ACTION REQUESTED:
Request Commission authorization for the Chief Executive Officer to issue Change Order No. 4
for Contract MC-0317155, Exterior Gates and Airfield Improvement Projects at Seattle-Tacoma
International Airport for an amount not to exceed $470,000.00 and to revise the project scope to
add two additional fuel hydrants at Concourse A. 
SYNOPSIS:
The ongoing airline negotiations over the 2012 Exterior Gates and Airfield Improvements
Projects resulted in a request for two additional fuel hydrant pits and the relocation of three
previously planned fuel hydrant pits located at Concourse A. These changes will allow greater
flexibility for tenants being relocated to Concourse A and helps the Airport serve a growing
number of passengers and airlines. 
A change order is required to compensate the contractor for the scope change that adds the two
additional fuel hydrants.
The construction contingency and previous budget increase will be used to pay for this change
order. No additional funds are requested.

BACKGROUND: 
The Airline Realignment program will require a number of modifications associated with the
airlines that will relocate their gates, to effectively operate in their new locations. The airline
realignment is driven by airline mergers and the growth of Alaska Airlines, which necessitates
the repositioning of airlines to different concourses and gates, hold rooms, and ticketing
positions throughout the Airport. 
With numerous airlines relocating to other gate and ticket counter locations, there are
modifications that must be addressed for the airlines to effectively operate in their new locations.
The relocations will yield a more balanced facility, increasing throughput rates in a terminal of
limited size. The Exterior Gates Project provides infrastructure improvements (such as adding
fuel hydrants) to allow airline tenants to more efficiently operate at these locations. 
CHANGE ORDER DESCRIPTION: 
The following information relates to the pending change order scope and cost: 
Change Order No. 4 
Scope of work: The contractor shall install two additional fuel hydrants at Concourse A for an
amount not to exceed $470,000.00. 
The change order is being issued as a not-to-exceed change order because many of the costs will
be paid via unit prices. The unit prices match the unit prices submitted at the time of bid. 
JUSTIFICATION: 
At the time of bid, the contract documents did not include these two additional fuel hydrants. As
the planning of the Airline Realignment program stabilized, it was determined that additional
fuel hydrants would be necessary. A change order is necessary to add these two fuel hydrants to
the contract. Preliminary negotiations with the contractor regarding this change order have
placed the maximum cost of this work at $470,000. Due to the ti me constraints resulting from
weather, airline gate availability, and reasons stated above, this will be issued as a not-to-exceed
change order. Port staff will continue to negotiate the final value as the work progresses to
minimize the schedule impact.

The following information relates to the contract and competitive award:
