Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a contract modification for professional engineering services with AECOM Technical Services, Inc. for the Inflow Redirection - Markison, C.I.P. #650790-122181 and Hydraulic Modification to CSO Regulator - Markison, C.I.P. #650790-122182, in an amount up to $47,118.32. The modification work will be performed for the Wilson Avenue Area Water Line Improvements, C.I.P. #690236-100176.
This is an unplanned modification. The purpose of this modification is to construct necessary improvements to the water distribution system in the Wilson Avenue Area. The improvements identified in the scope of work will replace or rehabilitate water lines that have high break histories and require frequent maintenance. This project includes replacing or rehabilitating approximately 3,500 linear feet of 8-inch water lines. The streets include Oakwood Avenue and Linwood Avenue.
The original contract provided design services for the inflow redirection and hydraulic modification to the combined sewer overflow regulator on Markison Avenue. The water line work included in this modification was not part of the original scope. It was not until very late in design that it was realized it would be very beneficial to include water line replacement with the proposed sewer work. The final configuration of the utilities would make for a very difficult water line replacement in the future, and it made more sense to include the work now and with the sewer project.
This project is located within the following Community Planning Area: South Side (63).
