MEMORANDUM 
COMMISSION AGENDA            Item No.     5a
Date of Meeting        July 7, 2009
DATE:   July 1, 2009
TO:     Tay Yoshitani, Chief Executive Officer
FROM:   Ralph Graves, Managing Director, Capital Development Division
SUBJECT: Change Order # 81 for a time extension of 245 calendar days to the Third Runway
Project 2007-08 Construction / Runway 16C Safety Area Expansion / Lighting Vault Project -
Contract Number MC-0314114
ACTION REQUESTED:
This memorandum requests approval for the Chief Executive Officer to execute Change Order
#81 for a time extension of 245 calendar days at no cost to the Port for the Third Runway 2007-
08 Construction / Runway 16C Safety Area Expansion / Lighting Vault Project.
SYNOPSIS:
The contractor completed the 3rd Runway project for the Port's beneficial use on September 1,
2008. Final project completion and closeout was delayed due to several end user requested
change orders related to the new Airfield Lighting Vault. These change orders required
modifications to the diesel generators and their operations and modifications to the Airfield
Lighting Control and Monitoring System that were identified during the burn-in period. Now that
the change order work is complete, a Change Order to extend the contract's substantial
completion date for the additional contract time is required to implement these changes and to
complete the final testing and Operation and Maintenance manuals. This Change Order is issued
at no cost to the Port.
CHANGE ORDER DESCRIPTION AND JUSTIFICATION: The following information
relates to the pending change order scope and cost:
Change Order No. 081 
Scope of work: Incremental contract established milestone dates were met and the 3rd 
Runway itself was complete for beneficial use on September 1, 2008 as required by
contract. The 3rd Runway was successfully commissioned and placed in commercial
service on November 20, 2008 as scheduled. The original contract completion date was
November 12, 2008. During systems burn-in and commissioning of the 3rd Runway the
Port identified and requested various modifications to the backup power systems and the
Airfield Lighting Control and Monitoring System to improve the functionality of these
systems. These modifications were issued as change orders and the work is now
complete.

These changes also precipitated delays in completion of O&M manuals, and final testing
of systems. Substantial Completion will be achieved before July 15, 2009 and a change
order is required to extend the contract time by the 245 calendar days.
Justification: The modifications to the backup power system and airfield lighting
system were identified during burn-in and were subsequently performed after beneficial
use was successfully achieved on the required contract schedule. To maintain the
warranty, the Port made the decision to have the contractor perform this work.
Therefore, the delay in substantial completion of the project is caused by the Port of
Seattle and a change order must be issued.
Consequences of not proceeding: The project documentation would be incomplete to
provide justification for the contractor exceeding the contract completion date.
FINANCIAL ANALYSIS: This is a no cost Change Order.
CONTRACT INFORMATION: The following information relates to the contract and
competitive award:
