Factors Influencing Adoption of Construction Robotics in Hong Kong's Industry: A Multistakeholder Perspective

Previous studies have explored the factors to the usage of construction robotics (CRs). However, what is the most important factor affecting adoption of CRs considering multistakeholders? Do different stakeholders share similar interests or concerns? These questions have yet to be answered. Therefore, this study aims at identifying and assessing benefits and barriers affecting adoption of CRs in Hong Kong from a multistakeholder perspective. Factors were firstly identified through a systematic literature review in a scientometric approach and validated through a questionnaire survey. Then, the relative importance of these factors was calculated using mean scores ranking, and the stakeholder groups were segmented using k-means algorithm. As a result, 14 benefit factors and 14 barrier factors were identified. Stakeholders were segmented into five groups based on common interests and concerns. The results present a better understanding for the importance of benefits and barriers affecting CRs adoption in Hong Kong considering the multiple stakeholders both individually and collectively. The findings suggest ways to facilitate the improvement of CRs to be more focused, efficient, and user-oriented. The results also contribute to finding further collaboration patterns between different stakeholders. (C) 2021 American Society of Civil Engineers.
