ACTION ITEM
Date of Meeting
November 14, 2017
DATE: October 20, 2017
TO: Dave Soike, Interim Executive Director
FROM: Ralph Graves, Senior Director, Capital Development
Janice Zahn, Assistant Engineering Director, Construction Services
SUBJECT: Central Terminal Stairs Project Change Order # 10 (CIP #C800716)
Amount of this request:
$0
ACTION REQUESTED
Request Commission authorization for the Executive Director to execute Change Order 10 to
Contract MC-0318654, Central Terminal Stairs Project at Seattle-Tacoma International Airport,
to extend the contract duration by 76 calendar days and for the deductive amount of
$64,508.00. No additional funds are being requested.
EXECUTIVE SUMMARY
This project built two stairways near the central checkpoint to provide egress capacity from the
mezzanine level of the Airport to remedy fire life-safety concerns and allow use of unoccupied
portions of the building. Gaining additional usable assembly and office space within the limited
footprint of the terminal is valuable to both airlines and traveler services. The stairways and fire
sprinklers increase safety and accessibility for airport users.
The original construction contract was $1.55 million, with a total project budget of $2.9 million.
The execution of this change order reconciles all contract time issues with the contractor, PCL
Construction. All 76 days are inexcusable and result in a cost credit back to the Port of
$64,508.00. No additional funds are needed.
JUSTIFICATION
Airport staff is managing an increasingly scarce resource of available office space in the main
terminal largely due to continued growth in demand from airlines operating at the Airport. This
project is now in use and has made 10,000 square feet of previously un-leasable space usable
with proper code compliant egress.
It should be noted that in addition to providing sprinklers that benefit the two stairs and their
associated egress pathways, the fire sprinklers benefits the Baggage Optimization project which
will be able to use an egress pathway nearby once the fire sprinklers are installed.

DETAILS
On September 29, 2016, the Port executed a construction contract with PCL Construction for
the amount of $1,546,759.00 with a contract completion date of May 30, 2017. Early in the
project the completion date was revised to April 28, 2017 as a result of a value engineering
change. The actual Substantial Completion was not achieved for the project until July 13, 2017,
a project delay of 76 calendar days.
The contractor experienced production issues with the installation of the stainless steel
paneling. This was the single issue that caused the time impact and ultimately caused the delay
to the contract. The contractor eventually completed the panel installation allowing the Port to
issue Substantial Completion. Since this panel work is base contract work, the contractor is
solely responsible for the 76 days of schedule delay.
Scope of Work
Work elements included installation of two new stairways from the mezzanine to the concourse
level and installation of a fire sprinkler system.
