99 TRINITY ST

LIM tunnel 20x60 1200SF max occupancy 15 Yard Structures: LIM Tunnel (sw corner of yard) This is a 20x60 Soundproof ground-supported truss structure with double walls made of alternating layers of foam sheetrock plywood and wooden studs. Occupancy 30. Engineering drawings pending. Inside the truss structure participants will climb stairs and walk across a 16x60 steel deck platform through a physical projection-mapped display. The ground is uneven here so the decking will have an average height of 38 and slope from SW to NE with an overall elevation change of about 12. The deck itself and the truss structure will be level. Railings will be installed at all edges of the deck. Stairs will be used from an engineered steeldeck system. The ADA accessibility ramp in the drawings will not be placed. Future drawings will reflect this change. Instead a temporary lift will be installed near the eastern crash-doors exit from South Hall as indicated on the site plan.
