Construction specifications are the written instructions that tell contractors how to build what the drawings show. They define the exact materials, products, and installation methods required for every element of a construction project.

In this episode, registered architect Emily Hobbs shares a real jobsite story where a missing railing almost became a serious dispute, until the specifications proved it was clearly defined in writing. She breaks down how specs and drawings work together, the CSI three-part format (General, Products, Execution), and why well-written specs protect everyone on the project.
