Suffolk Construction is dangling a bid package featuring more than $1 billion in subcontracted services and supplies needed to help the general contractor complete a $2.1 billion resort casino on the Mystic River in Everett.

Wynn Resorts announced the bid opportunities on Wednesday, calling it “among the highest ever issued for any private, union-built, single-phase development in the history of Massachusetts.” Companies interested in bidding were urged to email wynninfo@suffolk.com.

“Wynn is absolute in our commitment to keep as much spending as possible close to home during our nearly three-year construction phase, particularly with minority, women and veteran-owned vendors,” Robert DeSalvio, president of Wynn Boston Harbor, said in a statement. “We particularly want local vendors and workers to step up and play a big role in building Wynn Boston Harbor.”

The endeavor pushed by billionaire Steve Wynn touts itself as “the largest single-phase construction project” in state history.

Wynn, which recently prevailed in a legal challenge from Somerville and held a construction kickoff event last Thursday, estimates the construction project on the polluted banks of the Mystic River will generate 4,000 union jobs.

The casino-hotel complex could be the third casino venture in the state to offer legitimate table games. The Mashpee Wampanoag Tribe, which is facing a legal challenge to its federal reservation, has said it expects to open a portion of its planned Taunton casino by next summer. MGM Springfield, which has begun work on its site, plans to open in September 2018. Wynn anticipates opening the doors to its resort in June 2019.

Plainridge Park Casino, a slots parlor in Plainville, opened last year. Wynn’s construction plans coincide with a sustained boom in Greater Boston development, as construction crews have reshaped Boston’s Seaport, Cambridge’s Kendall Square and Somerville’s Assembly Square, among other neighborhoods.
