Construction information staff year-end summary
Time flies, and has been working in Beijing for more than a year. The data work of this project has also undergone four structural acceptances, two tests of the Beijing Great Wall Cup inspection, and a structural acceptance and completion of the transfer of the project data. Looking back on the past, although the data work has basically reached the expected target, there are urgent needs to reflect on individual deficiencies. To improve, the advanced experience needs to be summarized and continuously improved. Looking forward to the future, the data work is still arduous and long-term, and has a long way to go.
Therefore, at the end of the 09-year-old and structural closure, it is necessary to summarize the work of this project and learn from the lessons learned and lessons learned to better carry out future work.
At the beginning of the project, in order to ensure that the work of the project is carried out in an orderly and standard manner, the project has compiled the “Data Target Design”, “Uniform Data Preparation Standard” and “Construction and Data Management Process”. "Data Target Design" clarifies the objectives of the compilation of the project data and the specific requirements for the collection, collation, compilation scope and preparation of each data; the "Standards for the Preparation of Data" for the fonts, spacing, and cover of the various materials in the project The format of the internal approval form, the format of the submission, etc. are all stipulated uniformly; the "Construction and Data Management Process" clarifies the responsibility of the various aspects of the preparation, collection and collation of the engineering materials during the construction process, and is issued by the project manager. It is a strong guarantee for the smooth and effective operation of engineering materials.
Say easy, do it hard. Although sufficient preparations were made at the beginning of the project, due to the uneven work experience and level of various data related personnel, there were more or less problems in the preparation of the data and the execution of the process. The main issues are as follows:
First, the implementation of individual links in the process is not effective, resulting in a disconnect between the upper and lower links. For example, the concrete demoulding report can not be retrieved from the laboratory in time, which affects the demoulding application, and then delays the inspection of the appearance of the cast-in-place structure.
Second, the compilation of engineering materials is not sufficiently rigorous. For example, the number of individual representatives in the test report is missing; the data of individual inspection items in the inspection lot is too hypocritical to be seen at a glance; the individual data drawings are not detailed and clear.
In response to the above problems, the following four measures are taken during the engineering process:
First, clear the division of responsibilities and supervise the implementation of the process.
Second, timely collection and timely feedback.
Third, regular data rectification, data review again.
Fourth, the catalogue is followed up in a timely manner, perfect data archiving.
Through the above measures, the problem was discovered in time, and the rectification was carried out in the first time, and the inspection was carried out once and for all.
There are detailed requirements for the filling requirements of the various materials, the data regulations and the Great Wall Cup Guide, which are not repeated here. It is only through the exploration and induction of this project, and several aspects that need to be paid attention to in various types of materials are summarized as follows.
First, the construction technical data is strictly controlled.
The construction technical data is the official file for guiding the correct, standardized and scientific construction files, as well as the engineering change situation, and the change, negotiation, and drawing review will be signed by the design and construction unit, and the application and plan will be subject to company-level approval. The team signed. In the event of engineering disputes or other special circumstances, such situations are the most basic and important information for resolving disputes. Therefore, such information must be strictly managed, generally not borrowed, beware of loss, have to borrow, and execute Strict loan registration system.
In addition, the construction of the project while designing, the project changes frequently, design changes, engineering negotiations. Design changes and project negotiation directly affect construction progress and project settlement. If the economic loss is caused by the change or the unsuccessful business communication, the hard work of the entire project department will lose its meaning. Therefore, it is necessary to promptly transfer the changes and negotiations to the relevant personnel of the project department, and the technicians will communicate to the construction team at the forefront of the construction in the first time.
Second, the construction measurement records should be detailed.
The construction measurement record is information to ensure the positioning, size, elevation, position, etc. of the project. "There is nothing wrong with it, and it is not uncommon for the negligence of the line to bring trouble to the subsequent construction." Therefore, the measurement data must be detailed to ensure the accuracy of the measurement construction. For example, if there is a line drawing of the floor plan, a sketch of the hole should be drawn, and the elevation of the line should be indicated. There should be a plan diagram. If the plane is required to be the axis of the plane, the section size of the wall column, the size of the door window, and the axis control line. And the size of the wall column edge line, if it is the outer wall, the door and window opening, draw a section sketch, indicating the elevation of the line.
Third, the construction materials should be complete and effective, and traceable.
There are many kinds of materials in the project, and they come from different manufacturers. The quality of good materials is closed, which lays a solid foundation for the quality of the whole project. All kinds of materials must be provided with quality certification files such as product certification and inspection reports. Because these materials are all from outside units, the traceability of such materials is particularly important. In view of this, the data quality certification files should use the originals as much as possible. When they have to use the copies, they should be clear, complete, effective, and stamped. The official copy of the original unit, indicating the original storage, and the signature and time of the manager, and indicate the time of entry and the location of use.
