Building Services Drafting Services

Precise CAD provides high-quality drafting services for building services engineering using Revit as our core platform. We produce intelligent 3D models and detailed 2D documentation for Mechanical, Electrical, Plumbing, Fire Protection, and specialist systems such as medical gases, communications, and security.
Our Revit-based drafting includes schematic layouts, single-line diagrams, installation drawings, builder’s work details, and coordinated plans for ductwork, pipework, cable trays, and equipment placement. Each drawing is generated from a data-rich model, ensuring spatial accuracy, clash-free coordination, and compliance with Australian standards.
We tailor our outputs for design development, prefabrication, construction, and as-built documentation — supporting efficient workflows and reducing site rework. Every drawing is backed by rigorous quality control and aligned with project-specific LOD and LOI requirements.
