Though it can’t promise the intrigue of an “Indiana Jones” movie, the U.S. Navy can promise work in the archaeological space.

Two San Diego County small businesses — ASM Affiliates Inc. of Carlsbad and Tierra Environmental Services Inc. of San Diego — are among five companies on a short list to help the U.S. Navy evaluate cultural resources during the preparation of environmental impact documents.

The Navy’s building arm, the Naval Facilities Engineering Command Southwest, said recently that it selected the five to compete for task orders. No task orders have been awarded yet.

The five contracts are good for one year and each has four option years. The maximum value of all the contracts put together is $50 million.

Under the deals, contractors will furnish labor, management, supervision, tools, equipment, materials, travel, lodging, food and transportation to provide cultural resources-related studies as well as historic and archaeological documents.

The Navy estimates that 94 percent of the work will be done in California.

Seven companies bid on the work.
