Q1. Will there be a site visit for this project?

A1. Yes, there is now a scheduled site visit on Tuesday, May 16, 2016 at 10:30 a.m. Located at:

National Institute of Standards and Technology Fort Collins Radio Station 5701 N. Hwy 1, Fort Collins, CO 80504 See “Site Visit Information” for important details at the end of this Amendment.

Q2. Is the proposal due on August 16, 2016 at 8:00 p.m.?

A2. No, it is now due on August 19 at 10 a.m. MT

A6. No.

Q7. Are there specifications on the new generator and transfer switch in addition to the posted specs?

A7. No.

Q8. Are we replacing equipment with like kind? If so, is there information on the existing transfer switch and generator?

A8. The equipment is being replaced is:

Caterpillar Generator Model D343 Series A, Engine Serial No. 62B845, 6 Cylinder, 5.4 Bore, and 6.5 Stroke.

Caterpillar Transfer Switch – no model or serial number. Switch is 36”deep, 45” wide, and 90” tall and weighs approximately 700 pounds.

Q9. Will permitting be required? If so, what type(s)?

Q12. Is there a control wiring diagram? What is it's function?

A12. The control wiring supports basic functionality of the generator and transfer switch. Examples are to start and stop the generator, monitor critical failures such as over-crank, high temperatures and loss of oil pressure. It is common practice that the manufacture of the equipment would provide a wiring diagram or blueprint that indicates how to wire the generator to the switch gear so that the two pieces of equipment would operate with each other.

Q13. What size/type is the new electrical cable and control wiring?

A13. The contractor shall determine the size /type based on the manufacturers recommendations and applicable NEC codes.
