COMMISSION AGENDA MEMORANDUM Item No. 4b ACTION ITEM Date of Meeting December 5, 2017 DATE: November 17, 2017 TO: Dave Soike, Interim Executive Director FROM: Ralph Graves, Senior Director, Capital Development Janice Zahn, Assistant Engineering Director, Construction Services SUBJECT: Vertical Conveyance Modernization Project Change Order #109 (CIP #C800251) Amount of this request: NONE Total estimated project cost: $5,104,121 ACTION REQUESTED Request Commission authorization for the Executive Director to execute Change Order 109 to Contract MC-0317730, Vertical Conveyance Modernization Phase 1 at Seattle-Tacoma International Airport, to extend the contract duration by 168 calendar days and for the deductive amount of $10,000. No additional funds are being requested. EXECUTIVE SUMMARY This project provided complete modernization of eight elevators, added hydraulic cooling units to twelve existing elevators in the Main Terminal and replaced four escalators at the north end of the Main Terminal. The original construction contract was $4.6 million. The execution of this change order reconciles all contract time and cost issues with the contractor, Absher Construction, and results in a cost credit back to the Port of $10,000. No additional funds are needed. JUSTIFICATION The existing elevators included in this project were installed in the 1960's and 1970's and the existing escalators were installed in 1970 and upgraded in 1990. Due to their age and technology, the controls, drives and door actuators of these elevators and escalators became uneconomical to maintain. Installation of hydraulic oil cooling packages improved the reliability of the existing hydraulic elevators by eliminating or decreasing outages due to overheating, thus improving the Airport's experience for passengers who are unable to use the stairs or escalators. Below is a listing of the elevators and escalators completed in this contract. Template revised September 22, 2016.

Through the Change Order process, 76 days of time were added to the contract for a Substantial Completion date of July 5, 2016 (41 plus 35 days on 2 Change Orders). The Contractor experienced labor and production issues which delayed the project completion by 168 days until 12/21/2016, when Substantial Completion was accomplished. Post Substantial Completion, design errors were identified during a Labor & Industries permit inspection on elevator MT-3, which was required to be corrected. This Change Order settles the final cost and time due to delays caused by both the Port and the Contractor. Scope of Work Work included development of infrastructure to modernize seven existing elevators and four escalators, and retrofit twelve hydraulic elevators with hydraulic oil cooling systems.
