Consultants <br />The City submitted a request for proposal to a consultant familiar with this type of <br />project and the estimated project administration cost submitted by the consultant <br />was $40,000. This cost includes specifying the proper generator and providing <br />specifications and contract administration for retrofitting City Hall for auxiliary <br />power. <br /> <br />Staff concluded that this option was too expensive and decided to work with <br />vendors independently to specify the proper generator for the City’s needs. <br /> <br />Sound Attenuation <br />Ziegler Cat, a vendor the City has been working with to develop generator <br />specifications, offers an enclosure for the generator that reduces the decibel level <br />considerably. As delivered the generator produces 71dB which is equivalent to <br />busy traffic or a noisy restaurant. As an option, Ziegler offers an upgraded <br />enclosure that reduces the decibel level to 55; 55dB is equivalent to light traffic, <br />refrigerator, or a light breeze. <br /> <br /> <br />Generator <br />Staff has contacted several vendors regarding the purchase of a stand alone <br />trailer-mounted generator. Originally three generators were budgeted. One was <br />to be a permanently mounted generator located at city hall. The second <br />generator would serve the well houses 5 and 6. The third would be smaller and <br />serve only the lift stations. <br /> <br />The budgetary break down for these items are as follows <br /> <br />City hall alternative power supply project $80,000 <br /> Trailer Mounted Generator (Wells 5 and 6) $70,000 <br /> Trailer mounted Lift station Generator $30,000 <br /> Total $180,000 <br /> <br />After extensive discussion Staff’s recommendation is to purchase two equally <br />sized generators that would serve all sites throughout the city capable of auxiliary <br />power. Staff feels this would provide much needed versatility in an emergency <br />situation. Furthermore, it would provide for the water department during peak <br />control periods to pump from multiple wells throughout the city. <br /> <br />Staff has solicited quotes from Ziegler Cat for budgetary purposes and those <br />numbers follow: <br /> <br /> Generator Price $70,000 <br />(Including Interconnect cables, 4 GFCI outlets, 4 exterior telescoping <br />lights) <br /> <br /> Sound Attenuation enclosure $44,705 <br /> (Enclosure reduces Decibel level from 71dB to 55dB)
