Project Overview

The Vertical Conveyance Systems Upgrade program includes the modernization or addition of more than thirty elevators and escalators throughout Seattle Tacoma International Airport. OAC assembled a select team to execute these projects in a Construction Management-led design delivery. OAC recognized the biggest challenges associated with these modernizations were in the logistics, phasing, organization and communication. With this in mind, OAC formed an experienced construction management leadership team and partnered with industry leaders, Lerch Bates and SRG Partnership, to provide the vertical circulation and architectural design components of the program. OAC worked closely with the Port of Seattle to sequence the projects and develop the individual bid packages for construction.

Central Terminal Freight Elevators
This project includes two new, 10,000-lb capacity freight elevators located symmetrically on each side of the full-height curved glazed curtainwall of the airport’s Central Terminal (CTE). These new four-stop freight elevators provide direct access to the basement, ramp, ticketing and mezzanine levels, which provides enhanced capacity to concessions tenants and enables future growth for food service businesses. The project required significant utility coordination and close synchronization with multiple tenants.

Aero Phase 1 – Main Terminal
This project entailed work on twenty elevators and four escalators in the main terminal. Design included the complete modernization of seven, 50-year-old elevators and oil cooler upgrades to existing hydraulic units. Extensive site surveys were required, along with tight coordination with the Port Infrastructure and Operations groups.

Aero Phase 2 – South Satellite
This project involved the design of two new elevators, and the modernization of two existing elevators in the airport’s South Satellite. The addition of the new elevators required the relocation of the TSA checkpoint outside of the US Customs Federal Inspection Services area. The design of the new elevators and relocated checkpoint solved two key operational challenges within the facility: accessible vertical circulation with redundancy and streamlined processing and wayfinding within the TSA checkpoint.

Concourse C Sloped Walkways 
This project added external sloped walkways and passenger elevators at Gates C2, C12 and C14 on Concourse C as part of the Alaska Airlines Group (AAG) Northstar project. Horizon Airlines, their regional carrier, was expanding existing operations on Concourse C, driving the need for improved passenger mobility. OAC’s team worked closely with AAG and the Port to design transparent weather-protected glass enclosures that wrapped the sloped walkways and new elevators at each gate. The new walkways are easy to navigate and significantly upgraded the passenger experience for Horizon Airlines.
