Request for Information and NPS Responses dated June 15, 2023

1. The bid schedule was revised with amendment 7, removing the sistering framing and the façade at 8&10. Are these items to be removed from the project or to be included in the base bid? If removed from the project, is the bracing of the façade to be included in the base bid?

a. Sistering framing and the façade at 8 & 10 are bid options 7 and 8 respectively and are not to be included in the base bid.

2. Spec section 01 81 13, 1.2 A refers to FSC wood used to make products. This
