t is now March. Another World of Concrete is complete, with a strong showing by the terrific vendors who are strong supporters of CSDA. Thanks for all you do to support the industry! Now spring is just around the corner, and so is CSDA’s Annual Convention—an event that should not be missed! If you haven’t made plans to attend, there is still time to register so you can take advantage of the outstanding education offerings, network with colleagues, meet new people that face business challenges similar to yours, and of course, the Tech Fair that provides you intimate access to suppliers to discuss challenges and issues as well as new products that can help you with your projects. All of this while enjoying the beautiful La Costa Resort and Spa in Carlsbad, CA! The Convention runs from April 2–4, with the spring committee meetings and Board meeting taking place just prior to the convention on March 31 and April 1. If you haven’t attended previously, I’ll refer to a phrase used in my column from our last issue that comes from Russell Wilson of the Seattle Seahawks, “Why not you?”

My last column addressed setting goals for the year, both personal and professional. It’s a subject that leads to providing guidance for how

we go about our work throughout the year. In that vein, CSDA also sets goals that help chart our course for the year, and we will be doing that during the committee meetings mentioned above. We will continue to focus on topics such as safety and training, but would also love to hear from you concerning what you need from CSDA. There’s no secret that we are all dealing with the challenge of attracting new workers in an environment where it seems that everyone wants to write code and develop new games. CSDA is working to address the training of new operators and will soon release a new online version of “Cutting Edge” to introduce concrete sawing and drilling to new staff that you hire. It will also serve as a pre-requisite to the 101 and 201 classes that are scheduled for the fall. By working together, and with intention and attention, we can grow the ranks of operators to ensure that we have the people we need to serve our customers. Join us in tackling this issue by becoming involved with CSDA. A bit of light work by many can help make this a productive undertaking. What do you have to lose?

Cheers.

Built to Last Texas Contractor Revitalizes Historic Fort Worth Landmark

O

ne of the most recognizable landmarks in Fort Worth, Texas is One Montgomery Plaza. When it was built in 1928, the eight-floor, Mission-Revival style building served as a regional retail and mail order warehouse for Montgomery Ward. The building originally allowed for trains to come in between its two towers to be unloaded and was the largest building in Texas. It was quickly recognized as an architectural icon.

6 | MARCH.20

The spa area of the rooftop pool deck after demo.

Montgomery Ward’s building was constructed in a bygone era with large, sweeping windows, 12-inch thick concrete walls and a certain majesty that’s hard, if not impossible, to capture today. The construction featured reinforced concrete with 20-foot centered columns throughout. In some areas, two- to three-story wing additions were built, each designed to have five more floors added at a future date.

The structure was built to last, surviving the Fort Worth flood in 1949 that reached its second floor and the Fort Worth tornado in 2000. Montgomery Ward rolled up their operations in 2001, and in 2004, the building was sold and eventually converted into luxury condos and retail space, where the building’s original art deco style was preserved.

On the 3rd floor roof of One Montgomery Plaza is a 66-foot pool and adjoining spa. In 2018, the waterproofing membrane between the structural slab and the topping slab failed. Water damage caused a 20 percent failure in the structural steel below the slab and in the planter anchors. General Contractor (GC) J. Reynolds, Inc. was hired to remove the topping slab and

waterproofing, repair the damaged steel and concrete structures, install new waterproofing and a new topping slab and restore the pool and terrace. J. Reynolds hired CSDA member Magnum Sawing and Coring of Irving, Texas to saw cut and remove the topping slab and demo the spa area next to the pool down to its steel structure.

Magnum faced four significant limitations on this job: weather, tenants, power and weight.

The weather in January and February in Fort Worth can be unpleasant and unpredictable, and this year was no exception.

Magnum battled ice and freezing rain and had seven weatherrelated shutdowns during the 39-day job.

The condos and retail space were occupied, and the owners wanted to limit as much as possible any inconvenience to the tenants. Magnum only had access to one stairwell to get tools

and personnel to the 3rd floor. This necessitated the use of a crane to hoist heavy equipment to the roof and remove the pieces of concrete and debris. The GC hired a shoring contractor to build a platform so debris could be removed from the jobsite to street level.

Another issue was there wasn’t enough onsite power to run Magnum’s equipment, so Magnum brought their own 6500 watt portable generators to power their multiple saws, core drills, jackhammers and custom built Wet Vacs.

Since they were working on a roof, there was a strict weight limit. The typical heavy equipment couldn’t be used. A Bobcat S-70 loader was light enough to place on the roof and for the crane to hoist it up and down.

After drilling twelve 7” diameter test cores with Diamond Products Weka DK 22 Core Bores, Magnum determined that

sawing was the best way to remove the slab. Saw cutting would create less debris, dust and vibration. They also had to consider the 100-year-old structures below the slab, which ruled out the excessive vibrations that robotic hammering would create.

The first step was to hand demo the spa. Stihl 16” gas hand saws, Bosch Turbo Brute electric jackhammers and wheelbarrows were used to break up the concrete into pieces and move it off the roof. In some areas around the spa, the concrete was overpoured to 36” thick.

The next step was saw cutting the topping slab into sections.

The slab was cut with a walk-behind Diamond Products Core Cut 60 hp diesel concrete saw with Husqvarna F297C slab saw blades. Four men hauled pieces in two-wheel dollies and a Bobcat S-70 Skid Steer to a loading platform. There, the pieces were placed in a loading hopper on a high reach SkyTrak 55-foot

shooting boom lift. The slab pieces and debris were stockpiled in the laydown yard and later hauled off for recycling.

Next on the hit list were two 12-inch thick structural stairs leading to the pool. These also had to be demoed with hand saws and jackhammers.

Finally, a 40’ x 4’ ramp had to be demolished, but the walls on each side of the ramp could not be damaged. Magnum made a few longitudinal cuts with the Core Cut slab saw, hand sawed the crosscuts, then jackhammered the ramp slab.

Obviously, working with heavy equipment on an open third floor roof poses its hazards. To ensure safety, Magnum had a supervisor on the job full time and a watchman on the platform whenever the rail was removed. Safety meetings were held with the GC weekly. Meetings with the crew were held regularly to prevent back and hand injuries, discuss eye and hearing

protection, and to remind them about the importance of good housekeeping on the jobsite. Surprise safety inspections also occurred to keep everyone on their toes. Only certified employees operated the Skid Steer and the SkyTrak.

