Thompson, Public lVorks Director ATTACHMENTS: 1) 2) Change Order No. 1 Budget Change Form RECOMMENDATION: Approve additional appropriation in the mount of $9,081 Approve Contract Change Order No. I in the amount of $6,300. FINANCIAL STATEMENT: of bid award is as follows: The revised project budget approved by the City Council at the time Construction: Design/Inspection: Miscellaneous: $24,412 $ 2,500 $ 250 $27,162 Estimated project costs are: Construction: $28,493 Design/Inspection: $ 2,500 Miscellaneous: $ 250 $31,243 An appropriation in the amount of $4,081 is needed to process this contract change order. However, it appears some additional work may be necessary to repair aline that will not hold a pressure test, and Staff is recommending adding an additional $5,000 to cover potential costs. DESCRIPTION: The Civic Center Fuel Tank Upgrade project was awarded at the November 20, 2001, meeting. At the time of award, the City Council approved an appropriation for additional work that was required by the Alameda County Environmental Health Service, which is the regulatory agency for underground fuel tanks. Work on the project is now in progress, and two situations have arisen to cause the change order request. g:~rniscprojXfueltank\agstccol COPIES TO: Paradiso Mechanical ITEM NO. 1) Improvements related to pressure testing and provision of watertight fittings, $4,650. The testing procedure is a new Environmental Health requirement for 2002. Staff and the contractor recommended installation of the new watertight fittings to ensure passing the test procedure. Staff was aware of the new requirement and had planned to budget for additional work in the 2002-03 fiscal year; however, it is less costly in the long run to perform the work for the diesel tank now while the excavation is open. 2) Additional cost for concrete slab removal, $1,650. The standard thickness of a concrete slab for this type of fuel tank installation is 6" to 8". The slab at the diesel tank is 18" thick reinforced concrete. This condition was not noted on any existing plans or recOrd drawings. In the process of testing the existing fuel lines between the tank and the generator, the contractor has discovered that at least one of the lines will not hold a pressure test. It is now necessary to excavate to repair the leak in order to pass the Environmental Health inspection~ The exact cost of the work is not known at this time, but Staff is recommending that $5,000 be allotted to cover this work. Staff recommends that the City Council approve the additional appropriation of $9,081 and the change order in the amount of $6,300.
