A cadre of design firms, specialty subcontractors and related project partners paired with McCarthy Building Companies to transform the east end of Washington University in St. Louis’ Danforth Campus with a common vision and purpose of equipping instructors, researchers, staff and students for their next era of academic excellence.
The East End Transformation of the Danforth Campus, also known as Campus Next, has been a two-year, $280 million project that began the day after commencement ceremonies in May 2017 and is reaching substantial completion by mid-May 2019. McCarthy Project Manager Ryan Moss said coordination of complex details and phasing differentiates this project from many others. Campus Next represents the largest capital project ever undertaken on the Danforth Campus.
“This project is segmented into eight subprojects,” said Moss. “The last piece of this entire transformation is McKelvey Hall, which is technically the ninth project…we didn’t break ground on that project until October 2018, so it will be completed in Summer 2020.”
Ann and Andrew Tisch Park, Anabeth and John Weil Hall, Henry A. and Elvira H. Jubell Hall, James M. McKelvey, Sr. Hall, Gary M. Sumers Welcome Center, Mildred Lane Kemper Art Museum expansion, Craig and Nancy Schnuck Pavilion, the underground parking garage and a new, expansive landscape package comprise the components of the East End Transformation. Three brand-new academic buildings and two new multi-use pavilions are included in the project scope.
“The University’s vision was to complete all of these projects as one master project within its 10-year master plan rather taking on each individual building one at a time,” said Ross. “University Architect Jamie Kolker did a phenomenal job orchestrating this vision. McCarthy is honored to partner with him and with the University.”
When the harsh conditions of Winter 2019 hit, McCarthy elected to erect a large outdoor tent – 300 feet long by 80 feet wide – so that work to landscape Tisch Park could continue even though temps dipped below zero. “We kept that tent up for nearly two months and equipped it with light and heaters so we could continue work on this portion of the project,” Moss said.
Except for Jubell Hall, the buildings constructed as part of the East End Transformation all share structural foundations, Moss said, posing the puzzle of which piece needed to be built next to make the conglomeration of connected structural foundations work. “A lot of it was solved through 3D coordination,” he said. “Even five years ago, it wouldn’t have been possible to accomplish this project in this time frame without 3D building technology.”
During Summer 2017, when the project’s mass excavations were occurring in preparation for the series of new builds, McCarthy was directing more than 1,200 dump trucks daily as they carefully accessed the campus. “This equates to one dump truck leaving campus every 60 seconds,” said Moss. “Negotiating that amount of heavy vehicular traffic through an active campus – with students, staff and the public walking in front of those entrances – was a big challenge. Our two flaggers played a critical role in this…we refer to two of these individuals as our rock stars. McCarthy and the University are very proud that we’ve been able to be good neighbors throughout this project.”
Sustainability has been a top priority for the University through all facets of the Transformation. The University is seeking LEED GOLD certification for all the new structures. “Efficiency in building design was paramount, as was using sustainable products and materials whenever possible,” Moss said.
Sumers Welcome Center (25,500 square feet) and the (18,000-square-foot) Schnuck Pavilion look nearly identical on the surface, said Moss, because each has an all-glass façade front from end to end. “The glass on those buildings is 18 feet tall by four feet wide,” he said. “When we first bid out the project, it wasn’t possible to buy glass that large domestically. But by late 2017, we were able to have it fabricated in the U.S. We took some major temporary measures to enclose those buildings before the glass arrived so that construction of the buildings’ interiors could proceed. You’re pushing the ‘envelope’ to evolve to that large of a piece of glass…we needed 350 pieces of glass that size.”
Subsurface exploration for the project was performed by Geotechnology, Inc. Joel Weinhold, regional manager for the firm’s Central Region, said soil borings, lab testing and engineering to assist with foundation design and more was included in Geotechnology’s scope of work. “Excavations on this project reached 40 feet in depth,” said Weinhold. “In comparison, a typical basement excavation may only be 15 feet deep.” He added that the firm worked closely with the structural engineers to provide foundation design for the project. “We performed 51 soil borings to obtain data to assist in the foundation design,” Weinhold said. “The draining system was also a big priority on this project. We analyzed groundwater flow and assisted with overall groundwater and surface water management.” Testing and working with the University’s variety of subsurface limestone and bedrock – each with different capacities and abilities to support structures – was another facet of Geotechnology’s East End Transformation scope of work.
Speaking of subsurface elements, the 790-space subsurface parking garage has been designed by BNIM with features that make it unusually adaptive to future years and needs on the campus, when academic and office spaces may be more in demand than motor vehicle parking spaces. “When visitors enter the parking structure, the first thing they’ll notice is the sheer size of the parking decks,” Moss said. “Typical heights would range from 6 feet 10 inches to 7 feet 2 inches, just tall enough to accommodate a vehicle. This garage’s decks are 18 feet in height.”
BNIM CEO and Principal Steve McDowell said the garage is bathed in natural light, even the two levels below grade. “We’ve been working on the planning and design of this garage for six years,” McDowell said. “The parking structure serves as a gateway to the Brookings Hall arch, which is truly the symbolic front door to the historic hilltop campus. Our design challenges included creating a structure that is very gracious and welcoming, one that enhances first impressions of the campus. Being easy to navigate with flat floors so one has a clear view of all of the garage on each layer when one is inside the structure was essential.” The dramatic slope of the campus is accommodated by the parking structure, whose slope increases by 12 feet as visitors navigate to the west side.
Perhaps the most unusual feature of the structure is its ability to be converted into classroom or office space as needed in future years. “The University is very forward-thinking,” said McDowell. They truly focus on how to maintain the greatest value over the long term and be prepared for future learning environments and demands.”
