Explanation

BACKGROUND: The original contract for the South Wellfield Expansion provided for engineering design and construction administration services for the expansion of the well fields serving the Parsons Avenue Water Plant. The original contract scope was based on the recommendations of the Water Beyond 2000 project which was a planning document. Upon initiating detailed design it has become necessary to increase the project scope and fee for additional services associated with test drilling, additional monitoring well installations and miscellaneous design changes to the collector well structures.

In addition, the Division of Water has determined that it is appropriate to increase the project scope and fee to undertake water supply / master planning efforts associated with the sand and gravel operations currently underway along the west side of US 23 and south of Interstate Route 270. The City of Columbus currently owns and operates four collector wells in Southern Franklin County, which provide the source of supply of the Parsons Avenue Water Plant (PAWP). The gravel/quarry operator (Olen) is planning to extend its operation further south and also is planning to quarry the limestone that exists below the sand and gravel. This mining operation will be completed in phases in the vicinity of the existing collector wells. Due to these additional mining activities, it is essential for the City to evaluate the potential impacts on water supplies to the PAWP and develop both short-term and long-range plans to address related impacts. This modification provides for additional engineering design for the master planning efforts.
