Development of a Digital Cost Estimation Model for Sustainable Building Projects

Project Abstract

The rapid advancement of digital technologies has transformed the construction industry, offering new opportunities for enhancing efficiency, accuracy, and sustainability in project management and delivery. This research aims to develop a comprehensive digital cost estimation model tailored specifically for sustainable building projects, addressing the unique complexities and demands associated with environmentally conscious construction. The study begins by examining existing traditional cost estimation techniques, identifying their limitations in integrating sustainability metrics and adapting to dynamic project variables. Subsequently, it explores various digital tools, software, and methodologies such as Building Information Modeling (BIM), Artificial Intelligence (AI), and data analytics, assessing their capabilities in improving cost accuracy and decision-making processes in sustainable construction. A hybrid framework is proposed, combining these advanced digital approaches to establish an intelligent, real-time cost estimation model capable of incorporating sustainability factors such as energy efficiency, material lifecycle costs, and carbon footprint considerations. The research methodology involves a mixed-method approach, employing empirical data collection from case studies of recent sustainable building projects, expert interviews, and surveys with industry professionals to validate the model's effectiveness. Additionally, the development phase encompasses algorithm design, prototype creation, and iterative testing to refine the model's predictive accuracy and user interface. The results demonstrate that the digital model significantly enhances the precision of cost predictions, reduces estimation errors, and facilitates better planning and resource allocation, ultimately contributing to cost savings and improved project sustainability. Sensitivity analysis highlights the model's robustness across different project types, scales, and geographical locations, confirming its adaptability and utility in diverse contexts. Furthermore, the integration of sustainability metrics into the estimation process provides a more holistic view of project costs, enabling stakeholders to make informed decisions that align with environmental objectives without compromising financial viability. The research also evaluates potential implementation challenges, including technological adoption barriers, data security, and required workforce training, offering strategic recommendations for successful deployment. This innovative model sets a foundation for future research in digitalization within the construction industry, emphasizing the critical role of technology in fostering sustainable development. The findings contribute valuable insights to quantity surveying professionals, project managers, and policymakers aiming to enhance project efficiency, sustainability, and competitiveness. Overall, this study provides a practical and scalable solution that bridges the gap between traditional cost estimation practices and the evolving digital landscape, paving the way for more resilient and environmentally responsible construction practices worldwide. The proposed model not only optimizes project costs but also promotes sustainable development principles, aligning economic feasibility with ecological stewardship.

Project Overview

What This Project Is About

---

This project focuses on creating a computer-based tool that helps estimate the costs involved in building environmentally friendly, or sustainable, buildings. It aims to develop a system that can quickly and accurately calculate how much a sustainable building project might cost. The goal is to make it easier for builders, architects, and project managers to plan and budget for green building projects using digital technology.

The Problem It Addresses

---

Currently, estimating costs for sustainable building projects can be complicated and time-consuming because of the many new materials and methods involved. Many existing estimation methods are manual and may not reflect the latest sustainable building practices. This creates challenges in planning and can lead to either underestimated costs or budget overruns, which can delay or increase the price of eco-friendly projects. The project aims to fill this gap by providing a modern, efficient way to estimate costs for green construction efforts.
