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.
