This webinar invites two experienced Structural Designers, John Woodside and Andrew Derbidge to review the detailing of reinforcement in concrete

Concrete reinforcement for designers:  Tips, tricks, and traps and how to get it right the first time and save your client money. John Woodside
John Woodside is concerned that there are many engineers that do not get adequate on-site experience to feedback on their design. They are so obsessed with the computer program and the model they do not realise the analysis is only half the design process. The other half of the design is putting adequate information onto a drawing that represents what they have analysed, and which is buildable on site. They do not understand reinforcement and how it is produced and fail to read or understand the detailing clauses in AS 3600. They often overdesign, sometimes under design, their detailing is poor, and they lack an understanding of practicalities on site. He thinks many of them do not understand the risks when concrete structures are not appropriately detailed.

Concrete reinforcement for designers:  Tips, tricks, and traps. Andrew Derbidge
With an increasing amount of concrete’s engineering, analysis, and design being done by “black box” software, there’s a concern being increasingly voiced in the industry that today’s structural design engineers are losing touch with some of the fundamentals of reinforcement detailing – not to mention the difficulties encountered on site.  There is often a disconnect between the engineer’s assumptions and expectations; the drawings produced for the builder; and the final detail that meets the engineer when s/he gets to site to sign off on the reinforcement.  This presentation looks at some of the tips and tricks available in AS3600 that many engineers overlook; some detailing solutions that can save your client money (and produce more sustainable outcomes); and also looks at some of the traps that need to be avoided.

The webinar will run from 2.00pm to approximately 3.00pm (AEST) and delegates will be emailed login details and a password for this webinar 24 hours prior to the event.

John Woodside is a consulting structural engineer in Adelaide with over 50 years of experience as a designer of a wide range of concrete buildings and, in recent years, prefabricated concrete, including projects for the Sydney Opera House. He was on the original committee for AS 3600 for over 10 years as well as chairing a previous version of  AS 1170.4  and the ceiling standard AS 2785. He has won the John Connell Gold Medal and is an honorary member of the Concrete Institute of Australia. He has presented many papers at CIA conferences over the years and was part of the winning team for the Kevin Cavanagh Trophy in 2017 in the CIA biennial Awards for Excellence in Concrete with the Cadogan Song School in Perth.

Andrew Derbidge is a consulting structural engineer in Sydney with over 25 years’ experience as a designer.  A director of Partridge, he specialises in high-end, architecturally-designed, residential homes and typically works on houses with construction budgets between $5M and $20M.  His designs and projects have won many engineering awards, including the Concrete Institute of Australia’s National Medallion for Excellence in Concrete in both 2017 and 2019.
