ACTION ITEM                            Date of Meeting       May 24, 2022 

DATE:     May 13, 2022 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Eileen Francisco, Director, Aviation Project Management Group 
SUBJECT:  Indefinite Delivery Indefinite Quantity (IDIQ) Service Agreement for Civil Design
Support Services 
Amount of this request:                       $0 
Total maximum contract cost:         $5,000,000 
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 $5,000,000 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. __8c__                              Page 2 of 3 
Meeting Date: May 24, 2022 
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 
The Aviation Project Management Group will work with Diversity in Contracting to establish
WMBE goals for this contract.  The existing civil design support services IDIQ contract has a
WMBE goal of 10%. 
DETAILS 
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,  architecture,  landscape  architecture,  mechanical,  and  electrical
disciplines. The range of projects could involve improvements to roadways, surface lots,
elevated structures, garage structures, storm drainage facilities, and landscaping. 
This request is to execute one contract valued at up to $5,000,000.  The contract will have a
five-year 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. 
In April 2021 the Port executed an IDIQ contract to provide civil design support services for a
range of anticipated projects located on the landside of the Airport.  This contract has a total
contract value of $4,000,000 and is currently supporting five separate projects. Less than ten
percent of the  contract value remains unprogrammed so additional contract capacity is
required. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Separate procurement for each project. 
Cost Implications: $0 
Pros: 
(1)   Procuring  six   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 more quickly.

(3)   Cost to the consulting community will increase as they are responding to multiple
procurements. 
This is not the recommended alternative. 
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 $5,000,000 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.
