JUST A FEW NOTABLES

For many of you out there, I’m hoping “construction season” has already begun. Here’s to being safe. Here’s to being successful. Here’s to being busy.

Among the metric ton of content found within this issue, I’d like to draw attention to three pieces:

Inside is a short piece on concrete paving equipment and slipformers (page 18). When I started asking about how the concrete paver and slipfomer has changed over the years, my original plan was an article about the equipment. The assumption was I would be writing about industry-breaking innovations or improved spreaders and screeds for higher-quality placement. While the machines likely having improved slightly over the years, I learned instead that any discussion about concrete paver equipment also includes the machines and technologies in support. How stringless technologies have improved precision. How the equipment width capabilities have increased—and the need for a source (concrete plant) capable of keeping the concrete supply going.

Since we’re on the subject of “improvements” within construction and concrete contractors, Concrete Contractor is overjoyed to announce this year’s Top Products winners (page 28). Concrete Contractor’s Top Products award recognizes the innovative products, tools, machines, solutions, and equipment designed for the concrete contractor. Winners of the Concrete Contractor Top Product Award are designed to not only help overcome the challenges contractors face daily but do so with innovative ideas and ingenuity setting contractors up for success in the years to come. Join us as we recognize all these great products, tools, and equipment.

Another special addition to this article is a piece by Cal Beyer and Scott Kubiszewski of DPR Construction (page 22). The story is about how Scott and drove the support to have Naloxone available on construction jobsites, later forming with Alliance for Naloxone Safety in the Workplace with 23 founding members. In some exciting news—since co-authoring the article, Cal has been hired on the SAFE Workplaces team as senior director for the national nonprofit SAFE Project (Stop the Addiction Fatality Epidemic). SAFE Workplaces is an organization that supports businesses like yourselves with programs on substance misuse/disorder and mental health.

There’s a lot more so I hope you enjoy this issue. Stay safe out there.

FAE RPL/EX FIXED TOOTH ROAD PLANER

FAE has expanded its construction line with the RPL/EX road planer for excavators with specially designed teeth specifically for use on asphalt and concrete road surfaces. The new road planer for excavators is based on “cold planer” technology. With cold planer technology, the road’s surface is scraped and cut by the impact of special teeth attached to the rotor. The RPL/EX has a specially designed layout to reduce vibration. With these features, the RPL/EX can be used to prepare roads for resurfacing or to support excavation operations. The RPL/EX is compatible with excavators from 8 to 14 tons, can mill up to 5.3 in. deep and has a working width of 18 in. The head comes standard with technological and structural features. These include an adjustable hydraulic base that allows you to manage the machine’s working depth, a wide-stroke self-leveling system that allows you to keep the head properly aligned while in operation and an adjustable right skid that allows the operator to keep the head aligned in overlaps.

A MILESTONE OF SUSTAINABILITY

MILESTONE CONTRACTORS USED RECYCLED MATERIALS, RECLAIMED WATER, AND CAPTURED CO2 FOR THE CONSTRUCTION OF RUNWAY 5R-23L AT THE INDIANAPOLIS INTERNATIONAL AIRPORT.

The Indianapolis Airport Authority received an Envision award by the Institute for Sustainable Infrastructure for the innovative and environmentally sustainable approach to a reconstruction project for the Indianapolis International Airport (IND). When it came time for the concrete pavement replacement of runway 5R-23L and taxiway D, they turned to local concrete paving company Milestone Contractors to earn a second.

The work done earned an Envision: Plutonium award in 2023.

Based in Indiana and one of the larger contractors in the state, Milestone is a multifaceted company, providing services for concrete and asphalt construction. Not one to shy away from a too large or too small of a job, they work on everything from bridges, curbs, sidewalks, driveways, work for the Department of Defense work, as well as airports. As Steve Friess puts it, “We pretty much cover the whole gamut.”

Friess is the vice president of concrete operations at Milestone. He’s been with the company for 11 years and has an extensive background in concrete paving. For those in the Indiana concrete pavement world, if the name sounds familiar, it should. He was named Chairman of the Board of the American Concrete Pavement Association (ACPA) in December 2022. In his nearly 40 years of experience in the pavement industry, Friess has enhanced Milestone’s concrete offerings by developing Heritage Construction + Materials and seeing the company earn accreditation in ASHTO R-18 and ASTM C1077. Ernie Peterson from Ash Grove Cement Company is the current ACPA chairman.

While Milestone does put down a greater amount of asphalt, its concrete work is still nothing to scoff at. Friess expects Milestone to place 3 million tons of asphalt and about 700,000 yards of concrete this year. The company has a ready-mix division and owns seven portable plants they move around for airport and freeway jobs.

Milestone is owed by The Heritage Group, a fourth-generation family-owned business out of Indianapolis led by Amy Schumacher, chief executive officer. “Even as big as we are,” says Friess, “they are still very family-oriented. Milestone has a motto that says ‘We make lives better one road and bridge at a time.’”

The Heritage Group celebrated 90 years in business in November 2020. In the 1930s, John Fehesenfeld opened a residential home heating oil delivery service which evolved into a brand of convenience stores and eventually sold to Speedway. In the 1950s, the company moves into the paving industry with Fehesenfeld’s sons at the helm. Milestone originally began as Columbus Paving Company in 1954 by the Meshberger family and Herman Newen, after several mergers and purchases, it eventually became Contractors United Incorporated (CUI) in the 1970s and made of a unification of a handful of local companies—making it the largest construction firm in the area in 1971. CUI, Fauber Construction Company, and Astro Paving joined to become Milestone Contractors LC in 1994. They added Speedway Co. in 2022 to supply ready-mix concrete.

“With this new paver and the QC team that I have, they were spectacular from day one. In fact, the first day I kind of looked at it and said, ‘If this goes this good the rest of the time, we’re going to be golden.’ It even went better. We had a great team out there. I can’t say enough about the team we had, they were spectacular.

