The Brisbane CBD building site is questioned on the safety issues when one of his workers was crushed by a concrete beam yesterday.

After this accident around 300 fellow workers have ceased their work and refuse to restore their work until the site is proved to be safe by builders of Laing O'Rourke.

In order to bring back the workers on site, a meeting was held between subcontractors and union representatives at the site only to converse on the safety issues at the tower.

Most of the workers are worried for the matter that there was no exit route available for them in case of any mis-happening, said by builders Labourers Federation city organiser Kane Pearson.

Mr Pearson told brisbanetimes. com. au yesterday that we don't want to put anybody on risk and for that we want to settle all safety related problems.

This accident took place on bay one which is easily accessible but workers are most concerned that if any accident took place up on higher floors then rescue become difficult and workers demands that all the safety improvements should be completed before they join work at the site.

Mr. Pearson also said that the site is 18 months old and since then only there were so many issues related to safety problems between the unions and builders of Laing O'Rourke.

A statement said that Laing O'Rourke has witnessed many incidents where they have rescued the people from the accident site and claims that safety of workers is the top priority for the company. Although Union does not comment on this statement.

It is expected that construction of the tower will be completed in December.
