Bridge Inspection & Maintenance Procedures

Bridges are valuable assets, which must be maintained and managed if they are to remain functional at optimal cost through their design life.


Defects do occur which require attention during the life of a bridge. Some bridge components have a design life less than that of the bridge and require periodic replacement.

Natural events such as floods and earthquakes cause damage. The bridge corrosion environment can affect durability and must be recognised. These areas must be addressed and appropriate maintenance carried out to ensure continued public safety as well as to maintain the asset and minimise repair costs.

Whilst this course does include a module on the inspection process, this is not considered in detail. Completion of this course does not certify delegates to inspect NZTA bridges. The NZIHT sister course Bridge and Other Significant Highway Structures Inspection is required.  

Who should attend

Engineers and inspectors with responsibility for inspecting and determining maintenance requirements for both state highway and local authority bridging. New and experienced bridge inspectors, engineers, technical staff and asset managers wishing to upgrade their knowledge should attend this course.

Participants to bring

This course is based on NZ Transport Agency’s Bridge Inspection and Maintenance Manual Revised Edition 2001, Code: SP/M/016

If you do not have a copy of this manual, it can be downloaded from the NZTA website

It is essential that representatives from each organisation attending have at least one copy of this manual to refer to at the course.
