Abstract

The present work is based on empirical data of a part of the Rolai-Rinjlai road construction project, in which raw material is available at different quarries providing different options to the contractor. Considering the project as a network, we used CPM technique in an attempt to obtain the critical path of the network and suggested the best approach for acquiring material and construction of road under the stated constraints. We used crashing to further reduce the project completion time. The solution suggested by us provide a much shorter completion time as compared to the actual time taken by the project. To this end, we use crashing not only to minimise time economically, but also to identify viable means that were earlier ignored by the contractor which resulted in a schedule that required time as well as cost less than that taken by for the initial CPM solution.
