Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a contract modification for professional engineering services with Burgess and Niple, Inc. for the Mound Street Floodwall and WCLLP Repairs, CIP #611708-100000, in an amount up to $494,964.53.
The City of Columbus, Division of Sewerage and Drainage (DOSD), initiated CIP 611708-100000 to address the existing concrete floodwall located along the east side of the Scioto Trail, between Main Street and the Norfolk Southern/CSX railroad bridge, in the vicinity of the Miranova condominium tower. The wall has deteriorated significantly. Exposed reinforcing steel has created a safety risk, the crumbling concrete is an eyesore, and continued deterioration may lead to the failure of the floodwall. This Project will also address the spalling and cracked panels of the existing concrete wall sections along the West Columbus Local Protection Project (WCLPP), also known as the Franklinton Floodwall.
The initial phase of work for this Project involved reviewing historic data and completing field investigations associated with the existing concrete floodwall located along the east side of the Scioto River, between Main Street and the Norfolk Southern/CSX railroad bridge. Following the initial data review and field investigations, recommendations were prepared for the rehabilitation and/or repair of the Mound Street Floodwall and the damaged WCLPP panels.
This planned contract renewal will fund the design and development of plans for the rehabilitation and/or replacement of the existing Mound Street wall. It will also design and develop plans for effective and sustainable repairs to those panels of the WCLPP which exhibit significant spalling and cracking to prevent their failure.
The Community Area for this project is 37 - West Scioto, 54 - Franklinton, 55 - Downtown, 59 - Southwest, and 69 - Harmon Road Corridor.
