Letter From The Editor
To New Horizons By Luke Carothers
It has been my pride and passion to serve in my role as Editor for Civil+Structural Engineer Magazine . For the last five years, I have been given the unique opportunity and responsibility to peer into every corner of the vast network that is the AEC industry in the service of highlighting the people, projects, and stories that are moving us forward. In this time, I have developed a deep respect for what we have come to know as the AEC industry. One of the things I tell my colleagues, perhaps too frequently, is that, unlike most industries, ours has a direct impact on every living thing within the communities we serve. Good and bad, significant and insignificant, meaningful or banal—almost every single moment of our lives and the lives of those around us takes place within the context of the built environment. As the industry tasked with maintaining and expanding the built environment, we have a unique responsibility to the people and places we serve. This is the foundation from which my view of the AEC industry springs—that we, as the designers of the built environment–have a responsibility to consider and design for this understanding. I believe our industry is one worth celebrating—and celebrating loudly. In many ways, this belief has been a defining feature of Civil+Structural Engineer Magazine from its earliest roots. A little more than a decade ago, the concept of Civil+Structural Engineer Media was born when two separate publications—one focused on civil engineering and the other on structural–were purchased by Zweig Group and merged into one magazine, which over time developed into the digital magazine and media platform we are today. Each of these separate changes were made for the same purpose—to deliver content to our audience more efficiently and more effectively, and to celebrate the best of the best in an increasingly interconnected industry. Now, as 2024 draws to a close and we are all in the process of preparing for what the next year holds, I am excited and proud to announce some big changes happening at Civil+Structural Engineer Media. In 2025, we are moving to a new name and brand— The Zweig List . This move will allow us to continue producing the same insightful and award-winning content you’ve come to expect while also celebrating what we feel are the core components of our industry—people, projects, and practice. Under the Zweig List brand, we will still work to deliver content to you through Civil+Structural Engineer Magazine , but also with new content forms and alternate forms of media. I’m excited to share this news, and I look forward to introducing you to the Zweig List brand in the new year. Stay tuned to our channels in the new year for more updates and opportunities. Humbly & Sincerely, Luke Carothers Editor, Civil+Structural Engineer Media

looking back, moving forward
Stretching almost the entirety of the United States’ West Coast from California to Washington, US Highway 101 (or US 101) traverses many of the most beautiful landscapes the country has to offer. In its southern stretches, this scenic highway clings to the coast along the sunny Pacific ocean before turning inward to traverse hills and mountains forested with ancient towering redwoods. Still further northward, US 101 picks its way from coastal settlement to coastal settlement in places like Oregon where the only practical means of linking these once-isolated towns and cities is to cut a winding path as close to the sea as possible. The plan for US 101 was developed in the early 1920s with plans to link San Diego in the south with Port Angeles on the Olympic Peninsula in Washington. With an increasing reliance on cars for transportation and trucks for the movement of goods, the development of a coastal highway linking major cities along the West Coast became necessary. Around the start of the 20th century several smaller state and inter- state roads had been established up and down the West Coast. One of the primary focuses for a new plan was connecting these disparate highways through a cohesive network. The first stage of this massive inter-state highway project began in January of 1928 when plans were approved for its first section from San Diego to Los Angeles. Plans for the rest of the route were approved shortly after that year, and construction soon began. Perhaps the most notable of the historic roads and trails incorporated into US 101 is El Camino Real (also known as The Royal Road or The King’s Highway). Running a roughly 600-mile route from San Diego to San Francisco, this historic trail dates back to the 17th century when Spanish missionaries used it to travel between missions and pueblos. It was established when the Spanish Portola expedition landed in what is now San Diego in 1769. They were the first Europeans to travel overland through the region, and made their way north to the San Francisco Bay, establishing 21 missions along the way. The route traveled by these Spanish missionaries over three centuries ago still traces the route of US 101 through much of California to this day. A section of El Camino Real became the first paved highway in California as it was incorporated into the Pacific Highway. Two decades later, several sections of the El Camino Real were further incorporated into the expanding stretch of US 101. As the 1920s turned into the 1930s, the completed vision for US 101 was coming to fruition, and in less than a decade from its start the patchwork project of new and existing roads was taking shape.

