Structure
Repeatable frames, bays, floors and connection families.
FlexiBuild · Kit of Parts
Turn repeatable construction scope into a coordinated kit of parts—configurable structures, envelopes, service systems, modules and interfaces engineered to work together.
Building systems
FlexiBuild organises repeatable components and assemblies into building-system families that can be configured for different project requirements while retaining coordinated interfaces.
Big Three × FlexiBuild
A productised system does not mean every project looks the same. It means the hidden interfaces, component families and technical rules are standardised so design can focus on the parts that genuinely need to vary.
The system can connect architecture, structure, envelope and services to defined manufacturing and installation logic.
B3 Nexus can maintain the configuration, quantities, revision history, production state and installed asset record behind each project.
Delivery system
The building becomes a coordinated system of repeatable elements with clear interfaces and engineering rules.
Repeatable frames, bays, floors and connection families.
Panel and façade systems coordinated with structure and weathering.
Standardised risers, racks, plant modules and connection zones.
Repeatable partition, pod and fit-out assemblies.
Packaged plant, pumping, electrical and control assemblies.
Combine systems according to project-specific functional requirements.
Connected capabilities
From digital engineering and product configuration to controlled manufacture, logistics, assembly and lifecycle information.

Design building delivery around repeatable systems, controlled production and efficient assembly.

How Big Three Engineering and FlexiBuild connect digital engineering with industrialised physical delivery.
It is a family of coordinated components and interfaces that can be configured for multiple projects without redesigning every hidden technical connection from zero.
No. The aim is to standardise repeatable interfaces and components while allowing project-specific planning, architecture and performance requirements.
Structures, envelopes, service modules, partitions, plant rooms, pods, utility skids and other repeatable assemblies can form part of a productised kit of parts.
The project configuration can connect component selection, quantities, revisions, manufacturing status and installed asset information.
Use productisation to create repeatability without losing project-specific engineering.
