We request that IN ANG confirm this response based on mission and operational needs.

17. (FP/LS) Per Section 1.7.2.1 can the designer that is Nicet IV, take on all responsibilities that are listed for QFPE?

Engineer (QFPE) to perform fire alarm design services. However, it is important to note that this section reference, 28 31 76 §1.7.2.1, does not exempt the contractor from the obligation of engaging a QFPE to fulfill the remaining services as specified in the contract documents and UFC 3‐600‐01.

In addition, the Contractor must provide Monaco Manufacturer’s Technical Representative for 1 day of on‐site [technical training] per Section 28 31 76 §3.11.2.1. We request that IN ANG confirm this response based on mission and operational needs.

20. (FP/LS) Do we need to provide a Firefighter Phone?

76 §2.24, is not necessary for this project. We request that IN ANG confirm this response based on mission and operational needs. Firefighter phone is not necessary.

21. (FP/LS) Do we need to account for 5 Days of technical training at the Manufacturing Facility?

ANSWER: In our opinion, 5 Days of technical training at the Manufacturing Facility, as required per Section 28 31 76 §3.11.2.1, may be unnecessary. We request that IN ANG to provide further clarification on whether the duration requirement for technical training can be reduced or eliminated. We do not require technical training.
