The sign at the front gate of a building site does a lot of work. It tells inspectors, neighbours, deliveries and emergency services who's running the job and how to contact them, and in most states some of that information is required by law. This guide explains what usually goes on a site board, state by state, and which of our site signs suit each.
Site sign requirements come from WHS laws and state building and planning laws, and your development consent or building permit may add more. This guide is general information. Check your approval conditions and your certifier or building surveyor before ordering.
The national baseline: principal contractor details
Under the model WHS Regulations adopted in most states, the principal contractor on a construction project must make sure signs showing their name, contact phone numbers (including after hours) and the site office location are installed and clearly visible from outside the site. Our principal contractor site sign is laid out for exactly this.
