Read our feature Building a Better Tomorrow on page 60. Transportation and Construction GIRL’s Career Week for Girls was so popular this year that they had to extend it to three weeks, rather than the usual two. As Colorado Public Works Journal is their Media Partner, I was fortunate to shadow the girls on a couple of the days and once again learnt about the many opportunities in this industry that are open to our graduating high school students. As one girl told me on the very last day “I would accept any one of the jobs from these companies, if it was offered to me”. Industry Events of note that we attended were; The ACEC of Colorado Annual Conference, Women of Asphalt Training Academy Class 2 and T&C GIRL Career Week for Girls. See PS on pages 71-73 for details.

SUMMER 2023┃7 Kleemann | Three solutions for environmentally friendly operation. An overview of concepts and application optionsThree solutions for environmentally friendly operation. An overview of concepts and application options Kleemann uses three different drive concepts that offer the best possible solution depending on the tasks at hand. Although electric drives score very well with regard to the CO2 footprint, in some situations a fuelsaving diesel drive is the better solution. E-DRIVE, D-DRIVE and H-DRIVE represent the variants diesel-electric, diesel-direct and diesel-hydraulic. E-DRIVE – emission-free thanks to electric drive The E-DRIVE concept offers two options: Diesel fuel or all-electric. All-electric operation is environmentally friendly: there are no CO2 emissions on site. A precondition for this is a good power infrastructure, which is often available in quarries or in larger recycling yards. D-DRIVE – the direct and powerful solution The diesel-directdrive D-DRIVE provides power directly from the engine to the crusher. In the last few years, it was possible to reduce consumption, for example, through the load-dependent fan drive of the new EVO2 Generation. With regard to the degree of efficiency, the diesel-directdrive has the edge and fuel consumption is significantly lower. H-DRIVE – for mobile screening plants The screening plants from Kleemann use an effective diesel-hydraulic drive. In this case, hydraulic pumps operate all machine parts such as screen, belts and drive system. The power requirements of the screens are considerably lower than a crusher – fuel consumption during operation is therefoare more favourable. Works News E Q U I P M E N T Road Widener — Road Widener LLC, a leading global manufacturer of road construction equipment, offers the patented FH-R material placement attachment, which provides contractors with 50% reduced labor at 1/5 of the cost of traditional self-propelled equipment. Additionally, the remote-controlled design of the attachment allows the operator of the host machine to control the attachment via remote control — enhancing safety by eliminating the danger of additional workers standing along the jobsite. The FH-R is a versatile solution for material placement, precisely dispensing topsoil, gravel, asphalt, limestone and more — all with an attachment compatible with common machines that contractors already own. “With the current Bipartisan Infrastructure Deal there is a renewed focus on repairing and reconstructing our nation’s roadways,” said Lynn Marsh, Road Widener president. “Now is the time to modernize our infrastructure, making it safer and more resilient. The FH-R allows contractors to get the job done more quickly and efficiently. Our two-step process eliminates the need for grading and sweeping by placing the material right where it needs to go the first time.” The remote-controlled attachment easily connects to most skid steers, compact track loaders, road graders and wheel loaders, operating off the host machine’s engine and hydraulics. It is available in left, right or dual dispensing configurations to take on any roadway around the world. The attachment streamlines a variety of tasks including backfilling, road widening, road shoulder repairs, remediation and aggregate placement. The material is poured into the hopper at the top of the FH-R and then precisely dispensed via remote control in adjustable lay down widths from 1 to 6 feet (.3 to 1.8 meters). The attachment dispenses up to 20 tons of material in under 10 minutes.