Fourth, the construction record content should be detailed and specific.
The construction record is formed during the construction process to ensure the quality and safety of the inspection and records. The contents of the record should be detailed and specific. It should not be generalized, and should be consistent with the technical disclosure. For example, the reinforcement of the steel bar, the type, specification, quantity, position, anchoring and joint position, overlap length, protection of the steel bar should be written. Layer thickness, reinforcement of steel bars and blocks, and rust removal of steel bars. When data appears, calculate specific values and avoid using a canonical language. When changes occur, negotiations must also write out the changes and indicate their number.
5. The construction test records shall be timely and complete.
Qualification of the construction test is a prerequisite for the acceptance of the inspection batch project. For example, the steel bar connection test report is the premise of the acceptance inspection of the steel bar installation inspection, and the concrete test report is the premise of the concrete construction inspection batch acceptance. Therefore, the construction test records should be carried out in a step-by-step manner to avoid omissions and affect subsequent construction.
Sixth, the inspection batch acceptance record inspection items should be completed.
The inspection unit is the minimum unit for project acceptance and is the basis for the quality inspection of the sub-project and even the entire construction project. Therefore, the passing of various assessments in the inspection lot directly affects the quality of the sub-project and even the entire construction project. Each inspection item in the inspection lot should not be missed. If there is a pre-embedded item in the inspection package of the pre-embedded part, there is a construction item in the concrete construction inspection lot of the construction joint part.
In the process of data collection and sorting, for the data clerk, the various materials received will be archived separately, and the preparation of the sub-item is a very cumbersome process. The following two measures were taken in this project, which greatly improved work efficiency and ensured the quality of work.
1. Prepare a general catalogue of dynamic data for easy data retrieval.
The general data directory is classified into eight categories of data in the regulations, and is specific to each volume of information in the box. The general data directory is updated continuously with the progress of construction and data, and the equipment is listed in the general catalogue after each volume of information, indicating the problems found in each volume of information. Through the general catalogue, all the information is clear at a glance.
Second, the sub-item is compiled by excel.
Most people use the word to compile the catalog, but compared with excel, its efficiency and function are far behind, and the advantages of excel catalogue are mainly as follows.
1, the operation is simple and fast. First of all, the multi-workbook mode in the same window provides a lot of convenience for unified classification management data. In addition, its cell auto-filling and custom data format functions make it easy to operate quickly. If you enter "November 15th, XX", you only need to enter "9-11-15" after customizing the data to display "November 15th of XX".
2. Assist in statistical summary. With its "screening" function, data filtering can be summarized by conditions. If you want to check the steel wire connection test report to witness whether the batch is enough, as long as you select "testimony" in the screening conditions, excel will list all the witness test reports, and divide the number of witness test reports by the total number of reports, then the steel wire connection test Witness percentage. Or to evaluate the strength of the c40砼 in the project, as long as the “c40” is selected in the screening conditions, all the c40 test reports are listed, including the date of the molding, the construction site, and the strength.
3, intelligent error correction function. In excel, you can limit the range of values in the data in the cell. When the range is out of scope, a prompt dialog box will pop up. For example, in the test report of the steel bar raw material, the test result "roughness ratio σs real / σs standard" should be ≤ 1.3. After setting in excel, when the input value is >1.3, the system will pop up the "fail" prompt, avoiding Enter incorrect or assist in finding non-conforming data.
The data work has been infiltrated from the technical department, the engineering department, the material department and even the business department to all corners of the project department. All departments and personnel have their own responsibilities and mutual constraints, and interlocking, especially the requirements of data exchange, more like A rope binds all the relevant departments and personnel of the project department tightly. This requires all data personnel to be consistent, perfect cooperation, and resolutely prevent the Donovan effect. Lonely palms are hard to beat, strong leadership and system are hardware guarantees, and employees with high quality and excellent business level are software guarantees. Both can combine to create an excellent team that can't compete and fight invincible. First class work.
The rain goes to the snow, and the wind goes by the clouds. In the new days, we will continue to adhere to the fighting spirit of hard work, constant exploration, and advancing difficulties, hold high the great banner of quality engineering, persist in good, abandon bad, and let the information work go one step further.
Therefore, at the end of the 09-year-old and structural closure, it is necessary to summarize the work of this project and learn from the lessons learned and lessons learned to better carry out future work.
