(1) Project Overview and Characteristics Analysis
Analyze and summarize the nature, scale, construction site, construction method, building structure characteristics, delivery period by stages, requirements of the construction unit and available conditions of this project.
(2) Selection of construction scheme
According to the analysis of the general situation and characteristics of the project, combined with the available resources, fully deploy the construction tasks and determine the overall construction sequence and flow direction; Choose the construction methods and construction machinery for the main types of work; Determine the construction sequence of each subdivisional work and choose the best scheme.
(3) Prepare the construction progress plan
Advanced planning theory and methods should be adopted in the preparation of construction schedule plan, and the construction sequence and operation time of each process should be reasonably determined, so as to achieve the best combination of construction period, cost and resource utilization, that is, balanced resources, reasonable construction period and low cost.
(4) Construction preparation work plan
Determine the content of construction preparation, start and end time, workload, the number of people who have completed all the work and the specific person in charge.
(5) Demand planning of labor, construction machinery, transportation equipment, main building materials, components and semi-finished products to solve the supply problem.
(6) Construction scheme design
Its purpose is to solve the plane and space layout problem of the construction site.
(7) Main technical and economic indicators
Evaluate the overall technical and economic benefits of the compiled construction organization design, such as the use of time limit for a project, quality, cost, safety and other indicators.

Functions of construction organization
Construction organization design is an important means of scientific management of construction activities. Its function is to define the construction scheme, construction sequence, labor organization measures, construction progress plan and resource supply and demand plan of this project, to define the specific location of temporary facilities, materials and machines, to effectively use the construction site and improve economic benefits.
Construction organization design also has the function of overall arrangement and coordination of various relations in construction.
Experience has proved that if the construction organization design of a project can reflect the objective reality, conform to the requirements of national policies and contracts, conform to the laws of construction technology, and be seriously implemented, then the construction can be carried out in an orderly manner and the investment benefit can be better brought into play.
Construction organization type
Construction organization design can be divided into three categories according to different design stages and compilation objects: overall design of construction organization, construction organization design of unit project and construction scheme.
(1) Overall design of construction organization
The general design of construction organization is a construction organization design based on group project or super-large project composed of several units. The general design of the construction organization is generally carried out by the general contractor under the leadership of the chief engineer after the preliminary design or expanded preliminary design of the construction project is approved. The construction unit, design unit and subcontractors shall assist the general contractor.
The overall design of construction organization plays an overall planning and key control role in the whole construction process of the project. Its task is to determine the development program of the construction project, the construction scheme of the main building, the overall construction progress and resource demand plan of the construction project, and the overall planning of the construction site.
(2) the unit project construction organization design
The unit project construction organization design is a T-shaped construction organization design based on the unit (sub-unit) project, which plays a guiding and restraining role in the T-shaped construction process of the unit (sub-unit) project. 1 The construction organization design of the unit project is compiled under the leadership of the person in charge of the construction project after the completion of the construction drawing design and before the project starts.
(3) Construction scheme
The construction scheme is the construction technology and organization scheme based on the division (sub-division) project or special project to guide the construction process. The technical person in charge of the project is responsible for the preparation of the construction plan.
For key and difficult sub-division (sub-division) projects and high-risk sub-division (sub-division) projects, special construction plans should be prepared before construction; For divisional (sub-divisional) projects with greater risks than a certain scale, experts shall be organized to demonstrate the special scheme.
