WTR WELL 04-16-84 . ~ ~§?E~ELOPMENT AGENCY ~TE: APRIL 10, 1984 ~~/ mmmter-¢om FROM: $ UBJ ECT: WILLIAM HUSTON, EXECUTIVE DIRECTOR TUSTIN COMMUNITY REDEVELOPMENT AGENCY BOB LEDENDECKER, DIRECTOR OF PUBLIC WORKS/CITY ENGINEER AUTHORIZATION TO ADVERTISE FOR BIDS - COLUMBUS-TUSTIN WATER WELL PROJECT RECOMMENDATION: That the Tustin Community Redevelopment Agency, at their meeting of April 16, 1984, adopt the attached Resolution approving plans and specifications for the Columbus-Tustin Well Project and direct the Secretary to advertise for bids. BACKGROUND: The Columbus-Tustin Water Well Project is proposed to be constructed in two phases. Phase I includes the drilling of a 1600 ft. test hole, associated soil testing and water sampling, the drilling/reaming of the final production well and the placement of the well casing and screens. Phase II will consist of the installation of the wellhead facilities consisting of the pump, motors, valving, sand extractor, and the equipment enclosure structure. This bid package will cover the work within Phase I of the project. The location of this proposed water well is at the southeasterly corner of Prospect Avenue and Beneta Way on the future Columbus-Tustin Parksite. The pumping equipment will be housed in a structure that will be architecturally compatible with the surrounding area. The Redevelopment Agency has currently budgeted an amount of $350,000.00 in the 1983/84 Town Center Redevelopment Agency budget. DISCUSSION: In Phase I, all proposed drilling operations will be performed on a continuous round the clock time 'schedule until the desired depths have been attained. The Contractor will be required to furnish, install, and maintain adequate noise control equipment during the drilling operation. It is estimated that the test hole operation will take approximately three weeks to complete and the production well construction will take about six weeks for completion. The Phase II design of well head facilities will commence as soon as the test hole has been completed and the results of the various testing is available. AUTHORIZATION TO ADVERTISE FOR BIDS - COLUMBUS-TUSTIN WATER WELL PROJECT APRIL 10, 1984 PAGE 2 The estimated cost for Phase I is as follows: Base Bid Schedule ! ................................. .......... $272,000.00 Bid Schedule A ................................................. 327,300.00 Bid Schedule B ................................................ 275,100.00 Bid Schedule C ................................................ 308,100.00 The variable amounts of each schedule listed above provides for a different type of well screen material. The type to be selected will depend upon the degree of corrosiveness of the soils/water which will be determined by a testing during the various steps of the test hole project. A preliminary cost estimate for Phase II is $150,000.00. This amount will be dependent upon the findings of Phase I and will hopefully be a lower amount. A tentative schedule for Phase I and Phase II is as follows: PHASE I Agency Authorization to Advertise for Bids for Test Hole and Production Well ...................................
