The Dietze Construction Group, a building contractor in the Washington, D.C. area, filed May 18 for protection from its creditors in U.S. bankruptcy court in Virginia. The company had planned to sell itself to Suffolk Construction Co., a much bigger Boston-based contractor, but the announced deal apparently had never been completed.
Based in Ashburn, Va., Dietze listed numerous creditors and several million dollars in unpaid debt. The creditors included concrete, electrical and mechanical subcontractors or suppliers.
