Investors shall take responsibility for their decisions. If to be-adjusted total investment capital amounts are higher than approved total investment capital amounts investors shall report such to investment deciders for the latter’s permission before effecting the adjustment.

For works funded with the State-guaranteed credit capital, state development investment credit capital and investment capital of other sources of the State, investors shall themselves decide on adjustment of total investment capital amounts and take responsibility for their decisions.

Differences between adjusted total investment capital amounts and approved ones must be evaluated according to the provisions of Article 6 of Decree No. 99/2007/ND-CP.

1.1.3. Project management expenses shall be determined by investors for performance of project management jobs. For small and simple projects each capitalized at less than VND 1 billion, if investors do not set up project management units but use their professional units in managing the projects, they shall use the project management funding source to finance project management activities and give overtime pays to part-time project management staff according to current regulations.

...

...

...

If project management units are capable of performing some construction investment consultancy jobs, they may enjoy expenses for performance of these jobs.

APPENDIX 1

...

...

...

Total investment capital amounts of work construction investment projects are calculated and determined at the stage of formulation of work construction investment projects or elaboration of econo-technical reports. Total investment capital amounts shall be determined by one of the following methods:

1. Method of determination according to basic designs of projects

The total investment capital amount of a work construction investment project is calculated according to the following formula:

V = GXD + GGPMB + GQLDA + GTV + GK + GDP (1.1)

In which:

+ V: Total investment capital amount of the work construction investment project.

+ GXD: Construction expenses of the project.

+ GTB: Equipment expenses of the project.

+ GGPMB: Ground clearance compensation and resettlement expenses.

...

...

...

+ GTV: Construction investment consultancy expenses.

+ GK: Other expenses of the project.

+ GDP: Contingency expenses.

1.1. Determination of construction expenditure of projects

The construction expenditure of a project (GXD) is the total of construction expenses of works and work items under the project and calculated according to the following formula:

GXD + GXDCT1 + GXDCT2 + ... + GXDCTn       (1.2)

In which: n is the number of works and work items under the project.

Construction expenses of a work or work item under the project arc calculated as follows:

      (1.3)

...

...

...

+ m: Number of principal construction jobs/main structural parts of the work or work item under the project.

+ j: Ordinal number of principal construction job/main structural part of the work or work item under the project (j = 1÷ m).

+ QXDj: Volume of principal construction job No. j/main structural part No. j of the work or work item under the project.

+ Zj: Unit price of principal construction job No. j/unit price of main structural part No. j of the work. The unit price may be a complete detailed construction unit price or complete consolidated construction unit price (consisting of direct expenses, general expenses and pre-determined taxable income), or a complete unit price of each structural part of the work. If Zj is an incomplete construction unit price, expenses for construction of the work or work item are summed up according to Table 2.2 in Appendix 2 to this Circular.

+ GQXDK: Construction expenses for other remaining jobs/other remaining structural parts of the work or work item, which are approximated in a percentage (%) of the total construction expenses of principal construction jobs/total construction expenses of main structural parts of the work or work item.

The percentage (%) of construction expenses of other remaining jobs/other remaining structural parts of the work or work item shall be approximated depending on each type of construction work.

+ TGTGT-XD: Value-added tax rate prescribed for construction activities.

1.2. Determination of equipment expenditure of projects

Depending on specific conditions of a project and available information and data, one of the following methods may be used to determine equipment expenses of the project.

...

...

...

Equipment expenses of works are determined by the method of estimation guided in Section 2, Appendix 2 to this Circular.

b/ If the project has information on offer prices of complete equipment and technological chain (inclusive of expenses specified in Item 1.1.2, Part II of this Circular) from equipment manufacturers or suppliers, equipment expenditure (GTB) of the project may be quoted prices or offer prices of such complete equipment.

c/ If the project has only general information or data on the capacity and technical specifications of technological chain and equipment, equipment expenditure may be determined according to the equipment expense ratio for a unit of production or service capacity of works, and the formula (1.10) in Part II of this Appendix.

1.3. Determination of ground clearance compensation and resettlement expenditure

Ground clearance compensation and resettlement expenditure (GGPMB) of a project is determined according to the volume of compensation and resettlement work of the project and the State’s current regulations on compensation and resettlement prices in the locality where works are constructed, which are approved or promulgated by competent authorities.

1.4. Determination of project management expenses, construction investment consultancy expenses and other expenses of projects

Project management expenses (GQLDA), construction investment consultancy expenses (GTV) and other expenses (GK) of a project are determined by the method of estimation or calculated according to percentage norms (%) (see Sections 3, 4 and 5, Appendix 2 of this Circular). Otherwise, the total of these expenses (exclusive of loan interests during the time of project execution and initial working capital) may be approximated at 10÷15% of the total of construction expenditure and equipment expenditure of the project.

Initial working capital (VLD) (for production and business projects) and loan interest during the time of project execution (LVay) (for projects using loan capital) may be determined depending on specific conditions, execution progress and capital distribution plan of each project.

1.5. Determination of contingency expenses of projects

...

