Minimizing long-term maintenance was a priority for the owners of this new 25-meter indoor pool with 10 lanes. Our engineers designed the entire structure using concrete, masonry and glass, eliminating metal components that corrode easily. This approach left the structure exposed, requiring close collaboration with the architects on details to meet the project’s aesthetic goals. We also worked with California’s Division of the State Architect (DSA) to gain product approval for the use of sound-absorbing CMU block. Our long-standing relationships within the DSA facilitated a regulatory review process that permitted the material’s first use in a San Francisco Bay Area school.
