The Role of Supervising Consultants in Enhancing Communication Effectiveness in Construction Projects: Evidence from Aceh Province, Indonesia

Abstract

Construction projects involve complex, multi-stakeholder interactions in which ineffective communication often leads to delays, cost overruns, and reduced project quality, particularly in developing regions such as Aceh, Indonesia. This study examines the role of supervising consultants in enhancing communication effectiveness by identifying key determinants that influence communication outcomes in construction projects. A quantitative research design was employed using a structured questionnaire distributed to 33 Small (K) and Medium (M) grade construction supervision consultancy firms. Data were analyzed using descriptive statistics, Pearson’s correlation, and multiple linear regression. The results indicate that all examined factors are perceived as highly important, with supervising consultant competence ranked highest. However, regression analysis reveals that only communication management has a statistically significant positive effect on communication effectiveness (β = 0.465, p < 0.05). Correlation analysis further shows that communication management, communication methods, and information flow are significantly associated with communication effectiveness, while consultant competence, supervision effectiveness, and project coordination are not statistically significant. These findings demonstrate that managerial and relational factors, including teamwork, openness, and shared understanding, are more influential than technical or structural factors. The study concludes that communication effectiveness in construction projects is primarily driven by how communication processes are managed rather than by individual competence or coordination alone. Strengthening communication management practices is therefore essential to improve coordination, minimize misunderstandings, and enhance project performance.