When the job was finished after 39 days on site, Magnum had drilled twelve 7-inch diameter test cores, slab sawed and removed (by hand) 13,250 square feet of 6-7” concrete topping slab with reinforcing steel bars and cut 22,750 linear feet of 6-7” slabs. Magnum finished the job early, even with seven days of delays due to bad weather.

Danny Spencer at Magnum remarked, “The Magnum crew worked as a team to get a big job done fast. Having a great client to work for with qualified supervision and project management was a big plus. We were selected for the job because we worked with J. Reynolds before and they knew we could get big projects done on extreme deadlines with no room for mistakes.”

CSDA contractors are often called upon to tackle complex and sensitive job quickly, efficiently and safely. Magnum again proves why diamond cutting techniques and CSDA contractors are the best choice when needing the job completed successfully with precision and accuracy.

Repurposed Bridge Finds New Life in British Columbia Decommissioned Hood Canal Bridge Now Repurposed All Over the World

S

ewell’s Marina in British Columbia, Canada sits on picturesque Horseshoe Bay, at the entrance to Howe Sound.

The marina hosts three million visitors a year to their ocean playground and is a popular spot for boaters and travelers. Sewell’s Marina offers moorage, a fuel dock, launch ramp, boat rentals and a tourist information center.

12 | MARCH.20

In February 2019, a severe winter storm caused a rupture in the marina’s protective breakwater, a large barge that was permanently moored to the sea floor.

Replacing a breakwater is no easy task. Fortunately, the owners of Sewell’s Marina discovered that parts of Washington State’s decommissioned Hood Canal floating bridge were stored nearby on the Fraser River in Vancouver. Parts of the former bridge had been repurposed all over the world – one section was

towed to the north coast of Australia to be used as ship berthing docks; two sections now support the cruise terminal in Sitka, Alaska and one section was towed to Port Alberni, B.C. for use as a breakwater and pier. The last remaining section of the well-preserved floating concrete pontoon stored on the nearby Fraser River could be modified to create a new breakwater.

One major problem—the 1,087foot pontoon was too big. The new breakwater had to be 661 feet long.

In 2009, CSDA member Cutting Edge Services of Batavia, OH, did the initial wire sawing of the Hood Canal bridge over a period of 45 days. In 2013, some of those parts were wire sawed by CSDA member Canadian Cutting and Coring of Vancouver, B.C. for repurposing. Because of their previous work on the Hood Canal bridge sections, Sewell’s Marina called on Canadian Cutting and Coring (CCC) to right-size the pontoon for use as a breakwater in Horseshoe Bay. CCC determined that the only way to modify the pontoon was with two vertical cuts. The cutting would be done at the storage location on the Fraser River and when complete, the pontoon would be towed to its new home at Sewell’s Marina.

At one end of the pontoon stood what remained of a concrete and steel control tower which had been used

for opening and closing the bridge. The control tower had to be removed before the vertical cuts could be made. But if a 120-ton-plus concrete structure was suddenly removed from one side of the pontoon, the entire pontoon would capsize or at best become very unstable.

Additionally, removing hundreds of square feet from the length of the pontoon would also make it unstable. Re-ballasting to compensate for the buoyancy would have to be undertaken first.

Re-ballasting was accomplished with careful calculations. Then, water was pumped in or out of the isolated cells in

Hilti wire saws were used to cut the concrete into 529 square foot sections.

the pontoon. CCC emptied the cells on the opposite side from the tower before cutting began.

The aged control tower was 44 feet high with a base footprint of 15’ by 15’ and a steel structure at the top. The peak of the control tower was first to go - CCC used cutting torches to cut the structural steel roof members. Then, the steel was lifted in one piece by a 600-ton crane. CCC then went to work on what remained of the control tower with a Hilti TS-20 wall saw, cutting the concrete structure into two sections weighing 40 tons and 80 tons. The top half was lifted by crane onto the opposite pontoon.

Then the bottom half of the control tower was sawn off at the base and lifted onto the opposite pontoon. Later, the remnants of the control tower were transported by barge for demolition by a salvage company.

Once the tower was gone, pre-tensioning cables had to be cut in the pontoon without damaging the internal walls. CCC placed wood cribbing behind the ends of the post tensioning cables and in front of the internal walls. When the cable was released, the wood absorbed the energy of the impact, protecting the walls from damage.

Next, the sections of the pontoon which connected the two lengths had to be cut. The only catch was that these sections were submerged 17 feet underwater. Further complicating cutting was the amount of slurry that would be created, which could harm marine life. To minimize the marine impact, a slurry containment jacket was designed in-house and built by a client. The slurry jacket was basically a stainless steel channel strapped around the bottom and sides of the pontoon. Vacuums were used to remove the slurry from the channel and then emptied into a Golz slurry recycling system onsite.

At last ready to make the vertical cuts, CCC drilled six core holes with Hilti core drills and six Diamond Products Weka core drills for the diamond wire

runs. Then three vertical cuts were made in each section of the pontoon with a Hilti WS-15 wire saw. Each section measured 529 square feet. Core bits were custom manufactured by Cyclone Diamond Products of Burnaby, B.C., and diamond wire was supplied by Hilti and Cyclone.

With the vertical cuts complete and the pontoon rightsized, this former piece of the Hood Canal bridge was ready to be towed to its new home in Horseshoe Bay. John Van Dyk of Canadian Cutting and Coring said, “This is an excellent example of using cutting technology to re-purpose a structure. We were able to quickly replace the storm-damaged breakwater with a much more robust concrete structure, offering improved marine protection for Sewell’s Marina and the entire small boat basin at Horseshoe Bay.” CSDA contractors have a long, successful history of collaborating on complex and large projects. The relationship between Cutting Edge Services and CCC, and then the ensuing relationship between CCC and the marina owners gave the confidence to all parties involved that CCC would be able to complete this project without any issues. Concrete cutting techniques continue to help re-purpose structures around the world.

