ACTION REQUESTED 
Request Commission approval of a technical correction to the action request of agenda
item 6c of December 8, 2015, that does not alter the authorization amounts or the projects
for which authorization was granted,  to read as follows: Request Commission
authorization for the Chief Executive Officer to take the following actions to advance two
significant capital projects at Seattle-Tacoma International Airport, as described in
Attachments A and B, by (1) increasing project authorizations, and executing contract
amendments and change orders for the International Arrivals Facility Program in the
amount of $275.5 million and for the North Satellite Renovation & North Satellite Transit
Station Lobbies Project in the amount of $98.1 million for a total of $373.6 million
additional authorization for the two projects; (2) executing a contract for project specific
construction audit services for the term of each project; and (3) amending the previous
Commission authorization for the IAF validation contract not-to-exceed amount to
include sales tax for the estimated amount of $570,000. 
BACKGROUND 
On December 8, 2015, the Commission approved a combined action request to advance
two significant capital projects at Seattle-Tacoma International Airport; the International
Arrivals Facility and the North Satellite Renovation & North Satellite Transit Station
Lobbies Project. Following Commission approval of this request, it was noted that the
request restricted the authorization to specific contractors  and limited funding the
program as intended and as described in the presentation. The proposed corrected
authorization does not alter the authorization amounts, nor the projects or purposes for
which the authorizations were sought and as described to the Commission during
presentation on December 8. 


Template revised May 30, 2013.
