- 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.

- 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_Vayt: cost of loan interest of investment capital carried out as planned in t^th year;

- I_XDCTbq: 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_CT-SXD           (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.

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_Tti: 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_Tti: 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_Tti >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_Tti <>. In case of deduction, C_Tti­ 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

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 pre-determined income are calculated by the civil works.

In case of bidding, such cost items must be calculated in the price of package.

b) C_KKL: costs of work of general items but the volume from design cannot be determined including: cost of labor safety and environmental protection for the employees on the construction site and the ambient setting; cost of contractor’s material testing; cost of movement of employees within construction site; cost of irregular pumping and dredging are calculated by the percentage (%) over the cost of construction and cost of installation, testing, calibration of equipment before value added tax specified in Table 2.4 of this Appendix.
