DfMA Ventilation Shaft and Adit Example
An example of integrating design, off-site manufacture and rapid on-site assembly for ventilation shaft and adit works.

This example reflects the use of DfMA principles to coordinate design, manufacture and installation for complex underground ventilation-related structures.
By moving a greater proportion of work into factory-controlled production, on-site assembly can be accelerated while improving tolerances and quality consistency.
Scope
- • Planning for precast ventilation shaft and adit components
- • Factory production and site interface coordination
- • Control of installation tolerance, programme and quality
