General progress plan and safeguard measures of residential building construction

The main contents of the management and control measures of the construction progress plan include: the preparation of the construction progress plan, the stage control, the main partial progress plan, the method and analysis of the control plan, the control measures of the progress plan, etc.

1 principles of schedule

According to the construction organization design, decompose the milestone plan to ensure the realization of the management objectives promised by our company to the construction unit. Combined with the overall analysis, construction method, resource allocation and the experience of similar projects in our company, our company attaches great importance to this project and determines the overall schedule of this project.

Progress control is an important guarantee for the realization of this project. Through the decomposition of various workloads and quantities, reasonable and scientific construction methods are selected, resources are effectively allocated, subcontractors are effectively coordinated and controlled, and powerful measures are formulated to ensure the implementation of the whole process control of construction progress, ensure the realization of the schedule and achieve the expected goals.

2 overall progress plan

2. 1 The planned commencement date of this project is March, 20**, and the planned completion date is February, 20XX, and the total construction period is 642 days. The specific commencement date shall be subject to the commencement order issued by the chief supervision engineer or the agreement in the contract.

2.2 Determination of General Schedule

According to the main partial project schedule, according to the organization and logical relationship of the project construction, determine the total construction schedule of this project.

3 General schedule control principle

3. 1 On the basis of the total project schedule control, determine the key points and key lines of each division and sub-project as the control focus.

3.2 According to the experience of similar projects that our company has completed, and referring to our company's comprehensive coordination ability and the budgeted number of working days, we will determine the progress plan of each subdivisional work and subdivisional work, and take it as the monitoring point of each subdivisional work and subdivisional work.

3.3 According to the planned budget expenses and the actual completed budget expenses in the project construction, and considering the actual completion of the field work tasks, observe the changes of the project situation and decide whether to speed up and postpone the progress of related subdivisional work. On this basis, the project progress of each subcontract and directly organized subcontract that affects the project progress is estimated, and the difference between the site progress and the total schedule is corrected.

3.4 The monitoring and correction of progress control adopts the front-line method to adjust, and the relationship between each work on the key line and the adjacent work is solved by adjusting the free time difference and the total time difference. The realization of various plans is ultimately guaranteed by various guarantee measures related to the progress.

4. Hierarchical control of progress

4. 1 Primary Master Plan

Express the stage objectives of various professional projects, and derive the total project duration objectives from this, form a master control plan, and provide it to the construction unit, supervision, design and general contractor. The master control plan is managed by crossing diagram and network diagram. In the construction process, with the general schedule as the control baseline and the schedule as the main line, all departments and groups prepare and implement various management plans realized by the comprehensive schedule of the project, and conduct monitoring and dynamic management during the construction process. The master schedule is one of the ways that our company promises to the construction unit to implement the contract schedule guarantee. The overall control plan will be detailed after winning the bid.

4.2 Secondary Schedule Control Plan (Stage Plan)

Based on the general schedule, the main subdivisional work is divided in a targeted way, and the work content that needs to be completed in the specific implementation of each stage is decomposed based on the division of professional stages, so as to form a stage plan, which is convenient for the arrangement, organization and implementation of the progress of each profession, so as to effectively control the progress of the project and provide it to the labor force and subcontractors when they enter the site, so that they can have a clear understanding of their working hours. At the end of each month, inform all personnel, labor subcontractors, material subcontractors and professional subcontractors of the progress of the secondary progress.

4.3 Three-level control plan (monthly progress plan)

On the basis of the secondary progress plan, the work arrangement of flow construction and cross construction will be carried out to further strengthen the scope and intensity of control. Considering the arrangement of the monthly plan, every unit involved in the project construction needs to pay attention to it, specifically control the time required for each working procedure, and fully test the time to be controlled in the specific operations of various professional subcontractors. This is the biggest point of monitoring and implementing management for each subcontractor. The key points that all departments, professional groups and professional subcontractors must abide by are the basis of optimizing dynamic management.

4.4 Auxiliary plan (weekly plan, supplementary plan and itemized control plan)

Supplementary plan: provide the construction unit with the plan for the next month on the 25th of each month, correct the deviation in the plan, make a supplementary plan for the revised plan in time, and report it to the supervisor for approval.

Sub-control plan: according to the project implementation, formulate sub-control plan. In the case of overlapping disciplines, tight construction schedule or complicated working procedures, the sub-item control plan will be adopted. When carrying out the following standard layer construction, the hourly plan of standard layer flowing water construction will be made according to the relationship between flowing water rhythm and working procedure.

Weekly plan: The weekly plan is the concrete implementation of the work plan completed by each professional team and subcontractor every week, which is implemented by the field leaders of each professional at the regular project meeting and checked at the next regular project meeting. The work completed every week and the adjustment and rectification of the work plan for next week will be notified to the construction unit and the supervisor at the regular meeting of the supervisor.