We had to have a plant that would do 500 yards an hour. It would do 600 yards an hour if there was the area for it – that’s almost a load a minute for 10-yard loads. It will produce more concrete than you know what to do with sometimes.”

PHASE ONE

Phase one was the center point of the runway and taxiway 23, the middle

5,000-6,000 ft. of an 11,000-ft. long runway (plus a little).

This also included the adjoining taxiway in front of the FedEx location – a major hub for the airport (the second largest in the country for FedEx).

Milestone was hired for the second and third phases of the project. Phase

PHASE TWO

PHASE TWO

Milestone was hired for phases two and three. At about $88 million, according to the request for bids document, major work items for phase two included:

• 79,000 square yards of concrete pavement removal

• 104,000 square yards of P-501 concrete pavement at 37.5 ft. wide, 22 in. thick

• 104,000 square yards of asphalt pavement removal

• 52,000 TN

• 54,000 cubic yards of unclassified excavation

• 75,000 cubic yards onsite borrow

• along with work in storm sewer, watermain, airfield electrical, signage, lighting, NAVAIDs, and pavement marking

Aside from the men and women of the Milestone crew, carrying the load of the major paving work was GOMACO equipment. The paving line included two spreaders (a second with a conveyor to increase production), a GP4 slipform paver, and dump trucks to transport the concrete mix from an Erie Strayer concrete plant. They used a portland limestone cement from Buzzi Unicem USA and injected captured carbon into the mix. Milestone purchased the GP4 about four years ago, paving up to 30-32 ft. for different interstates. When they were finally awarded the job, they also purchased a PS460 placer/spreader—capable of paving to 40 ft. wide.

Having paved for the Atlanta Hartsfield and Cleveland Hopkins airports previously, he’s had experience paving to 37.5 ft. before. Friess’ advice: “it all comes down to good mix and good setup on your equipment.” Needing to pave 22 in. of concrete, the challenge in Indianapolis was the depth. While they had worked on 18 in. before for “fill-in” work. Indianapolis required them to pour without forms reinforcing the need for a good mix. The concrete was specified to be 625 psi in accordance to FAA flexural strength tests with a 0.25 to 0.5 slump. Their test lab was able to keep on target to avoided any panel removals due to strength. The pavement was finished with transverse grooves.

Ultimately, they recycled the existing runway and asphalt shoulders for base material.

RECYCLED MATERIALS

• 135,000 cubic yards of the existing runway into base material

• 65,000 tons of asphalt from shoulders for under the pavement and shoulders

• Reused more than 4 million gallons of water

Friess explains that most of the construction was kept to a centralized location onsite to minimize the carbon footprint of the project. Crushed concrete pavement was pulverized into multiple sizes for the reuse of base materials, pipe backfill, and a special fill for lighting. “In the words of sustainability, this is what it was all about… because these quantities are just unbelievable,” he notes.

Conventional concrete sealers don’t last. PoreShield™ does.

It absorbs deep below the surface to block salt and moisture damage for 10+ years.

Plus, it’s non-toxic, easy to apply, cost-effective and sustainable.

As the breaker shattered the pavement, off-road trucks hauled material a short distance—less than 1,500 ft.—into a pile. While Milestone were able to recycle themselves, they subcontracted it out to a crushing company from Chicago. “This was such a mammoth project, we figured we’d let them do it,” says Friess. “Since then, they have crushed almost everything that they had onsite at the airport above and beyond our current job. We had them crush at least another 150,000 tons of this material that they’ve used on other projects at the airport.”

The concrete runway included 2 in. dowels in both directions on every joint cut into 6 ft. sections to help with the weight. “If you pick six 18.5 lbs. dowels, plus the weight of the basket unit itself, you’re like 120 lbs. for a six footer. We were pouring 30-37.5 ft. across, so there’s no way to pick up 36 ft. of dowels.” A Minnich drill made quick work of drilling the 2 1/8 in. holes.

No one said concrete work was easy. “Just the fact of putting in 500 bars a day at just under 20 lbs. a piece, you know, that’s a lot of weight,” says Friess. “The whole crew worked very hard.”

PHASE THREE

PHASE THREE

Phase three is on the far west end of the airport which includes the construction of a 5-acre $15 million solar panel field. “With the solar, we’ll actually be able to do one of the complete runways at the airport. Going back to sustainability and all that, the Indy airport is really probably ahead of the times in that kind of work,” comments Friess.

According to an announcement from IND in July 2023, phase three is being funded by the nation’s largest allotment of funding via the Airport Improvement Program of the FAA: $22.58 million. The funding is part of $92 million to help airports reach the net-zero emissions by 2050.

Sustainability efforts also included injecting CO2 with technology from CarbonCure into the concrete mix to encapsulate the captured carbon. Unfortunately, the carbon injection plans didn’t go exactly as intended. While injection was successful, Milestone wasn’t able to get captured carbon close enough to the plant to make it a viable option and had to purchase carbon from within a 60-mile radius.

With carbon injection, Friess says that they might have been able to conduct tests to potentially reduce cement content after some time. However, the pouring ended before they were able to do so.

Signage and constant reminders urged everyone to keep trucks off to keep emissions down.

Waste and water sources were another issue. Milestone set up three settling ponds to capture water and used an ozonator to oxygenate and help clean the water. They used this as well as any collected rain water to spray the grade for dust control and compaction efforts. They kept track of every tanker load, how many times they filled the truck up, and where it was filled (pond or hydrant). “After a big rain, there were four ponds around the airport that would fill up and we’d go

suck it up out of there—there was a lot of effort made to recycling everything.”

This project exemplified the value of organization and communication. “We learned sustainability isn’t a bad word…with good organization and good communication, you can run one of these jobs and you don’t have to work day and night, seven days a week.

