Stanley Consultants, an Iowa-based global consulting engineering firm, recently acquired Denver’s Hartwig & Associates Inc., an engineering and construction management services firm that serves the Colorado transportation marketplace.

The acquisition gives Stanley Consultants a foothold in the Colorado transportation sector that it did not previously have.

Marvinetta Hartwig founded Hartwig & Associates Inc. in 2001. Under her leadership, it has grown to nearly 30 professionals offering services in civil, structural, traffic and water-resource engineering and construction management and inspection. Hartwig & Associates’ client portfolio includes the Colorado Dept. of Transportation.

“This deal gives us the ability to pull from national resources [at Stanley Consultants],” Hartwig said. “And to service bigger projects.”

The Hartwig & Associates staff will integrate into Stanley Consultants’ Denver office as the Transportation and Construction Management departments. Hartwig will lead around 35 people in the firm’s new Denver transportation group.

“The similarities in our company cultures is what attracted us to Stanley Consultants,” Hartwig said. “Our values and standards for quality, reliability and client service closely mirror those of Stanley Consultants.” 

The acquisition raises the number of Stanley Consultants’ Colorado employees to well over 200, making it one of the larger engineering firms in the state. The firm’s Denver office, opened in 1982, provides planning, engineering and construction services in power generation, power delivery, plant and building services, urban planning, and environmental to clients around the world.

The Hartwig acquisition adds a full suite of transportation services to the company’s portfolio. The firm’s transition to Stanley Consultants should be complete by April 4, Hartwig said.

“We believe there is significant value to our clients by combining the skills and resources of both firms,” said Gayle Roberts, president and CEO of Stanley Consultants. “Hartwig’s exceptional reputation and project portfolio paves the way for Stanley Consultants to expand into the Colorado transportation marketplace. Services to Hartwig’s clients will be expanded through Stanley Consultants’ capabilities, specialized expertise and global resources.”

Headquartered in Muscatine, Iowa, Stanley Consultants employs 1,100 professionals in 30 offices around the world and is ranked by ENR among the nation’s largest engineering firms.
