Collaboration involves people working together and sharing information toward a common goal. The Architecture, Engineering, and Construction (AEC) industry is known for being the least digitalized and highly fragmented work environment involving many processes across the supply chain. It creates a challenge to encourage collaboration among geographically distributed collaborators. Cloud computing has become more commonly used to outsource data for its efficient storage with timely updates and easy accessibility. Information is available for all collaborators and enables easy sharing and storing for collaborative work in real-time. The benefits of using cloud computing follow up with risks and challenges in usability and security.

     This study aims to investigate and describe construction collaborators’ experiences, expectations, and requirements of cloud services in construction projects concerning information security and usability. The study is based on a qualitative method with its focus on obtaining in-depth information through open-ended semi-structured interviews with seven specialists from the AEC industry.

     Participants’ experiences and thoughts are thematically categorized and analyzed. The result shows that the usability of cloud computing has become an important core for efficient collaboration with features of sharing, storage, and interaction among collaborators. Cloud-based collaborations security is more vulnerable to external attacks than internal human error. International cloud-based collaborations could have legal problems due to the compliance issues of GDPR with international laws.
