Megaprojects and Risk. An Anatomy of Ambition

Contractor selection is one of the main activities of clients. Without a proper and accurate method for selecting the most appropriate contractor, the performance of the project will be affected. The multi-criteria decisionmaking (MCDM) is suggested to be a viable method for contractor selection. The analytic hierarchy process (AHP) has been used as a tool for MCDM. However, AHP can only be employed in hierarchical decision
models. For complicated decision problems, the analytic network process (ANP) is highly recommended since ANP allows interdependent influences specified in the model. An example is demonstrated to illustrate how this method is conducted, including the formation of supermatrix and the limit matrix.

Contractor selection using the analytic network process

The Delphi method has been used as a main research method by a growing number of researchers in the Construction Engineering and Management (CEM) field in the past two decades. Although a number of studies are available on the use of Delphi, few researchers fully examine the potential of the Delphi method in the combined use of statistical techniques, which is an inevitable trend for future Delphi research. This paper aims to review the combined use of Delphi and other quantitative methods in the CEM field based on a structured literature review of 88 relevant papers. All of the 88 papers are systematically identified from ten well-known peer-reviewed CEM journals published in the period of 1990–2012. Topic coverage, application requirements, and statistical techniques in the 88 Delphi papers are reviewed. The mix use of the Delphi method with three advanced modelling methods, such as Fuzzy sets, Analytical Hierarchy Process, and Analytical Network Process is also examined. These review results pr...

This paper presents a multicriteria decision-making approach to evaluate contractor candidates in the open competition of construction project procurement by means of a knowledge-framed analytic network process (KANP), which embeds a construction knowledge framework into a formal analytic network process procedure. An applied KANP model named KANP.BID is set up and used in an experimental case study. The paper concludes that the KANP.BID model is a viable and capable tool for selecting the most appropriate tender alternative under criteria of sustainable construction. It is expected that the proposed KANP.BID model can attract interest from both practitioners and researchers in terms of further research and development.

Knowledge-driven ANP approach to vendors evaluation for sustainable construction

Purpose – The purpose of this paper is to explore the ability of “adaptable buildings” to respond to future potential built environment changes in sustainable way. Design/methodology/approach – A detailed literature review and a case study were undertaken to identify the life cycle changes of typical buildings over a period of more than 100 years. In total, 12 semi-structured interviews were conducted among construction industry professionals to identify how adaptable buildings enhance sustainability within the built environment. Case study data were analysed through a Morphological Analysis, and the interview data were analysed through discourse analysis. Findings – Out of the many adaptable features, the results revealed “change of use” as the dominant trend within the buildings of the selected urban cluster. More than 60 per cent of buildings have changed their original use during their life cycle. Around 10 per cent of them have changed their use frequently (every six year) during the last 20 years th...

Adaptable buildings for sustainable built environment

Employee turnover affects performance and competitiveness of companies. Traditional voluntary employee turnover models attempting to predict voluntary turnover are based on job satisfaction. A recent model that breaks away from this tradition is the unfolding model of voluntary employee turnover (UMVT) which takes account of additional factors such as labour market forces, economy and habit. UMVT has been tested in various industries. However, in the construction sector UMVT is tested for the first time in this study. A convenience sample of 320 construction professionals was taken from the Global Construction Consultants, Davis Langdon. The sample provided useable online survey data from 104 respondents who had voluntarily left their previous employers in the last four years. The results reveal that UMVT’s ability to interpret voluntary employee turnover among construction professionals was weak. In contrast to previous studies of UMVT, a significant number of respondents (80.8%) followed paths other tha...
