Conceptual cost estimates are critical inputs for owners' decision-making in the early planning stages of construction projects. However, a recurrent problem associated with conceptual estimating is how to assess the quality of the estimates, i.e. the expected accuracy and reliability of cost figures given the uncertainty and risk that every project will face during its development. One of the approaches used to assess the quality of an estimate is the application of expertise and experience. This paper examines the problem of the quality of conceptual estimating, proposes a model of this problem based on existing knowledge and shows how the model was used to develop an assessment system. Through the use of expert knowledge, it is possible to get an appropriate initial assessment of the expected accuracy and reliability of an estimate which should be later complemented with historical and empirical information. |
