Master Builders ACT have called on the Fair Work Commission to include the ACT branch of the Construction, Forestry and Maritime Employees Union in its application to place the troubled union into independent administration.
Ziad Zakout, Master Builders ACT acting chief executive, said it was disappointing and concerning the ACT branch of the union had not been included in the application.
"We know our local members have experienced the same illegal activity, bullying and downright thuggery that has been reported in other states on a daily basis," Mr Zakout said.
"The 2015 Heydon Royal Commission dedicated 337 pages to wrongdoing by the ACT CFMEU in their report ... without the ACT included, our members will be much less likely to come forward about their experiences and provide evidence, for fear of reprisals."
CFMEU ACT branch acting secretary Michael Hiscox offered a sharp rebuke of the Master Builders ACT.
"The Master Builders are relying on a decade old inquiry run by Dyson Heydon, a man found to have used his position of influence to sexually harass junior employees," Mr Hiscox said.
"This shows how desperate they are. As we have said before, we do not fear a criminal investigation into our industry. But it should look at the industry in its entirety, including members of the Master Builders and developers."
ACT Labor will not accept donations from any branch of CFMEU while an independent administrator is appointed to manage the embattled union.
Chief Minister Andrew Barr has repeatedly noted no allegations have been made in recent reporting in the Nine newspapers against the ACT branch of the union.
Delegates from the union attended ACT Labor's annual party conference last weekend.
A court application has been filed by the Fair Work Commission to appoint an independent administrator to the CFMEU's embattled general and construction divisions.
The commission in July revealed it would take action after accusations of criminal misconduct and bikie links were levelled at the union's construction arm in a series of reports published by the Nine newspapers.
On Friday, the commission's general manager Murray Furlong filed a Federal Court application to nominate an independent administrator to the CFMEU's general and construction divisions.
The commission has proposed the court appoint Mark Irving, a barrister with three decades' experience, to the position.
Labor's national executive has already severed ties with the CFMEU and will no longer accept political donations or affiliation fees from the troubled construction arm.
