What's the difference between construction log and supervision log?
Concepts of construction log and supervision log
(a) the construction log
Construction diary, also known as construction diary, is a comprehensive record of construction activities and site changes in the whole construction stage of a construction project. It is also the basic data to deal with construction problems and summarize construction management experience, and it is an important part of project completion acceptance data. The construction log can be established according to the unit, division project or construction work area (team), and the construction unit is responsible for collecting, filling in the records and keeping them.
(2) supervision log
Supervision log is the original record of supervision activities, and it is an important residence for issuing supervision entrustment contracts, compiling supervision completion documents and handling claims, extensions and changes. It is an important original residence for analyzing quality problems; It is the basic component of supervision files. It reflects the actual situation of supervisors participating in project investment, progress, quality, contract management and on-site coordination during the project construction.
Fill in the contents of construction log and supervision log.
(a) the contents of the construction log
1, commencement and completion date, construction survey data, project schedule, instructions and instructions from superiors on project construction and technology, etc.
2, construction scheme, construction technology or method, construction organization and mechanization degree.
3. Quantity and quality of major projects completed on that day.
4. Model/quantity of machinery and equipment used on that day; Variety, specification, quantity and field test results of main materials.
5. Weather, temperature, etc.
6, construction ingredients, mixing, temperature measurement and other results.
7. Problems in construction, such as changing design, conformity between construction and design drawings, changing construction scheme or method, engineering quality accidents, problems found in inspection and their solutions, etc.
8, the owner, supervision, design and superior inspectors put forward improvement opinions, instructions, rectification and closure issues, etc.
Other circumstances that can reflect the construction status of the project.
(2) fill in the contents of the supervision log
Supervision log is an important quality record and an important basis for analyzing and dealing with responsibility problems. The content should be filled in according to the actual situation of everyone's work within the scope of their duties. Quality or safety problems found in engineering construction and backward measures taken shall be recorded in the diary. On-site construction progress, safety and quality, weather, inspection, supervision station, material entry, sampling, concrete quantity and time, acceptance, rectification, etc.
How to write construction log and supervision log well
How to write a good construction log
A complete construction log can guide or infer the future construction. How to write a good construction log? Summarized the following eight contents:
1 date
Record the construction process of the project from start to finish. Specifically, in addition to writing down the Gregorian calendar year, month and day on the construction day, it is also necessary to remember the lunar calendar year, month, day, day of the week and lunar solar terms. Most of the workers on the construction site come from the countryside, and some workers will go home to work during the busy farming season, so we should arrange the project construction. Especially after the completion of the main body of the project, it is necessary to remember it clearly and reflect the actual situation of the construction in the whole process.
2. Weather
It is best to record the weather of a day in three periods: morning, afternoon and evening, and remember the weather conditions such as sunny, cloudy, rainy, snowy, windy, foggy and temperature. This is very important for winter construction, and we can know whether it is necessary to find out the reason for the shutdown one day in the future.
Step 3 attend
The construction management personnel, technicians, all kinds of skilled workers, ordinary workers, random personnel of machinery and equipment, cooks, etc. who were on site that day should be recorded clearly as they were on site. And count the total attendance of the day.
4. Instructions from superiors and minutes of meetings
The instructions of superiors and the contents of various meetings shall be directly recorded in the construction log according to the format of meeting records, and the implementation of instructions of superiors and the contents of meetings on that day shall be recorded.
5. Quality
Record the activities of quality self-inspection, mutual inspection and quality management team. Records should be true, don't deceive yourself, truly reflect the quality level and facilitate improvement. Record the on-site inspection of relevant personnel in the quality supervision department, find out what problems and require improvement methods. The evaluation of personnel by the relevant units shall be truthfully recorded.
6. Safety
Safety work should be listed in a separate record. Every day, the smallest safety problems on the construction site should also be recorded to find out the reasons. Especially in the later stage of construction, managers and workers are prone to be careless, so they should keep records every day and start from small things to prevent industrial accidents.
7. Construction progress
The construction progress of the day shall be recorded by classification. Remember the name of the construction team of the subcontracted project, the parts of the sub-projects they are constructing, the construction progress of each project and the estimated workload of the construction. The coordination of each type of work, what problems still exist between each type of work, and whether the construction progress of the day affects the total construction progress. According to the construction organization design, if there is any impact, we must find out the reasons and take remedial measures, and record what types of work overtime. In addition, the representative parts of mortar and concrete test pieces made on that day shall be recorded, and the pressure delivery date shall be calculated. In addition, the materials supplied by Party A must be planned and listed in advance, provided to relevant personnel, and entered the site in time, and the quantity of materials entered the site on the same day should be recorded. Materials that need to be tested before use must be tested before use, and the test time and representative number shall be recorded. Construction machinery in and out of the time should also be recorded. For some key projects and special processes, the daily workload and instructions of the new cycle should also be recorded.
8, the main problems in the construction
What problems were encountered in the construction that day, how to solve them, what technological innovations were adopted, what new materials and new technologies were adopted, and what the actual construction effect was, were recorded one by one. In case of important problems and drawings changes, records should be made first, and the construction can be started only after the personnel of relevant units sign. For minor issues, truthfully record the actual situation at the scene and sign the minutes that need to be signed. In particular, it should be emphasized that some problems and changes have no major problems on site construction and project quality, and it doesn't matter whether they are signed or not, but they have an impact on project settlement. They should be recorded, and the budget personnel should be notified in time to calculate the engineering quantity, and relevant personnel should be invited to sign.
