Development of a Sustainable Cost Estimation Model for Affordable Housing Projects

Project Abstract

The escalating costs associated with affordable housing development pose significant challenges to stakeholders aiming to deliver quality yet cost-effective solutions within limited budgets. This research aims to develop a robust, sustainable cost estimation model that enhances accuracy and reliability in forecasting the total expenditure of affordable housing projects, thereby facilitating better financial planning, resource allocation, and decision-making processes. The study begins with a comprehensive review of existing cost estimation methods, identifying their strengths, limitations, and applicability in the context of affordable housing. It investigates various factors influencing project costs, including material prices, labor costs, project duration, design complexities, and socio-economic variables, emphasizing sustainability considerations such as environmental impacts and resource efficiency. Using a mixed-methods approach, the research combines qualitative analyses—through interviews and expert consultations with architects, quantity surveyors, and construction managers—with quantitative data collection from recent affordable housing projects across different regions. The data collected is analyzed using statistical tools and machine learning algorithms to identify patterns and establish predictive relationships between project variables and total costs. The core contribution involves developing a dynamic, adaptable cost estimation model powered by algorithms capable of integrating real-time data and contextual variables to improve accuracy over traditional static models. The model is validated through case studies, comparing its predictions against actual project costs and existing estimation methods to assess its performance, robustness, and capacity to incorporate sustainability metrics. A key feature of the developed model is its ability to account for unforeseen fluctuations in economic factors such as inflation, material shortages, and policy changes, ensuring its applicability in volatile market conditions. The research also explores how integrating sustainability indices into cost estimation can promote environmentally responsible building practices without substantially increasing project budgets. Findings reveal that the proposed model outperforms conventional methods in predictive precision, flexibility, and sustainability integration, offering stakeholders a comprehensive tool for planning and managing affordable housing projects more effectively. This development has the potential to contribute significantly to policy formulation, project management, and technical practices within the construction industry, encouraging sustainable development and cost efficiency. The study concludes with recommendations for implementing the model in various contexts, highlighting necessary adjustments and future research directions to refine its capabilities further. Overall, this research advances the field of quantity surveying by providing an innovative solution to the persistent challenges of cost overrun and sustainability in affordable housing development, ultimately supporting the goal of delivering resilient, economically feasible, and environmentally sustainable housing solutions.

Project Overview

What This Project Is About

---

This project is about creating a simple and reliable way to estimate how much it costs to build affordable housing. It aims to develop a model that predicts costs based on different factors like size, location, materials, and design. The goal is to help builders, developers, and planners understand expenses better so they can plan affordable housing projects more efficiently and sustainably.

The Problem It Addresses

---

Many affordable housing projects experience budget overruns because cost estimates are often inaccurate or incomplete. This can lead to delays, increased costs, or even project failures. Existing models may not consider all the important factors or be adaptable to different situations. Addressing this gap will help make better financial planning possible, ensuring more affordable homes are built for those in need. It also supports sustainable development by reducing waste and unnecessary expenses.
