The National Football League’s Baltimore Ravens are planning a $430-million renovation of their home field, M&T Bank Stadium. The Maryland Stadium Authority, which manages the facility, recently selected Gilbane Building Co. as construction manager for the project.

Gilbane was one of nine firms shortlisted in response to a request for qualifications earlier this year, stadium authority records show. The authority’s architect and engineer for the project, Gensler Architecture, Design & Planning P.C., also beat out nine other shortlisted firms.

The plans call for the service level around the 25-year-old, 71,000-seat stadium to be dug out in order to add more fan space. There would also be additions to the north and south entrance plazas, construction of a two-level social space on the east side of the stadium and improvements to various other fan spaces inside the stadium. In addition to the work on fan-facing areas, Sashi Brown, the Ravens president, said in a statement that the plans include “important infrastructure investments to secure the stadium’s long-term viability.”

Gilbane previously worked on smaller improvements to the stadium between 2017 and 2019, such as addition of new corner suites and installation of new video displays. The contractor has also previously worked with the stadium authority on projects including the Baltimore Convention Center, the University of Maryland XFINITY Center and the relocation of the left field wall at Oriole Park at Camden Yards. 

“Our focus is on a strong collaboration with the stadium operations, Gensler, and our trade partners with a commitment to driving economic inclusion throughout construction,” said Ted Holt, senior vice president and Maryland business leader at Gilbane, in a statement. 

Work is scheduled to start next year. Pieces of the project are scheduled to complete between later next year and 2026. 

The funding for the renovations come from the state as part of $600 million set for stadium improvements in the Ravens’ recent lease renewal, which lasts through at least the 2037 season. The team has not announced plans for the remaining $170 million.
