Overview
This module introduces construction drawings, explaining their purpose, basic components, and types commonly used on job sites.
Purpose of Construction Drawings
- Construction drawings are graphic representations showing how buildings or structures will be built.
- Drawings communicate design, layout, and dimensions to all members of a construction team.
- Used as a reference during all phases of construction for accuracy and coordination.
Types of Construction Drawings
- Plans show layouts from a top view, such as floor plans or site plans.
- Elevations illustrate the vertical surfaces or sides of a structure.
- Sections and details provide cutaway views and show specific construction features.
- Schedules list information about materials or finishes for components like doors and windows.
Components and Reading Construction Drawings
- Title blocks identify the project name, drawing number, date, and responsible parties.
- Scale indicates the proportional relationship between the drawing and the actual structure.
- Symbols and abbreviations are used for common building elements and materials.
- Legends explain the meaning of symbols, abbreviations, and line types.
