Construction estimates are drawn up in stages for specific types of costs and works. In this case, the calculations are of a general nature with the calculation of the total cost of the project. While not absolute, the estimate during the construction process can be refined and detailed.
Instructions
Step 1
Before making estimates in construction, determine the regulatory framework on the basis of which the estimate will be carried out. These can be both state standards and individual ones. For the correct preparation of the estimate, it is required to find out for which region it will be carried out. This concerns the difference in costs due to the peculiarities of the climate, geographic location. It is necessary to determine the coefficients used in the estimate to fill in the uniform rates of the local estimate calculation.
Step 2
At the pre-design stage, it is necessary to calculate the preliminary cost of construction. When drawing up such an estimate, due to the absence of a project, extremely enlarged indicators are used, such as, for example, hectares, cubic and square meters. It is also possible to use indicators of similar objects.
Step 3
At the design stage, the estimate, having an enlarged view, requires more accurate calculations. Based on the design drawings, it is necessary to develop a consolidated estimate of the entire construction. And to draw up a full estimate, it is required to draw up local and object calculations for certain types of costs. The estimate also needs to include exploration and design costs. Calculations are carried out separately by type of work, while they are grouped by structural elements of the object. In case of clarification of the nature and methods of work, the estimated cost must be adjusted.
Step 4
Overhead costs are a separate section in the estimate. Labor remuneration is calculated in the local estimate for each contractor separately. In addition to the main cost items, others can be calculated. This can be commissioning, maintenance of operating personnel and more. It is necessary to develop and draw up estimates in construction on the basis of the current state, industry, territorial regulations.
