Relationships between total construction cost and project strategic, site related and building definition variable

There is a paucity of recent literature on the influence of project strategic, site related and design related variables on the cost of construction. This paper seeks to redress this omission by presenting the results of an investigation into the influence of 41 independent variables on both construction cost and client cost. Data were collected from 286 construction projects in the United Kingdom and correlation and test for differences were used to determine the relationships that exist between the dependent and independent variables. The analysis both confirms the strong relationship between construction cost and client cost and between those two measures of cost and GIFA, and establishes other relationships which exist within the data, confirming many of the relationships that had been anticipated from the literature. It also established the ordinal sequence of several nominal variables. These data, therefore, can be confidently used to develop models of the total cost of construction.