the course of the next several decades, numerous improvements were made–bypassing sections of dangerous roadway with tunnels, widening sections, straightening curves—and the result was a new era of growth and mobility for a growing population on the West Coast. Coastal and mountain towns up and down the West Coast were connected in a way that allowed for the growth of new industries like tourism, which hit its peak around the middle of the 20th century and waned as new interstates began to bypass the old route taken by the now-old highway. While it's easy to view projects like the US 101 and others as modern feats of engineering, its important to also note the impact that historical trends can have on even the most modern of projects. Within a context of historical trends, networks like coastal highways and the patterns through which they develop can be viewed as an almost natural progression of human movement—giving us an invaluable perspective for past, present, and future.

Setting the Standard for Urban & Green Infrastructure: ISG’s Market District Wins 2024 YEA Summit Award By Luke Carothers
Watson Mountain Middle School, battled for the top spot, intriguing voters with their $111 million project in Loudoun County, Virginia. J2’s submission for the 2024 YEA competition demonstrated a clear impact on the local community, as the project delivered a 211,000-gsf middle school with associated parking, bus loop, and athletic fields. As the second week of voting wore on, however, it soon became clear that one project was beginning to separate from the pack and set itself apart as the top project in the 2024 YEA competition. Another firm making their first appearance in the competition, the results indicate that ISG was able to set itself apart from a group of stellar projects as the 2024 Summit Award winner. ISG’s submission focuses on their Market District project, which aimed to rejuvenate 30-acres of the East Village neighborhood in Des Moines. The project features over 80 bioretention cells, bioswales, and a water quality basin that were designed to treat around 20 million gallons of water per year prior to reaching the Des Moines River. In addition to a focus on the importance of water, the Market District project sets a new standard for urban and green infrastructure by serving as a model for future redevelopment efforts. As you read through this year’s class of the Yearbook of Engineering Achievement and share in this moment of celebration, let these projects also serve as a model for our ambitions in the new year. By daring and executing plans, often lasting a decade or more, the projects that represent the 2024 YEA winning class are a testament to ambition and dedication—laying the foundation for a bright future to come for the AEC industry.
As 2024 draws to a close in its final month , the AEC industry is yet again wrapping up what has become a benchmark year. As a means of commemorating and celebrating such a momentous year, we are proud to announce the 2024 Yearbook of Engineering Achievement, including our 2024 Summit Award winners ISG who took the top spot for their innovative use of urban and green infrastructure in Des Moines. As reflects the achievements of the industry it is meant to celebrate, the 2024 YEA competition soared to new heights this year with ten projects from different states across the country. As the online voting period began, perennial YEA winners Halff entered into an early lead with their submission featuring the RM 620 Railroad Overpass and Roundabout in Round Rock, Texas. Halff, who has been among those honored in the Yearbook of Engineering Achievement in the past, entered the 2024 competition with a project that was years in the making before vastly improving a major east-west arterial roadway through road widening, medians, sidewalks, overpasses, improved at-grade railroad crossings, and much more while ultimately delivering solutions that yielded significant community and environmental impacts. Another project that emerged as an early contender for the top spot was TYLin’s Great Water Alliance Program in Waukesha, Wisconsin. Their first appearance in the Yearbook of Engineering Achievement, TYLin entered the 2024 competition with an incredibly strong project in which they helped a city of 72,000 residents solve a critical water issue while incorporating sustainable practices that protect the environment and sustain the Great Lakes Watershed. Tracing a thread of newcomers to the YEA competition, another firm making their first appearance in the YEA competition in 2024, J2, made a splash in the voting totals through the first week of online voting.

