Drawing up a bill of quantities.
After specifying the requirements for the completeness of the previous or preparatory processes and descriptions technological sequence performing operations should determine the scope of work.
When developing a technological map for the device of structures made of monolithic or prefabricated reinforced concrete, before drawing up a bill of quantities, it is necessary to draw up a specification of monolithic reinforced concrete structures (Table 2.1) or a specification of mounting elements (Table 2.2), respectively.
Filling in the Specification of monolithic reinforced concrete structures should begin with the definition of all elements and structures, which are related to the developed technological plan, according to the working drawings. Their list is entered in column 2. Columns 3, 4, 5, 6 and 8 are filled in on the basis of working drawings. The results of the product of columns 4, 5, 6 are entered in column 7. The total volume of concrete for all elements (column 9) is determined by the product of the values in column 7 by the values in column 8.
Table 2.1
Specification of monolithic reinforced concrete structures
Filling in the specification of mounting elements is also carried out on the basis of the adopted architectural and planning and constructive solutions... Columns 2-8, 10 are filled in in accordance with the working drawings. Column 9 is filled in only for lamellar elements (walls, floor slabs, etc.) by multiplying the values of column 4 by column 5. Columns 11 and 12 contain the results of the product of the values of column 7 by 10 and columns 8 by 10, respectively.

The bill of quantities (Table 2.3) includes all the main and auxiliary processes that are carried out in the projected complex construction process. Determination of the scope of work is carried out using the specification of elements, as well as working drawings. Column 2 sequentially records all the processes carried out in the production of the type of work for which the technological map is being developed. Units of measurement in column 3 must correspond to those given in the ENiR on this process enlarged meters. Next, column 5 is filled out with the calculation formulas, or, if the calculation was made earlier, with an indication of the place in the calculation and explanatory note. The calculation results are entered in column 4, taking into account the units of measurement given in column 3.

There are "alternative estimate documents" order at will. Sample forms of documents are mainly used for internal use in order to view in detail and calculate the costs included in the estimate documentation. They eliminate the need to use a calculator and have any deep knowledge of the estimate business.
Examples of estimates and calculations for construction, repair and installation:
Examples, sample documents are presented tentatively, therefore, they are a guideline for understanding the work performed. All requirements for estimate documentation and acts are indicated in the letter and then agreed with us.
