Civil air defense project supervision rules txt1The following is an example of the civil air defense project supervision details:
* * I. Professional Engineering Characteristics **
1. * * Basic information of the project **
- The name and location of the project shall be specified, and the relevant units of the project construction (construction, survey, design, supervision, contractor, etc.) shall be listed. The contract period, cost, building classification, fire resistance grade, earthquake fortification intensity, roof waterproof grade, basement related grade, building design service life and safety grade shall be indicated.
- The relevant indicators of the civil air defense project, such as the construction area, the actual construction area, the number and type of protective units (such as the nuclear six, six, Class A, Class II personnel shelter), the number of anti-explosion units, the use area, the shelter area, the number of people, the usual function, the number and width of evacuation exits, and various protective engineering facilities (air intake, exhaust vent, etc.) required by the civil air defense design were described.
2. * * Engineering characteristics and requirements **
- The characteristics of civil air defense projects were different from ordinary civil buildings, such as the special requirements in terms of structure and protection functions.
* * II. Establishment basis **
1. Civil air defense basic structure design drawings, drawings review minutes, design changes, etc.
2. Construction contract and supplementary agreement.
3. Supervision contract.
4. The relevant codes, such as the Code for Fire Protection of Civil Air Defense Works (GB50098 - 2009), Code for Design of Civil Air Defense Basements (CB50038 - 2005), Code for Design of Air Defense Basements (FK01 - 02), 2007 edition, Code for Design of Civil Air Defense Works Against Chemistry (RFJ013 - 2010), as well as the approved construction organization design and construction plan, etc.
* * III. Supervision Work Flow **
1. * * Civil air defense basic engineering quality control process **
- It includes the inspection of the preparation work before the construction of the foundation project (such as the qualification of the construction unit, the construction plan, etc.), the quality control points during the construction process (such as the quality inspection of the foundation treatment, foundation reinforcement, template, concrete construction, etc.), and the acceptance process after the completion of the construction (such as the organization of the acceptance of the foundation project, the implementation of the acceptance standards, etc.).
2. * * Quality control process of reinforced concrete works **
- For the reinforcement project, the whole process should be monitored from the entrance inspection (type, specifications, quality certification documents, etc.), processing and manufacturing (such as hooks, bending length, etc.), field installation (spacing, anchor length, etc.). For the concrete project, it should include the quality control of raw materials (cement, sand, stone, adjectives, etc.), the review of the mix ratio design, the on-site supervision of the concrete pouring process (vibration, maintenance, etc.), and the production and testing of concrete test blocks.
3. * * Material approval procedure **
- A strict material approval process shall be established. The brand, specifications, model and other information submitted by the construction unit shall be reviewed by the supervising engineer. If necessary, witness, sample and inspection shall be carried out. Only the materials that pass the inspection can be used for construction.
4. * * Concealed Works Inspection and Verification Program **
- After the construction of the concealed works is completed, the construction unit shall pass the self-inspection and fill in the acceptance record of the concealed works, and report to the supervision unit for inspection. The supervising engineer shall carry out on-site inspection on the concealed works, focusing on the concealment of the steel bars (quantity, specifications, location, etc.) and the concealment of the waterproof works (waterproof layer construction quality, joint treatment, etc.). Only after the requirements are met can the next process of construction be carried out.
* * IV. Key Points of Supervision Work **
1. * * Civil engineering **
- If the bottom plate is a beam slab and the top elevation of the beam slab is consistent, the relevant construction points of the slab, such as the position relationship between the beam reinforcement and the slab reinforcement, must be paid attention to during the binding of the reinforcement, and the smoothness and density of the slab must be ensured during the pouring of concrete. At the same time, it was necessary to pay attention to other special requirements of the civil engineering part of the civil air defense project, such as the thickness and strength of the wall, the installation accuracy of the door frame wall such as the protective door and the airtight door (straightness, smoothness, etc.), and the structural structure related to the protective function (such as the reservation of the sealing part in the face of battle, etc.).
2. * * Other parts (such as installation works)**
- For the ventilation, water supply and drainage, electrical and other installation works in the civil air defense project, the supervision work includes whether the selection of equipment and pipes meets the requirements of the civil air defense design.(For example, the protection ability of ventilation equipment, the pressure resistance of water supply and drainage pipes, etc.), the accuracy of equipment installation (for example, the location of ventilation holes and drainage holes, etc.), as well as the adjustment of various systems (for example, the air volume and wind pressure of the ventilation system, the water test of the water supply and drainage system, etc.), to ensure that each system could normally play its protective function during wartime.
* * V. Methods and measures for supervision work **
1. * * Supervision Method **
- Patrol inspection, standing by, parallel inspection, and other methods were used. Patrol inspection is a comprehensive regular or irregular inspection of the construction site to find problems in time; on-site supervision is to supervise key parts and key processes (such as concrete pouring, waterproof construction, etc.); parallel inspection is to use the supervision unit's own testing equipment and personnel to independently test the quality of the project and compare it with the self-inspection data of the construction unit.
2. * * Supervision measures **
- Quality control measures: establish a quality management system, such as quality acceptance system, quality problem correction system, etc., to carry out the whole process and comprehensive control of the project quality. For the quality problems found, the construction unit was required to rectify them in a timely manner. If necessary, the supervision notice or the project suspension order was issued until the problem was solved.
- Progress control measures: Review the overall progress plan, monthly and weekly progress plan of the construction unit, regularly check the progress implementation, analyze the reasons for the progress deviation, and take adjustment measures (such as increasing personnel, equipment, and optimization of construction sequence, etc.) to ensure that the project is completed on time.
- Cost control measures: Review engineering measurement reports, strictly control engineering changes, and monitor engineering costs to avoid overspending. At the same time, the relationship between the quality, progress, and cost of the project should be coordinated to achieve a balance between the construction goals.
- Safety management measures: Review the construction plan of the construction unit, check the safety protection facilities on the construction site, supervise the safety education and training of the construction personnel, eliminate the potential safety risks in time, and ensure the safety of the construction.
