Module architecture
Define repeatable grids, dimensions and connection zones.
FlexiBuild · DfMA · Assembly
Modular construction.
Use volumetric, panelised and modular solutions where they create programme, quality, logistics and lifecycle value—engineered as part of the building rather than treated as an afterthought.
Modular delivery
Assemble more of the building before it reaches its final position.
FlexiBuild coordinates modular units and assemblies with the structure, envelope, services and site works required for efficient installation.
- Volumetric modules
- Panelised systems
- Service and plant modules
- Repeatable structural bays
- Planned lifting and connection details
- Coordinated site and factory programmes
Big Three × FlexiBuild
Modularity is an engineering decision, not a visual style.
The modular strategy is selected around programme, transport, structural system, services, lifting, repetition and long-term adaptability.
Big Three coordinates foundations, civils, structural interfaces and site enabling works while FlexiBuild coordinates the modular building system and production sequence.
B3 Nexus maintains visibility from design and manufacturing through logistics, installation, inspection and handover.
Delivery system
Engineer the module and the site as one system.
Modular construction works when production, transport, lifting and final integration are designed together.
Structural interfaces
Coordinate loads, support points and connection tolerances.
Services integration
Pre-coordinate electrical, mechanical, plumbing and controls.
Transport envelope
Design around practical shipping dimensions and protection.
Lift planning
Engineer crane access, rigging, sequence and temporary stability.
Final integration
Close interfaces, commission systems and capture handover evidence.
Connected capabilities

Frequently asked questions
How Big Three Engineering and FlexiBuild connect digital engineering with industrialised physical delivery.
What is modular construction?
Modular construction uses repeatable manufactured sections or assemblies that are completed to a defined level off site and then installed and integrated on site.
Is FlexiBuild limited to volumetric modules?
No. The system can combine volumetric, panelised, structural, service and component-level modularisation depending on the project.
What does Big Three Engineering do in a modular project?
Big Three connects modular design to civils, foundations, structures, utilities, logistics, site delivery, inspection and overall project controls.
How is modular delivery tracked?
B3 Nexus can connect design status, manufacturing milestones, logistics, lifting, installation and quality evidence.
Design the building for assembly.
Bring modular strategy into the project before interfaces and logistics become fixed.
