The Role of Quantity Surveyors in Sustainable Construction Practices

CHAPTER ONE

1.1 Background of the Study

Sustainability has become a key focus in the global construction industry. As the sector continues to expand, its environmental, social, and economic impacts have raised major concerns. Construction activities contribute significantly to energy consumption, waste generation, and carbon emissions (World Green Building Council, 2020). To address these issues, professionals are adopting sustainable construction practices that emphasize resource efficiency, environmental protection, and long-term economic value.

Quantity surveyors play an essential role in achieving sustainable construction goals. Traditionally, their duties focused on cost estimation, tendering, and contract administration. However, their role has evolved to include advising on sustainable materials, life cycle costing, waste reduction, and energy-efficient design (Ashworth & Perera, 2018). By integrating sustainability into cost management, quantity surveyors help clients make informed decisions that balance financial feasibility with environmental responsibility.

According to Ofori (2019), sustainable construction is not only about environmental performance but also about achieving social and economic benefits. Quantity surveyors contribute to this by promoting value engineering, cost-effective green technologies, and efficient resource allocation. Despite their importance, many quantity surveyors still face challenges in applying sustainable principles due to inadequate training, lack of awareness, and limited access to sustainability data.

This study examines the role of quantity surveyors in promoting sustainable construction practices. It explores their responsibilities, challenges, and the impact of sustainability on cost management and project delivery.

1.2 Statement of the Problem

The construction industry continues to face sustainability challenges such as resource depletion, high energy use, and waste generation. While quantity surveyors have the potential to influence sustainable decisions, their involvement is often limited. Many professionals focus primarily on cost minimization rather than long-term value optimization (Ameh & Osegbo, 2011).

Inadequate knowledge of green building standards, lack of client support, and insufficient institutional frameworks further limit the contribution of quantity surveyors to sustainability. As a result, the integration of sustainable practices into construction cost management remains weak. This study seeks to investigate how quantity surveyors can strengthen their role in achieving sustainable construction outcomes.

1.3 Aim and Objectives of the Study

The main aim of this study is to examine the role of quantity surveyors in promoting sustainable construction practices.

The specific objectives are to:

1. Identify the responsibilities of quantity surveyors in sustainable construction.

2. Examine the level of awareness and implementation of sustainability principles among quantity surveyors.

3. Assess the challenges faced by quantity surveyors in promoting sustainable construction.

4. Recommend strategies to enhance the involvement of quantity surveyors in sustainable development.

1.4 Research Questions

1. What are the key roles of quantity surveyors in sustainable construction projects?

2. What is the level of awareness of sustainability principles among quantity surveyors?

3. What challenges limit their participation in sustainable construction practices?

4. What strategies can strengthen their contribution to sustainability in the construction industry?

1.5 Significance of the Study

This study is significant because it highlights the evolving role of quantity surveyors in achieving sustainable construction. It provides useful insights into how cost management professionals can integrate environmental and economic goals in their work. According to Ashworth and Perera (2018), quantity surveyors are in a strategic position to influence sustainable decisions during the planning and execution stages of a project.

The findings will benefit clients, contractors, policymakers, and professional institutions by promoting policies that encourage sustainable construction. It also contributes to the growing body of knowledge on green cost management and environmental responsibility in the construction sector.

1.6 Scope of the Study

The study focuses on the involvement of quantity surveyors in sustainable construction practices, particularly in building projects. It examines their roles, challenges, and contributions at different project stages, including design, procurement, and post-construction. The research targets practicing quantity surveyors, consultants, and project managers familiar with sustainable development.

1.7 Limitations of the Study

This research may be limited by inadequate access to sustainability data and the unwillingness of professionals to share detailed project information. Time constraints may also restrict the number of participants. Despite these challenges, reliable and relevant data will be collected to ensure accuracy and credibility of findings.

1.8 Definition of Terms

• Sustainable Construction: The practice of creating buildings that minimize environmental impact, optimize resource use, and support economic and social well-being (World Green Building Council, 2020).

• Quantity Surveyor: A professional responsible for managing construction costs, contracts, and value for money throughout the project lifecycle.

• Life Cycle Costing: A method used to evaluate the total cost of ownership of a building over its life span, including construction, operation, and maintenance costs.

• Green Building: A building designed and constructed to reduce negative environmental impacts and improve occupant well-being.
