Design for manufacture
Resolve geometry, tolerances, interfaces and repeatability before fabrication begins.
Advanced Engineering · DfMA
Engineer more. Manufacture more. Assemble faster.
Design for Manufacture and Assembly (DfMA) shifts suitable work away from variable site conditions and into controlled fabrication and preassembly—then coordinates transport, lifting, installation and inspection through the engineering model.
Quick answer
What is the Big Three DfMA approach?
The principle is to design infrastructure and building packages for controlled manufacture, efficient preassembly and coordinated site installation, improving repeatability, quality, programme control and constructability.
- Prefabrication and preassembly
- Modularisation and standardised interfaces
- Precast and structural steel assemblies
- MEP racks, plant skids and service modules
- Factory testing, logistics and installation planning
Big Three innovation model
Industrialise the work that does not need to happen on site.
Applications include precast structural elements, reinforcement cages, structural steel assemblies, façade systems, modular MEP racks, plant-room skids, pump stations, substations, containerised treatment plants, pipe assemblies, culverts and modular site infrastructure.
Nexus connects the digital chain from design and tolerances through quantities, fabrication, logistics, lifting, installation, inspection and the final asset record. The focus is a better construction method built around repeatability, controlled production, logistics and efficient assembly.
Connected capabilities
How this fits into the Big Three delivery model.
Each capability strengthens engineering decisions, construction execution, evidence and lifecycle value across the project lifecycle.
Controlled production
Move suitable work into factory or workshop conditions for better quality and repeatability.
Preassembly
Combine components before site delivery to reduce site labour, interfaces and working-at-height exposure.
Logistics engineering
Coordinate transport envelopes, laydown, cranes, lifting studies and installation sequence.
Rapid installation
Use repeatable connections and planned assembly methods to reduce final-site duration.
Digital traceability
Connect fabricated components to model information, inspection, installation and asset records.

Frequently asked questions
Practical answers about how Big Three Engineering connects digital engineering with physical delivery.
What does DfMA mean?
Design for Manufacture and Assembly means engineering suitable components or modules so they can be efficiently manufactured or preassembled and then installed on site.
What infrastructure can be modularised?
Applications include precast elements, steel assemblies, MEP racks, plant skids, pump stations, substations, treatment modules, pipe assemblies, culverts and site infrastructure.
How does modular construction improve delivery?
Modular construction moves repeatable work into controlled production, reduces site interfaces, coordinates logistics and lifting earlier, and shortens the amount of work that must happen under final site conditions.
How does Nexus support DfMA?
Nexus can connect design, tolerances, quantities, fabrication, logistics, installation, inspection and the final asset record through one digital thread.
