How to make an estimate of expenses
Choose the appropriate model cost estimate plan for your case. Find in reliable sources information about existing regulations and quotations for the required work and materials.
Rewrite the quantity and quality of the work that will need to be done and the costs for them. In order to take into account all the necessary moments, it will be necessary to delve into the subtleties of the process, to become, to some extent, a narrow specialist.
Count the required amount of materials, multiply by the corresponding prices. Do not forget to add the number of hours worked for the work at the appropriate rates. The amount that you got is direct production costs.
Once again carefully study the list of materials, the prices for them, check the correctness of their arithmetic calculations. Then again check the standards, which are stipulated for the performance of certain works and the corresponding rates.
Do not be afraid to put a few extra hours in the estimate, haste at this stage can cost you dearly when it comes to the fact that you bought few materials, the work is forced simple, and the workers have an hourly payment.
Think carefully about what unforeseen circumstances can hamper construction, can they be prevented? It makes sense to allocate a certain amount for this in advance and keep it as an untouchable stock.
Include in the estimate all the additional costs that you can recall. If the employees work for you officially, IT costs and payment of taxes are also included in the estimate. Garbage removal, transportation costs, too, please specify. As a rule, overhead increases the initial cost of construction by at least 15%.
