RECOMMENDATION: That the City Council approve Construction Change Order No. One to Tapuz Enterprises, Inc., for an increase of $13,656.88 for the Mid-Valley Parkway - Phase 1, Landscape Improvements Project, City Project No. 95-38. BACKGROUND: On April 7, 1999, City Council of the City of Palm Springs awarded Tapuz Enterprises, Inc. the contract for the Mid-Valley Parkway - Phase 1, Landscape Improvements Project. In reviewing the specifications for the proposed irrigation water main for the landscaping, Desert Water Agency (DWA) and the City's consulting engineer, RBF & Associates, agreed that the proposed 1 1/2 in. irrigation water main would not provide the necessary static water pressure for the irrigation system. This is due to the change from domestic to reclaimed water and information from DWA that the reclaimed water line has lower pressure than the domestic line. The irrigation water main will be modified as follows: Change 1 1/2 in. Sch 40 PVC mainline on the south side of Mesquite Avenue from Sta. 23 + 00 to Sta. 42 + 00 to 2 1/2 in. Sch 40 PVC, change 1 1/2 in. Sch 40 PVC mainline in the median from Sta. 42 + 00 to Sta. 72 + 00 to 2 1/2 in. Sch 40 PVC and change all 11/2 in. Sch 40 PVC mainline from the median to monument planter areas to 2 in. Sch 40 PVC. An adjustment of contract time (Contract Extension) will be made at a later dale between the City and the contractor, Tapuz Enterprises, Inc. An agreement as to price could not be reached with Tapuz Enterprises, Inc., on this item as they were asking in excess of$29,000.00. Staff proposes to proceed, therefore, on an Accumulation of Costs basis, in accordance with the Standard Specifications. The amount of this change order is based upon Staff estimates of time and material to complete the work. If additional time and material is required, an additional change order will be prepared.