When we got down to the end, when we were paving, we were working 10-hour days, and still getting our 200-300 yards a day. We found out we don’t have to work 24 hours a day, 365, seven

days a week. You just don’t have to. You just have to be organized and have a plan.” Beyond that, he strongly suggests any concrete paving contractors to join the national ACPA and attend the airport workshops.

WITH CONCRETE PAVING, THE WORD IS

STRINGLESS

A

AT HOW THE CHANGING TECHNOLOGIES OF CONCRETE PAVEMENT EQUIPMENT HAVE ADAPTED TO THE INDUSTRY.

Any investigation about how pavers and slipfomers have changed starts with a simple question. But instead of discussing the machinery involved, it became a conversation on the supporting technology for the machine and the concrete paving crew.

“The buzzword is stringless,” says Stephen Bullock, president of Power Curbers Companies. “It’s been batted around for 15 years, 10 years ago we started seeing some real interest. Over the last 5 years, it’s moving toward becoming the norm.”

Like many, Hi-Way Paving Inc. paves stringless. They started back in 2008 as one of the early adopters using radio communication but often found interference on the signal troublesome. While the radio and antennas improved, around 2020 they opted to use a long-range Bluetooth system. It provided a similar range but allowed more precision in the work. As Matt Landers, machine control and survey manager for Hi-Way, explains it, Bluetooth helps them to keep adjustments tight within their tolerance. Reportedly, they say that the Bluetooth system can reach out to 1,000 ft. but 500-600 ft. pushes the limits. They keep it between 300-350 ft.

“It’s been a game changer for us,” says Landers. “It’s less wiring. Before, you had four radios on the paver that had to be wired to the computer. Then the computer was wired to the paver—we’re talking masses of wires you’re hooking up every morning. It takes you about 20 minutes to pick up all these wires onto the paver. Now it’s as simple as go up, clip the computer and we’re ready to go.” Hi-Way uses GOMACO pavers with Leica total stations. They’re upgrading their mainline spread with a new GP4 set for delivery in Spring 2024 and having a two-track model from 2008 sent out for refurbishing.

The money savings for the setup time was a boon by itself. “That’s money saved there,” says Ed Wessel, president and CEO of Hi-Way Paving Inc. “Going back to when we first started stringless in 2008…the labor savings from setting stringlines and pans…that was transformative for us.”

Paver and slipform equipment manufacturers like GOMACO and Power Curbers work directly with the big three providers like Leica, Topcon, and Trimble, adapting so that the machines are nearly plug-and-play. Many modern slipformers have now integrated electronic sensors in lue of hydraulics.

Stringline was the standard in the industry 20 years ago when Power Curbers launched into the industry (2002).

“When the 3D technology started improving and getting to a point where it met our specifications, it was a big step to be able to eliminate having to set up that stringline and start using 3D or GPS signals,” says Bullock.

“It’s definitely come up with the times. It’s a lot better than it used to be,” says Landers, referring to concrete paving. His team used to have a number of steps when changing total stations including stopping the paver completely. Instead, they keep rolling with the communications system able to jump to the next station.

EMISSIONS

Like many in the concrete construction industry, concrete paver and slipform equipment manufacturers are doing their part in reducing CO2 emissions. GOMACO, for example, announced its GT-3600 Hybrid machine utilizing lithium-ion batteries to provide supplemental power to the diesel engine.

As the describe it, the exclusive G+ control system switches the

48-volt generator from recharging the battery to providing extra horsepower to the 74 hp engine. Reportedly, it should provide an estimated 10-15% fuel savings and “eliminates the inconvenience and extra expense of DEF.”

Bullock sees the potential in fully electric equipment, but jobsites aren’t quite ready yet. “There are real issues with the size of the batteries required and what that would do to the size and the cost of the machine…and then how long that charge would last. There’s still definitely some hurdles, but we are exploring everything including hydrogen,” he says. He likens the change to a football field, placing a fully automatic/ fully electric situation at the end zone. Today, he says we’re at our own 20/30yard line.

With remote operation technologies and sensors, the potential of a fully-electronic and automated machien may be there but it’s a long way away. If we ever reach that end-zone, there will always need to be someone involved.

“I can see someone in our office, running that machine from the office and paving without a lot of big crew around it… we’ll always have guys around the paver checking the concrete and all that but the machine’s got to do all the work, the heavy lifting. I can see that going more in autonomous operation for the paver,” says Wessel. Wessel also recognizes the potential for artificial intelligence to step in the direction of creating project drawings and CAD files—provided a person checks the work, of course. “Time-saving. That’s the big thing,” says Landers.

According to Jason Hogue, vice president of Flores Automation & Machine Control LLC, an authorized national distributor of Leica Geosystems paving products. It’s estimated that 95% of members of the American Concrete Pavement Association use 3D stringless paving.

“From the time we get the project until the time we start the project, it’s usually a 2-3-month lull in there. It takes me a good bit of that time just to get

everything built and ready to go in the field. With progressing technology…I can do it half that time.”

“The focus of manufacturers is on anything using technology to help in reducing labor,” says Bullock. “Making sure we’re keeping up with the trends, sustainability, and making sure we provide contractors what they need when their state or federal government requires it.”

CROWDSOURCING

SAFETY

FORMING THE ALLIANCE FOR NALOXONE SAFETY IN THE WORKPLACE.

In the summer of 2022, while working for DPR Construction Scott Kubiszewski was spearheading an initiative to consider stocking naloxone on all the company’s jobsites in the Pacific Northwest. Kubiszewski was growing increasingly aware of the rising rate of both fatal and non-fatal overdoses attributable to opioids. Kubiszewski was knowledgeable about the benefits of stocking naloxone in the workplace to help reduce the risk of overdose for opioids. Naloxone (also known as Narcan) is a medication that reverses the effects of opioids and is used to help save lives by administering it to persons experiencing signs and symptoms of overdose.

