Abstract
Time overrun in construction projects is a very serious issue in developed countries. The main object of this research is to find the main causes of time overrun in the construction of building project and its possible mitigation measures. Quantitative approach was adopted in this research to achieve object and RIW (relative importance weight) approach was used for collecting data. Financial issues faced by the contractor, contractor’s inexperience, weather impacts, late delivery of material, mistakes in design, shortage of skilled labor, incompetent subcontractor and mistakes in time estimation were identified as main causes of time overrun in construction projects and possible mitigation measures were also proposed from experts. This research will help in giving awareness to stakeholders to narrow down the factors of time overrun in construction projects in Pakistan.
Highlights

Time overrun can result in many negative impacts on the construction project like budget overrun, low productivity, contract expiration, work acceleration resulting in bad quality, and disputes among construction stakeholders [3]
According to [8] only 47% of projects were completed within approved time frame, around 38% of construction projects were behind time frame and 15% of construction projects were completed ahead of time in Indonesia

It is observed that many construction projects face the issue of time overrun worldwide both in developing and developed countries like USA or UK [4, 5]. Authors in [6] stated that more than 40% of projects in construction industry experiences time overrun. Time overrun is one of the most severe problems in the construction industry of Pakistan [9, 10]. Author in [11] reported that the majority of the Pakistan construction projects were 11% to 30% below their approved time fame.
