DATE:     January 4, 2021

FROM:    Tina Soike, Director Engineering Services 
Janice Zahn, Assistant Engineering Director, Construction Services 
SUBJECT:  Rental Car Facility (RCF) Pavement Remediation (CIP #C800977) Change Order Over
60 Days 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute a change order to
Contract MC-0319802 Rental Car Facility (RCF) Pavement Remediation for the cost of deferment
of work at Seattle-Tacoma International Airport RCF for an amount of $143,109.02 and a time
extension of 327 calendar days. 
EXECUTIVE SUMMARY 
This change order requires the addition of 327 calendar days to the contract due to the
deferment of non-essential construction in compliance with Governor Inslee's "Stay Home, Stay
Healthy" proclamation. Commission action is required under the General Delegation of Authority
because the change order includes a time extension of more than sixty days. The change order
also includes a negotiated resolution of increased costs for which the Port is responsible resulting
from the deferral of the work to 2021. No additional project funding is included with this request. 
Description of Change Order 
This change order revises the contract completion date and settles all costs due to the change in 
scheduling of the non-essential portions of the project that were a result of the Governor of the
State of Washington's "Stay Home, Stay Healthy" order to combat the spread of the COVID-19
virus. 
Background 
The RCF Pavement Remediation project includes several major maintenance improvements and
one security improvement for the facility that the Port has the responsibility to complete under
the terms of the RCF Lease Agreement. The major elements of work include replacement of the
fifth floor expansion joints, replacement of portions of the fifth floor topping slab, pavement
remediation for the S 160th St bus access, structural crack sealing for both helices, replacement
of weather proofing membranes at the car wash areas located on the second and fourth floors,
replacement of weather proofing membranes in employee and visitor parking, and replacement
of the existing perimeter fence with a no-climb fence. The major works construction contract

was executed with Swinerton Builders on August 6, 2019 and work began in October. The RCF
Pavement Remediation project is funded by Customer Facility Charge (CFC) revenues. 
On March 23, 2020, Governor Inslee issued the "Stay Home, Stay Healthy" proclamation that 
required all people in Washington State to stay at home except to conduct or participate in
essential activities, and/or for employment in essential business services. In April 2020 the Port
of Seattle Commission was briefed on the impact of the COVID-19 pandemic on Aviation revenues
and the 2020-2024 Capital Improvement Plan. The RCF Pavement Remediation project was
identified as being partially deferred where safety related work was considered to be essential
work that would be completed, but the remaining major maintenance work would be deferred.
The Port of Seattle Commission adopted Motion 2020-9 on April 28, 2020, that authorized shortterm
changes to the 2020-2024 Capital Improvement Plan in response to the COVID-19 pandemic
that included the deferment of the non-essential portions of RCF Pavement Remediation project. 
Motion 2020-9 stated that additional changes to the CIP were to be presented as part of the 2021
budget process.  The cost to complete the RCF Pavement Remediation project have been
approved by Commission as part of the 2021 budget. 
In April 2020 the Port notified Swinerton Builders that all work associated with pavement
remediation for the S 160th St bus access, structural crack sealing for both helices, replacement
of weather proofing membranes at the car wash areas located on the second and fourth floors,
and replacement of weather proofing membranes in employee and visitor parking would be
suspended. During change order negotiations Swinerton Builders informed the Port that the
water proofing membrane materials for the car wash areas had already been purchased prior to
our direction to defer work. The shelf life of the materials required that they be installed in 2020
or new materials would need to be repurchased for 2021. The cost of repurchasing the water
proofing materials was approximately $85,000. 
In May 2020 Governor Inslee issued an update to the "Stay Home, Stay Healthy" proclamation, 
which was called the Phase 2 New Construction restart. This allowed non-essential construction
projects to restart work following specific guidelines. Phase 2 construction restart took effect in
King County on June 5, 2020. On July 1, 2020, in order to avoid the large additional waterproofing
material repurchase and disposal costs, the Port directed that the replacement of the water
proofing membranes in the car wash areas located on the second and fourth floors be completed 
in July and August 2020. The reduced customer demand at the RCF facility also was a factor in
deciding to perform the work in 2020 when the impacts to RCF operations will be much less than
in 2021. 
All work associated with the replacement of the fifth floor expansion joints, replacement of 
portions of the fifth floor topping slab, replacement of weather proofing membranes at the car
wash areas located on the second and fourth floors, and replacement of the existing perimeter
fence with a no-climb fence has now been completed. With the execution of this Change Order, 
all remaining work on the project will be complete in the late spring/early summer 2021 as soon

as the weather allows the proper conditions to complete the work. The amount requested herein
includes a negotiated resolution of additional costs for which the Port is responsible resulting
from the deferral of the work to 2021. 
FINANCIAL IMPLICATIONS 
There is no additional funding being requested with this action. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Negotiate a reduction of scope for the major construction contract to eliminate
and not complete the remaining work. 
Pros: 
(1)   The Port would not pay out any more funds in 2021 on the major works construction
contract. 
Cons: 
(1)   The major maintenance work needed on the RCF would not be completed. This may
result in more deterioration of the facility, shortening the life of some parts of the
facility and the Port incurring even larger costs in the future to perform the repairs at a
later time. 
This is not the recommended alternative. 
Alternative 2  Negotiate a reduction of scope for the major construction contract to eliminate
the remaining work and add the uncompleted work to a future project planned for 2021 to
increase security at the RCF. 
Pro: 
(1)   The major maintenance work will still get done. 
Con: 
(1)   Repackaging the work into another contract will increase the Port's soft costs and add
complexities in managing the work as we would have more than one designer of record
on a project. 
(2)   Repackage will take time and may delay the bidding of the work planned for 2021 that
the Rental Car Agencies desire to be performed as early as possible. 
This is not the recommended alternative. 
Alternative 3  Approve the additional costs and contract time extension to complete the
remaining work in 2021

Meeting Date: February 9, 2021 
Pros: 
(1)   Completes the work as early in 2021 as weather condition allow. 
(2)   The RCF is properly maintained for years of future use and revenue generation. 
Cons: 
(1)   Additional costs will be expended and paid from the existing approved project budget. 
This is the recommended alternative.
