Repertory Grid Methodology to Research Tacit Knowledge in Construction

Abstract

Abstract Quality and buildability are important issues in construction, and both emerge at the earliest stages of design. However, neither are well-defined concepts. Our premise is that behaviour, values and culture impact on quality and buildability in the design stage, but these are also vulnerable to precise definition and difficult to investigate within a typical hypothesis-driven positivist approach. A better method may lie in a theory of personal constructs or ‘constructivism’ which takes the human experience as a whole. Qualitative research methods and data collection techniques are critically reviewed to assess those methods best fitted for purpose in approaching the research problem. Personal Construct Psychology (PCP), using repertory grids emerges as a suitable candidate and is applied in two pilot studies in Australia and Singapore. Preliminary results show the appropriateness of the approach for engaging in buildability studies.
