 Z_{j}: general constructional cost corresponding to the group or type of j^{th} constructional activity, structural unit or works part of works or works items. The general constructional cost can be the incomplete or complete general constructional cost as guided in Appendix 03 of this Circular.
 T: tax rate of value added tax under the current regulations
1.3. Determining the cost of equipment
Based on the specific conditions, information source and data of project, the cost of equipment of project is determined as follows:
1.3.1. Where the project has detailed information sources and data of works equipment and technological equipment, amount, type, value of each equipment or value of the entire technological line and the price of one ton, unit or the respective entire equipment line, the cost of project equipment (G_{TB}) is equal to the total costs of equipment of works under the project.
The project has information on the synchronous offer price for works equipment or technological equipment of the manufacturer or the equipment provider, the cost of equipment (G_{TB}) of the project can be referred directly from the quotations or the offer price of synchronous equipment on the basis of selecting the lowest price between the manufacturer or equipment provider’s quotations (except for the equipment introduced for the first time and being unique on the market) to ensure the satisfaction of requirements for supply of equipment to the works or the price of equipment with similar capacity, technology and origin on the market at the time of calculation or of the works having similar equipment which was or is being implemented.

In case of estimation, the total of such costs (excluding the loan interest during the time of project implementation and initial working capital) shall not exceed 15% of total constructional costs and cost of project equipment.
The initial working capital (V_{Lđ}) (for the business and production projects) and loan interest during the time of project implementation (L_{Vay}) (for project using the loan interest), depending on the specific condition, progress and capital allocation plan of each project for determination.
1.5. Determining the contingency cost
The contingency cost (G_{DP}) is determined by the total contingency cost for the factors of generated work volume (G_{DP1}) and the contingency cost due to the price slippage factors (G_{DP2}) by the following formula:
G_{DP} = G_{DP}_{1} + G_{DP2}_{ }(1.4)
The contingency cost for the factors of generated work volume (G_{DP1}) is determined by the following formula:
G_{DP}_{1} = (G_{BT, TĐC} + G_{XD} + G_{TB} + G_{QLD}_{A} + G_{TV} + G_{K}) x k_{ps} (1.5)
In which:
 k_{p}_{s}: contingency percentage for volume of work generated, this percentage depends on complexity of works under the project and geological condition of works where the works is built and the percentage is k_{ps} ≤ 10%.
For the construction investment project, only making the report on economical  technical construction investment, k_{ps} ≤ 5%.
The contingency cost due to price slippage factors (G_{DP2}) is determined on the basis of length of time of works construction of the project, capital allocation progress by year, average yearly fluctuation of price of works construction of the last 03 years in line with type of works, by construction area taking into account the fluctuation trend of factors of cost and price in the region and in the world. The contingency cost due to the price slippage factors (G_{DP2}) is determined by the following formula:
(1.6)
In which:
 T: length of time of implementation of construction investment project, T>1 (year);
 t: ordinal number of capital allocation year under the project implementation plan, t = 1÷T;
 V_{t}: investment capital before contingency under the plan carried out in t^{th} year;
 L_{V}_{ayt}: cost of loan interest of investment capital carried out as planned in t^{th} year;
 I_{XDCT}_{bq}: Construction price index used to calculate the contingency for the price slippage factors is determined by calculating the average of uninterrupted construction price index by the type of works of at least the last 03 years compared with the time of comparison (not taking into account the times of unusual fluctuation of price of material, fuel and constructional materials) by the following formula:
(1.7)
In which:
T: number of years (nearest year compared with the time of calculation and use to determine I_{XDCTbq}; T≥3;
I_{n}: construction price index of year n^{th} selected;
I_{n+1}: construction price index of year n+1;
± ∆I_{XDCT}: the average fluctuation of construction price index by year of works construction compared with the average price slippage of the year which is calculated and is determined on the basis of forecasting of fluctuation trend of factors of costs and price in the region and in the world by the experience of expert.
2. Method of determination by works construction investment capital
Where the total construction investment is determined by scale, power or service capacity based on the basic design, the norm of constructional cost rate (S_{XD}) and equipment cost rate (S_{TB}) or the overall construction price can be used to calculate the construction investment cost for each works under the project and the total construction investment is determined by the formula 1.1 of this Appendix.
2.1. Determining the constructional cost
The constructional cost of project (G_{XD}) is equal to the total constructional costs of works, works items or group of constructional activities, structural unit or works part of project determined by the formula (1.2) in Section 1.2, part I of this Appendix. The cost of construction of works, works items or group of constructional activities, structural unit or works part (G_{XDCT}) is determined by the formula
G_{XDCT} = S_{XD} x P + C_{CTSXD} (1.8)
In which:
 S_{XD}: constructional cost rate calculated for one power unit or service capacity announced by the Ministry of Construction or agreed upon for announcement or referred from the data of constructional cost rate of similar projects on type, scale and features of project.
 P: production capacity or service capacity of works, works items or group of constructional activities, structural unit or works part of project.
 C_{CTSXD}: cost items not yet calculated in the constructional cost rate or in the overall construction unit price calculated for 01 power unit, service capacity of works, works items of the project;
2.2. Determining the cost of equipment
The cost of works equipment and technological equipment of the project (G_{TB}) is equal to the total costs of works equipment and technological equipment of the works under the project. The cost of equipment of works (G_{TBCT}) is determined by the following formula:

