Abstract
Temporary structures are essential to support various activities of a construction project. Proper utilization of temporary structures can have a significant influence on critical aspects of the project such as cost, productivity, and safety. However, a process of planning temporary structures still relies on labor-intensive and error-prone efforts based on implicit knowledge of workers. Moreover, temporary structures are planned without detailed spatiotemporal analysis of their implications and systemized approach to safety. This tendency may yield the inefficient employment of temporary structures and unsafe job sites. Lack of systemized approach for identifying hazards related to the temporary structure would result in not only an economic loss but also fatalities and injuries. This paper introduces a building information model- (BIM-) based decision support system that provides safety plans for temporary structures considering their costs and durations. Focusing on scaffolding, the system automatically generates multiple scaffolding plans and quantitatively evaluates them regarding safety, cost, and duration. By analyzing project-specific spatiotemporal information to identify relevant hazards and variations of cost and duration, a specific plan for utilizing scaffolds, which is the most appropriate regarding safety, cost, and duration, is selected among the generated plans. The developed system was implemented using a BIM software tool and validated with an in-depth case study on a real-world construction project. This can be utilized as a decision-support system that enables the users to develop a plan with minimized safety hazards related to scaffolding while considering workflow, cost, and duration at the same time.

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
