What is the quota for removing concrete jackets: Analysis of hot topics on the Internet in the past 10 days
Recently, with the advancement of urban renewal and infrastructure projects, "what is the quota for dismantling concrete sleeves" has become a hot topic in the engineering field. This article combines the hot data of the entire network in the past 10 days to analyze the relevant content in detail and provide structured data reference.
1. Background analysis of hot topics
According to search data from major platforms, the search volume related to "concrete demolition quota" in the past 10 days has increased by 120% year-on-year, mainly focusing on the following application scenarios:
| Scene classification | Proportion | Typical questions |
|---|---|---|
| Municipal Engineering | 45% | Road reconstruction concrete demolition pricing |
| Building renovation | 32% | Floor slab demolition quota application |
| industrial demolition | 18% | Equipment foundation dismantling measurement |
| other | 5% | Demolition of special structures |
2. Comparison of mainstream quota standards
Currently, the commonly used concrete demolition quotas in China mainly include the following three types of standards:
| Quota name | Applicable areas | Pricing method | Update date |
|---|---|---|---|
| Specification for pricing of bill of quantities for construction projects | Nationwide | Comprehensive unit price | 2021 edition |
| House renovation project budget quota | Provinces and cities | Work material machine method | 2018-2022 |
| Municipal engineering demolition consumption quota | prefecture-level city | market price adjustment | 2020-2023 |
3. Solutions to typical problems
Based on frequent questions from netizens, we have compiled professional answers to three typical questions:
1. Quotas apply for concrete pavement demolition
It is recommended to give priority to the demolition project chapter in the "General Projects" in the first volume of "Municipal Project Consumption Quotas" and select the corresponding subheading according to the thickness (such as code 01010121 within 10cm).
2. Reinforced concrete structure demolition
The component type needs to be distinguished:
- Beams, slabs and columns apply to construction project quotas
- Special quotas for blasting and demolition of large volumes of concrete
- Steel content >1% needs to be multiplied by a factor of 1.2
3. Pricing for removal of demolition waste
Note that it contains three parts:
① On-site loading (by cubic meter)
② Transportation (ton-kilometres)
③ Accommodation and treatment (standards vary from region to region)
4. Latest industry trends
Recently, many places have issued new regulations, which are worth paying attention to:
| area | Key points of the new regulations | Execution time |
|---|---|---|
| Guangdong Province | Added quota for dismantling of prefabricated structures | 2023.9.1 |
| Zhejiang Province | Adjustment of construction waste removal unit price | 2023.8.15 |
| Beijing | Release of supplementary quota for silent demolition | 2023.9.5 |
5. Operation suggestions
1. Give priority to using the latest quota version in the project location
2. Make on-site survey records before dismantling (it is recommended to retain image data)
3. For complex projects, it is recommended to prepare a special demolition plan
4. Pay attention to the supplementary quota issued by the local housing and construction department
6. Dispute handling
When a dispute arises about quota application, you can refer to the following handling process:
① Check the general description of quotas
② Compare similar projects
③ Consult the quota station
④ Apply for on-site survey
⑤ Negotiate according to the contract
Through the above structured data analysis, we hope to help engineering practitioners accurately apply concrete demolition quotas. It is recommended to flexibly apply it in combination with project characteristics and local regulations in actual operations, and consult professional estimators when necessary.
