Australian of the Year and Diversity Council Australia chair David Morrison is to act as a "high level mentor" to Geocon managing director Nick Georgalis in the wake of Friday's construction site nudity scandal in Canberra.
The company has already apologised for bringing topless and scantily clad women onto its Wayfarer Apartments site in Belconnen as part of a "topping out" event.
A Geocon spokeswoman, who spoke with Mr Morrison on Saturday, said the former chief of army had agreed to mentor Mr Georgalis and recommended Geocon join the DCA.
"Geocon has already taken steps to do this," the spokeswoman said.
Senior Geocon staff are to meet with the ACT Minister for Women, Yvette Berry, later this week to discuss ways of effecting cultural change.
"Geocon welcomes the approach adopted by Yvette Berry which has been very much along the lines of 'how can I help you?' The purpose of the meeting is to discuss positive ways of moving forward," the spokeswoman said.
Friday's "topping out" event was held to mark the completion of the highest point on the 88-metre tall, 27 storey, 235 apartment Wayfarer project.
Work on the iconic building, billed as the city's tallest residential tower, has been underway since 2014.
Mr Georgalis said on Saturday he regretted that what should have been a happy occasion had been overshadowed by the use of inappropriate entertainment.
"It is a tradition in the construction industry for workers to mark the "topping out" of a building," he said. "I need to re-evaluate what is acceptable."
There had been no safety issues. The company said the only people present, apart from the entertainers, had previously been inducted onto the site.
Geocon is one of the largest players in the Canberra apartment market.
It has reportedly bought more than $50 million worth of land in the ACT since the start of the year.
The most recent acquisition, for $25.02 million, was NRMA House on Northbourne Avenue in July.
Steps are already underway to distance current and future projects from any fall out from the inappropriate workplace culture scandal.
"Geocon has initiated a whole raft of things to drive cultural change within the organisation. A project plan, which will set out a timeline and the steps that need to be taken, is now being prepared. This will lead to transformational change over time - we don't expect to have all the answers right away," the spokeswoman said.
"Geocon is engaging a cultural change consultant and will be working with the best people in the field. The company will be acting on their advice."
No individuals are known to have been disciplined over the use of the entertainers to date.
"There is a genuine concern [within the company] to get this right. It is not about apportioning blame [to individuals] but changing the culture so this type of thing, which was once considered acceptable on building sites, does not happen again," the spokeswoman said.
