Staircase Layout And Section Details With Levels And Dimensions

This AutoCAD drawing provides a detailed staircase layout and sectional drawings prepared for architectural and construction coordination. The sheet includes ground floor and first floor stair plans at scale 1:20, showing clear tread numbering from 1 to 24, stair width of 1500 mm, and uniform riser and tread proportions of approximately 280 mm. Finished floor levels are clearly marked with Level 00 at FFL 0.000, intermediate landing at plus 2.10, and Level 01 at FFL plus 4.20, ensuring accurate vertical circulation planning. Balustrade references, structural stair cores, and alignment with floor slabs are clearly indicated to support precise execution.

The sectional views illustrate stair construction details, including landing connections, slab interfaces, and balustrade fixing zones. Dimensions such as stair rise repetition, landing depths, and structural offsets are annotated in millimeters, maintaining consistency with site requirements. Material references for stair components, guardrails, and finishes are clearly labeled, along with level markers and reference codes. Notes emphasize that drawings are not to be scaled and that all dimensions govern construction. This staircase detail drawing is suitable for architects, civil engineers, and builders requiring clear stair geometry, level coordination, and construction reference using AutoCAD documentation.
