The 1200 Intrepid project is a USGBC LEED Gold certified four-story mid-rise building boasting 94,000 ft2 (8700 m2) of high-end office space. The predominant feature of the design is the building’s eastern elevation, which makes use of compound double-curved, load-bearing precast concrete façade panels fashioned to echo the circular geometry of an adjacent park. The curvilinear wall was designed with an impressive 22-degree tilt out over the adjoining pedestrian walkway to create an exterior suggestive of a ship’s bow and pay homage to the site’s maritime history. Building information modeling (BIM) software was used to ensure proper alignment in each of the 421 architectural concrete panels. The precast exterior employs interlocking embeds within the concrete, eliminating the need for traditional precast spandrel panels. Each precast panel on the inclined façade has a unique slope and different angle of rotation. Computer-generated cut sheets delineated embed layout and formwork construction. Architectural self-consolidating concrete mixtures were used to produce panels with exceptionally tight tolerances and ensure uniform window frame alignment.
