The document provides details for constructing an atrium structure including a hollowcore precast slab supported by welded steel angles and brackets. It specifies a vapor barrier, cement particle board, mastic sealant, and floor finish. The atrium structure will support an extruded aluminum curtain walling system with flush joints sealed by silicone. The curtain walling is designed to have a water tightness of 600Pa or better and wind load resistance of 2200Pa or better. It will incorporate a drained cavity, rigid insulation, and double glazed units set in aluminum channels.