Unfortunately, Kubiszewski and other safety/health practitioners were receiving pushback and resistance from other industry professionals about potential legal and risk management concerns about stocking naloxone in the workplace. He reached out for guidance; we previously collaborated on workplace suicide prevention initiatives. I provided resources to Kubiszewski regarding state-by-state

laws for both naloxone access and Good Samaritan provisions. I also advised that the US Food and Drug Administration (FDA) was considering approving naloxone for over-thecounter use, but that approval was not expected until 2023.

NALOXONE AS THE NEW AED FOR WORKPLACES

Kubiszewski secured support from DPR Construction to move forward with stocking naloxone on the company’s jobsites in the Pacific Northwest. He often cites how early adopters were quickly viewing naloxone as the new AED on jobsites. AEDs are automated external defibrillators used to revive persons in cardiac arrest. Kubiszewski recounted the rapid adoption of AEDs in workplaces and on jobsites once the initial resistance was overcome. “A dozen years ago, AEDs were rare on jobsites and today they are commonplace,” exclaimed Kubiszewski. He imagined “how many lives might be saved if naloxone were available in first aid kits throughout the construction industry.”

FORMING THE ALLIANCE FOR NALOXONE SAFETY IN THE WORKPLACE

By the fall of 2022, Kubiszewski expressed a desire to form an industry workgroup to further collaborate on developing starter resources for companies interested in stocking naloxone in company workplaces and jobsites. He asked Beyer for guidance since his efforts years earlier led to the formation of the Construction Industry Alliance for Suicide Prevention. Beyer offered to help Kubiszewski identify a group of likeminded national safety/health and wellbeing leaders from various disciplines to brainstorm the needs of the industry to help expand the adoption of naloxone on jobsites. Twentythree founding members of the Alliance for Naloxone Safety in the Workplace (ANSW) agreed to collaborate. A list of all founding member organizations is prominently posted on the ANSW website.

Kubiszewski says, “The group quickly morphed to an active team comprised of various construction industry stakeholders, including contractors/employers, labor unions, trade associations, mental health advocates, population health and employee benefit service providers, and other industry professionals.” The group instituted working subcommittees with assigned chairpersons and accountability standards for updating the group on action steps taken since the most recent prior biweekly meeting. Kubiszewski shared how alliance leaders “worked diligently and with urgency.” He states that the group was “aware of the desperate need to reduce potentially preventable overdoses by educating and equipping all industry stakeholders on the benefits of providing naloxone in the workplace and on jobsites.”

The much-anticipated FDA approval of naloxone in March 2023 for over-the-counter sales helped “grease the skids” for the ANSW. Demand for informational resources, policy

guidance, and training support relating to naloxone across all industries has grown exponentially. Various nonprofit organizations have been ramping up resources to support employers seeking to become trained on using naloxone in the workplace. According to Jeff Horwitz, CEO of the national nonprofit SAFE Project, “This is great news because it not only provides us with an opportunity to help employers protect their workforce today from overdoses, but it also allows us to discuss little-known alternatives to opioids as well as first dose prevention techniques to manage pain to better protect their employees and family members in the future.”

STIGMA AS THE MAJOR BARRIER

A guiding principle of the ANSW leaders was to help employers in all industries overcome common obstacles in considering stocking naloxone in workplaces and jobsites. The group wanted to expand awareness of the risks posed by opioids and increase the adoption by employers of naloxone in workplaces. The group identified the biggest obstacle to overcome is the stigma and judgement associated with substance misuse and overdose prevention. Stigma creates a barrier that limits workers and their family members from seeking access to treatment and recovery programs. Stigma also commonly restricts some employers and labor organizations from discussing addiction and taking measures to educate employees and families about treatment options.

OTHER BARRIERS TO OVERCOME IN SUCCESSFULLY DEPLOYING NALOXONE IN WORKPLACES

Beyond stigma, the Alliance for Naloxone Safety in the Workplace recognized that other barriers needed to be overcome. The major barriers challenging employers and labor unions seeking to stock naloxone in the workplace and on jobsites include the following factors:

• Understanding state-specific Good Samaritan and Naloxone access laws

• Instructing employees and posting signage highlighting the availability of naloxone

• Educating employees on the common causes of opioid overdose

• Recognizing the signs and symptoms of an opioid overdose

• Developing a written policy with operating procedures to ensure clear understanding of where to stock naloxone, when to administer doses, and the need for prompt medical attention for a person after the administration of naloxone

• Ensuring adequate training of staff responsible for the administration of naloxone

• Obtaining multiple doses of naloxone and being prepared to quickly replenish supplies of naloxone after doses were administered procedures. Founding member MindForge produced a standardized training video that can be downloaded for free as well.

The ANSW is quickly spreading across the industry to reduce the risk of opioids and prevent overdose deaths. This expanding social movement has the potential to save lives by educating millions of construction stakeholders on opioid risk reduction.

MOCK IT UP: REPAIRING CRACKED POLISHED CONCRETE

KEY STEPS TO TAKE WHEN THE INEVITABLE HAPPENS.

Given time, concrete will inevitably crack. Concrete doesn’t care if it was placed for a warehouse, dining room area in a new restaurant, or an older concrete floor. Despite being a seemingly straightforward process, a crack repair can easily fail if not done properly. After assessing the damage, Nick Demonte, ITF cement mason coordinator for the Operative Plasterers’ & Cement Masons’ International Association (OPCMIA) suggests that the first step be plan and prepare a mock-up.

“Setting the customer’s expectations is the number one priority,” Demonte says. Whether you’re working with an owner of the building or the general contractor, having a meeting with them is going to be vital at the beginning of the job. Doing a mock-up will be instrumental in ensuring all parties involved understand the cost of your repair and the scope of the work.

