This project report focuses on the construction of a building using a sustainable modular theme. The introduction highlights the problems associated with on-site construction, such as waste generation and high costs, and emphasizes the benefits of modular construction, including speed, eco-friendliness, and cost-effectiveness. The report outlines the human, material, and financial resources required, along with a construction timeline. It explores techniques for cost planning and utilizes the critical path method (CPM) for project management. The project is divided into four phases: initiation, planning, execution, and closure. The conclusion emphasizes the benefits of modular construction in reducing waste, minimizing budgets, and achieving shorter build times. Recommendations are provided for future project improvements, including tracking, experienced team members, and proper management. The report is based on the provided assignment brief and includes references to support the analysis.
