It needs to be constantly analyzed and adjusted according to the actual situation on site and resource demand to ensure the realization of progress objectives; 2.
The structural form is core tube frame shear wall structure.
The handover time of working faces is complete.
Set milestones for positive and negative zeros of all main buildings, capping of main structures, removal of people and goods elevators, completion acceptance, etc., and set the required completion time to achieve early warning; Summary of the effect plan preparation stage of the overall plan preparation: the project contains super high-rise projects, with special attention to construction interpenetration.
Due to the influence of the epidemic situation in the early stage and other external factors, the construction period is extremely tight.
Idea of project plan control: plans at all levels are clear about key routes → milestone early warning data feedback → meeting analysis of reasons for lag → minutes of regular production meeting recording → developing corrective measures to solve problems → minutes of meeting are signed by multiple parties for confirmation → reviewing the master plan → optimizing the annual plan → intercepting monthly and weekly plans → exporting tabular plans → implementing the distribution plan.
The detailed steps are as follows: 1.
The professional subcontracting plan comprehensively analyzes the handover of other disciplines and the mobilization nodes of different types of work; For example, the construction start node of each sub division of large machinery and discipline, the coordination start node of each discipline, etc; Progress management requires rope twisting management.
Project Zoning Layout 3 Project plan preparation ideas in the project plan preparation stage: sort out the WBS decomposition ideas of the plan according to the key and difficult points of project management and the requirements of the contract owner → focus on the overall plan management ideas, Prepare the supporting work into the master control plan → sort out the milestone nodes at all levels of the plan → determine the construction interpenetration model → determine the construction interpenetration nodes → determine the construction ideas → prepare the resource plan → prepare the construction plan → prepare the milestone nodes, set the required completion time to form an early warning; The detailed steps are as follows: 1.
In the process, strengthen the intercommunication of all departments and disciplines.
Intercept the new monthly and weekly progress plans according to the optimized master schedule, export the tables, and implement them on the ground; Summary on project plan management: 1.
According to the analysis results of the key and difficult points of the project construction and the contract requirements, determine the project construction time node, tabular plan, gradually refine the plan according to the time arrangement, and consider the flow of water between the construction of each unit; 2.
The construction site is narrow and difficult to carry out the work.
The progress plan is not a time node, but a dynamic one.
2 Construction period objective The construction period of this project is from July 10, 2019 to December 31, 2022 (1271 days in total), and the main body completion time (main body capping) is 820 days after the commencement.
The first floor of the basement is mainly used for business, and the second floor of the basement is used for parking garage and equipment room area.
Now let’s learn their management experience.
Sort out and analyze each construction node of the project in combination with the contract, the owner’s instructions and the project management requirements, and formulate the key nodes of the project; 3.
Clarify the key work of plans at all levels, and feed back the deviation adjustment plan through multi-level plan implementation; The annual plan, monthly plan and weekly plan of the master plan 2.
Shenzhen Construction Engineering Group Nanshan Science and Technology Innovation Center (Liuxiandong Sixth Neighborhood) General Contracting (Lot I) Project successfully solved the above problems through four level comprehensive plan management.
From the aspects of equipment, materials, labor force, test and detection, inventory the resource needs every month, and adjust and optimize the plan at any time; 4.
The project is divided into 7 plots and several flow divisions; 4.
1 Project overview: The construction area of Nanshan Science and Technology Innovation Center (Liuxiandong Sixth Neighborhood) is about 398000 m2.
Establish a 4-step cycle system of “gradually dismantling the general plan – annual plan – monthly plan – weekly plan implementation”; 3.
Determine the construction sequence and area.
According to the project volume and the characteristics of each construction stage, the labor demand table is formulated, and the peak employment data is identified, and the main construction line plan is prepared; 5.
The basement has two floors.

The plans at all levels shall be filed in order to be reliable; 3.
The documents shall be filed according to the type, and there shall be evidence.
4 Basis of plan control in the project plan control stage: multi-level plan management: four level plan management application, general control plan, interception of annual plan, monthly plan, weekly plan, and coordination with daily implementation; Analyze the progress by drawing the vanguard line every week, and the feedback data of disciplines and days that affect the work lag are clear; The plan management of individual works of each discipline shall be carried out continuously, and the tables shall be exported for auxiliary application to clarify responsibilities and protect the rights and interests of all parties.
In Phase II, there are 7 buildings with 1-43 floors, 3 buildings with 3 units with 1-55 floors, 3 buildings with 1-7 units with 7-10 floors and a basement.
The plan of cross working faces is arranged in an orderly manner, with clear responsibilities.
Have you encountered the following problems with your project? The super high-rise project has a large construction area, and it is difficult to carry out the construction management in an all-round way.
