Trimble Navigation Ltd., a location and positioning software company, built its new 125,000-square-foot building in Westminster, with space for as many as 570 employees, because it’s growing and also to demonstrate the company’s technology.

Trimble (Nasdaq: TRMB), based in Sunnyvale, Calif., currently has 470 employees in its Colorado office. The company held a grand opening Monday for the four-story building, located at 10368 Westmoor Drive.

Trimble’s CEO, Steven Berglund, said the new building “provided us with an opportunity to showcase our office-to-field Connected Site solutions during the planning, construction and operational phases.”

Employees working at Trimble’s new building focus on marketing, testing and applications engineering in the construction, surveying, agriculture and mapping & geographic information system (GIS) markets. Trimble said it hopes the building will get a “gold” certification from the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program, which promotes sustainability.

JE Dunn Construction Co., based in Kansas City, Mo., with an office in Denver, was the general contractor for the project. OZ Architecture of Boulder designed the building.

Trimble said that JE Dunn and its subcontractors used Trimble software to speed up construction in several ways.

• Site excavation was completed four weeks, or 30 percent faster than traditionally anticipated.

• Structural steel shop drawing review time was 33 percent faster than comparable office buildings completed by JE Dunn in 2012.

• Achieved 100 percent accuracy of embed placement and 50 percent reduction in structural requests for information (RFIs).

• Final column building placement was within ¼-inch tolerance.

• 30 percent reduction in request for information about mechanical, engineering and plumbing issues during construction, which resulted in finishing the mechanical, engineering and plumping layout and hanger installation four weeks faster than projected.

• Field layout was reduced from three weeks to seven days.

“Our partnership with Trimble was a natural one for us as Trimble and JE Dunn have a shared focus on driving results through technology, fostering collaboration and lean practices,” said Terry Dunn, JE Dunn president and CEO.

Trimble, founded in 1978, opened its Colorado office in October 2000 with 43 employees at a 29,000-square-foot office in Westminster’s Church Ranch Office Center.

Gov. John Hickenlooper, Jefferson County Commissioners Faye Griffin, Donald Rosier and Casey Tighe, and Westminster Mayor Nancy McNally attended the grand opening of the new building.

“We welcome Trimble and its 475 employees to their new Westminster Campus,” Hickenlooper said. “Colorado’s business-friendly environment makes our state a natural fit for international technology and services companies. Our location and talented high-tech workforce is building on Colorado’s reputation as an international hub for business.”
