Road Structures Inspection Manual

RSIM CoverBridges and other structures are key asset elements in the transport network. It is vital that their condition is monitored and essential repairs are planned and completed in an efficient and timely manner. Road Structures Inspection Manual (RSIM) defines that the condition of all structures is systematically monitored to ensure structural integrity and safety of road users and that there is sufficient data to effectively manage road structure assets.

The RSIM includes numerous road structures including retaining walls, noise walls, gantry structures and ferry ramps as well as bridges and culverts and replaces the Bridge Inspection Manual. It builds on statewide procedures for inspection and condition rating and includes changes to inspection scope and condition rating assessment, documentation and data management to reflect developments in both the department's current methods and national/international best practice.

The RSIM also incorporates the Bridge Repair Manual, which details standard repairs used in repairing defects in bridges and other structures.

Any questions or comments relating to RSIM should be addressed to DPTI.bmu@sa.gov.au.
