EDITOR’S LETTER

Productivity & Battery Power Reigned at World of Concrete

EDITORIAL Editor .......................................................Jonathan Kozlowski jkozlowski@iron.markets Managing Editor .................................................. Gigi Wood gwood@iron.markets

T

hey can increase efficiency. They can integrate some of the most innovative ideas this side of green concrete.

They can redesign systems to be safer, more userfriendly, decrease the working noise, etc. For me, all I saw JONATHAN KOZLOWSKI, when walking the halls of World of Concrete was productivity.

EDITOR JKOZLOWSKI@IRON. Productivity not only for the contractor but from the work the MARKETS manufacturers and exhibitors put in throughout the year(s).

True, one would have been able to find new tools and equipment to help the construction professional be more productive at every show, but the industry has been slowly pulling away from the pandemic years. Allow me a bit to walk through my week and attempt to explain why I think a “productive” World of Concrete is important for the construction industry.

This year’s show marked the its 50-year anniversary. Join us in celebrating year 51, World of Concrete 2025 is scheduled for January 21-23 in the Las Vegas Convention Center with educational sessions starting on January 20.

This year hosted nearly 60,000 registered construction professionals. According to the show runners, that’s a 23% increase in attendance from the year prior. Anecdotally, people were saying that the numbers felt like “pre-COVID.” Economically, this points to a good sign. I sat down with Dodge Construction Network, chief economist Richard Branch. On top of their forecast, it seems to allude that not only are contractors like yourself out there eager to reconnect with fellow pros, but very interested in looking at more products and equipment to increase efficiency—or be as productive as they can.

A team from Wisconsin won the SPEC MIX BRICKLAYER 500 Championship for the second year in a row. Michael Schlund and tender Aaron Kowalski laid 752 bricks in one hour.

They took home a trophy, cash, and a brand-new Chevrolet Truck.

The ever-increasingly successful Concrete Industry Management auction raised $1.8 million for their program providing funding for concrete industry management programs in Chico State, Middle Tennessee, New Jersey’s Science and Technology, Texas State, and South Dakota State.

Donated auction items included a concrete mixer truck from Mack Trucks Inc. and Revolution Concrete Mixers, a Peterbilt & ConTech mixer truck, a concrete pumper donated by Alliance concrete Pumps & Pape Kenworth, and many others.

If lucky enough to walk by during the ceremony, attendees were even able to see a marriage in front of the WOC logo installation in the grand entrance of the Center. A celebrity minister

from Las Vegas officiated the wedding of Patricia and James Estrada on January 24 at noon.

Quoted in the official announcement, James says, “I’ve been married to concrete for 30 years, so it was finally time I married Patricia. It felt like the right moment and right place to share the blessings my career has provided.” If you’re readers or not, congrats you two.

Read more on some World of Concrete happenings on page 18 in this issue.

That’s enough from me. Until next time, stay safe out there.

Floors & Flatwork: Burn The Edge How an innovative tool allowed the concrete professionals at Phaze Concrete to produce high quality edge results.

8 CONCRETE CONTRACTOR MARCH/APRIL 2024

O

ne of the more challenging aspects of working on a larger slab project like a grocery store is matching the edging of a new placement to the existing slabs. A ride-on machine can weigh upwards around 2,600 lbs. which limits how close an operator can get to the edge. While there may be 50 ways to finish edges, a keen eye brought a non-traditional method to the job—without going manual.

John Beagley founded John Beagley & Sons roughly 30 years ago along with a handful of 8 people including his 16-year-old nephew, Leroy Johnson—who now sits as vice president of operations. Much like many contractors do when they start, they began with residential projects. In the early 2000 they became certified as a Walmart finisher for new stores. From there-on, they grew.

After changing the company name to Phaze Concrete in 2009, that small company has grown to over 400 employees. The company covers a massive territory—everything west of the Mississippi, with offices in Montana, Denver, and headquarters in Cedar City, Utah.

“What stands us apart is we’re always cutting edge,” says Johnson.

Their niche is working on the larger slabs, buildings over 1 million sq. ft., parking structures, tilt-up construction, and more. The company has a significant presence in the ACI community, Johnson himself sits on a couple of ACI boards (360 and 380), the owner sits on a handful of committees like 317, 304, 303.60 as well as a number of ASTM groups. Over the years, they’ve won several awards from SSI. What can only be a testament to the quality of their work, they’ve also never advertised. Impressively, their growth has been mainly from word of mouth.

