Why this matter is before the board: Approval from the Board of Directors is necessary to issue a Change Order to a constrcution contract. 2. History: The Board previously awarded the Installation of Services for the North Shore of Donner Lake—Contract A project to Hard Line Excavating (HLE). At the Board of Directors meeting on September 1, 2004, the Board approved Change Order No. 1 for this project in an amount of $4,719.25. This Change Order all of the outstanding issues encountered from the start of the project to August 5, 2004. 3. New information: DENTON AVENUE TO ROBIN LANE: The overall plan for rehabilitation of the Donner Lake Water System calls for the installation of a 12-inch pipeline along a portion of Robin Lane to connect to existing 12-inch pipelines that were installed under previous contracts. The location of this pipeline is given in Figure 1. This portion of Robin Lane is a "paper" roadway in that it was delineated in the subdivision map, but there is not actually a driven road along this alignment. There is an overhead pole line along this alignment that carries electric, telephone and cable TV facilities. The total length of the pipeline is just under 500 feet and Ed Taylor had originally intended to perform this work with Water Department personnel. There were some concerns regarding potentially sensitive areas along this alignment and it was felt that a District crew could be more patient and spend more time addressing any environmental sensitivities. In the early Summer of 2004, a contractor hired by the Electric Department cleared the brush and removed some trees along this alignment as the part of the ongoing safety efforts. Once the tree removal was performed, the exact water pipeline alignment could be determined with certainty. The Water Department then had Inland Ecosystems revisit the pipeline alignment to verify any environmental sensitivity. One small ditch crossing was found that required speciai Page 1 attention. Scott Ferguson of the Lahontan RWQCB also visited the site to review the proposed pipeline alignment. Y Therefore, due to the reduced potential for impacts to sensitive areas and the current workload f on the Water Department, it was determined a contractor should perform this work. Hard Line Excavating is performing work directly adjacent to this project area and I requested a price quotation for the work. Their price proposal is: Item Quantit Unit Price Total 44 12-inch water pipe installed 500 feet $89(foot $ , 00.00 $1,6 Single Service, Non-Traffic 1 $1,600 $100.00 s 1.5-inch Water Service Lateral 202 et $$,400t $2,800.00 Connections to Existin Pi in $49,500.00 Total 's REED AVENUE EXTENSION: staff has identified the need for a pipeline extension. There is a second location where District This location is on Reed Avenue just west of 14888 Donner Pass Road and is shown in Figure of 12 inch pipeline as part of the 2. In 2003, Hail's Excavating constructed about 150 feet driveway extension associated with a private residence at 14888 Donner Pass Road. At that time, District staff anticipated that this pipeline would be extended about 900 feet all the way to West Reed Avenue. However, this line extension was canceled due to the wetland areas farther to the west. There are five existing residences that are served by a small 1-inch pipe that runs downhill from the Greenpoint Springs property. It was originally planned to connect these houses to the new pipeline connecting to West Reed Avenue as it was built. When the 900-foot line extension to West Reed Avenue was canceled, a shorter line extension should have been included in the Installation of Services for the North Shore of Donner Lake - Contract A project to serve the existing houses. However, this pipe but was inadvertently omitted from the Contract Documents. 1 requested a price quotation from Hard Line Excavating for this work, which should have been part of their original Bid. Their price proposal is: Item Quanti Unit Price Total 4-inch water pipe installed 180 feet $65/foot $11,700.00 Single Service, Non-Traffic 3 $1,600 $4,800.00 3 /f co1.5-inch Water Service Lateral 602 et $�o400t $2,800.00 Connections to Existing Piping 10- $325.0- AC Pavin $21,425.00 Total 4. Recommendation: I recommend that the Board authorize Contract Change Order #2, in the amount of a $70,925 payment to Hard Line Excavating from the District. The exact payment to Hard Line Excavating will be adjusted if installed quantities differ from those used for the price estimate Attachments: Change Order Form, Figure 1 & Figure 2 Page 2 L NI ° Change Order i INSTALLATION OF SERVICES FOR THE NORTH SHORE OF 'l Contract Name: DONNER LAKE —CONTRACT A Contract Change Order No: 2 Orig.
