. Rockwell hardness testing is an empirical measurement of how resistant solid matter is to various kinds of permanent shape change when a compressive force is applied. This test provides useful information that correlates to tensile strength, wear resistance, ductility and other physical characteristics. The behavior of solid materials under force is complex. Therefore, there are different methods of measuring hardness: 1. Scratch hardness 2. Indentation hardness 3. Rebound hardness The concrete sawing and drilling industry utilizes the indentation hardness testing method on the Rockwell C scale.
38 | SEPTEMBER.17
ROCKWELL C INDENTATION TEST PROCEDURE 1. 2. 3. 4. 5. 6.
The sample is placed on a base plate with firm support. A diamond tipped indenter is brought into contact with the sample surface and a preliminary test force is applied and held for a specific dwell time. The height is recorded as a base line. An additional test force on the indenter is applied at a controlled rate until the final test force is achieved and is held for a specific dwell time. The additional test force is removed and returned to the preliminary test force. The depth of the diamond tipped indenter is recorded.
Rockwell hardness values are derived from the difference between the base line and the final depth while under the preliminary test force and additional test force.
Hardness, to core manufactures, means that proper heat treatment has been achieved by rearranging the steel core’s microstructure to the desired mechanical properties. It is optimal to achieve a surface hardness of Rockwell 38Rc for high abrasion resistance and increased wear resistance. However, a lower hardness (34Rc – 36Rc) is desirable since it also increases fatigue resistance and overall core life. The most important indicator of hardness testing is to make sure that the heat treatment has had time to fully transform the steel; since cores that exhibit spotty hardness across the surface are difficult to keep flat and will not hold tension.
To do this, it is important to take measurements across the entire surface of the core. Measurements should be taken and recorded at intervals of 0.25 inch in a straight line. Standard deviation of the data should then be calculated. Standard deviation is a statistical measurement used to quantify the amount of variance or dispersion of data. The standard deviation should not exceed 0.6 plus the tolerance of your hardness tester based on material thickness (See ASTM International Designation E18-15: Standard Test Methods for Rockwell Hardness of Metallic Materials 1, 2). Hardness data within these tolerances indicates full transformation, which is necessary to achieve optimum core quality. To ensure that diamond blades maintain the desired efficiency and lifespan expected from today’s contractors, and that the blades operate effectively with the latest concrete cutting equipment, core hardness is absolutely critical.

The Good, the Bad and the Salty By Erin O’Brien
O
ur food cravings come in many forms, whether it be ice cream, cookies, soda, pizza or in my case, a big bowl of buttery, salty popcorn. We are typically taught these types of cravings are bad for you—too much sugar, fat or salt. I’ve written previously that sugar is bad (Concrete Openings, December 2012) and that fat can be good (Concrete Openings, June 2014), but what about salt? Despite decades of leading health agencies like the American Heart Association and the Department of Health telling us that Americans eat too much salt and it’s making us sick, emerging research suggests that it may not be all that bad for us after all. Here are the facts—in the U.S., Americans consume an average of 3,400 milligrams (mg) of sodium, the predominant mineral present in salt, per day. The 2015-2020 Dietary Guidelines recommend that we intake less than 2,300 mg of sodium per day, while people over the age of 50, African Americans, people with high blood pressure and people with diabetes should consume less than 1,500 mg per day. No matter which group you fall into, we are all ingesting too much sodium, according to these guidelines. One teaspoon of table salt alone contains 2,325 mg of sodium – that’s already more than we are supposed to have in an entire day! Sodium is a vital nutrient used by the body to maintain fluid balance, transmit nerve impulses and contract and relax muscles. It is filtered out of the bloodstream by the kidneys. When there is an excess of sodium in the blood, the kidneys can’t keep up, so the body begins to hold onto water to dilute the sodium. The increased amount of water in the blood leads to a buildup of fluid surrounding the cells and increasing overall blood volume, which makes it harder for your heart to pump blood and places extra pressure on arteries and veins. Over time, this can lead to increased blood pressure, which can raise person’s risk for a heart attack, stroke and developing