Bit by Bit - Selecting the Right Bit in Concrete Demolition Applications to Maximize Efficiency

By August Scalici and Jeff Keeling

S

electing the right tool for the job at hand is key when it comes to minimizing effort and maximizing efficiency. In concrete demolition, this begins with the carrier. Contractors must determine which machine provides the powerto-weight ratio needed to get the job done.

From heavy-hitting multi-ton excavators to handheld pneumatic devices, there are several options available. However, many contractors are finding success with remote-controlled demolition machines. This equipment offers industry-leading power-to-weight ratios with the versatility and efficiency to master several applications — including indoor and top-down demolition in congested urban areas.

The carrier might be a key factor in the efficiency equation, but when it’s time to start the actual demolition everything rests on the tip of the machine. A moil point and a blunt tool will both break concrete, but which one

18 | MARCH.20

provides the ideal result with minimal effort?

Choosing the right bit for the task at hand can increase efficiency, while the wrong choice can slow down productivity or leave behind unsatisfactory results. A contractor who knows the difference can end up with a huge advantage in an increasingly competitive field.

Depending on their service offerings, a toolbox full of bits isn’t necessary for every concrete demolition contractor. Here are some tips to help select the right tools to keep on hand to maximize efficiency with remotecontrolled demolition machines.

Moil Point The moil point tool is the most common bit found on jobsites. It’s shaped like a pencil and is ideal for breaking hard concrete reinforced with rebar. This design focuses the entire force of the hammer and carrier in a 1/4-inch point which limits vibrations, making it the ideal

option for indoor applications and other situations where vibrations are unacceptable.

The moil point is the everyday workhorse of concrete demolition, providing highefficiency and reliability, and, for that reason, it’s become the standard bit for most new breakers.

The moil point offers good control, allowing operators to demolish around rebar with precision and efficiency for applications such as walls, footings, floor foundations or machine bases. However, it does not provide the level of precision necessary for fine detail work. There is also a risk the coneshaped head will get stuck when breaking concrete, often the result of material failing to expand fast enough and trapping dust close to the tool, lodging it in place. Paying special attention to the running time of the hammer can help avoid this, though. If the hammer runs for more than 20 seconds in the

same spot without noticeable results, the tool should be removed from the hole immediately, otherwise there is a good chance the bit will become stuck.

There are several variations of the moil point that can further increase overall efficiency in certain situations. A pyramidal moil point, also known as a “nail head”, for example, provides minor torsion and a wedge effect in four directions, making it more efficient as a dividing tool than a conical moil. This is especially true in tools with a larger diameter.

The slight variation in shape also keeps the “nail head” from getting stuck as much as its conical counterpart. However, a lack of knowledge often leaves operators stuck with the traditional cone-shaped moil rather than a tool more appropriate for the job at hand.

Chisel A chisel tool looks similar to a flat-head screwdriver and is available in standard and wide widths. The chisel provides strong torsion and good penetration, resulting in the best splitting action. It is ideal for trimming applications including floors, walls and foundations, as well as demolishing reinforced columns, supports and blocks. For example, the chisel can be used to clean up between rebar on the edge of a slab to ensure an ideal bonding surface for pouring concrete.

This tool also offers the best precision for fine detail work, allowing operators to remove a little concrete at a time, such as shaving down high points or blowouts from slurry walls. The chisel doesn’t offer the versatility of

W WW. C O N C RE TE OPE N IN GS.COM

a moil point, but it belongs in every concrete demolition contractor’s toolbox for specialized applications that call for a delicate touch.

Blunt The blunt tool features a flat face with more surface area to deliver a wider area of impact when breaking slab concrete. It is ideal for floors, steel beams encased in concrete, recycling and certain roadwork applications.

What the blunt tool lacks in precision, it makes up for in destructive power. Energy is distributed across the whole face of the tool, covering a significantly larger surface area than pointed tools. This greatly increases overall efficiency.

Working with a blunt tool produces vibrations, which might limit its use in certain situations like indoor and top-down demolition and some road and bridge repair applications.

However, the vibrations also make this an ideal tool for removing concrete from around steel beams. The vibrations encourage the concrete to walk away from the steel, making it easier to remove. This tool can also be used for bridge beam testing since it can create a pocket just small enough to inspect the steel beam beneath the concrete.

Slab Buster For inflicting maximum destructive power, the slab buster, or “elephant foot,” is the most appropriate choice. Like the blunt tool, it uses a wider surface area and can double production of both slab and on-grade demolition. The slab buster is shaped like a bell

and can distribute energy over a surface area three times its size.

The slab buster also creates vibrations and provides very little precision, so it is not ideal for every situation. However, for a thin slab floor with no vibration restrictions, this tool offers maximum demolition efficiency.

The Right Tool for the Job A little forethought can go a long way toward increasing efficiency when it comes to selecting the right tool for the job.

Knowing which bit to use when can speed up production, leaving crews free to move on to the next job that much sooner. For some operations, using a moil point with their remote-controlled demolition machine might be all they ever need, but for those looking to maximize their concrete demolition capabilities, keeping an assortment of tools in their toolbox will increase versatility and efficiency.

Revitalizing the River Popular Riverway Receives Upgrade from CSDA Contractor

T

he San Antonio Street Bridge on the Comal River in New Braunfels, Texas is a popular local destination. On any given weekend, hundreds of people tube down this scenic waterway, floating under the nearly 100-year-old bridge.

Built in 1923, the aging historic bridge contained seven spans measuring 410 feet, but no longer met functional or structural standards. The lack of a shoulder for the 10-foot wide travel lanes and narrow, 4-foot sidewalks posed a safety risk for pedestrians and bicyclists and the 20,000-pound weight limit meant that heavier emergency response vehicles could not cross it.

The Texas DOT and the City of New Braunfels planned a 16-month project to replace the superstructure of the bridge but leave the arches, spandrel columns and substructure in place, supported by concrete box beams. The superstructure would be widened to increase the width of each travel lane to 15 feet and each sidewalk to eight feet. The updated prefabricated deck would have a new weight limit of 50,000 pounds, capable of accommodating all types of emergency vehicles. The project was projected to cost $4.8 million.