By combining infrastructure with intentional design, the project demonstrates how engineering can enhance urban livability, shifting public perception of its role in community development. The project’s stormwater management system delivers significant social, environmental, and economic benefits. The biocell system, paired with the City’s dual-purpose detention park, mitigates flood risks while creating a public space that promotes outdoor activities and social interaction, fostering a stronger sense of community. Additionally, the project supports environmental remediation efforts at the adjacent Two Rivers Park, contributing to sustainable redevelopment and public health improvements through cleaner water systems and restored natural areas. This project exemplifies how thoughtful engineering can drive urban revitalization and enhance public spaces.
Background The Market District Master Plan aimed to rejuvenate about 30 acres of the East Village of Des Moines by focusing on the importance of water and visualizing it through the use of green infrastructure. ISG has supported and led the plan’s implementation, providing design services at the conceptual, preliminary, final, construction administration, and traffic impact stages. Over 80 bioretention cells, bioswales, and a water quality basin were designed to treat about 20 million gallons of water each year prior to reaching the Des Moines River. The project required coordination amongst a dozen jurisdictional entities and three property owners to meet the expectations and vision of The District Developer, LLC, the City of Des Moines, and MidAmerican Energy. This allowed for an efficient layout of new infrastructure that cohesively connects to the existing systems in place which provided an organized utility design. Impact The Market District sets a new standard for integrating urban and green infrastructure at scale, serving as a model for future redevelopment efforts. ISG’s district-wide approach replaces fragmented, property- specific stormwater solutions with a holistic system that promotes sustainability, long-term efficiency, and urban transformation.

iron and asphalt produced from recycled source materials, the use of American Iron and Steel, stormwater management on the construction site to reduce the impact on surrounding wetlands, and the restoration and expansion of pollinator habitats to offset the effects on local wildlife. One of the Program’s most significant achievements is its ability to maintain a net zero impact on Lake Michigan. Twenty-three miles of force main, known as the “Return Flow Pipeline,” with a pumping facility at Waukesha’s Clean Water Plant, facilitate this process. Using environmentally friendly materials and advanced technologies allowed the team to minimize the environmental footprint while keeping costs down and delivering a project designed to last 100 years. These efforts saved the community an estimated $40 million. The benefits to the public and surrounding Great Lakes area will extend far into the future through the Great Water Alliance Program. Accomplishments & Accreditations • National Recognition Award, American Council of Engineering Companies (ACEC), 2024 • Engineering Excellence Award, ACEC of Wisconsin, 2024 (Best of State) • Project of the Year, Wisconsin Section of the American Water Works Association, 2024.
Background The Waukesha Water Utility (WWU) provides essential water treatment and distribution for a city of 72,000 residents, but they faced a critical issue with a depleting primary water source. The Great Water Alliance Program is a pioneering initiative to solve this critical water issue for the city of Waukesha by diverting water from nearby freshwater giant Lake Michigan. The multi-year, multimillion-dollar Program required adept navigation of complex regulatory landscapes and an exacting approach to balance long-term sustainability and cost-effectiveness for the community’s benefit. Key challenges included transitioning to the new water supply and relocating pumping stations. With 90% of the pipeline located outside its served community, coordination and extensive permitting across seven communities, two counties, and multiple federal agencies was crucial to keeping the project on schedule. The project included 36 miles of pipeline, two pumping stations, two eight-million-gallon ground storage reservoirs, a one-million-gallon water tower, a return flow pumping station, and a new outfall facility. Impact The Program incorporated sustainable practices to protect the environment and sustain the Great Lakes watershed. Key achievements included the use of environmentally friendly materials such as ductile