cardiovascular disease (CVD). Many studies have linked high-sodium diets with developing high blood pressure and CVD, including a 20% increase risk of death from CVD. High dietary sodium has also been linked to cases of stomach cancer and osteoporosis. But how much salt is too much? According to the studies referenced above, we are all ingesting too much. But for every study that suggests that sodium is bad for you, another suggests the opposite. A major study from 1988, Intersalt, compared blood pressure with sodium intake and found no relationship. Instead, it found the population that consumed the most salt had lower blood pressure than those who consumed the least. The Cochrane Collaboration from 2004 was a review of 11 salt-reduction trials. It found that low-salt diets compared to normal diets reduced systolic blood pressure by 1.1 millimeter of mercury (mmHg) and diastolic blood pressure by 0.6 mmHg (systolic is the top number and diastolic is the bottom number on a blood pressure measurement). This is the equivalent of reducing blood pressure from 120/80 to 119/79 – hardly a significant
reduction. The problem with many of the studies suggesting that a high-sodium diet increases blood pressure and risk for CVD, is that they were not statistically significant – meaning the number of people involved in the study was too small, or there were too many variables. What was learned from these studies is that it is likely everyone responds differently to sodium—some can tolerate higher amounts, while others are more sensitive to it. There are also negative effects from too little sodium. When sodium is reduced drastically, the body releases renin (an enzyme) and aldosterone (a hormone) that both increase blood pressure. One other factor has also been shown to influence blood pressure —potassium ingestion. Potassium can help to relax blood vessels and remove sodium from the bloodstream, therefore decreasing blood pressure. Our bodies need about 4,700 mg of potassium daily, but many people are not getting enough. The average American only intakes about 2,900 mg. The most statistically significant studies have shown that diets high in sodium combined with low amounts of potassium are the most likely to increase a
person’s risk of developing CVD and high blood pressure. Also, those over 50, African Americans and people who have diabetes and high blood pressure are at greater risk to be negatively affected by high-sodium diets. In this author’s opinion, the best course of action to avoid developing CVD and high blood pressure is to consume a moderate amount of sodium coupled with a high intake of potassium. Those with risk factors for high blood pressure should limit their sodium intake. The best way to do this? Fruits and vegetables are high in potassium and low in sodium, and should make up a significant part of anyone’s diet. Increasing your daily water intake will help to dilute sodium in your blood stream and maintain fluid balance. Avoid hidden sources of sodium. Many processed foods like deli meats, canned foods, white bread and rice, pre-seasoned or marinated meats and processed meats like bacon, ham and hot dogs all contain very high amounts of sodium. Read labels and look for ingredients like monosodium glutamate (MSG), baking soda (sodium bicarbonate), baking powder, disodium phosphate, sodium alginate, sodium citrate and sodium nitrate, which are all additives that will drastically increase the sodium in any food. Use flavor substitutes instead of table salt like fresh and dried herbs, spices, garlic, onions and citrus zest and juice. These ingredients will add a lot of flavor to your meal without adding a lot of calories or sodium. Switch from standard table salt to sea salt—the salty flavor is more concentrated so you can use less. Finally, cut back gradually on your salt intake—your salty cravings are acquired, and you may eventually not miss it. Most of the sodium in our diets come from processed foods—75% on average. About 15% comes from food preparation and table salt, while only 10% of dietary sodium is naturally contained in food. Cutting down on processed foods will significantly decrease your dietary sodium intake if needed. I like to think of quality over quantity—I love the salty taste in food, so I try to use high quality, flavored sea salt and drink water all day long so I don’t have to cut out or reduce how much salt I eat. I also have drastically reduced the amount of processed food I eat. Processed foods have all kinds of other terrible things in them like preservatives, chemicals and hormones, so they are best to avoid as much as possible anyway. One final note—a recent study concluded that consuming less than 3,000 mg of sodium

Something’s Phishy: How to Detect Phishing Attempts By Wendy Zamora Dear you, It appears you need to update your information. Click here to tell us all your secrets. No really, it’s totally safe. We’re not going to steal your identity, we swear.
If only phishing attempts were that obvious. Instead, these days it’s hard to tell a phish apart from a foul, if you catch my drift. Modern-day phishing campaigns use stealthy techniques to target folks online and trick them into believing their messages are legit. Yet for all its sophistication, phishing relies on one of the basest of human foibles: trust. Detecting a phish, in its various forms, then requires you to hone a healthy level of skepticism when receiving any kind of digital communication, be it email, text or even social media message. In order to understand how we got here, let’s go back to the first instance of phishing. THE NIGERIAN PRINCE AND EARLY PHISHING Back in the early days of the Internet, you could marvel at your “You’ve Got Mail” message and freely open any email that came your way. You’d get one email a day, tops, from your new best friend you met in the “grunge 4EVA” chat room. There was no such thing as junk email. The only promotions you received were CD copies of AOL in the snail mail. It didn’t cross your mind that going online could bring about danger. Then came the Nigerian prince. Unfortunately, where innovation and progress lead, corruption and crime will inevitably follow. One of the nation’s longestrunning scams, the Nigerian prince phish came from a person claiming to be a government official or member of a royal family who needed help transferring millions of dollars out of Nigeria. The email was marked as “urgent” or “private,” and its sender asked the recipient to provide a bank account number for safekeeping the funds. Gone were the innocent days of trusting your inbox.
42 | SEPTEMBER.17
Over the years, the Nigerian prince scam has fooled millions, raking in hundreds of billions of dollars. Why has this scam been so successful? Simple. It uses a timehonored criminal technique—the ole bait and switch—to fool folks into believing that they are being contacted by a legitimate organization with a legitimate concern. Threat actors use this social engineering method to trick unwilling participants into clicking on malicious links and handing over personal information. The end goal, as with most cybercrime, is financial gain. Phishing attacks aim to collect personal data—including login credentials, credit card numbers, social security numbers, and bank account numbers—for fraudulent purposes. The attack is most commonly delivered as an email communication that spoofs a known enterprise, such as a bank or online shopping site, but it can also appear to come from an individual of authority or of personal acquaintance. These emails always contain
a link that sends users to a decent facsimile of a valid website where credentials will be collected and sent to the attacker, instead of the supposedly trusted source. From there, the attacker can exploit credentials to commit crimes such as identity theft, draining bank accounts or selling personal information on the black market. “Truth be told, phishing is the simplest kind of cyberattack and, at the same time, the most dangerous and effective,” says Adam Kujawa, Director of Malware Intelligence. “That is because it attacks the most vulnerable and powerful computer on the planet: the human mind.” THE EVOLUTION OF PHISHING While the Nigerian prince attack vector remains in use today, most savvy Internet users can now spot this scam a mile away (hence the multitude of memes that have popped up over the years). The campaign has lost its edge and fooled way fewer users.
