Workers with Atlas Scaffold of South Charleston showed up two weeks ago to begin constructing scaffolding in the chamber. They plan to finish by Wednesday.
Speaking to the Daily Mail on Friday, Cassis said workers with W Q Watters probably would begin work today on the chamber's arches. They will begin work on the chamber dome once the scaffold is finished.
Most of the furniture has been removed from the room. All the senators' desks and chairs are stored in an adjoining hallway and a reception room near the Capitol's west wing. The desks and chairs are numbered, so all will go back to their original spots.
The Senate President's podium, along with the media desks in the back of the room, is covered with foam sheets and plastic.
Workers lowered the chamber's chandelier last month for cleaning, and left it down so it would be out of the painters' way.
The work should be completed within a month. Cassis said the Senate picked W Q Watters because the company has a lot of experience working around the Capitol.
They recently completed renovations at the Governor's Mansion, and also were responsible for the Senate chambers' cleaning and re-painting back in the 1990s.
"They did it last time, so they know what it entailed," Cassis said.
Scaffolding subcontractor Atlas Scaffold of South Charleston also has experience working around the statehouse, including building stages for the recent sesquicentennial celebration.
