ACTION ITEM                            Date of Meeting       April 14, 2020 
DATE:     April 3, 2020 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Wayne Grotheer, Director, Aviation Project Management 
SUBJECT:  Indefinite Delivery Indefinite Quantity (IDIQ) Service Agreement for Civil Design
Support Services 
Amount of this request:                       $0 
Total estimated contract cost:         $4,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute one indefinite delivery
indefinite quantity (IDIQ) professional service agreement for civil design support services in
support of multiple capital improvement program projects at Seattle-Tacoma International
Airport. The maximum value of the contract is $4,000,000 with a contract ordering period of five
years. 
EXECUTIVE SUMMARY 
There are several capital improvement program projects proposed to occur at Seattle-Tacoma
International Airport over the next five years that would require civil design support services.
Procuring an IDIQ professional service agreement for civil design support services would support
the completion of these projects and minimize overall contract administration costs.
Competitively procured IDIQ contracts are widely used public-sector contracting tools, consistent
with the Port's General Delegation of Authority, and governed by CPO-1 policy 
There is no funding request associated with this authorization; funding to utilize this contract will
come separately from individual project authorizations. 
JUSTIFICATION 
Traditionally, the Port has utilized larger project-specific professional service agreements or inhouse
design support to provide civil design support services. Given the growth in the Port's
capital improvement program it was determined that a civil IDIQ professional service agreement 
would be appropriate to supplement these services given the number, size and scope of the
capital improvement projects.

COMMISSION AGENDA  Action Item No. 6f                                   Page 2 of 3 
Meeting Date: April 14, 2020 
The contract would be available to meet the needs of the Aviation Division and would allow the
Port to respond to future design service needs efficiently and cost effectively.
Diversity in Contracting 
This procurement will have a 7% Diversity in Contracting aspirational goal. 
Scope of Work 
The contract is intended to provide civil design support services for a range of anticipated projects
located on the landside of the Airport. Anticipated design services could include civil, structural,
geotechnical, landscape architecture, mechanical, and electrical disciplines. The range of projects
could involve improvements to roadways, surface lots, tunnels, retaining walls, garage structures,
landscaping, storm drainage facilities, and treatment plants. 
This request is to execute one contract valued at up to $4,000,000. The contract will have a fiveyear
contract ordering period during which time services may be separately authorized in a
service directive. The Port will not issue any service directives that will exceed the contract's
maximum value or after expiration of the contract ordering period. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Separate procurement for each project 
Cost Implications: $0 
Pros: 
(1) Procuring up to eight or more separate contracts would allow more procurement
opportunities and more firms may be the prime consultant.
Cons: 
(1) This alternative will increase overhead and administrative cost to the Port as we would
need to manage more procurement processes and contracts. 
(2) This alternative would add four to six months to each project schedule to complete the
procurement process. IDIQ contracts allow the Port to start the consultant working
quickly. 
(3) Cost to the consulting community will increase as they are responding to multiple
procurements. 
This is not the recommended alternative.

Meeting Date: April 14, 2020 
Alternative 2  One solicitation for a single contract 
Cost Implications: $0 
Pros: 
(1) This alternative will minimize the number of procurement processes necessary for
timely completion of projects and reduce overhead and administrative cost to the Port 
(2) Cost to the consulting community would decrease as they are responding to one
procurement. 
(3) One contract with a contract value of $4,000,000 would support better contract
utilization given the range of projects potentially supported. 
Cons: 
(1) The region's Architectural and Engineering firms have expressed to the Port of Seattle
that IDIQ contracts are difficult to support since it is difficult to predict what staff is
needed. 
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
There is no funding request directly associated with this authorization. No work is guaranteed to
the selected consultants and the Port is not obligated to pay a selected consultant until a service
directive is executed. The budget for work performed under each agreement will come from
individual service directives authorizing the consultant to perform specific work on the contract
against approved project authorizations and within the total contract amount.
