In order to use IBS, contractor must change. It is important to move from existing contracting role into IBS system integrator
First and foremost, the success of IBS depends on securing ‘top-down’ corporate vision and corporate motivation on IBS. This in return will ensure the right motivation and commitment from the whole team
Contractors should not only depend on knowledge in construction/ installation. Contractors must build up knowledge and capacity in design and construction. Whenever possible, contractors are suggested to have their own prefabrication facilities.
The critical factors to IBS lie in good site management, planning and control of overall process in project life cycle. This in turn, leads to recommendation that experienced and well-trained workers are the critical.
Key decisions on strategy, application, design, logistic and detail unit should be made as early as possible between all parties involved. IBS should not be used as an afterthought, or as a late solution to shorten construction time, but rather as an integral part of the design from the earliest possible stage of the project
Coordination IBS processes is vital. Careful attention need to be paid to pre-planning and scheduling
High demands will be raised on the management of IBS supply chain and logistic activities. Contractors need effective management of supply chain. It needs to be constructed in a manner that allows the contractors gain the full control of the process with the intention to improve efficiencies and competitiveness
Effective communication channel across the supply chain need to be established in order to coordinate IBS process
The management of logistic is critical element to IBS and the importance of logistical considerations is not to be underestimated by contractor
The use of Just in Time (JIT) and Lean Construction approach are recommended to be applied in IBS whenever possible
ICT is reliable support tool to improve communication between project team and as a medium for quality control of overall IBS project deliveries.
Successful IBS implementation depends on organisation ability to expedite learning curve from one project to another. Therefore, continues improvement and learning can develop company understanding on the processes and the principal behind it as the knowledge will multiply as experience mount up
Successful IBS requires partnership and close relationship with suppliers and sub-contractors from the early stage of project sequences
Improvement in procurement strategy and contracting is important in order to achieve long term success in offsite. The negotiations, procurement and contract should allow the contractors and manufactures to contribute their knowledge, experience of design, construction and planning of the building
