Introduction
Specifications are an integral part of construction documentation and provide detailed instructions that complement plans and blueprints. These instructions stipulate the type of materials, construction techniques, dimensions, colors, and other specifics required to complete a project to the desired standards.
Examples
Here are a few examples illustrating what specifications might encompass:
- Material Requirements:
- The building specifications state that number 3 lumber shall be used for all framing.
- Layout Details:
- Studs are to be on 16-inch centers for consistent spacing.
- Color Directives:
- All exterior surfaces shall be painted white.
