Specification
PRACTICE & STANDARDSintermediate
Definition
A detailed written document accompanying construction drawings that describes the materials, products, workmanship standards, and installation methods required for a building project. The specification and drawings together form the contract documents from which contractors price and build the project.
Example
A specification clause for external brickwork might require a specific named brick, a particular mortar mix ratio, a defined joint profile, and a minimum weather exposure test result — ensuring the contractor delivers exactly what the architect designed.
