Abstract

The calculations of life cycle costs (LCC) and whole life costs (WLC) are important tools in the life cycle of a project. The aim of this research is to examine life cycle costing, whole life costing, and the possible advantages and disadvantages to their introduction and use. A qualitative methodology encompassing an in-depth literature review, interviews, and qualitative analysis using mind mapping software, this research is important as it can add to the industry's understanding of the design process. It highlights reasons for the success or failure of a construction project, in terms of sustainability at the design stage. Results indicate that the researched topics had many advantages but also had inherent disadvantages. It is found that the potential advantages outweighed disadvantages, but uptake within industry is still slow and that better promotion and their benefits to sustainability, the environment, society, and the industry are required.

Methodology

Three tiers of research were sequentially carried out for this paper; an in depth literature review, two semi structured interviews and a focus group were held with industry professionals and qualitative analysis. The information gathered through the literature review is enhanced by the gathering and interpretation of further results from the Qualitative analysis. The semi structured format was chosen as it was felt it was the best way to elicit as much relevant information as possible as one question can lead to another and gives the interviewee an opportunity to provide as much information as possible and freely express their thoughts and opinions. All interviews were anonymous and nothing would be included to identify practice or employee. Results from the interviews / focus group were then inputted into qualitative mapping software to be analysed. This allows the unstructured information gathered to be mapped, structured and documented in a way that shows relationships between clusters in the data. The software used is Decision Explorer by Banxia
