For many construction projects, It is common for the customer to pay an incentive to the contractor for
finishing the project in a shorter length of time. In contrast, the contractor pays delay penalties if the project is delayed.
Goldratt 1997 suggested critical chain project management method (CCPM) as an attempt for minimizing project
duration. Goldratt approach and related buffer sizing approaches result in different values of project buffer and feeding
buffer which do not satisfy construction projects circumstances. The proposed model uses multiple shifts and discrete
relationship between activity time and cost to be solved by integer programming to express real-life construction
projects, optimize project duration with minimum cost and overcome CCPM such as Student's Syndrome, Parkinson's
Law and Multi-tasking. A simplified representation of a small example project is formulated to represent this model.
Application to a Cable Stayed Bridge is included. Final solution shows that this method is simple and can be applicable
for construction of mega projects to generate a shorter time at low cost.
