- Description
- RECOVERY THIS ANNOUNCEMENT IS TO INCLUDE ADDITIONAL INFORMATION REGARDING THE ROOF AND MOUNTING BRACKETS FOR THE SOLAR PANELS PER QUESTIONS SENT IN. ALL OTHER ASPECTS OF THE SOLICITATION REMAIN THE SAME, INCLUDING THE CLOSING DATE OF DECEMBER 17, 2009, 4:30 PM MOUNTAIN TIME. QUESTIONCan you give me a description of the roof detail for the mounting hardware that will be needed for the solar collectors? Also will you require any fasteners to attach the brackets to the roof and if so what are the specifications? Is there a requirement for roof penetrating fasteners? As of now the RFQ only requires the panels and no mounting hardware. RESPONSEOur roof is a 4:12 pitch Wick Building metal roof. The attic is accessible through the rafters from inside the building. The trusses are 8' on center and the purlins are 2' on center. We will need all mounting hardware and fasteners and they must be rated to hold the maximum weight of the panels when full including 90 mph wind load. The mounting kit will need to be a 45 degree mounting kit for each panel (six total). QUESTION No mounting frame kits were specified, is this an omission ? Flexible hoses are available for interconnecting the collectors but, were not specified, omission? Item N calls for a Caleffi z-one actuator in the text but, the characteristics also include a valve body, is it a complete valve (actuator and body), there are also several types of Z-one, which is required? Item O, the Caleffi # 644350A in the specs does not seem to be correct, please advise. RESPONSESee response above for mounting frame kites. Flexible hoses are fine. We will need the complete valve with actuator and body. The specific specs (Salient Characteristics) were listed for the z-one actuator and must be followed. The actuator does not have to be a Caleffi but must be compatible with the system package. The number 644350A is for the diverter valve (O) not the actuator (N). The specs are correct. I did go to the site and typed in the number. If they have more questions they may want to contact Caleffi.
