Prefabrication in #CivilEngineering | @3DSAEC
Prefabrication is the designing and manufacturing of assemblies under factory conditions, then transporting them to—and assembling them on—a construction site. The technique is most widely used for concrete and steel sections in structures where a particular part or form is repeated many times.
In civil engineering, prefabrication plays a key role in the construction of bridges, roads, tunnels, and more. Prefabrication can be used for:
- cantilevered decks of elevated bridges in highway projects
- parapets of expressways and road curbs
- precast girder units and beams for elevated roadways, tracks, viaducts, and pedestrian footbridges
- decks for long span bridges
- tunnel linings, especially for tunnels formed by tunnel boring machine
- sea walls
- railway platforms
- noise barrier panels
- overhanging ducts and service channels for underground facilities
- storm water discharge culverts
- and many other elements of a civil design project
Contributing Factors to the Prefabrication Trend in Civil Engineering
The main reasons for prefabrication construction is to reduce the overall time period of construction time on a project. This time savings can yield significant budget savings.
