CPS and District staff prepared the plans and specifications for the project. The Engineer's estimate for construction of the Primary Structures Demolition Project, District Project 7255, is $1,400,000. This project was advertised on September 2 and 9, 2011. Six sealed bids, ranging from $929,000 to $1,443,600, were received and publicly opened on September 27, 2011. Engineering Department staff conducted a technical and commercial review of the bids and determined that Pantano Excavating, Inc. is the lowest responsive bidder, with a bid amount of $929,000. A summary of bids received is shown in Attachment 2. District staff will perform construction management, contract administration, inspection, survey, office engineering, and submittal review. CPS has performed satisfactorily during the design phase of this project and staff recommends retaining CPS to provide construction support services during construction of this project. The construction supports services include reviewing shop drawings and submittals, responding to design questions, evaluating change order requests, and performing site visits to verify compliance with the design intent. Staff has negotiated an amendment to the Professional Engineering Service Agreement with CPS in the amount of $30,000. This will bring the total contract cost for design and construction support services to $75,000. In addition to CPS, staff will retain a consultant specializing in asbestos and lead paint removal to assist in technical support/inspection. The funds required to complete this project, as shown in Attachment 3, are $1,325,000. The total cost of the Primary Structures Demolition Project, District Project 7255, is anticipated to be $1,480,000.

Staff has conducted a cash -flow analysis of the Treatment Plant Program budget and concluded that adequate funds are available for this project. Staff has concluded that this project is exempt from the California Environmental Quality Act (CEQA) under District CEQA Guidelines, Section 15301, since it involves minor alterations to an existing public facility involving negligible or no expansion of use.
