Explanation
BACKGROUND: The existing intake bar screens at the Dublin Road Water Plant Raw Water Intake have been in continuous service since 1951 and require replacement. As a part of programming services and investigation, Malcolm Pirnie Inc. (MPI) will also make recommendations of new technology that would facilitate spontaneous leaf removal and establish a debris barrier, to greatly reduce the accumulation of leaves prior to entering the intake bar screens. MPI provides all office and field services necessary to prepare technical reports and design documents for construction bidding, and provides technical and administrative services and field project representation during construction to execute the bar screen replacement and installation of associated appurtenances while simultaneously maintaining an adequate flow of raw water into the treatment plant. This contract modification will provide for engineering design for rehabilitation of the Low-Head Dam and associated permitting and construction administration and construction inspection services. The original contract provided for evaluation services for the existing low-head dam to determine the condition of the existing dam, but did not provide for detailed design for rehabilitation of the dam. After completion of the dam evaluation it was determined to be in the best interest of the City to move forward with rehabilitation of the dam immediately due to deficiencies identified during the evaluation. The low-head dam is needed to impound water for the raw-water intake which provides water supply to the Dublin Road Water Plant. Failure of the dam would limit the supply of water to the plant directly affecting the amount of treated water the plant could produce. The construction administration/construction inspection services were identified in the original legislation to be performed under a modification to the original MPI contract.
CC 329.16 CONTRACT MODIFICATIONS:
1. Amount of additional funds to be expended under this modification: $436,982.00
2. The construction administration and construction inspection services identified to be included in this contract modification were identified in the original contract however costs for these services were not identified at that time. It was not possible to accurately estimate the costs to perform these tasks until the first phase of the work was completed. The original authorizing legislation (#0527-2005) indicated the expenditure for construction administration services would be authorized by a future modification when the scope of services could be better defined. In addition this modification will provide for detailed design for rehabilitation of the low-head dam, and associated permitting for the construction work on the low-head dam. The original contract provided for engineering evaluation services for the existing low-head dam to determine the condition of the existing dam, upon completion of the evaluation it was determined to be in the best interest of the City to perform design services for rehabilitation of the low-head dam with this contract, this contract modification will provide funding for these design services.
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.
CONTRACT AMOUNT:
Original contract amount $564,182.00
