Engineering firms announce expansions

Two Johnson County-based engineering services companies made expansion moves this week.

Terracon announced its second acquisition of the month, this time purchasing Mayes Testing Engineers of Lynwood, Wash. The Seattle-area company has 115 employees, who have all been retained, Terracon said.

The purchase price was not disclosed.

Mayes’ services include special inspections, materials testing, surveys and other consulting for a variety of clients including architects, contractors and structural engineers. The company was formed in 1991.

The acquisition followed a move by Terracon to expand in the Rochester, N.Y., area.

Terracon, which is based in Olathe, is an employee-owned engineering consulting firm with more than 3,500 employees in more than 130 offices.

Terracon said the Mayes purchase was its fifth acquisition in the western United States in the past two years.

“This acquisition allows us to significantly expand our presence and service offering in the Pacific Northwest,” David Gaboury, Terracon’s president and chief executive said in a statement.

Meanwhile, Lenexa-based Shafer Kline & Warren Inc. announced the opening of a new office in Austin, Texas.

The surveying and engineering company said the office will serve the Austin and San Antonio areas, focusing on infrastructure development and energy.
