Evaluating the cost of disruption in retrofit office building projects

Purpose of this paper: The purpose of this paper is to evaluate the cost of disruption in office retrofit building projects. Design/methodology/approach: This work adopts a positivist approach and evaluates the cost of disruption based on the estimated level of disruptiveness of retrofit technologies. Different Building configuration Permutations (BCPs) in two recent case study projects – A and B, are developed. The cost of disruption in the projects are estimated as a proportion of the staffing and business operating cost in respective organisations. Findings and value: It was found that the average cost of disruption in Project A can lead to an additional cost of 2 – 12%, relative to the initial capital cost; and the average cost of disruption in Project B can lead to up to 0.2 –1.5%, relative of the initial capital cost.
