Oceanside, Calif.— DBM Contractors, Inc. performed emergency landslide repair for the Sprinter Mainline in the city of Oceanside. The slide occurred during earth moving to build a retaining wall at the base of a steep slope adjacent to the new Sprinter Mainline. The slope stabilization project required installing four rows of permanent anchors, with each row containing 43 anchors ranging in length from 90 feet to 115 feet along a span of 350 feet. The lowest row of anchors was in very close proximity to the utilities on the site requiring diligent care and some modifications of the work. The seven-strand permanent anchor tendons were locked off at 240 kips. Anchor reaction grade beams were built of reinforced shotcrete measuring 6 feet high and 2 feet thick.

The project site was very limited by its close proximity to an active rail line and the presence of threatened wildlife species in the area. The two-month completion schedule was set due to both environmental permitting and the rail operating schedule.

The Sprinter Mainline is owned by North County Transit District. The general contractor was West Coast Rail Constructors (a joint venture of FCI Constructors and Fluor).

Founded in 1949, DBM Contractors, Inc. concentrates in specialty geotechnical construction and design-build heavy civil construction, emphasizing drilled foundation support, earth retention, slope stabilization, and ground improvement.
