SUBJECT:   T91 Domestic Waterline Renewal (C801243) 
Amount of this request:               $4,500,000 
Total requested project cost:          $4,750,000 

ACTION REQUESTED 
Request Commission Authorization for the Executive director to approve construction costs of
$4,500,000 for a total project cost of $4,750,000 for the Terminal 91 Domestic Waterline Renewal
and to use Port of Seattle crews to perform the work over an eight-year period. 
EXECUTIVE SUMMARY
The work will consist of replacing domestic waterlines which serve the vessels at Piers 90 and 91.
The domestic waterlines support the North Pacific Fishing Fleet, cruise vessels, and other
commercial vessels that call at Terminal 91. This project will restore waterlines that are at end
of their service life, some of which are on the verge of failure. Moving forward with this project
will restore infrastructure vital to Maritime Operations for the next fifty years. 
JUSTIFICATION
The existing piping is galvanized steel and, in some cases, older than 50 years. Several areas have
become thin and are currently leaking while others remain in usable condition. Extending the
construction timeline over multiple years allows for coordination with planned capital projects 
and allows the replacement of piping according to the level of degradation. This approach also 
avoids replacing some sections where other project work will interfere with this effort or
otherwise cause rework. There are multiple projects taking place over the next 2-7 years, some
of which may require sections of piping to be removed during construction. With the use of Port
Crafts’, we anticipate being able to accommodate these projects and to plan around them,
thereby taking advantage of in-house flexibility.

Diversity in Contracting 
The office of Diversity in Contracting has been involved in Acquisition Planning and strategy
discussions. The total of this work has been planned to take place over several years with
milestone goals to contract some portions using small and, or WMBE firms to perform the work.
There is a goal of spending 10% of the construction costs using WMBE and Small business
resources. 
DETAILS 
This project was originally budgeted for $850,000 for 2021 to replace waterline which at the time
was failing or in poor condition, totaling 3,000 LF of pipe replacement only. Seed funding was
authorized by Kenneth R. Lyles followed by Commission Authorization of $250,000 total, for
design. Through the design process it was realized that significant improvements in seismic
bracing and other code requirements were needed when replacing the domestic waterline. The
design assessments of all the piping and needed improvements suggested that 100% of the
domestic waterline should be upgraded. The current estimate for construction is $4,500,000 
which does not include the portion to be replaced by U00554/U00704 Berths 6 & 8
Modernization project. 
The scope of work has been evaluated in terms of piping sections requiring immediate
replacement, areas requiring replacement in 1-3 years, areas requiring replacement in 3-6 years
and those areas which have been replaced due to failure but require seismic upgrades and valve
replacements. Approximately 80% of the existing piping has yet to be replaced and 100% requires
seismic upgrades and other improvements. 
Port of Seattle Engineering has completed a comprehensive design for replacing all the existing
galvanized domestic waterline and bringing the system up to current seismic and sanitary code.
The design is currently under floodplain code review at SDCI and all permitting, other than
Mechanical, is expected to be complete by February of 2024. 
Portions of this work may be contracted to serve the most efficient delivery while coordinating
with other project work, Operations, and avoiding rework. 
Scope of Work
Port Crafts will replace existing galvanized steel piping with new stainless-steel piping, fittings,
valves and supports. Seismic bracing will be installed to comply with current seismic code
requirements. 
Schedule: 
(1)   2024, Replacement of 400’ of piping, Seismic Upgrades to 800’ of piping. 
(2)   2025, Replacement of 1,000' of piping, Seismic Upgrades to 1,000' of piping 
(3)   2026, Replacement of 1,000' of piping, Seismic Upgrades to 1,500' of piping 
(4)   2027, Replacement of 1,000' of piping, Seismic Upgrades to 1,500' of piping

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
The following alternatives have been considered for the execution of this work: 
Alternative 1 – Contract Work through a Competitive Bid Process, Perform work over a two-year
period.
Cost Implications: Construction Costs $5,750,000 
Pros:
(1)   Domestic Waterline Replacement over a shorter duration 
(2)   Avoidance of materials and labor escalation 
(3)   Project would proceed as permitted with no modifications required.
Cons:
(1)   Likely interruptions and change orders to conflict with other project work and ongoing
operations at the Terminal. 
(2)   Likelihood of re-work due to interference with other project work requiring removal of
piping. 
(3)   Potential of extending to a third year to avoid conflicts with Cruise Season, ongoing
project work and operational needs. 
This is not the recommended alternative.

Meeting Date: February 13, 2024, Commission Meeting 
Alternative 2 – Contract work over a 6–8-year period.
Cost Implications: Construction Costs $6,300,000 
Pros:
(1)   Avoidance of rework and interference with other project work.
(2)   Opportunity to use On-Call project specific contracts with WMBE firms. 
(3)   Allows flexibility to adapt contracting methods over consecutive years. 
Cons:
(1)   Does not eliminate all of challenges in coordinating Operational needs with Contracted
work. 
(2)   Additional costs due to multiple contracts, added overhead, and escalation to labor and
materials over multiple years. 
(3)   Increased costs due to subcontractor mark-up and likelihood of market fluctuations. 
(4)   Potential for material lead time challenges. 
(5)   An alternative permitting approach would have to be pursued.
This is not the recommended alternative. 
Alternative 3 – Use Port Crews with Opportunities to Contract Portions using On-Call Contracts,
JOC or Bid work. 
Cost Implications:  Construction Costs $4,500,000 
Pros:
(1)   This method allows for more control over coordinating ongoing project work with
replacement of piping over time. This also allows for ease of coordination with
Operational needs. 
(2)   This approach limits added contracting costs and uses a cost-benefit approach to piping
replacement. 
(3)   Least likely chance of rework or interference with other project work. 
(4)   opportunities to avoid lay-offs during seasonally slow periods. 
(5)   Opportunities to contract with WMBE firms for low risk portions of the work. 
Cons:
(1)   Extended timeline for full replacement of domestic waterline. 
(2)   Material escalation due to extended timeline. 
(3)   An alternative permitting approach would have to be pursued.
This is the recommended alternative.

CPE Impact                       N/A 
Future Revenues and Expenses (Total cost of ownership) 
Extending the useful service life of our existing assets defers eventual replacement costs for a
longer period, supporting the economic vitality of our operations. Other economic benefits
include cost effectiveness and minimum disruption to the terminal operations.
