4.3 Cost Proposal

4.2 Cost Proposal

By: Aaron Feng

The estimated construction cost for this project is €16,271.84 Euro, plus 10% variation. The overall total cost is €17,899.03 Euro. All the items are allocated into different categories. The main category includes: General tools &PPE, Safety Kit, Raw materials, Manufactured materials, specialist contractors and delivery charges. All the materials’ quantity are estimated based on the architecture design dimensions. And the unit price of each materials is referenced from local building material supplier website.

Some of the raw materials such as: clay, mud, sand, water and stone are marked green (appendix 2) in the cost analysis list which means they are assumed can be sourced naturally with no cost. However, actual site investigation is required to verify this assumption. Some of the manufactured materials and plants such as: mudbrick, bamboo door &fence and safety barrier and scaffolding are marked yellow (appendix 2) which means they are planned to be made on site. Mudbrick can be made with mud and mixture of clay, sand, and water. Raw Bamboo can be made into door and fence after boron treated. Safety barrier and scaffolding can be manually made of timber to prevent potential falling into the cisterns or falling from height. By making these materials and plants on-site can efficiently reduce the material cost.

The following assumptions are made for this cost analysis: - The international volunteers are financially self-supported or supported by the local government. - The labour force is sourced from local community with no cost. - Naturally, sourced materials listed in the cost analysis are sufficient and free to use. - Assume the tools and PPE listed are enough to use. - Assume no force majeure damage will be made to the project during the construction period which will incur extra cost. - All the specialist contractors are giving an estimate budget range based on the scope of the work, assume the actual price will not exceed 10% more than the estimate budget. - Assume the delivery charge will not exceed 10% more than the estimate budget.

A small budget is included in all categories of item, it is for the accessories that required at each stage of work. 10% variation is given to ensure the cost fits within the proposed budget.

The progress cost of the project will be claimed as following: - 40% at the beginning of the construction - 30% after the completion of the cisterns and toilet - Final 30% after the completion of the activity centre

As the project requires prepay for many materials and tools in order to start construction, therefore 40% of the overall budget is required at the beginning of the construction. A few specialist contractors are required during the construction of the main rooms, therefore 30% is required to ensure the progress of the construction. Final 30% will be used for the rest of the tasks. All the spending should be carefully record and feedback to the budget control department of this project to ensure the cost fits within the proposed budget.
