Seattle Art Museum Expansion and Renovation, Seattle: High-rise 300,000 SF expansion and 100,000 SF renovation of existing SAM Robert Venturi designed building. The expansion of SAM includes 12 stories of Gallery space, a new 10,000 SF Restaurant, a new Museum store, and a Forum. The Museum HVAC system is floor by floor chilled water AHUs with hot water heating, humidification, 30/85% filtration, carbon filtration, sound attenuation, VFDs, and redundant fans. Central centrifugal chillers located in the base of the building make chilled water to serve the building AHUs.  AHUs serve cooling only VAV boxes with hot water heat and zone humidification throughout the Seattle Art Museum Facility. The facility operates 24x7 and requires N+1 redundancy in the central plant. The first 12 stories of the Bank are adjacent to the Seattle Art Museum and break-out glass does not exist for the Bank or Museum on this adjacency. This creates the necessity to have the Buildings mechanically smoke controlled. To reduce risk of a potential software problem, the Museum’s DDC system is NOT integrated with the smoke control and fire alarm systems. Smoke control and Fire Alarm systems are all completely hard wired and do not rely on software to manage emergency operations.

Venturi Building renovations included a new lobby configuration, special exhibition space, gallery renovations, office remodel, improvements and expansion to the existing chilled water system, and complete DDC controls and fire life safety system upgrades. A phased temporary ventilation plan was created to allow continuous 24x7 operation of the building environment for art storage and occupied administrative areas during construction. Services included HVAC and plumbing design, cost estimating, construction administration, and project management.
