SUBJECT:  P69 Underdock Utility Replacement (CIP #C801102) 
Amount of this request:               $3,140,000 
Total estimated project cost:          $3,450,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to advertise, award and execute a
major public works contract and fund the construction phase of the Pier 69 Underdock Utilities
Replacement Project in the amount of $3,140,000. This request would increase the total project
authorization to-date to $3,450,000. 
EXECUTIVE SUMMARY 
Underdock and associated on-dock utilities such as domestic water, fire protection water,
electrical power/shore power, communications, and sanitary sewer systems at Pier 69 are vital
to building and dock operations for both the Port and our tenants. Most of these utilities are
approaching 30 years of age, well exceeding the typical 20-year design service life. This project
would replace the aging utilities. The replacement systems are designed to provide reliable
services for the next 30 years. The design phase is expected to conclude in December and the
project is ready to transition to the construction phase beginning January, 2022.
JUSTIFICATION 
This project is an asset stewardship and revenue preservation project which would replace this
essential utility infrastructure. The project team has explored design alternatives to minimize
impacts on the environment and has selected durable materials to maximize the service life of
the systems. 
The project supports the Port's Century Agenda Goal 3, Responsibly Invest in the Economic
Growth of the Region and all its Communities and Strategy 6, Be a Highly Effective Public Agency.

Diversity in Contracting 
Diversity in Contracting has evaluated the planned construction activities and established a 10% 
WMBE aspirational goal.
DETAILS 
This project would replace aged underdock and associated on-dock utilities at Pier 69.  These
utilities  include  domestic  water,  fire  protection  water,  electrical  power/shore  power,
communications, and sanitary sewer systems. Most of these utilities are close to 30 years in age
and have exceeded their 20-year design lives. The Port's Engineering Department conducted a
comprehensive assessment of these utilities in 2019. The assessment noted that, while some
utilities have been partially replaced in various locations over the years by Marine Maintenance,
most of the utilities, associated supports/connections, and other related equipment are in poor
or very poor condition and should be replaced.
The Port's Engineering Department has completed the final design and have carefully selected 
durable materials that can withstand the harsh underdock environment over time and minimize
the total cost of ownership. It is expected the design life for the replacement system would be
at a minimum of 30 years and with some components up to 50 years. 
The December 2020 design funding commission action had anticipated construction funding
authorization the second quarter of 2021. Due to the volatile construction materials pricing and
construction labor related concerns associated with the pandemic, a decision was made to
postpone the construction funding request and the construction contract advertisement to late
2021 to allow prices to stabilize and construction contract to be bid in a more favorable bidding
time of the year.
Scope of Work 
The following are the major elements of the underdock utility replacement project. Most of the
work will be subject to tidal constraints and challenging underdock conditions.
Replace underdock electrical power feeds/conduits to the building and bullrails, and
some above dock panel/switches and transformer associated with the underdock
system 
Replace underdock potable water and fire protection mains serving the building and the
bullrails, including associated valves, meters and enclosures 
Replace underdock sanitary sewer piping 
Replace underdock communications conduits/cabling 
Replace associated underdock utility support infrastructure and anchorages 
Remove abandoned underdock utilities

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do nothing  continue to repair underdock and related utilities when problems
occur. 
Pros: 
(1)   Would preserve capital capacity for other priority projects and financial initiatives 
(2)   Would avoid temporary construction impacts to Pier 69 and tenant operations 
Cons: 
(1)   Failures would continue to occur  the disruption to operations and costs of emergency
repairs would be significant to both the Port and our tenants 
This is not the recommended alternative. 
Alternative 2  Replace the underdock and related utilities in a phased approach based on
severity of conditions. 
Pros: 
(1)   Would preserve some capital capacity for other priority projects and financial initiatives. 
(2)   Would  avoid  temporary  construction  impacts  to portions  of  Pier  69  and tenant
operations 
Cons: 
(1)   Failures would continue to occur  the disruption to operations and costs of emergency
repairs would be significant to both the Port and our tenants. 
(2)   Completing the project in phases would result in higher combined project costs. 
This is not the recommended alternative. 
Alternative 3  Replace the underdock utilities and install some replacement utilities above pier
to increase resiliency.

Meeting Date: November 16, 2021 
Pros: 
(1)   Would proactively  replace  the  end-of-life underdock  and  associated utilities  and
preserve leasehold revenue 
(2)   Would significantly decrease the risk of utility failures and the associated disruption to
operations. 
(3)   Would improve asset stewardship by capitalizing on the opportunity to increase
resiliency for some utilities by locating them out of the harsher under pier environment 
and thereby increase the service life for portions of the new systems 
Cons: 
(1)   Most utilities still need to remain under pier. For example sanitary sewer system is fed
by gravity and significant challenges would be encountered and higher costs would
result to convert to forced main systems.  Also many utilities are located under the
concrete apron (non-building portion of the pier) and though some of these could be
relocated to the bullrail but they still would be subject to weather conditions. 
(2)   Would require investment of capital funds 
This is not the recommended alternative. 
Alternative 4  Replace the underdock and related utilities based on Port of Seattle Engineering
Department's recommendations. 
Pros: 
(1)   Would proactively  replace  the  end-of-life underdock  and  associated utilities  and
preserve leasehold revenue 
(2)   Would significantly decrease the risk of utility failures and the associated disruption to
operations 
(3)   Would improve asset stewardship by capitalizing on the opportunity to use more
durable materials, thereby increasing the service life of the new systems 
Cons: 
(1) Would require investment of capital funds 
This is the recommended alternative.
