(Atlanta Business Chronicle) The state agency overseeing the construction of the new Mercedes-Benz Stadium knew in February there were possible issues that could delay its opening, 11Alive's partners at the Atlanta Business Chronicle report.

That was when the Atlanta Falcons approached members of the Georgia World Congress Center Authority (GWCCA), the state agency that will own the project, to inform them of potential construction delays. The possible complications stemmed in part from the one-of-a-kind retractable roof, GWCCA executive director Frank Poe said in a phone interview with Atlanta Business Chronicle on Wednesday.

Poe’s timeline offers more context to the announcement April 18 that the opening of Mercedes-Benz Stadium would be delayed again until Aug. 26, when the team is set to play its first pre-season game.

It was the latest delay for the stadium, where both the Atlanta Falcons and Atlanta United soccer team would play home games starting this year. The building was supposed to host an Atlanta United game on July 30. Early projections had the stadium opening around March.

The Falcons also said this week the demolition of the Georgia Dome would be delayed as an “insurance policy.”