Another unique feature of the company, Phaze also uses a fully accredited four-year mentorship program providing students education on basic CAD designs, estimating skills, managerial skills, and more. The program has been a powerful tool. “One of the things we do is make sure [the students] graduate with a GED…and an on-site work ethic that most people don’t have,” adds Johnson. On average, they take on 12 to 20 students a year. They had 8 in 2023. According to Johnson, roughly half go on to start their own businesses or work elsewhere. In fact, Johnson’s son and daughter went through the Phaze student program. His son is now a superintendent running a team. His daughter draws CAD and conducts estimates.

In a way, the mentorship addresses the skilled labor shortage. Many of the students continue afterward and work for other companies. The goal is improvement. Johnson explains that the owner’s goal is that if someone has a better offer or a way of bettering their life, he feels like he’s been successful. Adding that, “he encourages every person to better their circumstances as they can.”

AN OPEN SLAB Phaze was hired for a new build project for CostCo—a client with high standards for their concrete. This standard required them to burn the edge of the concrete placed to match the rest of the slab with FF / FL specs at 40/35 using 4,000 psi concrete supplied by Knife River.

“It’s always a challenge,” says Johson.

While you can finish most of the slab with a 2,600 lb. ride-on machine–except for the edges. Roughly about 6-8 in. from the joint gets black from the weight of the machine. The trick here at the edge

www.ForConstructionPros.com/Concrete

is ensure the edge is blended to the rest of the concrete and the neighboring slab, which makes the joints stand out.

Offering it up as some friendly advice, Johnson explains, “When your lights are on, and you see a nice slab right up to the cold joint and you have 8 in. on one side that’s not black, that’s the challenge.

They all hate it…all the grocery stores that we pour that have finished slabs—that is one of their biggest pet peeves.” While Phaze was successful for years using walk-behind; it takes time and a skilled finisher.

For the CostCo job, Phaze had 26 workers on the project with 13 each on the finishing and laying out teams. Work started at 2 a.m. in the morning with each pour working a 20,000 sq.ft. (roughly) 6-in. deck. The schedule was placement from 2 to 7 a.m., finish until noon, and then saw cutting from noon to 6 or 7 p.m.

As packed as the schedule may have been, timing is (and will forever be) everything.

As an open-air slab, a portion of the building was constructed which placed some of the concrete exposed to the sun—creating yet one more challenge to finishing process. As Johnson explains, sun and/ or shadows on a slab can slow down the hydration of the concrete and pushing different set times. Shadowed areas can leave a dark streak in the concrete. “It can make it hard to burn off (also known as ‘blackening’) because you don’t get a consistent burn on the top of the surface,” explains Johnson.

They followed their standard process. After screeding, taking a straight edge, then float it twice until the initial set starts. After, they finish 12 in. away because the ride-on pans can finish that close.

While this process is going on, they’ll run pans, clean up machines, and burners alongside a 3 ft. walk-behind to blend.

It’s this last step where they opted to change tools. Having experimented with the tool on smaller pours previously, this was first large project Johnson brought a Kipper 11.5 to help blend the edge. As Johnson explains it, they were able to use the tool for that 12-in. area and worked right up to the edge with half the work. “It was easy to control with little bit of water and finish it right up to the edge,” he says.

He adds that with the tool, “You have quite a bit of a window to finish, but with a 2-ft. machine if you get on it too wet, it leaves trowel marks.

With this little Kipper you just lift up on it a little bit, feather it in and come back when it’s a little more ready.”

Blackening the concrete happens when a metal blade darkens the surface. If the process isn’t done just right, the surface will remain a lighter tan and end up spotty. The variation between black and dark gray will cause your edging to look un-uniformed.

Before blending on the CostCo project, Johnson experimented with the Kipper 11.5 elsewhere. One for some trench drains where he gave the tool to his son to work around the drains of a 200,000 sq.ft. building, creating a ton of piping and a pain to finish. While not necessary to burn the edges at that time, they wanted to put the tool to the test. Knowing the need to burn the edge and proper blending will be vital to the customer, the results convinced him to bring it to other jobs.