dimension, pattern, and profile were developed using a combination of regional curve and reference reach data. To provide long-term stability to the urban stream with a developed watershed, boulder j-hook grade control structures and boulder toe bank protection measures were utilized. McAdams worked closely with the landscape architect in developing a robust planting plan of native grasses, shrubs, and trees whose root systems will provide streambank and slope stability and shade to the stream. A substantial pedestrian bridge was an important design element to allow visitors to experience the stream enhancement. In addition to the stream enhancement project, McAdams was tasked with designing and obtaining permits for several other major infrastructure elements that serve Hub RTP and ensure future development within the greater RTP area will have a foundation in place to support ambitious growth plans. Each of these project elements came to fruition as a result of investment of public funding from Durham County.
Background Hub RTP is a 40-acre transformative mixed-use project in Research Triangle Park (RTP). RTP created a new zoning district specifically for this site with the goal of developing retail, hotel and residential uses which had been excluded for the previous 50 years. This project adds amenities that attract visitors not just for work, but for living and playing, allowing RTP to continue competing with alternative research parks worldwide. McAdams developed the initial master plan for Hub RTP and provided surveying, subsurface utility engineering (SUE), stream restoration design, flood modeling, environmental impact permitting and civil design expertise for the infrastructure development. Central to the site lies a tributary to Burdens Creek which had been straightened and banks lined with riprap in the 1960s providing little experiential benefit or ecological function to the site. The opportunity to enhance the stream and establish a centralized, open-space amenity was critical in establishing Hub RTP as a desirable destination. Impact The stream enhancement design modified the existing channel cross- section, incorporated subtle meanders, and adjusted the profile to improve bedform diversity establishing riffle-pool sequences as is typical of North Carolina Piedmont streams.

and CGS. Now that the project has been completed, the students who attend this elementary school and their families can rest assured that this hazard has been properly addressed. The LSRE was constructed as a series of subsurface shear panels oriented perpendicular to the creek adjacent to the school. The shear panels comprise four overlapping columns of DSM. Each DSM column is approximately 6 feet in diameter and ranges from 23 to 32 feet in depth. The columns are spaced approximately 25 feet on-center. In order to meet an extremely tight project timeline, the review process occurred while design calculations and construction documents were performed. Accomplishments & Accreditations • CalGeo Outstanding Project Awards - Medium-Public Category (Honorable Mention)
Background ENGEO performed design services for the design-build construction of a mitigation of liquefaction-induced lateral spreading adjacent to a Bay Area elementary school. Overlapping deep soil mix (DSM) columns were constructed to create shear panels in the ground parallel to the direction of possible soil movement. ENGEO performed analyses to design the DSM panels as well as preparing the construction drawings and specifications in-house. The project schedule allowed for slightly more than five months to perform the design, achieve concurrence by the West Contra Costa Unified School District’s Geotechnical Engineer, and gain approval by the State of California in order to start construction in the School District’s required timeline. During construction, ENGEO performed part-time observations supporting the contractor’s Quality Control team and the Quality Assurance observations and testing by the School District’s team. The project was constructed in the summer of 2021, meeting the project’s tight schedule. Impact The liquefaction and lateral spreading hazard was initially identified several years ago.

691,000 native dune plants of multiple varieties planted. Environmental care was crucial throughout the project especially considering the delicate coastal ecosystem. The creation of habitats and dunes will allow the wildlife in the area to enjoy more of the beach and thrive sustainably for years to come. This project has not only renovated and expanded the beach but it also serves to protect the beach from erosion and damage from the passage of time, weather and hurricanes. The extended shoreline creates an additional layer of protection should extreme weather or other disturbances come to the region. This protects all residents of the town, comma and animals.
Background Dauphin Island is a cherished part of Alabama’s coastline, the 14-mile- long barrier island south of Mobile is home to beautiful beaches and a wide variety of species that inhabit the sky, sea and sand. Erosion, hurricanes, and the passage of time have threatened these critical environments. The current restoration project began with Phase I in 2016, significantly mitigating erosion and habitat damage. Phase II aimed to continue this success, marked as a top priority in the US Army Corp of Engineers’ Final Alabama Barrier Island Restoration Assessment Report. With $22 million in funding from the National Fish and Wildlife Foundation Gulf Environment Benefit Fund and the National Coastal Resilience Fund, this phase replenishes approximately 1.5 miles of shoreline and 88 acres of beach and dune habitats, crucial for seabirds, shorebirds, migratory birds and sea turtles. This unique project ensures Dauphin Island’s East End Beach is a flourishing refuge for wildlife and a peaceful escape for visitors. Impact The project’s impact on Dauphin Island is significant and lasting. The project accomplished the following: 400 feet wider beaches, 1,200,000 cubic yards of sand placement, 60 acres of beach habitat created, 20 acres of dune habitat created, 12,400 linear feet of sand fence and

