Framing and joint details for wood corridor partitions intersecting wood floor-ceiling assemblies and post-tensioned concrete slabs. The partitions utilize wood framing with two-inch nominal lumber functioning as fireblocks at partition lines, faced with one layer of 5/8-inch Type X gypsum board to the underside of sheathing. Acoustical and fire sealants of 1/2-inch thickness are detailed at joints between gypsum underlayment and wallboards, alongside resilient sealants. Floor framing includes wood I-joists running lengthwise down the hall and suspended from structural beams beyond. Building services zones and floor-to-ceiling levels are clearly demarcated from the roof down to the concrete base.
