TO: Stephen P. Metruck, Executive Director
FROM: Tina Soike, Director Engineering Services

SUBJECT: Air Cargo Road Safety Improvements (MC-0320017/WP#U00085) Change Order
Over 60 Days
ACTION REQUESTED
Request Commission authorization for the Executive Director to execute a change order to
Contract MC-0320017 Air Cargo Road Safety Improvements to add up to 100 Calendar days to
the Contract duration to reconcile the contractual completion date to the actual completion date.
EXECUTIVE SUMMARY
This change order requires the addition of up to 100 calendar days to the Contract duration.
Commission action is required under the General Delegation of Authority because the Change
Order includes a time extension of more than sixty days. No additional project funding is required
with this request.
Description of Change Order
This change order revises the contract completion date.
Background
The Air Cargo Road Safety Improvements project is a renewal and replacement project that brings
the roadway corridor up to current standards for operation and safety and completes the
permanent access improvements for the Cell Phone Lot. Air Cargo Road was originally
constructed circa 1970 and is the primary access for a number of airfield, cargo, and landside
facilities. The existing pavement and lighting systems between S. 166
th
St. and S. 170
th
St. are
failing and are well beyond their useful life. The Cell Phone Lot was relocated in 2014 to its current
location to support the expansion of aircraft hardstand parking on the airfield. The roadway
improvements include pavement rehabilitation, traffic signals, roadway illumination, signage,
sidewalks, parking lot modifications, bus stops, utilities, landscaping, and intelligent
transportation systems.
On March 20, 2021, the Port executed a construction contract with Tucci and Sons, Inc. in the
amount of $5,002,963.30. The Contract was set up to be completed in two phases. Most of the
work was scheduled to be completed by October 8, 2021, as part of the first phase. The second

phase included the traffic signals, roadway illumination, and intelligent transportation systems
and was scheduled to be completed by January 16, 2022, since we anticipated that some
materials would take longer to procure and install. We did complete the first phase on time and
reopened the Cell Phone Lot with the new entrance to the public on October 8, 2021.
Unfortunately, the long lead items have taken even more time to procure than anticipated which
is driven by COVID supply chain issues. The decorative roadway illumination fixtures have been
the hardest item to receive. The light fixtures were modified at the request of the City of SeaTac
to match their standard and the costs were settled in Change Order #5 on August 6, 2021. Costs
for this change was captured in a change order but the long procurement of these light fixtures
was not foreseen at the time of the change. The Port and the Contractor mutually agreed that
this procurement delay is out of the control of both the contractor and Port, and we are granting
a time extension for up to 100 Excusable and Non-Compensable Days. The current value of the
Contract is $5,901,781.27.
FINANCIAL IMPLICATIONS
There is no additional funding being requested with this action.
ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 – Do not authorize the issuance of the Change Order and delete the light fixtures
from the contract.
Pros:
(1) The contract might be closed out earlier than the current schedule.
Cons:
(1) The project would not complete the roadway illumination improvements bringing the
roadway corridor up to current standards. This might put the Port at legal risk if
someone was injured on our property or within the adjacent City right-of-way.
(2) The Port’s obligations under SEPA and to the City of SeaTac for the Cell Phone Lot are
not satisfied.
This is not the recommended alternative.
Alternative 2 – Authorize the issuance of the Change Order to extend the Contract duration by
up to 100 days.
Pros:
(1) This completes the roadway illumination improvements bringing the roadway corridor
up to current standards.
(2) The Port’s obligations under SEPA and to the City of SeaTac for the Cell Phone Lot are
satisfied.
(3) The Port staff has analyzed the schedule delays and established the change order
amount and time extension that is fair and reasonable.
