The Moscone Convention Center Project is a campus-wide expansion and new building construction at the Moscone North and South facilities to provide a 600,000 sf contiguous exhibition space, 88 new meeting rooms, a large 20,000 sf kitchen, new main distribution frame/ data distribution and site improvements that includes two new bridges over Howard Street. Moscone Center is the highest LEED rated convention facility in the country. Moscone will be net positive on water, with the largest solar array on a building in San Francisco that generates 19% of its energy needs, and the Center will be carbon emission-free building.

The project included a 110k GAL water treatment plant, new Access Controls/Video Surveillance system, upgraded life safety systems, smoke control, and high-end technology to serve various clients.


As part of the development of the phasing, HCI performed a very intense level of site investigations that included tracing of all structured cabling from the MDF to each IDF, functionality of existing MEP Equipment, i.e. fans, pumps, chillers etc., verification of existing conditions (scanning), and testing of existing BMS and life safety system to validate functionality. As a result of these investigations, HCI’s Kris Kyle, as the lead, was able to develop phasing for the project that included “make ready” phases that moved building systems out of the way of mass demolition. Additionally through the site investigations it was discovered that various building systems were not functional or were not code compliant. It was discovered that the existing Honeywell BMS system was also tied into the fire alarm system which subsequently controlled the building smoke control system. HCI tested the fire alarm and smoke control system according to the existing sequence of operations and found that the system was non-functional and not compliant. After further review the Honeywell controls system was also not functional and did not operate per the sequence of operations. HCI proposed and implemented a solution that severed the life safety component from the building management system and provided code compliant functionality.

In addition, HCI's Brook Mebrahtu held the role of Lead/Senior project manager (previously with SF Public Works) and was in charge of managing the overall $551M public/private development project. He managed the entitlement process, procurement and management of a large A/E team, procurement and management of CM/GC with Core Subs through preconstruction and four-phase of construction that was completed on-time and on-budget.
