Specification
• Define design, material and quality requirements
• Ensure configuration and performance can be met realistically
• Good knowledge of the design standards• Industry experts should be consulted to
ensure that problems are not repeated• Operators and maintainers should review
![Page 15: Procurement of bulk materials handling machines](https://reader036.vdocument.in/reader036/viewer/2022062412/587b2af21a28ab057d8b5067/html5/thumbnails/15.jpg)
• Common practice for shiploaders • Now possible for land based machines such as
stackers and reclaimers • Considerable savings in onsite labour. • Allows procurement from overseas where
costs are lower than in Australia. • Include transport load cases and sea
fastenings
Modularisation

Overseas procurement - lessons• Detailed review of specifications pre award• Australian Standards discussed pre-award• Review of the 3D model is needed• Adequate translation resources needed • Access design considered throughout the
design phase, not at the end.• Supplier design 100% prior to placing orders • Constructability review of design
