ACTION ITEM                            Date of Meeting      October 26, 2021 

DATE:     September 28, 2021

SUBJECT:  Authorization for Design and Permitting of the Pier 90 East Pile Cap Rehabilitation 
(CIP # C801163) 
Amount of this request:                 $140,000 
Total estimated project cost:          $1,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to complete design and permitting
for the rehabilitation of the pile caps on the East side of Pier 90 at Terminal 91 (T91). This request
will increase the total project authorization to date to $200,000 out of a total preliminary
estimated project cost of $1,000,000. 
EXECUTIVE SUMMARY 
Design and permitting to remove and replace approximately 22 currently deteriorated timber
pile caps supporting the eastern side of the C-173 building on Pier 90 of Terminal 91, identified
in conditions surveys as having fungal rot and decay. 
While most of the over water sections of Terminal 91 have been replaced with concrete piers,
the C-173 building remains timber pile supported.  A condition survey in 2016 of the support
system showed the piles and protective wraps were in generally good condition; however, some
deterioration of the timber pile caps above these piles showed potential deterioration. 
Subsequent inspections in 2018 showed rot and fungal decay at the exposed end areas of these
pile caps extending beyond the first support pile. This project will confirm the current extent of
the affected areas, replace these deteriorated sections and protect the pile caps from further
deterioration.

Meeting Date: October 26, 2021 
JUSTIFICATION 
While no displacement or significant failure of the support system has been noted to date, these
pile caps are integral to the structure of the C-173 building and further deterioration could lead
to significant limitation of the structure's capacity or add minimum use and loading restrictions 
for the building tenants. This  work supports the Port's asset preservation efforts and directly
contributes to the Century Agenda objective to advance maritime industries through capable
management of Port facilities. 
Diversity in Contracting 
The project team will work with the Diversity in Contracting team to set WMBE aspirational goals
during future construction phase.
DETAILS 
It is proposed to update an existing design prepared in 2018 as the basis for construction
documents for public bid. This would be completed by the original design consultant using a
Category I design contract to include a reassessment of the current condition, inclusion of
preventative measures in the design, update of construction cost estimate and support services
during construction as needed.
Scope of Work 
The design contract proposal includes a reassessment of the current condition, confirmation of
the design approach, inclusion of preventative measures in the design, update of construction
cost estimate and support services during construction as needed (to be executed by service
directive after construction authorization). While this work is adjacent to the upcoming work to
rehabilitate Berth 6&8 of Pier 90, the current plan is to address this need as soon as possible as
a separate effort, rather than waiting for the full design and permitting of the larger project. 
While the physical construction of this work will all be above the ordinary high-water mark and
high tide line, it is expected that the scaffolding necessary to provide access will extend below
these jurisdictional water levels and as such this work will require approval for in-water work
from the US Army Corps of Engineers. If the existing programmatic permit is not able to be used
for this work a nationwide permit (NWP-3, Maintenance) is preferred; however, the Corps will
make the final determination of permit pathway.  The project will also require a Shoreline
Exemption and Hydraulic Project Approval (HPA).  Permit documents will be prepared and
submitted by Port Staff. 
Along with replacement of deteriorated section the design will include flashing and other
preventative measures and improvements to prevent further deterioration of the repaired and
adjacent pile caps and extend the service life of these elements.

Meeting Date: October 26, 2021 
Schedule 
All in-water work will need to be performed during the permit fish window between August 1
and February 15 of each season according to the permitting assumptions above, pending tribal
consultation. This schedule aligns well with the activity level on the terminal which is typically
low during August and September.  Therefore, to limit the construction impact to terminal
operations the current plan is to start construction at the start of the fish window in August of
2022.

Preliminary costs based on linear feet of pile cap needing replacement and assumed soft cost
percentages.  Construction cost estimates will be updated during design based on updated
condition surveys included in the design proposal.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Defer rehabilitation of pile cap elements and continue to monitor their condition. 
Cost Implications: Low initial cost to monitor condition alone.  This would not include any
potential damage to structure which would be considerably more expensive to repair. 
Pros: 
(1) Lower initial capital cost. 
(2) Allows continued use without construction shutdowns. 
Cons: 
(1) Increasing risk to the structure if kept in use. 
(2) Significant risk of needing further load restriction up to and including full closure, heavily
impacting C-173 building tenants. 
(3) If the structure fails or needs to be closed it would not be able to reopen until fully
redesigned and permitted (approx. 18 months). 
(4) Construction costs continue to escalate so replacement would likely cost more in the
future, and still may require shutdowns of the facility in the meantime.

This is not the recommended alternative. 
Alternative 2  Rehabilitation of the deteriorated pile cap elements starting design in 2021 
Cost Implications: $1,000,000 
Pros: 
(1)   Addresses  structural  concerns  before  they  become  an  emergency  and  disrupt
operations. 
(2)   Work incorporates preventative elements that should help extend the useful life of all
pile caps and slow future deterioration. 
Cons: 
(1)   Higher capital cost. 
This is the recommended alternative.