Since everyone will want to see how their newly repaired floor may eventually look, making a mock-up will help manage expectations, but Demonte advises doing so in the

worst area of the floor: the space that’s beat-up the most. Size your mock-up based on how much work will need to be done. Among the many factors, consider if bolts are popping up, trenches installed, required saw cuts, staining, if you will need to match the size of an exposed aggregate, etc. Consider your time. Time is money and production is key; the mock area should be large enough to set expectations for quality and price.

Make sure joints get vacuumed out because if there’s any silica dust, any grindings, shavings—anything loose—will need to be completely cleaned. Any loose material will prevent any repair product from achieving the appropriate bond. Your preparation before installing any type of repair is going to be key, says Demonte.

PREPARATION

How much to cut into the slab will depend on the width and depth of the crack. Every situation will be unique. In OPCMIA training sessions, Demonte says they suggest cutting

about 2-in. deep and then reassessing. Look at the edges of the saw cut. Will it need to be made wider? Are there imperfections?

“A lot of the times you’re turning an old warehouse into a polished floor area,” says Demonte. “They might have been running tow motors [or] pallet jacks, those wheels going over those joints tend to crack the edges even more.” The depth and width of the damage will help dictate what type of materials to use. Faster-setting concrete repair products and two-part epoxies tend to be more costly than regular joint fillers.

The size of the damage (or crack) relates to how you want to treat the area. For a hairline crack, Demonte explains that something roughly 1/8 of an inch wide or less, he suggests opening it up with tools like a nylon or soft wire wheel. For 1/8 of an inch or wider, his suggestion is to utilize an angle grinder with a U or V blade to open the crack up a bit; aim to go down about 1/2 to 3/4 of an inch.

The key here is to create a new surface for the repair product to bond while avoiding damaging any steel reinforcement within. Any bolts exposed should be trimmed to below the surface and chip the surrounding concrete away. Of course, treat any rebar corrosion.

Safety first, reminds Demonte. “Make sure that you’re wearing your proper PPE. Debris can be flying up. Make sure you have the safety glasses on. Make sure that you have gloves on. A lot of these wheels tend to explode and can do a lot of damage. Always make sure that you’re wearing the right protection,” he says. A mask or respirator may be needed.

• Utilize water to help with dust control

• Use a vacuum system with a HEPA filter to clean the crack and to help keep the air clean

• Make sure to have the right engineering controls

• Ensure grinders feature appropriate vacuum systems - whether your crack chasing or polishing

• Wear proper PPE

FILLER MATERIAL

Once cleaned, the crack will be ready for repair material. The OPCMIA offers a train-the-trainer class on concrete crack repair with experienced journeymen as instructors. While their repair training features Metzker

McGuire products, there are countless options for repair material on the market and some may behave differently than others based on concrete quality, even the freeze/ thaw cycle can be a major factor. Experience and time should lead you to “the sweet spot” when you find a product that works for you and your area. Be sure to read the label and manufacturer directions to use the right repair product for the situation at hand.

Be sure to know if you’re using a fastor slow-setting product. Noting “time is money,” Demonte prefers using a fastsetting repair material when possible. “If I’m waiting for those slower products to take place, I’m going to have to be really organized on how I’m attacking this floor area because I have to take that into consideration,” he says. Also, consider any necessary decorative requirements and if the repair product you’re using can be customizable to match the slab. Follow the manufacturer’s steps as needed. Color and stain matching any complex decorative elements may require additional time.

The application of the product depends on how large of an area is being treated. Many products can be applied using a cartridge gun. There are a variety of these tools available, some are designed for dual cartridges for convenient application of a two-part epoxy. Different repair product manufacturers may require purchasing their tool to install the product. A twocomponent joint filler pump may be needed for larger areas.

Demonte recommends filling the crack to the point to ensure adhesion; overflow it just a little bit. This may take a few applications. Once cured, return with a or grinder (handheld or walk-behind if the area is large enough to warrant) later and make it flush with the slab. “You don’t want a big mushroom cap over the width of the joint, you want it to be just enough so it covers the whole thing,” he advises.

The depth of the slab usually dictates how the depth of the crack. Since it’s likely safe to assume that the crack is going all the way through the slab come back once or twice with the repair material. If the crack does travel through the slab and depending on how fast the product sets, injected material can sometimes seep underneath the slab and fill any voids beneath.

Like their gas-powered counterparts, battery-powered machines thrive when they are well cared for. Here’s how to ensure that your lithium-ion powered equipment delivers optimal power and a long lifespan, maximizing its environmental and performance benefits for years to come.

CHARGING BEST PRACTICES

One of the most important aspects of lithium-ion battery care is charging. These batteries are sensitive to charge cycles, and improper charging can have a detrimental effect on their overall lifespan. Always use the charger provided by the manufacturer. These chargers are designed to meet the specific needs of your battery and prevent overcharging—a common culprit in battery degradation. Most modern chargers are designed to stop charging once the battery is full, but it’s a good practice to unplug the charger when the charging

PRO TIP: Look for a piece of equipment powered by a battery that is made with its own charging platform. This usually means there are special safeguards and features built-in to optimize charging and prevent the issues that can come with overcharging.

process is complete. This simple step can go a long way toward preserving the battery’s health.

It’s also important to note that lithium-ion batteries can be charged at any time, regardless of their charge level. Unlike other battery technologies, there is no need to fully discharge them before recharging. This flexibility allows more convenient use and helps maintain battery health.

STORAGE CONDITIONS MATTER

Storage conditions also play a vital role in the longevity of lithium-ion batteries. Extreme temperatures can have a significant impact on their performance and lifespan. When it’s not in use, store your batterypowered equipment and its battery in a cool, dry place, avoiding direct sunlight and areas prone to significant temperature fluctuations. This can help prevent irreversible damage to the

Just like with any piece of equipment, preventative maintenance is another crucial aspect of lithium-ion battery care. Periodically check your equipment and battery for any signs of damage, wear, or corrosion. Pay close attention to the battery contacts and terminals, gently cleaning them with a dry cloth to remove any dirt or debris that might hinder proper connection. Concrete worksites are especially likely to generate dust and debris, so this is especially important for battery-powered concrete equipment.

