How do construction workers prepare construction technical information? Any tips? Zhongda Consulting brings the main content of how construction workers prepare construction technical materials for reference.
1. Legal construction procedure documents in the early stage of project construction
(1) Necessary documents for the basic construction procedures of construction projects include project application reports and approvals, land use certificates, construction land approval letters, Environmental impact report, construction project planning permit, public security fire protection design review opinion, construction drawing design document review opinion (civil air defense, energy conservation), civil construction project soil radon concentration test report and other documents.
(2) In accordance with the statutory construction procedure documents for the early stage of project construction in Chapter 1 of the Provincial Statistical Table, collect early stage documents from Party A in a timely manner. Copies of all early stage documents must be stamped with the official seal of Party A and marked. Repository for original documents.
2. Comprehensive management information of construction projects
(1) Unit project construction organization design and construction plan: The project overview and content of the construction organization design must be consistent with the construction drawings and comply with the design and Standards require that you cannot deviate from the actual practice and copy indiscriminately. For example, the energy-saving data of the segment plan should be based on the design requirements. The quality objectives of the plan must be consistent with the highest declared objectives. High-end model plans and expert demonstrations or important special plans must be archived. In addition, subcontracting unit plan review forms must use the provincial unified form.
(2) Drawing joint review record: The first drawing joint review should be before the unit’s project start application report. The detailed drawing number must be filled in at the drawing number. Some major changes such as partial project design changes and drawing joint review , needs to be submitted to the drawing review agency for review; design changes must be stamped with the design registration seal.
(3) Construction site quality management inspection record: This form needs to be stamped with the registration seal of the director. The filling time should be before the start of construction. The quality management system required in the form is printed and attached.
(4) Unit project start application report: Make two copies of the unit project start report, one is the start report including the pile foundation construction period, which is used for evaluation, and the other is the civil engineering (not Including pile foundations), each branch is required to make a branch project start application report.
The construction area in the construction start report should be based on the calculated area in the construction project planning permit; the project manager and chief supervisory engineer should be consistent with the construction permit.
(5) Unit project coordinate positioning measurement record:
1. Draw an orientation map in the blank space in the upper right corner of the plan to indicate the orientation of the proposed building, and indicate it Introduce the position and number of the leveling point and the position of the datum point.
2. The absolute elevation, relative elevation of the introduction level point and the relative elevation of the building (±0.00) should be filled in clearly. Among them: the relative elevation of the building (±0.00) is ±0.00, and the absolute elevation is Design elevation, the relative elevation of the introduction level point = the absolute elevation of the introduction level point - the absolute elevation of the building (±0.00).
3. Positioning basis: Layout and positioning shall be carried out according to the planning fixed-point documents issued by the planning department or the level points provided by the construction unit.
(6) Intermediate project acceptance and handover records
It is divided into the following two situations:
1. When the unit project is jointly constructed by different construction companies , when a construction company has completed the construction tasks of the project it undertook according to the contract, intermediate acceptance handover can be handled between different construction process teams, between different construction units, or between the construction unit and the construction unit.
2. A certain construction enterprise has completed the construction tasks of the project it undertook according to the contract, and the construction unit shall organize the design, supervision and construction general contracting units to participate in the handover and acceptance. Such as support projects, pile foundation projects, door and window projects, steel structures, curtain walls, fine decoration and other projects.
(7) The project summary must include the quantity and quality completion status of unit projects, sub-projects, materials and project testing status, etc.; the quality objectives are consistent with the construction organization design.
3. Project quality control data
(1) Acceptance records
1. Branch project quality control data verification records, branch project safety and functional inspection Data verification and main function spot check records, these two forms are modified based on the unit (subunit) project quality control data verification record and the unit (subunit) project safety and functional inspection data verification and main function spot check record form, each Divisions (sub-divisions) should prepare these two forms accordingly.
2. Branch project quality acceptance record
(1) The project name, construction unit, and subcontracting unit are filled in consistent with other information.
(2) The person in charge of the technical department and the person in charge of the quality department should print the names of the company’s technical person in charge and the person in charge of the quality department, not the project department personnel.
(3) The sub-projects in the division project acceptance record should include all sub-projects in the division: for example, the foundation sub-division should include sub-divisions in the pile foundation sub-division, decoration and decoration projects It should include sub-projects such as doors, windows, railings and handrails.
(4) When summarizing the sub-projects of sub-projects, please note: Whether it is the foundation or the main sub-division, the concrete structure sub-division includes the steel bar sub-item (not the steel bar processing sub-item and the steel bar installation sub-item), Formwork sub-item (not formwork installation sub-item, formwork removal sub-item) (not steel bar processing sub-item, steel bar installation sub-item), formwork sub-item (not formwork installation sub-item, formwork removal sub-item), concrete sub-item, cast-in-place Structure is divided into items; the concept should be clear when summarizing.
(5) For some projects, only the quality acceptance records of the underground structure sub-division projects were made, but the quality acceptance records of the foundation and foundation sub-division projects were not made, or the signatures and seals were incomplete.
3. After acceptance of each branch, the "Branches Project Acceptance Registration Form" issued by the Quality Supervision Station must be collected (this requirement is required in Guangzhou).
(2) Construction technology management records
1. Sub-project quality technical disclosure card
(1) Sub-project technical disclosure card for each sub-project The cards should all correspond to the branch acceptance record one-to-one, and the sub-projects included in the branch acceptance record should have corresponding sub-project technical disclosures;
(2) The recipient cannot only fill in the team group Manager, the final report must be handed over to each worker, and a sign-in slip must be attached to the handover card.
