Case Study: Boral Timber Ltd achieves millimetre-level paving accuracy and improved terminal safety with Trimble 3D Paving Control System

Precise 3D Paving boosts safety at transportation terminal

Boral was contracted to pave the NSW Ports’ Intermodal Logistics Centre at Enfield, a major intermodal terminal in south‑west Sydney handling about 300,000 TEU per year. The site required extremely uniform, well‑drained asphalt across 92,000 m² to protect 90‑ton wheeled cranes and prevent ponding, with a target final surface average conformance of 0 mm and a standard deviation of just 4 mm—tolerances beyond what traditional paving methods could reliably deliver.

Boral, with SITECH support, used Trimble’s 3D Paving PCS900 workflow (Business Center‑HCE designs, SPS930 total stations, MT900 prism and CB460 control) to upload uncompacted 3D models directly to the paver, eliminate staking, and keep surveyors off the ground. The system enabled rapid design uploads, greater flexibility, less material waste and reduced crew exposure, and achieved the project target—an average standard deviation of 4 mm across the full 92,000 m²—delivering measurable safety, productivity and cost benefits.
