DEADWOOD — The Deadwood City Commission awarded two retaining wall contracts Sept. 3 following a bid opening held Aug. 27, for a combined cost of $298,000.
RCS Construction was awarded the bids for both walls.
One at 291 Williams St., had a base bid of $195,800 and an alternate one bid of $25,000. City staff recommended the commission reject the alternate one bid.
Deadwood Public Works Director Bob Nelson, Jr. said there was one bid on this wall project.
Commissioner Gary Todd asked if work on the wall would start this fall.
“We won’t have a contract in place until (Sept. 16.), and we give notice to proceed immediately after that,” Nelson said. “Oh yeah, we have to. The wall’s moving.”
The other wall, located at 562 Williams St., was awarded for a base bid of $93,600.
“This is a residential program wall through historic preservation, below engineer’s estimate. I don’t know what the equation is as far as city portion, but the recommendation is to proceed,” Nelson said.
Martinisko said her only concern is that they are below engineer’s estimate.
“By a chunk,” Martinisko said. “Have we, in the past, had a lot of change orders from RCS on walls?”
Nelson said he didn’t know right off the top of his head.
“I think it matters where the construction is,” Nelson said. “The stable soils versus…”
Ruth said it might be a mobilization cost savings, due to the fact that the walls are on the same road.
“My guess is that they planned to win both,” Nelson said.
Todd asked what the engineer’s estimate was on the 562 Williams St. wall.
“$101,125,” Martinisko said.
A second bid of $100,750 from CAI2 was also submitted on the 562 Williams St. retaining wall, with staff recommendation to award the lower bid.
