Answer: The roof is a standing seam system. Any non-penetrating seam clamp can be used if compliant with regional wind load requirements

5. Reference: Call 6 Statement of Work, Appendix 23 , Bid diliverables will include. Any proposal without documentation verifying FSEC certification (or written concerrence from FSEC documenting the proposad system's ability to be certified) will be rejected outright without further government review.

To obtain FSEC approval a design has to be submitted to FSEC, at this point a design does not exist. To bid this requirement we would incur costs that could not be recovered if we are not the successful bidder. Does this requirement need to be submitted with the proposal?

Answer: NASA assumes the system selected by the contractor for installation has previously been through the FSEC process. The government is not looking for a custom installation but seeking the best $/watt solution and a system with field proven performance. If a contractor feels a new previously unverified system would provide the best solution for NASA at the lowest $/watt installed - the contractor would be at risk. All proposals will be reviewed for technical acceptability - if the contractor can include documentation that ensures the government that the system proposed will meet the FSEC certification requirement pre-award - it will be considered.
