Every construction project evolves through a series of stages, originating from the preliminary study followed by several design stages and finally the implementation of the design with the actual construction. Cost and material quantities estimates are produced throughout the life of a construction project and are used for different purposes depending on the available information and their expected accuracy. An easy to apply cost pre-estimating and material quantities formulation is proposed for overpass bridges based on the processing of data from fifty seven existing bridges in order to assist stakeholders in the bridge construction industry when choosing the most cost effective design solution in order to reduce the risk of failure and loss of funding.