SUMMER 2023┃9 Colorado’s Local Technical Assistance Program (LTAP), now in its 38th year, has evolved as much as the industry it serves, but training has always been a mainstay. Charged by the Federal Highway Administration (FHWA) with supporting “local and rural road agencies across the US by providing training…” Colorado LTAP proudly offers an affordable and comprehensive training program focused on developing technical, operational and professional skills. Colorado LTAP’s three tracks offer a robust training experience. It begins with the Roads Scholar I program. Aimed at those newer to the field, this program serves as an introduction or refresher to some of the most important skills and topics. As of Spring 2023, graduates of this program will also be credited with a Road Safety Champion certificate from the National Center for Rural Roadway Safety. Building on the foundation laid out in the Roads Scholar I program by expanding and diving into more detail and complexities of the industry is the Roads Scholar II: Road Master track. Finally, rounding out Colorado LTAP’s offerings is the Supervisory Skills and Development program. This track takes participants through government operations, leadership theory and management skills. These complimentary programs are the perfect solution to agencies looking to define career progression within their organizations. In Works News U P D A T E S COLORADO LTAP Training: A Plug & Play Solution to Career Pathing for Agencies fact, a number of agencies are already utilizing them as their career pathing models with Colorado LTAP tracking all credits and classes. This also serves each individual as the credit is associated with the individual rather than the agency, allowing agencies to better understand a candidate’s training history. It should be noted that the tracks are optional and offerings are open to anyone interested, including those in private industry. Trainings, all taught by industry professionals considered to be subject matter experts, are typically hosted at partner agencies across the state, focusing on providing geographical equity. Additionally, and with a full-time trainer on staff, customized agency trainings are now also available. A recent article by Indeed noted the benefits of career pathing, or the practice of planning an employee’s future career opportunities within an organization, as leading to improved retention rates and employee output, organizational succession planning and overall lower costs, so don’t delay!

SUMMER 2023┃15 CO/WY Chapter - ACPA @COWYACPA for sustainable pavements As global temperatures increase, reducing heat on roadways can help to lower emissions that contribute to climate change. The measurement of surface reflectivity is known as albedo. Lighter colored surfaces reflect more light, and have a higher albedo. Darker surfaces absorb more radiation and have a lower albedo. Surfaces that absorb heat keep temperatures elevated longer, releasing heat that keeps nearby areas hot even long after the sun has set. How is albedo measured? Albedo is a ratio expressed on a scale from 0 to 1. A surface with an albedo of 0 would be impossibly dark, taking in 100 percent of solar energy. A surface with an albedo of 1 would be completely reflective. How can albedo help mitigate climate change? Reflective pavements could lower air temperatures by over 2.5 degrees F and reduce the frequency of heatwaves by 41% across all U.S. urban areas. If all urban and rural roads in the continental U.S. were converted to higher albedo pavements, recent research found the GWP savings would equal 17 million tons of CO2 emissions per year — equivalent to removing roughly 4 million cars from our nation’s roads each year. For more information on albedo and concrete sustainability, refer to ACPA’s column in this issue of CPWJ. Choose concrete pavements to increase pavement albedo and help mitigate climate change! 17

