Predictive cost modelling: Investigation utilising a qualitatively biased research methodology

Predictive cost modelling research has developed in the context of the traditional separation of design and construction activities of the building procurement process. This division is often considered an obstacle to the development of improved predictive cost modelling techniques, owing to the exclusion of the contractor's expertise from the design process. Recent shifts in procurement strategies, resulting in greater contractor involvement in the design stage of construction projects, provide fresh opportunities to investigate this perceived panacea. This paper reports upon research currently in progress into predictive cost modelling techniques utilised by design and construct contractors. In particular, the design and implementation of a predominantly qualitative research methodology, supplemented by quantitative techniques, is examined and postulated as the most appropriate medium for addressing the objectives of the research. Within this context, a theoretical resource based predictive cost modelling technique is developed. The model is subsequently tested utilising case-studies analysis. Preliminary results indicate a "fitness for purpose" of the methodology in the context of the research, although drawbacks are identified.
