SPRING 2023┃5 CO/WY Chapter - ACPA @COWYACPA Concrete Pavement MAKING THE GRADE ON INFRASTRUCTURE SUSTAINABILITY Optimizing pavement with expected use and performance conditions in mind can improve costs and reduce lifetime CO2 emissions. Two-thirds of a pavement’s total environmental impact over its lifetime often occurs during the phase in which the pavement is in use – well after material and design selections are made. Concrete is an economical, costeffective pavement solution that consumes minimal materials, energy, and other resources for construction, maintenance, and rehabilitation activities over its lifetime. Because of its rigidity, concrete pavement deflects less under vehicle loading, which results in reduced vehicle fuel consumption. Here’s Why Concrete pavement’s lighter color helps mitigate urban heat island effects and can help offset global warming. Concrete pavement is 100% recyclable, suitable for use in new concrete pavement, base materials, or controlled fill. Concrete pavement can periodically be renewed through diamond grinding, prolonging its lifespan, enhancing its smoothness, and improving its skid resistance. LONGEVITY INCREASED REFLECTIVITY RIGIDITY RENEWABLE RECYCLABLE ENVIRONMENTAL IMPACT

6┃ Colorado Public Works Journal Works News E q u i p m e n t Samoter/Asphaltica 2023: Sustainable Wirtgen Group Technologies for the Road Construction Industry From May 2023, the Wirtgen Group will be presenting a cross-section of its extensive product portfolio with 11 exhibits from Wirtgen, Vögele, Hamm, and Kleemann in Verona. The solutions at the show ranged from cold milling and cold recycling to asphalt paving and compaction, and the processing of natural stone and recycling materials. The focus was on the machines and, above all, on their digital assistance and documentation systems. How Production Systems Are Changing the Face of Road Construction. In the future, modern road construction will be possible only with sustainable and efficient solutions that fulfill the growing demand for protection of the environment and the safety of humanity and nature. In view of this, the Wirtgen Group supports its customers not only with innovative solutions for individual machines, but also with the development and realization of “green” drive system technologies. Much more than this, with its production systems, the group provides the end-to-end solutions that customers need to be able to cost-efficiently and sustainably realize their (road) construction projects. Apart from correctly-dimensioned machines or machine combinations, this includes ideally optimized applications and methods. It also includes appropriate (digital) assistance or telematics and automation systems, documentation systems, and application-specific equipment options that support the processes involved. Highlights of the Wirtgen Group booth at Samoter/Asphaltica 2023 was the Digital Assistance and Documentation Systems exhibit of the Wirtgen Performance Tracker (WPT), which can be seen in the Wirtgen W 100 Fi compact milling machine and the W 200 Fi large milling machine. The system enables the precise documentation of milling performance and automatically generates a report that can be sent by e-mail to the machine Komatsu Showcase At CONEXPO-CON/AGG 2023 owner. This reduces the time, effort, and costs required for the completion of projects. In addition to a range of high-performance road pavers from the Mini to Universal classes, Vögele will also be presenting its digital solution for construction site documentation. As an example of this, the SUPER 1803-3i wheeled paver is equipped with WITOS Paving Docu and RoadScan, the contactless temperature measuring system for temperature monitoring of the entire paved surface. The combination of these two systems also enables quick and easy February 9, 2023 — To help meet worker shortages and increase jobsite productivity, Komatsu is committed to offering tools that help customers best deploy their workforce and optimize operations.