16┃ Colorado Public Works Journal INDUSTRY SPOTLIGHT: IN GROUND SAFETY from utility strikes to confined entry, working below grade is different, difficult, and dangerous By Sean O’Keefe Infrastructure is inherently dangerous, especially for those who build it. In this Industry Spotlight, Colorado Public Works Journal assesses risks and resolutions to in-ground construction challenges of many sorts with a cross-section of safety specialists focused on heavy civil construction and design. Shelby Hone, Trench Safety Specialist United Rentals Founded in 1997, United Rentals, Inc. is the world’s largest equipment rental company with a fleet of approximately 4,700 classes of equipment. Serving construction and industrial sites across the United States and Canada, United Rentals has a vested interest in assuring the safe use and operation of their equipment on countless projects every day. Shelby Hone, Trench Safety Specialist, takes her work to heart, as many industry partners do. “At United Rentals, I know that my work isn’t just selling people things,” says Hone who has been with United Rentals for eight years and was recently promoted to Regional Product Development Manager. “United Rentals works in partnership with clients to help solve problems for companies that build communities. My work focuses on keeping people safe while doing so.” Offering more than 180 rental products related to trench safety and shoring, United Rentals carries everything from trench shielding and hydraulic shoring to bedding containers and a complete lineup of confined space safety equipment. “The OSHA standard requires protective shoring for any trench of five feet deep or greater. There are also many significant safety concerns when people are working in confined spaces,” continues Hone. “That’s where we come in. We assist them with specific products and configurations of equipment to come up with solutions that are not only cost-effective and timely, but failsafe for the people expected to work in that trench. Using the wrong equipment or using the equipment wrong could be worse than no safety at all.” Hone shares that in Colorado, unfortunately, there have been a rash of preventable safety incidents including several deaths in recent years. Broadcasting the importance of trench safety and confined space training is more than a professional obligation, it’s a matter of conscience. Hone and others in the industry reveal that the issue of noncompliance is largely confined to the smaller contractors operating on the single-family residential scale doing sewer line repairs or foundation excavations. Though there are likely a variety of reasons steps are being skipped, the possible consequences are far too great and so far from necessary for the industry’s true professionals to remain silent. “Dirt is unforgiving, and it isn’t worth the risk,” she finishes. “Once you make the decision to enter a trench you are in there and can’t change that. Doing it safely from the beginning and having proper shoring in place is critically important.” Robin Dornfest, President, Lithos Engineering Established in 2015, Lithos Engineering specializes in tunnel and trenchless engineering solutions for underground work and serves a wide range of interests in both the utilities and oil and gas industries. Lithos was formed from the vision of providing clients with recognizable value through thoughtful site evaluations, constructable solutions, and a careful evaluation of risks in geotechnical, tunnel, trenchless, and geological engineering. President, Robin Dornfest, appreciates the complexities of the challenges his team faces every day. “Every project is different,” says Dornfest of a career that spans more than 23 years. “You never know what you’re going to get into down there. Underground construction is very challenging and unforgiving, so you must be prepared for whatever the ground throws at you.” With offices in Denver, Fort Collins, and Salt Lake City, Lithos Engineering’s geographic reach covers some of the most intense geotechnical and geological conditions in the U.S. “Most of our work involves getting down deep enough to tunnel under something, like a highway or a river, for instance. That requires a deep shaft, which always involves a shoring system

18┃ Colorado Public Works Journal to structurally stabilize the initial access point,” continues Dornfest. “A lot of the engineering solutions require shoring and support of excavation, so safety is obviously a huge factor in everything we design.” Though most of the tunnels Lithos designs are less than 10’ in diameter, engineering the initial access can involve any combination of wood and steel falsework to form the roof and walls of the entrance. “The first thing we tell people entering a job site is ‘If you see something, say something’,” shares Dornfest of empowering all to stop work if an unsafe condition is spotted. “Nothing is worse than the loss of life. It only takes one slip, one bad call, and then someone must call a spouse or a loved one.” Dornfest points out that engineering is almost never a one-size-fits-all equation, and safety around excavations is no exception. “It’s important for contractors to understand that the construction means and methods have to be precisely married to the ground conditions in order to develop a solution that protects workers,” he says of the need to think critically about each excavation rather than simply doing something that was successful elsewhere. “With respect to safety, especially with respect to excavations and entering them, safety is everyone’s responsibility.” Kyle Delucero, Regional Customer Safety Trainer, Sunbelt Rentals As a leader in the equipment rental industry, Sunbelt Rentals is consistently advancing the idea of how to best serve customers, communities, and the planet. With a vast network of locations across North America and an expansive portfolio of products and services, Sunbelt Rentals delivers solutions for construction and industrial programs from more than 1,200 locations. Regional Customer Safety Trainer, Kyle Delucero, has been involved in utility and excavation construction for the entirety of his 25+-year career, spending about half of that time in trench safety equipment and OSHA training. “My role is training customers and Sunbelt’s staff on Excavation Competent Person and Confined Space Entry requirements. What I love about my work is helping people solve problems safely and efficiently,” says Delucero. “I predominantly work with contractors who install wet and dry utilities.” Like Hone before him, Delucero points to a spate of fatal incidents involving poor trench safety practices in Colorado and across the country in recent years as a wake-up call to the industry. “I think there could be a lot of reasons these preventable incidents happen – everything from negligence to communication barriers and inexperienced workers,” shares Delucero. “My biggest message to the workforce is no job is important enough to put yourself in danger during excavation work. The tools and methods to prevent accidents are readily available, and they work.” Delucero points out that contractors are responsible for what happens on their job site. When injuries or fatalities occur, the consequences can be more than financial and emotional. They can be criminal. “There have been several cases in Colorado in recent years that have been prosecuted

