From 1 October 2011, all construction contracts will fall under amendments to the Construction Act. Key changes include: 1) oral contracts will now be covered; 2) adjudicators can amend clerical errors in decisions; 3) unenforceable "Tolent clauses" stipulating costs of adjudication; and 4) "pay when paid" clauses extended to "pay when certified". A new payment regime involves payment notices and default notices to establish payment amounts. The right to suspend work has also been widened along with recovering reasonable costs of suspension. All construction contracts should be reviewed for compliance with the new amendments.
