According to the different nature of construction projects, construction project supervision and related service charges are subject to government-guided prices or market-regulated prices respectively. The supervision fee for the construction stage of a construction project that must be supervised according to law shall be subject to government guidance price; Supervision fees in other construction stages and supervision and related service fees in other stages shall be subject to market adjustment prices. The benchmark price of supervision fee in the construction stage of the construction project subject to government guidance price is calculated according to the construction project supervision and related service standards, with a floating range of 20%. The employer and the supervisor shall, according to the actual situation of the construction project, negotiate and determine the amount of expenses within the prescribed floating range. Construction project supervision and related service fees shall be subject to market adjustment price, which shall be determined by the employer and the supervisor through consultation. If the construction supervision service of a construction project is undertaken by more than two supervision units, each supervision unit shall calculate the construction supervision service fee according to the proportion of the workload of the construction supervision service. If the Employer entrusts one of the supervisors to be responsible for the construction supervision service of the construction project, the supervisor shall charge the Employer the overall coordination fee according to 4% ~ 6% of the total supervision service fee of each supervisor.

The construction supervision service fee is calculated according to the following formula:

(1) construction supervision service fee = benchmark price of construction supervision service fee × (1 floating range value)

(2) benchmark price of engineering supervision service fee = benchmark price of engineering supervision service fee × professional adjustment coefficient × engineering complexity adjustment coefficient × elevation adjustment coefficient.

The adjustment coefficient of engineering complexity is a coefficient to adjust the complexity and workload difference of construction supervision of the same professional construction project. The complexity of the project is divided into three levels: general, complex and complex, and the adjustment coefficient is: general (1 level) 0.85; More complex (1 1 level)1.0; Complex (IIl level) 1. 15. When calculating the construction supervision service fee, the complexity of the project is determined in the table of engineering complexity in the corresponding chapter.

Legal basis: building law

Article 15

The contracting unit and the contracting unit of a construction project shall conclude a written contract according to law to clarify the rights and obligations of both parties. Contractors and contractors shall fully perform their contractual obligations. Those who fail to perform their obligations in accordance with the contract shall bear the liability for breach of contract according to law.
