To ensure the success of a construction project, the economic efficiency of projects today is directly linked to the architecture, the floor plan and facade design as well as the choice of structural systems and building services concepts. This is why we support projects in terms of cost efficiency as early as SIA phase 22, meaning during the feasibility study or preliminary project phase. Thanks to the benchmarks and the database of completed construction projects, we are able to produce precise cost forecasts in the early phases. By means of construction economics considerations, the projects are managed in such a way that the project completion will be successful.