Plus, email technology has progressed so that spam filters readily pick up on this phish and block it. And this is why cybercriminals have had to advance their tactics. “Phishers had no other choice but to evolve and improve on where they fell short,” says Jovi Umawing, Malware Intelligence Analyst at Malwarebytes. “Nowadays, most sophisticated modern-day phishing emails are so polished and well-designed that one cannot easily differentiate them from legitimate ones.” Case in point: Recent phishing campaigns have had great success impersonating big-name companies and fooling big-name recipients. In May 2017, a phishing email targeted one million Gmail users by purporting to be from a contact sharing Google Docs. In Minnesota alone, state employees were scammed out of $90,000 due to the Google Docs fiasco. Hillary Clinton’s campaign manager for the 2016 presidential election, John Podesta, famously had his Gmail hacked and subsequently leaked after falling for the oldest trick in the book—a phishing attack claiming that his email password had been compromised (so click here to change it). So how can we learn from these lessons? Let’s start by identifying the different types of phishing in use today. TYPES OF PHISHING The most basic and commonly seen type of attack, of course, is the phishing email. Phishing emails are sent to a group of users who are unique enough to be used as bait but broad enough to ensnare a large number of people. The point is to cast as large a net as possible. In contrast, other forms of attack are much more targeted. Spear phishing, as might be gathered from its title, usually targets a specific person or organization. Since these types of attacks are so pointed, phishers scour the Internet for available information about their target in order to craft a believable email to extort information (if not money) from victims. Whaling is a form of spear phishing directed at executives or other high-profile targets within a business, government or other organization, such as a CEO, senator or someone who has access to financial assets. CFO fraud is an example of whaling. Smishing, short for SMS phishing, is carried out via SMS text messaging on mobile devices. A similar technique, vishing,
W WW. C O N C RE TE OPE N IN GS.COM
is voice phishing conducted over the phone. Pharming, also known as DNS-based phishing, is a type of phishing that involves the modification or tampering of a system’s host files or domain name system to redirect requests for URLs to a fake site. As a result, users have no idea that the website they are entering their personal details into is fake. Content-injection phishing is when phishers insert malicious code or misleading content into legitimate websites that instructs users to enter their credentials or personal information. This type of phishing is a form of content spoofing. Man-in-the-middle phishing happens when phishers position themselves between people and the websites they use, such as a social networking sites or online banks, to extract information as it’s being entered. This type of phishing is more difficult to detect because attackers continue to pass on users’ information (after collecting it) so as not to disrupt any transactions. And finally, search engine phishing starts off when phishers create malicious websites with attractive offers and search engines index them. People then stumble upon such sites doing their own online searches and, thinking the sites are legit, unknowingly give up their personal information. There truly are a lot of phish in the sea. So, if your head isn’t completely swimming in fish puns, it’s time to talk about how to train your eye and your gut to sniff out the various forms of phishing attacks. I asked Labs researchers to tell me their top indications that an email, text, or other form of communication is a phish and compiled a list of their, and my, recommendations. SOMETHING’S PHISHY IF: •
•
•
•
The email, text or voicemail is requesting that you update/fill in personal information. This is especially dubious if it’s coming from a bank or the IRS. Treat any communication asking for your credentials with extra caution. The URL shown on the email and the URL that displays when you hover over the link are different from one another. The “From” address is an imitation of a legitimate address, especially from a business. The formatting and design are different from what you usually receive from an organization. Maybe the logo looks pixelated or the buttons are different
•
•
•
•
colors. Or possibly there are weird paragraph breaks or extra spaces between words. If the email appears sloppy, start making the squinty “this looks suspect” face. The content is badly written. Sure, there are plenty of wannabe writers working for legitimate organizations, but this email might seem particularly amateur. Are there obvious grammar errors? Is there awkward sentence structure, like perhaps it was written by a computer program or someone whose second language is English? Take a closer look. Speaking of content, a phishing email almost always sounds desperate. “Whether they’re claiming that your account will be closed, an urgent request is needed or your account has been compromised, think twice before doubleclicking that link or downloading that attachment,” says Umawing. The email contains attachments from unknown sources that you were not expecting. Don’t open them, plain and simple. They might contain malware that could infect your system. The website is not secure. If you do go ahead and click on the link of an email to fill out personal information, be sure you see the “https” abbreviation as well as the lock symbol at the beginning of the URL. If not, that means any data you submit is vulnerable to cybercriminals (If the link is malicious, Malwarebytes will block the site).
If you suspect or can verify that you’ve been phished, it’s best to report the attempt directly to the person or organization being spoofed. You can also contact the Federal Trade Commission (FTC) to lodge a complaint. Once completed, delete the email, then empty your trash (the same goes for texts). Now the next time someone attempts to scam you with fraudulent emails, you won’t have to wonder if the message is for real. You’ll scope out a phish hook, line and sinker.

