DATE: July 30, 2021
TO: Stephen P. Metruck, Executive Director
FROM: Matt Breed, Chief Information Officer, Information & Communication Technology
Jim Dawson, Dir. Infrastructure Services, Information & Communication Technology
SUBJECT: Port Headquarters WIFI Replacement (CIP #C801063)
Amount of this request: $820,000
Total estimated project cost: $2,500,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to (1) proceed with the Wireless
Network (WIFI) Replacement project; (2) prepare design and construction bid documents for the
replacement of WIFI technology and supporting equipment at the Port of Seattle Headquarters
(P69); and (3) procure required hardware, vendor services, licensing, and maintenance services
in support of WIFI and network services at P69. The amount of this request is $820,000. The total
estimated project cost is $2,500,000.
EXECUTIVE SUMMARY
This project will replace the current P69 wireless network to ensure continuity of WIFI service,
deploy technology that adheres to Port security protocols, and provide full coverage of work and
public spaces. The Port WIFI is used extensively throughout P69 by employees, customers, and
visitors to access internal Port systems or external internet. The network, deployed over a decade
ago, is at end-of-life, no longer receives security updates, and doesn't provide the coverage or
bandwidth needed to meet modern connectivity requirements.
This authorization includes the design of electrical and communication infrastructure to support
new wireless access points and the procurement of equipment to minimize schedule risks from
long-lead time items that will be installed by the construction contractor as well as Port labor
respectively. Authorization for construction will be sought in a subsequent request.

Template revised January 10, 2019.

COMMISSION AGENDA Action Item No. __8c__ Page 2 of 4
Meeting Date: August 10, 2021
The capital project is included in the 2021-2025 capital budget and plan of finance for $2,500,000.
Recurring costs estimated at $11,600 per year will be budgeted in the ICT operating budget
beginning in 2022.
JUSTIFICATION
Replacing end-of-life hardware supports the Century Agenda goal of being a highly effective
public agency by proactively maintaining technology critical for Port operations.
(1) The current wireless infrastructure is old, at risk of failure, and most components no longer

(2) Requirements for wireless access have changed over the last decade and the current wireless
infrastructure is not able to accommodate the number and types of devices used by
employees and visitors, as well as the bandwidth required for more sophisticated
applications.
(3) As our workforce becomes more mobile, expectations for connectivity throughout P69
increase. The upgraded WIFI will include better coverage in areas without adequate
connectivity.
Diversity in Contracting
Design work is being performed in-house. Project staff will work with the Diversity in Contracting
Department to identify WMBE opportunities.
DETAILS
This project will replace the current WIFI at P69 with better coverage and bandwidth to meet
requirements for modern and emerging technology, install equipment that adheres to the Port's
security protocols, and minimize the risk of failure due to age. Following is the scope of work for
this authorization.
Scope of Work
(1) Utilize existing IDIQ for a site survey to determine best wireless access point locations to
provide full coverage at P69.
(2) Utilize in-house communication infrastructure Design Engineer to develop designs for
installation of WIFI equipment and electrical and communication infrastructure.
(3) Procure WIFI equipment as needed to meet schedule expectations.
(4) Installation of communication room equipment by Port labor.
There are other Port sites with aging or insufficient wireless connectivity that may require
attention during this project. They will be addressed separately with operating funds or small
capital projects. More comprehensive needs at other sites will be evaluated for future projects.

DATE: July 7, 2021
TO: Stephen P. Metruck, Executive Director
FROM: Eileen Francisco, Acting Director, Aviation Facilities and Capital Programs
Wayne Grotheer, Director, Aviation Project Management
SUBJECT: Airfield Utility Improvements (AUI) Design (CIP #C801177)
Amount of this request: $6,300,000
Total estimated project cost: $46,200,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to (1) complete design and
prepare construction documents for the Airfield Utilities Infrastructure (AUI) project (CIP
C801177) at Seattle-Tacoma International Airport (SEA) and (2) enter into reimbursable
agreements with the Federal Aviation Administration. This design authorization is for an
amount of $6,300,000 out of a total estimated project cost of $46,200,000.
EXECUTIVE SUMMARY
The Facilities and Infrastructure (F&I) group at SEA have identified a variety of capital
improvements required to replace and amend aging, failing, and over-capacity utility systems
serving the existing terminal and apron areas. These utilities are located on the airside of the
terminal and include sanitary sewer, domestic water, power, communications, and the
industrial wastewater system (IWS). This AUI project will minimize operational impacts, achieve
soft cost efficiencies, and enhance airfield construction safety management by sequencing the
work to align with two existing programs: The Airfield Pavement and Supporting Infrastructure
Replacement Program and the South Satellite Renovation Program. Construction of the utility
improvements will begin in 2023 and conclude in 2025.
JUSTIFICATION
The Airfield Sanitary Sewer trunk-line serving the terminal and the South Satellite (SSAT) is in
poor condition. F&I has identified deteriorating joints, sagging pipe and structural damage as
part of their Closed-Circuit Television (CCTV) pipe condition assessment program. Now over 60
years old, this sewer trunkline is also exceeding current conveyance capacity and cannot take

Template revised January 10, 2019.

