Pickerington completed a major infrastructure improvement project Feb. 7, on state Route 256 while maintaining traffic at all times.
The city was able to do so because the repairs were performed underground.
The state Route 256 Storm Sewer Project repaired an existing storm sewer that was failing on the east side of 256.
It needed to be strengthened because the oval-shaped pipe became squashed, said Pickerington City Engineer Greg Bachman.
Contractor Layne Inliner LLC inserted a cured-in-place pipe (CIPP) into the failing pipe through existing manholes.
Bachman explained the process which kept Pickerington's busiest road free from substantial construction delays.
"The CIPP is essentially a long sock saturated with resin that is inflated and cured with hot water pumped into a sock," Bachman said.
"Once the CIPP is in place it is a structural liner that reinforces the failing pipe," he said.
The end result, Bachman said, is savings of both time and money.
"This 'no dig' option saves significant money over a normal dig and replace project," he said.
"It also keeps SR 256 open to traffic rather than closed during construction," Bachman said.
He told Pickerington City Council Feb. 5 the last section of pipe curing was going to be installed that evening.
The 2,400-foot long storm sewer is 15 feet deep and runs from Refugee Road to Postage Drive. It is 18 to 30 inches in diameter.
Bachman said the city's contract with Layne Inliner for the work was substantially completed on time.
The Hilliard-based company was paid $246,760 for the repair work, however, 74 percent of the construction costs were paid through a grant from the Ohio Public Works Commission, leaving Pickerington's share of the costs at $64,157.
Bachman credited outgoing Pickerington Construction Inspector Scott Parker with making sure the project was completed on time. The SR 256 Storm Sewer Project was Parker's last. He is retiring.
"Scott's done a great job in the four years that I have been (with Pickerington)," Bachman said.
