    Synergy in a contractor project team improves performance by integrating diverse knowledge and skills among team members, enabling the achievement of project objectives. However, according to a literature review, factors that enhance synergy among contractor project teams from the perspective of executives and practitioners have rarely been discovered, revealing a knowledge gap that needs to be filled. Therefore, the aim of this study was to identify a common structure of such factors for executives and practitioners. Data collection involved a questionnaire survey targeting large contractors in Bangkok, Thailand. Then, we compared the mean importance and rank order of synergy factors, examined differences and similarities in synergy factors between executive and practitioner perspectives using the Mann–Whitney U test, and applied confirmatory factor analysis (CFA) for the data analysis. The differences and similarities show that executives and practitioners have similar perspectives on synergy factors. The CFA results validate a factor structure that enhances synergy. This synergy factor structure for executives and practitioners can be divided into five groups, with their standardized regression weights in parentheses: coordination (0.94), organizational structure (0.92), motivation (0.80), leadership (0.75), and planning and policy (0.69). These findings contribute to the body of knowledge and the state of practice by offering a practical framework to assist executives and practitioners in contractor organizations in identifying common measures and resource allocation based on the regression weights of synergy factors. This can improve synergy among contractor project teams, potentially resulting in better performance.

    The selection and use of appropriate construction equipment contributes to operational efficiency and contractor competitive advantages. However, numerous factors are involved in the selection of suitable construction equipment. A review of the existing literature revealed a lack of research on the causal relationships between construction equipment selection factors and contractor competitive advantages. Therefore, this study attempted to identify the selection factors through a survey of contractors’ opinions on the levels of importance of the factors that are relevant to construction equipment selection and competitive advantages. The survey data were analyzed using Structural Equation Modeling (SEM). The results suggest the following six major selection factors and their respective weights of relative importance: compatibility with site characteristics (25%), services and maintenance (19%), costs (15%), safety and environmental effects (14%), ease of acquisition (14%), and technology and innovation (13%). These selection factors influence contractor competitive advantages in terms of financial stability, corporate image and reputation, bidding opportunity, and technical capacity, and their weights of relative importance are 31%, 25%, 22%, and 22%, respectively. The findings of this study shed light on the causal relationships between the selection of appropriate construction equipment and contractor competitive advantages.