Ultimately, there’s a sense of optimistic productivity with the tool as it helps nearly anyone to produce proficient work. “The bright spot of it is there is a way to get those edges to look a little nicer,” Johnson says. “To give your client a better product without having to have as high a skill set as you normally would have to do to get that perfect. I can take a guy that’s a pretty good finisher, [but] that I would never put on those edges, give them 20 minutes of education, let them go and make those edges look like a professional.”

A

s the first-place winner in the American Concrete Institute’s (ACI) 2023 Excellence in Concrete Construction Awards/ Decorative Concrete Category, the Torguson Park skatepark demonstrates concrete’s potential for visual appeal and much more. Opened in 2021 in North Bend, Washington, the cast-in-place concrete facility meets high standards for safety, requires little maintenance and provides a fun and challenging environment for its users. The old 6,000 sq.-ft., single-bowl-style facility was replaced with one nearly 13,000 sq.ft.

14 CONCRETE CONTRACTOR MARCH/APRIL 2024

GRINDLINE The park was built by Grindline Skateparks Inc., a Seattle-based skatepark construction company. The Grindline team is comprised of former professional skateboarders turned concrete craftsmen, which puts them in touch with the needs of their parks’ users. Grindline worked with the community to gather input for the new design and began construction in 2020, staying on schedule even during the COVID-19 pandemic.

Ready-mixed concrete allowed the team to design and build any shapes

they desired. The earthy color palette of the concrete, achieved using integral color, was inspired by nearby Mt. Si, which can be seen from the facility. The skatepark was constructed using the shotcrete method, which helped achieve the smooth-flowing transitions and curves of the design.

“The complexities associated with building a skatepark don’t have to do with its structural system, as people sometimes assume,” says James Klinedinst, the senior project manager for Grindline. “Skateparks are non-structural slabs-on-grade—a

FLATWORK/SLAB CONTINUED very familiar type of construction. We use earthwork to provide the shape and support of the concrete skating surface. The complexities have to do with making the surface smoother than what is required by many other types of concrete construction.”

When constructing a new skatepark, earth is shaped and then formwork is installed. “The formwork used for skateparks is unique compared to other types of concrete construction,” says Matt Fluegge, chief executive officer for Grindline. “We don’t use panels, since every part of a skatepark is geometrically unique. We custom fabricate radii out of plywood and board lumber.”

After formwork is in place, concrete is installed, 6-in. thick in areas requiring the shotcrete method, and 5-in. thick in the conventionally placed slab areas.

As with all concrete construction, crews must make sure they are using installation methods that will prevent

16 CONCRETE CONTRACTOR MARCH/APRIL 2024

cracking. Since wide expansion joints containing joint filler would create too much roughness on the skating surface, the team ensures smoothness first by sequencing pours in such a way as to create seams in locations that might be prone to cracking, and second by saw-cutting 1/4 in. control joints in the remaining critical locations.

Finishing methods are also important. “We hand trowel an airentrained mix, which is not standard,” says Klinedinst. “Typically, air-entrained mixtures are broomed or textured. It requires a technique learned over years to hand-trowel in a way that releases the trapped air and prevents delamination.”

Having consistency in the concrete mix is also critical. “We’ve used a tried and true, off-the-shelf shotcrete mix from Heidelberg Materials for years. And while we have that single, preferred mix, because we build parks all over the country, we also have to

take into consideration variations due to regionally available aggregates and other local materials,” says Klinedinst. “We address this by sending our suppliers a cut sheet that breaks down aggregates and other mix contents.” The concrete mix included Heidelberg Materials’ EcoCemPLC portland limestone cement, which lowers the carbon footprint by about 10%.

CONNECTING SKATERS WITH CONCRETE JOBS The Grindline team is not the only organization to discover that skateboarders and concrete are a natural fit. A program called Skate4Concrete points passionate skateboarders who are looking to build their careers toward industry opportunities.“Whether an individual is college-bound or not, there’s a way to make a mark on the skateboarding community and play a bigger role in the sport. Skate4Concrete

www.ForConstructionPros.com/Concrete

shares information on concrete construction and supply jobs, along with information on certification. It even connects skaters with details on degree programs,” says Crystal Howard, founder of Project Cornerstone and Skate4Concrete.

Corey Rosson, senior sales representative, Pacific Northwest Heidelberg Materials, works in the building materials industry but has been a skateboarder since he was 10 years old. Rosson became aware of Skate4Concrete when Heidelberg Materials North America mentioned the program on social media channels. “It’s exciting to see Skate4Concrete offering a different approach to career development. Often, three main routes come to mind for young people coming out of high school: college, trade school or the military. Having an additional pathway that connects people to work—work that’s built around something they already love—is a real benefit,” says Rosson.

