1.The suggested heater CO RAY VA " shall be a U-Tube Design with opposite 45° reflector, mounted at 10' AFF " will generate damaging temperatures. Please confirm both the install height and model intended for use.

This is a follow-up answer to question 1 on Amendment 0005

Answer: Based on the buildings heating requirements (see Basis of Design and Specification), I would be uncomfortable with reducing the heat capacity further. The heating capacity of the existing greenhouse is 280,000 btu/h. After the renovation, the greenhouse will have a heating capacity of 250,000 so the heating capacity will slightly be reduced and will be better located to provide heating at the plants. The current design has single stage heaters. I propose that we have the contractor provide heaters with modulating control capability so that USDA personnel can adjust the heat as they need. By going to a modulating heat system, it may require going up to the next BTU unit, so instead of a 125,000 single stage heater, it may be a 130,000 modulated heater. As for the reflectors, the specification calls for stainless, but the drawing schedule indicates galvanized. I suggest the contractor provide the stainless reflector and if we need to VE something, we can discuss alternate reflectors.
