Information
Description
Excerpted from the "New Blasting Project Consumption Quota" edited by China Engineering Blasting Association GYD-102-2008 Blasting engineering belongs to special technical engineering, in addition to the implementation of the "Building and Installation Engineering Cost Project Components" issued by the Ministry of Construction (Ministry of Construction, No. 206, 2003) In addition to the measures specified in the document, the projects that should be included in the measures are: blasting engineering design, safety assessment, supervision and monitoring.
The blasting safety protection measures are as follows:
|
category |

Billing method: According to the approved construction plan and protective means, refer to the methods generally used and the materials used in the project site, and calculate according to the actual situation.
Test blasting engineering
According to the test plan and the scale of the test blasting project, the design and construction costs will be calculated separately.
Other measures for blasting engineering
According to the particularity of the blasting project, the following blasting measures should also be included in the preparation of the total cost of the blasting project:
1 Blasting engineering design and assessment fee. The blasting design shall be undertaken by the unit with design qualification. The general open blasting shall be charged according to the direct cost of the blasting project of 3% to 5%; the design of the demolition blasting shall be detailed for the building structure, the materials used, the surrounding environment and the facilities that must be protected. In the investigation, the billing is calculated within 10% of the direct cost of the blasting project, and the Class A project is multiplied by a factor of 1.1 according to the level specified in the blasting safety regulations. The design of chamber blasting requires topographic survey, geological sketching, section and resistance line retesting, etc. The billing is calculated within 10% of the direct cost of the blasting project.
2 Blasting safety assessment fee. The blasting project approval unit entrusts the unit or personnel with the corresponding qualification level to carry out the safety assessment of the blasting project. The fee collection principle is based on the cost that can support the evaluation. The charging standard is based on the direct cost of the blasting project. The evaluation fee of direct cost less than 100,000 yuan is calculated at 5%; the 10,000-100 million yuan is 5%. 3% of the calculation; 100 to 5 million yuan to 3%. 1% of the project, the project of more than 5 million yuan, according to the nature of the project, the difficulty rate, the rate is not more than 1%. The difficulty factor for the increase of the fee for the Class A blasting project specified in the blasting safety regulations is 1.1.
3 Special supervision fee for blasting project. The project supervision shall be carried out by the blasting supervision unit with the corresponding level of qualification. The project construction unit employs and signs the project supervision contract. The billing standard is calculated based on the direct cost of the blasting project. The project within 100,000 yuan is calculated to be more than 10%, the project with 10 to 1 million yuan is calculated from 10% to 5%, and the project with 100 to 5 million yuan is calculated as 5 to 5%. 3%; projects with an investment of more than 5 million yuan are calculated to be less than 3%. The difficulty factor for the increase of the fee for the Class A blasting project specified in the blasting safety regulations is 1.1.
