An analysis of contract cost phasing on engineering and construction projects

Abstract

The development and implementation of engineering and construction projects for new manufacturing facilities in the oil, gas, and petrochemical industry is largely contracted out. Progress and cost control by the owner is an intrinsic part of these projects. The results of an empirical analysis of payment and progress schedules for different contract types are presented, indicating a practice of advance payments on lump sum/fixed price contracts. The Value of Work Done concept and a normalized approximation function for progress control are discussed. The results provide guidance for progress management and contract cost phasing on engineering and construction projects. Copyright © Institute of Industrial Engineers.
