Two companies receive military contracts worth potentially hundreds of millions

Advent Environmental Inc., the Mount Pleasant-based environmental consulting firm, was one of 10 companies earlier this month to be included in a contract worth up to $350 million to provide environmental support, restoration and remediation for the U.S. Air Force.

The contract, part of the Air Force’s ECOS09 program, covers myriad tasks, including munitions disposal, minor construction, demolition and repair, and the operation and maintenance of remedial groundwater and soil systems, company officials said.

“It’s pretty large scope to be able to do a lot of different things,” said Mark Stoker, senior project manager with Advent.

Work done under the contract will take place at Air Force installations and other sites based on technical and regulatory requirements. The contract’s ordering period ends Nov. 6, 2014, though work on projects can continue for 24 months after that date.

Advent provides services in restoration, munitions cleanup, compliance, pollution prevention, conservation, and engineering and support services. The company earlier this month was acquired by Springfield Va.-based Versar Inc., a professional services firm that specializes in security and defense programs.

SAIC to do work in Charleston

Science Applications International Corp., a Virginia-based scientific, engineering and technology applications company, was earlier this month awarded a $6.3 million contract by the U.S Navy for tactical mobile systems engineering and technical support services.

The contract contains options that, if exercised, would bring its value to $108 million. Sixty-five percent of the work will be performed at the company’s facilities in Charleston, while the remaining 35% will be done in Patuxent River, Md.

Work is expected to be completed by December 2010. If options are exercised, that deadline could extend as far as December 2014.

The contract will allow various Navy offices to acquire technical services, equipment, system integration, assembly and testing, installation training and maintenance, and logistics products in support of its TacMobile program.
