Digitalized and User-Centered System for Construction Site Layout Planning and Assessment

This study addresses project managers' challenges in drafting, evaluating, and communicating construction site layout plans (CSLP) due to the need for a specialized CSLP system. It highlights the absence of a scientific methodology in identifying system requirements and designing user interfaces for such systems. Thus, this study applied the design science research methodology to propose a design of the digitalized and user-centered CSLP system. By understanding the CSLP creation process, this study identified 12 key functions of a CSLP system through a literature review, focus group interview, and expert survey. The user interface was designed to align with these functions and the CSLP process. A prototype was developed and validated through eight case studies, demonstrating high usability and applicability, rated at 4.0 and 3.9 on a Likert scale. This study contributes theoretical and practical insights into CSLP system development, offering knowledge of system requirements and design strategy.