KPFF is the structural engineering firm of record for eight of the nine East End Transformation projects. KPFF Managing Principal John Miller said specific project challenges included engineering the cantilevered corner on the northwest exterior of Weil Hall. “It’s pretty amazing to see the corner hovering over the welcome court,” said Miller. “At approximately 45 feet by 30 feet, that cantilever is really a spectacular piece of engineering because it has nearly no visible means of support. We have a truss that’s made with very high-strength steel – a tension rod that’s barely visible. It was a creative structural solution,” he added.
Perkins Eastman designed the 86,000-square-foot McKelvey Hall, which will be the new home to the University’s Department of Computer Science and Engineering. Senior Associate Shefali Raichaudhuri said Lead Principals James Butterfield’s and Steven Gifford’s design reflects the masonry Collegiate Gothic exterior of the surrounding buildings, while the courtyard-facing exterior is a multi-story curtain wall providing a dramatic window into the contemporary, state-of-the-art computational research spaces.
Moore Ruble Yudell Design Partner Buzz Yudell said his firm has been working for Washington University in St. Louis for more than a decade on design projects including Hillman Hall, the third facility for the Brown School of Social Work. “While that project was happening, the campus was searching for quite awhile about how to transform and further develop the East End from what had become parking to become a strategically and academically important zone of the campus into a gateway that takes access to the hilltop campus all the way to Skinker Boulevard,” Yudell said. “The goal really started with the academic vision of increasingly supporting more interdisciplinary work. Transitioning from the traditional, Collegiate Gothic look of the campus’ core to a more modern look as you move to the east was a principal challenge,” he added. “Landscape is the piece that unites everything.”
Taking primary and secondary pathways from the historic area of the campus and threading them into the University’s quadrangles – from the engineering district to the north to the arts on the south and unifying it from the big green that connects to Brookings Hall, the campus’ original building built in 1902 – was a major portion of MRY’s scope of work.
MRY’s work included designing Jubell Hall. “Designing a blend of materials such as local stone like that used to build the University’s original buildings with a transitional, more contemporary materials an integrating a broader expanse of natural light in the new structures was a focus of our work in emphasizing collaboration and sense of community across this historic campus,” said Yudell. Even the subgrade level of Jubell Hall, is flooded with natural light, he added. The 80,600-square-foot building features 15,600 square feet of research lab spaces and 3,350 square feet of makers space where future engineers can build prototypes and experiment with robotics.
Mackey Mitchell Architects Senior Associate Daniel Schneider partnered with MRY Architects & Planners on design of Jubell Hall. The late Gene Mackey worked extensively on design aspects of the project before his passing in late 2016. The 80,600-square-foot Jubell Hall houses the School of Engineering & Applied Science’s Department of Mechanical Engineering & Materials Science. Maker spaces, where students build metal engineering parts with their hands, are designed into Jubell Hall. “We designed concrete floors that are 16 inches thick to minimize vibrations,” Schneider said. Themed accent designs are etched into the walls to signify the engineering specialties house therein including a sine wave and fluid mechanics symbols. One notable challenge, said Schneider, was having to shift the design for the garage tunnel connecting Jubell Hall with Uncas A. Whitaker Hall (for Biomedical Engineering) by a foot and a half.
Architecture firm KieranTimberlake’s scope of work on the East End project included designing the all-new, 82,100-square-foot Weil Hall, which houses graduate studios, classrooms and digital fabrication spaces. KT also designed the two small pavilions, Schnuck Pavilion (which offers café dining via an outdoor terrace) and the Sumers Welcome Center, both of which flank Brookings Hall, to appear as contemporary glass jewels, mimicking the more modern look of Weil Hall and the newly expanded Kemper Museum, which KT also designed. KT’s work unites the University’s graduate and undergraduate art, architecture and design spaces into one building.
Michael Vergason Landscape Architects Ltd. led the design of site and landscape for the six-acre Tisch Park to integrate planting and paths to weave the entire project together. MVLA Senior Associate and Project Manager Beata Boodell Corcoran worked in tandem with Vergason. “It’s an important central landscape that emphasizes people, not vehicles,” said Vergason. “Developing a sense of place, building connections between structures on the East End while creating a strong eastward connection to Forest Park was central to our scope of work. Our talented team of multiple design firms integrated a strategy of sustainability that builds on the 1900s plan originally executed by landscape architect Cope & Stewardson. Everything we’ve done builds on the principles of the University’s vision to create a better tie to Forest Park,” he added.
Landscape that allows for an active, strong central green and deciduous trees replete with bicycle and pedestrian paths, Corcoran said, encourages students, faculty and staff to linger. An allee of native trees frames the new greenspace focused on Brookings Hall. A total of some 17 acres of new landscape has been created via this project. “More than 20,000 cubic yards of soil have been designed for this project to ensure the long-term health of the landscape,” said Corcoran.
Specialty subcontractor Winco Windows supplied windows for Jubell Hall and McKelvey Hall as part of the East End Transformation effort. Winco Owner and Architect Gantt Miller said the company’s collaboration with the University has roots dating back decades. Winco’s expertise in developing and providing the window panning system for the University allows for a clean, tight window installation while preserving and enhancing the look of each structure, said Miller.
Golterman & Sabo Architectural Products’ customized acoustical treatment within the new structures on the University’s East End fitted the buildings with sound-absorbing, attractive-looking walls and ceiling panels. Company President and Owner Herb Golterman said the company’s working relationship with the University dates back decades.
