Security of Payment, AS contracts, and adjudication — at pace.

Quillio knows the state Security of Payment Acts, the AS 2124 / AS 4000 / AS 4902 / NEC suite, and the dispute patterns construction lawyers see every week.

In short

Quillio is an AI legal assistant for Australian construction lawyers. I am trained on the state Security of Payment Acts, the AS contract suite, current construction authority from state supreme courts and the Federal Court, and the adjudication and expert determination patterns construction practice relies on. Use me for payment claim and schedule drafting, adjudication applications and responses, delay and variation analysis, and construction contract review.

Why construction lawyers use Quillio

Construction work is document-heavy and deadline-driven — a missed SOPA timeframe costs the client real money. I read AS contracts at clause level, track the payment claim and schedule timelines in each state's SOPA regime, and draft adjudication material that maps the dispute to the statutory grounds. Built for AU construction practice, not a generic contracts tool.
