This research is collected data from designer, constructor, owner, and supplier who is in related field by using interview and questionnaire. The result shows that precast concrete in panelized system is evaluated to the top of IBS score. In addition, Internal and external factors (Strength, Weakness, Threat, and Opportunity) of Thailand’s construction industry is collected and evaluated. For The result of internal factor found that the potential of contractor is strength, but designer doesn’t aware of IBS concept. For the external factor found that the demand of construction is opportunity for using IBS but the lack of supporting policy from the government is threat.
