AGENDA MEMORANDUM                Item No.       6e 
ACTION ITEM                   Date of Meeting    January 30, 2018 
DATE:    January 22, 2017 
TO:     Dave Soike, Interim Executive Director 
FROM:   Wendy Reiter, Director Aviation Security 
Wayne Grotheer, Director Aviation Project Management 
SUBJECT:  Airport Terminal Safety and Security Enhancements (CIP #C800862) 
Amount of this request:          $1,481,000 
Total estimated project cost:      $12,941,000 
ACTION REQUESTED 
Request Commission authorizations for the Executive Director to (1) proceed with the design
and preparation of contract bid documents for Phase II of the Airport Terminal Safety and
Security Enhancements (TSE) project for $1,481,000 for a revised total project authorization of
$7,789,000 for both phases. 
EXECUTIVE SUMMARY 
Phase II will install: 1) additional security and safety features in the Main Terminal and Parking
Garage; and 2) access ramps along both curbsides to meet current Americans withDisabilities 
Act (ADA) standards. An existing Architect Services Indefinite Delivery/ Indefinite Quantity
(IDIQ) service agreement will be utilized to direct the design services. Staff will return later in
2018 for authorization to advertise, award and execute the construction contract for Phase II. 
Phase I of the TSE project was previously authorized by the Commission on October 24, 2017. 
JUSTIFICATION 
Proceeding with Phase II of the TSE program will continue to keep the occupants of the Main
Terminal safe. Installing ADA compliant access improvements for disabled travelers on both the
Arrivals and Departures curbsides as part of the security work ensures that the design is
compatible. These improvements support the Port's goal of making SeaTac the most accessible
airport in the nation for people with disabilities. 
DETAILS 
Current ADA standards require the provision of  one accessible loading zone  for  every
continuous 100 linear feet, or fraction thereof, of curbside. Each accessible loading zone shall
be designated with signage along both curbsides. Accessible loading areas on the drives are

critical, as confirmed by staff, who recommend that ADA accessible ramps be added and
incorporated into the  security project, especially since the installation of both are so closely
tied together. 
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 twelve on the Arrivals curbside, and from three to twelve on the
Departures curbside. Security improvements will also be installed in the Main Garage at the
entrance to each of the six sky bridges. 
This scope of work entails opportunities for small and disadvantaged businesses. Project staff is
working with the Economic Development Division  Small Business Group, to help identify and
promote those opportunities within the scope of work.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Three options were considered as follows: 
Alternative 1  Status Quo Do not proceed with security or ADA access improvements 
Cost Implications: $ 0 
Pros: 
(1)   No capital investment 
Cons: 
(1)   Does not increase the safety and security of the Main Terminal. 
(2)   Does not enhance ADA accessibility. 
This is not the recommended alternative.

Meeting Date: January 30, 2018 
Alternative 2  Proceed with the security improvements only 
Cost Implications: $5,559,000 
Pros: 
(1)   Proceeding with the security improvements will increase the safety and security of the
Main Terminal. 
Cons: 
(1)   Requires a capital Investment of $5,559,000. 
(2)   Does not take advantage of an opportunity to install ADA access ramps with the
installation of security improvements in order to reduce the total costs of both
projects, avoid removing and reinstalling recently complete work if work is done
separately, and minimize construction impacts on the traveling public 
This is not the recommended alternative. 
Alternative 3 Proceed with security and ADA access improvements 
Cost Implications: $6,653,000 
Pros: 
(1)   Proceeding with security and ADA access improvements under one project saves
approximately $260,000 and reduces the overall construction impacts to the traveling
public. 
(2)   Proceeding with security improvements will increase the safety and security of the
Main Terminal. 
(3)   The Arrivals and Departures curbsides will become compliant  with current  ADA
standards sooner than currently planned and helps expedite achieving the Port goal of
making the Airport the most accessible airport for people with disabilities in the
nation. 
Cons: 
(1)   Requires a greater capital investment of $6,653,000 
This is the recommended alternative.

Annual Budget Status and Source of Funds 
This project was included in the 2018  2022 capital budget and plan of finance with a budget
of $9,854,000 million. The cost increase is due to adding scope for the sky bridges (Phase I),
and adding the ADA access improvements (Phase II). The budget increase will be transferred
from the Aeronautical Allowance CIP (C800753) resulting in no net change to the Aviation
capital budget. The funding source will be the Airport Development Fund and future shortterm
revenue bonds. This project was approved by the airlines via the November 2017
Majority-in-Interest vote.

CPE Impact                $0.07 in 2019 
Future Revenues and Expenses (Total cost of ownership) 
Port staff does not anticipate a significant change in the on-going operation and maintenance
costs associated with these improvements since preventative maintenance is not performed on
the security and ADA access improvements. Additional costs will be incurred if the
improvements are damaged and need to be replaced.
