This is a General Contractor/Construction Manager (GC/CM) contract document for the Seattle-Tacoma International Airport (SEA) located in Washington State, with Mortenson Construction designated as the GC/CM. The Concourse HVAC Infrastructure Renewal/Replacement Program (CHIRRP) encompasses the phased renewal and replacement of aging HVAC infrastructure serving Concourses B, C, and D at SEA. The project addresses critical system deficiencies including insufficient air supply capacity, equipment at or beyond service life, absent integrated smoke control systems, and limited capacity to support current and future tenant operational demands. The work is characterized by significant operational, phasing, and coordination complexity that requires advanced planning, sequencing, and careful integration with ongoing airport operations to minimize disruption.

The document does not specify detailed pricing terms, set-aside provisions, response deadlines, or contract term lengths in the information provided. Mortenson Construction, located at 10230 NE Points Drive, Suite 300, Kirkland, Washington 98033, serves as the primary GC/CM responsible for executing this multi-phase infrastructure renewal program. The project reflects a strategic capital investment in critical airport infrastructure necessary to maintain operational reliability and accommodate future growth at a major commercial aviation hub.