CSDA member Texas Cutting and Coring (TCC) was contracted by the job’s general contractor Capital Excavation to plan and execute the demolition of the deck, sidewalks, rails and beams. The planning phase was focused on a saw cutting and lift plan to calculate the weight of each bridge section to be removed by crane. The Texas DOT planned the average lift for the first phase at 20,000 pounds, plus the weight of the rigging. “Capital Excavation is a long-time customer of ours, and we have been working with them for the better part of 20 years. We know the senior leadership very well and have mutual trust, so it makes planning and executing complex

projects like this much easier,” stated Ronnie Wilhite of Texas Cutting and Coring.

The San Antonio Street Bridge job posed many safety hazards. Care had to be taken during demolition and renovation as to not impact public safety, wildlife, river water or the city’s tourism revenue. The general contractor and the city oversaw public safety and suspended recreational traffic under the bridge.

Before TCC started, the GC installed a temporary second deck below the bridge and 15 feet above the water to protect the public and the area below from falling debris.

Strict safety guidelines had to be followed for worker safety due to the obvious fall hazards.

Every crew member working on the leading edge of the bridge was required to wear harnesses and retractable lanyards with anchors. TCC met weekly with their crew to review safety procedures and advise them of what hazards they needed to be aware of.

TCC started demolition on September 25, 2019, removing nine to ten sections each day.

In each planned lift section of the sidewalk and bridge deck, crews drilled four three-inch diameter core holes with Diamond Products Core Bore 744 four-speed core drills for lifting points.

The rigging was done with Monkey Fists.

Working from the south end of the bridge, TCC crosscut into the curb and across the sidewalks, making a total of 22 cuts four feet long each with a custom-built barrier saw and various walk-behind saws, including Husqvarna FS5000, FS6600, FS7000 and FS8400. They used saw blades from Diamond Products and DDM Concut including 18”, 24”, 30”, 36”, 42”, 48”, 54” and 60” diameters.

To release the outside edge of the bridge from the structure, saw cuts were made with the same Husqvarna walk-behind saws at the face of the curb through the deck and bridge bents.

These cuts had to be made in 20-foot sections, two at a time, for the length of the bridge. Walkbehind saws were again used to saw cut the asphalt and concrete deck away from the bridge bents as TCC worked their way off.

Lifting the bridge sections was a challenge, as the south embankment was too steep to set up a crane beside or below the bridge. TCC looked to the southern bridge approach and set up a 550-ton crane, lifting sections of the deck over the water to a staging area below the bridge. Once they passed the halfway point, they Cranes were used to lift the 20-foot sections after each cut.

switched to a 300-ton crane on the north embankment to remove the remaining decking and beams. All the concrete was crushed for re-use in the temporary construction area below the bridge.

The bridge bents were left in place, still attached to the columns as the work moved northward across the bridge. The columns were cut free with Diamond Products track mounted hydraulic wall saws with blades up to 36� and flush cut hydraulic hand saws with 20� blades made by Diamond Products and DDM Concut. After the deck was removed, the bridge bents were rigged and supported by the crane while they were cut free from the columns. TCC was on site for 22 days, but the actual deck demolition took ten.

Tomas Acevedo, TCC general superintendent, oversaw the safety of the crew and daily operation of multiple saw cutting and coring crews of between two to eight employees, depending on the phase of the job. Acevedo coordinated with the general contractor to manage the equipment and crane use, as well as scheduling and production rates. He helped ensure that all safety protections were in place and were properly maintained during the demolition.d REVIEW AND COMMENT ON THIS ARTICLE AT: WWW.CONCRETEOPENINGS.COM

IACDS President’s Insight

W

hen someone leaves a company or organization after 40 years, they usually leave a hole. Here too, Pat O’Brien has handed the helm to his successors after nearly 30 years as CSDA Executive Director. And that’s the special thing: he didn’t leave a noticeable hole. He has managed to prepare his successor so that it is almost not noticeable he is no longer there. Of course, we will miss him. We will miss his humor and jokes in his moderation and leading of the meetings. His smile and sovereignty. It will remain a gap, but thanks to his preparation, it will hardly be noticeable.

It is a familiar face, someone who has been by his side for a long time.

Someone who has supported him for a long time. Someone who knows him almost like no other: it is his daughter Erin.

Thank you, Pat, for 30 years with CSDA and my dear Erin, I wish you all the best for your time as an Executive Director in one of the largest and most important associations in our industry.

At this point I would like to wish another great woman from our industry a speedy recovery. Our past president and my predecessor, Julie White, has been seriously ill since December, so I would like to wish her a speedy recovery from her illness.

Dear friends from the drilling and sawing industry, the year is still young and I am not a fortune teller, but at least we can assume one this year. The economy in the member countries is good and positive on all sides. Therefore, I am in good spirits that we will be able to work through

MICHAEL FINDEIS IACDS President many exciting projects again this year and hopefully get to read about them in specialist magazines such as Concrete Openings.

Last but not least, I would like to remind you once again that we (IACDS) are also celebrating an anniversary and are celebrating this on March 25-26 in Willingen, Germany. For those who cannot participate, we hope to see you at your Annual Convention in Carlsbad, April 2-4.

Until then, I wish you all the best and good business.

Sugar–the Good, the Bad and the Ugly

By Erin O’Brien

W

e’ve all heard it before—sugar is bad for you. More recently, the enemy has been high-fructose corn syrup—a chemically modified version of sucrose (table sugar).

However, even the most basic chemistry or biology class teaches that bodies run on sugar, more specifically glucose—sugar in its most basic form. So how can some types of sugar be good and some bad?

The quick answer to this question is moderation. Almost any type of food we put in our bodies is acceptable and safe, as long as it is eaten in moderation. Glucose, sucrose and fructose are all types of sugar naturally existing in the food we eat. The difference comes from the way our bodies process each type of sugar. Sucrose and fructose are broken down from their more complex structures to make glucose once inside the body, which is then used for cell energy and growth. All three of these types of sugars are naturally-occurring, meaning they are naturally found in foods like fruits, root vegetables and honey. High-fructose corn syrup is chemically modified from its natural form, corn syrup, by increasing the amount of fructose.