during project development. The slower roundabout speeds combined with greatly reduced traffic volumes made a roundabout the ideal design for the Chisholm Trail intersection near Round Rock High School. It is now a much safer and less congested intersection for both pedestrian and vehicular traffic. Self-contained treatment units for water quality management were provided for environmental protection of the outfall and the environmentally sensitive Edwards Aquifer and potential habitat of threatened and endangered species. Although roundabouts have recently gained popularity within the region, they were not common during the design phase 10 years ago. Halff produced a computer-generated, first-person drive-through video of the proposed overpass and roundabout, including narration, to educate the public on the project and how to navigate it. Accomplishments & Accreditations • American Public Works Association (Texas Chapter) - Project of the Year, $25 to $75 million Category
Background The RM 620 Railroad Overpass and Roundabout project was years in the making and aimed to improve a major east-west arterial roadway in Round Rock, between Deep Wood Drive and Interstate Highway 35. The project included road widening, medians, sidewalks, overpasses at key intersections, improved at-grade railroad crossings, enhanced storm drainage and water quality improvements. TThe completed roadway includes bridge overpasses at N. Lake Creek Drive and Chisholm Trail Road. The intersection at Chisholm Trail Road was reconfigured from a traffic signal into a roundabout, which is bisected by the at-grade railroad crossing. The bridge overpass extends over the entire roundabout and railroad tracks taking approximately 90% of traffic over the railroad crossing and out of the intersection. The walls and bridges included aesthetic treatments. The aesthetics, safety improvements, and access provided by the roundabout are signature aspects of the project. Impact The project sought solutions that yielded community and environment benefits, while minimizing detrimental impacts.

Background This $111M project delivered a new 211,000 gsf middle school and associated parking, bus loop, and supporting athletic fields on a fast track process. The school, the 100th for the school system, has a capacity for 1,445 students. It is named for the community that it is located in, which was once home to one of the largest populations of free blacks in Loudoun County. This is the first 4-story school for Loudoun County Public Schools. The building was sited on the side of a hill to take advantage of site topography while also adhering to the building height requirements in the agriculture zoning district that it is located in. A master planning process was used to site 3 schools on the property and to study the earthwork necessary to develop and access all 3 schools. Impact The school supports the local community. It's need stems from overcrowding at a nearby school. The school will initially open with 540 sixth graders and it will eventually include grades 6 through 8.

used the dredged material to build up large open water and mudflat areas, re-establish tidal marsh vegetation, increase sedimentation rates, facilitate marsh migration and climate change adaptation and prioritize a matrix approach to habitat restoration that supports critical bird species. The Abbotts Meadow restoration exemplifies how beneficial use of dredged material and fine-grained sediment management techniques can be replicated at other wetland management sites, even on a smaller scale. It also serves as a model for wetland restoration and climate resiliency projects along the coastline. WSP meticulously handled the project’s planning, design, and engineering, and managed the construction of dredging and sediment placement at Abbotts Meadow.

Background The Abbotts Meadow restoration project proved that one project’s trash can be an agency’s treasure. The Abbotts Meadow marsh suffered from years of degradation due to human impact and sea level rise. With every tide, water inundated the 365-acre marsh, was trapped, and could not drain out. The marsh was drowning, and wildlife was suffering. Five miles south, a new port was under construction to serve an emerging offshore wind industry, marshalling New Jersey’s transition to clean energy. The port required access to navigable waterways and creating new channels to connect to deep water in the Delaware Bay. Dredging new channels generated approximately 600,000 cubic yards of clean sediment – the equivalent to approximately 45,000 dump trucks of dirt. As project lead, WSP designed the dredging and restoration projects, from concept through full engineering and permit approvals, to hydraulically pump the sediment to the Abbotts Meadow site. Impact The school supports the local community.

project enhanced safety and reliability for thousands of daily users, ensuring that residents and local businesses continue to enjoy efficient access across the Housatonic River. Environmentally, the use of Ultra High-Performance Concrete (UHPC) was a strategic choice for its durability and extended lifespan—up to 50 years, compared to the typical 20 years for standard concrete. This longevity minimizes the need for future repairs, thereby reducing the consumption of materials and energy required for maintenance. Throughout the project, meticulous planning ensured that construction activities minimally disrupted the local community. Keeping the bridge operational allowed uninterrupted flow of vehicular and marine traffic, supporting the daily routines of residents and preserving access to the Long Island Sound.

