COMMISSION AGENDA                   Item No.         6a 
Date of Meeting       May 18, 2010 
DATE:      May 11, 2010 
TO:       Tay Yoshitani, Chief Executive Officer 
FROM:     Michael Ehl, Director, Airport Operations 
George England, Program Leader, Aviation Capital Improvement Program 
SUBJECT:   Construction Agreements with Washington State Department of Transportation
(WSDOT) for Road and Bridge Work Surrounding the Rental Car Facility (RCF). 
Amount of This Request: $0                                        Source of Funds: N/A
ACTION REQUESTED: 
Request authorization for the Chief Executive Officer to execute the Construction Oversight
Agreement and the SR99/500 Bridge Seismic Upgrade Agreement with the WSDOT; and allow
Port Construction Services to self perform work, advertise for bids, execute and award small
works construction contracts in support of the Off-Site Roadway Improvements (ORI) project, a
component of the RCF program. No new funding is requested. 
SYNOPSIS: 
The Port must complete the ORI project to support the operation of the RCF. WSDOT is
planning to complete bridge seismic improvements in the same construction work area.
Authorization of both construction agreements allows the Port to proceed with the ORI project,
and allows the Port and WSDOT to accomplish the work efficiently as a single project under
Port control while providing for the appropriate cost sharing between the two agencies. The
Commission previously authorized the budget for this agreement on December 15, 2009 and the
project is funded by Customer Facility Charge (CFC) revenues or bonds. 
BACKGROUND: 
The RCF program includes three main projects: the Consolidated Rental Car Facility (including
the facilities at the Airport's Main Terminal to support the consolidated busing operation), the
Bus Maintenance Facility, and the Off-Site Roadway Improvements. The ORI project surrounds
the Consolidated Rental Car Facility site and includes improvements to WSDOT, City of
SeaTac, and Port owned transportation facilities. The ORI project also meets the commitments
identified in the SEPA and NEPA environmental review documents for the RCF program.

WSDOT has budgeted funds to complete a seismic upgrade to the International Blvd. bridge that
crosses over State Route 518 and will be widened by the ORI project. Port and WSDOT staff
have agreed to include the seismic upgrade project into the ORI project so that there is one
construction effort in order to provide a cohesive single bid package, reduce the overall impact to
the community, and reduce the costs of administering both construction efforts for both agencies.
The costs of the seismic upgrade project will be fully borne by WSDOT. 
In order to complete the construction of the ORI project, the Port needs to enter into two separate
agreements with WSDOT: a construction oversight agreement and a SR99/500 Bridge Seismic
agreement. Since the work completed within WSDOT's right-of-way will be owned by WSDOT
at the completion of the ORI project, the construction oversight agreement provides the
mechanisms to make sure these improvements meet WSDOT's requirements. The SR99/500
Bridge Seismic agreement addresses how the Port will complete the seismic improvements for
WSDOT as part of the ORI project, and how the Port will be reimbursed by WSDOT for this
work. The attached map (Attachment A) depicts the scope of the improvements for the ORI
project and the areas that are included with each agreement. 
On December 15, 2009, the Commission authorized the construction funds and granted approval
to advertise for construction the ORI project. This previous authorization did not grant Port
Construction Services the authority to self perform work, advertise for bids, or execute and
award small works construction contracts. It is now anticipated that Port Construction Services
may be needed to support the ORI project, specifically the removal and disposal of contaminated
soils and utility work. This authority is now being requested. 
CONSTRUCTION OVERSIGHT AGREEMENT: 
The Construction Oversight Agreement (see Attachment B) meets the requirements of the ORI 
project and has been reviewed by Port staff and the legal department. The agreement includes
the following key factors: 
The Port has coordinated with WSDOT to develop the plans, specifications, and cost
estimates for the project in accordance with WSDOT standards for the portion of work that is
within WSDOT right-of-way or where WSDOT has jurisdiction. 
The Port will administer the construction contract and will obtain WSDOT's written approval
prior to any changes to the plans or specifications. 
The Port will reimburse WSDOT for the actual costs of construction oversight for the portion
of work that is within WSDOT right-of-way or where WSDOT has jurisdiction. The costs for
construction oversight are estimated at $405,000 and these funds are included within the
current authorized budget.

WSDOT grants the Port right of entry upon WSDOT land for the purpose of constructing the
project, and the Port grants WSDOT right of entry upon Port land for the purpose of
constructing the project. 
The Port will be responsible for all communications with the public during the construction
of the project. 
WSDOT will own, operate and maintain the portion of the project construction within
WSDOT right-of-way. 
Specific requirements for the review of construction submittals, project inspections, and
acceptance of work by WSDOT. 
SR 99/500 BRIDGE SEISMIC UPGRADE AGREEMENT: 
The SR 99/500 Bridge Seismic Agreement (see Attachment C) meets the requirements of the
ORI project and has been reviewed by Port staff and the legal department. The agreement
includes the following key factors: 
WSDOT developed plans, specifications, and cost estimates for the bridge seismic
improvements. 
The Port has incorporated the plans and specifications into the ORI project, will administer
the overall construction contract, and will also obtain WSDOT's written approval prior to
any changes to the plans or specifications 
WSDOT will reimburse the Port for the actual costs of construction and construction
administration for the bridge seismic improvements. These costs are estimated at $761,800 
(including construction contingency) and are included within the additional contract
authorization provided by the Commission. 
WSDOT and the Port agree to jointly review and comment on any settlement of claims
associated with the bridge seismic improvements, and to jointly determine the level of
financial participation for both agencies in the negotiated claim settlement.
The Port will be responsible for all communications with the public during the construction
of the project and will follow WSDOT's "no surprises" philosophy by notifying WSDOT
immediately of any issues associated with the bridge seismic improvements. 
WSDOT will own, operate and maintain the bridge seismic improvements. 
Specific requirements for the review of construction submittals, project inspections, and
acceptance of work by WSDOT.