In which:
 S_{TB}: cost rate of works equipment and technological equipment calculated for one power unit and service capacity of works is announced by the Ministry of Construction or agreed upon for announcement or referred from the data of constructional cost rate of similar projects on type, scale and features of project.
 P: production power or service capacity of works, works items or group of constructional activities, structural unit or works part of project.
 C_{CTSTB}: cost items not yet calculated in the cost rate of works equipment under the project.
2.3. Determining other costs
The cost of compensation, assistance and relocation; cost of project management, construction investment consultation, other costs and contingency cost are determined in accordance with the instructions in Section 1.1, 1.4, Section 1.5, Part I of this Appendix.
3. Method of determination from data of cost of similar works which were or are being implemented
The similar projects are the projects having similar construction works of the same type, works level, scale, nature of project and power of technological line (for works of production).
Depending on the nature and particularity of similar projects which have been implemented and the information and data of project, it is likely to use one of the following methods to determine the total investment:
3.1. Where there are sufficient information and data on the cost of construction investment of similar works and work items which were or are being implemented, the total investment is determined by the following formula:
V= (1.10)
In which:
 n: a number of similar works which were or are being implemented;
 i: ordinal number of similar works which were or are being implemented;
 G_{T}_{ti}: cost of construction investment of similar works which were implemented i^{th} of investment project (i = 1÷n);
 H_{t}: coefficient converting the cost to the time of making the construction investment project. The coefficient H_{t} is determined by the construction price index. The original year of price index must be consistent to use this coefficient.
 H_{kv}: coefficient converting the cost of construction area. The coefficient H_{kv} is determined by the expert method based on the comparison of the price level of area where the project investment is being implemented and the price level of area of similar project used for calculation;
 C_{Tt}_{i}: Costs which have not yet been calculated or have been calculated in the cost of similar works construction or i^{th} works items which were implemented.
In case of adding the necessary costs of the project under calculation but not included in the cost of construction investment or works or works items of similar project, then C_{T}_{ti} >0. Where the costs included in the cost of construction investment of works or works item of the similar project but not consistent or unnecessary for the project under calculation, then C_{T}_{ti} <>. In case of deduction, C_{T}_{ti}_{ }is multiplied by the coefficients H_{t} and H_{kv}.
3.2. If with the data source of cost of construction investment of similar works or works items which were or are being implemented, only the cost of construction and the cost of equipment of works can be determined, it is necessary to convert these costs to the time of project preparation, location of project construction simultaneously add other necessary costs (if any). On the basis of costs of construction, technological equipment and the equipment of works converted, costs of compensation, assistance and relocation, project management, construction investment consultation, other costs and contingency cost are determined similarly in the instructions in Section 1.1, 1.4, Section 1.5, Part I of this Appendix.
4. Method of combination to determine the total construction investment
For the projects having many works, depending on the specific conditions and requirements of the project and source of data, it is likely to apply the combination of above methods to determine the total investment of the works construction investment project.

