The NSW Government has released an Independent Construction Industry Ratings Tool (iCIRT) which helps those seeking to purchase a home or apartment search for developers and builders who have a proven track record of quality and integrity, supported by objective evidence of their past cabaility. The more stars, the more confidence the public can have that the company is likely to deliver a reliable outcome.