The modern problem with sugar, is that as a general population we eat too much of it. Our bodies have a finite amount of sugar that can be processed at one time, and if there is an excess in the body the sugar is converted to fat and stored. Too much sugar in the bloodstream can also raise insulin levels. Insulin is a hormone produced by the pancreas. It tells the body to utilize glucose (sugar) in the bloodstream for energy and also use fat stores if there is not enough glucose in the blood. Too much glucose in the blood, however, will elevate insulin levels and “trick” the body into storing glucose as fat instead of utilizing it for energy.

We all know that excess fat equals excess weight, and excess weight leads to a host of health concerns. The other problem with too much glucose in the blood is that is also raises the level of triglycerides and cholesterol, especially low-density lipoproteins (LDLs). LDL is a type of protein

28 | MARCH.20

that transports cholesterol around the body wherever it is needed. Unfortunately, if there is too much LDL cholesterol in your body, it ends up getting deposited along the walls of your arteries, causing plaques which can lead to cardiovascular disease (CVD).

High-fructose corn syrup can compound this problem. A diet high in high-fructose corn syrup, or any sugar, will cause the liver to convert fructose to fat, also leading to increased levels of LDL. The modern human diet, especially in the United States, is very high in added (or not naturally-occurring) sugars and processed carbohydrates. Combined with a low intake of fruits, vegetables and whole grains, as well as sub-optimal lifestyle habits, physical inactivity and use of tobacco, this is a recipe

for disaster. This type of lifestyle leads to an increased risk of obesity, CVD, type 2 diabetes and cancer. It produces a tremendous amount of premature deaths, lost quality of life and global economic disruption due to skyrocketing health care costs.

Diet soda, perceived by some as a “healthy” alternative, is also to blame. While some think that they are making a healthy choice, there is added sugar in diet soda too. Often times, these sugars more closely resemble chemicals than actual sugar and contribute to an increased risk of developing coronary heart disease, kidney disease and metabolic syndrome. One study shows that middle-aged men and women who consumed more than one diet soda per day had a 30% higher risk of developing these diseases. Those

with the lowest incidence of these conditions drank one or fewer diet sodas per month.

Some recent research has focused on cancer’s relation to sugar in the diet. While no study has been conclusive to date, several suggest that a high dietary sugar intake actually causes some cancer to grow and spread—especially breast and colon cancer. This is because cancerous tumors have insulin receptors that feed on glucose.

If there is too much sugar in the body, insulin production goes up and that insulin tells the cancer cells to grow.

While much of this research is new, there are many cancer and CVD patients that have attested to the success of a low-sugar diet.

We cannot avoid sugar altogether, as it is our body’s main source of fuel and found in most of the foods we eat, but it is important to limit the amount we take into our bodies. This can be easily done by eating a diet high in fruits, vegetables (especially raw) and lean proteins and avoiding processed foods and added sugars and chemicals. Shop the perimeter of the grocery store, as that is where the healthiest foods are, and visit local farmers’ markets for even fresher produce grown with fewer, or no, chemicals.

A healthy diet is a balancing act, but can be done by making smart choices. The long term benefits will far outweigh any perceived negatives and produce a higher quality of life for anyone willing to make the effort.

Awards Concrete Cutters Celebrated at Las Vegas Awards Ceremony The 7th Annual Concrete Openings Awards ceremony was held during February’s World of Concrete international trade show and exhibition at the Las Vegas Convention Center. The awards recognize some of the most innovative and challenging projects completed by CSDA contractors in 2019.

A crowd of show attendees and members of the industry media gathered around the association’s exhibit booth as CSDA Executive Director Erin O’Brien led the proceedings. First held at World of Concrete 2014, the ceremony showcases the best projects covered in CSDA’s official magazine as chosen by a panel of judges, and acknowledges the concrete cutting, polishing, GPR imaging or selective demolition contractors who performed the work.

Job stories featured in the magazine’s four quarterly issues from 2019 were split into four categories and put before the panel. Judges scored each job based on: • Pre-planning • Use of innovation • Degree of difficulty • Quality requirements

The project with the highest score in each category was declared the winner. Display boards of the winning projects were featured at the CSDA exhibit booth during the four-day World of Concrete exhibition, and a special commemorative book was produced for the winners and those in attendance. During the ceremony, O’Brien thanked all the contractors who submitted their projects for publication and congratulated the winning companies.

These winning projects are just some of the complex, painstaking jobs being done by CSDA contractors everyday on jobsites around the U.S. and beyond. The association encourages all concrete cutting, breaking, polishing and imaging members to submit their best job stories for publication in Concrete Openings, and to consider entry to this year’s awards. Look out for more information about the Concrete Openings 2020 Awards later in the year.

Shopping Mall Demolition with Customized Robot Fleet

Diamond Wire Sawing Slices Through 2,000 Tons of Concrete at Texas Port

• Two floors of an operating shopping mall needed to be removed without damaging the existing structure or disturbing the nearby residential neighborhood

• At the Port of Corpus Christi, a $325 million project to expand the port required demolition of existing concrete structures over water and on land

• The distance between floors was 21 feet and the weight limit on the existing floor was 7,000 lb. No robot on the market would meet those standards, so Interstate developed their own custom fleet of five Brokk and Husqvarna demo robots • Over 150,000 square feet of concrete was crushed and removed to create space for the new floors to be constructed • The four-man crew operated in two 10-hour shifts and battled extreme cold, working in confined spaces and working at significant heights

• Mooring structures, buildings, stockpiled concrete, loading docks, foundations and light poles all needed to be demolished and removed, totaling over 2,000 tons of concrete and 1,790 tons of steel • Innovative wire sawing techniques were used to break these structures into smaller pieces to be lifted out and hauled away, all operations completed by Holes. Over 2,200 feet of wire sawing was completed • The team had to contend with strong currents, high winds and waves and heavy fog over a period of six months while pulling double duty cutting, breaking and hauling the concrete and steel for recycling

Safety Counts

Coronavirus Information and FAQs By: Mark A. Lies, II and Daniel Birnbaum

T

his document and the FAQs are intended to provide you with general information about the 2019 Novel Coronavirus including how it is transmitted and how you can prevent infection. It does not constitute legal advice on this topic. This document is not intended to be exhaustive and we encourage you to supplement your knowledge of Coronavirus by visiting the website of the Centers for Disease Control website at www.cdc.gov.

