Edward A. Doisy Research Center & Cloister Walk at Saint Louis University
The walk was originally designed as cast-in-place, but the Concrete Strategies team recommended a switch to tilt-up for a more cost-effective, safer, and better quality product that also cut the original schedule in half.
Concrete Strategies performed the tilt-up concrete for the Cloister Walk and the structural concrete for the 10-story research center on the Saint Louis University medical campus. The Cloister Walk features more than 300-feet of brick and tilt-up concrete structure and is the longest covered walkway on campus. The walk was originally designed as cast-in-place, but the Concrete Strategies team recommended a switch to tilt-up for a more cost-effective, safer, and better quality product that also cut the original schedule in half. Unique in its construction, the structure required panels to be poured in an arch form, featuring a base at one end with the opposite end bolted into the side of the next panel. Nothing like this had ever been done before with tilt-up. The Cloister Walk project involved 8,763-square-feet of tilt-up panels.
The research center is situated on a 9-acre site with elaborate landscaping featuring a stream, Zen garden and fountain. The project’s contemporary design includes exterior steel, brick and 48,000-square-feet of glass that allows natural light to flood the interior. Among the building’s numerous sustainable elements are a green roof, energy-efficient heating and cooling systems, recycled steel, concrete and floor finishes, materials from rapidly renewable sources such as bamboo and cork, as well as recycling 79 percent of all construction waste. The design-build project was completed in just 522 working days.
The research center includes 80 labs spanning eight floors, which have a flexible, open design so researchers from complementary fields can share knowledge as they conduct experiments. The building also includes a 10-story tower with its first two floors extending south, connecting via a covered walkway to the Saint Louis University School of Medicine.