Background The Rehabilitation of the historic Devon Bridge stands as a testament to M&J Engineering’s commitment to preserving vital infrastructure with innovative solutions. This bascule draw bridge, stretching 859 feet across the Housatonic River and linking Stratford and Milford, is the longest drawbridge on the Boston Post Road and has been listed on the National Register of Historic Places since 2004. To restore this vital structure to a “State of Good Repair,” M&J, working with Mohawk Northeast, Inc., Close, Jensen & Miller, P.C., and the Connecticut Department of Transportation (CTDOT), undertook extensive efforts to address the structural deterioration and wear affecting its steel and concrete elements. As part of the scope of work, the rehabilitation addressed balance issues related to the bridge’s movable span. In preserving this historic drawbridge, M&J Engineering’s team honored its storied past while preparing it for continued service, showcasing a blend of technical expertise and respect for Connecticut’s engineering heritage. Impact As a historic structure and vital connector between Stratford and Milford, the bridge supports a substantial flow of both commercial and residential traffic, easing pressure on nearby routes such as I-95.

Clemson University’s world-class Women’s Sports Complex demonstrates its unwavering commitment to equity in sports
A New Standard in Collegiate Women’s Sports
a rowing center renovation and a new 10,000-square-foot elite athlete training and recovery center. Clemson held a groundbreaking ceremony in December 2022. By January 2024, the women’s lacrosse, gymnastics and rowing programs cut the ribbons on their new and updated, state-of-the-art facilities, setting a new US standard for women’s sports and an industry precedent for how fast visionary architecture can be designed and delivered. Fast-track design and construction HNTB and South Carolina-based architectural firm Garvin Design Group were tapped to design and build the new spaces on a fast-track timeline. The HNTB-Garvin project partnership allowed the two firms to complete plans for three new buildings, the rowing center renovation, and the lacrosse stadium in just nine months. To accelerate construction, the design team leveraged the speed and efficiency of pre-engineered metal buildings. The prefabrication

Within 18 months of introducing two new women’s sports programs— lacrosse and gymnastics—Clemson University had planned, designed, and broken ground on a world-class Women’s Sports Complex. “When Clemson Athletics commits to facilities, best is the standard,” said Clemson Executive Senior Associate Athletic Director Eric Sabin. “The new Women’s Sports Complex reflects our dedication to lacrosse and gymnastics and to women’s sports overall. Our strategy was to design the best in the country for those student athletes.” To ensure that the complex would fit within the athletic district, an area on the west side of campus that is home to all Tiger athletic facilities, the Athletic Department chose a site overlooking Lake Hartwell, adjacent to the women’s rowing building. Project leaders established a scope that included not only lacrosse and gymnastics facilities, but also

