Technical Note TN 067: 2014

Issued date 13 August 2014 Effective date 13 August 2014

Subject: Revised requirements for examination of crib walls and examination frequencies for steel and concrete underbridges in TMC 110 Structures Service Schedules

This technical note is issued by the Asset Standards Authority as an update to RailCorp

standard TMC 110 Structures Service Schedules, Version 3.1.

This technical note has been developed using the content from RailCorp technical note

CTN 13/11 and ASA technical note TN 001: 2013, and includes information relating to revised

requirements for detailed examination of structures for crib walls and examination frequencies

for steel underbridges and concrete underbridges. This technical note replaces CTN 13/11 and

TN 001: 2013 in full.

Other standards that are similarly affected include the following:

ESC 302 Defect Limits

TMC 301 Structures Examination

1. Background to revised requirements for thedetailed examination of structures – crib walls

In June 2013, a retaining wall at Harris Park collapsed. The investigation that followed included

a review of existing engineering standards related to retaining structures. The review identified

gaps in the documentation and recommended that relevant engineering standards be amended.

TN 067: 2014


2. Background to revised examination frequencies for steel underbridges and concrete underbridges

As part of the 2013 RailCorp Technical Maintenance Plan (TMP) review project, the

examination frequencies for steel underbridges and concrete underbridges have been

amended.

The new requirements are based on the age of the bridge under consideration.

3. Summary of updates

Updates to TMC 301 provided in this technical note are as follows:

Service Schedule 202 (SSC 202) – Mid-Cycle Examination of Underbridges. This

schedule is to be re-titled ‘General examination of underbridges’.

Service Schedule 223 (SSC 223) – Detailed examination of retaining walls and platform

walls

Service Schedule 231 (SSC 231) – Special examination of structures

The reference section of the all service schedules are to be amended so that reference

is made to ‘TMC 301 Structures examination manual’ only. Reference to ‘Volumes’ of

TMC 301 is to be deleted.
