Six Critical Success Factors (CSFs) for the implementation of a Project Quality Management System (PQMS) have been determined according to previous surveys. The PQMS’s CSFs include client’s commitment, integration of quality plan, measurement and improvement, education and training, teamwork and communication, and use of information and communication technology (ICT). However, implementation of PQMS is still considered not encouraging when a number of issues such as lack of commitment from stakeholders, lack of teamwork and communication among the parties involved, lack of training and learning, uncertainty in the plans qualities involved, and voluminous of documentations still occur. These problems are augmented by lack of knowledge and skills as well as the absence of a comprehensive guide to implement PQMS. Therefore, to address these problems, a set of best practices to implement PQMS’s CSF was established through the formulation of three related objectives: 1) Determine the practices for each of PQMS’s CSF; 2) Determine the project success criteria that have a positive impact with the implementation of PQMS; and 3) Study the relationship between the practices for PQMS’s CSF and criteria for project success to form a set of best practices. The study was conducted using two methods, which was an interview with an expert to verify the elements formulated in the questionnaire and distribution of the questionnaire. Initially, 31 practices and 10 project success criteria were identified through literature review followed by interviews conducted with experts. An addition of two practices were included in the list making it 33 practices but the project success criteria remain the same. Then, the questionnaires were distributed to 500 Grade 7 contractors registered with the Construction Industry Development Board (CIDB) in Peninsular Malaysia. However, 275 were returned and only 223 were completed and accepted to analyze for this research. Then, the data were analyzed using descriptive analysis and relative importance index (RII) to achieve objectives 1 and 2, and SEM-PLS was used to achieve objective 3. The findings of the study showed that 28 of 33 practices have been identified to implement PQMS’s CSF. In the meantime, only nine of ten criteria had positive impacts with the implementation of PQMS. Thus, these findings have shown that 25 of 33 practices were determined as best practices to successful implement PQMS’s CSF in construction. These best practices can be viewed as a new contribution to the body of knowledge by being the basis as well as reference for academics and industry to ensure that construction process will be efficient in the future

Exploring competencies for green building project manager

Sustainability concept has grown in recognition and importance since the last 10 to 15 years and the issues of achieving sustainability, climate change as well as environmental protection have been addressed by the construction players. While many studies have examined the competency of project managers, there is little attention given for green building construction. Therefore, this study aims at identifying a list of competencies for green building project manager. Through literature review, a total of 49 competencies have been identified from previous studies and this search is limited with the year of published article ranging from 2000 to 2015 using Google Scholar, which were then analysed using content analysis. This study can help in creating further knowledge and skills for project managers to be more relevant and effectively execute sustainable projects

An overview of the management commitment to safety elements for mitigating accidents in the construction industry

Due to the importance of management commitment to safety for influencing workplace safety performance, this paper aims to investigate the current literatures, prepare a compilation and gap related to the demonstrated management commitment to safety and its elements that mitigate workplace accident in the construction industry through a clearly structural methodological approach. Hundreds of articles were explored using article keyword identified from the literature reviews. The articles abstract were reviewed repeatedly resulted in 61 relevant articles for compilation of management safety commitment including related articles from other industry. The elements of management commitment to safety were identified using content analysis and inductive coding technique. Apart from that, critical analysis was conducted to identify gaps in the literatures. From the content analysis, a total of 19 elements reflected the management commitments to safety were identified. Additionally, it was found that lots of studies have been done on safety commitment in specific aspect but more comprehensive research regarding cause and effect of actual safety commitment is suggested

Extraction and characterization of lignin from oil palm biomass via ionic liquid dissolution and non-toxic aluminium potassium sulfate dodecahydrate precipitation processes

The objective of this study is to extract and characterize lignin from oil palm biomass (OPB) by dissolution in 1-butyl-3-methylimidazolium chloride ([bmim][Cl]), followed by the lignin extraction through the CO2 gas purging prior to addition of aluminum potassium sulfate dodecahydrate (AlK(SO4)2·12H2O). The lignin yield, YL (%wt.) was found to be dependent of the types of OPB observed for all precipitation methods used. The lignin recovery, RL (%wt.) obtained from CO2-AlK(SO4)2·12H2O precipitation was, however dependent on the types of OPB, which contradicted to that of the acidified H2SO4 and HCl solutions of pH 0.7 and 2 precipitations. Only about 54% of lignin was recovered from the OPB. The FTIR results indicate that the monodispersed lignin was successfully extracted from the OPT, OPF and OPEFB having a molecular weight (MW) of 1331, 1263 and 1473g/mol, and degradation temperature of 215, 207.5 and 272°C, respectivel
