ACTION ITEM                            Date of Meeting    September 13, 2022 
DATE:     August 22, 2022 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Janice Zahn, Interim Director of Engineering 
SUBJECT:  Parking Garage Elevator Modernization  (CIP #C800789) Change Order Over
$300,000 and Time Extension Over 60 Days 

Amount of this Request:            $0 
Total estimated project cost:        $23, 276,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute a Change Order to
Contract MC-0320162 Parking Garage Elevator Modernization for modifications and delays
associated with revisions to the interior cab elevator finishes at Seattle-Tacoma International
Airport for an estimated amount not to exceed $3,500,000.00 and time extension over 60 
calendar days. 
EXECUTIVE SUMMARY 
This change order request requires no additional budget (zero dollars) because it can be
accommodated within previously authorized budget. It requires additional time due to delays 
associated with the fabrication and acceptance of the interior cab mock-up due to a Port design
error and omission. Commission action is required under the General Delegation of Authority
because the value of the change order is over $300,000 and the additional time is over 60
calendar days. 
Description of Change 
This change order restores the textured stainless-steel finishes inadvertently deleted during the
bidding process; compensates the contractor’s extended overhead costs associated with delays
of the approval and acceptance of the interior cab mock-up; and extends the contract time for
up to 270 calendar days associated with these revisions 
Background 
The Seattle-Tacoma International Airport parking garage elevators provide vertical circulation
services for millions of airport parking and ground transportation customers every month.
Continued and reliable operations of the elevators are vitally important to the traveling public as

well as Airport operations. There are 27 elevators in the parking garage which vary by age and
condition. This project fully replaces 10 elevators and modernizes the other 17. In addition to 
improving reliability and refreshing the cab interiors, the completed project will also reduce
energy usage in the Airport parking garage by an estimated 56,000 to 211,000 kilowatt hours
(kWh) per year. 
The parking garage elevators are the first and last areas of the airport that passengers see as they
travel through the airport.  As such, considerable time was spent during design to create a
finished interior that provides a sense of the Pacific Northwest while also providing a durable and
resilient finish.   These  resilient  finishes were  based  upon products  from  three  different
manufacturers, Forms+Surfaces, Rigidized & McNichlos. These three specific manufacturers
were included in the initial bid documents. During the Advertisement and Bidding period for this
project, the stainless-steel finishes were unintentionally deleted from the Custom Elevator Cab
Finishes specifications.  This deletion resulted in the carefully selected stainless steel finishes 
being removed from the contract and replaced with a much less durable and bland stainless steel
brushed #4 finish.

the Port 

After the contract was executed, the Contractor began the shop drawing/submittal process for
the custom elevator cab finishes. As part of this process, Requests for Information (RFIs) were
submitted by the Contractor for clarification of the design documents. While preparing the
response to the RFIs, it the Port realized the original stainless steel finishes had been deleted
from the contract and needed to be restored.
The Port developed a revised design of the interior finishes to restore the original design intent
and minimize the added costs. The Contractor is currently building the mockup for Port’s review
and acceptance. It’s anticipated the mockup will be completed in October 2022. Completion of
the mockup has been impacted by supply chain issues and the conflict in Ukraine (30% of the
world’s nickel used to make stainless steel comes from Russia). Currently the contract has been
suspended until the mock-up is accepted. A new contract completion date will not be known until
the full-scale mockup has been accepted by the Port of Seattle. 
FINANCIAL IMPLICATIONS 
There is no additional funding being requested in this memo.
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Construct elevator cabs with specified Brushed #4 stainless finish. 
Pros: 
(1)   Additional Project cost is minimized. 
(2)   Delays to project would be minimized 
Cons: 
(1)   Additional lifecycle costs due to less durable finish. 
(2)   Reduced customer experience due to lower level finishes 
This is not the recommended alternative. 
Alternative 2 – Terminate the contract for convenience and re-bid.
Pro: 
(1) Project would be competitively bid with the original design intent

(2) Would Port to construct mockup prior to resolicitation. 
Cons: 
(1) Potential cost savings from bid vs negotiation would likely not be realized due to
additional project costs associated with: 
o  Cost of procurement process 
o  Additional costs due to further price escalation of material 
o  Higher labor costs due to annual wage increases 
o  Additional Port costs for storage and handling of already procured material. 
(2) Project would likely be delayed an additional 9-12 months. 
This is not the recommended alternative. 
Alternative 3 Perform work as Change Order to Parking Garage Elevators Modernization 
Pros: 
(1) Eliminates delay of 6-9-months for a new procurement. 
(2) Minimizes delays and risk of elevator failures. 
(3) Eliminates soft costs for procurement and settlement of termination costs to the Port. 
(4) Reduces risk of material and labor escalation by completing work sooner. 
Cons: 
(1) Direct cost of the work could be greater than competitive bid. 
This is the recommended alternative.
