Steel fabrication drawings Melbourne logistics warehouse.
Case study: full structural steel detailing for an 18,000 m² logistics warehouse in Melbourne’s west — 980 tonnes of structural steel including portal frames, mezzanine, crane runway and dock structures, modelled in Tekla and detailed to AS 4100.

Project overview
An East-Melbourne structural steel fabricator engaged ASTCAD for the detailing of an 18,000 m² logistics warehouse in Melbourne’s western industrial corridor. The project included tapered portal frames, a 1,200 m² office mezzanine, a 20-tonne crane runway through the centre bay, and 32 truck dock structures.
The challenge
The fabricator required Tekla-native detailing to feed their CNC profile cutting and beam line. The architectural intent required exposed primary steel inside the office mezzanine, requiring high-quality finish welds and concealed connections. The 32 dock structures had to be detailed as a repeatable assembly to minimise variation.
Our approach
- Tekla Structures model with discipline coordination via IFC
- Connection design to AS/NZS 5131 CC3 for primary frames
- Concealed shear-tab connections at exposed mezzanine columns
- Standardised dock structure as a single repeating assembly
- Bolt list and weld map generation directly from the Tekla model
Deliverables
- 1,840 shop drawings across all elements
- Tekla model deliverable for CNC integration
- Comprehensive bolt list (over 142,000 bolts)
- Erection drawings and rigging arrangements
- AS/NZS 5131 fabrication category documentation
Outcome
The fabrication programme ran on schedule with zero re-fabrication of incorrectly detailed members. The fabricator reported a 22% reduction in detailing-related shop queries compared to their prior project. The warehouse opened to lease in November 2023.
