ACTION ITEM 
Date of Meeting     August 6, 2013 
DATE:    July 29, 2013 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:   Ralph Graves, Managing Director, Capital Development Division 
SUBJECT:  Project Labor Agreement Approval for Airfield Projects 
ACTION REQUESTED 
Request Commission authorization to execute project labor agreements (PLAs) for seven
different projects at Seattle-Tacoma International Airport currently in their design phases. The
projects are: Cargo 2 West Hardstand Expansion, Cargo 5 Hardstand, Cargo 6 Enhancements,
2014 Airfield Apron Pavement Replacement Design, North Satellite Transit System Ceiling
Leaks Long-Term Repair, and Vertical Conveyance Modernization Aero Phase 1 and Phase 2.
No funding is associated with this authorization. 
SYNOPSIS 
There are seven projects at the Airport that will be constructed using separate construction
contracts. All of these projects are located on the airfield and could result in significant impacts
to airfield operations. These projects have already received design authorization and would have
schedule impacts  if PLA negotiations were to occur after Commission construction 
authorization. This request will allow PLA negotiations to proceed for these projects and avoid
schedule impacts. The seven projects that comprise the contracts are as follow: 
1)  CIP #C800247 Cargo 2 West Hardstand Expansion. 
2)  CIP #C800254 Cargo 5 Hardstand. 
3)  CIP #C800390 Cargo 6 Enhancements. 
4)  CIP #C102573 2014 Airfield Apron Pavement Replacement Design. 
5)  CIP #C800609 North Satellite Transit System Ceiling Leaks Long-Term Repair. 
6)  CIP #C800251 Vertical Conveyance Modernization Aero Phase 1. 
7)  CIP #C800375 Vertical Conveyance Modernization Aero Phase 2. 
A disruption in the work for these projects could result in impact to both Airport tenants and
patrons. Delays in projects 1-5 listed above could have airfield operations impacts and could also
push work into unfavorable weather, leading to a decrease in both work quality and safety.  The
authorization to proceed with PLA negotiations is not expected to result in additional cost to the 
projects. 
Use of a PLA has typically been authorized in conjunction with the Commission authorization
for advertisement of construction contracts. Port staff have recently expressed concern about

schedule impacts due to the limited time to complete negotiations between authorization and
advertisement of the contract. Accordingly, future PLA authorizations will be requested at the
time of design authorization to minimize impacts to planned construction contract
advertisements. Currently PLA agreements are in place on ten of 46 active Port construction
contracts, all at the airport. 
BACKGROUND 
Cargo 2, 5, 6 
The proposed 2014 Air Cargo Hardstand Improvements construction contract includes the Cargo
2 West Hardstand Expansion (C800247), Cargo 5 Hardstand (C800254), Cargo 6 Enhancements 
(C800390), and part of the Airfield Apron Pavement Replacement (C102573) projects. Projects
for Cargo 2 and Cargo 6 will increase the capacity and efficiency of air freight cargo and allow
two wide-body aircraft to be loaded simultaneously in each location. The Cargo 5 project will
increase the number of remain-overnight parking positions for aircraft. The portion of the apron
pavement replacement under this contract is within the Cargo 6 project area. 
Port staff recommend that the combined 2014 Cargo Projects be a PLA contract to ensure that
the work is done in a single construction season and that partial airfield closures for construction
are minimized. Cargo 5 in particular requires a 30 -day disruption in aircraft flow  while
connecting Taxiway A to the Cargo 5 area; however, a delay could extend this period. There will
be a partial closure of a taxiway and relocation of the service road, and work progress being
disrupted could impact Airport operations. Airfield work is seasonal by nature and a labor
disruption could delay the work into an adverse weather period and create issues with the quality
and level of safety of the work. 
2014 Airfield Apron Pavement Replacement 
In addition to the Cargo 6 area, there will be other sections of the airfield undergoing pavement
replacement as part of the 2014 Airport Improvement Program. This is part of an ongoing
pavement management program to replace aged and distressed pavement and joint sealant in
non-runway areas. 
Port staff recommend that the 2014 Airfield Apron Pavement Replacement be a PLA contract 
due to the sensitive nature of both its location and timeline. Airfield panel and joint seal 
replacement will occur in scattered areas within the Air Operations Area. This will result in some
degree of disruption to operations. A PLA contract will minimize project risk and impact to
Airport operations. There is also a limited construction window  six months  due to visibility
issues that begin to develop on the airfield. 
NSAT STS Ceiling Leak Long-Term Repair 
Pavement at the North Satellite Terminal (NSAT) has failed and allows rain to enter into the
satellite transit station (STS) directly below the failed slab. The NSAT STS Ceiling Leak Long-

