Autodesk Inc. (San Rafael, Calif.) has agreed to acquire Constructware (Alpharetta, Ga.), a 65-person software developer that focuses on web-based, construction-oriented collaboration services. Autodesk plans to combine its web-based design and project management service, Autodesk Buzzsaw, with its Constructware counterpart.

For the near future, Constructware will continue operations and retain most of its staff. The company had a strong 2005, with sales up 70 percent compared with 2004 and a 250-percent increase in new business. Autodesk Buzzsaw has more than 137,000 users while Constructware has more than 29,000 users. Autodesk expects to close the deal in 30 to 60 days, but already has received approval from its board of directors. No decision has been made yet regarding the Autodesk and Constructware brands. They will both be maintained for the time being. Constructware was founded in 1994.
