Explanation

1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify an existing professional engineering agreement with Burgess & Niple, Inc. (Mod #2) for the Southerly Wastewater Treatment Plant Chemically Enhanced Primary Treatment - Disinfection, (SWWTP CEPT - Disinfection) Project. This project is one of three projects to provide Chemically Enhanced Primary Treatment (CEPT) at the Southerly Wastewater Treatment Plant (SWWTP), as approved by the Ohio Environmental Protection Agency. The CEPT facilities provide additional plant capacity to treat wet weather flows in excess of 330 Million Gallons Daily (MGD). This project will focus on upgrades and modifications to provide a new effluent conduit, disinfection chemical feed facilities, post aeration basin, and all associated structures and site work to accommodate these facilities.

This project will focus on upgrades and modifications to provide a new effluent conduit, chemical feed facilities, and levee modifications. This is a contract for professional engineering design services and services during construction (Design Professional, or “DP” services) for the SWWTP CEPT, Disinfection. Preliminary Design has been completed and Detailed Design is ongoing.

Engineering Services During Construction will be performed in two phases, in 2016 and 2017, when the proposed improvements are constructed. This current modification covers one aspect of these services, while it is anticipated a future contract modification will be requested for the remainder of this work. The 2016 phase is for Contract S86, CEPT Site Preparation and Improvements. The 2017 phase is for Contract S89, CEPT Disinfection.

The actual emplacement of the work will be by construction contract. This enginerring contract provides detailed design and bidding assistance, along with construction-phase engineering, start-up and commissioning assistance, and record documentation preparation. Construction Management services...
