Workspace collisions are the result of the unplanned overlap of resources and have proved to seriously impact the projects’ performance. Yet till date, and despite the improvements of 4D modeling in the construction industry, workspace management is mostly performed manually or via 2D sketches, which fails to cover the workspaces’ evolution properly. The lack of 4D implementation may be attributed due to the additional efforts that is exerted to create workspaces and simulate their movement which is due to: (1) the diversity of the previous works and lack of standardization (2) the lack of comprehensive implementation of any approach through multiple construction domains and (3) the lack of a stochastic approach to consider the variability of workspaces. Accordingly, this paper presents an industry questionnaire created to better understand the market’s perspective and needs for a workspace management tool. The questionnaire covers the industry’s views on the inputs and outputs mode detection and avoidance, the ranking of domains for the need of workspace management and verifies the necessity for a stochastic approach. 41 respondents replied, whom 92% have suffered from workspace collisions, and indicate that productivity was the most impacted project aspect. They also indicated that industrial projects are the most sensitive domain towards workspace collisions, and over 85% recommended stochastic approaches for workspace modeling and to consider crew specific attributes in the resolution strategies.
