ADOPTION OF THE INDUSTRIALIZED BUILDING SYSTEM FOR HOUSING DELIVERY IN NIGERIA.
The construction sector based on industry or Industrialized Building System (IBS) is a method of construction using the industrialized building materials at the manufacturing plant. This method can replace the conventional method and is able to; reduces the amount of foreign labor, improve the quality of construction, lower the cost, and reduce construction time. This study is intended to create a guideline that can be used to encourage all private construction projects in Nigeria to implement the IBS System in 2015. Therefore, this study was undertaken to assess the level of IBS usage in the building construction.
- Background of the study
Industrialized Building System is an advancement of the new construction technology for the time being. It is an alternative of construction that can change many aspects in building construction. The industrialized building system is a construction system that is built using pre-fabricated components and is systematically done using machine, form works and other forms of mechanical equipment (Rahman & Omar, 2006). The components are manufactured offsite and once completed will be delivered to construction sites for assembly and erection (Rahman & Omar, 2006). It is also can be interpreted as a system which component is manufactured in factory and then installed on site based on the size and dimension of the component required. Furthermore, a system in which concrete components, prefabricated at site or in factory are assembly to form the structure with minimum in situ construction (rikha, 1999).
Industrialised Building System (IBS) is a term used in Malaysia for a technique of construction where by components are manufactured in a controlled environment, either at site or off site, placed and assembled into construction works. Worldwide, IBS is also known as Prefabricated/Pre-fab Construction, Modern Method of Construction (MMC) and Off-site Construction. CIDB Malaysia, through IBS Centre is promoting the usage of IBS to increase productivity and quality at construction sites through various promotion programmes, training and incentives. The content of IBS (IBS Score) is determined based on the Construction Industry Standard 18 (CIS 18: 2010); either manually, web application or fully automated CAD-based IBS Score calculator. IBS was first introduced in mid-sixties with the Circular Road Flat construction project that used pre-cast concrete; this was government’s beginning effort to use this smart method in public project (CIDB 2003).
