Negative perception on IBS
Rahman & Omar (2006) observed that the term IBS is often misinterpreted with negative image due to its past failures and unattractive architecture. These buildings are normally associated with pre-fabricated, mass construction method, low quality buildings, leakages, abandoned projects, unpleasant architectural appearances and other drawbacks. Due to the poor architectural design, the old pre-fabricated buildings have given the public, bad impression about pre-cast concrete. Clients are often in doubt of using IBS because of fear of customer rejection. Even construction professionals are in doubt in IBS technology and relate IBS with a potential post-construction problem. In addition, it is always not popular among the designers as they found pre-fabrication has limiting their creativity in design process (Hamid et al. 2008). It is observed that lack of IBS branding and promotion taking place in the market as the end user are neither misinterpret nor unaware of this construction method. As a result, IBS is not creating enough pull factors to encourage developers to adopt IBS. In comparison, IBS development in Scandinavian and Japan provide higher customer focus and adopt mass-customization of to enrich customer option. In UK, IBS is well associate with sustainability and green construction. Better customer perception will create better understanding and demand and will definitely encourage developers to push for IBS adoption
Loose supply chain integration
Construction is a multi-organization process, which involves client/owner, designer, contractor, supplier and consultant. It also is a multi-stage process, which includes conceptual, design, construction, maintenance, replacement, and decommission. By moving construction activities upstream from the construction site to factories where pre-assembly is carried out, high demands will be raised on the management of the supply chain and logistic activities (Pan et al. 2008) (Blismas, 2007) (Gibb, 2001). In such arrangement the risk involve with any construction quality and tolerance are also clearly identify and the party responsible for taking corrective action is agreed from the outset of a project. Extensive integration requires good IT tools to ensure supply chain continuity and synchronization. Integration also includes developing supplier partnership and establishes clear information flow using IT (Oostra & Jonson, 2007). However, the current state of construction industry is being considered as fragmented where the whole supply chains get their own strategy and agenda. To worsen the situation, IT adoption in Malaysia is still low and contribute to loose supply chain coordination and integration between design and manufacture which is vital to IBS implementation.
