Q: Sectin 2.2.G.2.a.e indicates the ceiling assembly t have type C bard but there is n specificatin fr type C bard. This is nt a huge issue I just want t make sure that everyne is bidding type C bard at the ceilings. If type X bard wuld nt affect the STC test, very much we may be able t save a bit frm the type C. A: As nted abve, Type C gypsum bard is nt a requirement fr the ceiling assembly in apartments, and the spec is updated. In an effrt t save csts, eliminate sectin 2.4.D per attached updated specificatin. Q: Sectin 2.3.B. calls fr a minimum f 33 mil studs fr all walls and sffits. I wuld cnsider this verkill fr the majrity f flrs were the deck height is less than 0 save walls bearing tile r cabinetry. Based n allwable limiting heights by the manufacturer I d nt see why 9 mil studs wuld nt be sufficient fr mst walls, which wuld prvide a significant savings. My cmpetitrs may be taking this assumptin in their base bid, s I just want t make sure we are all bidding the same either way. Thughts? A: Attached specificatin has been amended t allw alternate thickness as lng as they meet ASTM C 645 requirements.
