Glossary of Construction Terms

What is Prefabrication or Prefab?

It refers to any part of a building that has been fabricated at a place other than its final location.  For this reason, it can be referred to by other names such as off-site fabrication, off-site construction or off-site manufacture. Prefab is short for prefabrication. Prefabrication is an ‘umbrella’ term and it covers a range of different systems and processes.  These will include structural, architectural and services elements.

What is MMC (Modern Methods of Construction)?

'Modern Methods of Construction' is an output of the MHCLG Joint Industry Working Group from the UK. Spanning all types of pre-manufacturing, site based materials and process innovation, MMC enables a "full and future-proofed" framework of seven categories to better understand regularised terminology. The categories include: Pre-manufacturing (3D primary structural systems)Pre-manufacturing (2D primary structural systems)Pre-manufacturing components (non-systemised primary structure)Additive manufacturing (structural and non-structural)Pre-manufacturing (non structural assemblies and sub-assemblies)Traditional building product led site labour reduction / productivity improvementsSite process led site labour reduction / productivity [...]

What is DfA (Design for Assembly)?

Design for assembly (DFA) is a process by which products are designed with ease of assembly in mind. If a product contains fewer parts it will take less time to assemble, thereby reducing assembly costs. In addition, if the parts are provided with features which make it easier to grasp, move, orient and insert them, this will also reduce assembly time and assembly costs. The reduction of the number of parts in an assembly has the added benefit of generally reducing the total cost of parts in the assembly. [...]

What is DfM (Design for Manufacturing)?

Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology. DFM describes the process of designing or engineering a product in order to facilitate the manufacturing process in order to reduce its manufacturing costs. DFM will allow potential problems to be fixed in the design phase [...]

What is DfMA (Design for Manufacture and Assembly)

DFMA stands for Design for Manufacture and Assembly. DFMA is the combination of two methodologies; Design for Manufacture, which means the design for ease of manufacture of the parts that will form a product, and Design for Assembly, which means the design of the product for ease of assembly.
