PORT OF SEATTLE

MEMORANDUM

DATE: April 25, 2011

SUBJECT: Project specific Design Services at Seattle-Tacoma International Airport for the

South Satellite HVAC, Lights, Ceiling Replacement Project CIP # C800376 and

North Satellite HVAC, Lights, Ceiling Replacement Project CIP # C800377

Amount of This Request: $0 Source of Funds: Future Individual Project

Authorizations

ACTION REQUESTED:

Request Port Commission authorization for the Chief Executive Officer to execute a professional

SYNOPSIS:

This contract will provide design services for projects supporting the replacement of the HVAC,

Lighting and Ceilings in the North and South Satellites at the Airport. Each project will return

with a request for design funds as part of a later project authorization. At this time, the South

Satellite project is definite, and the North Satellite is prospective due to ongoing airline

discussions about realignment-related projects. However, staff sees potential advantages in

having the same design consultant for both projects. If the North Satellite project is delayed or

otherwise accomplished, then that work can be omitted from the design contract since no funds

are obligated to the design until after the Commission authorizes the project and contract service

BACKGROUND:

The Port of Seattle is planning to replace the HVAC Systems on the North and South Satellites at

the Airport. The current systems have exceeded their 25 year service life, and replacement parts

are unavailable when repairs are required. The current systems are obsolete and the potential

cost savings from replacement by new energy efficient systems is substantial. The current

construction cost estimate for the two projects is $55 million.

years. Service directives will be issued during the ordering period and the contract duration will

continue until the work is complete. The planned construction includes demolition and

replacement of HVAC, lights, ceilings and related infrastructure.

 Sign contract – Oct 2011

 Design Complete – July 2012

 Advertise for construction – Sep 2012

 Notice to proceed to construction contractor – Jan 2013

specific scope of work to be accomplished for each project will be identified in a series of

service directives. The service directives also will include the schedule and cost of services to be

provided by the consultant for each project.

FINANCIAL IMPLICATIONS:

The total estimated cost for services will not exceed $8,000,000. No work is guaranteed to the

chosen consultant, and the Port is not obligated to expend any funds by execution of a contract.

The budget for work performed under this contract will come from separate individual

authorizations for capital project work. Consequently, there is no funding request associated

ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS:

same consultant design both facility upgrades, the systems can be standardized, resulting in

future savings of spare parts inventories and training of maintenance personnel. Using the same

consultant will result in design economies. Advertizing the contract to include both designs does

not commit the Port, but it enables the option for the second if the first design goes well. This is

the recommended alternative.

Alternative 2: Prepare separate procurements for each project. This alternative would require

more procurement processes, add more time to projects, preclude the possibility of using one

designer for both projects and increase administrative costs. This is not the recommended

alternative.

The Commission was briefed on the condition of the HVAC systems of the North and South

Satellites on September 22, 2009, in a briefing entitled “Sea-Tac Airport: Renewing Mission

Critical Infrastructure.”