A major initiative of Skate4Concrete is an internship program that had its first student

intern in the summer of 2023. Interns spend three months being part of a building team for a skatepark and, one day a week, gain exposure to various aspects of the concrete industry by touring facilities such as concrete and/or cement plants and quarries. They also spend time with city officials who are managing the skatepark construction project.

As a joint effort between Skate4Concrete, California State University Chico and skatepark designers, it is currently available only to Concrete Industry Management program students.

“Nominated from our Washington Excellence in Concrete Construction awards program, Torguson Park competed and won at the highest level of concrete competition: ACI’s International Excellence in Concrete Construction awards program. This recognition has opened doors for our industry locally as we conduct tours and meet with officials to present them with their awards.

ACPA’S PUSH FOR SUSTAINABLE INFRASTRUCTURE The American Concrete Pavement Association announced its new responsibility to help make roads and buildings more sustainable, including: • Release of a report titled, “How Agencies can Reduce Costs by Improving the Competitiveness of their Bid Environments.” The report details industry research, including research performed by the MIT Concrete Sustainability Hub (CSHub) that examines how the split of Department of Transportation (DOT) paving expenditures between industries impacts paving unit costs. Findings include the fact that, as inter-industry competition increases, unit costs of both concrete and asphalt paving materials fall significantly—particularly those of concrete. For example, if a state with a low concrete market share (e.g., 1%) were to increase its concrete market share to 25%, it would lower concrete and asphalt paving material unit costs by around 29% and 8%, respectively. The ACPA report also includes recommendations on how to start a competitive paving program.

• ACPA’s participation in the Reduced-Carbon Concrete Consortium (RC3). The RC3 will disseminate funding information, facilitate application submission, provide technical assistance, and enhance contractor preparedness with critical next steps like Environmental Product Declarations (EPDs).

• A growing library of long-life pavement case studies. .

The press conference also covered the International Grooving & Grinding Association’s white paper titled “Diamond Grinding: A Safe, Sustainable, Quiet and Cost-Effective Solution to Better Roadways.” The IGGA is affiliated with the ACPA in a partnership known as the IGGA/ACPA Concrete Pavement Preservation Partnership. https://CONC.me/hy8dhnmk

WHO RECEIVED A 2023 GOLDEN TROWEL AWARD?

By Jeff Rogers, director of engineering at The Face Companies The Golden Trowel has been presented for 35 years to contractors who produce the world’s flattest and most level floors. They are awarded in several different categories, based on how the floor was initially struck off, how wide the floor castings are, how much shakeon hardener or steel fibers were used, and other factors that influence flatness and levelness. Golden Trowel Gold Plates are awarded to the winner in each category, while Golden Trowel Silver Plates recognize truly outstanding entries that achieved exceptional results but did not dominate the category.

The best floor in the world back in 1990 wouldn’t even be considered for a Golden Trowel today. Of the 12 Gold and Silver Trowels awarded during this year’s World of Concrete, 10 were from Brazil, China, and Thailand, and only 2 were from the USA. https://CONC.me/54tnegjm

HOW TO BY JONATHAN KOZLOWSKI,EDITOR

Getting Started with Super Flat & Level Floors The first step in super-flat floor work is recognizing the skill required.

Let’s go over the elements involved.

B

e in guidelines or requirements, all details of what a job requires should be found within the scope of work. When there’s a specification on the floor flatness (FF) and floor levelness (FL), Concrete Contractor spoke with Nick Demonte, ITF cement mason coordinator from the OPCMIA to find out how one begin working toward achieving those higher numbers.

To start, the biggest criteria is understanding the concepts involved. OPCMIA trainings start with a demonstration of determining the tolerance of a slab by using 10 ft. straight edge. While

this straight edge does not correlate to the FF numbers, it provides a visual effect of the tolerances of the end goal.

Demonte explains. “If you put a 10 ft. straight edge on the floor, if it teeter-totters in the middle, you know that obviously you have a bump in the middle. That tolerance could be an eighth of an inch, it could be a quarter of an inch, it could be a half of an inch.

That’s how the gauge the floor flatness.”

