Home My WebLink About6 Hydro Excavator Purchase Agenda Item #i TRUCKEE DONNER Public Utility District 9 Memorandum To: Board of Directors From: Ed Taylor, Water Utility Manager Date: May 13, 2004 Date of Board Meeting: May 19, 2004 Subject: BID AWARD FOR PURCHASE OF A HYDRO EXCAVATOR 1. WHY THIS MATTER IS BEFORE THE BOARD Board approval is required for equipment purchases over $15,000. 2. HISTORY Excavating to repair the water system has become more problematic and expensive over the last five years. Cost of materials has increased, other utilities in close proximity, and regulations effecting the disposal of materials and trench water have all increased the cost of water system repairs. Staff has over the last three years been investigating different methods and equipment which could reduce the repair cost and simplifies the repair process. A common method among utilities used for digging is hydro-excavating. Hydro- excavating is the use of a vacuum unit and high pressure water to remove material. Other agencies in the area were contacted to determine their methods of excavating. Most of the other agencies either use Hydro Excavators or are in the process of acquiring one. The water department has a backhoe and two dump trucks scheduled for replacement in the next four years. Staff is working to incorporate any changes in methods to be in conjunction with future equipment replacement. Purchase of the Hydro Excavator would eliminate the need to replace the backhoe and possible one of the dump trucks. We have used TSD's unit to vacuum out leaks in the alley down town. In 2002 we leased a vacuum unit for a month to test how affective the Hydro-excavation method of digging was and the time and cost to repair leaks. This test was very i successful. The less time for repair, less material used, and compliance with < Lahonton regulations were all a very cost effect process. The size of the excavation is reduced by half. The time to excavate is reduced by 40%. The need for waddles and other erosion control materials is eliminated. The overall cost of a leak repair is reduced by 40%. In 2003 we leased one type of Hydro Excavator for a month, then later the another type for a month. All of the field crew members were involved in the evaluation of the Hydro Excavators. During the evaluation several important equipment features were identified as necessary for an effective Hydro-excavator to properly function for the District. Both manufacturers provide sewer cleaning equipment and Hydro Excavators. There is a major deference between these two types of equipment. The sewer cleaning units are designed to flush lines and pickup any loose debris. They are not design for continuous heavy dirt and rock excavation. The Hydro Excavator is designed for continuous heavy excavation. The direct drive blower, the suction tube design, and the extended boom rotation all are important features needed for the heavy use this unit will experience. Staff included in the 2004 Water Department Budget funding for a Hydro Excavator ($265,000). The Board approved financing form Municipal Service Group for the Hydro Excavator. 3. NEW INFORMATION Specifications were prepared and a request for bids was advertised for a Hydro Excavator. Bids were received and a bid opening was held on April 28, 2004. Four Bids were received and the results are on the attached Bid Opening Report. The apparent low bidder, Sierra Freightliner Inc. of Reno Nevada ($247,194.50) does not meet all of the bid specifications. Elements in Sierra Freightliner's bid that did not meet specifications included a belt driven blow, a suction tube design (this is very problematic), and a limited boom rotation. The unit that they are bidding is a sewer cleaner modified for Hydro-excavating. Staff leased a similar unit in 2003 and found that the suction tube design had problems with plugging when digging in rocky material. The other three bid meet all elements of the bid specifications. The second low bidder Super Products Company of Milwaukee, Wisconsin with a bid of $260,747.27 has bid a unit that meets all of the specifications for the Hydro Excavator. 4. RECOMMENDATION Recommend that the Board reject the bid submited by Sierra Freightliner Inc. of Reno Nevada in the amount of $247,194.50 as non-responsive, and additionally recommend that the Board award the purchase of a Hydro Excavator to Super Products Company of Milwaukee, Wisconsin in the amount of $260,747,27.
