Steel and precast detailing, answered

Steel detailing turns an engineer’s design drawings into shop drawings, erection drawings and machine files a fabricator uses to cut, drill, weld and assemble each steel member. A detailer models the whole structure in 3D software such as Tekla Structures, resolves every connection, and issues drawings for each assembly and part.

Precast detailing produces the shop drawings used to cast concrete panels, columns and beams off site. Each drawing shows the element’s dimensions, reinforcement, cast-in plates, lifting and bracing inserts and openings, so the precaster can build the mould and pour without guesswork.

Shop drawings show how each member or panel is made: dimensions, holes, welds, reinforcement and cast-ins. Erection drawings show where each piece goes on site, using piece marks, grid references and the installation sequence.

Send the structural and architectural drawings (IFC or latest revision), any 3D models and the specification. Tell us your required deliverables and dates. We reply with a fixed-scope quote and programme.

It depends on tonnage, complexity and how complete the design is. A small portal-frame shed can be issued within days; a multi-storey commercial frame is staged by level or zone so fabrication can start while detailing continues. We confirm a programme with every quote.

Torvane is based in Indonesia. We detail for steel fabricators and precasters in Australia, New Zealand, the United States, Canada, the United Kingdom and Indonesia, to each market’s codes, section catalogues and drawing standards, in metric or imperial.

Our primary platform is Tekla Structures, with Advance Steel, AutoCAD and Revit available. We exchange models in IFC and deliver NC1/DSTV, DXF and KISS files for CNC machinery and MIS software.

We model connections to the engineer’s loads and standard details and coordinate calculations for review. Final design responsibility and sign-off stay with the project’s structural engineer.
