Analysis
The City's Water Master Plan calls for replacement of the 1 million gallon Robinson Road Elevated Water Storage Tank with a 2 million gallon tank to accommodate the growth of the city. The plan calls for the replacement of the tank and a 30"/36" water line to provide adequate supply to the tank.
The tank construction will need to be coordinated with the planned demolition and relocation of Fire Station No. 3. However, at the time the tank is constructed we need to have the 30"/36" supply line in place.
On February, 20, 2018 the City Council (18-7617) approved a professional engineering contract with Freese & Nichols, Inc. in the amount of $482,000, plus a 4% contingency of $17,000 for a total request of $500,000. The original contract provided for the 30"/36" water transmission line for Robinson Road elevated storage tank design, route feasibility studies including the detail of land acquisition for each route as well as the impacts on other utilities, streets, private property and related issues, minimizing impacts of the waters of the U.S., coordination with the Texas Historical Commission, perform surveys and easement descriptions, specify needed geotechnical work, detailed design of the water line, assist with bidding and evaluation of bids and selection of contractor, review of shop drawings, review of and administering change orders, final project review and production of record drawings incorporating deviations in construction from originals. Additional services were added for developing construction drawings and specifications for the relocation and removal of the existing 16" and 24" waterlines at the fire station property. It also included survey of the fire station property in the area of the existing waterlines and Level A & B subsurface investigation (SUE) in the amount of $48,912 was approved by City Council (18-7982).
On Tuesday, February 11, 2020, the City of Grand Prairie opened competitive sealed proposals (CSP) for the 30"/36" Robinson Road Waterline (W.O. #618.113) ). A total of seven (7) proposals were received for the competitive sealed proposal (CSP). The Director of Public Works, City Engineering, Inspector, and Field Operations met with Freese and Nichols, Inc. to evaluate each Contractor based on the Proposal Price and the Proposer's Key Personnel, Relevant Experience, and Project Methodology. Two Contractors, Atkins Brothers and Mountain Cascade of Texas, did not submit all the documentation required in the Bid Book and were therefore deemed non-responsive. Their total proposal score is based solely on their proposal price.
