COMPARISON OF THE USE OF TRADITIONAL AND LOW WASTE FORMWORK SYSTEMS IN HONG KONG

Formwork is one of the most important temporary works for construction of reinforced concrete superstructure in building projects. The use of conventional timber formwork dominated the construction market in Hong Kong for many years. Nowadays, low waste construction technologies for superstructure construction are commonly adopted. The most commonly used low waste construction technology in Hong Kong is large panel steel formwork integrated with pre-cast concrete units. Compared with the use of conventional timber formwork system, the latter is considered a more sustainable construction method.
