“…This is achieved by computing the variance between contractual completion date and actual completion date, and multiplying that variance by the daily liquidated damage or incentives, as applicable. Indirect costs can be stipulated either as a per diem rate or as a percentage of direct costs, as described by Moselhi and Hassanein (2003).…”

Scheduling linear repetitive construction projects, such as highways and pipelines, poses unique challenges due to maintaining crew work continuity. An efficient method is presented, developed to accelerate the delivery of this class of projects so as to meet a specified deadline with least associated cost. The method is simple and ensures crew work continuity. An iterative approach is employed, where, in each iteration, the project schedule is analysed and an activity is identified as the controlling activity. A controlling activity is an activity that if accelerated, would reduce project duration at least additional cost. Upon its identification, the method selects an expediting strategy that would reduce project duration, and the project is rescheduled. Several expediting strategies are considered, including working overtime, double shifts and weekends. The method is implemented in a prototype software that operates in a Windows� environment, providing a user-friendly graphical interface. It has an open architecture, enabling the user to actively participate in tailoring the generated schedule to suit the requirements of the project at hand. The proposed method accounts for incentives and liquidated damages to aid users in identifying the most cost-efficient schedule. A relational database model is implemented in Microsoft Access� to store typical crews and their associated productivity, as well as their availability dates. A project, drawn from the literature, is analysed to demonstrate the basic features of the proposed method and highlight its capabilities.Repetitive construction, acceleration, crew productivity, time-cost trade-off,

“…Handa and Barcia [9] presented an integer dynamic programming model to optimize the project duration. Additional research has utilized dynamic programming in minimizing total cost or project duration by integrating cost, time, or heuristic rules (El-Rayes and Moselhi; Moselhi and El-Rayes; Senouci and El-din; Moselhi and Hassanien) [10][11][12][13].…”

“…Moreover, Russell and Caselton [7] extended the work of Selinger in developing a two-state variable, N-stage dynamic programming formulation that minimizes the duration of linear construction projects. Additional research has utilized dynamic programming in minimizing total cost or project duration by integrating cost, time categories, or heuristic rules [3,8,9,10].…”
