INNOVATIVE PREFABRICATED CONCRETE CONSTRUCTION-44-LEVEL STUDENT ACCOMMODATION BUILDING IN MELBOURNE

摘要

This paper explains how the innovative prefabricated and in situ concrete horizontal and vertical in-itu structural tongue pints of Hickory Building Systems (HBS2) have enabled the construction of a 44-level high-rise student accommodation building in Melbourne. In this innovative construction method, the building was manufactured off-site in prefabricated sections, then transported to the construction site and assembled. This application is one of the first examples of integrated, prefabricated construction, which differs from the more common, panelised modular systems and is more comparable in capability to conventional cast in situ construction systems. The key structural elements are the prefabricated slab elements with horizontal tongue and temporary recyclable prop, prefabricated slab elements with preassembled facade with accurately locatable temporary props. The key benefits of this type of construction method are examined in this paper, including: 1) The effect on quality caused by performing work in a controlled factory environment, which reduces downtime due to inclement weather and allows quality control checks to be implemented more effectively compared to conventional cast in situ construction. 2) The reduction in building time and labour required as compared with a conventional on-site approach. 3) The increase in safety by reducing the need to work at heights and removing the live edge from site by preinstalling the facade and pouring the building slabs off-site. 4) The effect of delivering materials to the point of fabrication had on on-site construction logistics.
