Technical drawing under building technology refers to the precise and detailed graphical representation of buildings and construction elements. It is a fundamental tool used in architecture, engineering, and construction to communicate design, dimensions, materials, and construction methods clearly and accurately.
Key Features of Technical Drawing in Building Technology:
-
Accuracy and Scale: Drawings are made to scale, meaning every element is drawn in proportion to its actual size.
-
Standard Symbols and Conventions: It uses standardized symbols (e.g., for doors, windows, electrical outlets) to ensure clarity and universal understanding.
-
Types of Technical Drawings:
-
Architectural Drawings: Floor plans, elevations, sections, etc.
-
Structural Drawings: Show beams, columns, foundations, etc.
-
Electrical Drawings: Layout of wiring, switches, lights.
-
Plumbing Drawings: Water supply and drainage systems.
-
Mechanical Drawings: HVAC and other mechanical systems.

-
Purpose:
-
Guides construction professionals during building.
-
Communicates design intent from architect/engineer to contractor.
-
Ensures legal compliance and safety standards.
-
Assists in cost estimation and project planning.

Tools Used:
-
Traditionally: T-squares, compasses, drawing boards.
