ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute up to two professional
services indefinite delivery, indefinite quantity (IDIQ) contracts for Dredging Support Services
totaling no more than $2,000,000 with a five-year contract ordering period. No funding is
associated with this request. 
SYNOPSIS 
Dredging is required to maintain and improve essential navigational access at existing Port of
Seattle and NWSA operated Maritime Terminals and Marinas. Exact scope and timing of these
projects are subject to future surveys and business needs. The proposed professional services
IDIQ contracts would allow the Port to be able to respond to future service needs
efficiently. Previously procured dredging IDIQ contracts are now beyond their ordering
periods. 
Diversity in Contracting 
The project team is working with the Diversity in Contracting department to identify WMBE
aspirational goals and inclusion plans in association with these IDIQcontracts. 
DETAILS 
The IDIQ contracts will be procured according to Port policies and procedures in accordance
with Delegation of Authority and Procurement policies. The contracts will be written with
specific not-to-exceed amounts and identify the services required. Each contract will have a
contract ordering period (during which the services may be separately authorized) of five years.
The actual contract duration may extend beyond five years to complete work identified in

service directives. Service directives may only be issued during the contract ordering period and
within the total original contract value.
Individual service directives consisting of a scope, level of effort, and schedule will be
negotiated and executed as needed. Funds will be derived from separate project authorization
requests so there is no funding request associated with this memo. 
Scope of Work 
General scope of work will cover planning, design, permitting and construction support
pertaining to dredging and navigational access at Port of Seattle and NWSA Maritime facilities. 
Schedule 
The IDIQ service agreement will have a contract ordering period of five years during which
service directives may be issued. Each service directive will specify the scope, duration, and
schedule associated with the work. This contract ordering period will ensure continuity of
efforts. The contract may extend past the five-year ordering period, but no new service
directives will be issued after the ordering period or when contract funding capacity is reached,
whichever occurs first. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Procure project-specific contracts to support capital and operational activities 
Pros: 
(1)   Expands opportunities for firms to participate. 
Cons: 
(1) Doesn't allow for preliminary work to support capital projects or operational activities 
(2)   Does not allow for time-sensitive tasks, leading to delays and increased costs. 
(3)   Inhibits continuity and development of institutional knowledge. 
(4)   Staffing   costs   significantly   increase   to   support   contract   procurement   and
administration. 
This is not the recommended alternative.
