Contractor requests explicit written confirmation that the Government’s response to this RFI is binding for the duration of the contract.

Yes, as per the documents listing in question 7 and other requirements per the SOW document, the Contractor is required to perform full designbuild engineering services (structural calculations, wind uplift, thermal performance, shop drawings, delegated design elements, code/DoD/AF compliance, etc.).
