SUBJECT:  Two Additional International Aircraft Gates at International Arrivals Facility 
(IAF) to Meet Continuing Rapid Growth 
(CIP #C800583) 

SYNOPSIS 
This briefing provides definition as to why additional international capable aircraft gates are
necessary and explains that need with respect to current, existing year over year record growth,
and anticipated continuing future growth. 
On April 26, staff briefed the Commission that as international traffic at the Airport continues to
grow at a record pace and as the Airport continues to engage in conversations with new
international entrant carriers, there is a clear need to provide more international capable gates
than are currently planned as part of Phase I of the IAF project. During the early programming
of the IAF,  planners discussed the timing associated with maximizing the number of
international widebody gates, but deferred the additional two gates to a future date based on the
more moderate traffic growth known at that time. 
During the April 26 briefing, staff proposed that while the IAF is still in early schematic design
phase, it would be prudent to approve additional funding to convert the two Phase II Concourse
A gates to international widebody "swing gates" capable of handling both domestic and
international arriving aircraft and passengers. That conversion would increase the number of
international widebody gates from 18 to 20. 
Early execution of this Phase 2 work will accomplish the following objectives: 
Provide two additional needed widebody, FIS connected gates faster than alternatives 
Reduce risk of market volatility and escalation impacting price 
Take advantage of resources already mobilized for the IAF project and reduce future
Phase 2 work 
Enhance opportunity to coordinate construction sequencing with on-going operations
and minimize disruption 
Ensure uniformity in design (if built under a separate contract at a later date, there is no
guarantee that the same design team would be involved)

Staff will return on July 12 to confirm their recommended solution to address this urgent need,
confirm their $41 million estimated cost to implement solution and request authorization to
increase the total IAF cost from $608,365,000 to $649,365,000 and approval to add the early
execution of this Phase II scope to the design-build contract. 
BACKGROUND 
Air carrier service at the Airport has experienced tremendous growth. In 2011, the Airport had
14 international services. By the end of this year, that number will be 22. Furthermore, existing
services on British Airways, Condor, EVA, Emirates, and Icelandair have all increased their
frequencies  and therefore their facility needs  since 2013, with Emirates alone doubling their
schedule to two daily flights. 
In July 2013, the Commission approved preliminary funds to program a replacement of the
existing under-sized and aging Federal Inspection Service (FIS) facility in the South Satellite
(SSAT) with a new IAF that will serve the Airport well into the future and facilitate thePort's 
Century Agenda objective to make the Airport the West Coast "Gateway of Choice" for
international travel. The Commission also authorized use of an alternative project delivery
method called Progressive Design Build for the IAF program. This method is newly available
for use by public agencies in Washington state and allows the Port to select a design-build team
based mainly on their qualifications with competitive pricing on certain commercial terms (e.g.,
fee, insurance, bond) as an additional selection factor. 
The Port contracted with Clark/SOM as the Design-Builder to undertake and successfully deliver
this project. The contract with Clark/SOM is a phased contract covering three distinct periods:
the Validation Period, the Guaranteed Maximum Price (GMP) Development Period (including
some preliminary base building construction e.g., site utilities and footings and the purchase of
long lead items e.g., steel), and the GMP Execution Period (full build). 
On November 17, 2015, Clark/SOM delivered the target budget and target schedule, two critical
validation period deliverables, along with the many other reports and plans required under the
terms of the contract, completing the first phase.  On December 8, 2015, the Commission
approved $275.5 million to amend the Design-Builder's contract, via a planned Post-Validation
Amendment and to initiate the second phase - the GMP Development Period. That amendment
was executed in January 2016 launching the GMP Development Period and start of design.
