C.; Chan, Daniel W. M.; Chiang, Yat-hung; Yang, Huan<br/><br/>Abstract: This paper attempts to incorporate both leading and lagging KPIs and apply the reliability interval method (RIM) to formulate a benchmarking model to assess project success in Hong Kong. A list of leading and lagging KPIs was complied based on a comprehensive literature review. This list of KPIs was used to develop a survey questionnaire and RIM was subsequently used to analyze the survey results and determine the relative importance and rankings of various leading and lagging KPIs. The results reveal that the top 10 KPIs to evaluate the success of construction projects in Hong Kong (in descending order) were (1) safety performance, (2) cost performance, (3) time performance, (4) quality performance, (5) client’s satisfaction, (6) effectiveness of communication, (7) end user’s satisfaction, (8) effectiveness of planning, (9) functionality, and (10) environmental performance. Finally, a composite performance index (CPI) was derived by means of RIM to provide a comprehensive assessment of construction project success in Hong Kong. Different construction projects can now be assessed on the same basis for benchmarking and project monitoring purposes.<br/><br/>Description: DOI: 10.1061/(ASCE)CO.1943-7862.0000622 http://hdl.handle.net/10397/5631 Title: Investigation of barriers to entry into the design-build market in the People’s Republic of China<br/><br/>Authors: Xia, Bo; Chan, Albert P. C.<br/><br/>Abstract: Although the design-build (DB) system has been demonstrated to be an effective delivery method and has gained popularity worldwide, it has not gained the same popularity in the construction market of the People’s Republic of China (PRC). The objective of this study was to investigate the barriers to entry in the DB market. A total of 22 entry barriers were first identified through an open-ended questionnaire survey with 15 top construction professionals in the construction market of China. A broad questionnaire survey was further conducted to prioritize these entry barriers. Statistical analysis of responses shows that the most dominant barriers to entry into the DB market are lack of design expertise, lack of interest from owners, lack of suitable organization structure, lack of DB specialists, and lack of credit record system. Analysis of variance indicates that there is no difference of opinions among the respondent groups of academia, government departments, state-owned companies, and private companies, at the 5% significance level, on most of the barriers to entry. Finally, the underlying dimensions of barriers to entry in the DB market were investigated through factor analysis. The results indicate that there are six major underlying dimensions of entry barriers in DB market, including the competence of design-builders, difficulty in project procurement, characteristics of DB projects, lack of support from public sectors, the competence of DB owners, and the immaturity of DB market. These findings are useful for both potential and incumbent design-builders to understand and analyze the DB market in China.<br/><br/>Description: DOI: 10.1061/(ASCE)CO.1943-7862.0000387 http://hdl.handle.net/10397/5630 Title: Analysis of selection criteria for design-builders through the analysis of requests for proposal<br/><br/>Authors: Xia, Bo; Chan, Albert P. C.; Zuo, Jian; Molenaar, Keith<br/><br/>Abstract: Selecting an appropriate design-builder is critical to the success of design-build (DB) projects. The objective of this study is to identify selection criteria for design-builders and compare their relative importance by means of a robust content analysis of 94 requests for proposal (RFPs) for public DB projects. These DB projects had an aggregate contract value of over US$3.5 billion and were advertised between 2000 and 2010. This study summarized twenty-six selection criteria and classified them into ten categories, i.e., price, experience, technical approach, management approach, qualification, schedule, past performance, financial capability, responsiveness to the RFP, and legal status, in descending order of their relative importance. The results showed that although price still remains the most important selection category, its relative importance has declined significantly in the last decade. The categories of qualification, experience, and past performance, by contrast, have become more important to DB owners for selecting design-builders. Finally, it is found that the importance weighting of price in large projects is significantly higher than that in small projects. This study provides a useful reference for owners in selecting their preferred design-builders.<br/><br/>Description: DOI: 10.1061/(ASCE)ME.1943-5479.0000119 http://hdl.handle.net/10397/5629 Title: Determining safety climate factors in the repair, maintenance, minor alteration, and addition sector of Hong Kong<br/><br/>Authors: Hon, Ka Hung; Chan, Albert P. C.; Yam, Chi-ho Michael<br/><br/>Abstract: Accident record of the repair, maintenance, minor alteration, and addition (RMAA) sector has been alarmingly high; however, research in the RMAA sector remains limited. Unsafe behavior is considered one of the key causes of accidents. Thus, the organizational factors that influence individual safety behavior at work continue to be the focus of many studies. The safety climate, which reflects the true priority of safety in an organization, has drawn much attention. Safety climate measurement helps to identify areas for safety improvement. The current study aims to identify safety climate factors in the RMAA sector. A questionnaire survey was conducted in the RMAA sector in Hong Kong. Data were randomly split into the calibration, and the validation samples. RMAA safety climate factors were determined by exploratory factor analysis on the calibration sample. Three safety climate factors of the RMAA works were identified: (F1) management commitment to OHS and employee involvement; (F2) applicability of safety rules and work practices; and (F3) responsibility for health and safety. Confirmatory factor analysis (CFA) was then conducted on the validation sample. The CFA model showed satisfactory goodness-of-fit, reliability, and validity. The suggested RMAA safety climate factors can be utilized by the construction industry practitioners in the developed economies to measure safety climate of their RMAA projects, thereby enhancing safety of RMAA works.<br/><br/>Description: DOI: 10.1061/(ASCE)CO.1943-7862.0000588
