The majority of the 2‐story precast village buildings call out ladders at the roof hatches and a few like building #4 do not. Should we assume that we need a ladder at all roof hatches or are some meant as rappelling access only? See 1/99‐A‐702 for reference.

On page 73‐A‐201A and 89‐A‐202A, detail 1 there appears to be rectangular block outs on these details, what are these?
Some rendered village building elevations have rectangular block‐ outs. If it's not noted and there is no matching block‐out in the corresponding elevation please disregard the block‐out. Ex: 72‐A‐201 and 72‐A‐201A ‐ bldg. 72 back elevations ‐ both show same block‐out for window opening. However, 73‐A‐ 20 and 73‐A‐201A ‐ bldg. 73 front elevations ‐ block‐out shows on rendered elevation 73‐A‐20, so please disregard. LS3P

It is very confusing as there are openings #1, 2 or 3 “A, B or C” that are wood shutters, openings labeled #’s 1, 2 or 3 that are simply openings and then there are callouts for security grills that are not on these pages – example 89‐A‐101.

Per the drawings, the galvanneal panels in the shipping containers are shown as painted/finished, the galvanneal panels in the precast buildings are not shown as painted. What are the criteria for finishing these if any? A finish schedule will be helpful if differing finishes are required as they are not labeled throughout.

Are air barrier requirements required for the AAR trailer compound? The UFC 1‐201‐ 01, Non‐Permanent DOD Facilities in support of Military Operations, does not require it. Having to meet this specification for a building of this construction will be extremely cost prohibitive and is not industry standard. The manufacturers simply do not do this for these structures and will need to have a separate subcontractor come in and spray these walls before they are closed up. This will also require secondary air barrier work once the sections are being installed together onsite.
Air water barrier only recommendtion as long as UFC 1‐201‐01 non‐perm DOD facility offers an exception as stated in PPI question

Amendment #4, RFI responses 50‐58
In response to RFI #50‐58 responses, the original RFI is not referring to the G key tag. It is referring to the opening/door schedule to the number 7 in the hexagon that then refers you to the door schedule that is on sheet 99‐A‐401, that then gives you a letter which is G that then refers you to a detail on sheet 99‐A‐403 to door type G Lattice door. The floor plan drawings and elevation drawings conflict with each other. The elevation calls for an opening while the floor plan drawings call for DOOR NO 7 which when you go to the door schedule (sheet 99‐A‐401) you get all the door and frame information that then refers you to sheet 99‐A‐403 which stated that DOOR NO 7 is a type G Lattice door. Please advise what door number on the door schedule is to be used in each of these drawings where there is conflict.

In response to RFI 49 it states to use type C doors for all interior doors that are missing door information (the hexagon with a number in it that refers you to the door schedule on sheet 99‐A‐401 that then refers you to sheet 99‐A‐403 for the door type and detail, as well as the frame type and detail). From sheet 99‐A‐403 the door details type C doors are overhead coiling door, and there are also two different sizes for type C doors DOOR NO 4 and DOOR NO 5 on the door schedule on sheet 99‐A‐401. The floor plan drawings are showing swinging doors not any overhead coiling doors, additionally there is not the allowable space in any of the floor plans with the missing hexagon with a number in it that refers you to the door schedule on sheet 99‐A‐401 that then refers you to sheet 99‐A‐403 for the door type and detail, as well as the frame type and detail to put in either size of the type C door (overhead coiling door) that is in the door schedule. Please confirm the DOOR NO of the door that you are referring to on the door schedule.
assume all interior doors get door symbol #2 per door schedule on 99‐ A401. This references elevation “B” door per 99‐A403 and corresponding frame details 24, 25/99‐A402. No overhead coiling door. Swing

The floor plan drawing and elevation drawings conflict with each other. Please confirm the door number to be used in room 102 or if it is an opening because sheet 12‐A‐101 calls for DOOR NO 7 that when you go to sheet 99‐ A‐401 says DOOR NO 7 is door type G and on sheet 99‐A‐403 door type G is a Lattice door, but on the elevation drawing it shows it as an opening.