Bosch Bulldog Xtreme SDS-plus® rotary hammer bits have been optimized for use with cordless power tools based on a two-flute design for speed in dust removal with less potential for binding. The Bulldog Xtreme line has full-head carbide for bits up to 0.625 inch. Bits beyond this diameter feature a four-cutter design. Full-head carbide bits feature the Velocity flute design: four flutes that transition to two larger flutes for increased dust removal capacity and a cleaner hole. The bits deliver performance in reinforced concrete or harsh aggregate, plus lightweight and normal weight concrete. Bosch utilizes a proprietary diffusionbonding technology, a high-heat, high-pressure solidstate welding process that produces a strong steel/ carbide bond. The centric conical tip guides the bit and results in rounder holes, important when setting anchors or fasteners. A wear mark alerts the user when the bit has worn to a level where it is no longer precise. Bit sizes for the full range extend from 0.188 to 1.125 inches in diameter.

Hilti Introduces Two New 36-Volt Cordless Tools
Ed Dempsey, 1937-2017
Hilti has expanded its 36-volt cordless tool line with the introduction of the cordless rotary hammer TE 6-A36AVR (pictured) and the cordless angle grinder AG 600-A36. These new cordless tools perform as well as their respective corded versions without the hassle of a cord and external power source. Featuring Hilti Active Vibration Reduction (AVR) technology, the Hilti cordless rotary hammer TE 6-A36-AVR has two battery options, the Hilti B36/5.2 CPC Li-Ion industry class battery for the most work-per-charge performance and the B36/2.6 Li-Ion compact class battery for operators who need to reduce the tool’s operating weight. The tool’s ergonomic design has a D-grip for comfort over long periods of time and built-in AVR. It includes a chiseling feature for light-duty corrective chipping and can be converted to virtually dust-free operation by adding the optional TE 6-A dust removal system (DRS). It delivers 1.5 foot-pounds of single impact energy and a 1,040-rpm gear speed for drilling and hammering in concrete or masonry. Using an optional quick-release chuck, this cordless rotary hammer can also be used on steel, wood and plastic.
Industry professional Edward J. Dempsey passed away July 1, 2017 in Huntington Beach, California. He was 80 years old. Ed was born in Chicago, Illinois and moved with his family to Elsinore, California in 1945. He was a graduate of dual degrees at Occidental College and Cal Tech. In 1961, Ed became one of the pioneers in the concrete cutting/ Ed Dempsey coring industry when he founded Concrete Coring Company. He developed cutting edge techniques and introduced the use of 400-hertz power for the equipment he designed. He held multiple patents in this field. Ed’s love of 400-hertz electric motors and speed led him to build and race an electric streamliner known as “White Lightning”. His company Dempsey’s World Record Associates (DWRA) held the FIA world speed record set in 1999 at 245.523 mph for eleven years. Ed was also a pilot, skier, fisherman, yachtsman and long-time resident of Huntington Harbor. He recently celebrated his 80th birthday on June 15th with family and friends. Ed is survived by his wife, Millie Dempsey of Fountain Valley, one son, John Curtis Dempsey of Las Vegas and two brothers – George and Richard (Kathy) Dempsey of Las Vegas, Stepsons, Gus (Bianca) Fowlie and Dan Fowlie, two stepchildren Sean Fowlie and Daniel Fowlie Jr. He was preceded in death by his son, Michael Dempsey and step-daughter, Michelle Fowlie.

