An estimate is a document that takes into account the materials necessary for the production of work, their quantity and cost. The cost estimate may also include the cost of working with these materials, if you order their execution by a third-party organization. The estimate can be drawn up as a standard package of documents for each type of material and work with it, or it can be made in the form of costing and resources per unit of material. The estimate is the basis for determining costs and capital investments.
Instructions
Step 1
Start the budgeting of the object with the preparation of local estimates for certain types of work. Local estimates are based on approved or negotiated prices. The local estimate indicates the materials necessary for each type of work, the cost of a unit of material and the estimated need for them. In the final estimate for the object, all local estimates are taken into account, the calculation of the cost of the entire object is given.
Step 2
In the consolidated estimate calculation, give the enlarged and generalized indicators, take into account in it certain types of costs - for the purchase of construction equipment, finishing work, the cost of paints and varnishes, the preparation of a package of documents for a land plot, reimbursement of expenses for clearing the site and demolishing buildings and structures.
Step 3
To draw up an estimate, in addition to special construction education, necessary to correctly assess the composition and scope of work, the number and range of building materials, you will need Excel spreadsheets or special programs for making estimates. They can be found on the Internet, many of them are free. The databases that are built into this special software already contain the main types of work, their cost, construction materials and their consumption rates, etc. It is possible to correct data, enter new information.
Step 4
In the event that the building object is large, it is better to divide the estimate into stages, which will be paid separately, as it is completed. Provide in the estimate overhead costs, which include the maintenance of the administrative level of the contractor's company and the cost of transporting construction materials. Consider the percentage of additional costs that are difficult to foresee right away.
Step 5
Take into account in the estimate all the costs for the implementation of this project, make a calculation of the necessary funds, determine the cost of wages, calculate the cost of building materials.
