SaLUT was incorporated on September 1, 1976, in Maryland. It began as a small research firm dedicated to improving agricultural production in the Third World. A small engineering component was added in the 1980s.

The company then changed its focus to becoming a research and applied civil engineering firm. SaLUT continued to grow by acquiring other business ventures, and gradually expanded its services offerings.

SaLUT received its first industrial hygiene contract with the U.S. General Services Administration in 1989, whom we continued to support for 20 years. From 1997 through 2010 we worked in more than 160 countries for the U.S. Department of State, twice receiving the Assistant Secretary's Award for Excellence. Our other long-term clients have included Naval Facilities Engineering Command Mid- Atlantic, the Army Corps of Engineers (Baltimore, New Orleans, Honolulu, and other Districts), the District of Columbia, the Department of the Treasury, numerous state and local government agencies and school districts, and private industry. Industrial hygiene now accounts for approximately 40 percent of SaLUT's revenue.

With the purchase of EastStar Engineering in 1994, SaLUT added a significant environmental engineering component, providing environmental support to the Metropolitan Washington Airports Authority, US Army Corps of Engineers Baltimore District, the Environmental Protection Agency, National Institutes of Health, The Pentagon, and numerous other clients. For SunTrust Bank and other financial institutions SaLUT completed hundreds of Phase I and II Environmental Site Assessments (ESAs).

SaLUT received its first contract in 2006 for environmental engineering and industrial hygiene services with the DC Public Schools. This service has continued under a series of awards from DC Department of General Services for comprehensive environmental and industrial hygiene support through SaLUT's US General Services Environmental Schedule contract.

In 2009, SaLUT was awarded a contract by the Bureau of Indian Affairs nationwide NEPA and construction project management programs.

NFE, Inc. was acquired in 1993, with a large construction inspection activity in Boston, Massachusetts and a drilling operation in Baltimore, Maryland. TLB, Inc., a firm that specializes in, Geotechnical engineering, materials analysis, drilling, and corrosion engineering capabilities was purchased in 2012.

Since 1992, construction project management has been a major component of SaLUT’s business base, including approximately 14 research and technology transfer contracts with the Federal Highway Administration from 1994 through 2008.
