The Iranian construction industry is facing several problems including low productivity and immense housing scarcity. It is generally believed that industrialisation and offsite manufacturing can increase the productivity of the Iranian housing industry. Yet, one of the major issues of the Iranian construction industry is defective management during design and construction processes which has considerably increased the risks of offsite construction in Iran. BIM could theoretically address these issues thanks to its potential advantages such as improved efficiency, productivity, and quality. As one of the key stakeholders, architects have a major role in the current situation of the Iranian construction industry. A questionnaire survey was conducted in architectural SMEs to study the normal practices of architects during design and construction processes on site. Frequent design changes and defective communication between stakeholders were identified as the major issues. The results reveal that BIM in general and integrated design in particular could effectively address the aforementioned issues mitigating the risks of offsite construction in Iran.

Rework can bring negative effect to construction project. This research aims to identify the importance level of factors causing reworks in structural, finishing, and mechanical, electrical and plumbing (MEP) works by a way of importance performance analysis (IPA). In order to reach this objective, the research evaluates the degree of occurrence the factors in each type of works and analyzes the level of difficulty in preventing the occurrence of the factors. The results are based on questionnaire survey, involving general and MEP contractors in Surabaya. Design related factors are the most frequent and most difficult to prevent in structural and finishing works. In MEP works, the most frequent factors are tight construction duration and unclear instructions from owner and designer; whilst insufficient owner’s capital is the most difficult to prevent. The research finds two factors that have high importance level, i.e. design changes and insufficient detail drawings.

Construction industry like other industries is subject to risks due to the unique and complexity of the construction industries. It shows the risk exposure at highest level during the tendering process. The objective of this paper is to evaluate risk variable on contractor’s tender figure in Malaysia. To achieve the objective, questionnaire survey was conducted on G7 contractor in Malaysia. A total of 120 usable postal questionnaires was received. The findings have shown quality expectation, price inflation of construction materials, the risk involved in the project and financial capability of the client are most significant factors to be considered by contractors when estimating the pricing risks. The study recommended that competent contractors should be allowed to tender project as to see the risk variable inherent during tendering process that will affect project performance.

Construction practitioners recognise that rework is undesirable due to the detrimental effects. While rework literature has examined rework causation factors in construction projects, the problem continues to plague the industry resulting in poor delivery performance. To better understand this phenomenon and given the scarcity of Malaysian-based rework study, a questionnaire survey involving 130 Malaysian construction practitioners (consultants, contractors and clients) were undertaken to obtain feedback about nature, implications, causes and solutions for rework. Data were analysed using descriptive statistical techniques to prioritise the variables studied. From the analyses, rework is a causal factor for delays and cost overruns, higher wastage and productivity inhibitor. The findings revealed the leading causes of rework are poor quality management, improper planning, lack of communication, design changes and poor subcontractor management. Some practical rework minimisation approaches are also suggested to better manage and prevent rework towards enhanced project performance.

Decision Making Behavior

Based on the theory of consumer behavior, this paper analyzes the current situation of tourism shopping market in Kunming, and analyzes the decision-making behavior of tourists shopping in Kunming with the questionnaire survey, and clarifies the influencing factors of the decision-making behavior of visitors to Kunming. In the future, the influencing factors of Kunming tourists' shopping decision-making behavior are combined with the current situation of Kunming's tourism shopping market. The problems of cheating-induced shopping, the high price of shopping products, the low level of tourism shopping experience and the imperfect after-sales service are analyzed. Finally, the corresponding countermeasures and suggestions are proposed from four aspects: rectifying the tourism shopping market, establishing a sound price supervision mechanism, strengthening the tourism shopping experience, and improving after-sales service.

Causes Of Delays

The problem of delay in construction industry is a regular phenomenon worldwide, and construction industry of Pakistan has no exception, particularly in highways projects. Delay can be described as the extension of time to complete the construction project. The aim of this paper is to identify main causes of delays in highway projects of Pakistan, and to determine mitigating measures for the identified causes. The research method of this study is based on literature review, questionnaire survey and semi structured interview. From in-depth literature review, twenty-six common causes of delay were found. A questionnaire survey was carried out among construction professionals of highway projects. The causes of delay in highways projects were ranked referring to their Mean values. A semi structured interview was carried out to determine mitigation measures for the top ten causes of delays. The data gathered from questionnaire survey was analyzed using SPSS (Statistical Package for the Social Sciences) while, data collected through semi structured interviews was analyzed using Nvivo software. The findings of this study are expected to be useful for construction parties, to mitigate the delays in highway construction projects of Pakistan.

Hall's conceptualisation of professionalism, among other studies, was considered the most representative modern concept; his scale has been studied widely. This study aimed to evaluate empirically the Snizek modified version of Hall's Professionalism Scale for building professionals. The scale was tested in a cross-section of 510 qualified building professionals selected from four countries. Using a cross-national electronic questionnaire survey, a series of statistical analyses were conducted to evaluate the Snizek's modification. Analysis suggested that data for scale validation are consistent in confirming it is a five-factor scale; however, the scale should be subjected to a further refinement before it can be used in research.
