Terminology Guide

Welcome to the Terminology Guide, your resource for decoding the language of industrialised construction.

This page is designed to bring clarity to the key terms, acronyms and methodologies shaping modern delivery models, offsite manufacture, modular systems and digital workflows.

Whether you are a designer, policy-maker, builder or supply-chain partner, a solid grasp of this vocabulary ensures stronger collaboration, sharper briefs and more informed decision-making across the entire built-environment ecosystem.

 

Term Definition Context for Industrialised Construction
Aggregated Procurement Coordinating multiple projects or clients to procure standardised systems in bulk, providing stable demand for manufacturers. Encourages manufacturer investment, lowers unit cost, and drives repeatability.
Building Information Modelling (BIM) The process of creating and managing digital representations of the physical and functional characteristics of a facility. Serves as the data backbone for IC. Open BIM standards (IFC, COBie, ISO 19650) ensure interoperability across platforms and supply chains.
Circular Design Designing products and systems for reuse, re-manufacture, and disassembly at end of life. Embedded in IC systems to support net-zero carbon and material efficiency goals.
Design for Manufacture and Assembly (DfMA) A design methodology that focuses on simplifying the manufacturing and assembly processes of building components and systems. Ensures that buildings are designed to be manufacturable in a factory and installable efficiently on site, reducing rework, waste, and risk.
Digital Twin A dynamic, data-rich digital replica of a physical asset, system, or process that is updated throughout its lifecycle. In IC, digital twins link design models, manufacturing data, and operational performance — enabling predictive maintenance and circular lifecycle planning.
Golden Thread A continuous, dependable digital record of information and documents relating to a building (or asset) across its full lifecycle—from design and construction through to occupation, maintenance and eventual decommissioning. In the wake of heightened regulatory and safety expectations (for example under the Building Safety Act 2022 in England), the golden thread has become a core requirement for higher-risk buildings and increasingly for mainstream assets.
Gemini Principles A set of guiding values developed by the Centre for Digital Built Britain (CDBB) and the Digital Framework Task Group to underpin the development of the national digital twin and associated information-management frameworks. The Gemini Principles provide a normative framework for the use of digital models, data-sharing, asset life-cycle integration and connected systems.
Industrialised Construction (IC) The application of manufacturing principles, digital processes, and standardised systems to the design, production, and assembly of buildings and infrastructure. Encompasses offsite manufacturing, DfMA, modularisation, automation, logistics integration, and digital data exchange to improve productivity, quality, and sustainability.
Kit-of-Parts An engineered system of separate standardised, often pre-manufactured parts or modules which are conceived, produced off-site, then assembled on site into a building or asset. This approach underpins the platform-based delivery model: it enables repeatability, flexibility and scalability by treating building assemblies as configurable blocks rather than bespoke elements. Links tightly with MMC, standardisation and industrialised supply-chain thinking.
Modern Methods of Construction (MMC) A collective term for a wide range of building methods designed to be more efficient and effective than traditional brick-and-block construction. MMC represents a shift from bespoke, labour-intensive site construction toward repeatable, factory-influenced production and streamlined assembly.
Offsite Manufacturing (OSM) The production of building elements, modules, or systems in a controlled factory environment prior to on-site assembly. A core delivery method of IC, encompassing volumetric modular, panelised, and sub-assembly manufacturing (e.g., MEP corridor modules, bathroom pods, plant skids).
Open BIM A collaborative approach using non-proprietary data formats and standards to ensure interoperability between software platforms. Enables integration between AEC design tools, manufacturing systems (MES/ERP), and asset management systems.
Performance-Based Regulation A regulatory approach focusing on achieving measurable performance outcomes rather than prescriptive methods. Essential for approving productised systems, allowing innovation while ensuring safety and quality.
Platform Construction / Product Platform A set of repeatable components, interfaces, and design rules that can be combined to produce multiple building types. Enables “mass customisation”: different buildings (schools, homes, hospitals) using a shared kit of parts. Aligns with UK Platform Rulebook initiatives.
Productisation Converting bespoke building elements into standardised, repeatable products with defined performance, cost, and digital data attributes. Allows components and systems to be catalogued, procured, and reused across multiple projects — supporting aggregation of demand and manufacturing investment.
Type Approval Pre-certification of a product or modular system against a set of regulatory and performance standards. Provides assurance that repeatable systems meet compliance without requiring full re-approval for every project.
