	Ergonomics eTool: Solutions for Electrical Contractors - Prefabrication
		There are also a number of ergonomic benefits to prefabrication, such as controlling work heights, supporting tool weights, and controlling environmental conditions.
		While some ergonomics-related risk factors can be controlled through prefabrication, it may create other job-specific hazards including heavy manual lifting, repetitive movements, awkward or static postures and contact stress.
		Employees should be aware of the potential hazards that are unique to a prefabrication setting.

	Prefabrication - Wikipedia, the free encyclopedia
		Prefabrication is the practice of manufacturing the parts of an assembly in one location, ready for them to be assembled in another place.
		The practice was widely used in the construction of prefabricated housing during the 20th century, providing a product made in factory conditions that would save time on site and, at least in theory, improve quality.
		Prefabrication is also used for many other types of constructions, because it saves engineering time on construction site, which is often delayed by bad weather.

		Prefabrication by its very nature removes a significant level of on-site activity and inefficiency.
		For example, prefabricated plant units and riser modules are required to be self supporting and thus additional steelwork bracing and supporting bracketry can prove to be more costly than a traditional on site installation.
		Prefabricated concrete bathroom pods are formed off-site and the whole bathroom shell becomes one integral bonded unit.

	KTA [ Prefabrication and Sustainability ]
		Prefabrication also offers other savings in both time and money that can either be passed on directly to the buyer or used to finance sustainable systems that have high initial capital costs but offer long term benefits.
		Prefabrication lends itself to recycling of the buildings themselves as well, since factory-built elements are more easily removed and interchanged and components can be designed with whole life cycle costs taken into account.
		It is interesting to note that the shortage of skilled labor, coupled with an aging workforce less able to cope with the environmental variability of the jobsite, is considered to have been a major driver in the development of the prefabricated housing industry in Japan and Central Europe [3].

	Farm structures ... - Ch6 Building production:The building production process-Methods of ...
		Prefabrication is the manufacture of building components either on-site (but not in-situ) or off-site in a factory.
		For example, the use of prefabricated lintels may save formwork and result in continuity in the bricklaying work, but would be uneconomical if a lifting crane is required at the site to place them, when it is not required for any other purpose on the job.
		Prefabrication eliminates the waiting time for concrete components to harden sufficiently for subsequent on- site operations to continue, but the weight and size of concrete parts may make prefabrication impractical.

	Prefabricated Bridge Elements and Systems - Innovative Projects to Improve Construction Zone Safety
		Prefabrication of the center span greatly improved constructability for OandG Industries; the center span could not have been built during the limited working hours allowed by the rail yard.
		With prefabrication facilitating faster construction, bridge users were spared several months of inconvenience, and IH70 users were spared a period of reduced vertical clearance.
		The contractor was able to meet scheduling constraints by using prefabricated deck panels-a large transport device moved the new panel to the top of the bridge, removed the old panel that crews had just cut out, and then lowered the new panel into place before taking the old panel off the bridge.

		Prefabrication of masonry to date has not achieved the economy of construction originally desired on flat wall areas.

	Prefabrication of Timber Buildings based on Digital Models : AECBytes Feature
		One of the important characteristics of wood-based construction is its suitability for prefabrication.
		These specialized systems for prefabrication could be customized for different materials, different building types, different methods of construction, and so on, and could include all the associated information needed for the analysis of cost, structure, energy performance, and so on.
		If this technology was available and used even for partial prefabrication today, it would help to dramatically reduce the construction time of a project and make it far more efficient and cost-effective than the linear, on-site, one-off construction methods that continue to be the norm in the building industry.

	Timber volume element prefabrication: production and market aspects
		Timber prefabrication is argued to be a possible catalyst for improvements towards industrialization and process orientation in Swedish housing construction.
		It is argued that timber volume element prefabrication has the possibility to increase structure and hence the building system can serve as a platform for transfer of management principles from manufacturing to construction.
		To obtain increased use of timber prefabrication and thus potential development in housing, this study indicates that there is a need for increased information transfer to potential customers to obtain trust towards the timber manufacturers and the building systems.

	March 2006 Focus - Prefabricated Bridge Systems: A Decisionmaking Tool
		The use of prefabricated bridge elements and systems, ranging from superstructures or substructures to totally prefabricated bridges, offers faster and safer bridge construction and better quality.
		Prefabricated bridge systems are manufactured offsite at a prefabrication plant or adjacent to the project site by the contractor, under controlled conditions, and brought to the bridge location ready to install.
		Among the lessons learned on the projects to date is the need to familiarize contractors and other industry personnel with the process, involve contractors and prefabricators in the design process, and consider construction issues, such as staging areas needed, work hours required, and contingency plans.

		With this method of construction the pieces of the structure are fabricated in factories where there is greater precision and a potential cost savings in their manufacture.
