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 became 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, these items were included in the first contract modification.
The first contract modification also increased 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. The first modification provided for additional engineering design for the master planning efforts.
The above referenced master planning efforts are complete; however the original contract work was suspended during the completion of the master planning work. This contract modification is to extend the contract completion date for the original scope of work, and to adjust wage rates for the years from 2006 to 2008. In addition the collector wells and vertical wells projects will now be bid and constructed as separate projects (5 separate construction contracts) in lieu of the originally anticipated 3 separate contracts. Engineering fees for Construction Administration / Construction Inspection are being adjusted accordingly with this contract modification.
CC 329.16 CONTRACT MODIFICATIONS:
1. Amount of additional funds to be expended under this modification: $153,130.00.
2. The extent of additional services provided are needed due to extending the contract completion date for the original scope of work, and to adjust wage rates for the years from 2006 to 2008. In addition the collector wells and vertical wells projects will now be bid and constructed as separate projects (5 separate construction contracts) in lieu of the originally anticipated 3 separate contracts.
3. The work under this contract modification is a continuation of work previously performed by the Consultant, therefore, no other processes were used for procurement of these services.
4. The cost of this modification is based on material and labor, and was negotiated between the Consultant and the City, as documented by the Consultant's quotation letters, and verified by the Project Engineer.
