How to conduct the review of engineering design drawings? The review of engineering design drawings is a crucial step in ensuring the quality, compliance, and feasibility of the designs. Its core purpose is to identify issues in the designs through systematic checks and to propose improvements. For engineering designers, understanding the basic processes, requirements, and principles of drawing review is of great help in avoiding design risks and improving design capabilities. I. Basic Process of Drawing Review: A review team composed of experts from various specialties (architecture, structure, mechanical and electrical engineering, etc.) is formed, with clear divisions of responsibilities ； Review the submitted complete design documents (construction drawings, calculation reports, regulatory references, etc.), contract requirements, site conditions, and approval documents. →→→Formal review, including checking the drawing catalog, the completeness of signatures (qualification of the design firm, signatures of registered engineers), and the clarity of the drawings. →→→Preliminary compliance check to verify whether the requirements for submission are met (such as whether all the special drawings related to fire protection and civil air defense are available). →→→Professional in-depth review, by specialty (for the architecture specialty, this involves aspects such as overall layout, fire compartmentation, evacuation routes, and accessibility design) ； The structural engineering field focuses on load values, seismic design measures, and the rationality of foundation design, among other things ； The mechanical and electrical engineering field focuses on review and verification of aspects such as pipeline integration, equipment selection, and energy-saving measures. →→→Cross-issue verification, with professional coordination to address communication issues related to intersections, such as pipeline collisions and conflicts in building and structural elevations. →→→Issue feedback, categorize and label it, and grade it by severity, such as \"severe violation\" or \"minor issue\", etc. →→→A \"Review Opinion\" is issued, requiring the design unit to respond to each point and submit revised drawings. →→→Review: Conduct a closed-loop inspection of previous issues to ensure nothing is overlooked. After approval, affix the inspection pass stamp and submit it to the competent authority for record-keeping. II. Basic requirements for drawing review: Strictly adhere to **standards, local regulations, and industry guidelines, especially those that are mandatory, such as the \"Mandatory Provisions of Engineering Construction Standards\". Policy compliance: It meets the requirements of policies regarding green buildings and prefabricated buildings. Systematic review: It should cover all specialties, avoiding a focus on just one specialty; a comprehensive assessment of the coordination between various systems is necessary, such as checking for any conflicts between mechanical and electrical pipelines and the openings reserved in the structure. Life-cycle considerations: Taking into account construction feasibility and operational convenience, such as whether space is reserved for equipment maintenance and whether the transformer capacity meets the expected requirements. Zero tolerance for safety hazards: Focus on reviewing key safety aspects such as structural safety and fire evacuation. Feasibility verification: Construction suitability, checking whether the design details meet the requirements for construction, such as whether detailed drawings are provided for complex joints. Matching of materials and processes: Avoid using materials that have been phased out from the market or unconventional processes; it is recommended to use currently established materials and processes, while new materials and processes should be employed with caution. Rigorous verification: ensuring data consistency, checking the key parameters in drawings and calculation sheets, verifying the completeness of annotations; dimensions, elevations, legends, etc. are clearly marked without ambiguity, thereby reducing the risk of misinterpretation on site. III. Basic Principles of Drawing Review 1. When reviewing construction drawings, it is necessary to rely on specific names and article numbers of the laws, regulations, and **local engineering construction standards that have been violated; personal opinions should not be used as a basis for such review. Note: **Nor should the standard drawings at various local levels be used as a basis for the review of construction drawings. 2. The construction drawings shall be prepared in accordance with the latest valid version of the relevant codes at that time. If the construction review is not carried out in a timely manner after the completion of the construction drawings, but a new version of the codes has already come into effect by the time of the review, such cases shall be handled as indicated in the table below:
