The desirability to deliver construction projects within the schedule or more even longer ahead of it is questioned. Nevertheless, most of the construction projects are delivered behind of schedule and even exceed it to more than conceived. So the necessity to find new methods, processes and techniques to challenge the delivery time of the construction projects becomes more than a simple requirement. Overlapping the sequential activities is one way to reduce the delivery time of the project. The manufacturing industry has predicted this fact and established concurrent engineering principles. This paper will inspect the initiative done to involve concurrent engineering principles in the Norwegian oil and gas projects then in the construction projects. It will investigate the work done in the theory, and practice in construction projects compared to the oil and gas projects that have been conducted by a construction firm in Norway.
