Construction · Defined
Specifications
Written requirements describing materials, performance, execution, and other criteria for the work.
Why it matters
Specifications and drawings work together. A quantity-based budget can miss a required testing, warranty, or performance obligation that appears only in the written requirements.
In practice
A project example
The drawings show a roof assembly while the specifications define its testing and warranty obligations.
