Explanation

1. BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the professional engineering services agreement with DLZ Ohio, Inc. for the South Wellfield Expansion - Raw Water Line Project, for the Division of Power and Water.

This current modification is to perform geotechnical services to determine pipe bedding requirements, any potential groundwater issues, and to evaluate corrosivity and the potential need for corrosion protection in the event steel pipe is installed. This additional geotechnical work will require additional survey work to locate the soil borings. Additional coordination activities are required with ODOT due to new requirements and coordination with upcoming interchange improvements in project area. The original contract was anticipated to be completed in 2004, at time of Modification No. 1 the project was anticipated to be completed in 2007. The current schedule anticipates the project to be bid for construction in 2012. Wage rate escalation and additional coordination meetings required due to project schedule delays.

1.1 Amount of additional funds to be expended: $150,838.93
Original Contract Amount: $460,284.00
Modification 1 $295,499.94
Modification 2 (current) $150,838.93
Total (Orig. + Mods 1 - 2) $906,622.87

1.2. Reasons additional goods/services could not be foreseen:
At the time of the original contract and the first contract modification City specifications did not allow for utilization of steel pipe as an approved material for large diameter water line installation. It was also the philosophy at that time that soil boring investigation was not required for water line installations. City specifications will soon allow for steel pipe to be bid as an equal product to PCCP, requiring geotechnical investigation for corrosivity and possible corrosion protection design. ODOT has introduced new requirements for environmental reports to be completed when a utili...
