CIP 751 – Culvert and Sewer Design –City of Columbus – Columbus, Ohio
This project was divided into two separate tasks, and separate construction plans were developed for each task. To alleviate street flooding along Olentangy River Road near Troon Trail in north Columbus, STONE designed a replacement culvert to provide increased capacity for runoff from residential areas. The project also included the development of construction drawings for an extension to the Olentangy Bikeway. The drawings were prepared using City of Columbus Drawer E format and included several street crossings, a pre-fabricated bridge, and solar powered warning signals. The other task focused on alleviating flooding at a railroad underpass on East Fifth Avenue east of Grant Avenue and west of Penny Street. This task included replacement and new inlets in the East Fifth Avenue underpass and designing a new storm sewer to replace an existing, undersized conveyance.
Intrusive subsurface investigations were performed for the Fifth Avenue storm sewer replacement to verify the location of existing underground utilities including water lines and fiber optic transmission lines. Maintenance of traffic plans, storm water pollution prevention plans, bidding assistance, attendance at the pre-construction meeting, reviewing shop drawings, and providing advice and direction on design issues during construction were included in the scope of these projects.
