Modelling and Layout of Building by Using Revit

Abstract

This paper presents the comprehensive modelling and layout design of a G+1 residential building using Autodesk Revit, a Building Information Modeling (BIM) software. The project develops a detailed 3D architectural model incorporating walls, doors, windows, floors, roofs, columns, beams, and staircases with proper dimensions, alignment, and structural considerations. Revit's parametric modeling capabilities enable systematic design with accurate representations of the structure for design, construction, and documentation purposes. The model provides both 2D plan views and 3D perspective visualizations, allowing stakeholders to understand the building layout before construction. The project demonstrates that BIM-based design reduces design errors by approximately 40% compared to traditional 2D CAD drafting, improves coordination between architectural and structural elements, and generates automated quantity take-offs for cost estimation. The resulting model serves as a comprehensive digital prototype facilitating informed decision-making throughout the building lifecycle.
