Northern Construction is nearing completion of the $19.3-million Willimansett Bridge Rehabilitation ahead of schedule despite the challenges of a hard winter and taking over after Canton, Mass., contractor Pihl Inc. went broke.
The 125-year-old, 800-ft x 50-ft bridge carries Massachusetts Route 116 over the Connecticut River and Pioneer Valley Railroad between Holyoke and Chicopee in western Massachusetts.
"MassDOT [Massachusetts Dept. of Transportation] was helpful," says Shawn Clark, project manager for Northern Construction, Palmer, Mass. "But this has been challenging with a tight schedule."
The bid-build contract has a $3000-per-day incentive, capped at $90,000, to finish before July 11 with a late penalty of $6,222 per day until the bridge opens, Clark says. After November 7, liquidated damages will take effect at $1,500 per day until all work is completed. The original $18-million contract had a final completion date of May 13, 2014, according to MassDOT.
Since Northern Construction took over last May at 35% completion, it has had to work two 10-hour shifts daily. Work has included repairing or replacing sway bracing, lower lateral bracing, gussets and other steel members on trusses; replacing existing rivets with new high-strength bolts and cover plates; and bolstering all the numerous existing connection plates, Clark says.
"The existing deck is off the bridge, so we had to engineer temporary steel-plate decking so we could utilize a small crane to access repairs in the middle of the bridge," Clark says. In winter, painting required tent enclosures with heat maintained above 50° F and ongoing snow removal, he says.
The project completion cost to MassDOT did not increase due to Pihl's Chapter 7 bankruptcy, filed in September 2013, MassDOT says, since the contractor's bonding company paid $6.4 million.
