A new cost control model and indicators to measure productivity on building sites

Abstract

An accurate estimation of project costs is always a great challenge for a construction company, particularly when there is a commitment with the owner to achieve a project at a given price. It is thus essential to develop technical and logistic solutions (TLS) ensuring a good organisation and improving the productivity. These improvements are not yet well assessed because relevant models are not available at the right time. This paper presents a new approach for assessing productivity by using an analytical cost model and indicators widely used to measure the site productivity. A case study is described to validate the cost and indicator model. They can be used in a decision making process consisting of a comparative study of different TLS in order to select, in a predicted term, the TLS ensuring the best productivity. A decision support system for generating different alternatives to be compared is currently under development.
