JANUARY 19, 2010 SUBJECT: CONSIDER APPROVAL FOR THE PURCHASE OF EMERGENCY STANDBY GENERATORS AND TRANSFER SWITCHES FOR LIFT STATIONS AT VARIOUS CITY LOCATIONS RECOMMENDATION: City Council to consider approval for the purchase of emergency standby generators and switches from Facility Solutions Group for the lift stations at Dove #1, Hilton, Dove #2, Minters Chapel, and Hood Lane in the total amount of$384,722.66. FUNDING SOURCE: Funds are budgeted in account 325-48860-531-10-2010 Capital Equipment/Machinery Purchase Fund/Machinery and Equipment/Utility Wastewater. BACKGROUND: Bids were taken in accordance with Local Government Code Chapter 252, Subchapter B, Section 252.021 (a) and Section 252.041 (a). The bid was advertised in the Fort Worth Star Telegram on December 17, 2009 and December 24, 2009. This request is to approve the purchase of emergency standby generators and transfer switches for the lift stations at Dove #1, Hilton, Dove #2, Minters Chapel, and Hood Lane; The City sanitary sewer system has 31 lift stations that pump sanitary sewage from low elevations of the City toward the wastewater plant or to the TRA collection point.. Over the years, these lift stations have experienced several power outages. When there is a power outage, the lift station fills up and is in danger of overflowing, causing a sanitary sewer overflow. Overflows can result in fines and enforcement action by the Texas Commission on, Environmental Quality (TCEQ). As the City has grown, increased flow to the lift stations has reduced response times. In addition, Staff has little control over ONCOR from which power is restored. During the last major storm, the City came very close to having multiple overflows. The City's current method of keeping the lift stations operating during a power outage is to use two bypass pumps and a portable generator. These units are rotated between the stations until power is restored. Staff has identified the top locations that have critical flows and low detention times. The proposed purchase provides for generators at five of these critical lift stations (Dove, Dove 2, Hilton, Minters Chapel and Hood). The generators will be equipped with automatic transfer switches which will automatically turn on the generator when a power January 13,2010(12:53PM) outage is experienced. The City currently has a similar system at the Opryland lift station (the station that serves the Gaylord Hotel). Invitations to bid were issued to 11 qualified contractors with three contractors responding. A copy of the bid tabulation is attached for review. The bids requested pricing for the base bid cost of Dove #1, Hilton, Dove #2, Minters Chapel, and Hood Lane plus alternate costs for the lift stations at Kimball, Lakeview, Hilton (3-pump) and for adding sound enclosures for Kimball and Dove #2. Due to the pricing received and budgetary limitations, it is recommend that only the base bid be approved. Staff recommends approval to award a contract and purchase order to Facility Solutions Group for the purchase of emergency standby generators and transfer switches at Dove #1, Hilton, Dove #2, Minters Chapel, and Hood Lane in an amount not to exceed $384,722.66.
