4. Discussion
4.1. Component 1: Stakeholder’s interests
The first significant factors for driving adoption of MCM in a building project are closely related
to the component determined ‘Expanding stakeholder’s interest’. The percent of variance explained by
this component is 31.948% (as shown in Table 3). The component 1 included the interest in developer
and government about modular construction as well as experts in modular design and construction.
The stakeholder’s interest plays an important role in driving the project smoothly [20]. Meanwhile, the
economic benefit is a critical issue that will not only lead to gain the willingness of the stakeholder but
also reflect market availability [21]. Thus, it is very important to induce the application of this method
by emphasizing the time and cost advantages of the modular construction method. As a result, for
improving the stakeholderʹs attentions, various advantages about the modular method should be