Unlike other battery technologies, lithium-ion batteries perform better when they are not deeply discharged. To maximize battery health and extend its lifespan, avoid completely draining the battery before plugging it back in. Most manufacturers recommend recharging the battery when it reaches around 20-30% capacity for optimal performance. Deeply discharging a

lithium-ion battery can cause it to lose capacity over time and reduce its ability to hold a charge. It’s best to keep the battery within a moderate charge range, avoiding both full discharge and continuous overcharging.

FOLLOWING THE MANUFACTURER’S LEAD

The manufacturer’s instructions are your best resource for ensuring the proper use and care of your equipment. Don’t push your equipment beyond its recommended capabilities. Overloading or exceeding its intended workload can put undue stress on the battery and shorten its lifespan. Regularly clean the equipment and remove any debris that might have built up. This helps the machine operate more efficiently and places less strain on the battery.

SOFTWARE UPDATES

In today’s digital age, some batterypowered equipment comes equipped with smart features and firmware updates. Keep your equipment’s software up to date to make sure it operates efficiently and to take advantage of any updates that may improve battery performance and overall functionality. Manufacturers often release updates that address potential issues, enhance battery management systems, and optimize power consumption.

SAFETY FIRST

As with all construction equipment, safety should always be a top priority. Follow the safety guidelines provided by the manufacturer, and if you suspect any issues with the battery, stop using the equipment immediately. Store the equipment away from flammable materials and follow proper disposal procedures if the battery needs replacement. As an operator, always wear proper protective gear when handling batteries or operating electrified equipment. With concrete work, operators are often working in dusty conditions and indoors. Battery-powered equipment has significantly changed the working conditions for crews and operators when it comes to noise, vibration, and overall comfort and safety on the jobsite.

By following these practices, you can ensure that your lithium-ion-powered concrete equipment delivers optimal performance and a long lifespan, minimizing your environmental impact while you tackle the task at hand. Battery power not only enhances the operator experience when it comes to comfort and safety but also contributes to a more sustainable and efficient jobsite.

Remember, a little care goes a long way in keeping the power and reliability of your equipment at peak performance.

QUALITY, SAFETY, PRODUCTIVITY & SUSTAINABILITY

HOW SAUNDERS CONSTRUCTION TOOK A PROGRESSIVE APPROACH TO PROJECT MANAGEMENT WITHIN THE ONE RIVER NORTH HIGH-RISE CONSTRUCTION PROJECT.

The distinctive One River North project, located in the River North neighborhood of Denver, is a highrise structure like no other in the city, and perhaps the world. The 343,000-sq.ft., 16-story building features an exterior rift that resembles a slot canyon that comprises over 13,000-sq.-ft. of water elements and landscaping.

For Saunders Construction, the project’s prime contractor, the impact of this clever design goes well beyond the aesthetic. This leading contractor, working closely with Trimble, has used this project to demonstrate and dramatically improve its concrete cast-in-place practices, with an increasingly advanced technique that involves pre-concrete pour scanning.

With this approach, the Saunders team realized enhanced project predictability and operating margins, reduced rework and material use/waste and better environmental outcomes for an ROI that is as eye-opening as the exterior walls of this impressive structure.

The ROI of the entire virtual design and construction process was estimated at 1,164% for this project, with a total project cost savings of $505,000 and a total CO2 savings of 144,221 kg.

COLLECT & CORRECT

Traditionally, post-tensioned concrete floors are subject to errors ranging from missing embeds, bollards, and planter drains to misplaced or misoriented connection conduits and lightboxes. Conventional quality control methods are typically slow and error-prone with long feedback loops.

Matthew Hamann, design phase manager at Saunders Construction, explains, “We have used scanning previously to quality check our work,

but the quickest we could turn around that data was two days and by then the concrete is poured, making rework more difficult, costly and potentially dangerous. Ideally, we wanted to scan the floors, check them against the models, and fix items before the pour.”

He and his team had been working with Trimble to facilitate a pre-concrete pour scanning workflow where one floor of the high-rise is scanned prior to the pour. That is compared with fully coordinated models and drawings to identify any issues—in the field and in minutes.

“We’ve tested and refined this workflow on other projects,” Hamann notes, “but wanted some clear evidence about the potential ROI for reduced rework and faster issue resolution before investing. We also wanted to see if teams that got very short-cycle feedback would rapidly learn to avoid most errors—and then how all of that improvement translates to carbon emissions.”

“Because this is a post-tensioned concrete structure, accurate and complete installation is essential. It’s difficult and dangerous to repair these types of decks.”

Matthew Hamann, Design Phase Manager, Saunders Construction

AUTOMATED & ACCURATE

The 16 above-grade floors, each measuring about 14,000 sq.-ft., along with underground parking, are built with relatively similar floorplates. However, the exposed concrete ceilings, floors, and other elements required very precise installation of all elements to meet specifications and architectural requirements.

Hamann adds, “Because this is a post-tensioned concrete structure, accurate and complete installation is essential. It’s difficult and dangerous to repair these types of decks.”

The MEP BIM coordination had already been completed, so locations of embeds, bollards, drains, and other assets had all been digitally located to within an eighth of an inch. Even junction boxes for light fixtures in the ceiling were located with that same accuracy.

Once the floor elements were installed, the Saunders team set up the Trimble X7 high-speed 3D laser scanner, which includes integrated high dynamic range imaging and survey-grade self-leveling capabilities on the floor. As well, the coordinated 3D model was uploaded onto a tablet using the Trimble FieldLink software and Trimble Connect Cloud.

