Many small contractors are reluctant to adopt IBS system and prefer to continue using the conventional method of construction. This is due to the fact that small contractors lack of financial backup and are not able to set up their own manufacturing plants as it requires huge investment capital. In this case, financial issues become the main obstacle for small contractors to move forward with the IBS system (Rahman & Omar, 2006). In the perspective of components’ manufacturer, IBS construction requires high initial investment capital for them to purchase new machinery, mould, importing foreign technology and wages of skilled operator for installation process (Thanoon et al. 2003). 2.3 Low Standardisation of components Low standardisation of components also hinders successful use of IBS. The tailor-made components which do not fit into another project will increase initial costs due to the cost of the mould and design. Lack of standardisation was due to a lack of a certification and accreditation scheme on IBS and the poor response to Modular Coordination (MC) promotion under MS 1064. Modular Coordination (MC) is defined as a coordinated unified system for dimensioning space, components, fitting, etc. so that all elements fit together without cutting or extending even when the components and fittings are manufactured by different suppliers (Trikha, 1999). The dimensional control of building is very important because it is necessary to place the building parts so they can fit and function properly. In the conventional construction practice, the control of dimension is relatively simple. However, due to the industrialization of construction scenario, the structural component is prefabricated. The dimensional coordination of these components is importance. The full benefit of industrialization is impossible without standardization. No effective standardization is possible in the building industry without dimensional coordination (Warszawski, 1999).>