How to write a good supervision log
The supervision log can dynamically reflect the overall situation of the actual construction of the supervision project and the work effect of the supervision department, leaving traces for the hard work of the supervision engineer. Every supervision engineer should fill in the details. Before filling in the supervision log, relevant information should be collected and all the work contents should be compiled into a book. When filling in, the words should be concise and expressive, and the handwriting should be clear and neat. In my opinion, to write a good supervision log, we should pay attention to the following points: 10:
1, climate It mainly includes the maximum and minimum temperature of a day; Rainfall (snow) that day; Daytime wind; Loss of construction working hours due to climatic reasons. In terms of climate, it is necessary to carry out on-site measurement according to the local weather forecast, such as setting a thermometer on the spot for on-site measurement. Climate conditions not only affect the progress of the project, but also affect the quality of the project (such as the detection and evaluation of conditional maintenance test blocks), so our supervisor must not underestimate the record of climate conditions.
2. progress. It mainly includes the construction content, location and progress of the day, the construction personnel (type of work and quantity), the mechanical equipment (quantity and name) put into use in the construction, and the comparison between the actual construction progress and the planned construction progress of the day. If the construction is postponed or suspended, the reasons should be explained, such as power failure, water cut, bad weather, etc. Under normal circumstances, even if the construction unit has a detailed schedule, it is an armchair strategist, because there are different interference factors in the daily construction process that affect the implementation of the schedule. The supervision engineer should go deep into the construction site to track and check the daily progress plan, check the various resources input and construction organization of the construction unit, and record it in the supervision log in detail.
3. The name, quantity, origin, proposed parts and witness sampling of the raw materials that entered the site that day. The raw materials entering the site shall be registered in the supervision log according to their outer packaging identification and verified by the product certificate, instruction manual and warranty. In terms of quantity, review when necessary; If witness sampling is needed, it shall be timely sampled for inspection, and the sampling quantity, location and sampling personnel shall be clearly recorded. This section should be closed together with the material/equipment/component inspection list.
4. Inspection results of lien, quantity, sampling position and mixture ratio of concrete and mortar test blocks. The maintenance of concrete, concrete and mortar test blocks is related to the safety performance of the structure, so the preparation of test blocks must be witnessed by the supervisor, and this part of the content record must be true and detailed; When sampling concrete blocks, the sampling position, number of groups and sampling person shall be clearly recorded; When recording, it is necessary to emphasize the sampling date and location of the test block in the supervision log, which must be consistent with the field record, parallel inspection and test report.
5, division, disciplines inspection batch acceptance. It is necessary to clearly record the acceptance participants, acceptance time and results. Timely record the problems found in acceptance and inspection, as well as handling opinions and results. Process acceptance is the most abundant part in the supervision log; Sub-projects shall record the personnel in place and acceptance conclusions of the construction, survey, design, construction and supervision parties involved in the inspection; The acceptance of sub-items and inspection lots shall record the participants of the supervision and construction units and the problems found in the acceptance. The problems found, whether oral or written, should be recorded in the log and closed together with the supervision notice (reply form).
6. Record the project inspection sheet, supervision contact sheet and supervision notice issued on the same day.
7. Record the contents of design changes, cost claims and project payment handled on the same day. Design changes can be proposed by any party involved in the project, and must be approved by the designer before being issued by the chief supervision engineer to the constructor for implementation; The supervision log shall record the record of claim handling, the time and reason of claim event, the construction party's claim intention, the time and summary of claim report and the reply of the supervision department.
8. Summary of main topics of supervision regular meeting and special meeting.
9, the construction site safety construction inspection and handling of security risks.
10, oral consultation and instructions, including the consultation opinions between the supervisor and the construction unit. Oral instructions to the construction party, instructions from the project director to the personnel of the supervision department, etc.
Pay attention to the timeliness of the supervision log and record the supervision work completed every day on the same day without delay. Some supervisors turn the logs into weekly and monthly reports, which cannot reflect the actual construction supervision situation, let alone fully reach the designated position. Supervision log records should also be careful not to be vague. For example, some records only record masonry walls, but not masonry parts, construction quality and block preparation. Enriching the contents of the log requires the supervisor to be diligent not only in hands-on, but also in writing, and comprehensively record the contents actually completed that day. When filling in the log, you should also pay attention to the closing problem. The contents of the log are not only closed along with the supervision notice, site records, parallel inspection records and related inspection data, but also closed by itself. Nodes with logs as the core can radiate to all aspects of regulatory data.
conclusion
In the past construction field, materials related to project acceptance and settlement were basically valued by construction units and supervision units, but construction logs and supervision logs were often forgotten. However, from the situation of the construction industry in recent years, construction logs and supervision logs have attracted more and more attention from all parties. Supervision institutions and construction units will conduct spot checks on the construction logs and supervision logs filled in by the construction units. Even in the contracts signed by the construction units and supervision units with the construction units respectively, it is clear that the construction logs and supervision logs should be handed over to the construction units after the project is completed. More importantly, construction logs and supervision logs are sometimes used as the basis for settlement. As long as we pay attention to the filling of the construction log and supervision log, we believe that the construction unit and supervision unit will be able to write a log with engineering value.
