A new approach to cost forecasting

At 3f, we are inspired by the way of thinking of engineers, as, for example, Gustave EIFFEL. In order to build more and more innovating structures, he permanently tried to extract from the results of his experiences the laws that govern his type of construction.

He found concepts, which were not well known at his time, of materials yield strength and of metallic constructions. He was then able to concieve his tower, without any mistake on the costs, the schedule and the reliability.
