Introduction

The work schedule for the object is drawn up in the form of a linear schedule for labor costs and scope of work given in the cost sheet there. The line schedule serves as an official document for the operational control of the progress of work at the site and is designed to determine the sequence and timing of civil, special and installation works carried out during the construction of the facility. These dates are established as a result of rational timing of the duration of certain types of work, accounting for the composition and number of basic resources: working teams and mechanisms. According to the calendar plan, the need for labor and material and technical resources is calculated in time.

On the basis of the calendar plan, they monitor the progress of work and coordinate the work of the performers .

The initial data for the design of the line schedule are: the nomenclature of works, their sequence, shift and the accepted number of workers.

A time-based line schedule is used to plot resource requirements. These schedules allow you to determine the required number of workers, the number of machines, mechanisms, materials and structures in time, and also make it possible to evaluate the correctness of the scheduling in terms of uniformity and continuity of construction and installation work.

Construction master plan - a graphic image of the organization of the construction site for the construction of a specific object, in this case "9 storey residential building."

The construction plan is drawn up with the aim of rational use of the construction site, location of permanent and temporary buildings and structures, warehousing, administrative and household premises and temporary engineering networks serving construction needs.

The main initial data when compiling the construction plan is:

- General plan of the object;

- main technological and construction solutions of the project;

- construction schedule;

- the need for workers;

- information on the need for construction structures;

- a list in the necessary temporary buildings and structures, the need for electricity, water, compressed air.

1.1 General data

The construction site is located in the city of Essentuki, the Coastal microdistrict. The site is free from development, green plantations and engineering communications.

For the relative elevation of 0.000, the level of the clean floor of the first floor is taken, which corresponds to the absolute elevation of 575.00 m.

Seismicity of the district and the development site - 8 points.

Climatic construction area - III B

Snow standard load for II district - 84 kgf/m2

Wind standard load for V district - 60 kgf/m2

Design summer temperature - + 26 C0

Estimated winter temperature - - 18 C0

The humidity zone is normal. The normative depth of ground freezing is 0.8 m.

1.3 Methods of performance of works at the facility

Civil and special works at the facility are performed in accordance with the current regulatory documents defining the rational technology and organization of these works.

The following work procedure is mandatory:

- transferred to the nature of the axis of the building of underground structures, archaeological excavations on the basis of breakdown drawings;

- networks removal to nature is carried out by geodetic organization;

- if the design axes are split from the red lines, the latter must first be transferred to nature and fixed on the ground, after which the axes of the structures must be transferred.

After the axes are removed into nature and fixed on the ground, they are transferred to the performance of zero-cycle work. When performing work on the development of soil of category II, according to the difficulties of development, we accept the excavator E - 3322, equipped with a bucket with teeth.

After pit development and mechanized layout of pit bottom, tape foundation is arranged.

After the installation of the first half of the foundation walls, waterproofing work begins. Upon their completion, the sinuses are backfilled. During the installation of the foundation walls, waterproofing of the foundation, backfilling of the sinuses, work begins related to the installation of the tower crane KB - 403 - B.

Work on the construction of the main structures of the framework begins after the work related to the installation of the monolithic slab of the basement floor. The production of masonry begins after applying the layout axes of the building using geodetic instruments and other measuring devices.

The work is carried out by complex and specialized teams. The bricklayer's workplace is organized in accordance with the basic requirements of the bricklayer's workplace organization. To perform work with maximum capacity, we use hinged-panel scaffolds. Mortar for masonry is brought to the construction site in a ready form and supplied in badges with a capacity of up to 0.2 m2.

The floor installation starts with laying of staircases. Brick after preliminary laying is supplied to the place of work of the bricklayer on standard wooden pallets.

After erection of half the height of the frame, installation of window blocks is started with their subsequent fixation.

The roofing is made by a specialized team.

Roofing works include steam insulation device in the form of one layer of polyethylene film, insulation - plates made of glass staple fiber on synthetic binder, grating, metal scrapers. All materials are raised to the level of coating with a mounting crane. At the end of roofing work, they begin finishing work.

In residential premises, ordinary plaster is made with lime-sand mortar. The floor arrangement is started after the leveling tie is made on the floor surface with a thickness of 20 mm. In plumbing cabins, floors are made of ceramic tiles.

During the works related to interior decoration, external decoration is carried out. The external walls of the building are made with insulation and a protective and decorative layer - plaster on a grid. Simultaneously with the finishing works, the installation crane and crane tracks are dismantled, the surface is planned, and the territory is landscaped.

2. Construction Plot Plan Design

The construction master plan provides for maximum use for the construction of permanent roads, water and electric networks.

The construction plan shows the mechanisms by which the building is built, inventory temporary buildings and structures, permanent and temporary driveways.

Regular and safe traffic through the construction area is ensured by the construction of permanent and temporary roads.

Temporary roads are accepted filled with crushed stone 3 m wide.

Since the construction site is very dense, the site around the building under construction will be filled with solid crushed stone for the passage of mechanisms and construction machines.

At the entrance to the construction site, a barrier is installed, admission to the buildings in operation is provided.

2.1 Construction duration

Duration of construction of the facility is certain according to Construction Norms and Regulations 1.04.0385 * Part II of the section "3", item 1 *, Subparagraphs 6 - make 11.5 months, including 1 month the preparatory period.

According to Clause 15 of the "General Provisions," the duration of construction of facilities to be built:

- in areas with seismicity of 7 points and higher, it is set using a coefficient of 1.1;

The total duration will be:

1.1 x 11.5 = 12.7 months

The final duration of the construction of the facility will be 13 months, including 1 month of the preparatory period.

2.3 Design of temporary buildings and structures

Temporary buildings and structures for construction maintenance should be provided in a minimum amount. The reduction of their volume should be due to the primary construction and use for the construction of permanent buildings and structures (roads, warehouses, garages, repair shops, residential buildings and other facilities of the enterprise under construction), the use of mobile and prefabricated production units, as well as the use of the existing production base for the construction of the economic administrative region.

The group of structures used for construction needs includes: buildings and structures for administrative and economic purposes, household, as well as buildings, structures and installations for production purposes.

The results of the calculation of the construction site demand for temporary buildings and structures are tabulated.

Due to the constrained construction conditions and the impossibility of placing the required number of temporary buildings on the site, it is planned to place domestic premises in an adjacent building.
