Taking the BIRM Mobile
When engineers inspect bridges, they rely on a 2,000-page manual for guidance. The Bridge Inspector’s Reference Manual (FHWA NHI 12-049) (BIRM) typically is contained in two three-ring binders and explains just about everything a bridge inspector needs to know about implementation of the national bridge inspection standards, the duties of a bridge inspection team, basic bridge terminology, and how to perform inspections.
