Concrete In Australia : December 2013
16 Concrete in Australia Vol 39 No 4 NEWS Forensic engineering wrap The Concrete Institute of Australia’s September Seminar Series hosted delegates from around Australia who took the opportunity to avail themselves of over 80 years of accumulated concrete forensic expertise. Participants were able to mark up a full day of continuing professional development. Titled “Forensic Engineering in Concrete Structures”, the series was delivered in all mainland state capitals between 3 and 19 September. The Institute was fortunate to be able to make available the knowledge of three recognised presenters to a national audience: • Warwick Johnson, regional director, Brookfield Multiplex • Grahame Vile, director, BAAM Consulting • Peter Airey, managing director, Airey Taylor Consulting. The Concrete Institute of Australia extends its thanks to all who supported the 2013 November Seminar Series – presenters, day chairs and attendees.

Safety improvements for Paradise Dam The Queensland government has committed $10 million in additional interim repairs to Paradise Dam, southwest of Bundaberg. Owner SunWater advised the government that drain holes in the dissipator slab may contribute to a weakening of a layer of rolled compacted concrete within the dissipator, which protects the underlying rock. As part of Phase 3 investigations, SunWater conducted geotechnical drilling of the slab in October, and early findings suggested further strengthening of the slab was required, according to SunWater CEO Peter Boettcher. “These additional interim repairs include shielding dissipator drains, constructing a capping slab over the dissipator and installing additional monitoring equipment on the slab,” he said. Ongoing works to the dam are meant to address any concerns about damage to the slab that might be caused by extreme flood conditions, according to the state minister for energy and water supply Mark McArdle. However, the strengthening is not related to recent repair work, he said. The state had commissioned a review of the overall dam structure following extensive damage during floods in January this year. It commended SunWater for safety management actions, and ongoing remedial works aim to enable the dam to withstand multiple flood events like those seen last summer. 4-16 News.indd 16 4-16 News.indd 16 25/11/13 2:37 PM 25/11/13 2:37 PM
