Estimation of project total cost and duration for housing projects in the U.K.

Abstract

There are a number of variables which act individually and in combination to influence project total cost and duration. The extent of the effect of these variables is dependent on the nature of the project. A project is defined in terms of its constituent variables. This paper is concerned with a variety of project definitions within the category of housing projects in the U.K. The most influential variables are examined and, in quantified terms, the extent of the relationship between these variables and project total cost and duration is determined. To this end, two separate models are developed and proposed for the estimation of project cost and duration. While the model for the latter encompasses the former as a variable, the model for the estimation of project cost is independent from project duration.
