22 4th Street

This 7 week project at 22 4th Street in San Francisco can be summed up in three words: efficiency, capacity, and maintenance—better efficiency, increased capacity, and decreased maintenance (okay 7 words).  The installation of new base building equipment at 22 4th Steet in San Francisco increased operational efficiency, decreased maintenance requirements, and added diversity and capacity to the existing space. The equipment upgrades project was executed under the constraints of an occupied building and 24/7 call centers; two crane picks were executed in downtown San Francisco with adjacent full time hotels, parking structures, and various other neighbors and tenants.

For this complex facility and confidential client, GCI was tasked with modernizing the existing mechanical, electrical, plumbing, security, life safety, and telecom infrastructures. Working with Syska Hennesey (Engineer of Record), the local utility (PG&E) and Applicant by Design Engineer (Sunshine Engineering), GCI supported a complete electrical and mechanical infrastructure upgrade.  Electrical upgrades consisted of a new 600A 12kV service, three (3) new 4000A single-ended substations and downstream power distribution. Installation of the new service required a complex approach to power cut-overs to support both space allocation for new equipment while maintaining continuity for existing tenants.
