The bid/no bid decision requires an understanding of a company's assessment in relation to factors affecting the decision. Different companies might have different assessment values. The aim is to investigate how bid/no bid decisions are influenced by different characteristics of contractors. Various factors are identified and then analysed in order to investigate their influence and relative significance. A questionnaire survey was used to identify and rank the factors affecting the bidding decision and then analyse them in terms of differences between the returned responses with respect to the differing respondent characteristics. The findings have established the ranking order of the factors affecting the bid/no bid decision and identified their weights of importance. In addition, the influence of these characteristics upon the different weights of importance given by the survey respondents is found to be statistically significant. The most influential characteristics that affected their assessment of the weight of importance are contractor size, classification status of the contractor and the main client type. Different contractors' characteristics should be reflected in the way that the bid/no bid decisions are modelled. Also, the data collected should be categorized with regards to contractors' characteristics before starting the data analysis and modelling processes.Bid/no bid decision, decision making, project selection,

Decision-making and subjective evaluation are two important aspects that characterizes the involvement of an organization in tender process. Moreover, selection of the right project to bid for is a principal feature of business success. The study aims to investigate the behavioral differences of Saudi construction contractors toward internal and external factors based on the process of modelling the bidding decisions. A quantitative research design is used to investigate the behavioral differences of 97 contractors recruited from construction industry of Saudi Arabia. A questionnaire was distributed among the respondents that would help in identifying the significant level of factors affecting the bid or no bid decision. The impact of internal and external factors on the bidding decisions was evaluated using one-way ANOVA analysis. The results have shown a significant and positive effect of internal and external factors on the bid or no bid decision; including job start time, work capital requirement, availability of qualified human resources, bidding methods, bidding document price, project supervision procedure and etc. The study has helped in establishing a better understanding toward the behavioral differences of contractors with respect to the bidding decisions.

The potential of Industry 4.0 digitization practices to improve sustainability and enhance overall project performance has garnered significant attention in the construction industry. Nonetheless, there is a necessity for empirical investigations that delve into the particular factors and constructs that contribute to this achievement. This research aims to address the existing gap in the literature by examining the favorable consequences of Industry 4.0 digitalization techniques in the context of sustainable construction management. The research utilized a mixed-methods methodology, integrating exploratory factor analysis (EFA) and structural equation modeling (SEM), to examine survey data obtained from the construction sector in China. The survey questionnaire comprised constructs that pertained to sustainability, technology, design, functional aspects, resource management, and managerial efficiency. The concept of sustainability has been identified as the most significant factor in shaping sustainable construction practices. The findings presented herein contribute to the theoretical comprehension of the determinants that impact the execution of Industry 4.0 digitalization methodologies within the construction sector. The interrelated constructs that have been identified provide valuable insights for practitioners and policymakers seeking to utilize Industry 4.0 practices to achieve sustainability, enhance technology adoption, optimize design processes, streamline functional aspects, improve resource utilization, and increase managerial efficiency. Implementing these strategies can enhance project success and ensure long-term sustainability in the construction industry. This research adds to the expanding pool of information regarding the factors that lead to success in Industry 4.0 digitization practices within sustainable construction management.

Introduction Construction companies hold great significance in Saudi Arabia due to new developments taking place in the region. A project automatically turns out better if it has been selected based on the level of expertise and resources available to the construction company and vice versa. Purpose The study aims to investigate the importance of project selection by the contractors within the Saudi construction industry. Methodology The study has employed a quantitative research design to conduct a survey through the administration of questionnaire. A total of 46 employees from construction companies were selected. A questionnaire was distributed among maintenance contractors, contractors, and construction contractors. Findings The findings have shown that mostly organizations were unclassified or classified under the fifth category (projects valuing AED10,000,000 or lesser) (34.8%). Most of the respondents (94.4%) agreed that consideration of the project selection is important. Moreover, there is a positive correlation between the level of importance given to the project selection and the organizational size of the respondents. Success factors play an important role in the project selection phase. Practical implications Careful project selection is the first step toward the success of the construction company, so it needs to be carried out carefully.

Background:The construction companies need to maintain their success levels to survive in the competitive business environment. The concept of just-in-time plays a significant role to reduce the costs and fulfill the needs of valued customers. Objective:The study aims to evaluate the role of honest customer services that are provided to the construction companies in Saudi Arabia. Methods:The study has used a case study approach to analyze the role of on-time and honest customer services in the success of small construction companies. Interviews were conducted to gather details and characteristics of the associated company. It mainly focused on the interactions and behaviors of participants, rather than calculations. Results:The results have provided a great understanding of the success of construction companies based on success factors. The organizational culture, delayed schedule, required quantity, and just-in-time purchasing are amongst the exceptional and highly effective factors on just-in-time delivery and customer experience. Moreover, organizing and planning were considered to be important factors contributing to company success. Conclusion:There is a strong association between the delivery of honest customer services and the success of construction companies in Saudi Arabia .
