The Saint Vrain office building project, was prepared for the Boulder County Department of Health and Human Services. The project included constructing a new 75,000 square foot, 3-story office building, and the renovation of an existing adjacent 3-story building located in downtown Longmont, Colorado. The project features include an outdoor amenity deck at Level 2, atrium expansion and upper level connecting walkways between the new and existing buildings. The structural design has heavily informed by the sustainability qualities of the project qualifying it for LEED Platinum certification. Structural Consultants, Inc. provided comprehensive structural design services for the project from conception to final completion of the project.
The main structural system for the building is a composite steel frame that utilizes cast-in-place stair and elevator core wall elements for lateral load resistance. The sustainability goals of the owner relating to daylighting, heating and cooling systems, renewable and recycled materials, maintenance programing, and user environment all informed the structural system design for the project. The exterior envelope of the building consists of a combination of store-front glazing, punched opening windows, and cold formed steel studs backing brick veneer, metal panel and stucco finishes. The building is supported on a drilled pier foundation system.
