Constructibility Criteria - A Systemic approach

The construction sector suffers from low productivity, poor adherence to costs and deadlines, and poor quality .

There are many reasons for this, and it is difficult to pinpoint a single cause. Some believe that it is due to a political will on the part of project owners to underestimate their projects in order to make them more easily accepted , others that it is the type of contract that is at the root of these excesses or even that it is due to a lack of technical mastery of the risks and uncertainties inherent in these types of projects .

Our view is that the reasons for such excesses are more a combination of factors than a single cause, and that the above-mentioned reasons are among others. Indeed, the point of view adopted in this article stems from the observation that construction projects are becoming increasingly complex or, at the very least, that their complexity is being poorly managed with inadequate resources. Our aim is to contribute to the development of the profession through better management of the costs, deadlines and quality of construction projects.

To this end, we have turned our attention to Systems Engineering, one of whose objectives is to manage complexity. These methods, which are essentially used in other industries, need to be adapted for application to the construction...