METHOD OF DETERMINATION OF CONSTRUCTION ESTIMATE
(Issued with Circular No. 06/2016/TTBXD dated 10/3/2016 of the Ministry of Construction)
I. WORKS CONSTRUCTION ESTIMATE
The works construction estimate is determined by the following formula
G_{XDCT} = G_{XD} + G_{TB} + G_{QLDA} + G_{TV} + G_{K} + G_{DP} (2.1)
In which:
 G_{XD}: cost of construction;
 G_{TB}: cost of equipment;
 G_{QLDA}: cost of project management;
 G_{TV}: cost of construction investment consultation;
 G_{K}: other costs;
 G_{DP}: contingency cost.
The works construction estimate is aggregated in Table 2.1 of this Appendix.
1. Determining the cost of construction (G_{XD})
The cost of works construction is the total costs of construction of items of main and auxiliary works (except for temporary works for staying and construction operation), the temporary works in service of construction likely to be determined by each content of cost or aggregate the contents of cost by one of the methods guided in Appendix 03 of this Circular.
2. Determining the cost of equipment (G_{TB})
The cost of equipment determined by works or works items including the cost of procurement of works equipment and technological equipment, cost of training and transfer of technology (if any); cost of installation, testing, calibration of equipment and other relevant costs are determined by the following formula:
G_{TB} = G_{MS} + G_{ĐT} + G_{LĐ} (2.2)
In which:
 G_{MS}: cost of procurement of works equipment and technological equipment;
 G_{ĐT}: cost of training and transfer of technology;
 G_{LĐ}: cost of installation, testing, calibration of equipment;
2.1. The cost of procurement of works equipment and technological equipment is determined by the following formula:
(2.3)
In which:
 Q_{i}: Quantity or amount of i^{th} equipment (group of equipment) i^{th} (i = 1÷n);
 M_{i}: price calculated for a unit of quantity or a unit of amount of equipment (group of equipment) i^{th} (i = 1÷n) determined by the following formula:
M_{i} = G_{g} + C_{vc} + C_{I}_{k }+ C_{bq} + T (2.4)
In which:
 G_{g}: Price of equipment at the purchasing place (place of manufacture, fabrication or place of equipment supply in Vietnam) or the price calculated for arrival in the ports of Vietnam (for imported equipment) including the cost of design and supervision of equipment manufacture;
 C_{vc}: Cost of transport of a unit of quantity or a unit of amount of equipment (group of equipment) from the purchasing place or ports of Vietnam transported to the construction site;

 C_{bq}: Cost of maintenance of a unit of quantity or a unit of amount of equipment (group of equipment) at the site;
 T: relevant taxes and fees
For the equipment which does not meet the conditions for price determination by the formula (2.4) mentioned above, it is likely to make estimation on the basis of selection of lowest price between the quotations of the manufacturer or equipment provider (except for the equipment introduced for the first time and being unique on the market) to ensure the satisfaction of requirements for equipment supply for the works or the price of equipment of similar power, technology and origin on the market at the time of calculation or of the works with similar equipment which was or is being implemented. During the determination of cost of construction investment, the consultation contract is responsible for review and evaluation of consistency of equipment price when using the above quotations.
For types of works equipment and technological equipment to be manufactured or processed, the cost is determined on the basis of quantity of equipment to be manufactured or processed and the price of manufacture and processing of one ton (or a calculation unit) in line with nature and type of equipment under the signed contract of production and processing or based on the manufacturer’s quotation of product processing selected by the investor or the price of production and processing of similar equipment of works which were or are being implemented.
2.2. The cost of training and technology transfer is determined by making the estimate depending on the specific features of each project.
2.3. The cost of installation of equipment and cost of testing and equipment calibration is determined by making the estimate like the cost of construction.
The cost of equipment is aggregated in Table 2.2 of this Appendix.

C_{HMC} = (C_{NT} + C_{KKL}) x (1+T) + C_{K} (2.8)
In which:
a) C_{NT}: cost of temporary house at the construction site for stay and construction operation
The cost of temporary house at the construction site for stay and construction operation is the cost to build the temporary house at the construction site or house lease or travel expenses in service of stay and operation of construction of the contractor during the works construction.
The cost of temporary house at the construction site for stay and construction operation is calculated by the percentage of 2% over the cost of construction and installation, testing and calibration of equipment before value added tax for works along the route such as transmission lines, postal communication lines, roads, canals, pipelines and other construction works along the route and equal to 1% for the remaining works.
For other special cases (such as the works with large scale, complexity, at sea, in islands and works using ODA selecting the contractor in the form of international bidding), if the cost items of temporary house at the construction site for stay and construction operation is calculated by the percentage (%) mentioned above is not suiTable, the investor shall, based on the actual conditions, make and approve such cost estimate.
The method of making the estimate for the this cost item is like the method of determining the cost of construction as guided in Appendix 03 of this Circular. The norm of general cost and the predetermined income are calculated by the civil works.
In case of bidding, such cost items must be calculated in the price of package.

