According to the percentage of investment in construction projects. This method is based on the size of the project and the complexity of the entrusted supervision work, and is calculated according to a certain proportion of the construction project investment. Generally speaking, the larger the project scale, the more construction investment and the smaller the proportion of supervision fees.
This method is simple and easy to be accepted by owners and engineering supervision enterprises, and it is also the main form for the state to formulate supervision fee standards. The key to adopt this method is to determine the base and proportion of supervision fee. The estimation (budget) of new construction, reconstruction, expansion projects and large-scale technical transformation projects is the basis of the preliminary calculation of supervision fees.
When the project is settled, it will be adjusted according to the actual project investment. Of course, the project budget (budget), as the base for calculating the supervision fee, is limited to the part of the project entrusted for supervision.
Expand the calculation method of data salary plus a certain proportion of other expenses. This method is to multiply the actual salary of the supervisor of the project supervision institution by a coefficient. This coefficient includes due indirect costs and taxes, profits, etc. Except the salary of the supervisor, all other direct expenses shall be paid by the owner alone.
According to the service time agreed in the entrusted supervision contract (the unit of calculation time can be hours, working days or months), the total supervision cost is calculated according to the supervision service fee per unit time. The supervision service fee per unit time is generally based on the basic salary of the employees of the engineering supervision enterprise, plus a certain management fee and profit (pre-tax profit).
When this method is adopted, the travel expenses, work letter electricity expenses, data expenses, test and detection expenses and transportation expenses of the supervisor shall be paid separately by the owner. Time-based payment method is mainly suitable for temporary and short-term supervision business, or it is not suitable for other methods such as engineering estimation (pre-calculation) percentage to calculate supervision fees.