Once the scanner was positioned to existing control points, scanning began. On average, five or six scans of each floor were conducted. Once completed with the scans, the FieldLink software was used to refine all of the scan geometry to ensure a few millimeters of precision. The complete floor scan was automatically overlaid on top of the 3D model where the operator then ran the Inspection Tool and set the tolerances to 1/8 in.

Subsequently, the operator could quickly see items highlighted in green that were in tolerance, and items highlighted orange to red that were out of tolerance. The field crews moved the items that were highlighted in orange and red to the correct locations prior to the concrete pour.

The entire process—from scan to visual evidence of errors—was less than an hour.

Beyond the immediate benefit to the construction workflow, Saunders extrapolated its findings from the initial pours across the whole building to calculate aggregate impacts for the whole project.

OPERATIONAL IMPROVEMENT

The classification of issues enabled the Saunders team to make detailed estimates of the likely labor requirements by discipline, equipment needs—and therefore their power requirements—and the materials needed to rectify issues. The result was a multi-dimensional data set that could be analyzed for additional insights over time.

The results have led to a robust understanding by Saunders about the impact of each type of issue, which is categorized as either minimal, moderate or high impact. For instance, missing ramp embeds were classified as a 1 (high) in severity where an electrical sleeve misplacement might be a 4 (minimal). However, even a minimal effort correction in the field could have cost the project over $3,000 when all of the various stakeholders from the field foreman, project management, architects, and other team members were

included in the process. A medium to high-impact issue could run from $7,000 to $25,000 or more.

While issues still occurred after pre-concrete pour scanning was introduced, the severity of issues was low and the frequency of issues decreased markedly as the project progressed to the higher floors.

Hamann adds, “Essentially, the ability to rapidly find and fix problems helped teams learn faster.”

The contractors and subcontractors learned from their errors/omissions on the first few floors and largely avoided missing any items after that. They also progressively reduced the number of misplaced items on each following floor.

The Trimble Saunders team further calculated the overall impact of each issue in terms of labor, equipment use and materials—and the amount of carbon based upon Saundersvalidated estimates for labor, equipment and materials. For instance, the resolution of a missing sleeve or J-box location is largely labor with some equipment, so the carbon emissions are relatively small. However, resolving a missing embed, while still largely labor, requires more equipment, materials and power, approximately doubling the carbon impact as compared to a missing sleeve. A missing bollard nearly doubles those numbers again. That data was extrapolated across the entire building.

On this project, the benefit of pre-concrete pour scanning resulted in an approximately 39% reduction in the costs of errors and their associated impacts, together with an approximately 31% reduction in embodied carbon associated with fixing issues just to the cast-in-place floors.

The ROI of the entire virtual design and construction process was estimated at 1,164% for this project, with a total project cost savings of $505,000 and a total CO2 savings of 144,221 kg.

BEYOND ONE BUILD

For Saunders, the study showed that the fast, field-based pre-concrete pour scanning workflow can substantially reduce rework on construction projects, leading to improvements in cost, predictability, waste and substantial carbon emission reductions.

In addition to the quantitative benefits, the intangible benefits included improved project predictability and the reduction of work, which is known to correlate with a reduction in accidents, thereby increasing the safety of the workers.

“Rework continues to be a leading precursor for injuries in the construction industry,” says safety director Justin Tourdot. Utilizing the latest scanning technologies on this project resulted in reduced errors and rework, which is ultimately safer for all workers.”

Hamann concludes, “Having real time point cloud data overlaid with our fully

coordinated signed off models in our project teams hands in under one hour is extremely valuable and allows our team to take a proactive approach to resolving potential issues before the concrete pour. Unplanned rework is costly, demoralizing, time intensive and can be dangerous. The workflow we have proven out with the Trimble X7 laser scanner and FieldLink software to do infield comparisons helps ensure we are building things right the first time.”

THE SAVINGS WITH TIRE MONITORING TECH

With a flat potentially running a batch of concrete, here’s how Ernst Concrete found savings and increased services with a tire monitoring system.

Summer is tough on tires, especially when those tires are hauling a heavy load, like those on the Terex front discharge mixers that Ernst Concrete uses. When empty their mixers weigh in at 33,500 lbs.—when loaded they tip the scale at closer to 70,000 lbs. Tires that were properly inflated that morning can pick up debris on the construction site and lose air throughout the day. Run flats were causing headaches for Fleet Manager Mike Jones.

In addition to the schedule disruptions and delays caused by roadside tire service, there is the potential to ruin a fresh batch of concrete, and the out-ofpocket costs. A tire monitoring program is helping to eliminate the run flats and all of the problems associated with them, saving Ernst time and money, while improving their service.

Ernst Concrete operates roughly 350 front and rear discharge mixers from their 43 locations across Ohio, Indiana, Kentucky, and Georgia. They’ve been in business for over 75 years, so dealing with summer heat and its issues is nothing new to them.

“The biggest issue we were having was run flat issues,” recalls Jones. “Drivers would run on low tires, and when we changed out those tires or when we turned them in for credit they would be junked because the cords inside were broken.”

With the cost of a new tire close to $1,000, and casing credit of $200, every trashed tire was costing Ernst $1,200. Jones suggested that they try a tire monitoring system by Doran in a single Kentucky location.

“When we put the system in, we went from seven run flats to zero. As many tires as we go through a year, that was a huge savings for us,” says Jones

Armed with these figures, Jones approached upper management with the idea of rolling it out fleetwide. The

initial decision was to let each location general manager decide whether to implement it or not. A few decided to, and the results were impressive enough to warrant implementation across the whole company.

“External, valve stem-mounted sensors pass tire pressure and temperature data to the in-cab monitor/display, providing drivers with real-time information and alerts.

