Relief Storm Sewer Design – City of Pataskala, Ohio
STONE prepared detailed construction plans for approximately 1,500 lineal feet of 12-inch and 15-inch relief storm sewer and 12 catch basins to alleviate flooding conditions on the west side of Summit Road. The existing storm sewer system was undersized and the City desired to convey peak flows via a relief storm sewer to the same receiving stream but through another area of the City. HydroCAD calculations determined that the relief route had sufficient capacity to handle the additional storm water flows, and detailed construction plans were prepared.
Major challenges to this project included limited conditions in which to construct the new storm sewers due to mature trees in one area, and the City’s plans to construct new sidewalks to serve the new schools in the area. Construction was scheduled so that the storm sewers were installed before the contractor mobilized to construct the new sidewalks. The new storm sewers were also constructed in close proximity to Summit Road, so that maintenance of traffic plans were also critical to the success of the project.
The project was designed, bid, and constructed within an 8 month time frame and required no major change orders. In addition to preparing the construction drawings, STONE reviewed contractor shop drawing submittals, prepared information and responded to contractor requests for information, visited the site to observe and document contractor progress, assisted with contract modifications, reviewed contractor pay requests, and prepared as-constructed plans in AutoCAD format.
