DISCUSSION: On June 18, 2002 (M&C C-19124), the City Council authorized the City Manager to execute an engineering agreement with Freese and Nichols, Inc. in the amount of $925,449 to prepare plans and specifications for Holly/Northside II 54-inch Water Main Extension, Contract I. The project was divided into three units in order to expedite construction. Units 1 and 2 are currently under construction. Unit 3, Section "A" was advertised for bid in August 2004. Unit 3, Section "B" will be advertised in December 2004. This contract was previously revised by Amendment No. 1 for $58,500.00 on August 12, 2003 (M&C C- 19698) and Amendment No. 2 for $ 82,554.15 on January 20, 2004 (M&C C-19938). These amendments provided for additional services, which included limited construction inspection and preparation of plans for additional water and sanitary sewer lines. The anticipated cost of Unit 3 exceeds the initial estimates due to alignment modifications necessitated by the Trinity Vision Project. Amendment No. 3 will allow Freese and Nichols, Inc. to separate the Unit 3 project into two separate contracts (Unit 3, Section "A" and Unit 3, Section "B"). The total cost to complete Section "A"will be approximately $5 million. The total cost to complete Section "B" will be approximately $4 million. The contract will be separated to give more opportunities to bidders. The Water Department anticipates the northern half ( Unit 3, Section "A") to be completed by next summer. The southern half( Unit 3, Section "B") is currently being designed. The additional work to be performed in Amendment No. 3 consists of the following:- - Re-route of two sections of 54-inch pipeline due to the proposed Trinity Vision Improvements located south of Jacksboro Highway;- - Design of a new connection point to tie the two construction contracts;. - Preparation of additional temporary and permanent construction easements;. -Additional survey and geotechnical analysis of the new water line new alignment;- - Preparation of storm water pollution prevention plans for the additional construction contract; and- -Additional efforts in reviewing shop drawings, construction phase services and reproduction costs. Freese and Nichols, Inc. proposes to provide the additional engineering services for a lump sum fee of $182,336.00. City staff considers this fee to be fair and reasonable for the scope of services proposed.
