A generic term applying to factory preassembled products (usually building services) that would otherwise be assembled onsite. A typical example is a hand basin fitted with taps and waste.
Part of a building or structure that could be considered for standardisation and offsite production such as foundations, structural frame, envelope, services, internals and modular units.
The external walls and roof that form the perimeter or enclosure of a building. Walling may include lightweight curtain walling, in aluminium, steel or glass, or heavyweight components in concrete, brick or stone.
Roofing includes flat or pitched roofs. The extent of offsite manufacture will vary between systems, e.g. for curtain walls:
Applies to pre-cast concrete elements of a structure. This includes wall and floor elements, ceilings, staircases, columns and beams. Also, FEC elements can include building service containment routes, window and door openings and possibly thermal insulation.
Pre-cast concrete systems can be used to construct foundations rapidly. The elements are usually to a bespoke design and cast in a factory environment.
These systems improve productivity, especially in adverse weather conditions, and reduce the amount of excavation required - particularly advantageous when dealing with contaminated ground.
Offsite foundation techniques also include steel mini piles and helical screw piles.
The term "Frame" typically refers to the structure of a building and may be constructed from many different materials. Also, the term may be used to describe the supporting structure for a pod or other volumetric unit.
This section includes descriptions for several terms related to frames and framing.
Currently rarely used in technique comprising panels of lightweight concrete blocks with glued joints fabricated offsite and crane lifted into position onsite.
Attractive with design appeal, glulam beams provide large-span structures without supporting columns, with lots of natural light. Glulam is a strong and sustainable alternative to concrete or steel beams. Made from layers of parallel timber laminates glued together, glulam sections are now frequently used in the construction of all types of building including supermarkets and swimming pools.
Wash hand basins, urinals, lavatories assembled offsite into the “units” with a range of blackboards, taps etc. Most units are designed to be removed and replaced with new unites once they have reached the end of their serviceable life.
Light gauge steel frame is a fundamentally important material to offsite construction. Structural panels assembled from cold-formed galvanised steel sections can be used in a wide range of building types and in hybrid situations with timber and other materials. Light gauge steel framing can be used for a building’s full frame but also for a variety of roofing, modular options and infill walling applications.
