Introduction to off-site construction and construction sequence
Offsite construction is based primarily on two key principles: efficiency and quality. It is defined as the manufacture and pre-assembly of components, elements or modules before installation into their final location on site. The concept of offsite construction is to allow manufacture of parts of the building in an environment best suited for effective production, where advanced equipment can be used to increase productivity.
Furthermore, offsite construction improves working conditions by taking construction processes to a clean controlled environment unaffected by climatic conditions, as well as helping to reduce waste. The more parts of buildings are completed offsite, the less needs to be done onsite.
Offsite construction is based primarily on two key principles of efficiency and quality.
Offsite manufacture may not guarantee greater durability, but factory production should reduce the risk of non-conformities, related premature failures and consequent repairs associated with onsite assembly.
The main risks with offsite construction are: late design changes, loss of factory production slot, failure to meet building tolerance and accuracy requirements and supply failure.
