This drawing presents three detailed wall sections for a call center building, showcasing various facade treatments and construction assemblies. The primary section features a structural glazing curtain wall system with both clear glass (Type A) and spandrel glass (Type B) panels. Floor-to-floor height measures 4000mm between ground and first floors, with varying roof elevations (upper roof at EL 112.900). The facade integrates stone cladding with saveto painting on cement plaster, granite base elements, and steel handrails at stair locations. Notable technical aspects include the mullion detailing at mid-spans and ends, with careful attention to the junction between different cladding materials. The wall sections incorporate gypsum board interior finishes and address thermal performance through the spandrel panel design. The building includes ground floor commercial spaces (shop and hall entrance) with training rooms on upper levels; clear vertical circulation is provided through Stair 01. Material transitions are carefully detailed, particularly at the granite base-to-curtain wall interfaces.
