How to understand and use the relationship between schedule control and schedule control

Duration control is a type of schedule control, which means that schedule control is actually a control that runs through the construction stage. The schedule control includes the control of the early stage of the project (project decision-making, design, bidding and bidding), construction and so on. So two things are not the same concept, hehe.

It is recommended to refer to construction management books.

The knowledge related to this question seems unfamiliar. It is recommended to read some management books.

Work packages are included under the project, and activities are included under the work package. Projects have their own duration, and each work package and activity also has its own duration. We can control the total duration of each job, each work package, and the project.

Schedule control usually refers to a control between the current progress and the target progress.

During the construction and execution of the project, we should try to control the implementation of the project according to the schedule prepared in advance. In the process of control, we must take into account the logical relationship between each work package of the project, the logical management between each activity, and combine the total floating time of the project to complete our project within the time required by the total duration of the project as much as possible.

Therefore, project schedule control is our goal, and duration control is a means for us to achieve schedule control.

In order to achieve our control over the overall progress of the project, we can consider controlling the duration of each work package and each job during the implementation of the project. In addition, in order to control the overall progress of the project, we can also achieve it in some other ways, such as adjusting the logical relationship between each work package, adjusting the working relationship between each job, adjusting the logical relationship between the end and starting FS to start FF or flexible control of FS time between jobs, etc. Or increase the investment of project resources, reduce the total amount of design work, and so on.

In short, schedule control is only a means to achieve schedule control, and there are many other options for schedule control.

If the construction period target control in the central work of the construction stage supervision "four control, two management and one coordination" is different from the construction period target of the bidding documents, the bidding documents of the supervision unit are invalid bids, and the supervision of the enterprise bureau will be 'another way to make a living'!

As the project progresses, the environment and conditions may change, and the construction period control objectives may be adjusted accordingly. However, the construction unit, the contractor, and the supervision unit, their construction period goals are always the same.

Fully familiar with the design drawings of the project, in close contact with the design department, carefully analyze and compare the proposed construction organization design, construction plan and methods, make overall organization and comprehensive arrangement, and formulate phased construction period control points in the construction process to ensure that the project is completed on schedule. The use of sectional flow construction methods, reduce technical intermittent, focus on the main projects, highlight the key points, formulate a strict plan, reasonable construction Tongyouhuai interspersed, as far as possible to compress the construction period, speed up the construction progress.

<> about the role and relationship between schedule control and quality control in construction? If you want to know the answer, the following is the relevant content of the role and relationship between progress control and quality control in the construction of Zhongda Consulting, and the basic situation is as follows:

The objectives of engineering project management are mainly reflected in three aspects: first, functional requirements, that is, to ensure that the quality of engineering projects meets the requirements; the second is the time requirement, that is, to ensure that the project is completed on time; 3. Travel is an investment requirement, that is, to ensure that the investment in the project is under control. As far as the current domestic situation is concerned, it is more practical to take quality control as the theme.

In the process of construction, we must establish and adhere to the most basic project management principle, that is, to ensure the quality of the project under the premise of Peibu, control the progress of the project.

The role and relationship between schedule control and quality control in construction:

1. Progress control is a general term for a series of activities such as planning, implementation, inspection and investigation of the work procedures and duration of the construction stage of the construction stage of the engineering construction project.

2. Quality control is also the most important work in construction projects, and it is the central goal of the three objectives of engineering construction project control.

3. Reasonable construction quality control can overcome the one-sidedness and laissez-faire drawbacks of quality control carried out by the construction unit under the supervision and coordination; Promote the construction unit and the construction unit to jointly do a good job in quality control activities; It is conducive to the continuous improvement of the construction organization design and the quality assurance system of the construction unit.

<> project progress control management should not only be limited to considering the factors of the construction itself, but also should pay enough attention to other relevant links and relevant departments' own factors. For example: construction drawing design, engineering changes, collaborating units, relevant competent units, etc.

Only by comprehensive and effective control of the entire project planning system can the realization of the construction period target be guaranteed.

1. Responsibility to people.

Implement the progress control personnel at all levels, clarify their specific tasks, management positions, and division of responsibilities, mark and implement them in the task division table and management function division table designed by the schedule control organization, and let a special person (or special department) be responsible for the progress control work at the corresponding level.

