Two developers are bidding for the right to build hotels on property next to the Boston Convention & Exhibition Center in South Boston. Commonwealth Ventures of Boston is proposing to construct 450 rooms on property along D Street owned by the Massachusetts Convention Center Authority. Carpenter & Co. of Cambridge is proposing to build 500 rooms.

The bids came in response to a request for proposals issued last year by the MCCA, which is seeking to encourage the development of mid-priced hotel rooms near the BCEC.

James Rooney, executive director of the MCCA, has said additional hotel rooms are needed to serve large trade shows wishing to hold events at the South Boston convention center. The effort to build mid-priced hotels is part of a broader expansion effort that could include another large headquarters hotel and a doubling of the center’s exhibit space.
