Design For Manufacture – A Buildings Approach
Content-rich BIM and First Steps from Design for Manufacture Joseph Thiang 28/10/2019Brisbane, Australia
Design For Manufacture – Definition
Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture
- Typical Reinforcement drawing
- Difficult to read multiple layers
- Often not fully co-ordinated
- Refer to typical details and sections
Design For Manufacture – Where is it standard?
Where I started thinking about DFM…

o 443 Queen St – 48 Storey Premium residential tower
Transfer deck:
o 1.5 to 2m deep
o 2500m2 in area
o Supports and transitions residential walls through to carpark columns – upwards of 40 storeys of load

Contractor/Subcontractor Input| Workshops
o Trimble Connect (.ifc files) + Rhino-Enscape with VR through HTC Viveo Steel fabricator, scheduler, formworker, contractor, engineers, hydraulics subcontractor (plumber)o Facilitated constructability discussions in workshops – sequencing, 4Do Allowed more visibility of complex geometry by setting up layers/filterso Co-ordination with serviceso Address safety issues – bar hazards, formwork issueso Appreciation of scale and complexity
How was it used?| VR/Trimble Con.

Final deliverable | Outcomes
How did it benefit the project? And Arup?
o Anticipates site co-ordination issues earliero Facilitated better construction planningo Achieves better overlap of design with constructiono Allows better collaboration with Contractor and Subcontractorso Answer RFIs before arriving on site – rather than holding up
site
Opportunities – deeper collaboration
