McCluskey, Public Works DirecWQoy' Prepared By: Wayne Peterson, City Engin \ me SUBJECT: Storm Drain Improvement Projects: El Cerrito / Flora Easement, Specification No. 96-OSE and California - Hathway to Stafford, Specification No. 96-OSC. CAO RECOMMENDATION Approve contract with Madonna Construction in the amount of$95,400 for Specification No. 96-05E and authorize the Mayor to execute the contract. Reject bids received for Specification No. 96-OSC and direct staff to re-evaluate the project. DISCUSSION In February 1996, the City Council added $200,000 to the Capital Improvement Program for flood improvements. Staff identified and Council approved certain priority projects. All but two of the projects approved by the Council are either completed or are under construction. The two projects remaining are the subject of this staff report. Council on October 1, 1996 authorized the staff to advertise Specification No. 96-05E. This project repairs the storm drain in the El Cerrito/Flora Easement. The low bid for this project was received from Madonna Construction Company in the amount of $95,400. The engineers estimate was $82,000. The CAO on August 20, 1996 authorized the staff to advertise Specification No. 96-05C. The project has now been advertised twice. The first time it was advertised no bids were received. The project was advertised a second time with Specification No. 96-05E because Staff hoped,that since the two projects are similar, more bidders would be interested and present bids for both. The low bid for this projects was received from RMR Inc. in the amount of $57,290 The engineers estimate was $40,000. Both of these projects were designed by a consulting engineering firm. They also prepared the estimate. The kind of work involved, lining existing pipes, is a specialty item and not often done in this area. This is the probable reason for the bids being above the engineers estimate. Since the total of the two bids exceeds the fund balance staff has evaluated the two projects and recommends the project in the El Cerrito/Flora Easement be prioritized over the one in California Blvd. The California project should be restudied and possibly redesigned to lower its cost and allow portions of it to be constructed with any funds remaining after this and the other projects already under construction are completed. The basis for the prioritization of the El Cerrito/Flora project over the California project is the extensive deterioration of the existing pipe, the difficulty in accessing the pipe and the potential for damage to private property should the pipe fail. FISCAL EMPACT On February 27, 1996 Council authorized $200,000 to be budgeted for Storm Drain Improvements. Approximately $80,000 has been obligated for other projects, leaving $120,000 to support this project. Award of Specification No. 96-05E. $ 95,400 Contingency Fund 10,000 Total Encumbrance $105,400 Estimated remaining Fund Balance $ 14,600 ALTERNATIVES 1. The Council could choose to fund both projects by appropriating an additional $47,000 from the General Fund. Staff does not support this option because it is felt that redesign of the California project can lower its cost. However, even with the redesign, the project will most likely cost more than the $14,600 fund balance and additional City Council action will be necessary. 2. The Council could also choose to award the contract for the El Cerrito/Flora project as recommended and direct staff to drop the California project. Staff continues to recommend the California project as a needed project. If it is deleted now it will appear again on other lists of deficient storm drainage systems.
