Approaching projects from a global cost perspective and dynamic is a growing approach in France and elsewhere.
The overall cost in construction is the sum of the investment, operation, maintenance and end-of-life costs of a building over a specific period.
Since the 1980s, this notion has encountered quite a few difficulties in its development. Some see it as an aid to arbitration, the calculation of which remains to be clarified, and above all a dynamic and an objective to build better; and others denounce the extreme complexity, even the uselessness, of a calculation which can only remain approximate, subject to variations.
According to CEREMA: “in a context marked by strong ambitions in terms of energy transition, as well as by a budgetary constraint affecting investment capacities, the technical-economic optimization of projects is now essential ” . For this, working on the overall cost approach appears to be an essential decision-making tool in construction projects, for public and private project management. It promotes energy efficiency and optimization of the carbon footprint from a perspective of sustainable development and quality improvement.
Today, project owners and elected officials in particular feel more than ever the need to know what a building will really cost them until its end of life. It is with this in mind that QUOTEX , a distribution company for pre-sales solutions for the costing of construction projects, in its policy of responding to customer needs turns to this overall cost reasoning. It is a question for us of collecting the issues and needs in order to set up a calculation methodology with different scenarios available in our Quickdevis (QDV) pricing software.
To help us with this survey, we kindly ask you to complete this questionnaire which will only take two minutes of your time.
