The plain-English guide to NSW traffic plans
In-depth answers on Traffic Control Plans, Traffic Guidance Schemes and Construction Traffic Management Plans for NSW builders, developers and contractors. Written by Markus K, PWZ-qualified traffic plan designer.
Staring at a Notice of Determination wondering what "CTMP", "TCP" or "TGS" actually means for your build? Quoted a number that sounds wrong? Builder telling you Council won't accept the plan? This is where we explain it.
Every guide answers a specific question NSW builders ask us — no consultant jargon, real cost ranges, and the exact DA condition wording most councils use. The library is being built out across five clusters: council-by-council guides, document comparisons, cost and timing, compliance and regulations, and project-type explainers.

Yes — almost always. Council conditions a CTMP on 8 in 10 duplex DAs across the LGA. Here's exactly when it's triggered, what it costs ($1,500–$3,000), and the rare edge cases where a cheaper TCP is enough.
