SUBJECT:  Surface Area Management Project Additional Authorization (CIP #800650 )
Amount of this request:               $2,614,000 
Total estimated project cost:         $18,479,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to 1) increase the authorized
project budget for the Surface Area Management project by $2,614,000 for a total budget of
$18,479,000; and 2) include and use a Project Labor Agreement.
EXECUTIVE SUMMARY
The Surface Area Management (SAM) project, first authorized in June 2019, has implemented a
system to improve airfield situational awareness and provide forensic and analytic information
on airfield operations at Seattle-Tacoma International Airport (SEA). The system provides
information to improve aircraft flow and gate docking efficiencies, reduce aircraft holds, and
support safety initiatives by providing more detailed information on incident causes and
contributing factors. Integrating with several Port and external data feeds, the system provides
a real-time, actionable picture of operations that is invaluable to Airport Operations, emergency
response, security, and our airline partners. 
The system is being implemented in multiple phases and portions are now used by Port staff,
Federal Aviation Administration (FAA), and Airlines. The first three phases deployed the core
system, video analytics capabilities, integration with other Port systems, and vehicle and
equipment tracking. In parallel to the delivery of these phases, the project team progressed the
design work for phase four, the installation of sensors and cameras used by the new system to
provide more detailed situational awareness on the airfield. The first three phases of the project
have been completed using the Job Order Contract (JOC) and staff have proceeded with the
procurement process to deliver the final phase of the work via a major public works contract. 
The Port opened bids for the major public works contract phase of the project in March 2024.
Only one bidder proposed on the project and the bid total is 47% above the engineer’s estimate.

Meeting Date: June 25, 2024 
After the bid opening, staff took the time to evaluate other delivery methods/alternatives to
complete the work cost effectively and efficiently.  The preferred alternative is to award the
project to the sole bidder and increase the project budget by $2,614,000.
JUSTIFICATION
The SAM system provides a holistic view or understanding of underlying reasons or root causes
for delays, bottlenecks, or deficiencies and improve overall airfield efficiency and safety at the
Airport. Additional funding through this request will allow the system to be constructed as
designed providing the greatest opportunity to provide this holistic view.
Diversity in Contracting 
The project team has worked with the Diversity in Contracting Department to establish a 10% 
women- and minority-owned business enterprise (WMBE) aspirational goal for this construction
contract. 
DETAILS 
This system is comprised of sensors and cameras throughout the airfield which will provide
forensic and analytical information on airfield operations at SEA. The intent of this project is to
utilize system data to better determine root causes associated with delays, bottlenecks and
deficiencies which will guide decisions to improve overall airfield efficiency and safety.
Scope of Work
The Phase 4 project scope of work includes sensor and camera installation at various locations in
the airfield to improve identification of targets for situational awareness and provide gate turn
monitoring at all gates. The scope also includes the setup of the all the required Power and
Communication Infrastructure for the sensors and cameras.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Utilize the JOC contractor to complete the work at 21 locations.
Cost Implications: ~$7,700,000 in additional funding. 
Pros:
(1)   JOC contractor has completed 9 locations and has implemented lessons learned. 
(2)   JOC contract is executed, and work order(s) can proceed as capacity allows. 
Cons:
(1)   Highest cost alternative 
(2)   JOC construction completion anticipated in July 2026 which is the longest path to
complete the time sensitive scope of work. 
(3)   JOC capacity likely will be a challenge.
(4)   Future JOC contracts may not be awarded to the current JOC contractor, losing lessons
learned and decreasing efficiencies. 
This is not the recommended alternative. 
Alternative 2 – Repackage the design-bid-build contract and re-bid the project.
Cost Implications: ~$6,050,000 in additional funding. 
Pros:
(1)   Re-bid documents would provide more detailed information to reduce unknown risks
to bidders. 
(2)   Opportunity for additional contractor outreach. 
Cons:
(1)   No guarantee the re-bid package will attract more bidders. 
(2)   Potential for bid(s) to be higher than the current sole low-bidder. 
(3)   Major works construction completion anticipated in June 2026.
(4)   May require additional budget increases.
This is not the recommended alternative. 
Alternative 3 – Award Major Works contract to low bidder.
Cost Implications: ~$5,600,000

Annual Budget Status and Source of Funds 
This project, C800650 was included in the 2024-2028 capital budget and plan of finance for
$13,001,000. The capital budget increase of $5,078,000 was transferred from the Aeronautical
Allowance C800753 resulting in no net change to the Aviation Division capital budget. The
funding source would be the Airport Development Fund and revenue bonds.

Future Revenues and Expenses (Total cost of ownership) 
Previously authorized annual recurring maintenance and license costs for this system, estimated
at $1,620,000 are budgeted in the Aviation Operations and Aviation Maintenance operating
budgets. 
ADDITIONAL BACKGROUND 
Since the deployment of phase 1 of the project, the Port and its partners have realized several
benefits from using the new system. 
(1)      Alaska Airlines leveraged information from the new system and implemented a change to
its operations that that resulted in reduction of wait time for gates upon arrival.
(2)      Ramp Tower and FAA coordination significantly improved coordination during impacts of
the 2021 Airport Improvement Project (AIP) work and International Arrivals Facility (IAF)
construction taxi lane closures 
(3)      Sixty-seven (67) gates are currently under turn monitoring surveillance providing time
stamps of up to 36 critical milestones throughout the progression of a turn which
establishes a record to gauge vendor performance and predict off-block times.
