1) Is a transformer required for the power service to reduce down from 3‐phase? If power is to come out of the 3‐phase MDP, then a transformer will be required to step down service to the 125A panel.

‐No, remove existing 120/208v 3 pole breaker and provide new 120/208v 2 pole breaker

2) What is the occupancy classifications to determine if a fire alarm system is required?

‐Zero occupancy

3) Who is responsible for the stump that is to be removed from the site if government is removing the slab?

‐17 CES will remove

4) Is the contractor allowed to use the RV space during construction for housing of employees?

‐Yes, however only 3 max RV spots will be available @ $500 per month/per space.

Any depth shallower than 3’‐0” would most likely require a foundation with piers.

‐Yes, base design on 3' ground water depth

6) Are offers available to be sent via email?

‐Yes. Email is preferred. If the offer exceeds 5mb, they will need to be submitted via AMRDEC (https://safe.amrdec.army.mil/safe/) due to email transfer size restrictions.