c) C_{K}: cost of remaining general items are the cost of movement of specialuse constructional machines and equipment and labor force (with skills under the business management) coming and going out of construction site; cost of traffic safety assurance for construction (if any); cost of restoration of technical infrastructure affected by the works construction (if any); cost of storage and open storage of materials (if any), cost of building of cover house for machine, machine foundation, power and compressed gas and water supply and drainage system at the construction site, installation and dismantlement of some machinery (concrete mixing plant, asphalt mixing plant, overhead crane, tower crane and some other constructional machines and equipment with similar features) and are determined by the method of estimate making or cost estimation.
In case of determination by the estimate, the instructions in the Appendix 03 of this Circular shall apply.
d) T: the prescribed tax rate of VAT.
The estimate of cost of general items is aggregated in Table 2.3 of this Appendix.
6. Determining the contingency cost (G_{DP})
The contingency cost is determined by 02 factors: cost contingency for the generated volume of work and cost contingency for price slippage factor.
The contingency cost is determined by the following formula :
G_{DP} = G_{DP1} + G_{DP2} (2.9)
In which:
 G_{DP}_{1}: contingency cost for the generated volume of work is determined by the following formula:
G_{DP}_{1} = (G_{XD} + G_{TB} + G_{QLDA} + G_{T}_{V} + G_{K}) x k_{ps }(2.10)
 k_{ps} is the contingency coefficient for the generated volume of work. This percentage rate depends on the complexity of works under the project and the geological condition of works where it is being built and the percentage rate is k_{ps} ≤ 5%.

(2.11)
In which:
 T: time of works construction determined by (quarter, year);
 t: ordinal number of capital allocation under the work construction plan (t=1÷T);
 G^{t}_{XDCT}: value of works construction estimate before the contingency cost implemented during the t^{th} period;
 I_{X}_{DCTbq}: construction price index used to calculate the contingency for the price slippage factors determined by the formular 1.7 in the Appendix 01 of this Circular.
± ∆I_{XDCT}: average fluctuation of construction price index by the time of works construction compared with the average price slippage of the unit (quarter, year) calculated and determined on the basis of forecasting of fluctuation trend of factors of price and cost in the region and in the world by the expert experience.

The price of works construction includes the detailed construction unit price of works and the general construction price.
The detailed construction unit price of works is the economic – technical indicator, including all necessary direct cost on materials, labor and constructional machines to finish one volume unit of construction.
The general construction price is the economic – technical indicator, including all necessary direct cost to finish one unit of group of type of constructional activities, structural unit and component unit of works.
The construction unit price is determined based on the market price or determined from the norm of works construction estimate.
I. METHOD OF DETERMINING THE DETAILED WORKS CONSTRUCTION UNIT PRICE
1. Grounds for determining the detailed works construction unit price
 List of constructional activities of works which need the unit price;
 Norm of construction estimate under the List in need of unit price;
 Cost of materials (excluding VAT) transported to the constructional site;
 Cost of works construction labor;
 Cost of machine shift and works constructional equipment
2. Determining the incomplete detailed works construction unit price
2.1. Determining the cost of material (VL)
The cost of material is determined by the following formula:
(4.1)
In which:
 V_{i}: volume of ith material (i=1÷n) calculated for one volume unit of construction;
 : price of one unit of i^{th} material (i=1÷n) determined must be consistent with the technical standards, the prescribed quality of material, requirements for material use of works taking into account the construction site. The price of one unit of i^{th} constructional material is determined as per the announcement of price of constructional material of locality in line with the time of unit price preparation and the market price at the place of works construction.
Where the price of constructional materials as announced by locality is not consistent with the market price level at the place of works construction and the constructional materials not included in the announcement of price of constructional materials of the localities, the price of these constructional materials is determined on the basis of selecting the consistent price between the quotations of the manufacturer or the provider of constructional materials (except for the equipment introduced for the first time and being unique on the market) to ensure the satisfaction of demand for use of materials of works on progress, supply volume, quality standards and technical specification of materials or price reference of types of constructional materials with similar standards and quality which were and are being used in other works.
For the constructional materials which the domestic market does not have and must import them, the price of these materials is determined on the basis of selecting the lowest price between the quotations of the manufacturer or the provider of constructional materials in line with the quality standards and origin of goods.
For the works using the ODA, in case of determining the price of types of material which the domestic market has but must import them in accordance with the provisions in the loan agreement of the donor, the price of imported materials is determined by the import quotation in line with the quality standards, origin of goods and the price level in the region.
Where the price of material has not taken into account the constructional site, the price of material transported to the construction site is determined under the instructions in Section 2.4 of this Appendix.
 K^{vl}: cost calculation coefficient of other materials (if any) compared with total costs of main materials determined in the norm of works construction estimate.
2.2. Determining the cost of labor (NC)
The cost of labor is determined by the following formula:

