HomeMy WebLinkAboutAgenda Report - February 3, 1993� OR CITY OF LODI COUNCIL COMMUNICATION AGENDA TITLE: Contract Change Order - Well 3-R Drilling, 144 South Rose Street (Southwest Corner of Hutchins Street Square) MEETING DATE: February 3, 1993 PREPARED BY: Public Works Director RECOMMENDED ACTION: This item is for information only. No action is required. BACKGROUND INFORMATION: This information is being given to the City Council in accordance with the Contract Change Order policy approved by Resolution 85-72. One of the requirements of this policy is that we inform the City Council of all change orders over 10% of the contract amount. The attached contract change order, approved by the City Manager, was in the amount of $11,190, which is 16.40* of the contract. Under normal circumstances, the development of a well consists of dropping a portable pump into the well to remove the mud and sand. Occasionally, this procedure is not effective and there are times when the well will become clogged during the drilling operation. When a well becomes clogged, as did Well 3-R, specialized procedures such as chemical treatments and selective strata pumping must be attempted. Both were tried and the strata pumping was successful. This change order covers the work needed to do the selective strata pumping. Fifteen working days were added to this contract.