While there may be some nuances, put simply the higher the FF, the flatter the floor. If attempting to achieve an FF 25 (a quarter of an inch depth over 10 ft.)

one should be able achieve that by a regular straight edge methods with a bull float. Higher numbers like FF 50 would allow an eighth of an inch over 10 ft., and FF 100 would be a 16th of an inch over 10 ft.

At least that’s how it was once done.

Today, contractors have some more modern types of measuring devices to use. For one, the Dipstick Profiler from Face Companies developed by Allen Face. Contractors can also use an inclinometer to measure the floor and produce a profiler graph, or utilize a 3D scanner.

HOW TO CONTINUED The introduction to the 3D scanner to this process helps contractors respond more proactively to the situation. “Prior to the 3D scanner, the only way you could measure the floor was after you had poured it,” says Demonte. “After you poured it, and you finished it, you got 72 hours to measure the floor within that timeframe. But using a 3D scanner and how technology has improved, we can hook the 3D scanner up and get a scan of that slab within seconds of all different types of points.”

With this technology, contractors would be able to recognize if an area was too high and correct it on-site as they’re pouring as opposed to later and grinding the areas down or filling them.

“That’s going to help production if we don’t have to come back and treat the slab in any kind of way…because these tolerances are hard to achieve it takes a special skill set to do that.

It starts from the formwork and so on down the road – there are a lot of variables that move in there. Training is the biggest key to putting down super flat floors—training your eye to the finer details.”

One of the biggest keys here is recognizing the skill needed to ride a ride-on trowel machine: how and when to get it on the floor, when and why to use pans instead of floats, as well as gauging the angle of the blades.

CRITICAL DETAILS • Forming

24 CONCRETE CONTRACTOR MARCH/APRIL 2024

• How you pour the concrete • The equipment used to finish; consider the setup and finetuning of the laser-guided screed; the patterns from the ride-on trowel machine and how they’re going to cross; the direction used with a vibrating screed vs bump cutter Polishing is another matter completely. If the floor will need to be polished, it’s important to consider the relationship between the finish and FF value. For example, depending on the finish some polish classes may need a certain tolerance.

Demonte explains that many of the seminars they produce goes through the importance of trying to achieve those FF numbers when delivering a polished finish.

Timing and know-how is essential. Plan and keep track of the order of pours while noting shady vs areas more exposed to the sun. “There are a lot of moving parts about super flat floors. It’s not something that a contractor just takes on to try and see if they can get into this work,” says Demonte. “The best way to start—the easiest way to start is…reach out to your local [union].”

He recommends contractors is to do a little homework. The finishing industry has been working to make the language more universal so that the classification and levels of gloss are more coordinated. Part of that homework is also communication and being involved. If you’re the polisher for a job, attend the pre-conference meeting so you know what mix is used, how the floor will be finished—all the important details to achieve a quality floor.

Monolithic Concrete Pours Drive Efficiency For Concrete Contractors How monolithic concrete placements can drive efficiency for today’s contractors.

T

hroughout history, many new processes have come along to improve how people achieve end results. These innovations— even those that eliminate just one step—often lead to dramatic increases in productivity and efficiency. In an ever-evolving industry, contractors innovate through the equipment they purchase and processes they adopt. When it comes to concrete, monolithic pours are one process that contractors can use to drive efficiency.

Monolithic pours streamline concrete work by pouring curb and gutter simultaneously with flatwork, instead of completing these pours one at a time. If completed with the right equipment and considerations, contractors can reap the benefits without sacrificing quality.

SAVINGS A traditional pour most often requires curb and gutter work to be poured, finished and cured to outline the pavement area. Then, the crew returns at another time to pour and complete the flatwork.

A monolithic pour, or an all-in-one pour, improves efficiency by completing curb and gutter at the same time as flatwork.

This process saves a considerable amount of time by completing the entire job with one pour instead of two, boosting productivity and the bottom line.

Driven to continually seek new ways

26 CONCRETE CONTRACTOR MARCH/APRIL 2024

The monolithic pour process allows contractors to improve efficiency by completing flatwork and shaping the curb and gutter at the same time.

to keep up with ever-growing demand, more contractors are seeing the benefits of monolithic pours, especially for parking lots and streets. Contractors who streamline the most time-consuming aspects, such as hand-shaping curb and gutter, experience the most significant spike in efficiency and often double production. Just as the digital camera created a more productive photo development process, monolithic pours drive up efficiency for contractors.