SPRING 2023┃7 Works News E q u i p m e n t John Deere to Roll Out Latest Construction Technologies, Including Industry-Firsts, at CONEXPO-CON/AGG 2023 At this year’s CONEXPO-CON/AGG show, John Deere showcased its latest technology offerings including advanced vision and object detection solutions, SmartWeighTM, standard EZ Grade on P-Tier small dozers and a variety of other grade management and automation solutions available to customers. IMPROVE JOBSITE SAFETY The next generation of John Deere production-class and utility-class loaders are specifically designed to improve operator visibility and awareness. As a direct response to demand from operators, select models can be equipped with new vision and object detection technology. This technology can enhance visibility and help detect obstacles that present jobsite risks. Object Detection technology, paired with a high-resolution camera and a dedicated display, helps enhance the operator experience and increase situational awareness. In addition, the industry-first vehicle trajectory logic technology overlays the projected vehicle reverse path to illustrate where the vehicle will move next. Building upon the object detection enhancements, the industryfirst Advanced Vision System integrates two digital cameras on the sideview mirror frames, helping to provide increased visibility to the sides of the machine. Within the cab display, operators benefit from an integrated view of all cameras, helping to increase spatial awareness with wider views and enhanced clarity. The next phase of Deere’s technology journey can be found with SmartDetect and SmartDetect with Assist. SmartDetect combines cameras and machine learning to help give operators a better view of their surrounds. The system alerts operators when an object enters the machine’s projected travel path and provides unique detection alerts for people in the camera’s entire field of view. With SmartDetect Assist, the machine will automatically stop before coming in contact with a person. INCREASE EFFICIENCY One of the more advanced technology solutions that was on display at the show was SmartWeigh, which is now available on the full lineup of P and X-Tier utility wheel loaders and will soon be available on the production-size P-Tier models as well. Aimed to improve cycle times when loading trucks or processing plants, this payload weighing system delivers increased accuracy, dynamic weighing capabilities, and ease of calibration. This John Deere designed-andsupported solution helps operators confidently hit loading targets and minimize material loss. Available fully equipped on loaders from the factory or as a 250-hour trial period, customers that do not typically utilize payload weighing systems can experience the benefits first-hand, helping to prove value and give them the highest levels of productivity on their jobs. As part of the SmartWeigh system, the dynamic bucket weighing technology eliminates frequent raising and lowering of the boom. The bucket capture height can be set anywhere between 15-90% of boom height and can be captured at any boom speed. Another key feature is that unlike other payload weighing systems, SmartWeigh does not require calibration with a known weight. This enables customers to easily calibrate the system themselves without the need for outside assistance. On top of this, payload weighing data is integrated into JDLink™, meaning it can be accessed nearly anywhere and not just within the cab of the machine. Also new to the P-Tier and X-Tier wheel loaders, Auto Level technology is designed to eliminate frequent bucket and fork adjustments. Operators moving or handling material do not have to worry about the load tipping too far backwards or forwards as the boom is raised up and down. This feature offers near perfect parallelism throughout the entire raise and lower cycle + or - 2 degrees.

SPRING 2023┃13 Practical Pointers on Worker Well-being How can employers help their workforce? • Adopt a culture of wellbeing to combine physical health and emotional health • Communicate to all employees that “it is ok to not be ok.” • Acknowledge that these are trying times and that the company cares about them and their families • Share information about mental health support services for employees to share with their loved ones • Encourage leaders to be intentional in demonstrating care for workers by being visible and vocal about mental health and to be vulnerable about seeking help themselves or for family members What can be done to encourage construction workers to consider their mental health and wellness and seek help? • Double-down on physical health to promote wellbeing, including warmup exercise programs, nutrition, hydration, and stress management skills, like deep breathing • Reduce barriers to care seeking by promoting onsite wellness and health services • Actively communicating about the importance of mental health reinforces that seeking help is a sign of strength and not a sign of weakness • Provide training to teach peer leaders to be mental health and wellbeing champions and peer coaches • Educate workers on their employee health and welfare benefits What can companies do to reduce the elevated risk of suicide among construction workers? • Incorporate mental health and wellbeing into apprenticeship programs • Focus on reducing the frequency and severity of musculoskeletal injuries which creates chronic pain, disrupts sleep, contributes to fatigue, and leads to unnecessary opioid pain management prescriptions • Aggressively promote the Employee Assistance Programs, as well as 988 (3-digit Suicide and Crisis Lifeline) and Crisis Text Line • Conduct Toolbox Talks on various topics relating to physical health and mental wellbeing topics • Create a custom hardhat sticker to show support for mental health How can workers help colleagues? • Make a personal commitment to be a quality teammate • Be observant and go to a crewmate to ask if they are ok when you see changes in their behavior • If the crewmate says they are fine, it is ok to say “you do not seem fine. I care about you. I have rough times too, let me know if I can help. I am here for you if you want to talk or need support.” • Commit to being your brother’s and sister’s crew and adopt a mindset of no person left behind and being there for every crew mate Excerpts of an article by Cal Beyer, Vice President, Workforce Risk and Worker Wellbeing of Holmes Murphy.

