SUBJECT:  Authorization for Alternative Project Delivery Terminal Security Enhancements
(CIP #C800862) 
Amount of this request:               $1,500,000 
Total estimated project cost:         $21,400,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to: 1) utilize the traditional
design-build contracting methodology, 2) advertise and award the design-build contract, and 3)
complete final design and construct Phase II of the Terminal Security Enhancements project at
Seattle-Tacoma International Airport  (Airport).  An additional budget in the amount of
$1,500,000 is included in the request for a total estimated cost of $21,40,000.
EXECUTIVE SUMMARY 
The Terminal Security Enhancements (TSE) Phase II project is intended to improve passenger
safety with the installation of structural bollards along the airport's arrivals and departures
curbsides, the courtesy vehicle plaza, and the pedestrian sky bridge entrances in the main
garage. The installation of these bollards has been identified as a key component of the overall
comprehensive security program at the airport. The project will also complete the Americans 
with Disabilities Act (ADA) access improvements along the arrivals and departures curbsides. 
The project was advertised in 2019 with competitive bids coming in well above budget. To 
reduce costs, Port staff determined to split the procurement of the bollard materials from the
construction contract, as an owner-furnished contractor-installed material. An evaluation of the 
bollard contract was performed, and construction bids were opened with results well within the
authorized budget. The bollard procurement was then protested by multiple vendors. Following 
an administrative hearing for the protests, the bollard procurement was cancelled. The Port
also cancelled the major construction procurement because of the interdependency of the
bollards purchase with the install contract. The project team reassessed the project and given
the complexity of the project and how the bollards are structurally connected to our existing

facilities, concluded that the design-build alternative delivery method is the best option for
delivering the project scope while addressing procurement and construction risks. 
This project was initially approved by a majority-in-interest (MII) vote of the signatory airlines
per the Signatory Lease and Operating Agreement (SLOA). The project increase of $1,500,000
will not require an additional MII vote, since the increase is less than the 10% allowed per the 
SLOA. 
JUSTIFICATION 
The Phase II of the TSE program is necessary as it will provide security improvements,
accessibility improvements as recommended by the Accessibility Study completed by the Open
Doors Organization (ODO), and corrective actions per an agreement with the FAA. These
improvements support the Port's goal of making SEA the most accessible airport in the nation
for people with disabilities and provide a safe environment for SEA's passengers, staff and
visitors. 
Diversity in Contracting 
Project staff worked with the Diversity in Contracting Department and have established an
eight percent (8%) Women- and Minority-Owned Business Enterprise (WMBE) aspirational goal
for the project  supporting the Port's objective of increasing WMBE participation in Port
contracts. 
DETAILS 
On July 23, 2019, the project was advertised for construction bids with an engineer's estimate
in the amount of $8,568,103 for a total estimated project cost of $16,116,000. The Port
cancelled the procurement because all bids significantly exceeded the engineers estimate and
the Port determined it was in our best interest to re-design the project and delivery method.
Based upon the bids received the total estimated project cost was $24,000,000. 
On January 28, 2020, the Commission authorized the procurement of the structural bollards as
owner procured materials to increase competition resulting in a lower bollard cost. A total of
five proposals were received, ranging in cost from $1.5 to $2.9 million. A notice of intent to
award was issued on August 3, 2020. 
After issuing the notice of intent to award for the bollard procurement, multiple vendors
protested the selection  in early September. Following an administrative hearing for the
protests, the bollard procurement was cancelled. As a result of this decision, the dependent
major works construction procurement was also cancelled. Bids had just been opened for the
major works construction contract where the low apparent bidder was 34% below the
engineer's estimate.

Meeting Date: December 15, 2020 
Additionally, the Federal Aviation Administration (FAA) received a complaint regarding the lack
of accessibility improvements on the curbside and has requested that the airport remedy the
situation. FAA has been notified of the delayed project schedule and understands the decision
to cancel the contracts. 
Scope of Work 
The project will install security and ADA access improvements at the entrances to the main
terminal from the arrivals and departures curbsides. The number of accessible loading zones
will increase from two to 12 on the arrival's curbside, and from three to 12 on the departure's
curbside. Security improvements will also be installed in the Main Garage at the entrance to
each of the six pedestrian sky bridges and along the third-floor courtesy vehicle plaza.

The project will be installing new roadway directional signing that will be replace existing
signage attached to the pedestrian sky bridges. Currently , the airport receives revenue from
advertising signage that is placed on the exterior of the pedestrian sky bridges. The new
roadway direction signage will be slightly taller than the existing signage and may impact the
revenue potential from the advertising signage.
