The effort to fix the Riverton Branch Library's leaky roof and its drainage problems suffered a setback when only one company submitted a bid by the Aug. 12 opening.
The one company that did bid wanted to perform only part of the work.
Fremont County Commissioners rejected the bid at their meeting Tuesday, and planners are redesigning the bid and expect to finish it in December.
"I'm at the point where it doesn't really look very feasible to pursue much more this season," Fremont County Library System facilities manager Tom Norwood said.
The building's roof has leaked for decades, officials say, posing a particular threat to the library's paper-based collection.
The drainage around the building draws groundwater to the structure, undermining it, and water on its parking lot builds up and during cold weather freezes, according to reports.
A new timeline from Norwood calls for advertising in January, opening bids in April, awarding a contract in May and finishing the project in November 2016.
The lone bid came from Wyoming Roofing & Supply II from Sheridan. That bid was for work on flat parts of the roof but not others areas. The company also did not propose taking on part of the project that would involve fixing poor drainage issues around the library and in its parking lot.
Seven companies attended a pre-bid meeting, Norwood said.
"I encouraged them to go ahead and bid on the part they considered would be their expertise, but this was the only one who decided to do that," he said.
Few companies were likely interested because the project is complicated, and it is hard to evaluate the cost.
"They don't know underneath how much damage there is," Norwood said.
Commissioner Travis Becker suggested rewriting bid instructions to take some of the unknowns out of it.
"I'll say between now and between Dec. 1, working with Dubbe-Moulder, (Fremont County Buildings Maintenance supervisor) J.R. (Oakley) and (deputy Fremont County attorney) Jodi (Darrough) and come up with a solution and talking with some of the contractors to ask what is the best way to do this," Becker said.
Commissioners voted unanimously to reject Wyoming Roofing & Supply's bid and to rebid the project after clarifying it following Becker's suggestions.
