Development of a Sustainable Digital Cost Estimation System for Large-Scale Construction Projects

Project Abstract

In recent years, the construction industry has experienced significant challenges related to cost overruns, inefficient resource allocation, and a pressing need for sustainable practices, particularly in large-scale projects that involve complex planning and execution processes. This research focuses on developing a comprehensive, sustainable digital cost estimation system designed to enhance accuracy, transparency, and environmental responsibility in large-scale construction project management. The study begins with a thorough review of existing cost estimation techniques, exploring traditional methods such as Detailed Quantity Surveying, as well as emerging digital tools including Building Information Modeling (BIM), artificial intelligence (AI), and machine learning algorithms. A critical analysis highlights the limitations of current approaches, such as manual data entry errors, lack of real-time updates, and insufficient integration of sustainability metrics. Building on this foundation, the research proposes a novel integrated platform that leverages advanced digital technologies to automate cost estimation processes while incorporating sustainability parameters, such as material lifecycle impacts, energy efficiency, and waste reduction strategies. The system design is guided by principles of user-friendliness, scalability, and adaptability across various project scales and types. To ensure the sustainability aspect, the system incorporates eco-friendly material databases, environmental impact assessment tools, and lifecycle costing modules that promote green construction practices. Methodologically, the project employs a mixed-methods approach, blending qualitative interviews with industry stakeholders—including quantity surveyors, project managers, and environmental consultants—with quantitative data analysis derived from case studies of large-scale projects. Prototype development follows an iterative process involving stages of requirements gathering, system architecture design, algorithms development, and usability testing. The system's effectiveness is evaluated through multiple case studies, benchmarked against traditional estimation methods to assess improvements in accuracy, speed, and sustainability metrics. The findings demonstrate that the digital system significantly reduces estimation errors, improves project planning efficiency, and promotes sustainable resource utilization, ultimately leading to cost savings and environmental benefits. The research also identifies challenges such as data integration complexities, user adoption barriers, and the need for standardized digital protocols, which inform recommendations for future enhancements. Furthermore, the project underscores the importance of integrating sustainability into the core of project planning and emphasizes the role of digital transformation in achieving sustainable development goals within the construction industry. Overall, this study contributes a practical and innovative tool that aligns financial, environmental, and operational objectives, paving the way for more sustainable and efficient large-scale construction project management.

Project Overview

What This Project Is About

This project focuses on creating a digital system to estimate the costs of large construction projects. It aims to develop a tool that can quickly and accurately predict how much a building or infrastructure will cost. The system will use digital technology to improve how costs are calculated, making the process faster and more reliable. The project combines knowledge of construction, finance, and computer technology to build a tool that helps engineers, project managers, and clients plan projects better.

The Problem It Addresses

Currently, cost estimation in large construction projects often relies on manual methods that can be slow and prone to errors. Many existing systems are not sustainable or adaptable to new technologies, which can lead to inaccurate budgets and delays. This project addresses the need for a modern, digital approach that can provide accurate cost estimates efficiently. Improving this process helps save money, reduce waste, and support better decision-making in construction projects.