...

...

Contingency expenses are calculated according to the following formula:

GDP = (GXD+GTB+GGPMB+GQLDA+GTV+GK) x 10%                (1.4)

For projects with an execution duration of more than 2 years, contingency expenses are determined based on two factors of arising work volume and inflation and according to the following formula:

APPENDIX 3

METHOD OF FORMULATING WORK CONSTRUCTION NORMS
(Attached to the Construction Ministry’s Circular No. 05/2007/TT-BXD of July 25, 2007)

I. METHOD OF FORMULATING NEW CONSTRUCTION NORMS OF WORKS

New construction norms of a work are formulated in the following order:

Step 1: Drawing up a list of the work’s new construction jobs or structures which are not on the announced list of construction norms.

The list of new construction jobs or structures must clearly state the unit of volume calculation and requirements of construction techniques, conditions and measures of the work.

...

...

...

The composition of construction jobs must clearly state steps to be performed at each stage under the design of the technological chain for construction from commencement to completion, which are suitable to construction conditions and measures and scope of performance of jobs of the work.

Step 3: Calculating and determining consumption of materials, labor and construction machines

A. METHODS OF CALCULATION :

Consumption norms of new construction jobs are calculated by one of the following three methods:

Method 1: Calculation according to technical parameters in the technological chain.

- Material consumption is determined according to the design and work construction conditions and measures or announced material use norms.

- Labor consumption is determined according to the labor use in the technological chain and suitable to work construction conditions and measures, or calculated according to announced labor norms.

- Construction machine consumption is determined according to technical parameters of each machine in the chain or announced construction machine performance norms, taking into account efficiency brought about by the combined use of construction machines in the chain.

Method 2: Calculation according to statistical and analytical figures.

...

...

...

- From consumed quantities of materials, labor and construction machines for performance of a construction volume in one or more than one cycle of an ongoing work.

- From the consumption of materials, labor use and construction machine performance already calculated for similar works.

- From figures announced according to experience of experts or professional organizations.

Method 3: Calculation according to field surveys

To calculate and determine consumption levels according to design documents, field survey figures of works (construction time, location and volume in one or more than one cycle), taking into account announced use norms of materials, labor and machine performance.

- Material consumption is calculated according to field survey figures and compared with technical design, regulations and standards.

- Labor consumption is calculated according to the number of laborers at each stage of the production chain and total number of laborers in the whole chain, and regulations on labor use.

- Construction machine consumption is calculated according to survey figures on performance of each machine and efficiency brought about by the combined use of construction machines in the same chain, and regulations on technical performance of machines.

B. CONTENTS OF CALCULATION OF CONSUMPTION ELEMENTS

...

...

...

- Principal (main) materials: sand, stone, cement, brick, roofing tile, iron, steel, etc. in jobs of preparing concrete, laying bricks, framing reinforced concrete or prefabricating structures are high-value materials accounting for large proportions in a volume or structure unit. For these materials, consumption norm levels are prescribed in kind and calculated in common units of measurement.

- Other (auxiliary) materials: soap, lubricants, cleaning cloths, etc., which are of small value and hard to be quantified and account for small proportions in a volume or structure unit. For these materials, consumption norm levels are prescribed in percentages of expenses for main materials.

Material consumption norms are determined on the basis of announced material norms or calculated by one of the aforesaid three methods.

B.1. 1. Calculation of consumption of principal materials

The general formula for determining the material consumption norm (VL) in construction norms is as follows:

VL = (QV x Khh +  x KLC) x  x Ktd                  (3.1)

In which:

+ QV: quantity of materials used for each construction job component in the norm (except for recyclable materials), which is calculated by one of the aforesaid three methods.

The quantities of materials constituting products under designs arc determined according to design standards. For example, quantities of macadam, cement and water consumed to make concrete graded according to mortar grade are calculated according to Vietnam construction standards or standards of construction works.

...

...

...

+ : quantity of recycled materials (framework, scaffolding, operating bridge, etc.) used for each construction job component in the norm, which is calculated by one of the aforesaid three methods.

+ : coefficient for conversion of the units of calculation for materials according to calculations, construction reality or experience into those in construction norms.

+ Khh: percentage norm of allowable material wastage in construction:

Khh = 1 + Ht/c                     (3.2)

Ht/c: material wastage in construction according to announced material norms, surveys or practical conditions of similar works or experience of experts or professional organizations, for materials not subject to any norms.

Wastage prescribed for loose materials, semi-finished materials (building mortar, concrete mortar) and structural elements (precast piles and beams).

+ KLC: recycling coefficient of materials that need to be recycled prescribed in material use norms. For non-recyclable materials. KLC is 1. For recyclable materials. KLC is smaller than 1.

The recycling coefficient of a recyclable material is calculated according to the following formula:

                  (3.3)

...

...

...

- h: wastage compensation rate from the second time on.

- n: number of times of use of recyclable materials (n>1).

