Content
1. Working Drawings vs. Construction Drawings
- Working Drawings: These are technical drawings used by construction teams to understand how to build a project. They include details on dimensions, materials, and construction methods.
- Construction Drawings: A general term that includes all types of drawings used to build a structure, including working drawings, structural drawings, electrical drawings, etc.
2. Types of Working Drawings
- Elevation Plans: Show the exterior views of the building, including height and design features.
- Section Plans: Detail the interior features of a building, such as wall structures, floor plans, and vertical relationships between spaces.
- Foundation Plans: Illustrate how the foundation of a building is designed to support the structure, including dimensions and materials used.
- Ground Floor Plans: Show the layout of the ground level of the building, including rooms, walls, doors, and windows.
3. Functions of Grid Lines on a Site Plan
- Grid Lines: Serve as reference points for accurately positioning elements on a site plan. They help ensure that elements like walls and foundations are aligned and placed correctly in relation to each other.
4. Types of Plans
- Site Plan: Shows the overall layout of the site, including the building’s placement, access roads, and any surrounding structures or landscape features.
- Block Plan: A simple representation of a building’s footprint, indicating its shape and location on the plot.
- Foundation Plan: A detailed drawing of the foundation of the building, specifying materials and dimensions.
- Ground Floor Plan: A detailed layout of the first level of the building, showing rooms, doors, windows, and other key features.
