Jack Klugmann, the president and founder of Accurate in New Jersey, which purchased the property earlier this year, said his company has done many different groundbreakings, but it is rare he and his colleagues are excited to be attending one. Shovels dug into earth as town and state officials, as well as developers from Accurate, marked the beginning of work on the mixed-used project at the Fairfield Metro Station. The development aims to build 357 apartments, a 118-room hotel, 70,000 square feet of office space and 40,000 square feet of retail space. Development of the site has long been a topic of debate between Fairfield officials who say the site, the former foundry off lower Black Rock Turnpike, has been dormant for too long. Blackrock Realty contributed $5.4 million to the construction of the station in exchange for the rights to build its initial commercial and residential project connected to the station.
