Structural steelwork detailing service


Our steelwork detailing service uses the latest Building Information Modeling (BIM) 3-D structural steel detailing software to automate the production of drawings, bills of materials (BOM) and computer controlled machinery NC files. This drastically increases productivity and drawing quality, while reducing the risk of errors.


After we produce the intelligent 3-D model we can provide the following:

  • Electronic copies of 3-D models for visualisation by Architects & Structural Engineers
  • General arrangement & 3-D drawings (In AutoCAD & PDF formats)
  • Fabrication / shop drawings
  • Materials, bolts & loading lists
  • Files for CNC machinery (Saw/drill lines and laser/plasma profile cutting machines)
  • Un-folded plate development drawings
  • Electronic and paper copies of all drawings and data

Typical projects include:

  • Structural steel buildings
  • Mezzanine floors
  • Platforms & bridges
  • Machinery & plant support structures
  • Canopies & glass support structures

Tender 3-D models & materials lists:

We can help you to win tenders for steelwork contracts by producing a 3-D model & generating a list of all materials required for the project. This service helps to ensure you accurately cost the raw materials and predict production & installation lead times etc
