AGS was responsible for utility relocation, paving, grading, and geotechnical engineering for 55,000 square feet of building addition and renovations at San Francisco International Airport to improve the customer experience for travelers at Terminal 3.

Civil services included site investigation and drawing review; preparation of on-site grading and pavement plans; delineation of utility relocations, determination of site demolition plan, preparation of layout and paving plans, erosion control plans, and landside sidewalk/curb plan and construction details; writing of specifications; and design services during construction.

Geotechnical services included field exploration, laboratory testing, analysis and preparation of geotechnical report.

The building expansion is on the airside of Terminal 3. AGS designed utility relocations for sanitary sewer storm drain and water mains and coordinated with the MEP consultants and architect regarding the proposed locations for electric, communication, gas, and fuel lines, and footings for proposed passenger boarding bridges.

The paving plan was designed to accommodate airplane movement and parking and baggage handling vehicles. AGS also prepared a horizontal control plan for proposed aircraft pavement marking and striping.

The design of Terminal 3 East proceeded while construction was underway at adjacent T3 Boarding Area E (BAE), requiring additional coordination with the BAE consultants and contractors.

This project comprised the complete reconfiguration of the Terminal 3 East facility, resolving passenger circulation and queuing issues, provided for a 30-40 year renewed useful life to the facility, and furthered the Airport’s strategic objective of achieving a fully seismically upgraded facility in a thoughtful and comprehensive manner.

The Terminal 3 East Improvements project upgraded the existing security checkpoint area to meet the standard of quality set by the design, amenities, and level of service of the T2 terminal.  This phased project opened on schedule and achieved LEED Gold certification.
