This architectural drawing depicts two comprehensive cross-sections (Section 01 and Section 02) of a two-story commercial call center building with an elevation reference system based on FGL=100.000m. This building features a modern curtain wall façade system with clear and spandrel glass panels supported by rectangular mullion profiles. Interior spaces include a ground floor with lobby, IT room, training area, and shop facilities, while the first floor (EL 104.000) houses call center operations, meeting rooms, and a cafeteria. Vertical circulation incorporates an elevator system and stairways with stainless steel handrails. The structure employs a combination of stone cladding and granite base for exterior finishing. Ceiling heights are standardized at 2700mm above finished floor level (FCL EL 102.700), with varying parapet heights: TOPR at 109.200, TOPR2 at 110.000, and TOPR3 at 111.600. The sections effectively illustrate the spatial relationships between functional areas while providing essential construction reference data for building envelope systems.
