Butler Area School District officials opened bids Friday for two major projects that will begin after the school year ends and be completed before classes resume in the fall.

Four bids were opened for a massive paving project in which the roads, parking lots, curbs and sidewalks at the senior and junior high schools and high school stadium will be resurfaced, and four bids were opened for replacing the roof of the Emily Brittain Elementary School.

The paving bids were $760,583 from Shields Asphalt Paving of Valencia, $818,000 from A. Folino Construction of Oakmont, $999,800 from Fulena Pavers of New Castle, and $1,462,119 from Wiest Asphalt Products and Paving of Butler.

The roof replacement bids were a $749,600 base bid and a $98,200 alternate bid from Triangle Roofing of Pittsburgh, a $833,000 base bid and a $93,000 alternate bid from Slippery Rock Roofing of New Castle, an $864,307 base bid and a $110,837 alternate bid from David Maines and Associates of Lewistown, and a $1.3 million base bid and a $100,000 alternate bid from Pennsylvania Roofing Systems of Bakerstown.

The bids will be reviewed by IKM, the Pittsburgh firm that designed both projects, to make sure they meet district specifications, said Nick Morelli, acting director of business services for the school district.

He said he hopes IKM will prepare a recommendation to accept a bid for each project for the school board in time for the next board meeting March 16.

“These are very good bids. They're in line with our budgeting,” Morelli said.

Eleven paving contractors and six roofing contractors attended a mandatory prebid conference to view the sites and review the specifications, he said. Only contractors that attended the meeting were allowed to submit bids.

The paving project specifications require work to start in the area of the stadium and require the contractor to work around the summer school schedule, and those factors might be among the reasons that only four of the 11 contractors who attended the prebid meeting submitted bids and could have affected the price of the bids, Morelli said.

He said the last time any paving work was done at junior-senior high school property was a partial paving project in 2006 or 2007. The speed bumps on Campus Lane were made during that project to protect an electrical conduit that was laid across the road, he added.

School roofs are replaced every 20 to 25 years and Emily Brittain's roof had some repair work done in 2002, Morelli said.

The alternate in the roof bids is for an extra layer of sheeting under the roofing material, said Jeffrey Foreman, senior project manager for IKM.

The school board will decide whether to add the alternate to the project, Morelli said.

The district will pay for the projects with money from a $9.7 million bond issue in 2017.

Dinsmore and Shohl LLP, the district's bond counsel, told the board in February that 85 percent of the $9.7 million in bond proceeds must be spent over three years, and the deadline is Dec. 20. Some already has been spent, but $7.3 million more must be spent by the deadline, he said.
