Abstract:

An update to 23 CFR part 650 Subpart C, National Bridge Inspection Standards (NBIS), was published on May 6, 2022. Section 650.315(f)(2) establishes the requirement for hands-on inspection of Nonredundant Steel Tension Members (NSTMs). State transportation departments, Federal Agencies, and Tribal governments (herein collectively referred to as “Agencies”) may choose to develop procedures in accordance with Section 650.313(f)(1)(i) of the NBIS to demonstrate that a member without load path redundancy has system or internal redundancy such that it is not considered an NSTM. This memorandum replaces and rescinds the June 20, 2012, memorandum “Clarification of Requirements for Fracture Critical Members.” Agencies with approved system redundant member procedures must update their procedures to satisfy the requirements of 23 CFR 650.313(f)(1) and submit for FHWA approval by June 6, 2024, pursuant to 23 CFR 650.311(g). The attached guidance outlines the process and criteria for Agencies to fulfill the requirements of 23 CFR 650.313(f)(1)(i) if they choose to implement procedures to identify members with system or internal redundancy.
