1. Each participant representing different interests has different goals and time ranges for progress control, and each has its own plan.

2. Progress control is a process of dynamic management

3. The purpose of progress control is to achieve progress goals through control

4. We must establish and adhere to the most basic project management principles to control the progress of the project while ensuring quality.

1. Owner: Control the progress of the entire project implementation phase. Control design preparation, design, construction, procurement, and work plans before use

2. Designer: Control the progress of the design work according to the requirements of the design task entrustment contract for the progress of the design work. Internationally, the design progress is mainly the drawing plan of each stage, and the design progress is coordinated with the progress of bidding, construction, material procurement, etc.

3. Construction party: Control the construction progress according to the construction progress requirements of the construction task entrustment contract

4. Supplier: Control the supply progress according to the supply requirements of the supply contract

Classification

The significance of computer-aided engineering network planning

1. Overall progress target: refers to the progress target of the entire project, which is determined during the project definition during the decision-making phase of the project.

2. The control of the overall progress target is the task of the owner's project management. When using general project contracting, the general contractor assists the owner in controlling the overall progress target.

3. Before controlling the overall progress target, the possibility of achieving the target should first be analyzed and demonstrated.

4. During the project implementation phase, the overall project progress includes

1. The overall progress target demonstration is not simply the preparation of the overall progress plan. It involves many issues in the condition analysis and project implementation planning of the project implementation (overall progress planning, condition analysis, implementation planning)

2. The core work of demonstrating the overall progress target of large-scale construction projects is to demonstrate the possibility of achieving the overall progress target by preparing a general progress outline.

3. Main contents of the overall progress outline

1. Research and collect information

2. Project structure analysis

3. Structural Analysis of Schedule Planning System

4. Project work code

5. Prepare progress plans for each level

6. Coordinate the relationship between progress plans at all levels and prepare the overall progress plan

7. If the prepared overall progress plan does not meet the project progress target. try to adjust

8. If the progress target cannot be achieved after multiple adjustments, the project will be reported to the chief decision-maker.

1. Understand and collect information and information related to the determination of project schedule goals during the project decision-making stage

2. Collect organizational, management, economic and technical information related to the project's progress

3. Collect progress data on similar projects

4. Understand and investigate the overall deployment of the project

5. Understand and investigate the subjective and objective conditions for the implementation of the project

6. The structural analysis of large-scale construction projects is based on the need to prepare the overall progress outline, decompose the entire project layer by layer, and establish the corresponding work directory

1. The simplest and most widely used

2. A brief description of the job can be placed on the bar chart

3. Work can be sorted by time, responsibility, project objects and similar resources

4. Suitable for small projects or sub-projects of large projects, it can be used to calculate resource requirements and outline progress.

5. Advantages of bar chart

6. Disadvantages of Bar Charts

1. Basic concepts of dual-code network planning

2. Double code network diagram drawing rules

3. Calculation of planning time parameters for dual-code network

Characteristics of the dual-code time scale network plan diagram

Calculation of parameters of double-code time scale network plan

Dual code time scale network calculation principle

Node: Each node in a single-code network represents a piece of work; the tail node number of the arrow line should be smaller than the arrow node number. A job must have a unique node and a corresponding number

arrow line

Line: Node numbers are expressed in order from small to large.

Drawing rules for single-code network diagrams

Key work: The work with the smallest total time difference is the key work

Determination of critical lines: lines from the starting node to the end node are critical tasks, and the time interval of all tasks is zero

1. When the calculated duration does not meet the planned duration

2. Contents of schedule adjustment

3. How to adjust network plans

1. Attention should be paid to a sound organizational system, and there should be dedicated personnel in progress control positions, preparation and adjustment of progress plans, organizational theory, and strengthening of progress plan approval procedures and meetings.

2. Carry out organizational design related to progress control meetings to clarify; meeting type, host, personnel from participating units, convening time, organization, distribution and confirmation of meeting documents (no meeting location, process)

1. Design technology: different design concepts, design technology routes, and design plans

2. Construction Technology: Changes in construction technology, construction methods and construction machinery
