What is the index control of project construction period?

1.Duration.

2.Described by the number of result states of the project activity.

3.The amount of work done is calculated using the amount of work done and the corresponding contract** (unit price), or budget**. It unifies different types of sub-projects and can better reflect the progress of the project. This is a commonly used progress metric.

4.The most commonly used resource consumption indicators are labor hours, machinery shifts, cost consumption, etc.

The so-called project schedule control refers to the work content, work procedures, duration and cohesion of each stage of the construction of the project, according to the overall goal of the schedule and the principle of optimal allocation of resources, the preparation of the plan and put into practice, and then in the implementation of the schedule in the process of often check whether the actual progress is carried out according to the requirements of the plan, the deviation of the situation is analyzed, and the remedial measures are taken or the original plan is adjusted before being implemented, and so on, until the construction project is completed, accepted and delivered.

The three major control indicators in the construction stage of a construction project are: quality target control; schedule target control; Expense (cost) target control.

A large number of machinery, facilities, materials and people are concentrated in the limited space of the construction site. With the continuous change of the image progress of the project under construction, the cross-operation between machinery and people, and between people will become more and more frequent.

There are many opportunities to be injured, which requires construction workers to strengthen their safety awareness, master the knowledge of laws, regulations, norms and standards in safety production, and put an end to illegal construction and risky operations.

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.

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.