+ Ktd: time use coefficient depending on work construction progress, which reflects irregular or maximal utilization of materials to complete a construction job according to set schedule. This coefficient is applicable only to recyclable materials, for example: utilization of scaffolding, forms, props, etc.

When a construction solution is used only once or for many times, this coefficient may be added to suit work construction conditions. This coefficient is calculated according to construction progress or solution or experience of concerned professional organizations.

B.1.2. Calculation of consumption of other materials

Consumption of other (auxiliary) materials is subject to prescribed percentages of the total expenses for main materials quantified in construction norms and determined for different kinds of construction jobs according to experience of consultants or norms of similar works.

B.2. Calculation of labor consumption norm

Labor consumption norm in construction norms is determined based on the announced (working) labor norm, or calculated by one of the aforesaid three methods.

- The unit of calculation of the basic labor norm is working hour.

...

...

...

                                        (3.4)

In which:

+ : basic labor norm, which is the consumption level of labor directly used for construction for a unit of calculation of a specific construction job volume or structure.

+ Kcdd: coefficient for conversion of construction norms.

This coefficient is calculated based on construction norms converted from working norms or on experience of experts.

Depending on job groups and single, or mixed type of machine assembly, the value of this coefficient usually varies between 1.05÷1.3 for different construction jobs, technical requirements and specific construction conditions.

+ KVcd: coefficient for conversion of units of calculation from those in construction reality or experience into estimated norms.

+ 1/8: coefficient for conversion of working hour norm into workday norm.

B.3. Calculation of construction machine consumption norm

...

...

...

The unit of calculation of the basic norm of construction machine performance is machine hour or machine shift.

B.3.1. Calculation of consumption of principal construction machines

The general formula for determining the consumption norm of a construction machine and equipment shift is as follows:

                                    (3.5)

In which:

+ QCM: norm of construction performance of one machine shift determined by one of the aforesaid methods.

+ Kcdd: coefficient for conversion of construction norms.

This coefficient is calculated based on construction norms converted from working norms or on experience of experts.

Depending on job groups and single or mixed type of machine assembly, the value of this coefficient usually varies between 1.05÷1.3 for different construction jobs, technical requirements and specific construction conditions.

...

...

...

+ Kcs: performance utilization coefficient, which reflects the utilization of performance of a machine assembly in a combined chain. This coefficient is calculated according to the performance of construction machines in each working step and appropriately adjusted when machines of the poorest performance are used in the chain.

B.3.2. Calculation of consumption of other construction machines and equipment

Consumption of auxiliary construction machines and equipment is subject to norms in percentages of the total expenses for main machines quantified in construction norms and determined for different kinds of construction jobs according to experience of consultants or norms of similar works.

Step 4: Formulation of norm items on the basis of summing up material, labor and construction machine consumptions

To gather norm items on the basis of summing up material, labor and construction consumption breakdowns.

A norm item consists of two parts:

Composition of jobs, which clearly and fully specifies working steps in the order from the initial preparation for to the completion of a construction job or structure, including also specific construction conditions and solutions.

- Table of norms of consumption breakdowns, which clearly states names and describes categories and specifications of principal materials used in a construction job or structure, and other auxiliary materials: kinds of workers: average grade of construction workers; names, types and capacity of principal machines and equipment and some other machines and equipment in the construction technological chain for accomplishment or completion of a construction job or structure.

In the table of norms, the consumption of principal materials is calculated in kind while that of auxiliary materials is calculated in percentages of expenses for principal materials. Labor consumption is calculated in workdays regardless of grades of workers but according to the average grade of construction w orkcrs. The consumption of principal machines and equipment is calculated in number of machine shifts while that of other (auxiliary) machines is calculated in percentages of expenses for principal machines and equipment.

...

...

...

II. ADJUSTMENT OF MATERIAL, LABOR AND CONSTRUCTION MACHINE CONSUMPTION ELEMENTS UPON APPLICATION OF ANNOUNCED CONSTRUCTION NORMS

Upon application of announced construction norms to a work, if some elements remain inappropriate to the provisions of these norms due to construction conditions and solutions and technical requirements of the work, relevant material, labor and construction machine elements should be adjusted to suit the work.

II.1. Grounds for adjustment

- Construction conditions and solutions of works.

- Technical and construction schedule requirements of works.

II.2. Methods of adjustment

11.2.1. Adjustment of material consumption

- For consumption of materials constituting products under designs, designing regulations and standards of works are bases for calculation and adjustment.

- For materials used in construction solutions, elements in announced norms shall be adjusted according to consumption calculations based on designs of construction solutions or experience of experts and professional organizations.

...

...

...

Increase or decrease in the labor element in announced norms and consumption calculations under conditions of construction organization or according to experience of experts and professional organizations.

II.2.3. Adjustment of construction machine consumption

- In case of change due to construction conditions (complex or simple terrains, quick or slow progress of works), calculations for increase or decrease of the norm value shall be made under construction-organizing conditions or according to experience of experts and professional organizations.

- In case of change due to increase or decrease of construction machine capacity, adjustment shall be made on the principle that an increase in capacity leads to a decrease in value and vice versa.
