Estimates for design work are very important in construction. They are usually compiled for any types of costs and works in stages. They are often of a general nature, including calculations of the total cost of the project. So, how to make an estimate for design work?
Instructions
Step 1
Before proceeding with the calculation of estimates for design work, it is necessary to determine the regulatory framework. It is from this base that the estimate will be carried out. As such a base can serve as standards established by the state, and individual. For the most accurate budgeting, it will be necessary to establish which area the project is designed for. It is very important. After all, the differences in costs in different climatic zones, geographical areas are quite significant. Therefore, it is simply necessary, first of all, to determine the coefficients used in a particular estimate in order to fill in the local estimate calculation with uniform prices.
Step 2
The preliminary cost of construction must be calculated at the pre-design stage. When drawing up a preliminary estimate, the maximum aggregated indicators should be used. These include, for example, hectares, square meters and cubic meters. In addition, the use of indicators of similar construction projects is permissible.
Step 3
More accurate calculations are needed at the design stage. After all, there are already design drawings. On their basis, you need to carry out a full estimate of the entire construction. For such an estimate, it is necessary to draw up object and local calculations for each separate type of cost. All design and survey costs must be included in the total estimate in advance. Calculations should be carried out for all types of work separately. In addition, they must be grouped according to the structural elements of the object. The estimated cost during the development of the project can be repeatedly adjusted, in case of clarification of the methods and nature of the work.
Step 4
Overhead costs in the estimate should be a separate section. Separately for each contractor, wages must be calculated in the local estimate. In addition to the most basic cost items, others can be calculated in the estimate.
