Abstract
For any building project, the project management triangle QCT (Quality, Cost, Time) are decisive in the decision-making process. Indeed, better, faster and cheaper remain very important goals in the design of new industrial products in a competitive environment. In this paper, we propose a reference framework to formalize the quality criterion that characterizes a building made during a project. A quality measurement is then defined based on the performance levels of the functions actually provided by a building and the requirements originally formulated by its owner. In addition, a modeling of the building production process is proposed to observe the effects of technical or managerial choices on the expected quality of a new or renovated building. Finally, a representation of the level of performance of each building technical attribute over its life cycle is proposed in order to represent the performance recovery allowed by a renovation operation as a resilience process. In the end of this paper, a section is dedicated to a computational experiment for illustrating the theoretical approach.
Highlights
Quality is commonly expected all along the phases of a building life cycle
The decision criterion "Quality" commonly mentioned from the operational and academic point of view on building construction projects has been quantified in this paper
From this modeling comes the formalization of a transfer function linking the likely performance level of a technical attribute to a set of parameters including the amount of resource allocated, the complexity of the constructive processes, and the level of skill of the manufacturer
Summary
Quality is commonly expected all along the phases of a building life cycle. Firstly, during a construction project, the quality, the cost and the time of execution, are the three criteria used to make decision between the various technical options. Given the fact that the building simultaneously provides several functions that can be characterized by performance levels of various dimensions, it becomes relevant to propose a global quality measurement system based on the attributes of these functions and on the requirements set out in the contracted specifications of the project. (i) The definition of a performance measurement depending on a building technical attribute (θi) in order to obtain an objective index taking into account two functions. A density function ρθ(.) modeling the real values historically obtained for the implementation of a given construction process This approach is seen as the assessment of a builder ability to deliver a building that meets performance requirements. For the rest of this paper, we adopt the notation θ instead of θi for the sake of simplicity of writing
