An investigation into the site was ordered after more than 100 workers downed tools and walked out two weeks ago because of concerns over the safety of a temporary stand being built at the Sydney International Aquatic Centre.
Their fears were confirmed this week with the release of an engineer's report which found the site was unsafe.
The report identified six separate areas of concern and recommended the immediate introduction of temporary bracing and other work to fix the problem.
Local Olympic officials said they remained confident the site would be finished on schedule for the Australian national championships in May.
The Aquatic Centre will be used to host swimming, diving, synchronised swimming and water polo events at the Olympics which start on September 15.
The centre was opened in 1994 but an extra 12,000 seats are being added to the venue to increase the capacity to 17,500.