Janine Lessor, 1934-2017 Janine Lessor, wife of CSDA Past President David Lessor for more than 60 years, died June 21, 2017 from complications with diabetes. Janine passed at home with Dave by her side. Janine was born January 9, 1934 and married Dave on September 8, 1956. The couple have a son, Steve (Deana), a daughter, Lisa (Jeff) Czyson and three granddaughters— Hayley, Meaghan and Lindsay. Janine loved traveling to CSDA functions around the world, including events in Hawaii, Toronto, London and Japan. She really enjoyed the friendships she made through CSDA and always looked Janine Lessor forward to the meetings. It was a real pleasure for Dave and Janine to host a get-together during one of the association’s meetings in Minneapolis and they had a great time visiting some of the city’s attractions. She is missed by Dave, her family, friends within CSDA and all who knew her.
Aqua Cutter 710V Hydrodemolition Robot Released
Geophysical Survey Systems, Inc., a leading manufacturer of ground penetrating radar (GPR) equipment, is pleased to announce the promotion of David Cist to the position of Vice President of Research & Development. Since 1996, Dr. Cist has helped GSSI to develop several key products, including an arrayed utility mapper and a series of search and rescue tools. Promoted from “chief geek” in 2015, and more recently to interim Director of Research & Development, Dr. Cist continues to provide leadership within GSSI to drive innovation and product strategy. A long-time GSSI employee, Dr. Cist recently celebrated his 21st year with the organization. After graduating from Princeton University with a BSE degree in Electrical David Cist Engineering and Computer Science, Dr. Cist worked in market research and then in R&D for Siemens Medical in Germany. Dr. Cist completed his education at Massachusetts Institute of Technology, with a Master’s degree in Radiology Science (Simulated Annealing image reconstruction), and finally a PhD in Geophysics (3D Migration of GPR data). GSSI is confident Dr. Cist’s new position will foster innovative solutions to further extend GSSI’s role in the GPR industry.
Aquajet Systems AB has released the Aqua Cutter 710V hydrodemolition robot. The 710V comes equipped with ceramic nozzles that can last up to 79% longer than standard steel versions. The 5,070-pound Aqua Cutter 710V uses 14,500- to 40,000psi water jets to remove as much as 35 cubic feet per hour of concrete. Contractors adjust the robot’s stroke to control the depth of cut and vary the pressure of the water jet. Unlike traditional pneumatic tools or milling machines, rebar is cleaned and descaled during the cutting process. Aquajet constructs the 710V’s steel mast in sections—an innovative design that gives the operator freedom to raise the front power head as high as 23 feet, 10 feet higher than the Aqua Cutter 410V—without additional support. The 710V features an 18-kW diesel engine and contractors can add an Aquajet Hybrid Kit, which attaches to a diesel-powered Aqua Cutter robot for electric operation in applications where diesel engines aren’t allowed. The kit uses an intelligent system to automatically disengage the onboard diesel engine.

TESTIMONIAL
TRAINING
Concrete Scanning and Imaging, Inc. is a Women’s Business Enterprise specializing in Ground Penetrating Radar (GPR), concrete scanning and private utility locating company in the New York metropolitan area and a proud member of CSDA. The company has built a reputation in the industry based on our dedication, reliability and our emphasis on jobsite safety, all common values we share with CSDA. Being a member of CSDA has helped in cultivating Concrete Scanning and Imaging’s culture and company growth. From my first Jillian Russo Concrete Scanning and Imaging, Inc. interaction, I knew CSDA was unlike any other Waldwick, New Jersey trade organization. I quickly came to realize that it is at the hands of its leaders and members, a group of like-minded industry professionals whose main goal is to create a safe and sustainable industry and promote it to the specifier community. When founding Concrete Scanning and Imaging, Inc., it was the CSDA owners, estimators and operators I had met at trade shows and organization events who helped in my mentorship. Furthermore, the guidance and support from CSDA volunteers and classroom instructors has provided me, and other new members of the association, with indispensable knowledge and support through GPR Certification, estimator training and networking provided by the CSDA Next Generation Committee, to name a few.
