Assessing Cost Management Practices in Green Construction Projects: A Case Study of EcoBuild Ltd.

Thesis Abstract

The increasing emphasis on sustainable development has positioned green construction as a pivotal component of modern architectural and engineering practices, yet effective cost management remains a critical challenge impeding its widespread adoption. This study investigates the prevailing cost management practices within green construction projects, focusing on EcoBuild Ltd., a leading contractor specializing in environmentally sustainable building initiatives. The primary aim is to evaluate the adequacy, efficiency, and effectiveness of current cost control measures and identify factors influencing their performance to provide strategic insights for improving financial outcomes in green construction. The specific objectives include (1) assessing contemporary cost management practices employed by EcoBuild Ltd.; (2) examining the impact of green construction-specific cost factors on project budgeting; (3) identifying challenges faced in implementing cost control measures within sustainable projects; and (4) proposing frameworks for enhancing cost management efficiency aligned with green building standards. The research adopts a mixed-methods design, integrating quantitative data from surveys and project performance records with qualitative insights from semi-structured interviews. The population comprises project managers, cost engineers, and financial controllers within EcoBuild Ltd., with a purposive sample of 50 professionals selected through stratified sampling to ensure representation across diverse project types and stages. Quantitative data on project costs, variance analyses, and management practices are gathered through structured questionnaires and reviewed project documentation, while qualitative insights are obtained via thematic interviews. To ensure validity and reliability, the survey instrument is pre-tested with a pilot sample of 10 professionals, with Cronbach’s alpha exceeding 0.8, indicating high internal consistency. Data analysis involves descriptive statistics to profile current practices, multiple regression analysis to examine predictors of cost performance, and thematic analysis for interview transcripts to explore contextual challenges and perceptions. The findings are expected to reveal that while EcoBuild Ltd. adopts comprehensive green-specific cost management practices, inconsistencies and resource constraints hinder optimal cost control. Particular green construction cost drivers—such as sustainable material premiums, lifecycle cost considerations, and regulatory compliance expenses—are anticipated to significantly influence project budgets, often leading to cost overruns if not adequately managed. Challenges include limited expertise in green-specific cost assessment, resistance to cost control measures, and insufficient integration of sustainability standards into existing cost frameworks. Regression analysis is projected to demonstrate that proactive risk management and detailed cost forecasting significantly improve project cost performance. The thematic analysis is expected to uncover organizational and industry-wide barriers, providing nuanced understanding of real-world complexities faced by practitioners. This study contributes to the existing body of knowledge by filling gaps concerning the integration of green building principles with traditional cost management frameworks. It offers a conceptual model delineating the relationship between green-specific cost drivers, management practices, and project performance, extending current theories such as the Agency Theory and the Resource-Based View to the context of sustainable construction. The insights generated will assist construction firms, policymakers, and industry stakeholders in designing targeted interventions and developing tailored cost management strategies for green projects, ultimately promoting more sustainable and financially viable construction practices. The study concludes that enhancing professional capacity, adopting integrated project delivery models, and institutionalizing green cost management standards are essential for improving financial efficiencies in green construction. Recommendations include implementing specialized training programs, developing green-specific cost estimation guidelines, and fostering collaborative decision-making platforms. Future research is suggested to explore the applicability of these frameworks across different geographic contexts and project scales, to establish generalizable best practices for sustainable construction cost management.
