SUBJECT:  2021 Garage Fire Repair (Expense)

ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) complete design and (2)
utilize Port crews and small works contracts to complete repairs associated with the 2021 Garage
Fire Repairs project at Seattle-Tacoma International Airport. The amount being requested under
this authorization is $750,000 for a total estimated project cost of $900,000. 
SUMMARY 
On December 3, 2021, a multi-vehicle fire in the main parking garage damaged existing lighting
systems, signage, and structural concrete. The fire was on the fourth floor in the North end of
the Garage, but the damage has closed portions of the third, fourth, and fifth floors until repairs
can be completed. Currently, the third floor has been reopened, 90 stalls are closed on the fourth
floor, and 142 stalls are closed on the fifth floor. This represents approximately two percent of
the total parking capacity in the Garage. 
This project will be split into two phases to accelerate the repair schedule. Phase one will include
the electrical repairs to the lighting system and is anticipated to be complete by Q3 2022. Once
completed the majority of the fourth floor will be returned to parking operations. Phase two will
include the structural concrete repairs and is anticipated to be complete by Q2 2023. Upon
completion of Phase 2, the remaining parking stalls that were closed will be returned to parking
operations. The full scope of the structural concrete repairs is being evaluated currently as part
of a damage assessment. For the damage assessment, the Port is utilizing an existing indefinite
delivery indefinite quantity (IDIQ) contract which has a WMBE goal of 16%. Depending upon the
results, additional future commission authorization and a longer completion schedule may be
required.
