Explanation
1. BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the professional engineering services agreement with URS Corporation - Ohio for the South Wellfield Expansion - Collector Well 106 and Pump House Project, for the Division of Water Contract No. 1000.
This current modification (No. 4) is for additional design and engineering services due to required regulatory documentation that was not foreseen at the time of the last modification. The Ohio EPA (OEPA) is requiring an aquifer safe yield analysis that involves extensive modeling efforts in order to identify an approved capacity of the Parsons Avenue Water Plant (PAWP) wellfield for submittal to the OEPA. This became known to the department and engineering firm in the summer of 2013 however negotiations were still be conducted into the early fall.
1.1 Amount of additional funds to be expended: $33,536.00
Original Contract Amount: $ 1,210,000.00 (EA025198-002)
Modification No. 1 $ 422,592.00 (EL004639)
Modification No. 2 $ 153,130.00 (EL006781)
Modification No. 3 $ 238,349.00 (EL012573)
Modification No. 4 $ 33,536.00
Total (Orig. + Mods 1 - 4) $ 2,057,607.00
1.2. Reasons additional goods/services could not be foreseen:
The OEPA recently changed their interpretation of their regulatory documentation that explains how to calculate the approved capacity of a wellfield aquifer, and requested a more extensive analysis be performed than what has been performed in the past. One of the major features of the new analysis is that capacities are measured by the well pumps not the well itself which is a new methodology.
1.3. Reason other procurement processes are not used:
The current consultant is familiar with the project and has completed all the work to date on the plans as well as has been the main point of contact for all involved regulatory agencies. Bidding the work to another consultant will further delay the project and will probably ...
