A Dutch-owned energy services provider is consolidating and relocating its Western New York operations into a single facility in Amherst.

Applus+ RTD USA will move its Eastern division headquarters office at 37 Franklin St. in Buffalo and its operations facilities at 4400 Broadway in Depew into a 35,000-square-foot freestanding building owned and managed by Zaepfel Development Co. at 80 Lawrence Bell Drive, said David Schiller of Pyramid Brokerage Co. of Buffalo, who worked with Applus+.

The business is part of a global firm that offers testing, inspection and certification to the energy, utility and infrastructure industries, such as pipelines, refineries and storage facilities. The newer and larger facility is “better equipped for meeting the needs of the growing business,” the company said in an emailed statement. The Depew site housed 80 employees in 22,000 square feet, while the downtown headquarters had 20 workers in 6,300 square feet.

Applus+ has offices across the country, including Rochester, Syracuse and Albany. Its local operations used to be part of Quality Inspection Services Inc., until Applus+ RTD bought it in 2010.

The company, which also took additional space in the Syracuse area, considered several local options for the move. “The industrial market is relatively tight, but there was good competition among several developers for this lease,” Schiller said.