 M_{i}: waste volume of machine shift of type of i^{th} main constructional machines and equipment (i=1÷n) calculated for one volume unit of construction;
 G_{i}^{mtc}: price of machine shift of i^{th} main constructional machines and equipment (i=1÷n) based on the quotation of constructional machines shift and equipment of works or price of machine leasing determined in the Appendix 06 of this Circular.
 K^{mtc}: cost calculation coefficient of other machine (if any) compared with the total cost of main constructional machines and equipment determined in the norm of works construction estimate.
2.4. Method of determining the cost of materials transported to the construction site (G^{vl})
The price of materials transported to the construction site is determined by the following formula:
G^{vl} = G^{ng} + C^{v}^{/}^{c} + C^{bx} + C^{vcnb} + C^{hh} (4.4)
In which:
 G^{ng}: price of materials at the supply source (price of material on means of transportation);
 C^{v/c}: cost of transportation to the works;
 C^{bx}: cost of loading and unloading (if any);
 C^{vcnb}: cost of transportation within the works (if any).
 C^{hh}: cost of loss from storage at the construction site (if any);
The table of price calculation of material transported to the construction site is aggregated under the instructions in Table 4.1 in which the cost of material transportation to the construction site is determined on the basis of transportation plan (distance, transport road grade, type, load of means of transportation) in line with the conditions for works construction.
A number of types of constructional material are purchased with large amount but the producer or provider does not calculate (the discount) the cost of transport. Therefore, the cost of transport shall not be included in the price of materials transported to the construction site.

Step 2. Determining the work components
The work components represent the steps of work to be performed of each phase based on the design of organization of performance technology line from the preparation to the completion, in line with the condition and measures of performance and range of work performance of constructional activities or constructional structure.
Step 3. Calculating the waste of materials, labor and constructional machines
1. Calculating the waste of materials
1.1. Determining the waste components of materials
The waste components of materials are the materials determined by the design requirements, regulations and standards of construction, technical norms of prescribed design – performance  acceptance and other materials to finish one volume unit of constructional work or constructional structure. The waste components of materials include:
1.1.1. Main materials are the basic materials forming a product unit by the design and have large proportion in material cost.
 The calculation unit is determined in accordance with the regulations in the system of common measurement unit or in kind.
1.1.2. Other materials are the materials forming a product unit by the design and have smaller proportion in material cost.
 The calculation unit is determined by the percentage (%) compared with the cost of main materials in the material cost.
1.2. Calculating the material waste
The material waste is the necessary waste by the design requirements to finish one volume unit constructional activities or constructional structure.
1.2.1. The formula used to calculate the main material waste is as follows:
a) Noncirculating materials

In which:
 Q^{V}: waste of necessary material by design requirement over the norm calculation unit.
 H_{t/}_{c}: percentage of material loss in construction under the instructions in the announced material use norm. For the new materials, the percentage of material loss in construction can be applied by the announced material use norm; by the manufacturer’s standards and instructions; by the actual loss or by expert experience.
b) Circulating materials
The material waste for the construction based on the performance measure design is determined by the performance techniques and a number of circulation by the material use norm announced or calculated in case of not included in the material use norm.
Calculation formula:
VL_{2} = Q^{V}_{LC} x (1 + H_{t}_{/}_{c}) x K_{LC} (5.2)
In which:
 Q^{V}_{LC}: circulating material waste volume
 H_{t/}_{c}: determined as in formula (5.1).
 K_{LC}: material compensation coefficient upon circulation is determined by the material use norm announced by the Ministry of Construction.
+ For the materials with the times of circulation and loss compensation percentage different from the regulations in the announced material use norm, the coefficient K_{LC} is determined by the following formula:
(5.3)
In which:

