Abstract
The paper presents a new approach for obtained the sustainability of the construction works. In the technical literature there are a lot of models which evaluate the sustainability performance of the construction works with high applicability and very comprehensive. In many cases such models show some disadvantage: some models do not cover all three dimensions of the sustainability; all of them include a great number of criteria and many of them are difficult or impossible to quantify; they are focused manly on entire buildings and they can be applied with some difficulties on other types of construction works and activities. The first step to avoid such disadvantages was by proposal a so called specific model with some advantages: high degree of utilization includes only quantitative parameters, covers the three dimensions of sustainability. The second step is presented in this paper by a new approach which takes into account the price of each parameter and finally, the sustainability cost is established. The application of new model is presented on three different construction works. Using of the new approach some advantages are obtained: such calculation is easy understandably by specialists; by using the correction of the mechanical characteristics the most sustainable solution is obtained: costs of main parameters where taken from Romanian practice, but for different zones and countries, such costs will have to be used.
