Determining the duration of construction projects is one of the important issues in project management and is a key factor affecting resource planning, contractual commitments, execution costs, and the timely commissioning of projects. In many projects, the contract duration is determined based on expert experience, similar projects, and professional judgment, which may result in discrepancies between the estimated and actual project durations. The present study aims to determine and model a time overhead factor for adjusting the baseline duration of construction projects. To this end, data from 57 construction projects implemented within the framework of the country's technical and executive system were collected, and the baseline duration of each project was determined based on the method proposed in a previous study. Subsequently, the time overhead factor for the studied projects was calculated using the ratio of the actual project duration to the baseline duration, and the factors affecting variations in this factor were investigated. In the next stage, data-driven methods and the algorithms employed in the study were used to model the relationship between the influencing factors and the time overhead factor, and the performance of the model was evaluated using statistical indicators.
