SUBJECT: Vertical Conveyance Modernization Project Change Order #109 (CIP #C800251)
Amount of this request:
NONE
Total estimated project cost:
$5,104,121
ACTION REQUESTED
Request Commission authorization for the Executive Director to execute Change Order 109 to
Contract MC-0317730, Vertical Conveyance Modernization Phase 1 at Seattle-Tacoma
International Airport, to extend the contract duration by 168 calendar days and for the
deductive amount of $10,000. No additional funds are being requested.
EXECUTIVE SUMMARY
This project provided complete modernization of eight elevators, added hydraulic cooling units
to twelve existing elevators in the Main Terminal and replaced four escalators at the north end
of the Main Terminal.
The original construction contract was $4.6 million. The execution of this change order
reconciles all contract time and cost issues with the contractor, Absher Construction, and
results in a cost credit back to the Port of $10,000. No additional funds are needed.
JUSTIFICATION
The existing elevators included in this project were installed in the 1960’s and 1970’s and the
existing escalators were installed in 1970 and upgraded in 1990. Due to their age and
technology, the controls, drives and door actuators of these elevators and escalators became
uneconomical to maintain.
Installation of hydraulic oil cooling packages improved the reliability of the existing hydraulic
elevators by eliminating or decreasing outages due to overheating, thus improving the Airport’s
experience for passengers who are unable to use the stairs or escalators.
Below is a listing of the elevators and escalators completed in this contract.

DETAILS
On April 21, 2014, the Port executed a construction contract with Absher Construction for the
amount of $4,603,000 with a contract completion date of April 20, 2016 (duration of 730
calendar days). Through the Change Order process, 76 days of time were added to the contract
for a Substantial Completion date of July 5, 2016 (41 plus 35 days on 2 Change Orders).
The Contractor experienced labor and production issues which delayed the project completion
by 168 days until 12/21/2016, when Substantial Completion was accomplished. Post Substantial
Completion, design errors were identified during a Labor & Industries permit inspection on
elevator MT-3, which was required to be corrected. This Change Order settles the final cost
and time due to delays caused by both the Port and the Contractor.
Scope of Work
Work included development of infrastructure to modernize seven existing elevators and four
escalators, and retrofit twelve hydraulic elevators with hydraulic oil cooling systems.
Infrastructure development included:
