Minnesota's 3M is building a $150 million, 400,000 square foot research and development center on its Maplewood campus.
The Star Tribune reports construction on the four-story state-of-the-art building began on Wednesday. The construction is expected to last two years.
The newspaper said that the facility, to be tagged with the no-frills name of Building 280, will provide technology research for three of 3M’s five businesses: electrical and energy, safety and graphics, and industrial.
The city of Maplewood supported tax-increment-financing for the project, which the Legislature approved in May.
Last month, 3M announced plans to expand its manufacturing plant in Brookings, S.D.
