Current State of Highway Projects Planning and Scheduling

Highway projects involve huge capital investments and prolonged durations. A number of researchers have developed various computer-based tools and techniques to help planners prepare plans and schedules based on their specific needs. CPM is the predominant scheduling method used in construction industry. However, its inability to efficiently plan and schedule repetitive projects such as highways has widely been recognized. Linear scheduling method on the other hand, was specifically designed and developed for repetitive projects. The aim of this paper is to study various planning and scheduling methods discussed in the literature and evaluate their suitability for highway projects. On the basis of literature study, location based planning utilizing linear scheduling method seems to be the most logical and efficient way of planning highway projects for various reasons discussed in the paper. It is however a new concept and therefore has limited use in practice. Current State of Highway Projects Planning and Scheduling
