SUBJECT:  North Employee Parking Lot (NEPL) Improvement Project (CIP #C800957) - Phase 1
Design and Construction 
Amount of this request:                 $570,000 
Total estimated project cost:            $615,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director  to (1) prepare design and
construction bid documents; and (2) advertise and award a major public works contract for
Phase 1 of the North Employee Parking Lot (NEPL) Improvements project at Seattle-Tacoma
International Airport. This request is for both design and construction and is for  an amount of
$570,000 for a total Phase 1 estimated project cost of $615,000. 
EXECUTIVE SUMMARY 
This project will improve basic lot operations and address pavement and infrastructure
rehabilitation. The project will be delivered in two phases. Phase 1 will upgrade existing
facilities and systems to meet standards and support existing operations and customer service
objectives. This  includes upgrades to the existing bus driver and supervisor facilities, a minor
rehabilitation of the bus shelter restrooms, replacing an inoperable entry gate, updating the
facility  monument  sign,  upgrading  the  customer  service  intercom,  and  adding  additional
electric  vehicle  charging  stations.  Design  and  construction  funding  are  being  requested
concurrently to accelerate delivery of these needed Phase 1 improvements.  Phase 2 will be
pursued as a separate effort to rehabilitate or replace failing areas of pavement, seal coat and
restripe the entire lot, and replace the sub-grade water and sanitary sewer piping within NEPL.
Phase 2 is not included with this request. 
This project was included in the 2018 - 2022 capital budget and plan of finance with a budget of
$6.635 million. 
JUSTIFICATION 
This project supports the following Century Agenda strategic goals and objectives:

Meeting Date: October 9, 2018 
1)  Advance this region as a leading tourism destination and business gateway by meeting
the region's air transportation needs at the Airport for the next 25 years. 
2)  Be the greenest and most energy efficient port in North America by reducing air
pollutants and carbon emissions. 
3) Supports the Port's Diversity in Contracting (DC) program efforts and will include WMBE
aspirational goals associated with this project. 
The NEPL supports the employee parking needs for Airport employees and is in need of
targeted renovation and updates since it is 20 years old. The lot is effectively operating at 96%
capacity on a daily basis. Updating this facility and expanding electric vehicle parking will
support the Century agenda strategies and objectives. 
DETAILS 
Phase 1 of the NEPL Improvements project will address several operational requirements that
have arisen as lot use has reached capacity. Additional bus runs to address the heightened use 
have led to more Port bus drivers operating through the lot, requiring an operations supervisor
to be on site to oversee busing activities. Restroom facilities have been well maintained, but
fixtures and counters are showing signs of heavy use and wear. Emergency vehicle and bus
access is reduced because one of the three access gates is no longer operational and is
currently wired closed. The current intercom system only runs to the guard shack, which is not
always manned, and needs to be extended to the bus supervisor's work station so that
customer service can be improved. NEPL currently operates eight electric vehicle charging
stations, and this project would add two more to locations that were pre-wired for them. The
facility monument sign at the front gate does not have the facility address on it, as required by
fire code, and needs to be updated. 
This request includes both design and construction for Phase 1.  Phase 2 is not included with
this request but staff expects to return to Commission for Phase 2 authorization in Q2 2019. 
The scope and budget for the Phase 2 portion of the project are currently undergoing a detailed 
review.
Scope of Work 
The first phase of the NEPL Improvements project would: 
(1) Remodel bus shelter restrooms to maintain public health and improve the customer
experience 
(2) Update entry monument sign would meet fire code requirements; a life safety issue 
(3) Construct permanent driver and supervisor break, office, and meeting rooms for
better employee relations and efficiency 
(4) Install two electric vehicle chargers to meet increased charging station demand

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Status Quo  No upgrades or improvements will be made 
Cost Implications: $0 
Pros: 
(1) No additional cost to the Port with no upgrades or improvements being completed 
Cons: 
(1) Employee parking will continue to operate with failing and outdated facilities and
systems that do not meet standards or support customer service objectives. 
(2) Electric vehicle charging capacity at NEPL is not meeting demand and additional
chargers are needed 

This is not the recommended alternative. 
Alternative 2  Construct the entire project in one phase 
Cost Implications: Up to $9,109,000 
Pros: 
(1) Employee parking will utilize upgraded facilities and systems that meet standards and
support their operations and customer service objectives 
(2) Completes both phases of work as one construction effort likely resulting in a lower
overall project cost 
(3) Installs two electric vehicle chargers to meet increased charging station demand