COMMISSION AGENDA Action Item No. _8d_ Page 2 of 6
Meeting Date: August 10, 2021
additional sewer loads from the main terminal. The new sewer trunk-line will also support the
C1 Building expansion and South Satellite renovation.
The existing cast iron water main that runs underneath Concourse B was built in the 1960's and
has exceeded its 50-year life span resulting in a high risk of failure. This water main is serving
both domestic and fire for Concourse B and the SSAT. Concurrent to replacement of the
sanitary sewer trunk line described above, the AUI project will install a new ductile iron water
main outside of the footprint of Concourse B allowing for access for maintenance or repairs.
A recent CCTV condition assessment of the IWS pipe revealed that portions of the system in the
vicinity of the sewer and waterline work are also in poor condition and need to be relined or
replaced to prevent failures and impacts to operations, as well as prevent infiltration of
contaminated runoff.
There is a need for a power and communication ductbank that will run from the SSAT power
station to the NSAT power station to create redundancy to the airport's terminals. These
ductbanks are part of the Utility Master Plan. Where the AUI project is removing pavement and
impacting operations to install the sewer and waterlines, it will use the opportunity to install
significant portions of this ductbank system.
This project contributes to the Port's Century Agenda goal to meet the region's air
transportation needs at Sea-Tac Airport for the next 25 years. It supports current and future
Airport capacity by improving the efficiency of utility systems and extends their useful life.
Diversity in Contracting
Project staff is working with the Diversity in Contracting Department to include inclusion plans
and the establishment of women and minority business enterprise (WMBE) aspirational goals
for this project.
DETAILS
The project involves installing new ductile iron sewer pipe to replace under capacity, failing and
aging sewer pipe; installing new ductile iron water pipe to replace aging cast iron water pipe
that is currently located within the footprint of Concourse B; renewing aging and damaged IWS
pipe through a combination of trenchless pipe relining and replacement with new pipe where
pipe damage prohibits use of lining techniques; finally, installing new concrete-encased power
and communication ductbanks running roughly parallel with the SS trunkline from the SSAT to
roughly 100 feet past the north end of Concourse C. The excavation and replacement of existing
pavements that are associated with the utility scope described in this section are part of the
project scope.

Financial Analysis and Summary
Project cost for analysis $46,200,000
Business Unit (BU) Terminal Building 97% and IWS 3%
Effect on business performance (NOI after NOI after depreciation will increase due to
depreciation) inclusion of capital (and operating) costs in
airline rate base
IRR/NPV (if relevant) N/A
CPE Impact $.13 in 2026
Future Revenues and Expenses (Total cost of ownership)
This project will not have an impact on annual Aviation Maintenance operating and
maintenance (O&M) costs for mechanical or electrical systems and may lead to a reduction in
the amount of time currently spent by the field crew on pipe inspections due to the current
condition of the water and sewer systems. After implementing the project, the improved
portions of the water and sewer systems will have a renewed 50-year asset life and a greatly
reduced risk of failures, emergency repair and maintenance work, and impacts to operations.

Action Requested
Request Commission authorization for the Executive Director to
(1) complete design and prepare construction documents for the
Airfield Utilities Infrastructure (AUI) project (CIP C801177) at
Seattle-Tacoma International Airport (SEA) and (2) enter into
reimbursable agreements with the Federal Aviation
Administration. This design authorization is for an amount of
$6,300,000 out of a total estimated project cost of $46,200,000.

Project Purpose
This Airfield project replaces the 50+ years old, failing and
undersized Sanitary Sewer, Watermain, and Industrial Waste
System (IWS) infrastructure that allow the Main Terminal and
South Satellite to operate. It also adds Power and
Communications pathways to increase resiliency of the
Satellites.
The work will be phased with planned operation outages of
the existing Airfield Pavement Program for years 2023 to 2025.
The work also supports and is critical path for the C1 Building
Expansion and South Satellite Renovation Projects.
