Brett Jewkes, AMB Group’s senior vice president and chief communications officer, declined to speculate on such questions, saying an update on the project schedule is expected in about seven to 10 days.

Mercedes-Benz Stadium’s first scheduled event is an Atlanta United soccer match on July 30, followed by two more soccer matches in August and two Chick-fil-A Kickoff college football games in early September: Alabama vs. Florida State on Sept. 2 and Georgia Tech vs. Tennessee on Sept. 4. Dates for Falcons home games are expected to be announced next month by the NFL, along with the rest of the league’s 2017 schedule.

The earlier delays caused Atlanta United to schedule the first eight home matches of its inaugural season at Georgia Tech’s Bobby Dodd Stadium. It isn’t known if Tech could accommodate matches after July.

One obvious candidate to host football games if the new $1.5 billion stadium isn’t ready would be the Georgia Dome, which officially closed after a Monster Jam trucks show March 5 amid plans to demolish it this summer.

A spokeswoman for the Georgia World Congress Center Authority, which operated the Dome and on whose campus the new stadium is being built, said preparations for demolition have begun, such as removing the turf. But “until the Dome is demolished, it could be utilized,” Jennifer LeMaster said Wednesday.

GWCCA Executive Director Frank Poe said in a statement that the state agency “has recently been made aware that construction sequencing related to Mercedes-Benz Stadium’s retractable roof is currently being evaluated.”

Echoing the timetable provided by the Falcons, Poe said GWCCA officials “anticipate having an update on the project schedule in the next seven to 10 days.”

The first-of-its-kind roof consists of eight petals, each to be installed in four pieces. The roof is designed to open or close in about eight minutes with what architects have described as a “camera lens-like” effect. A 58-foot-tall, halo-shaped video board will hang from the circumference of the roof opening, encircling the field.

The GWCCA’s latest project status report, dated Feb. 28, did not address the completion date. The report said “the mid-section of the petals on the operable roof are currently being erected” and that installation would continue over the next 30 days on the “operable petal tracks.”
