Centerplan Construction Co., the fired developer of Dunkin’ Donuts Park, must pay $39 million to Arch Insurance, the company that guaranteed the stadium’s completion after Centerplan was dismissed, under a decision issued by a federal court judge Wednesday. Centerplan was fired by the city in 2016 after missing two key deadlines to complete the ballpark. Hartford also ended an agreement with Centerplan that would have allowed them to build housing, retail and office space on properties surrounding the stadium. The company sued the city for wrongful termination. It is seeking $90 million in damages.
