INTRODUCTION

One of the main, integral and important branches of the national economy of the country, ensuring the creation of new ones, as well as the expansion and reconstruction of existing fixed assets, is construction. Capital construction has a crucial role in the development of all industries, increasing the productivity of public labor, raising material well-being and the cultural standard of living of the people.

Construction is carried out on the basis of projects and estimates, which contain all technical solutions and economic justifications, drawings of buildings and structures. The quality of the project, the depth of its development, the scientific validity of technical solutions and the timeliness of design work to a large extent depend on the quality, timing and cost-effectiveness of construction.

Organization of construction production - an interconnected system for preparing for the performance of certain types of work, supplying all types of resources to ensure the efficiency and quality of the performance of certain types of work or the construction of the facility. The organization of construction production should ensure the focus of all organizational, technical and technological solutions on the achievement of the final result - the commissioning of the facility with the necessary quality and on time.

In accordance with [1], the mandatory documentation governing the organization of construction includes:

Construction Organization Project (PIC)

Work Execution Project (WP)

The construction organization project (PIC) is a documentation in which the issues of rational organization of the construction of the entire complex of facilities of this construction site are consolidated.

Work Execution Project (PDP) - documentation in which the issues of rational technology and organization of construction of a specific facility of this construction site are worked out in detail.

The PPM is made directly on the basis of PPP. Construction is prohibited without work projects.

The purpose of the design of the construction organization is to ensure the timely commissioning of production facilities and facilities with the lowest costs and with high quality due to an increase in the organizational and technical level of construction.

The purpose of this course project is to gain skills in developing projects for the construction of civil and industrial buildings, in particular a 9-storey residential building.

In the practice of operational planning and construction production management, the method of network planning and management is widespread.

The total duration of construction and the duration of the preparatory period are assigned in accordance with existing standards. After calculating the network schedule (early and late endings), a critical path is determined and a time-scale schedule is built, and then an era of labor requirements is built on it.

Thus, the main tasks of the course project are: determining the types and volumes of installation and auxiliary work; selection of the most efficient methods of work execution; Calculation of manpower and logistics requirements; Development of the sequence and relationship between individual production processes; determination of building installation dates; identification of the main technical and economic indicators.

1 CALENDAR PLAN

In this course design, the initial data for the development of the network is the architectural and construction drawings, according to which the work execution project is developed.

To develop a network, it is necessary to calculate the quantities of work and determine the methods of work execution, calculate the labor costs, determine the labor intensity and duration of the gripping work.

1.1 Calculation of the scope of work

When calculating the scope of work, it is necessary to comply with the requirements and sequence set out below:

- based on the personal assignment, a list of construction and installation works is drawn up;

- according to GESN, units of quantity of work and time standards by units of measurement are selected;

- the scope of construction and installation works on grips is calculated;

- the total labour intensity of gripping works is calculated by multiplying the volume of gripping works and time standards by units of measurement.

The remaining work quantities are calculated in the labor costing.

6. Drainage device [3], in T.H. certificates of inspection and acceptance of hidden works:

- for drainage elements (drainage layers and their bases, pits, Pipelines and their sprinkling); diaphragms; screens; kernels; underlying layers during installation of instrumentation;

7. Backfilling and compaction of soil [3], including acts of inspection and acceptance of hidden works :

- for preparatory works before backfilling (control of cleaning of sent sinuses from garbage, snow and ice, performance of isolated surfaces of structures, physical and mechanical characteristics of backfilled soil),

- for acceptance of works after execution of works on reverse) backfilling and soil compaction (check of materials and density of backfilled soil);

- backfilling of excavations at points of intersection with roads, sidewalks and other territories with road surfaces;

- for measures required for resumption of works in case of interruptions in performance of works for more than a month, during preservation and depreservation of works.

1.4 List of specialized flows

In this diploma project, the construction of the facility is planned by specialized workflows. At this stage of work the duration of gripping works is calculated. The source data for this is the calculation of labor costs. The number of shifts and the number of people working per shift are assigned. Duration is calculated as the ratio of labor intensity per shift to the product of the number of shifts per number of people working per shift.

CONCLUSION

The continuous improvement of the system of organization and management of construction production is an essential condition for the successful development of the industrial economy of the country as a whole. Successful implementation of continuously increasing volumes of capital investments and construction and installation works is possible only on the basis of the introduction of industrial production methods into construction, complex mechanization of works, effective methods of organizing construction processes.

The whole set of measures to improve planning and the entire economic management mechanism in construction, of course, contributes to the concentration of resources, acceleration of the construction and commissioning of facilities, reduction of the volume of incomplete production and improvement of a number of important technical and economic indicators.

This course project was aimed at gaining skills in developing projects for the construction of civil and industrial buildings, organizing construction production at the construction site. As a result of the work, the types and scope of installation and auxiliary work were determined, the most effective method of work was chosen, the need for labor and material and technical resources was calculated, the sequence of individual production processes and the relationships between them was developed, the construction time of the building and the main technical and economic indicators were determined. The areas of warehouses, temporary buildings and structures that will be required during the production process were calculated .

The development of the course project mainly consisted of the preparation of a calendar plan and a construction plan. The schedule for the construction of the above-ground part of the building was developed in accordance with the in-line method of organizing construction, which significantly reduced the construction time, reduced the number of hours of downtime for workers, machines and mechanisms .

The construction plan was developed in accordance with safety requirements, which would avoid accidents on the territory of the construction site.