OVER 4,000 INDUSTRY PROFESSIONALS HAVE GRADUATED FROM MORE THAN 20 CLASSROOM, HANDS-ON AND ONLINE CSDA TRAINING AND CERTIFICATION PROGRAMS FOCUSED ON CUTTING DISCIPLINES, ESTIMATING, POLISHING AND SAFETY. ONLINE TRAINING AT WWW.CSDATRAINING.COM OFFERS A COST-EFFECTIVE ALTERNATIVE TO THOSE NOT ABLE TO AFFORD THE TIME OR THE MONEY TO SEND OPERATORS TO CLASSES.
CSDA has allowed me to meet fellow industry members from all over the world who showed transparency and support, giving me the knowledge and mentorship needed to help grow Concrete Scanning and Imaging, Inc. and the GPR industry.

Director’s Dialogue
2018 Convention in Maui
PATRICK O’BRIEN Executive Director
I
n 1997, CSDA made a bold move to celebrate its 25th Anniversary with a convention in Hawaii. At the time, we thought that this visit to Hawaii would be a one-time event. However, the attendance at that 1997 convention was over 300 people, double the attendance of many mainland sites. A year or two later, members began asking when CSDA would be returning to Hawaii! CSDA did return in 2003, and then again in 2007 and 2012 with record attendance each time. You can’t argue with success, so in 2018 CSDA returns to its favorite destination on the island of Maui. The location on Maui is different this time. The three previous visits were to the Kaanapali Beach area on the west coast, but next year CSDA will be on the southern coast at the fabulous Waldorf Astoria Grand Wailea. The hotel is situated on 40 acres fronting spectacular Wailea Beach, a beautiful area with calm waters. If you compare CSDA’s negotiated room rates with the rates the hotel is currently offering, you will discover that the association’s Convention Committee did an excellent job to make this awardwinning Waldorf Astoria property very affordable for members! Because there are so many exciting activities to do in Maui, CSDA will be offering full-day activities prior and post-convention, as well as during the event. See the sunrise from 10,000 feet on top of Mt. Haleakala, snorkel in Molokini Crater, drive the Road to Hana and sail with humpback whales.
60 | SEPTEMBER.17
Maui has much to offer, but the secret to a successful convention is the combination of business and recreation. The CSDA Convention Committee has worked hard to put together the best offering of business and optional activities to again attract a record crowd to Maui. Many attendees extend their stays to include a vacation in addition to the networking and business-related sessions attended during the convention. While Maui offers many things to do, convention attendees will benefit from the many technical, educational and business sessions offered. The biggest benefit of getting together with other CSDA members, however, is networking. The personal relationships developed by members at the annual conventions have fostered an exchange of information and personal friendships that have lasted a lifetime. So maybe the reason for excellent attendance is a convergence of a beautiful location, business and networking. Join your fellow members in Maui for the March 8-10, 2018 convention. Or come early and participate in the March 6-7 Board and committee meetings. And those all-day adventures will take place early on March 5th or late on March 11th.

The Hilti X-Scan PS 1000 can detect reinforcing bars, pre- and post-tensioning cables, metal pipes, plastic pipes, electric cables and glass-fiber cables in next to no time — even over large concrete areas. Scan results are presented on the X-Scan display for immediate analysis or can be transferred to the Tablet PSA 200 for further evaluation. Thanks to its ease of operation, on-site handling and the easily interpretable 3D images of concealed objects it produces, the Hilti X-Scan PS 1000 takes non-destructive structural inspection into a new era.

COMPLETING YOUR WALL SAWING SYSTEM WORK SMARTER AND SAFER WITH THE WSC 40. The WSC 40 is a unique remote-controlled chainsaw attachment for wall saws designed to cut precise corners as well as flush cut. The attachment converts your WS 482 HF or WS 440 HF wall saw from blade to clain sawing by easily attaching to the spindle and fits into the kerf without re-positioning the rail. The WSC 40 accurately saws without overcutting and enables the operator to cut in a safer, more precise and ergonomic way. We have also developed the PRO45 diamond chain to cut quickly through reinforced concrete. Demonstrations available nationwide.