2. Pile foundations, foundations and foundations, and main structure projects (each layer) should be reviewed for the baseline after axis positioning and the project baseline review form should be filled in. The design and reviewed dimensions must be noted.
3. In addition to the signature and seal of the curtain wall design unit, the curtain wall calculation sheet should also be signed and stamped by the original design unit of the project for confirmation.
(3) Construction records
1. The pouring time in the concrete mixing quality record (commercial concrete information) should be consistent with the pouring time in the slump detection record sheet.
2. Waterproof steel plate certificates should be collected and corresponding concealed acceptance records should be kept.
3. Curtain wall sealants must have primer records.
IV. Project safety function inspection data spot check documents
(1) Verticality, elevation, and full height record table
1. Measuring points (axis) Arrangement
⑴Frame structure: Observe each column.
⑵ Wall load-bearing structure: no less than 4 sun corners and no less than 5 columns.
①. At the corner of the building. ②.The intersection of longitudinal wall and transverse wall. ③Both sides of the settlement joints of the building.
2. The number of measurements should be once for each additional floor, no less than 4 times during the entire construction process, and no less than 4 times after the completion of the building and in the first year.
3. Notes
⑴The deviation value should be divided into positive and negative numbers. Those that deviate from the centroid of the building plane are positive, and vice versa.
⑵ The purpose of verticality observation is to control verticality and correct deviations. Therefore, the observation should be synchronized with the construction of the main structure, and attention should be paid to the time of observation.
(2) Building Settlement Observation Record Form
1. General regulations: For high-rise buildings with more than 20 floors and complex high-rise buildings with more than 14 floors, the construction unit It must be completed by entrusting a professional surveying unit.
For high-rise buildings with more than 20 floors and complex high-rise buildings with more than 14 floors, the construction unit must entrust
a professional surveying unit to complete the survey.
2. The project department also needs to observe on its own. For ordinary buildings, observation can be started after the foundation is completed or the basement is completed. For large and high-rise buildings, observation can be started after the foundation cushion or the bottom of the foundation is completed. Settlement observation The frequency and time should be based on the design requirements. Civil buildings should be observed once for every 1 to 5 additional floors. Evaluation projects need to continue to observe 3 to 4 times after completion.
3. The following settlement observation chart should be provided when the project is completed:
⑴ Each observation point and its successive settlement amount (Settlement Observation Results Table) based on the measurement of the leveling point;
⑵ The location map of the observation points drawn based on the floor plan of the building and structure, and the relationship curve between the settlement amount, foundation load and duration drawn from the settlement observation results (it is required that each observation point should be draw a curve graph).
(3) Basement waterproofing effect inspection record
The "basement waterproofing effect inspection record form" should draw an "expanded view of the structural engineering of the inner surface facing the water"
Acceptance conclusion: After inspection, there is a water stain of 80×120mm in the middle of the side wall of A~1 axis 400mm close to the bottom plate, and no leakage is found in the rest.
5. Construction log
The construction log record is too simple. It only records the work status of personnel. It does not contain important production and technical activities during the construction process such as quality inspection and material arrival. , inspection submissions and supervision and random inspections; inspection and guidance by superior authorities; meeting minutes; important division (sub-division), unit (sub-unit) project acceptance status, etc. are not reflected, and construction logs are not recorded, omitted, or supplemented. The phenomenon is relatively common. Moreover, most of the record contents are too simple and cannot fully reflect the location of construction, construction team, quality situation and other construction organization conditions on that day, making the construction log not traceable. It is recommended that the data clerk develop the habit of keeping a log every day, and write down the work status such as material delivery for inspection, concrete test block production, and concealed acceptance in the construction log.
6. As-built drawings
As-built drawings are the basis for the handover and acceptance, production and use, maintenance, reconstruction and expansion of the project. They are one of the important technical files stipulated by the state.
1. All as-built drawings should be stamped with a completion stamp, and the content of the as-built stamp should be improved;
2. Any changes in structural form, process changes, etc. should not be modified on the original construction drawings , Supplementary drawings should be redrawn, and the construction unit is responsible for stamping the completion stamp on the newly drawn drawings. Some simple design changes can also be drawn on the as-built drawings and attached with relevant record instructions. Change the stamp size to 35㎜*15㎜.
7. Sub-item inspection batch quality acceptance documents
(1) Construction engineering division (sub-division), sub-project classification
( 2) In various inspection batch acceptance records, many projects filled in incorrect content, which reduced the authenticity of the data. For example:
1. The wall column formwork installation inspection batch is filled with the "elevation" value;
2. The beam plate formwork installation inspection batch is filled with the "verticality" value;
3. The wall column steel bar installation inspection batch is filled with the "row spacing" and "bent steel bar" values;
4. The concrete appearance quality inspection batch record is filled with the "elevation" value, and the beam and plate Fill in the "Verticality" value.
(3) The signatures and conclusions of each inspection batch form are not filled out in a standardized manner. The main control items are marked with "√" (or "/" if not). The content is not detailed and traceability is lacking. (For example, in the steel bar processing inspection batch, the "mechanical properties inspection" item should fill in the raw material specifications and retest report numbers used in the inspection batch parts; in the formwork removal inspection batch, the "concrete strength when the bottom formwork and its brackets are removed" should be filled in , the strength value of the remaining cured specimen under the same conditions during pressure test, the percentage of reaching the design strength, whether the form removal conditions are met, etc. should be filled in).
