DATE:    July 31, 2017 
TO:     Dave Soike, Interim Executive Director 
FROM:   Wayne Grotheer, Director, Aviation Project Management Group 
Jeffrey Brown, Director, Aviation Facilities and Capital Program 
SUBJECT:  Wi-Fi Enhancements Phase 2 (CIP #C800585) 
Amount of this request:          $1,491,000 
Total estimated project cost:      $10,676,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) advertise and execute
contracts for the second phase of construction of the Wi-Fi Enhancement Project at Seattle-
Tacoma International Airport in an amount not to exceed $1,491,000 of a total estimated
project cost of $10,676,000; (2) amend the Infrastructure Design Services for Wi-Fi and Video
Surveillance  System (VSS)  Enhancements Projects service agreement for an additional
$200,000, for a new contract total of $2,700,000; and (3) use port crews and small works
contracts in conjunction with major works contracts to aid in the completion of the project.
EXECUTIVE SUMMARY 
This request provides for the construction of the second phase of Wi-Fi enhancements that will
provide improvements to the Gina Marie Lindsey Arrivals Hall, Baggage Claim, the baggage
make-up areas, the interior of the South Satellite, and the Satellite Transit System Platforms.
The first phase of this project, authorized in May of 2016, is providing Wi-Fi improvements to
the Ramp (and where needed Concourse levels) of Concourses A, B, C and D, the Ramp level of
the South Satellite, as well as the Main Terminal Ticketing level and the security checkpoints. 
JUSTIFICATION 
The overall Wi-Fi Enhancement project will provide up to 200% increase in the coverage and
number of access points on concourse levels, up to tenfold increase in bandwidth, and support
for newer devices by supporting today's technology on wirelessprotocols. Surveys conducted
with enplaning passengers clearly demonstrate the desire for high performance and free Wi-Fi
in the terminal. We've also received very favorable comments from social media posts on our
most recent Wi-Fi upgrades.

Meeting Date: August 8, 2017 
Throughout the Wi-Fi project, there are interior and exterior high speed devices being targeted.
The interior high-speed wireless access will provide much improved Internet access for
passengers and tenants in public areas of the Airport. The exterior devices will support airport,
airline, and tenant operations outside the facility on the ramp level at passenger loading
bridges. 
In public areas, mobile devices will connect to new Wi-Fi access points installed inside the
facility, which replace the existing Distributed Antenna System (DAS) Wi-Fi access points in the
terminal and concourses. The new Wi-Fi access points will enable higher bandwidth, support
more connected devices and comply with the latest Wi-Fi standards used by today's mobile
devices. The density of wireless access point coverage will significantly reduce connection
problems while providing higher download and upload speeds for passengers and airline staff. 
The "ramplevel wireless network" will be accessed by both handheld and vehicle-mounted
mobile devices and by new aircraft avionics systems. The design of the enhanced Wi-Fi network
will support Virtual Private Networks (VPNs) that will be configured for secure Airport, airline,
and tenant operations.
The second phase of the Wi-Fi Enhancement Project is tasked with completing the intended
coverage and capacity benchmarks across the Airport as put forth at the beginning of the
project. Without the second phase, the coverage across the airport will be incomplete and the
passenger experience will suffer. 
DETAILS 
The first phase of the Wi-Fi project received construction bids that were less than estimated. It
is assumed that a portion of this savings is due to the quality of the detailed design provided by
the design team. However, due to the complexity of the design in other areas, the original
design authorization will be inadequate to fully complete the remaining scope of the project. 
As a result, the Infrastructure Design Services for Wi-Fi and VSS Enhancements Projects service
agreement needs to be amended by an additional $200,000 for additional Wi-Fi design services,
for a new amended total of $2.7 million. In accordance with RCW 53.19.060 (2), this notifies
Commission that the total contract has been increased by more than 50% of the original
contract value.  The contract will be placed at the bid desk and be available for public
inspection. 
In 2016, the Commission authorized an increase to the service agreement from $900,000 to a
new total of $2 million for additional design services. In May 2017, Commission authorized an
additional increase of $500,000 for additional design support of the VSS system, for an 
amended total of $2.5 million, which increased the agreement by more than 50 percent of the
original value. Commission was notified of this increase and the contract was made available
for public inspection.

Scope of Work 
When the second phase of this project is complete, the Airport will have an enhanced Wi-Fi
system that will provide high-speed Internet access for mobile device users throughout the
entire interior and exterior of the airport aside from the North Satellite.
The ramp Wi-Fi system will be supported by the installation of weather tight micro-distribution
cabinets, which provide network backbone connectivity for the ramp Wi-Fi access points. These
will be installed on the exterior of the building at the ramp level of concourses and South
Satellite mounted on or in close proximity to passenger loading bridges. Micro-distribution
cabinets will provide the infrastructure necessary for the ramp wireless network as well as
other anticipated network connectivity. Micro-distribution cabinets will also provide the
required network connectivity for Wi-Fi improvements to the interior of Concourse C hold
rooms. 
Certain areas and functionality are not included within the above scope of work. While Wi-Fi 
access points will be installed in hold rooms and aircraft gate areas, this project will not install
them within concession lease spaces which were included in the Airport's Dining and Retail
program and associated projects. 
Small Business 
As part of the scope of work, the use of small works contacts in conjunction with this major
works project, promotes strong small business participation.
In an effort to maximize small and diverse (MWBE) business interest, project managers have
partnered with the Port's Small Business Group to conduct outreach and training efforts
through PortGen activities. Certified small business requirements will be administered during
the time of solicitation.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 Do not proceed with phase 2 construction. 
Cost Implications: $0 
Pros: 
(1)   Costs to deploy new networks could be passed to the tenants. 
(2)   Some Wi-Fi coverage would remain via the existing DAS. 
Cons: 
(1)   Costs have already been incurred for design. 
(2)   There will be areas that do not benefit from upgraded Wi-Fi thus encouraging tenants
to implement their own systems. This will create multiple different Wi-Fi networks
across the airport. 
(3)   The passenger experience will continue to suffer. 
This is not the recommended alternative. 
Alternative 2  Proceed with construction of portions of phase 2, but do not increase the design
budget and therefore do not complete the remaining planned Wi-Fi installation. 
Cost Implications: $1,291,000 
Pros: 
(1)   Provides a high level of service across interior areas included in the scope of this
project 
(2)   The airport will have a single, continuous, high speed network across the majority of
the Airport Terminal area 
Cons: 
(1)   The design scope will decrease; therefore, some areas would not receive high speed
Wi-Fi upgrades. 
This is not the recommended alternative. 
Alternative 3  Proceed with construction of phase 2 and reallocate construction bid savings to
the design budget. 
Cost Implications: $1,491,000 
Pros: 
(1)   Provides a high level of service across all areas included in the scope of this project 
(2)   The airport will have a single, continuous, high speed network across the majority of
areas with passengers 
(3)   The originally promised level of service will be achieved for ramp Wi-Fi