The coefficients related to the remaining cost items in the cost of construction, including: general cost, predetermined taxable cost, VAT calculated over the cost of materials, labor and constructional machine determined based on the instructions on making the constructional cost estimate issued at the original time and the time of comparison and the type of works.
4.2.2. Price index of works equipment (I_{TB}) is determined by the total of products of average proportion of cost of main equipment procurement, cost of installation, testing and calibration of such main equipment (if any) multiplied by the fluctuation coefficient of the respective costs mentioned above of the selected representative works.
I_{TB} = P_{STB} x K_{STB} + P_{LĐ}_{ }x K_{LĐ} (7.14)
In which:
 P_{S}_{TB}, P_{LĐ}: average proportion of cost of main equipment procurement, cost of installation, testing, calibration of such main equipment (if any) of the selected representative works.
 K_{STB}, K_{LĐ}: fluctuation coefficient of cost of main equipment procurement, of cost of installation, testing, calibration of such main equipment (if any) of the selected representative works.
fluctuation coefficient of cost of main equipment procurement is determined by the ratio between the average cost of equipment procurement at the time of comparision with the original time.
The price of equipment is determined by the method of survey and statistics of price data of the main equipment with large quantity, high price and great fluctuation on the market, or can be determined on the basis of reference to the price slippage of equipment or calculated by the price slippage of equipment manufacture structure.
The main equipment is the one with the large cost proportion in the cost of equipment procurement. Example for the civil construction works: lift system, airconditioning system…. for the industrial construction works: major manufacture technology line, etc.
The fluctuation coefficient of cost of equipment installation, testing and calibration (if any) is determined as for the price index of constructional part.
4.2.3. The price index of other cost (I_{CPK}) is determined by the total products of average proportion of main cost items in the other costs of the representative works multiplied by the fluctuation coefficient of the respective cost items and is determined by the following formula:
(7.15)
In which:
 P_{KMKs}: average proportion of s^{th} main cost items in the total cost of main items of the other costs of the representative works;
 K_{KMKs}: cost fluctuation coefficient of the s^{th} main cost items of the other costs of the representative works;
 e: number of main cost items of the other costs of the representative works;
The main cost items of the other costs of the representative works are the cost items occupying a large proportion of the other costs of the representative works, for example for the civil construction works, the main cost items of the other costs such as the cost of constructional survey, design, preparation for works construction project, management of project,…
For the cost items occupying the proportion 1,5% of the other total costs of the representative works, no calculation is required.
For some other cost items calculated over the cost of construction or cost of equipment, their fluctuation coefficients are equal to the price coefficient of constructional part or the price index of respective equipment.
For some other cost items calculated over the total cost of construction and cost of equipment, their fluctuation coefficients are equal to the average of price index of constructional part and the price index of equipment.
4.3. Xác Determining the price index of works construction
The price index of works construction is determined by the total products of the average proportion of cost of construction, equipment and other costs with the price indexes of part of construction, equipment and the other respective costs of the representative works.
The price index of works construction (I) is calculated by the formula:
I = P_{XD} I_{XD} + P_{TB} I_{TB} + P_{CPK} I_{C}_{PK} (7.16)
In which:
 P_{XD}, P_{TB}, P_{CPK}: average proportion of cost of construction, equipment and other costs of the selected representative works. The total of average proportions mentioned above is equal to 01.
 I_{XD}, I_{TB}, I_{CP}_{K}: price index of part of construction, equipment and the other costs of the representative works.
The method of determining the components of formula (7.16) is as follows:
 The price index of part of construction, equipment and the other costs (I_{XD}, I_{TB}, I_{CPK}) is determined under the instructions at Point 4.2 of this Appendix.
 The average proportion of the cost of construction, equipment and the other costs (P_{XD}, P_{TB}, P_{CPK}) is determined as follows:
The average proportion of the cost of construction (P_{XD}), cost of equipment (P_{TB}), and the other costs (P_{CPK}) is determined by the arithmetic average of proportions of respective cost of construction, of equipment and of other costs of the representative works of the type of works.
The proportion of the cost of construction, cost of equipment and other costs of each representative works is equal to the ratio between the cost of construction, equipment and other costs of such representative works compared with these total costs of the works. The formula for determination is:
(7.17)
(7.18)
(7.19)
In which:
 P_{XD}_{i}, P_{TB}_{i}, P_{CPK}_{i}: proportion of cost of construction, equipment and other costs compared with these total costs of i^{th} representative works;
 G_{XD}_{i}, G_{TB}_{i}, G_{CPK}_{i}: cost of construction, equipment and other costs compared with these total costs of i^{th} representative works;
 G_{XDCT}_{i}:
total costs of construction, equipment and other costs of i^{th} representative works;
The data of cost of construction, equipment and other costs of the selected representative works are determined from the collected statistical data.
