Abstract
Time-space conflicts in construction projects present significant challenges to project scheduling and productivity. Traditional approaches often treat overlapping tasks as homogeneous, failing to account for the unique attributes of individual activities and the complexity of space-sharing conflicts. This research aims to address these gaps by developing a novel framework to quantify productivity losses and duration extensions resulting from time-space conflicts, with a focus on assessing the varying impacts on different tasks. The primary objective of the study is to evaluate the effects of time-space conflicts on the productivity of individual work packages, considering their specific space occupancy, sensitivity levels, and conflict duration. Through the proposing of practical procedure, the study provides a more nuanced approach to calculating productivity loss and proposes an optimal degree of conflict overlap that can maximize overall project efficiency. Rather than promoting complete avoidance of overlap, the study explores the benefits of allowing controlled overlaps, offering a balanced approach to managing concurrent activities in limited spaces. By applying the proposed practical framework to real-world construction project data, this research ensures the practical relevance of its findings. The ability to predict productivity impacts and identify the optimum overlap level offers construction managers actionable insights for improving scheduling strategies, reducing project delays, and enhancing profitability. Ultimately, this study advances the field of construction management by offering a more accurate, adaptable, and practical approach for managing time-space conflicts, which can lead to improved project outcomes and enhance efficiency across the construction industry.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