14┃ Colorado Public Works Journal Upward Mobility, Westminster engages Envision to rethink wastewater By Sean O’Keefe The fundamental thread connecting people and the places we build; infrastructure can be defined as any public works system that organizes human behavior. Highways, airports, and railways may come to mind, but infrastructure also encompasses all the utilities required to wash, flush, power, and broadcast our lives with the push-button ease we have come to expect. In that cooperation among many is essential to collective human betterment, the need for an organizational framework for society stretches back to the earliest days of human existence. And wherever there is infrastructure, be sure there is a need for infrastructure management. That’s where a special breed of built-environment professionals resides. Tanner Kraft is one of them. “I am the Plant Superintendent at the City of Westminster’s Big Dry Creek Wastewater Treatment Plant. I started as an intern and worked my way up. Wastewater management offers a lot of upward mobility, so it has been a great career path,” says Kraft who has been at the switch in Westminster for three years as the Plant Superintendent, a position he earned through conscientious devotion to his craft, same as any other expert in their field. “My job requires an integrated understanding of all of the parts and pieces of Wastewater from process control within the plant, capital improvements, staffing, and regulatory compliance; to coordination with stakeholders, state government, and the public. People may be surprised to know that there is never a dull day in wastewater.” With a population of approximately 116,000 residents living in both Adams and Jefferson counties, the City of Westminster is the eighth most populous city in Colorado and one of the key suburban centers in the metro-Denver ring. Westminster’s mission is to provide core services and foster economic resilience to give their community the opportunity to thrive. Wastewater management is certainly an essential service, and as such the lineage of the Big Dry Creek Wastewater Treatment Plant very much mirrors the history of Westminster. “This plant first opened as a 1.0 Million Gallon per Day (MGD) facility in 1972, when the city’s population was around 19,500 people,” shares Kraft. As the story of the plant reveals, the evolution of infrastructure often parallels the trajectory of the society it serves. As people and places change, so do their needs, putting pressure on infrastructure to keep pace with progress. “The first iteration of this plant used stabilized lagoons. In 1979 the plant was expanded to 2.0 MGD and introduced a biosolids thickening facility. This allowed the biosolids output to be land applied as organic nutrients.” In 1982 the plant was expanded again to achieve an output of 5.5 MGD and incorporate aerobic digesters, which involve the bacterial conversion of organic matter into carbon dioxide. By 1995 when the city’s population reached 70,000, the plant was expanded to 7.5 MGD and the city-owned farm where the biosolids were being land applied relocated from within Westminster to a site east of the newly built Denver International Airport. In anticipation of more stringent regulations, in 2009 the city completed a fourth expansion and

SPRING 2023┃15 changed the main treatment process to a Biological Nutrient removal process, by which ammoniacal nitrogen is converted to nitrogen gas and phosphorous is removed. “It’s probably fair to say most wastewater treatment plants have gone through a similar evolution,” says Matt Gough, a Vice President at HDR, the firm hired to design the Big Dry Creek Plant’s latest iteration of now. Like Kraft, Gough has made a career in wastewater and agrees, it’s never boring. He has been working with the City of Westminster for more than 16 years and takes a lot of pride in solving problems with clients, stakeholders, and the public within these complex, vital facilities. “In 2018, Westminster started looking at their land-applied biosolids processes for efficiencies. Biosolids are about 98 percent water. The round trip from the plant to the farm is a 100-miles. They were hauling 28 loads a week, which is expensive in fuel, carbon emissions, and manhours.” The solution - a biosolid dewatering facility. In this case, a high-speed rotational centrifuge densifies biosolids from 98 percent water to 80 percent water. Though the change seems small, it decreased the number of roundtrips from 28 trucks a week to just 8 or 9. In doing so, the City of Westminster achieved the prized triple net bottom line. From the reduced fuel costs and environmental impact to decreased truck traffic locally and the outward spread of those benefits, the new dewatering facility is economically, environmentally, and socially beneficial all at once. “One of the early decisions was the desire to pursue an Envision Certification, which is a sustainability and resiliency framework for infrastructure,” continues Gough, who as the Project Manager, played a key role in implementing the process. Developed by the Institute for Sustainable Infrastructure, (ISI) Envision spawned from a collaboration between ISI and Harvard University’s Zofnass Program for Sustainable Infrastructure. Envision uses 64 different sustainability and resilience indicators as credits for measuring a project’s performance around five categories – Quality of Life, Leadership, Resource Allocation, Natural World, and Climate and Resilience. Envision Categories of Considerations • Quality of Life – Addresses a project’s impact on host and affected communities, from the health and well-being of individuals to the well-being of society as a whole. • Leadership – Project teams are most successful if they communicate and collaborate early, involve a wide variety of participants, and take a long-term, holistic view of the project. • Resource Allocation – Resources are assets that are needed to build infrastructure and keep it operational. Concerns include the quality, source, and characteristics of these resources related to sustainability. • Natural World – Infrastructure impacts habitats, species, and nonliving natural systems that perform critical ecosystem services that clean air and water, produce healthy food, and mitigate hazards to our health. • Climate and Resilience – Minimizing emissions that contribute to climate change and ensuring infrastructure resilience through projects that are informed, resourceful, robust, redundant, flexible, integrated, and inclusive.