PROGRESS With a good crew, walk-behind curbing machines are capable to maintain the production pace found with a laser screed while eliminating the extreme physical labor and the need for large machinery for curbs. These machines consist of a handle attached to a metal drum that is connected to a hydraulic power source. The single-operator machine reduces the intensive manual labor of shaping curb and gutter while producing a consistent, high-quality result, even for operators with minimal experience. While these machines were originally developed for completing curb and gutter work on traditional pours, most can be modified to adapt them for use during monolithic pours.

Newer entries to this class of equipment incorporate battery power and a

design specifically created for monolithic pours. These machines combine the benefits of traditional walk-behind curbing equipment with lightweight portability to quickly move throughout the jobsite.

Battery-powered walk-behind curbing machines offer easy maneuverability and transport due to their relatively small size and lack of cords and hoses.

Consider a contractor who was hired to install a large parking lot for a private company. The crew used a laser screed due to the sheer size of the project. They worked during the night to limit traffic interference and were able to pour about 2,000 yards of concrete pavement per night. However, they were only able to shape about 300-400 feet per night by hand. Investment in a battery-powered walk-behind curbing machine doubled that productivity to 700 linear feet per shift.

RESULTS Laser screeds and walk-behind curbing machines are ideal for projects such as parking lots with large amounts of flatwork and multiple areas of curb throughout. However, a machine that can shape curb and gutter simultaneously with flatwork can be ideal for certain

www.ForConstructionPros.com/Concrete

Walk-behind curbing machines with monolithic kits and batteryoperated walk-behind curbing machines are two options that contractors may consider for a more streamlined process of handshaping curbs.

monolithic pour applications like street construction or replacement.

Slipform machines are one of the more efficient solutions if and when the project matches the machine design parameters and there’s enough volume of concrete to justify their operation and overhead costs.

Some manufacturers offer custom drum options for hydraulic screeds.

These drums can reach up to 16-ft. long and can be designed to match a specific shape, like half of a street, including the curb and gutter. Custom drums replace the pipe on a hydraulic roller screed and use a spinning motion to shape the concrete.

This monolithic pour method is ideal for streets due to the long stretches of pavement that are the same shape. It is especially convenient for replacing existing streets because it allows one lane of traffic to remain open. After the crew completes one side of the street and it’s ready for use, they change the traffic flow to complete the second side.

In the past, this was only possible with large, expensive slipform pavers or through manual labor, but a custom drum with a hydraulic screed provides a method to complete the work for a fraction of the cost or time.

QUALITY A common misconception is that monolithic pours produce lowquality curb work. This may be true if a crew that is primarily focused on flatwork is hand shaping the curb. They may have little experience in curb and gutter work, and they have to apply most of their focus to the flatwork, which is the larger portion of the job.

However, the proper equipment can provide a key advantage and increase-all around quality to a monolithic pour. Replacing manual curb work with one of these mechanized systems makes it easy to achieve consistent, spec matching results, even with an inexperienced crew. The equipment is user friendly and enables contractors to accomplish more with less labor, a key advantage in a difficult employment environment.

WEATHER A key consideration when determining whether a monolithic pour is the right solution is the weather. Monolithic pours really shine in tough weather conditions. As seasoned concrete workers know, the weather dictates when and how efficiently they can pour. Dealing with a small pour window becomes less of an issue with a smaller number of pours.

www.ForConstructionPros.com/Concrete

For some monolithic concrete pours, contractors may benefit from using one machine to shape the curb and gutter as well as the flatwork simultaneously. This capability comes in the form of a custom drum with a hydraulic screed.

With the right equipment, monolithic pours can double or even triple production and help crews maximize the work they can complete before that window closes.

Despite all the advantages, there are some cases where a monolithic pour is not the best solution. These situations will come into play in colder climates. If a job uses asphalt for the pavement, the concrete curb and gutter must be poured separately. Additionally, the monolithic pour method is not ideal if the curb and gutter or flatwork may need to be replaced separately. In colder regions where brine regularly collects in the gutter, the freeze and thaw breaks down the concrete and leads to a shorter life for the curb and gutter than the pavement.

DEMANDS Contractors can maximize their investment in concrete equipment by purchasing machines that increase productivity for a variety of applications. Beyond custom drums for monolithic pours, hydraulic screeds also pair with standard pipes to screed flatwork for jobs such as streets and sidewalks. Walk-behind curbing machines have multiple drum options and can also complete curb and gutter for traditional pours. Additionally, battery-powered walk-behind curbing machines effectively complete patch and repair work and complement slipform machines to complete corners and tight radii.

