South Terminal Expansion Project (STEP)
Seattle, WA

PROJECT DESCRIPTION:
The South Terminal Expansion Project (STEP) was a 900,000 SF project that included fourteen aircraft gates, a large baggage handling area, a new concourse, and a new office tower. The facility included an advanced Aviation Voice Paging System and an extensive Fiber Optic Cabling system.

COMMISSIONING SERVICES:
Working as a sub-consultant to Engineering Economics, Inc. (EEI), ACSI was responsible for the commissioning of the Fire Alarm System and all of the Division 17 systems including the Premise Wiring Distribution System (PWDS), the Broadband Headend and Distribution System, and the Aviation Voice Paging System (AVPS). The services commenced with a complete design review followed by the development of a commissioning plan, a review of the contractors’ submittals, and preparation of system test plans. The low-voltage commissioning tests proceeded as soon as the related systems were made available. These included CCTV, fire alarm, voice paging, flight information, terminal data, vender information, and security systems.

UNIQUE SERVICES:
As a provider of commissioning services, ACSI is uniquely able to foster synergy and coordination among the numerous participants while maintaining its objectivity. These departments included IT and communications groups, the facilities and maintenance group, the Port Fire Department, the design team, the independent system vendors, the construction forces, and the project management team.  A number of potentially troublesome problems were identified and rectified early in the project, thus enhancing the testability of the low-voltage systems and avoiding future installation difficulties.
