ACTION REQUESTED:
Request Commission authorization for the Chief Executive Officer to issue Change Order #023
for the North Expressway Relocation, Phase 1, Final Paving Landscaping and Reclamation
Project for a time extension of 75 days to the contract completion date of April 27, 2011, and in
the amount of $32,990. 
SYNOPSIS:
Towards the end of the original construction contract duration, it was discovered that the
planting schedule in the contract documents contained an error in the number of groundcover
plants that were needed at the new entry to the Airport. An additional 1,912 plants were needed
to provide proper groundcover on the east and west side of the southbound Airport expressway at
the new clock tower and entrance sign feature. A change order is required to compensate the
contractor for the actual costs incurred to provide and install the plants in the amount of $32,990
and a time extension of 75 calendar days to price and negotiate the change order, order and
deliver the plants, and complete the installation of the plants.
The funds to pay for this change order come from the project construction contingency funds
previously authorized. No additional fund ing is being requested as a result of this change order.

BACKGROUND: 
This project is the last phase of a multi-phase program to reconstruct the North Airport
Expressway and extend Light Rail Transit (LRT) to the Airport in collaboration with Sound
Transit. This project includes final paving of ramps near the parking garage entrance and the
Airport LRT station, landscaping, an art feature and clock tower at the Airport north entrance,
reclamation of staging and work area and miscellaneous work omitted or deferred from previous
North Expressway Relocation Phase 1 contracts. This project completes the Port's obligation to
Sound Transit to facilitate extending LRT to the airport and the City of SeaTac for landscaping
of Port property and restoration of facilities along city streets.
The new entry feature to the Airport is a key component to this contract. It includes a new clock
tower, and art features that include landscaping as part of the design element. It was discovered
very late in the project that the contract documents did not show the correct number of
groundcover plants to be installed in the entry area. Landscape installation is usually one of the
final components installed on a project so it is not unusual that this error was found very late in
construction. The Port requested a cost proposal for this work that originally came in much
higher that the Port anticipated. This original cost proposal included costs for extended
contractor overhead to stay on the project longer to complete the work.
The Port has not agreed to pay the contractor any extended overhead costs at this time as the 
contractor has not submitted the contractually required time impact analysis. The Port
negotiated with the contractor until September and agreed to pay direct costs in the amount of
$32,990 for this change and to extend the contract completion date to April 27, 2011 when the
work associated with this change order was completed. Once all remaining design and
construction issues have been resolved on this project, the Port will be able to address and
reconcile any additional compensable or excusable time impacts. This includes resolution of the
issues of additional contractor overhead costs, Port liquidated damages and final contract
duration.
FINANCIAL ANALYSIS: 
The funds to pay for this change order are part of the project construction contingency funds that
were included in previously approved authorizations. No additional project funds are being
requested as a result of this change order.

construction bids, award the contract and construct the NER Phase 1 project consisting of final
paving, landscaping and reclamation (CIP C800034). The estimated cost of this project,
$5,880,000, is within the previously authorized budget.

Executive Officer to execute an Interlocal Agreement with Sound Transit to establish the real
property, financial and construction arrangement for the construction of the Airport Link Project.
The Commission authorized an additional $61,411,000 for a total project-wide authorization of
$78,282,000 and authorization to enter into contracts estimated at $165,000,000.