The demands of the construction industry are shifting rapidly. There is a high demand for work, and contractors can capitalize on these opportunities by finding innovative solutions that improve their processes and increase their capacity.

Monolithic pours are not the answer for every concrete project, just as instant cameras and rakes are still used instead of digital cameras and mowers with baggers. But with the right equipment and the right application, a monolithic pour may be what drives an operation to peak efficiency.

their intent to teach safe practices?

• Do you have clear and visible signage in your shop, yard, and especially on each jobsite?

• Do you have informative “5-S Maps” that indicate where everything is kept on trucks, trailers, your shop, and yard?

• Keep ample supply of barricades, flare tape, emergency kits, safety vests, tie-offs, and just about every other “safety tool” that can help prevent any issues.

prime aspect of “risk management” is the effort to limit, reduce, or eliminate any construction effort that would pose a safety risk. It’s more than a list of do’s and don’ts, it’s a culture, it’s part of the DNA of your company about how they perform work and commited to sending their workers home safe.

The legality and science of risk management is quite well known among most contractors and is growing in need to be embraced, understood, and practiced by all specialty contractors. It is wise to take safety seriously, having not only documents that are required but more, have a commitment to see that every worker is educated on, trained on how, and understanding the “why” behind doing things right the first time in the most safe manner possible.

Safety must be everywhere possible in your company. It is in the actions and behavior of our most senior of leaders, including the owner, that sells safety first. A few suggestions on what you can do to demonstrate in action and behavior that safety is first: • Personally invest in safety education.

• Lead safety training workshops personally.

• Make safety related questions part of your daily discussions with field leaders, office workers, field workers, etc.

• Personally investigate when there’s been a safety failure.

• Publicize safety first via signage, posters, proposals, contracts, “grafitti” on company trucks, business cards, and all marketing pieces and internet outlets.

EDUCATE Education most certainly includes actual training workshops and live demonstrations of safe working processes and techniques, but it also affects your company in a few other areas. Consider: • The purchase of hats and shirts that have a clear reference to safety.

• Commit 5-7 minutes of stretching for all workers and leaders…office and field employees.

• Require part of your “pre-con” for the new project to address every safety “risk” potential on the new job.

• Take a brief “safety debrief” after each project from the hourly workers involved with job. If you perform more than one project in a short time span, review multiple projects once a week with your hourly workers.

• Incorporate one positive safety story a week in meetings or share a learning lesson from another company who may have had a safety problem.

RESOURCES Consider all literature, tools, and equipment that should be reviewed, updated, and replaced as needed as it relates to safety.

Commit a budget amount each year for this.

• Inventory your hand tools and consider what needs “sharpening,” fixed, and replaced.

• Are your educational materials clear in

RECOGNIZE & REWARD • Recognize all new milestones of “incident free” goals and the people who are making it happen.

• Engage rewards to include company logo giveaways such as shirts, hats, gloves, etc.

• For exceptional safety performance and results look at some “cash” rewards or tickets, coupons, dinner cards, etc. Be

careful here due to the taxing of such items but provide some form of “hard” proof that safety is saving you money.

• Engage proven workers to conduct the safety training for newly hired employees.

• Consider appointing a “Safety Coordinator” for each work crew and your office. The SC isn’t the safety czar but instead, another outlet for employees to go to with questions, resource needs, etc.

They can also assist foremen on scouting out potentially unsafe work areas, inspect equipment and tools needing repair, and assist in placing orders for new safety equipment.

All the previous suggestions and examples are for naught if we do not practice what we preach and hold people and processes accountable.

• Hold leaders accountable to invoke safety discussions before every project and at the beginning of each new day.

• When leaders do not practice the previous, coach, counsel, and discipline as needed.

• Clearly educate your workers on safe practices and when they do not comply with such practice, coach, counsel, and discipline as needed.

• When “repeat offenders” continue to be non-compliant about following safety rules and practices…counsel, document, and fire!

• Make Safety First mandatory for every employee.

Prevention is the key word here. Prevention in the form of education, reminding, and having needed safety resources and safe working equipment and tools can reduce your risk ten-fold. But we need to clearly communicate safety and be consistent in practicing what we are preaching about safety.
