ACTION ITEM                            Date of Meeting     December 8, 2020 
DATE:     November 30, 2020

FROM:    Nick Milos, Manager, Corporate Facilities 
Fred Chou, Capital Program Leader 
SUBJECT:  P69 Underdock Utility Replacement (CIP #C801102) 
Amount of this request:                  $85,000 
Total estimated project cost:           $2,930,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to authorize $85,000 in design and
permitting phase funding for the proposed underdock utility replacement at Pier 69. This funding
request would increase the total project authorization to-date to $310,000, out of a preliminarily
estimated total project cost of $2,930,000. 
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 service life. This project would
replace the aging utilities. The replacement systems would be designed to provide reliable
services for the next 30 years. 
JUSTIFICATION 
This project is an asset stewardship and revenue preservation project which would replace this
essential utility infrastructure. The project team is prepared to explore design alternatives to
minimize impacts on the environment and would select 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
(New Goal).

Diversity in Contracting 
The Port will be self-performing the design. WMBE aspirational goals for construction will be
established during the design phase.
DETAILS 
The 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 preliminary design. D uring the final design
phase additional focus will be made to carefully select 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.
Most of the utility replacement work will not be subject to in-water permitting; however, the
project is within shoreline jurisdiction and will require a shoreline exemption from the city of
Seattle. A segment of the sanitary sewer system will require additional in-water environmental
permitting approvals. It is expected that the permit approval duration may take longer; however,
staff will explore construction phasing opportunities during final design to address possible
longer permit approval duration. 
Scope of Work 
The following are the major elements of the underdock utility replacement project and 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 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.
