Bridge Inspection, Rating and Structural audit

Bridge Inspection Rating

Bridge inspection rating refers to the assessment of the condition and structural integrity of a bridge.

It involves a comprehensive examination of various components of the bridge, including the superstructure, substructure, and foundation, to evaluate its safety and performance.

  • Bridge inspection – thorough examination of the bridge’s structure and components 
  • Bridge rating – assessing a bridge’s capacity to carry loads safely
  • Structural audit – detailed assessment of the bridge’s structural integrity

Structural Audit

A structural audit, also known as a structural assessment or evaluation, is a detailed examination of the load-bearing elements and structural integrity of a building or infrastructure asset. A structural audit specifically focuses on assessing the condition and stability of the bridge’s components, including beams, columns, piers, abutments, and foundations.

Purpose of a structural audit

  • To identify structural deficiencies
  • To identify defects
  • To identify potential risks
