Description

Bridge construction quality measurement change progress plan management data structure design

Technical Field

The invention designs a bridge construction data structure, which is used for uniformly managing the flows of quality, measurement, change, progress plan and the like in the construction process, thereby realizing the construction informatization and cooperative management and improving the working efficiency.

Background

The bridge construction project management comprises management work such as quality, measurement, change, progress plan and the like, is a set of systematic and standardized business processes, and is required to comply with various standards, specifications, rules and guidance files. Because information circulation and information sharing are not in place, a large amount of repetitive human labor exists in the current engineering management, errors and consumption are increased, and the overall target is influenced. The main reasons for this are the following:

1. the standard is more standard, the formats are not uniform, and when the engineering personnel finish the construction task, charts, files and archival data are required to be formed respectively according to various standard requirements;

2. existing tool software only aims at the specific requirement of a certain specification and does not consider data universality and data sharing;

3. the project data storage and query functions are backward, information circulation and sharing among links are difficult, and information loss generally exists;

4. when the engineering project is specifically implemented, each responsible party only concerns the tasks of the principal and the subordinate, and overall planning and viewing are lacked;

in order to solve the above problems, the building department points out that a Building Information Model (BIM) is strongly promoted as an important work in an informatization development schema, and strengthens the use of a building information management system.

The core of the BIM idea is information management and collaborative management. Through digital modeling software, model information is taken as a core, business of each process such as cost management, risk management, construction process management, quality management and the like is informationized, and each process is cooperatively managed through informationized data, so that the overall management efficiency is improved. However, in actual projects, the use condition of BIM is not satisfactory, and the following reasons mainly exist:

1. although BIM system is introduced into enterprises, the operation is required by professional personnel, and the BIM system is difficult to be applied to the whole construction process due to the limitation of time, manpower and the like;

2. although new technologies are rapidly applied by design and construction units, owners, supervision units, supervision and government departments lack initiative learning and knowledge updating power, and the popularization of the BIM technology is inhibited;

3. the BIM theoretical research in the field of bridge engineering is not supported sufficiently, and a set of feasible bridge information model framework is not formed;

4. the BIM data standard is designed without considering the connection with the existing standard, so that the BIM model cannot be directly used for construction quality, measurement, change and schedule management.

Disclosure of Invention

The cooperative management needs system work and information sharing, and a uniform data format is the basis of information cooperation. To facilitate the sharing, the data should satisfy the following requirements:

1. reflecting the whole construction process, and meeting the requirements of quality, measurement, change, schedule management and the like;

2. the data structure is standardized and easy to popularize; informationization and easy sharing;

3. large-scale software and professionals are not needed;

4. and various technical standards are compatible, and the requirements of supervision and acceptance are met.

The invention takes BIM coding thought as guidance, designs a set of data structure model considering all management procedures around quality, measurement, change and progress planning data in bridge construction, and carries out cooperative management on the whole process of a project on the basis. The data structure is composed of a quality information table, a measurement detail table, a change summary table and a change expense table 4 tables, and the member number is used as a bridge for connecting data in different tables. And inputting the basic data in the table before construction, and inputting the process data in the construction. The data structure does not need large-scale software and professionals, is suitable for engineers to use, is clear in data structure hierarchy, and is easy to expand and access to a BIM system.

The component numbers are as follows: according to the 6-level coding principle of BIM, on the basis of quality unit division, a first-level subsection project and a first-level subsection project are respectively added, 6-level division of a single contract section is realized according to the sequence of an upper structure, a lower structure, a bridge deck attachment and a last foundation, the structure is decomposed into basic components, and the basic components are corresponding to construction procedures and are all numbered independently.

Quality information table: and (4) mapping the component number with a planning date, a completion date, an acceptance date, a construction quality accountant, a supervision quality accountant, a structure parameter and a material parameter, and establishing a quality information table to realize quality management.

Measurement detail table: and (4) mapping the component number and the list subdirectory, and establishing a metering detailed table to realize metering management.

Change summary sheet

Changing the number: the unique identifier of the item change, 1 number corresponds to 1 change;

the person responsible: the changed process is responsible for preventing the data loss in the circulation process;

the type of change: a change notice initiated by a proctoring engineer or a change declaration initiated by a contractor;

the cost is as follows: the cost caused by the change is increased or reduced, the cost needs to be estimated when a change notice or a change application is initiated, and the actual cost is determined after the change is completed;

the process comprises the following steps: the contractor, the supervision, the design, the owner and other departments needing to sign changes can know the stay condition of the changes at each node by a clear flow and supervise and prompt the signing as soon as possible.

Changing the expense table: the change number and the component number establish a mapping and calculate a corresponding inventory cost adjustment.

Managing a progress plan: establishing mapping between the component number and the planning date of the component to realize schedule management;

counting the completed components to obtain progress data;

the acceptance date is compared with the planning date, so that the actual execution condition of the plan can be mastered;

and summarizing the list details corresponding to the finished components to obtain the yield value.

Component-mass mapping table: determining the mapping rule of the component number and the quality unit division number, and facilitating quality data arrangement:

the component unit numbering rule is as follows: project name-unit project-subsection 1-subsection 2;

the quality unit numbering rule is as follows: project name-unit project-subsection project-project sub-project;

when the quality number is generated from the component number, the project name and the unit project are kept unchanged, and then the subsection 2 and the subsection 1 of the component unit are taken as the subsection project and the subsection project name of the quality unit in sequence, and the subsection project are numbered again.

And (3) data generation: data are divided into two categories, namely basic data which are generated before construction and are kept unchanged in the process, and process data which are generated in the construction process.

The basic data consists of component numbers, quality information and measurement details:

1. after the component numbers are obtained through structural decomposition, a quality information table is established, a construction drawing is consulted, and corresponding data are filled in a construction quality responsible person, a supervision quality responsible person, structural information and material information;

2. according to the construction organization plan, filling the plan completion date of each component in the 'plan date' column in the quality information table;

3. and looking up the construction drawing, establishing component number and engineering quantity list mapping, calculating and filling the list engineering quantity of each component, and finishing the metering list. The table is relatively fixed during construction, and unless a change occurs that involves the adjustment of the component list, data other than "measured period" does not change.

The process data is quality, measurement, change and progress data which are continuously generated in the construction process:

1. after the process of the component is finished and the acceptance is qualified, the columns of 'finishing date' and 'acceptance date' corresponding to the component in the quality information table are filled with data, and meanwhile, the 'measuring period number' information in the measuring detail table is automatically generated according to the 'acceptance date' of the quality information table;

2. when the change is generated, the change summary table and the change expense table are filled, and the corresponding items in the metering detail table are automatically adjusted;

3. the progress report is generated from the quality information table.
