1. Be familiar with the construction drawings, raise questions and solve them

Preparation before the start of the project is the most important. First, be familiar with the design construction drawings and design instructions. When engaged in different jobs, look at them from different angles and grasp the key points.

2. Fill in and prepare the necessary information for the start of the project

Fill in the Municipal Project Construction Safety Start Conditions Evaluation Form, Municipal Project Civilized Construction Start Conditions Evaluation Form, and Project Quality Assurance System Review Form (attached is the seven-member responsibility system) ), start-up report, witness sampling schedule, construction organization design, and safety construction organization design. Once the materials are complete, go to the relevant unit to complete the signature, seal, and review procedures.

3. Classify and store various data

In order to facilitate the organization of future completion data, during the daily data collection process, the order of the municipal road (drainage) project completion file checklist in the archives is classified and archived; for construction and Although the correspondence data of owners, supervisors and other relevant units are not archived, they should be classified and organized; various forms used in construction should be numbered and placed by the unit for easy access during use. Project data are divided into four parts: construction technology management materials, project quality assurance materials, project quality inspection and assessment materials, and as-built drawings. Road and drainage project data are organized separately. Generally, construction technical management materials for roads and drainage projects are put into the drainage project data. However, technical change notices, technical work contact sheets, construction records, concrete pouring records, technical explanation records, etc. are included in road, drainage and drainage project data. Drainage areas are divided into road and drainage data respectively.

2. What should be done after the project starts

1. Raw material submission for inspection

When starting construction, raw materials must be sent to the testing center commissioned by the Municipal Quality Supervision Station for inspection, and representative soil samples from the site must be taken and sent to the head office laboratory for compaction testing. When submitting for inspection, attention should be paid to strict quality control, and only materials that pass the inspection are allowed to be used.

2. Collection work that can be carried out at the same time

Archive the project budget, survey and stake review records, drawing joint review records, and technical disclosure records together with the commencement report, construction organization design, and construction license.

3. Precautions for collecting and filling in information during the construction process

1. Collect material quality certification documents

As various materials are continuously purchased during the construction process, it is necessary to collect the factory certificate and valid test report (with CMA mark) of each material, which must be original. The time, quantity and variety specifications of valid certificates must be consistent with the time when the materials enter the site. In particular, cement must have a 28-day strength factory inspection sheet; the identification and specifications of steel must be consistent with the factory certificate.

2. Fill in the information

To fill in the quality inspection information, you need to fill in the supervision specification form. The writing requirements are standardized and cannot be altered. Use durable writing materials, such as carbon ink, or the commonly used gel pen. Supervision forms are generally made in triplicate, and hidden records and process forms are made in duplicate. Fill out the form in accordance with the corresponding process acceptance content of the specifications and standards. Different supervisors have different requirements for information. You should actively communicate with the supervisor before filling in the inspection information and fill it out after reaching an agreement. Concealed records and process tables should indicate the specific location, process name, station number, east and west sides (half width), south and north sides (half width) or left and right sides (half width), so that it will be clearer and clearer when sorting out the data in the future. Intuitive; its content should be realistic and cannot be copied. For example, the trench excavation process should not be written as "free of frozen soil" in winter; the flat foundation pipe seat process is grouped together in the specification, but it is two different processes, and the stick concrete pouring time is different, so it must be filled in separately; the ditch filling report When the trench excavation is concealed, a cross-sectional view of the trench excavation should be attached, and the dimensions should be marked. When the soil quality of the excavation is more complex, the soil quality should be roughly marked. After the base process of each part of the road has been submitted for inspection, there is no need to fill in the unconcealed process. Concealed records, such as surface layers, stations, lying stones, sidewalk bricks (surface layer), prefabricated block slope protection, etc. for express lanes and non-motorized lanes; when filling in the process table, attention should be paid to the selection of inspection items, because not all of them are included in the specifications. Processes, when encountering different processes, generally choose the ones that are closer, such as road bed, base layer, surface layer, etc. in the specification, but there is no distinction between express lanes and non-motorized lanes. When non-motorized lanes need to be inspected, they should be followed by express lanes. The road bed is the same item, but the inspection items are different. The non-motorized lane has a center line elevation. When filling in the deviation value in the process table, you should also pay attention to some details. For example, the deviation value of the flatness item in the road bed is 20mm. If you do not go to the construction site for on-site inspection, it is easy to make mistakes in filling in negative values. It is generally believed that as long as a negative value is an unqualified deviation value, the reading measured with a feeler gauge can only be a positive value, that is, a reading exceeding 20mm. is the unqualified deviation value; the pass rate with the △ symbol in the test items must reach 100%.

3. Collect test reports

Test reports are an important part of project data and are project quality assurance materials. 70% of test reports are self-inspection reports and 30% are witness sampling reports, commissioned by the Municipal Quality Supervision Station. According to the testing center, this 30% is mandatory. There are corresponding tests before and after entering each process of construction. You need to be familiar with various tests. The test report after the test is completed should be collected completely, with the station number, time, and information in the data. Concrete pouring records, construction records, etc. are consistent. Most of the data in the project are related to each other. Not only are they consistent, the summary and assessment records also need to be filled in based on the test report.

4. When the project is coming to an end, the completion data compilation work can be carried out in advance

1. Summarize the data

Check whether there are omissions, writing errors, etc. in the inspection data; summarize and calculate the points of all process evaluation forms to fill in the process quality evaluation summary form, part quality evaluation form, and unit project quality evaluation Table, the pass rate of all processes, parts and unit projects are reflected in these three tables. Upon completion, the signature and seal procedures of the supervisor and the owner are required. Organize and summarize all construction technology, quality assurance, assessment data and as-built drawings in the order of the unified file list of the Urban Construction Archives.

2. Copying and binding

Copy the required number of sets (one set each for the owner and the receiving unit; supervision and design only see the archive) and bind them into a volume. The set sent to the filing office must be bound with kraft paper, and the set sent to the archives must be unbound originals. The archives has special requirements for completion, and a catalog of as-built drawings must be prepared and stamped by the supervisor.

3. Requirements for the preparation of as-built drawings

The as-built drawings should draw all changes and truthfully reflect the current status after completion. If there are large facilities in the road section, they must also be marked. After completion, a completion stamp and signature procedures must be stamped. complete.

5. Data collection after project completion

Fill in the project completion report, project delivery acceptance certificate and quality warranty letter. It must be the original document, with complete signature and seal procedures. After the completion acceptance meeting, put the completion meeting minutes into the completion documents, which is basically a complete set of project completion documents.

With the rapid development of municipal infrastructure construction, municipal engineering data are required to be more comprehensive and complete. Only by constantly learning and mastering new organizing methods can we do this job well.