Doran 360 tire monitoring systems include visual and audible alerts for low inflation pressure, rapid deflation events and high tire temperatures. Drivers can see which tire is impacted and exactly what is going on with it.”

Ernst Concrete

In addition to eliminating run flats, and saving those associated costs, Jones credits the system with shortening their response time to incidents. “It’s a proactive system. Instead of waiting for the tire to go down completely, and then pull over, drivers can alert maintenance that a tire is going down,” says Jones. “If we can’t get to them right away, we automatically dispatch a tire company to them. The response time has decreased a lot because we know what’s going on.”

HOW IT WORKS

Monitoring temperature is important, because even if a tire is fine, but a brake is sticking or a wheel bearing is going bad causing the temperatures to rise, the system will alert the driver. This is important because the belts inside a tire can separate from the rubber at around 200° F, creating a safety issue for unsuspecting drivers and those in their vicinity. The tire monitoring system monitors tire pressure and temperatures on all connected tires, then alerts drivers when tire temperatures reach 175° F. If a tire reaches that temperature, the driver will receive a visual and audible warning on the in-cab display which then allows them to find a safe place to pull over and lets

their tires cool off and avoid a catastrophic event.

Monitoring tire temps is paying dividends off the road too. In addition to installing the system on all the company’s mixers, they also installed them on the loaders they use in the yard. They typically use either a Cat 950 or a Komatsu 380-8, both 3 1/2-yard loaders.

“When they’re working in the yard, they dig into the piles, then back out and turn to offload,” says Jones. Stooping into the piles can raise tire temps. “We were seeing elevated temperatures in the loaders, especially the left rear loader tires. The operators adjust how they attack the pile, and we’re seeing a lot less tire wear.”

That is another substantial cost savings opportunity because the tires cost $2,300 to $2,500 a tire. “That’s a huge savings if we can extend the life of that tire,” says Jones.

Maintaining proper mixer tire inflation pressure maximizes the performance of the tire, leading to reduced downtime while improving safety and efficiency. Designed to handle the extreme environmental conditions found on roadways and construction sites across the nation, tire monitoring systems like that from Doran account for heat, vibration, and the longevity needed for performance on the open road.

Jones attested to the ease of installation, saying “Most of our shops are

one man deep, and they can do it by themselves. For the most part its simple to install, the longest part is calibration.”

Initial installation may take two hours or so, but technicians can typically accomplish an install in an hour to an hour and a half per ready-mix vehicle.

Monitoring and continually reporting tire pressures and temperatures allows Ernst drivers to communicate with the maintenance teams to schedule repairs and corrections. That is shortening service call response times and improving their customer service. Proactively monitoring tire inflation pressures helps to reduce tire-related maintenance costs, extend tread life, protect casings, and minimize catastrophic tire failures.

WHAT’S EVEN BETTER THAN SIMPLE INSTALLATION?

No installation. When Ernst Concrete officials met with the Terex team to discuss future orders, the concrete supplier showed them the Doran system and asked if something like that could be integrated into new mixer deliveries. Terex officials were intrigued with the idea and began discussions. As of October 2023, all new Terex front discharge mixers include the Doran 360 system as a standard option.

IGNORANCE COSTS MORE THAN EDUCATION

Educating our new workers may be the biggest effort we can make as owners and leaders. With a growing number of soon to be retired workers, contractors must consider their options.

Educating our new workers may be the biggest effort we can make as owners and leaders.

With a growing number of soon to be retired workers, contractors must consider their options: A. Seek out more of the already trained and experienced… at an all too high starting wage OR, B., recruit and hire a less trained worker in our industry and then dedicate the needed time to get the new workers “fast-tracked” on training.

Yet, for many contractors, who are in the business to execute work, taking the extra time to spend educating new workers with no history in our industry, the cost to train may be expensive and time consuming.

I remember a car bumper sticker years ago that read, “If you think education is expensive, try ignorance.” Boy does that sentiment hit right in the “kisser.” So, what is a contractor to do? From my perspective of observing companies and consulting with contractors for more than thirty-five years, my money is on education. Let me give you three simple tips to implementing education in your company in 2024.

• Create your own training films. Sounds crazy? Consider shooting short videos from your smartphone. Seriously! Most of the new and

younger workforce are more comfortable watching their favorite YouTube videos from their phone. So, begin recording how you want to see a truck loaded, or how to safely tie-down equipment, or…you get the idea. Keep the video’s to 3-5 minutes in length and then download an app that helps you to do “voice over” for the video, thus providing the proper training words you want shared. A contractor taking this route will have dozens of beginning training videos for the newbies, adding to their visualizing what and how we do things.

• Create your “WHY” about doing what you do. Most employees will achieve confidence in the contractor they are employed by if the company can explain WHY they do what they do. Sure, it’s to meet the customer’s needs but it is also to provide a good living for workers, to keep people growing in their knowledge about work, people, processes, etc. But it is also to help the contractor to build a business that is respected by all, employees, customers, and suppliers. Sharing your WHY can answer a lot of questions for a new worker.

• Create a mindset in your company to see every opportunity as a learning moment and every worker as worth being either a teacher or “student.”

If you, as the owner or senior leader, embrace a work culture where we are learning from one another and learning from mistakes along the way, the people in your company will step up and feel like they are a part of a special organization, as so many companies are stilling failing miserably in educating their workers.

Obviously, there are several items that can support each of the above points but consider this fact. Most employees are almost screaming out that if they are not spoken to when first hired, if they are trained almost starting on day one, and if they are receiving no follow-up or coaching, their time with that type of company will be less than sixty to ninety days. When our industry is already fighting for respect from school educators, who seem to continue to push students into the college direction, we need to take some extra steps to win over a whole new generation of workers, they are most often called “Gen Z’s” or “the Centennials,” to our industry where they can find both satisfaction and financial stability.

Add training your new works, from day one, and you will find this year to be the start of some very good growing and profitable years ahead!
