Research Methods for Construction

De
320 pages
This is one of the few books to provide guidance on research formulation, methodologies, and methods specifically for construction students.

The third edition has been updated throughout and extended in scope to cover many areas of concern in quantitative and qualitative research, including research ethics.

Three main sections - producing a proposal; executing the research; and reporting the results - discuss the key issues in research and examine the primary approaches, both qualitative and quantitative. The methods adopted for scientific and engineering experiments, model building and simulations are discussed, as well as those employed for research into management, social and economic issues.

The authors examine the requirements for data and analysis, including the important statistical considerations and a range of qualitative techniques that enable construction researchers to appreciate what needs to be evaluated in devising how research may be carried out effectively and efficiently. Research Methods in Construction will help you instil rigour into your problem-solving, and your reports and publications. It will be of value to construction, surveying, architecture and civil engineering students undertaking research, whether for bachelors and masters degree dissertations, or for masters and doctoral research degree theses.
