Defects and countermeasures of construction data management?

The technical data of building engineering construction is a historical record of various forms of information directly formed by construction units in engineering activities, a detailed record of the whole process of engineering construction, an important basis for evaluating the quality level of engineering, and a comprehensive embodiment of the management level of construction enterprises. The formation and management of construction technical data is of great significance to engineering construction. This paper analyzes the importance of building construction materials in engineering construction, the problems existing in the management of building construction materials at present, and the countermeasures.

1 Importance of construction materials in building engineering

1. 1 the objective needs of the development of construction enterprises. With the improvement of standards and technology in the construction industry, the management mode of construction enterprises is gradually in line with international standards. As a part of the management system documents of construction enterprises, building materials must keep up with the development speed of enterprises and realize standardization, standardization, authenticity and information management.

1.2 engineering quality record. Construction materials refer to different forms of historical records, such as words, drawings, charts, audio-visual and so on, which are formed in the process of construction, including basic materials, quality assurance materials, acceptance records of concealed works, quality inspection and evaluation records of partial projects, etc. , is the first-hand information of the whole construction process.

1.3 Follow-up management carrier for project construction. After the project has been put into use for a certain period of time, some quality defects may appear due to construction, environment, owner's use and other reasons. Building materials become the objective basis for maintenance, management, reconstruction and expansion after the project is put into use, and the only on-site basis for project construction. Building construction materials can provide reference data for pipeline layout and concealed works for construction units in other projects, and play a demonstration role.

1.4 Comprehensive reflection of the management level of construction enterprises. Building construction materials are transformed from technical documents and materials formed in the construction process, which are an important part of the project underwriting contract, an important document that objectively reflects and records the main body of the construction unit and the construction process, and one of the direct achievements of the construction unit. It is as important as completing the main body of the project, represents the comprehensive management level of the construction enterprise and is an important basis for evaluating the quality level of the project.

1.5 important materials for connotation construction of construction enterprises. Building materials are the accumulation of technology and experience of construction enterprises, which can be used as reference materials for the exchange of technical experience between employees of construction enterprises, and can also be used as case basis for technical exchange with other construction enterprises, which can guide the construction of other construction projects of construction enterprises and improve the production level and engineering quality of enterprises.

2 problems in the management of construction materials

2. 1 The data arrangement is not standardized, timely, complete and true. The compilation of construction materials is not standardized: it is altered at will, and those who are not altered or altered will not sign; Unclear words, icons and seals; When the information is a copy, the copy is not stamped; Some data conclusions are not clear; As-built drawings do not meet the specification requirements; Inadvertent signature and other construction materials are inconsistent with the actual progress of the project, the compilation of materials is backward, and even the construction materials of "closed practice" appear after the completion of the project. Construction materials are incomplete, some materials are not compiled or omitted, some materials are not returned in time after lending, some materials are not kept properly, and inspection record forms are incomplete. "Building materials built behind closed doors", some building materials can't find any shortcomings, and the data of field measurement, inspection and engineering test are perfect, which is inconsistent with reality. The sampling frequency of the construction unit in the test is insufficient, and the number of sampling representatives is small, so the sampling is not representative. Even some construction units do not test or sample at all, and directly "manufacture" a set of perfect data, which makes the relevant data lack authenticity.

2.2 The implementation of the data management system is not in place, and the responsibility is not up to people. In order to cope with the inspection by the higher authorities, the construction unit did not fundamentally realize the importance of engineering technical data, and often only paid attention to the quality of engineering entities, ignoring the management of construction data, failing to form special regulations on construction data management and reward and punishment system, and lacking supervision mechanism. Or there is a system but no execution, and the rules and regulations are ineffective and become wall decoration. Some construction units do not have full-time librarians. Construction technicians lack the sense of responsibility to file site data in time. Librarians have not formed the habit of collecting information in time, and even some librarians are not in a hurry to do it, but urge them to do it. The supervision engineer did not do a good job of weekly inspection and monthly inspection. Links are out of touch, resulting in less than one person responsible for the management of construction materials.

2.3 data management fir, horizontal non-crossing. Construction engineering data management must pay equal attention to management and technology, and carry out interdisciplinary comprehensive work that intersects with practice. Project engineers, construction technicians, quality inspectors, testers and material engineers are all responsible for the compilation and management of a certain part of the data, and they are all indispensable, but they often lack communication, which leads to the inconsistency of technical data between different types of work in the construction technical data.

2.4 Insufficient data utilization. When there are problems in the process of engineering construction, there is no habit of consulting construction materials in time, but relying on experience and memory to find problems. After the project was put into use, there were quality defects. Instead of going to the urban construction archives to inquire about the engineering technical data in time, we looked for the original construction personnel to understand the situation and infer from memory. It didn't play the role of inquiry and basis for building materials.

2.5 Information management is weak. The information management of small and medium-sized construction enterprises is weak and still stays on the traditional paper management. Data managers rely entirely on engineering experience or copy other engineering data management catalogues in the classification, classification and arrangement of building materials, and rely on manual retrieval for retrieval, which is inefficient and the work results are far from standardized.

3 Analysis of countermeasures for building construction data management

3. 1 Improve the organization and attach importance to data management positions. Establish a construction data management and supervision organization composed of construction units, construction units and supervision units, regularly check the management of construction data, conduct a major investigation after the completion of each branch project and file it in time. Select outstanding personnel who understand business, fine management and have a sense of responsibility as full-time data administrators, who are responsible for the arrangement of construction data of engineering projects in a unified way, and designate special places for data archiving to ensure the safety of construction data preservation.

3.2 Improve data management regulations. Establish a construction data management system, refine all aspects of construction data management, and clarify the job responsibilities of data administrators. The specific contents include: data management process, post setting, compilation specification, basis specification, data content, handover inspection, filing responsibility, filing method, etc.

3.3 Strengthen professional technical training and improve professional quality. Strengthen the training of librarians and related technical personnel, organize regular study, and cultivate a construction technical data management team with theory, technology, management and good business, so that the relevant personnel of data compilation can update their concepts, raise their awareness, change passivity into initiative, seriously understand and implement the national regulations on construction technical data management, and improve the management level of construction data.

3.4 Quantify the daily management of building materials and incorporate them into the year-end assessment. The arrangement and storage of construction materials should pay attention to synchronization: the collection of construction materials should be synchronized with the construction process, and the acceptance of construction materials should be synchronized with the completion acceptance of the project, so as to standardize daily management and ensure double synchronization. The data management of personnel involved in data sorting should be regarded as the year-end assessment.

3.5 Establish an incentive mechanism. The salary structure of librarians breaks away from convention and adopts the system of low basic salary and high reward. With the standardization, timeliness, integrity and authenticity of the data as the weight content, the assessment content is refined and the rewards and punishments are strict. Information compilation and management are added in the assessment of relevant technical personnel, so as to strengthen the communication between various types of work and realize the intersection and coincidence of types of work data.

3.6 Strengthen information management. With the widespread popularization and application of information technology, the information management of building materials has begun. Through the development of construction data management software, the classification, classification, processing and retrieval of construction data are realized by relying on the database, which promotes the standardization and efficiency of construction data management. To sum up, building construction data management is an indispensable part in the process of engineering construction. It is a link in the maintenance and management of the construction process and subsequent projects to record the situation and data of the whole construction process truly and objectively. The quality of construction materials reflects the management level of construction enterprises to some extent. Construction enterprises must fully realize the importance of building materials, apply both soft and hard methods, implement information management, and earnestly implement building materials management.
