The modern concept of prefabrication, which mass produces uniform panels and components, dates back to the early 1900s.
A bridge ramp that can go up or down.
By the use of sophisticated geometric design and prefabrication techniques.

THIS IS NOT GOOD FOR ENGINEERS WHO CHANGES HIS MIND EVERYDAY AND ALL THE PROVISIONS FOR ALL SERVICES WILL BE AFFECTED.
*Prefabrication* is the practice of assembling components of a structure in a factory or othermanufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out.
Architecture, assembly, build, conception, development, fabrication, manufacture, prefabrication and erection are all synonyms of the word construction.
Some things an engineering presentation on steel detailing could look at are: * Earthquake strengthening using steel * Construction details that express the structural load paths * steel detailing through history as technology changes * steel and corrosion * steel combined with other materials in details * prefabrication using steel * steel as fasteners
The prefabrication structure of building components can significantly increase construction if it is carried out in an organized way. The main advantage is that systems and components require time and labor to complete and are scheduled for short installation times. Much of the equipment and fixtures in a typical building are prefabricated, such as casework, mechanical equipment, electrical equipment, and more. Much more is partially prefabricated, such as trusses for roofs or bar joists and structural steel, which is precut, partially assembled, and detailed with anchor bolt layouts or other critical measurements provided by the supplier. Disadvantages come when prefabricated structures donβt fit right, and it becomes difficult to transport from the fabrication location. Also, some components might get damaged in handling or shipping, or they may not be built correctly. It is common, for instance, for a structural steel beam to have a connection plate welded to it at the wrong elevation or on the wrong site. Still, careful, accurate detailing and fabrication can avoid this problem.

There are five significant benefits of BIM in the design and construction process: Cost and resource savings. Greater efficiency and shorter project lifecycles. Improved communications and coordination. More opportunities for prefabrication and modular construction. Higher quality results.