Term Repair project (C800609) will replace the concrete slab, adding the necessary
waterproofing and drainage features. 
Port staff recommend that the NSAT STS Ceiling Leak Long Term Repair be a PLA contract 
due to the potential impacts labor dispute delay could have on public safety and Airport
operations. Once the concrete panel has been removed, rainfall could readily infiltrate the
structural slab and enter the STS station, creating a risk for the public and for Port infrastructure.
A PLA would limit the risk of exposure of the public and Port infrastructure to the elements. 
Vertical Conveyance Modernization Aero Phases 1 & 2 
These projects are a part of the Port's modernization program to renew, replace, or construct new
vertical conveyance systems at the Airport and are being completed under two separate contracts.
The conveyances included in the modernization program range from 20 to 40 years in age and
consequently the service duty cycles are often exceeded. This results in frequent breakdowns and
loss of service to critical infrastructure. 
Port staff recommend that the Vertical Conveyance Modernization Aero Phase 1 (C800251) and
Phase 2 (C800375) should be PLA contracts to minimize the down time of the elevators and
escalators and ensure that passenger circulation is not compromised. There are a number of
union contracts expiring in the near future that are involved with these projects and so there is a
potential for a higher likelihood of labor disputes that would delay work. Each project phase
includes one or more elevators at the South Satellite terminal. Because of this, some portion of
the work will take place on and impact the airfield. These projects will coordinate all work with
the other airfield projects, so a delay on these projects could potentially influence another's
schedule. 
PROJECT JUSTIFICATION AND DETAILS 
Specific objectives of entering into PLAs for these seven construction contracts are as follows: 
PLA Objectives 
Maintain each project's schedule due to linkages critical to and integrated into the
program's schedule. 
Meet completion dates of the projects critical to improving the Airport's operational
efficiency and capabilities. 
Minimize impacts to all areas of Airport operations, due to location of the projects. 
Ensure extensive coordination and management between airfield construction projects
(Port, Federal Aviation Administration (FAA), and Air Traffic Control). 
Ensure a skilled, cooperative and stable labor force across every craft on each project to
minimize adverse disruptions to the Airport and airline operations and make the
implementation of the projects a success. 
Minimize impacts to project construction created by occasional unscheduled labor
stoppage events that may occur periodically.

COMMISSION AGENDA

Page 4 of 5 
Ensure uniform working conditions on each project given the close proximity of
construction, Port, airlines, cargo, and, for airfield projects, FAA workers. 
Ensure a safe environment to the traveling public (for vertical conveyance projects) and
employees walking or working on, adjacent to, and possibly through construction work
zones; necessary for maintaining Airport and airline operations. 
Ensure construction continues if jurisdictional issues arise that require resolution
through dispute resolution process or a Department of Labor and Industries (L&I)
determination. 
Ensure labor harmony between union and non-union contractors working adjacent or
side-by-side performing tenant improvements. 
Scope of Work 
Staff will engage in negotiations with the local building and trades unions and enter into PLA 
contracts. 
Schedule 
Negotiations will begin prior to construction authorization from the Commission for any of the
projects included in this memo. 
STRATEGIES AND OBJECTIVES 
Authorization of this request is in line with the Port'sCentury Agenda objectives to meet the
region's air transportation needs for the next 25 years, grow domestic and international passenger 
service; triple air cargo volume, foster regional economic growth, and maintain a high level of
performance. 
TRIPLE BOTTOM LINE 
Economic Development 
The use of PLAs reduces risk in the delivery of projects and potential impacts that could otherwise
result from labor disputes. The listed projects support the Airport's strategy of operating a worldclass
international airport by anticipating and meeting the needs of our tenants, passengers and the
region's economy. 
Community Benefits 
These PLAs support projects that will increase the long-term ability of the Airport to serve a growing
number of both passengers and airlines, thereby supporting the regional economy, customers and the
nearby communities.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1: Do not include PLAs for any of the construction contracts. This would result in the
potential for labor disputes' interrupting work and delaying the projects indefinitely. This is not
the recommended alternative. 
Alternative 2: Each project submits an individual request for authorization of PLA negotiations.
This results in many separate memos and presentations with negotiations taking place after
construction authorization, leading to potential delays in both the project schedule and bidding
period. This is not the recommended alternative. 
Alternative 3: One authorization request to execute a PLA is submitted for all of the projects 
prior to construction authorization. This eliminates the potential for delays in the projects due to
labor unrest, saving both time and money and preventing unnecessary risk to Airport operations.
This is the recommended alternative.
