The membrane roof was replaced in 2013 with TPO roofing, and has a ten year warranty till March 22, 2023.

Reference Drawing AE100: The following note on the drawings referenced seems to indicate that only those walls marked by a “dashed” line are to extend to the underside of the roof deck (scaled to be 24’ A.F.F.). This would mean all other partitions which do not have a “dashed line” extend up to the 8” framed platform above the ACT as shown on drawing AE300. Is this a correct interpretation of the required partition heights?

Follow wall type details shown on drawing AE100. Question stated is correct for type B6 walls, requiring 5/8" GWB on each side of framed studs, to underside of the roof deck. See detail on drawing AE111 for area of platform, B6 wall stops at bottom of the platform. Type A3 wall also extends to underside of roof deck with GWB on one side (behind showers, toilets, and lavatories). Type D3, D4, and D6 walls vary.

Type "D" walls shown with "Dashed" line along the Corridor extend to the underside of the roof deck with GWB on one side extending to the underside of the roof deck, and GWB on the other side only going 6" above the acoustic ceiling. With type "D" walls that are not dashed, will have GWB on each side of framed studs at 16" oc, to 6" above the acoustic ceiling, stud framing for these walls will continue above the acoustic ceiling to the upper roof deck at 32" oc, per wall detail notes for bracing.
