FOR SOUTHSIDE II (S2-6) 48-INCH WATER TRANSMISSION MAIN FROM BOLT STREET AND ST. LOUIS AVENUE TO THE EXISTING 42-INCH WATER LINE LOCATED NEAR THE INTERSECTION OF GRANBURY ROAD AND TRAIL LAKE DRNE RECOMMENDATION: It is recommended that the City Council authorize the City Manager to execute Amendment No. 2 to City Secretary Contract No. 25308 for engineering services with Halff Associates, Inc. for additional work related to the Southside II (S2-6) water transmission main for a fee of $81,530, increasing the total contract amount to $417,130. DISCUSSION: On May 25, 1999 (M&C C-17438), the City Council authorized the execution of an engineering agreement with Halff Associates, Inc. for the preparation of plans and specifications for the Southside II (S2-6) 48-inch water transmission main for a total fee not to exceed $320,720. The Southside II (S2-6) water transmission main project is part of the Water and Wastewater System Master Plans-Water System Plan prepared in 1989. Under this recommendation, a 48-inch water line is proposed from the existing 48-inch pipeline crossing of IH-35W at Bolt Street (Mapsco 91 F) to the existing 42-inch water line located in the vicinity of the intersection of Granbury Road and Trail Lake Drive (Mapsco 89M). The purpose of this project is to provide increased flow capacity to allow full utilization of the Rolling Hills Water Treatment Plant. Recent high summer demands and growth in southeast Fort Worth have reinforced the need for this water main. This contract was previously revised by Amendment No. 1 on October 2, 2000, and City Secretary Contract No. 26224, for a fee of $14,880, increasing the total contract amount to $335,600. In December 2000, the City requested the engineer to revise the plans and specifications to include all existing streets to be pulverized and surfaced with full width asphalt pavement and new curb and gutter, where required. The original design did not include new curb and gutter. Amendment No. 2 will include additional services to provide plans and specifications for rehabilitating all streets within the limits of this project, additional survey, and revising contract documents and drawings. The staff has reviewed the proposal from Halff Associates, Inc. and considers the fee in the amount of $81,530 to be reasonable for the additional work to be performed. Halff Associates, Inc. is in compliance with the City's M/WBE Ordinance by committing to an additional 30% M/WBE participation on this amendment No. 2. The City's goal on this amendment No. 2 is 28%.
