Abstract
The objective of this review is to analyze and evaluate the fire safety of a 5-story office building located in the Moffett Park District in Sunnyvale, California. The building is constructed largely of mass timber and classified as a Type IIIA building used primarily as office space. The first section of the report focuses on the building’s defining characteristics and use cases. The second portion of the report presents a comprehensive review of egress design, fire alarm systems, fire suppression systems, structural design, implementation of mass timber elements, and flammability requirements. The results of the analysis show that the building complies with current prescriptive requirements.
The ensuing section of the report provides a performance-based analysis that reviews two design fire scenarios. The first design fire scenario involves a fire lobby, which is an intervening space along a primary egress path in the building. The analysis showed that the space reaches untenable conditions within 40 seconds. The RSET for the building is 26 minutes. Since this fire opens occupants to significant hazards, it is recommended that the fuel loading in the space is reduced. The second design fire scenario explored sprinkler activation within a team work-pod on the second floor. This space restricted the size of a fire within an otherwise open environment with high ceilings. Sprinkler activation in this area occurred at 351 seconds and provides coverage within the space.