What is Coronavirus?

Coronavirus is a new respiratory virus that originated in Wuhan, China.

The virus is contagious and potentially fatal. It is suspected that it is transmitted through coughing and sneezing of infected

36 | MARCH.20

individuals. At the present time, there is no vaccine, cure or specific treatment.

How is Coronavirus spread?

Health authorities have not confirmed how Coronavirus is transmitted, but suspect it is spread person-to-person.

There is also evidence that the virus has been spread by animal sources, including individuals with links to seafood or animal markets. They do not believe you can get it from air, water or food.

How many people survive Coronavirus?

Currently, Coronavirus has a fatality rate of less than 3%. As such, the majority of those affected so far have survived the disease.

What are the signs and symptoms of Coronavirus?

Individuals infected with Coronavirus have displayed the following symptoms: • Mild to severe respiratory illness; • Fever; • Cough; • Difficulty breathing; and • Death.

How infectious is Coronavirus?

Virus transmission may happen on a spectrum and authorities are not sure if the virus is highly contagious, or less so.

For person-to-person transmission, health authorities suspect the virus is spread through coughing and sneezing, similar to how influenza and other respiratory

pathogens are spread. Health authorities do not believe you can get it from air, water or food.

The incubation period, or the time interval from infection to onset of symptoms, is from 2 to 14 days. During this period, an individual can be infected and spreading the disease although they may not be experiencing the signs and symptoms of the virus.

How can I protect myself?

Because there is currently no vaccine to prevent infection, the best way to protect yourself is to avoid being exposed to this virus. The CDC recommends the following additional steps: • Wash your hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available.

• Avoid touching your eyes, nose, and mouth with unwashed hands.

• Avoid close contact with people who are sick.

• Stay home when you are sick.

• Cover your cough or sneeze with a tissue, then throw the tissue in the trash.

• Clean and disinfect frequently touched objects and surfaces.

What happens if I suspect I or someone I know has Coronavirus?

If you exhibit symptoms of Coronavirus within two weeks of traveling from China, you should contact a healthcare professional and mention your recent travel.

If you have had close contact with someone exhibiting Coronavirus symptoms who has recently travelled from China, you should call ahead to a healthcare professional and mention your close contact and their recent travel. Your healthcare professional will work with your state’s public health department and CDC to determine if you need to be tested for Coronavirus.

Should I consider quarantining employees, or having employees remain off work, who have recently returned from China?

You should consider telling any employee returning from China that they should remain away from work for fourteen days from their return. You can also consider telling the employees to selfmonitor for any symptoms of Coronavirus.

If any of these symptoms occur, the employee should consider being evaluated

W WW. C O N C RE TE OPE N IN GS.COM

by a healthcare provider. Further, even if not symptomatic, employees may also want to consult a healthcare provider to confirm that the employee is not infectious before returning to work.

Should I consider providing information to my employees about the Coronavirus?

Yes. Information is available at no cost on the CDC’s website -- https://www.cdc. gov/coronavirus/index.html.

Can I Restrict Employees from Traveling to China?

Yes. Employers may consider restricting employee travel to the particular areas affected by the disease for business purposes. Employers may also consider requesting employees inform the employer if they are traveling for personal reasons so the employer is aware of employees who are going to areas and are exposed to the disease.

Employees who travel to China need to

C O N C RET E O P EN I N G S | 3 7

Safety Counts

continued

be informed that they may be quarantined upon their return. Employees should also be informed that there may not be adequate medical services available if they travel to China and become ill.

Does FMLA leave apply for employees, or immediate family members, who may contract Coronavirus?

Yes, assuming that the FMLA applies to the employer, Coronavirus would qualify as a “serious health condition” under FMLA allowing an employee to take FMLA leave if either the employee contracts the disease or an immediate family member contracts the disease. The employee would be entitled to job reinstatement as well. State law may provide additional leave benefits.

Would I need to pay workers’ compensation for employees who contract Coronavirus?

Perhaps, if the employee contracted the disease in the course of their employment, that is, does the employee’s work require them to be exposed to persons who are infected, typically healthcare workers? If an employee incidentally contracts the disease

38 | MARCH.20

from a co-employee, there likely will be no worker’s compensation liability. If there is worker’s compensation liability, employers are responsible for covering the costs of reasonable and neccessary medical care, temporary total disability benefits, and permanent disability (if any). Employers should engage a competent medical professional on infectious diseases for advice to determine whether the disease is work-related.

Would I need to pay my employee disability benefits if they contract the Coronavirus?

Yes, if such payments are provided in an employer’s benefit plan. Employers should review the limits of coverage in the benefit plan to ensure they have competent medical resources to administer the program.

Does the ADA restrict how I interact with my employees due to the Coronavirus?

No. The ADA protects employees with disabilities, but during a global health emergency, as recently declared by the World Health Organization, employees can

be required to be medically examined to determine if they have contracted the disease. Also, voluntary medical exams are always permitted, if performed confidentially. The EEOC has suggested materials to distribute to the workforce in the event of global health emergency.

The ADA protects qualified employees with disabilities from discrimination.

A disability may be a chronic physical condition, such as breathing. Employees may be entitled to an “accommodation” such as leave or be allowed to work away from work for a limited period. Employees who have contracted the virus must be treated the same as non-infected employees, as long as the infected employees can perform their essential job functions. If the employee poses a health or safety threat to the workforce, the employer may place the employee on leave.

Has OSHA provided guidance on how to handle Coronavirus?

OSHA has issued a fact sheet regarding protecting workers in the case

www.lissmac-usa.com of a global health emergency. Per, OSHA employers should train employees on the following: • Differences between seasonal epidemics and worldwide pandemic disease outbreaks; • Which job activities may put them at risk for exposure to sources of infection; • What options may be available for working remotely, or utilizing an employer’s flexible leave policy when they are sick; • Social distancing strategies, including avoiding close physical contact (e.g., shaking hands) and large gatherings of people; • Good hygiene and appropriate disinfection procedures; • What personal protective equipment (PPE) is available, and how to wear, use, clean and store it properly; • What medical services (e.g., vaccination,

W WW. C O N C RE TE OPE N IN GS.COM

post-exposure medication) may be available to them; and • How supervisors will provide updated pandemic-related communications, and where to direct their questions.

