What is Five-without Engineering Assessment?

In the construction inspection industry, "Five-without projects" typically refer to construction projects lacking legal procedures and necessary documents. The purpose of appraising "Five-without projects" is primarily to assess their structural safety and legality, usually involving the completion of relevant procedures or determining the project status in judicial proceedings.

Specific Meaning of "Five-without Projects"

"Five-without projects" usually refer to construction projects lacking the following five aspects:

• No project approval: Failure to complete project approval, verification, or registration procedures as required.

• No planning permit: Failure to obtain a construction land planning permit and a construction engineering planning permit.

• No land certificate: Failure to obtain a legal land use rights certificate.

• No construction permit: Failure to obtain a construction permit (construction application procedures) as required.

• No acceptance: Failure to conduct completion acceptance or failure to pass the acceptance inspection.

How the Construction Inspection Industry Conducts "Five-without Project" Appraisals

"Five-without project" appraisals are usually conducted by qualified construction inspection or building safety appraisal agencies (sometimes including survey and design units). The appraisal process typically includes the following steps:

• Accepting the commission: The owner (property owner) or judicial institution commissions a professional appraisal unit.

• Preliminary preparation: Collecting relevant project information, such as remaining design documents and construction records.

• On-site investigation and testing: Conducting a comprehensive on-site survey and testing of the building's structure, materials, and construction quality, including using ultrasonic and other technical means to assess component quality.

• Determining the testing plan: Developing a detailed testing and experimental plan based on the on-site situation and the client's requirements.

• Data analysis and evaluation: Analyzing the test data and evaluating the safety and functionality of the building based on relevant national construction codes and technical standards.

• Issuing the appraisal report: Providing professional appraisal conclusions and necessary reinforcement and repair suggestions based on the evaluation results.

• Issuing the report: The appraisal agency issues a formal "five-without project" inspection and appraisal report. This report usually has legal effect and can be used in administrative approval or judicial proceedings.

For complex situations involving functional use or judicial appraisals, the appraisal agency may consult with experts in relevant fields, but the final appraisal opinion is still issued by the judicial appraiser of the agency.
