A quality control and inspection manual for hardwood stress-laminated and glulam timber bridges is presented. This manual is written primarily for bridge inspectors, fabricators, contractors, engineers, and owners. The two major objectives of this manual are: (1) to provide basic knowledge of wood and steel materials and stress-laminated and glulam bridge systems; (2) to provide specific guidelines for the inspection of bridge components before construction, inspection of construction procedures, and inspection of bridge systems in service. Toward this end, the manual is organized in two broad sections: (1) educational modules on wood, steel, and bridges systems; (2) inspection and quality control guidelines before, during, and after construction, which include checklists to guide the inspection of specific and important items during all phases of construction and service of a bridge.