Can OSHA cite an employer for exposing my workforce to Coronavirus without protective measures?

Perhaps. OSHA regulates safety hazards through its “general duty” clause that applies to “recognized hazards” in the workplace. OSHA will look to the CDC as authority when issuing such citations.

The agency will determine whether the employer’s industry, “recognized” that exposure to infected individuals in the workplace is a hazard. If so, the agency would expect the employer to take feasible measures to protect the employees and, if not does not take such action, the employer could be subject to citation. Employers should conduct

a hazard assessment for potential exposures and develop an action plan that includes hazard identification, hazard prevention procedures, employee training, medical monitoring surveillance and recordkeeping.

CONCLUSION The foregoing information is provided based upon currently known information.

The progress of this disease is constantly evolving. The foregoing information is subject to change based upon such evolving information.

WHAT LIES BENEATH GPR Locates Concrete Slab Embedments Missed by Passive Scanning

40 | MARCH.20

uring the construction of a new auto dealership in Pennsauken, NJ, the general contractor (GC) ran into a problem. They could locate no prints or as-builts for the building addition they were working on, and there were no known sanitary lines under the floor. They were contracted to install bathrooms, so the plan was to tunnel under the building’s footer to a known sanitary line outside of the building.

The GC needed a scan of the floor before sawing the trenches. They called on the services of CSDA member Ground Penetrating Radar Systems, LLC (GPRS) to scan the floor to discover what, if anything, lay below.

The floor was simply an open concrete slab on grade with sectional carpet. When GPRS technician Benjamin Iles arrived,

W WW. C O N C RE TE OPE N IN GS.COM

he noticed only a couple of wall panels and no mechanical or electrical rooms nearby. He had an electrician open the wall panels but saw no conduit penetrating into the slab.

With a Radiodetection RD 4000, GPRS ran a passive mode locate scan over the floor with the carpet in place. The results were negative – nothing was found below the slab.

But when the area was scanned with a Conquest 1000 MHz GPR concrete scanner, several anomalies and unknown objects were revealed.

“I ended up coming across surface features that were covered over with the carpet and a bit of concrete, including several buried cleanout lids, unknown utilities running just underneath the slab, an elongated disturbance in the slab and an unknown circular lid,” said Iles.

GPRS and the plumber pulled back the carpet above the anomalies and discovered cleanouts and access lids for Walker Ducts. They broke open the cleanout lids and with an Envirosight Verisite camera and duct rod they found out that the cleanout lids led to utility lines connected to the

sewer outside the building - the same sewer line the GC was contracted to tunnel to. With the Bluebeam drawing app for iPad, GPRS scanned an existing floor plan and overlaid the findings by hand. The cleanout lids were later confirmed to be an abandoned sewer line just under the building’s slab, and once inspected and cleaned, it could be used.

GPR helped the client save money on the project, as the original plan for tunneling under the footer could be abandoned.

The GC was able to demo the floor safely, as they understood where the utilities and anomalies were located under the slab and could tie in the plumbing inside the building where they were saw cutting. Once again, a CSDA member helps to save their clients time, money and resources.

GSSI’s first GPR system - and the first commercial system sold in the world - was introduced in 1971, and we’ve come a long way since then. It was followed by a series of other “firsts”: including the first portable GPR, the first system capable of real-time data processing, the first system for rebar location, the first multi-channel GPR array, the first system for search & rescue and the first GPR system for measuring pavement compaction, among many others. This past year, we were the first to commercialize a GPR system for localization – an application that promises to solve one of the most difficult hurdles for autonomous vehicles: navigating in bad weather and winter conditions. Our commitment to push the boundary of technological innovation has never been stronger,” said Christopher Hawekotte, President of GSSI. “We would not have been able to achieve these milestones without recognizing our amazing employees. Our company has grown from that two-person team in a garage to one that now employs almost 100 people in a modern 72,000 square foot facility in Nashua. In 2019, we were proud to be named the Best Place to Work by Business New Hampshire magazine, and to have been recognized as a Presidential E-Award recipient by the U.S. Department of Commerce. It’s been a tremendous 50 years.”

Recently, Senator Jeanne Shaheen met with GSSI employees and toured their headquarters. “Over the past five decades, GSSI has grown into a globally recognized leader in hightech innovation and has strengthened the New Hampshire

economy in the process,” said Senator Shaheen. “This success is a testament to the quality of their cutting-edge products, as well as the dedication of their skilled workforce. Congratulations to GSSI on celebrating 50 years in business and best wishes for the next 50 years.”

GSSI invites their customers to celebrate with them throughout the year.

Events include special recognition at the World of Concrete and ConExpo, a guest lecture series, customer success stories on the blog, and a glimpse behind-the-scenes on our social media channels. In their annual calendar, product timelines, industry innovations, and company history are weaved together with customer survey photos. Connect will GSSI at www.geophysical. com or their social media channels to follow along.

Vacuworx Introduces Even Smarter Portable Lifter It’s been said that big things come in small packages. The next generation of battery powered lifters from Vacuworx really puts that theory to the test! The new PHD Portable Vacuum Lifting System weighs just 25 lb (11 kg), yet it generates enough power to lift up to 2,500 lb (1.13 tonne). With smart features like a remote control, lithium battery and dual pump design, the PHD is ready to prove how it can help contractors work FASTER, SAFER and SMARTER! Our customers asked and we listened. One of the most common requests we received from the popular PS 1 Portable Vacuum Lifting System was to incorporate a remote control so that the operator doesn’t have to be right next to the unit to turn it on and off. In addition, the remote allows the PHD to be used in more applications and on more host machines.

The PHD is equipped with a 12V 30 amp/hour rechargeable LFP (Lithium Iron Phosphate) battery which is designed to provide longer

W WW. C O N C RE TE OPE N IN GS.COM

run time and overall longer battery life. The lithium battery is significantly lighter than traditional dry cell batteries, so you don’t have extra weight to carry around. The battery charger is fast and efficient—simply plug the system in at night and be ready for another full day’s work in the morning.

