In October 2010, Oakland International Airport (OAK) broke ground on the construction of a 236-foot-tall air traffic control tower and a 13,000 square-foot base building. The new tower, funded through a $33.2 million American Recovery and Reinvestment Act (ARRA) grant, will replace the two air traffic control towers previously used by the airport.

The new tower, expected to be fully operational in 2013, improves the efficiency of air traffic control operations while increasing safety factors and providing the air traffic controllers improved visual contact with both private and commercial planes.

Devcon Construction, among California’s most active and respected construction firms, was awarded the contract to oversee the construction. Dayton Superior joined the project planning efforts by working with the project’s engineering team to develop a wall bracing strategy using Accubrace helical ground anchors and braces.

Accubrace helical anchors were used in place of the deadmen. The system consisted of two pieces — a 7' helical anchor, and a connector. This bracing system achieved the loads required to match the wall brace loads up to 12,000# SWL. The helical anchors installed into the soil provided an economical method for support of the wall braces.
“The Accubrace System proved to be the best bracing solution. It saved money and time, yet offered strength and performance that exceeded expectations,” said Tom Lutge, a structural engineer with Quake Structural Engineering, who assisted in the installation of the helical ground anchors. “The real test came when during construction, the San Francisco Bay area experienced a wind storm with gusts nearing 100 mph. The next day when we checked the site, the Accubrace system had withstood the significant force. Not one anchor or brace failed.”
