Effects of inter-organizational conflicts on construction project added value in China

Purpose The purpose of this research is to investigate the effects of inter-organizational conflicts on the project added value in the Chinese construction industry, and also to examine the mediating effect of conflicts on project added value and the moderating effect of conflict management strategies. Design/methodology/approach A conceptual model was developed, and a structured questionnaire survey was conducted with 667 professionals. The structural equation modeling technique was used to analyze the data. Findings The results showed that task conflict, relationship conflict and process conflict were influenced by subject characteristics of project participants, bilateral relationship characteristics and project characteristics. Similarly, these three types of conflicts interact with each other. Meanwhile, these three types of conflicts influence the added value in construction projects, which are moderated by conflict management strategies. Under a collaborating strategy, task conflict and process conflict were positively associated with project added value, and relationship conflict was negatively associated with project added value. Under a competing strategy, task conflict, process conflict and relationship conflict were negatively associated with added value in construction projects. Therefore, the constructive and destructive effects of conflicts on project added value under different conflict management strategies are verified in Chinese construction projects. Research limitations/implications The variables may not be exhaustive for construction projects and most of them were applied in construction projects for the first time. As a result, their rationality and effectiveness could be further improved. The results implied that inter-organizational conflicts had a constructive effect on project added value and should attract broad attention for future research. Additionally, different driving factors had different influences on these conflicts, and even the driving factors can be divided into different dimensions. Practical implications This study provides a better understanding of the relationship between inter-organizational conflicts and added value in construction projects, and a reliable reference for the project manager to effectively deal with these conflicts. In addition, this research reveals the effects of conflicts on project added value and the path of conflicts transformation. This provides a useful reference for project managers to take advantage of the positive effect of task conflict and process conflict, and to avoid the negative effect of relationship conflict. Originality/value Very few studies attempted to examine the effects of inter-organizational conflicts on project added value in construction projects. Therefore, this research makes significant theoretical and practical contributions to the existing body of knowledge on the conflict management and project added value. This research provides an empirical evidence to support the viewpoint that different types of conflicts can be mutually transformed. Similarly, this study explains how conflicts present functional and dysfunctional effects in construction projects. Both of them are potential theoretical contributions to the existing body of knowledge.

Effects of contractual flexibility on conflict and project success in megaprojects

Purpose This study aims to investigate the influence of contractual flexibility on different types of conflict, determine if contractual flexibility is significantly correlated with project success between contracting parties, verify the mediating effect of project conflicts on the relationship between contractual flexibility and project success and examine the relationship between different types of conflicts and project success in megaprojects. Design/methodology/approach A theoretical model was developed and a structured questionnaire survey was conducted with 468 professionals. The structural equation modeling technique was used to analyze the data. Findings The results showed that both types of contractual flexibility – term and process flexibility – were correlated with and significantly positively affected project success, and term flexibility was found to have a greater influence. The introduction of project conflicts significantly weakened the relationship between contractual flexibility and project success, verifying the partial mediating effect of conflicts. All types of project conflicts play a destructive role in achieving project success; relationship conflict had the largest negative effect. Contractual flexibility affects two paths with respect to project success: the direct path (contractual flexibility → project success) and the indirect path (contractual flexibility → conflict → project success). The direct effect of contractual flexibility on project success is positive; the corresponding indirect effect is negative. The direct effect is greater than the corresponding indirect effect. Research limitations/implications Different types of conflicts may mutually transform to extent certain degree. However, this study did not address the potential influence of conflict transformation on project success. The results implied that more emphasis should be placed on contractual terms, particularly on developing flexible terms in the contractual document, when implementing megaprojects. Meanwhile, this study reveals the effects of conflicts on project success in megaprojects, which provides a useful reference for project stakeholders to avoid the negative effect of conflicts. Practical implications This study provides a better understanding of the relationship between contractual flexibility, types of conflicts in megaprojects and a reliable reference for the project manager to effectively deal with these related issues. This implies the contracting parties strengthen communication and cooperation to establish a trust mechanism, while reducing the negative influence of project conflicts and enhancing the positive effect of contractual flexibility. Originality/value Few studies have investigated the effects of contractual flexibility on conflict and project success in megaprojects; this study contributes significant theoretical and practical insights to contract management and conflict management and provides a reliable reference to achieve project success.

System Dynamics Model and Simulation of Employee Work-Family Conflict in the Construction Industry

The construction industry is a demanding work environment where employees’ work-family conflict is particularly prominent. This conflict has a significant impact on job and family satisfaction and performance of employees. In order to analyze the dynamic evolution of construction industry employee’s work-family conflict between work and family domains, this paper constructs a bi-directional dynamic model framework of work-family conflict by referring to the relevant literature. Consequently, a system dynamics model of employee’s work-family conflict in the construction industry is established, and a simulation is conducted. The simulation results indicate that construction industry employees experience work interference with family conflict (WIFC) levels which are significantly greater than the family interference with work conflict (FIWC) levels. This study also revealed that improving work flexibility and organizational support can have a positive impact on the satisfaction and performance of construction industry employees from a work and family perspective. Furthermore, improving family support can only significantly improve employee job satisfaction.

A bibliometric review of green building research 2000–2016

ABSTRACT This study presents a summary of green building research through a bibliometric approach. A total of 2980 articles published in 2000–2016 were reviewed and analyzed. The results indicated that green building research had been concentrated on the subject categories of engineering, environmental sciences & ecology, and construction & building technology, and the keywords ‘building envelope’ and ‘living wall’ obtained citation bursts in the recent years. Additionally, based on the cluster analysis and content analysis, the hot research topics were identified: green and cool roof, vertical greening systems, water efficiency, occupants’ comfort and satisfaction, financial benefits of green building, life cycle assessment and rating systems, green retrofit, green building project delivery, and information and communication technologies in green building. Knowledge gaps were detected in the areas of corporate social responsibility, the validation of real performance of green building, the ICT application in green building, as well as the safety and health risks in the construction process of green projects. Future research directions are recommended to fill these gaps and extend the body of green building research.

A Decision Model Assessing the Owner and Contractor’s Conflict Behaviors in Construction Projects

Considering the effects of the contractor’s conflict behaviors on the project benefit, a decision model between the owner and contractor’s conflict behaviors in construction projects was constructed using the principal-agent theory and game theory. The model was analyzed under nonconflicting and conflicting conditions, and a numerical simulation and example analysis were proposed to verify the constructed model’s conclusion. The results showed that the effort levels of the owner and contractor not only relate to benefit-sharing coefficient and effort outcome coefficient but also depend on the contractor’s ability of converting the conflict into benefit and the loss caused by conflict behaviors. A higher ability of converting conflicts into benefits and lower levels of the loss caused by conflict behaviors for the contractor lead to lower levels of the net benefit of the owner, conversely higher levels of the net benefit of the contractor. Balancing the contractor’s ability of converting conflicts into benefits and the loss caused by conflict behaviors lead to a more reasonable risk allocation between the owner and contractor, improving the effort level and net benefit. To add value to the construction project, the owner should establish an impartial and reasonable benefit-sharing mechanism, optimize the owner and contractor’s resource arrangement, maximize the positive effect of conflict on project benefits, and avoid the negative effect of conflict. Few studies to date have investigated the effects of conflict behaviors on project benefits in terms of modeling and simulation in construction projects. As such, this study bridges this gap and contributes significant theoretical and practical insights about managing conflict behaviors in an interorganizational context, thus enhancing performance in construction projects.