The PHD features two dual-stage vacuum pumps to build vacuum faster. The system is engineered to draw less power from the battery, while providing a deeper vacuum than single stage pumps. In addition, the PHD releases vacuum more efficiently to increase productivity.

The PHD is designed to absorb vibration from the pump for quiet operation. An inline filter protects the system from dust and debris; the filter element is easy to replace when it becomes clogged or dirty, which prevents damage to the system. Hoses have quick connections to both the unit and the pads, and the PHD is equipped with visible and audible alarms for safety.

Vacuworx offers mounting assemblies to facilitate the use of the PHD on mini skid steers, mini excavators, forklifts, small cranes and Husqvarna demolition robots.

Hilti Achieves Further Sales Growth The Hilti Group grew sales by 4.3 percent in the 2019 business year to CHF 5.9 billion. In local currencies, growth was 6.3 percent against the previous year.

“2019 was another successful year for us with exclusively organic growth. The economic environment has become more volatile while global construction growth has noticeably slowed. Additionally, currencies largely displayed depreciation tendencies against the Swiss franc. Against this background we’re satisfied with our growth level and are pleased that we gained additional market share,” commented Hilti CEO Christoph Loos on the developments in the 2019 business year.

“Hilti North America is pleased to be an important contributor to the growth of the Hilti Group in 2019,” observed Martina McIsaac, Region Head and Chief Executive Officer of Hilti North America.” Turnover in North America increased 8.6% in Swiss Francs (7.3% in local currencies).

As with all Brokk machines, the four new rental units feature Brokk’s three-part arm for exceptional reach and movement, as well as industry-leading power-to-weight ratios. The compact B110 features a 10-foot (3-meter) reach and weighs 2,183 pounds (990 kilograms). Equipped with a BHB 155 breaker, it delivers 187 foot-pounds (254 joules) with each blow. The B170 can reach 16 feet (4.8 meters) vertically and 14 feet (4.4 meters) horizontally.

Paired with a 452-pound (205-kilogram) BHB 205 Hydraulic breaker it delivers 299 foot-pounds (406 joules) of power. The B200 represents a new weight class for remote-controlled demolition machines and features a 15% longer vertical and horizontal reach than the B170.

Aquajet Introduces Powerful Aqua Cutter 710V for Heavy-Duty Concrete Removal Aquajet, a global leader in hydrodemolition machine manufacturing, offers its farthest-reaching unit, the Aqua Cutter 710V Hydrodemolition robot. It’s the largest of its kind and offers exceptional horizontal, vertical and overhead reach — as high as 23 feet. The 710V comes equipped with Aquajet’s hallmark ceramic nozzles that last as much as 79% longer than standard steel versions.

Its design makes it suitable for a wide variety of concrete removal tasks, such as renovation and bridge and road repair.

The 5,070-pound (2,300-kilogram) Aqua Cutter 710V uses 14,500- to 40,000psi water jets to remove as much as 35 cubic feet (1 cubic meter) per hour of concrete. Contractors adjust the robot’s stroke to control the depth of cuts and vary the pressure of the water jet depending on whether they are removing loose, deteriorated concrete or lowering the sound concrete to a pre-determined depth. A valuable feature of hydrodemolition is that rebar is cleaned and descaled during the process, whereas alternative methods, such as pneumatic tools or milling machines, may damage the rebar or produce microfracturing in the remaining concrete.

Operators can control the 710V from a safe distance using the unit’s radio remote control, either wirelessly or with a hard wire. The remote communicates with the robot’s wheeled power control module.

TESTIMONIAL

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.

Real Power has been in the generator business since 2004, but a few years ago when we first began to work within the concrete industry there was a lot we needed to learn, and fast. CSDA was extremely open and willing to bring their decades of experience working with and promoting the industry to help us understand its unique power requirements and operating constraints.

After we were invited to join our first CSDA Convention and Annual Meeting, there was no going back. The CSDA organization and the CSDA community as a whole welcomed us and showed a great willingness to give us a shot, help us grow and become a trusted partner industry-wide.

We’re extremely proud of where we are and where we’re going, and this organization has been a huge part of making it possible.

Director’s Dialogue

Change

ERIN O’BRIEN Executive Director

“Never doubt that a small group of thoughtful, committed, citizens can change the world. Indeed, it is the only thing that ever has.”

T

his quote by Margaret Mead perfectly sums up the history of CSDA in my eyes. As we approach our 50th Anniversary in 2022, this is an appropriate time to reflect upon where we have been and where we are going.

Started in 1972 in California by a group of competitor contractors, these founding CSDA members saw beyond their individual companies and personal conflicts to band together and forge a new path for this fledgling industry. Nearly 50 years later, the results of their vision and dedication have resulted in a unique industry that has given most of us successful businesses, lifelong friendships and a sense of accomplishment.

However, we as an association have come to an impasse.

We can no longer do things they way they have always been done, because the world is not the same. A new generation prioritizes family more than ever. Technology enables communications to happen instantaneously and everyone expects immediate results. Priorities have shifted, resourceful companies have learned how to market themselves via social media, altering the historical necessity of in-person networking.

I am excited about these challenges and the opportunities they bring to CSDA.

60 | MARCH.20

I begin my tenure as Executive Director during a challenging time. Our entire landscape is shifting. While my official involvement in CSDA began only 10 years ago, my immersion in the association began many years before. If you called the CSDA office in 1995, and a young girl’s voice was on the other line, you were probably talking to me. My father, Pat, would bring my sister and I to the office nights and weekends to assemble mailings, make copies, build the database and answer the phones. Like so many others in leadership positions today, I’ve been a part of CSDA for most of my life. I have seen the association grow, adapt, shift and change. And we need to change now more than ever.

This will not be an easy change, and it will not happen overnight. But I firmly believe we have the right Officers, Board, committee members and staff in place to make this a successful transition. We can’t do this without our member support however, and I encourage each and every one of you to reach out to me and share your thoughts, vision and what you need from CSDA in the next 50 years. I look forward to hearing from you and am excited to start this new journey.

“If I am an advocate for anything, it is to move. As far as you can, as much as you can. Across the ocean, or simply across the river.”

—Anthony Bourdain
