Consulting fee for basic business of engineering cost = billing base × unit price of measurement benchmark × service content coefficient × drawing efficiency reduction coefficient × entrusted scope coefficient × time limit adjustment coefficient × change adjustment coefficient+daily work fee.
The project amount includes unit cost and daywork cost.
The unit price charging is calculated according to the accumulation of each specialty, and the charging base of steel structure is the tonnage of steel structure; Due to the existence of entrusted steel structure list compilation and valuation, service content coefficient is also needed.
Daily working cost = number of working days on site × unit price.
No change is considered when publishing business, and the change conditions will be started after publishing. The final charge price is project amount × change adjustment coefficient.
(A) the determination of the billing base
1, ordinary buildings, single basement indoor engineering take the construction area as the billing base, and the calculation rules shall be implemented in GB/T 50353-20 13 Code for Calculation of Construction Area of Building Engineering;
2. The indoor works of villas and Xiaoyanglou are based on the number of single buildings, and the townhouses are calculated as one unit or two townhouses;
3. Outdoor works of various building types shall be subject to the total project area.
(2) The unit price of measurement benchmark is shown in the Standard Table for Measurement and Charging of Civil Construction Projects.
(3) service content coefficient
1, the measurement is entrusted separately, and the service content coefficient is 1.
2. At the same time, the content coefficient of entrusted document preparation service is 1. 15, the content coefficient of entrusted pricing service is 1. 15, and the content coefficient of entrusted document preparation and pricing service is 1.30.
3. The compilation of the independent entrustment list is charged according to item 4, and the independent entrustment valuation is charged according to item.
(4) extracting invalid coefficients
1, and the efficiency reduction adjustment coefficient of existing CAD drawings is 1.
2. The adjustment coefficient of drawing efficiency reduction without CAD is 2.
(V) Entrusted range coefficient
1, the whole project is entrusted (the smallest unit project), and the entrusted scope coefficient is 1.
2. According to the entrustment of house type, standard floor and model room, the entrustment range coefficient is 3.
3. When civil engineering calculation is entrusted separately (excluding reinforcement calculation), the entrusted range coefficient is 1.2.
4. When the entrusted scope includes design changes not reflected in the construction (completion) drawings, the entrusted scope coefficient is 1.5.
(6) Time limit for a project adjustment coefficient
1, standard duration
Standard time limit for a project ST calculation model:
Parameter: building area x (unit: 10,000 square meters)
Engineering survey including drawings: ST including drawings = 2.2 * sqrt(x)+2, rounded.
Engineering measurement without drawing: without drawing ST = with drawing ST * 1.4, rounded.
Separate list or estimate: st estimate =ST including drawings * 0.8, rounded.
Among them, the standard construction period in the above table is applicable to the steel structure project according to the actual construction area, and the standard construction period in the above table is applicable to the converted construction area of each villa and Xiaoyanglou according to 6,543,800 square meters.
2, time limit for a project adjustment coefficient
Calculation model of construction period adjustment coefficient a;
T= required duration/standard duration
A=0.25 * T^-2.322 + 0.75
(7) Change the adjustment coefficient.
Due to drawing changes, scope adjustment, interface division, new requirements and other reasons. , resulting in repeated work such as model modification or re-modeling, list modification and pricing, and the extra work undertaken is charged according to the following table: the adjustment coefficient is selected according to the cumulative result of the extra work after repeated modification.
Calculation model of adjustment coefficient m for drawing change;
When x is less than 10, M= 1.
When x is greater than or equal to 10, m = 0.085 * sqrt (x-10)+1.
(8) Daily expenses
If the consultant is required to undertake on-site inspection or other work that cannot be charged according to this standard, the daily work unit price, travel expenses and accommodation expenses shall be calculated according to the facts.
Description and explanation
Civil engineering measurement does not include steel structure engineering, if the scope of entrustment includes steel structure measurement and benchmark unit price calculation.
Civil engineering survey includes architectural drawing decoration practice table of general decoration engineering. If the decoration drawings designed separately implement the corresponding standards of architectural decoration engineering, they will be charged separately.
Luxury decoration refers to the project designed according to the decoration standards of hotels above four stars.
Fire engineering refers to indoor fire hydrant system, fire sprinkler system, smoke control system, gas foam fire extinguishing system, automatic fire alarm and fire linkage system.
Intelligent engineering refers to integrated wiring system, security technology prevention system, building equipment monitoring system, broadcast conference system, background music system, intelligent integrated system, etc.
Outdoor facilities refer to roads, hydropower ditches, squares, parking lots, site hardening, slope support, etc.
Accessory buildings and outdoor environment refer to carports, fences, gates, retaining walls, greening, landscapes, etc.
Small buildings refer to projects with a building area less than 1000_.
