N2 - Fast-track construction projects have become more popular in recent years in response to growing industry demand. By allowing a downstream activity to start with incomplete information from upstream activities, fast-tracking allows for shortening the project duration at the expense of an increased likelihood of rework. This leaves practitioners with the challenge of determining the optimal fast-tracking strategy, which meets project schedule requirements and does not cause excessive amounts of rework. This paper presents an optimization based model that serves as a decision support tool in scheduling fast-track construction projects. The model takes into consideration information exchange between upstream and downstream activities. The objective function of the model is to maximize the net benefits from fast-tracking. Rework time and cost are deduced from the literature on rework in construction projects. The model is illustrated on a small scale case study, which was analyzed under various scenarios. The paper concludes with a discussion of the applicability of the model on complex construction projects.
