The drafting services under this roof

The drafting services we run in-house cover the documentation spectrum most projects need from one supplier: mechanical part and assembly drawings to AS/NZS 1100, structural steel detailing to AS 4100, electrical schematics and building services layouts, architectural DA and construction documentation, and 2D drawing production from sketches, markups or legacy files. Because every discipline sits in one drawing office under engineering review, multi-discipline packages stay coordinated — the structural penetrations match the mechanical services, and the electrical containment fits the ceiling zone — without the consultant-to-consultant email chains that usually erode that coordination.

What to send for a fixed-fee quote

Quoting needs less than most clients expect: whatever design material exists — hand sketches, photographs, consultant drawings, a physical part or a verbal brief on a call — plus the deadline and the format your downstream users need. Every quote is fixed-fee and returned within 24 hours, with the delivery date stated alongside the price so the commitment covers both. First issues include a markup round, drawings ship in native DWG or model format plus PDF, and revision control is maintained across the engagement so there is never a question about which drawing is current. If a job is outside our capability or timeline, we say so at the quote stage — a declined job costs you a day; a badly delivered one costs you a project.

Turnaround and how work is prioritised

Standard turnaround runs from same-week on single drawings to two to four weeks on multi-discipline packages, with the delivery date fixed at quote alongside the fee. Urgent work is accommodated honestly: if a deadline is achievable it is committed to in writing, and if it is not we say so before you commit — a missed deadline discovered at delivery is the most expensive kind. Progressive issue is standard on larger sets, releasing the sheets your project needs first while the remainder completes, and every engagement closes with native files handed over, not held hostage. Recurring clients can hold their drawing standards, title blocks and layer conventions on file with us, so every new job starts on their template from sheet one — a small setup that compounds across dozens of drawings a year.
