Design and Construction Guidelines for the Delivery of Large Cantilever and Gantry Structures

Over recent years there have been a number of incidents of structural failures of sign and high mast lighting structures across Australia and New Zealand, primarily due to poor design and construction practices. In addition to the obvious unacceptable safety risks and property damage caused by such incidents, these failures create substantial unforeseen operational costs to repair and modify these assets. This often results in significant traffic delays and imparts reputational damage to the governing road authority and other parties involved.

The Austroads report Design and Construction Guidelines for the Delivery of Large Cantilever and Gantry Structures documents consistent advice for the design and construction of large cantilever and gantry structures that is aligned with national and international best practice.

This webinar, presented by Claire Jager, Linda Ziebell and Andrew Wong, covers the following key topics:

• gaps in current guidance and standards
• examples of good practice
• lessons learned from past failures.

The guidance document should be read alongside relevant standards and is intended for use by all stakeholders including:

• state road agencies
• local government agencies
• designers, contractors and fabricators.
