Hospital water tank analysis called into question

ENGINEERING models used to determine the fault point of a collapsed hospital water tank have been called in to question amid claims construction began before design plans were provided.

The hearing into engineer Jason Lindsay and Lindsay Consulting wrapped up yesterday with Magistrate Rod Madsen expected to make his ruling on Friday.

They were charged with failure to comply with a health and safety duty that exposes a person to risk of death, serious injury or illness after a Sunshine Coast University Hospital water tank collapsed in 2015.

The offence carries a maximum fine of $1.5 million for a corporation, or $300,000 for an individual.

Mr Lindsay's barrister John Bremhorst told the court during his summary the analysis conducted by Dr Nicholas Stevens and Professor Peter Dux into the fault couldn't be relied upon.

The pair were approached by Workplace Health and Safety Queensland to examine the cause of the collapse.

Mr Bremhorst said the constructed tank - which was analysed - was different to Mr Lindsay's design and had been half-built by another company before it received the certified design.

During Dr Stevens' evidence in December last year, he said the tank would have collapsed sooner if built to Mr Lindsay's design.

Mr Bremhorst further argued his client had no obligation to inspect the tank after it had been built and was not told when it had been finished.

The failed thermal energy storage tank caused about 2.7 million litres of water to engulf Kawana Way during the hospital's construction.

Currimundi mother-of-two Lou O'Brien and her twins Zali and Alex were almost swept away, but managed to free themselves from the car before it was washed into a wooded area.