Of course, on the civil side, settlements and payouts are significant.” Tim Mukoda, Safety Manager, Denver Water Established as a public utility in 1918, Denver Water takes responsibility for the collection, treatment, and distribution of water across the greater metro Denver. Tim Mukoda, Safety Manager, joined Denver Water two and a half years ago on the heels of a 20-year career in the U.S. Air Force. He is double board certified as a safety professional (CSP) and industrial hygienist (CIH) and has made safety in many forms his life’s work. “At Denver Water, the goal is to provide safe, highquality drinking water to about 1.5 million people while keeping our rates low. There is a tremendous amount of infrastructure involved in collecting that water from the mountains, getting it to treatment plants, and then distributing it to people’s homes and businesses,” says Mukoda of a system complexity that few can truly fathom. “A lot of our distribution infrastructure is underground, so the first thing that comes to mind related to safety is Denver Water’s very aggressive line locate program.” Like Denver Water, their counterparts in electric, gas, sanitary sewer, cable, internet, and telecommunications all routinely use the limited ROW running publicly beneath us. Cooperation within this congested arena is a must. “Electricity and gas are the biggest dangers to the people working on our projects and the public,” continues Mukoda. “We make sure the contractors working with us understand that we don’t compromise on safety. We focus on planning the work. So we want utility locates to be thorough and accurate. Not knowing something was there is worse than knowing it was there and hitting it. Accidents happen, other entities hit our lines, and sometimes we hit theirs. Safety is about planning ahead. When we know something is there, we are prepared to deal with it.” Utility strikes and trench safety aren’t the only dangers of underground work. Mukoda shines a light on the hazards of air quality that can exist in confined spaces. “In confined spaces, which include trenches of five feet or more, safety also has to consider air quality. If you are working with chemicals, they will build up inside that trench in ways they wouldn’t in the open air. That condition could become either explosive, flammable, or toxic, so it’s very important to really understand all aspects of safety when working in the ground. If you think about what you are doing, what are the risks, and what good choices can be made, then you are applying the basics of risk management to everything you do.”

SUMMER 2023┃25 Featured Speaker: Karl Mecklenburg Presenting “Teamwork and Leadership in a Changing World” Thursday, 9/28 | 8:30 AM Story-based and full of humor, Karl Mecklenburg’s presentation brings a team together in times of change, and fights complacency in times of success. The lessons life in the NFL taught him about teamwork, courage, dedication, desire, honesty and forgiveness, and goal setting can be applied anywhere. Teams with leaders throughout the organization win. Great teams use the strengths of the individual to help the team win, and the strengths of the team to cover for the weaknesses of the individual. Karl Mecklenburg rose from a college walk-on at the University of Minnesota and 12th round NFL draft pick to a career with the Denver Broncos that included six Pro Bowl and three Super Bowl appearances. Considered the most versatile player in the NFL, Mecklenburg played all seven Defensive front positions—sometimes in the course of a single game. In 1987 he was selected as both the AFC Linebacker of the Year and the AFC Defensive Player of the Year. Since retiring from football, Mecklenburg has been inducted into the Colorado Sports Hall of Fame and the Denver Broncos Ring of Fame. Mecklenburg was a Pro Football Hall of Fame semifinalist for ten consecutive years. Karl has earned Certified Speaking Professional designation from the National Speakers Association. Since retiring from professional football, Karl divides his time between public speaking and his ongoing charity commitments. The Mecklenburgs still live in Littleton, Colorado. Shuttle to the Roadeo Site Wednesday, 9/27 We’ve made it easier than ever to catch all the fun at the National Snow Roadeo with our free shuttle. It runs all day Wednesday from the north (back) side of the Embassy Suites Conference Center, to “The Ranch” – the Roadeo site at the Budweiser Events Center. CONFERENCE HIGHLIGHTS MAJOR SPONSORS
