12905B22R0007 Renovate Greenhouse-Buildings Amendment #4

USDA Physiology and Pathology of Tree Fruit Lab Wenatchee, WA

Questions/Answers

Q. A polycarbonate vendor cannot be fount who will warrant the design as is. Their feedback indicates the span is too large for the panels. Based on this information and the importance of the panels it is our concern any bid would be inadequate for the project needs. Similar feedback has been provided for the as related to the HVAC system, the specified system will not fit. With the current feedback it is our concern the greenhouse scope requires further exploration and design to properly estimate and delivery on a properly functioning greenhouse.

A.

Polycarbonate Roof System:

Existing system panel is approximately 8mm thick multi-wall that is 20.5 inches wide by over 16.5 feet long, and secured / supported by metal (aluminum) glazing bars / support rafters. As part of the structural system to remain, there are intermediate purlins running perpendicular to the structural mainframes and polycarbonate panels and metal glazing bars. These purlins are located at the ridge, eave and two intermediates that are equally spaced. The drawings and specification 13 34 13 indicate that the polycarbonate panels and all glazing bar systems are to be removed and replaced. The span of the system is not an issue based on the width and minimum thickness of a 12mm multi-wall panel, and the use of continuous length metal (aluminum) glazing bars / support rafters as described in the documents.

Mechanical System:

The mechanical system is being replaced within the same locations as they are currently installed. The water cooling wall and system fit in the same location as the existing system. Infrared heating system is smaller than the existing system installed with better control because it is split between the separated areas within the greenhouse. Exhaust ventilation increases at sidewall, but is not bigger than existing greenhouse sidewall and roof ventilation fits in the existing openings provided. We are unaware of what specifically will not fit as indicated in this RFI.
