SUBJECT:  SEA Load Dock Access Control N04456 (C801357) – Construction Authorization 
Amount of this request:                 $325,000 
Total estimated project cost:            $405,000 

ACTION REQUESTED 
Requesting Commission authorization for the Executive Director to (1) proceed with construction
of the SEA Load Dock Access Control N04456 project, and (2) use Port crews, as well as small
works on-call contracts to perform construction work for the project.  This amount of this
authorization request is for $325,000. The total estimated project cost is $405,000. 
EXECUTIVE SUMMARY 
This request is to utilize Port of Seattle construction crews and small works on-call contracts to
replace three doors to enhance security at the Seattle-Tacoma Airport Load Dock. A substantial
portion of the project is installing the new infrastructure required to add security systems to the
doors. 
JUSTIFICATION 
Seattle-Tacoma International Airport (STIA) has been auditing access points airport wide to
identify any deficiencies in the security and access to secured areas, leaving them vulnerable to
potential  unauthorized  access.  These  doors  have  been  identified  as  needing  security
enhancements due to their access to the Airfield, secure concourse areas, and operationally
essential mechanical equipment.  Keys or cipher lock access are insufficient and do not provide
the ability to monitor and control the room’s access or door status.
This project will increase security measures to meet current Port standards by installing multifactor
authentication (MFA) access control devices, video surveillance cameras, associated
wiring, and infrastructure equipment.

Meeting Date: March 14, 2023 
Diversity in Contracting 
This project will utilize small works on call Contracts that were previously bid and executed, along
with port PCS crews to perform the construction. Equipment purchased will be specialized to
match existing access control system components and will not have flexibility in suppliers.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Status Quo. Do not proceed with the project. 
Cost Implications: Expense approximately $80,000 for design costs. 
Pros: 
(1)   Delays or defers capital investment. 
Cons: 
(1)   Security  of  these  rooms  remains  at  current  levels  with  no  reduction  in  risk  of
unauthorized access. 
(2)   Potential for an additional increase in costs for materials, labor, and/or inflation. 
This is not the recommended alternative.

Alternative 2 – Add Access Control to Load Dock Doors 
Cost Implications: 
Pros: 
(1)   Brings the security access of these sensitive rooms to current Port standards. 
(2)   Reduces the potential risk of unauthorized access to secured areas and mechanical
equipment. 
(3)   Provides the owners of these rooms the ability to remotely monitor room and door
status. 
(4)   Provides better flexibility to control who has access to these sensitive rooms. 
Cons: 
(1)   Higher Capital Cost. 
This is the recommended alternative.
