005 - Construction Specifications 101: The Project Manual Explained

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.
