I. Project Structure Diagram
Project structure diagram is an organization tool, which decomposes the structure of a project layer by layer in the form of tree diagram to reflect all the work tasks that make up the project. In the figure, rectangles represent work tasks, and the connections between rectangular boxes are represented by connecting lines.
Some residential building development projects can be decomposed layer by layer according to the construction time, such as Phase I, Phase II and Phase III. However, some industrial construction projects often decompose the project structure layer by layer according to the composition of their production subsystems.
The same construction project can have different project structure decomposition methods, and the project structure decomposition should be combined with the deployment of the whole project implementation and the proposed contract structure.
To sum up, there is no unified model for project structure decomposition, but it should be carried out according to the characteristics of the project and the following principles.
1. Consider the overall deployment of the project progress;
2. Consider the composition of the project;
3. Conducive to the contracting of project implementation tasks (design, construction and material procurement) and the implementation of project implementation tasks, combined with the contract structure;
4. Conducive to the control of project objectives;
5. Combined with the organizational structure of project management, etc.
If necessary, individual projects should also be broken down into project structures.
Second, the coding of the project structure
1. The coding of the project structure is based on the project structure diagram.
2. The coding of project structure is closely related to the coding used in investment control, schedule control, quality control, contract management and information management, but there are differences between them. The project structure chart and the coding of the project structure are the basis for compiling the above other coding.
3. The comprehensive coding of work items consists of 13 characters.