engineer shared standard baseline details, and the team tailored those details to align with design goals. The structures were highly customized with high-end exterior and interior finishes, light wood tones, added windows and energy-efficient systems, resulting in a first-class, aesthetically pleasing complex. Each building has its own distinct space, personality, scale and interior detailing, giving athletes in each sport an individual sense of identity while maintaining commonalities with other Clemson buildings to unify the new sports complex with the rest of the campus. Empowering athletes through design “In every endeavor, Clemson holds itself to a standard of excellence,” said HNTB Design Principal Eric Maxwell. “When they start a team, their posture is to invest and position the athletes to immediately be competitive and win.” The 21,000-square-foot gymnastics operations and training facility boasts a lobby, practice gym, offices, locker room, lounge and training room. A large expanse of polycarbonate panels on the south and southwest sides allows sunlight to filter through a line of trees outside, bathing the interior in an ultrasoft light that helps enhance performance. The gymnastics coaches wanted the exercise floor to be the centerpiece of the training space. Designers brought that vision to life by creating a light-filled lobby that provides spectators and visiting summer camp families with unobstructed views of the exercise floor.
To accommodate practices, when gymnasts require a mirrored wall, the design team created a sliding partition of mirrored panels that expands for practices and contracts for compact storage. The training space also features hydraulic lifts that allow for effortless adjustment to the landing pad height, enhancing the flexibility of practice techniques for the gymnasts. “The gymnastics facility is a great example of the HNTB/Garvin display of teamwork and commitment to the project,” Sabin said. “Garvin echoed the Athletic Department’s desire for a lot of natural light, and HNTB’s experience using polycarbonate panels and other substrates allowed that light to be diffused so it did not interrupt training in the facility. “Together, they created the most beautiful aspect of the Women’s Sports Complex. Driving up the hill toward the complex, people see the wall face of polycarbonate panels with the largest Clemson paw graphic we’ve ever placed on a facility. Inside is the perfect shadowed outline of that paw through the polycarbonate, with all this natural light coming in. It’s very well designed.” The 9,000-square-foot lacrosse operations building encompasses coaches’ offices, locker rooms, a player lounge, nutrition center, team meeting room, and athletic training room. Across the parking lot at the lacrosse building, the lobby serves as a jewel box display case for Clemson’s paw print brand mark and lacrosse team equipment displayed on interior walls. Interior spaces emphasize the building’s connection to the adjacent field: the head coach’s office and the team

lounge feature full-height glass walls that open directly onto the field. A bold orange portal marks the entry to the “hype tunnel” between the field and the locker room. Custom lockers, showcasing player jerseys and a tiger stripe motif in Clemson purple, are illuminated by panels that divide niches for hanging lacrosse sticks. Tunable track lights run along the underside of an uplit pan ceiling, while warm wood softens the textured white tile and frames a wide clerestory window above the vanity in the bathroom. The stands and press box at the lacrosse stadium mimic the form of the adjacent buildings, but aligned with its function, the massing promotes views to the artificial turf competition field and lake views beyond. The stadium includes 1,000 spectator seats, spaces for concessions, restrooms and locker rooms for visiting teams and officials. The woods beyond slope down to Lake Hartwell and offer a unique backdrop to the athletic field. “Our facility is more than we could have ever dreamed of,” said Allison Kwolek, Clemson Lacrosse Head Coach. “Everything about it has been better than expected. For a young program to have a world-class facility like this is a game changer for recruiting top student athletes. The design team was genuine in wanting to know our thoughts and put an incredible effort into transforming our ideas into a meaningful and beautiful design.” In February 2024, just one month after the ribbon cutting, the stadium hosted the team’s season opener, which the Tigers won decisively.
Clemson is the only school in the country with a performance and stadium facility solely dedicated to women’s lacrosse. The rowing facility was upgraded with a new sports medicine area that features taping tables, hydrotherapy, and administration offices. The most innovative aspect of the project is the first-of-its-kind, 10,000-square-foot Athlete Recovery Center, a retreat for all Clemson student-athletes to engage in mental and physical wellness practices in an environment that emphasizes recovery and community. “Athlete performance centers usually have the lion’s share of square footage dedicated to cardio and strength training, with recovery off to the side,” Maxwell explained. “The idea behind Clemson’s Athlete Recovery Center is that it’s a place to come take a breath, to retreat from the mental and physical rigors of their day-to-day lives, where they are always trying to get faster, stronger, and smarter, and take time to relax and truly recover.” Acknowledging the need to serve the whole individual, the project team incorporated a large yoga space and the latest recovery equipment, including dry and wet float tanks, TheraLight beds, sleep pods, massage chairs, and cryogenic chambers. Coaches, doctors, and sports psychologists have offices on-site, and the building is positioned to take advantage of the view to Lake Hartwell. The recovery center also plays host to programs that focus on furthering Clemson student- athletes’ holistic development.