2. Clarify goals.

Establish a schedule control target system, based on the overall schedule, decompose the project according to the composition, progress and construction stage of the project, clarify the progress control objectives of each participating unit of the project, implement the relevant responsibilities through the contract responsibility letter, and ensure the realization of the overall goal by achieving their respective schedule control objectives separately.

3. Preparation process.

The preparation of the schedule is generally divided into the following steps: establishing the planning framework - defining the activities - determining the duration of the activities - determining the logical relationship between the activities - estimating the resource requirements - formulating and optimizing the schedule - establishing the budget and baseline plan - dynamic tracking and control of the plan.

4. Decompose the progress.

According to the time requirements of the general schedule, the general construction schedule is subdivided into annual, quarterly, monthly, ten-month and other schedules.

5. a control node.

The key lines are the main pure high-level clues, and the start and end milestones of the network plan center are the control nodes. Divide the construction stages, determine the corresponding key progress control objects in different construction stages, and formulate construction rules to ensure the smooth completion of the control nodes.

6. Planning stage: The main work is to formulate the project schedule and review the feasibility of the plan in combination with the project site. Sign a letter of responsibility with the participating units of the project, specify the total duration of the project in the letter of responsibility, and put forward the requirements for the sub-project duration (node duration) for each unit according to the total contract duration.

7. Implementation stage:

1) Supervise the implementation of schedules (weekly, monthly, and quarterly plans) at all levels, check whether there is a delay in the construction period, and assist in removing obstacles that affect the progress of the project.

2) Strengthen communication and coordination with the owner and the supervision unit, so that the technical problems on the site, the change to a larger size is more negotiable, the completion inspection, and the quality problems can be quickly solved.

3) Strengthen the cooperation with the design unit to reduce the stagnation of the construction schedule caused by design changes.

4) Ensure the timely delivery of equipment, materials and funds during the construction process.

5) Regularly and strictly review the construction quality to avoid construction rework caused by substandard construction quality.

8. Summary stage:

Inspect the phased construction results of each unit, commend and reward the units that can complete the construction tasks on time, according to quality and quantity within the required construction period, punish the units that fail to complete the construction on time and summarize the experience, and plan the new construction stage at the same time.

1. If you look at the construction period from a small aspect:

Duration is the completion time of some tasks in a project that can be reasonably split (a reasonable task thickness can be split according to the actual situation of project management).

Duration control is the way to ensure that these planned working hours are managed.

The construction period control only independently controls the completion time of each task (including factors such as people, machines, and materials to ensure the construction period).

2. If the construction period is viewed from a large perspective:

Whether it's the duration of the entire project, or the total completion time of any of them, duration control is actually the same as schedule control.

3. Progress control

It is necessary to ensure the duration of each operation task (of course, including the man-machine factor), as well as the logical relationship between the work tasks, and the constraints and promotion of the man-machine material mixed with the job task relationship.

1.Prepare the overall schedule control plan and detailed schedule.

2.Under the premise of the overall schedule, the contractor is required to make more specific quarterly and monthly work plans and arrangements, which will be balanced by the project company as a whole and coordinated with the design schedule, equipment order plan and other plans.

3.According to the overall schedule of the project, formulate the phased implementation plan of the project, the key node plan of the project, the project equipment procurement plan, etc.

4.Coordinate the designer's construction drawing submission plan, and manage the issuance of construction drawings and modification documents.

5.Preparation of project subcontractors, bidding plans.

6.Prepare special subcontracting and procurement contracts for projects to ensure that various subcontracting and equipment procurement plans meet the requirements of the entire plan schedule.

7.In accordance with the requirements of the total construction period, formulate a phased project schedule, and supervise and inspect the implementation of the project progress of each stage unit.

8.Carry out dynamic management in strict accordance with the planned schedule, and once the schedule is found to be out of schedule, find out the reasons in time, and take corresponding positive measures to adjust it to ensure that the total construction period is completed as scheduled. 9.

Coordinate the construction procedures and schedule relationship between the participating units, and pay special attention to the coordination of the progress relationship between the civil structure and the installation of embedded construction, installation and commissioning construction and fine decoration;
