The freshly appointed NSW Building Commissioner has warned the state's construction industry that he will be watching their moves very closely.

Construction industry expert David Chandler, who was appointed to the role by Premier Gladys Berejiklian on Thursday, said the industry had "a culture of trying to avoid accountability".

"My single message would be for people in the industry who think you might go unobserved for the very near future, expect to see me in your site shed sometime soon," Mr Chandler said.

Ms Berejiklian said Mr Chandler's role would involve "driving critical reforms" in the construction industry.
