Hard hats, safety vests and steel-toe boots will soon be replaced by up-dos, dark jeans and dancing shoes.

Construction on The Dome, the soon-to-open entertainment venue that’s part of Virginia Beach’s $350 million Atlantic Park project on 20th Street, is nearing its finish.

“We’ll be ready for May 4,” Matt Rogers said, referring to when the band Three Dog Night will play the venue’s debut concert .

Rogers, a regional vice president of venue operations for Live Nation Entertainment, joined media members Thursday on a tour of The Dome. Live Nation will operate the city-owned venue in partnership with Virginia Beach.

Reporters, camera crews, Live Nation representatives and city officials — wearing reflective neon vests and protective eyewear — formed a long train that snaked into the bowels of the still-unfinished building.

Led into the music hall, the visitors paused and stood on The Dome’s stage, looking out at a large auditorium with the capacity to seat 3,500 people for live performances, conventions or parties.

The Dome booked its first wedding for June, but on Thursday, construction crews were busy installing railings on a back, third-story mezzanine that will seat general-admission audience members.

“We’re down to the architectural finishes,” said Chuck Arthur, the general superintendent for the construction project.

The sounds of electric drills buzzed from the direction of mezzanines — to the left and right of the stage — that’ll be filled with cocktail tables for VIP ticket holders.

Next, the tour progressed to the building’s lobby with a parametric wall — planks of composite wood cut and designed into the shape of a wave — before visitors stepped into the sun and glanced at what will be an outdoor seating area.

The back wall of The Dome’s music hall will come equipped with hangar doors, that when open, will provide a direct line of sight to the stage for any of the up to 1,500 people who may be enjoying the outside seating.
