COMMISSION AGENDA               Item No.      4g 
ACTION ITEM 
Date of Meeting     August 5, 2014 
DATE:    July 29 2014 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:   Michael Ehl, Director, Airport Operations 
Wayne Grotheer, Director, Aviation Project Management Group 
SUBJECT:  2014 Airfield Improvement Project (CIP #C102573) 
ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to execute a major public
works construction contract with the sole responsive and responsible bidder to perform the 2014
Airfield Improvement Project at Seattle-Tacoma International Airport. 
SYNOPSIS 
On July 1, 2014, the Commission authorized rejection of all bids for the earlier advertised 2014
Airfield Improvement Project that contained more scope and was combined with the North
Satellite Ceiling Leaks project. The Commission also authorized the advertisement of the 2014
Airfield Improvement Project with a subset of the previous contract. Outreach occurred to the
contractor community prior to advertisement and the contract contained provisions intended to
attract more bidders. Bids were opened on July 22, 2014 and found to be irregular as there was
only a single bidder and the bid was more than ten percent (10%) over the engineer's estimate.
The single bid is in the amount of $969,100, which is thirty-four percent (34%) over the
engineer's estimate of $723,860. Staff recommends accepting the bid and authorizing execution
of the major works contract with the sole bidder as the work is considered essential to airport
operations and the work needs to occur prior to the approaching seasonal, inclement weather. 
BACKGROUND 
The current 2014 Airfield Improvement Program is part of an ongoing program to replace
distressed pavement on the airfield. The revised 2014 Airfield Improvement project will replace
approximately twelve deteriorated panels surrounding the North Satellite and approximately
fifteen deteriorated panels located on Runway 16C/34C. One additional panel that recently
became distressed will also be replaced and others may be necessary if encountered during the
duration of the contract work. 
Staff has determined that the funds previously authorized by the Commission for the 2014
Airfield Improvement project are sufficient for the completion of this project. No additional
fund authorization is being requested. 

Template revised May 30, 2013.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Cancel the bid and re-bid under the assumption that additional contractor
interest can be achieved. This alternative assumes that future contractor outreach might have
better results than the previous effort. Although there was some evidence of other contractor
interest in performing the work, the time involved in re-advertising the project would result in
the timing of the work coinciding with the seasonal inclement weather. This could result in the
work not being able to be performed and significant impact to airfield operations. This is not the
recommended alternative. 
Alternative 2)  Accept the bid and authorize the execution of the major public works contract
with the sole responsible bidder. This alternative will prevent impact to airfield operations and
allow the work to be completed before the seasonal inclement weather.  This is the
recommended alternative.
