The new Welcome Center and the seismic retrofit of Heritage Hall mark the first phase in transforming Santa Rosa Junior College’s Roseland Campus, formerly a private K–12 school, into a vibrant college environment. The 5,500-square-foot Welcome Center has wide hallways, tall ceilings, and clerestory windows, creating an open, airy space filled with natural light. ZFA worked closely with the architect to detail exposed trusses and entry canopies that are prominently featured in the building.
Heritage Hall, right next door, required a full seismic and wind retrofit for use as a public school facility, as it was not originally built under the jurisdiction of DSA. ZFA prepared an Evaluation and Design Criteria Report (EDCR), which included a testing program, to establish the approach to design the retrofit. We provided highly detailed analysis of the manufactured trusses, which are not typically found on DSA projects, to justify their use with very minor strengthening required. Our surgical approach to retrofit the building is a testament to our core values: we look for opportunities to justify code conformance of existing construction via creative problem solving and thorough calculations.