16┃ Colorado Public Works Journal Those who apply it typically find that Envision organizes owners, designers, and builders in finding ways within the project to cost-effectively reduce resources. In addition to the credit-based project evaluation system, the framework also offers individual credentialing for Envision Sustainability Professionals (ENV SP), who are considered subject matter experts in sustainable and resilient civil infrastructure. Though HDR was one of the framework’s founding partners, applying Envision to the plant was a first for Gough and the team at the City of Westminster. Gough feels fortunate to have had so much in-house knowledge of the process at his disposal. “HDR has some very knowledgeable people on Envision that showed us how to improve our scoring without making needless investments,” he shares. Whether you have an expert on-hand or not, Gough recommends that anyone applying the Envision process for the first time should seek counsel from people who have been through the process. “The City of Westminster has some ENV SPs on staff, so they were very knowledgeable, as well. There wasn’t a predetermined score we were trying to achieve. Rather than chasing points, we looked at everything and tried to find solutions that improve operations by creating efficiencies.” One of the most unique features of the new dewatering facility is how the biosolids are dewatered and distributed to the haul trucks waiting to take it to the farm. HDR and the City spent nearly two years planning and designing the facility by considering ways to make improvements to what had been done elsewhere. “Most dewatering systems densify the material on one level and then use conveyors to move it upward to the haul trucks outside,” says Gough of what the team identified as a common single point of failure in dewatering plants. “We made the facility taller and elevated the centrifuge above the trucks, which allows gravity to fill them. So, we deleted that point of failure and conveyors are no longer an issue for maintenance, operations, safety, or anything.” For those who have never worked on an Envision project, Gough points out that one of the biggest differences from other certifications is that scoring includes credit for community engagement as part of the process. “There is a new development going in just south of the plant, so we used it as an opportunity to conduct some public information programs aimed at educating people about what wastewater is, what we do, and where it goes,” he notes of a point within the program. “Envision also pushed us hard to consider locally sourced materials, recycled building materials, and waste reduction strategies. The scoring is holistic.” In the final count, on paper, the Big Dry Creek Wastewater Treatment Facility earned a Bronze-level certification with Envision and also scooped up an Honor award from ACEC Colorado in 2022. In terms of wins for the citizens of Westminster, there are many. For starters, the plant is now rated at 11.9 MGD, which is expected to serve the City’s needs without further expansion for many years to come. The decrease in hauling operations was so significant that the City had to rethink its drivers’ jobs. “We went from 28 to 8 trips most weeks, so we had three drivers that suddenly needed a lot more work,” shares Kraft of a benefit so deeply embedded in the outcome that it didn’t make it into the Envision scorecard. “So those guys are now in the process of getting their wastewater operator’s licenses and being trained on running the dewatering plant. Soon they will be both drivers and certified water professionals. As I said, there is a lot of upward mobility in wastewater.”

2┃ The Road Ahead INTRODUCTION Welcome to THE Road Ahead - Tom Peterson 2023 is a celebration year for CAPA as it marks the 40th Anniversary of the association. Incorporated in 1983, the association has grown to over 260 member organizations and is the largest state asphalt pavement association in the United States. We thank our forefathers for the heavy lifting and establishing a rock-solid mission of “advancing the use and quality of asphalt pavements in Colorado.” Here are a few CAPA Fun Facts: • A few of the early CAPA pioneers were Skip Bettis of Siegrist Co., Bill Pakovich of Brannan Sand & Gravel, Bob Bisgard of halt Paving Co., Bob Wolfe of Western Paving, Herman Altergott of Best Way Paving, and Bill Lauer of Sterling Paving. • The original name was the Colorado Asphalt Producers Association. It was changed to Colorado Asphalt Pavement Association in 1994 to reflect the new user-producer organization and having affiliate agency member organizations. CAPA is one of only three state asphalt pavement associations in the country that have affiliate agency members and today, there are nearly 80 city, county, and towns that have chosen to be member organizations of CAPA. • John Boring was the first Managing Director and the late Rick DeLacastro followed and served from 1985 to 1992. It was under the leadership of Scott Shuler (Director from 1992 to 1997) that the Laboratory for Certification of Asphalt Technicians (LabCAT) was started. We will be celebrating our rich history throughout the year and have plans for a mid-summer steak fry to showcase our achievements and recognize those that were instrumental in our accomplishments. Enjoy this issue of THE Road Ahead and congratulations to all of the recipients of the 29th Annual “Best in Colorado” Asphalt Awards. Truly the best of the best. Thomas Peterson, P.E. Executive Director Colorado Asphalt Pavement Association
