Introduction

In this course project, a work execution project (PDP) is carried out during the construction of a public large-panel building. The building is designed for a polyclinic for 800 visits

By design, the building is a 6-story large-panel building.

The length of the building is 80.5 m, the width is 12 m. The polyclinic building is equipped with elevators.

Construction is carried out in the area of ​ ​ the city of Tver.

The construction area has the following climatic characteristics:

-sung district III.

-wind area I.

-grunt conditions: soil of the base of the construction site - medium sand, not water saturated, design soil resistance - 300 MPa.

Direct project costs will amount to 544,600 rubles. (in 1984 prices).

The implementation of this project for the construction of a clinic will ensure the health of the population. The increase in the number of healthcare facilities after the commissioning of the facility will allow opening additional rooms in which it will be possible to place complex equipment for the diagnosis and treatment of populations. Construction can also provide workplaces for the duration of the project of working construction specialties, specialties related to the construction of industrial industries, such as the production of reinforced concrete products (panels are structural elements of the building), concrete and cement plants, factories for the production of finishing materials (tiles, paint, plaster), and will also allow organizing jobs for service personnel, economists, accountants, management workers.

In addition, the opening of the clinic will provide jobs for medical workers in the city. Reduce social tensions in the city.

Determination of construction duration, scope and labor intensity.

The normative duration of construction in the general case is determined according to SNiP 1.04.03.85 "Standards for the duration of construction and backlog in the construction of enterprises and structures. In this course design, the construction duration is set (2) in the amount of 14 months, 2 of which covers the period of preparatory work.

The scope of work on the construction of the facility is generally determined by the architectural planning solution of the building, the description of the work carried out, given in the design task. In this course design, the scope of work and their scope are specified in (2), but in the future they are specified by calculation:

Costs for unaccounted works are accepted in the amount of 15% of the amount of labor intensity of the main works,

Costs for the improvement of the territory are accepted in the amount of 3% of the cost of construction and construction.

Based on the known data, we develop the Volume, Labor and Demand List for Machine Workers (Table 1).

In order to calculate the scope of works on improvement and total labor intensity of works, it is necessary to calculate the cost of construction and construction works, the amount of overhead expenses of NR and planned accumulations of GON.

All calculations are carried out in 1984 prices.

PP = 544600 rub.

NR = 0.17PZ =0.17544600=92582 rub.

SS = DBE + NP = 544600 + 92582 = 637182 rub.

MON = 0 08SS = 0.08 * 637182 = 50975 rub.

Rub SMR=PZ+NR+PN=544600+92582+50975=688157.

Scope of work on the improvement of the territory:

(0.020.03) * CC = 0.02 * 637.182 = 12.743 thousand rubles

Scope of unaccounted works:

0.15Q=6786*0.15=1017.9 people - dn.

Select a rational way to do the work.

Preparation of the territory is carried out using a bulldozer for a period of at least 2 months (on assignment). Then, mechanized earthworks begin on already prepared areas of the territory.

Mechanized earthworks are carried out by an excavator and a bulldozer. It does not break into captures.

After completion of the MPR, we perform manual soil extraction, in parallel we install the tower crane.

At the time of the start of mechanized earthworks, we are starting unaccounted for work, which we distribute in such a way that there are no so-called "wells" on the schedule of resource requirements.

While the extraction of soil began, the introduction of communications begins.

After soil extraction, we install foundation blocks and basement wall blocks. After its completion, the staircases and basement floor slabs are installed. In parallel, brick partitions are being arranged in the basement.

Waterproofing of the underground part of the base begins after the installation of staircases and basement slabs. Installation work is carried out by a tower crane. The basement is finished after the roofing.

Installation works of the above-ground part include:

installation of internal and external wall panels, stairways, paving slabs, floor slabs, elevator shafts, garbage duct pipes, ventilation units, masonry of load-bearing and enclosing walls in 2va bricks.

The above-ground part of the building is divided into 2nd grabs (1-3 floors and 4 floor attic).

Installation on the second grip begins after completion of installation on the first grip .

After installation on the grip, the construction of brick partitions in ½ bricks, glazing begins. Roofing arrangement is performed after installation of structures is completed. Plumbing works begin after the installation of the coating plates.

When the brick partitions are completed, the filling of the doorways begins. At the end of glazing and roofing, electrical installation is carried out. Upon completion of electrical installation wet plaster of walls, cement bracing and other finishing works are performed. Installation of equipment is performed after installation of floors. After installation of equipment and electrical installation, commissioning begins.

The walls and the ceiling whitewash are painted at the end of the cement bracing production. The construction of tile floors begins at the end of the facing of the walls with ceramic tiles.

Conclusion.

As a result of the application of the in-line method of work, we received:

- could get:

- reduction of the standard construction period (when reducing the construction period, the effect of early commissioning of the facility and reduction of overhead costs in the part that depends on the construction period are taken into account);

- received:

- reduction of the number of workers from 73 to 65.

- use of the minimum number of machines: 29 main construction machines, machines and mechanisms of small mechanization, as well as the maximum number of cars 3 pcs.

Among them are "heavy" mechanization machines 3 pcs.

- performance of works in 1.2 shifts ;

- Almost even consumption of resources;

- no downtime;

- rhythmicity of finished product output;

- favorable conditions for adjoiners, which are uniformly loaded;

-the flow uniformity coefficient is ~ 1.9 (within 1.51.7 the flow uniformity coefficient is considered optimal).

As a result of strict compliance with SNiP instructions, wide use in the construction process of efficient devices for automatic regulation of machines and means of low mechanization, the use of progressive methods of quality control using isotopes, ultrasound, etc., we received high-quality construction products.
