Calculation of prices for design documentation (DD) is based on the “Reference book of basic prices for development of design documentation for customized equipment” issued in 1998 by GP “TsENTRINVESTproekt” by the Ministry of Land Policy and Construction of Russia and CJSC “PromtransNIIproekt”, and enacted as agreed with the Committee of the RF for machine building on 14.10.96 No. 8/3-4-271.

This reference book is recommended for determination of basic prices for subsequent forming of contract prices for development of design documentation for customized equipment (DDCE).

Which expenses are included in the price?

Prices include expenses on the following:

• design supervision;

• compliance assessment of text document;

• compliance assessment of drawing;

• process inspection;

• comparison of copy with original.

Prices do not include:

• expenses on business trips;
• research and development works;
• participation in testing, correction of DDCE for prototype samples.
• Classification of works according to complexity and novelty.
• Products or projects for which design documentation development is necessary are divided into 6 complexity groups and 5 novelty groups.

Complexity is determined according to one of the following features:

Характеристика групп сложности

• Functional description of the product. This feature can be used to classify development of DDCE on the whole;
• Quantity of drawing sizes. This feature can be used to classify development of general arrangement drawings, lines, dimensional and mounting drawings, as well as part drawing;
• Quantity of parts included in an assembly drawing. This feature is used to classify an assembly drawing;
• Quantity of diagram elements. This feature is used to classify electric, hydraulic, pneumatic and kinetic diagrams.

Novelty is determined according to one of the following features:

• Functional description of the product. This feature can be used to classify development of DDCE for a product on the whole;
• Quantity of indicators of product technical level and quality (in compliance with GOST 2.116-84), which are specified in the technical assignment (TA) for DDCE development.

Characteristic of novelty groups

Determination of basic price for design documentation development.

A basic price of design documentation development is determined separately for each type of DDCE of the corresponding development stage using the formula:

P_b = P × K_l × K_s × K_c × K_st × K_sh, where

P_b – basic price of development of the corresponding DDCE type;

P – price of DDCE development (Table 1);

K_l – coefficient of product labour intensity (Tables 2-8);

K_s – coefficient for drawing size (Table 9);

K_c – coefficient for specific conditions of DDCE execution (Table 10);

K_st – coefficient of DDCE development stadiality (Table 11);

K_sh – coefficient of drawings (sheets), lines of text of the corresponding DDCE type.

Prices for design documentation development

Note: prices are established as of 01.01.95 in the price scale adopted from 01.10.2020.

Coefficient of equipment labour intensity (K_l) is determined as per Tables 2-8:

Table 2 – Determination of K_l for assembly drawing (to item 1 of Table 1)

Table 3 – Determination of Kl for a general arrangement drawing and part drawing (to items 2, 6 of Table 1)

Table 4 – Determination of Kl for lines, dimensional and mounting drawings (to items 3, 4, 5 of Table 1)

Table 5 – Determination of K_l for electric diagrams (to items 7-9 of Table 1)

Table 6 – Determination of K_l for hydraulic, pneumatic and kinematic diagrams (to items 10, 11 of Table 1)

Table 7 – Determination of K_l for preparation, fulfillment and drawing-up of technical, technical/economic and estimate calculations (to item 13 of Table 1)

Table 8 – Determination of K_l for development of an explanatory note at all stages of development of DDCE and other text documents

If a drawing or other design documentation is prepared on a sheet the size of which differs from the size given in Table 1 (items 1-11), correction coefficient (Ks) is applied to the price depending on actual sheet size (Table 9).

Table 9

If there are specific conditions of DDCE development (Table 10), correction coefficient (Kc) is applied to prices (P):

Table 10

In compliance with GOST 2.103-2013, DDCE development prices are given in the following stages:

• technical proposal;

• initial design

• technical design;

• working documentation.

If the technical assignment provides for stadiality which differs from the aforesaid one, correction coefficient (Kst) is applied to prices in compliance with Table 11.
