Home My WebLink About7/7/1999 - STAFF REPORTS (14) CO - DATE: July 7, 1999 TO: City Council FROM: City Engineer AMENDMENT NO. 1 TO SECOR INTERNATIONAL, INC. RECOMMENDATION: That the City Council approve Amendment No.1 to SECOR International, Inc., for an increase of $9,007.00 for the Underground Storage Tank Removals and Replacement - Corrective Action for Contamination, City Project 95-17. BACKGROUND: On March 17, 1999, City Council of the City of Palm Springs awarded SECOR International, Inc., the contract for the Underground Storage Tank Removals and Replacement - Corrective Action for Contamination project. The original work plan submitted by the City's consulting engineer, Tait & Associates and approved by the County of Riverside, Department of Environmental Health specified GeoProbe boring for 2 locations at the City Yard. The contractor, SECOR International, encountered contamination at increasing levels as the boring progressed. The GeoProbe did not reach the 40 ft. boring depths per the work plan. Because of the contamination found and the 40-foot maximum depth that the GeoProbe can reach, a HollowStemAuger must be used to continue the exploration to greater depths. Credit for boring depth not used and laboratory analysis (samples not taken) were given to the City ($1,091.00). Tait & Associates and SECOR International. recommended to the County of Riverside, Department of Environmental Health to use a Limited Access Rig (LAR) Hollow Stem Auger to continue to find the horizontal and vertical limits of the contamination. Tait submitted to the County, an amended work plan for approval. The amended work plan cost estimate by SECOR totals$5,149.00. The net increase to the amended work plan is$4,058.00 In Schedule A, the City requested and received from SECOR International a cost estimate of $4,949.00 for additional boring depths of 80 ft. (40 x 2) and soil analysis, in the event that contamination is found deeper than what the amended work plan calls for. The increase for this change order totals $9,007. Funds are available in account number 540-5904-48622 (Loss Containment) . Application for reimbursement from the State Dept. of Environmental Health has been made. The reimbursement is expected to cover the total amount. Yr' DAVID J. ARAKiAN f City Engine i -_ APPROVED: t l Manager b ATTACHMENTS: 1. Minute Order 2.
