New Concourse For San José Airport

Recent Topping-Out Ceremony was a milestone for overall expansion project
August 11, 2010

The Norman Y. Mineta San José International Airport (SJA) is undergoing what it calls a "Monster Project"; that is, a multi-faceted $1.5-billion upgrade that will bring it up to par with the best airports in the country. Already runways have been extended, and some facilities upgraded.

The first phase upgrade began in 2004 and is scheduled for completion by 2010. It includes a new 380,000-square-foot North Concourse, a new Terminal B, the demolition of Terminal C, and upgrades to Terminal A. Roadways at and to the airport will be upgraded, and a new 3,400-space parking garage will be built. Terminal A improvements and Terminal B construction will start in 2008. Terminal C is set for demolition in 2010.

Recently the new $355-million North Concourse celebrated its midway topping out with a dedication by the airports' namesake, Norman Y. Mineta, former mayor of San José, as well as former U.S. Secretary of Transportation. The new facility will eventually feature nine new commercial aircraft gates, passenger hold rooms, state-of-the-art baggage security systems, and other passenger amenities. The North Concourse should be ready for air traffic by late 2008, according to Gary Lamb, project executive with Gilbane Building Company, the construction manager.

New Concourse Construction

Lamb says of the airport construction site, "It's a tight site — every day is kind of like a 'Rubik's Cube' to coordinate working with the array of contractors and the subs." Tony Kostakis, Gilbane construction manager for the new concourse, described some of the challenges of the early construction:

"The basement area was excavated approximately 25 feet below grade. We off-hauled 150,000 cubic yards to a city-owned site." Then there was the critical issue of keeping the water table at bay.

"The dewatering consisted of 54 deep wells that pumped 700 million gallons of water over a 700-day time period, through 12-inch pipe that ran the entire perimeter of the excavation, into five each Baker tanks. These filtered the water before it was transferred 'clean' into the Guadaloupe River," he said.

"The waterproofing consisted of a Laurenco three-ply waterproofing membrane with a mastic adhesive. The waterproofing membrane made the entire basement level like a bathtub/water balloon. The waterproofing application was below the concrete and then continued to the first floor slab, totally enclosing all the concrete."

The basement floor is a 3-foot-thick reinforced concrete slab. The walls are 18-inch-thick double mat reinforcing with shot-crete walls.

Other Challenges

Kostakis said there is the normal fleet of excavators, backhoes, man-lifts, concrete pumps trucks, cranes, skid steers, etc. being used, but, "The proximity of the cranes used required a permit (7460) issued by the FAA," he said. "A major challenge was that the building connects to the two adjacent buildings (north and south). This necessitated either night-time airside deliveries, to not interfere with aircraft traffic movement, or else the construction of three shored bridges over the first-floor concrete deck. We chose the bridge method. These were removed as the structural steel was erected from north to south."

Kostakis said the entire project is proceeding on a fast-track schedule.
