Introduction
The plans for the development of the national economy provide for a more effective use of capital investments in the field of construction, a reduction in the labor intensity and cost of construction due to improved planning and organization of construction. Much attention is paid to increasing labor productivity, as well as the quality and reliability of the erected facilities.
Recently, great work has been carried out to unify the architectural solutions of buildings of various purposes and improve their structures. Efficient reinforced concrete structures are widely introduced into production. Construction has been translated into better planning and economic stimulus principles, which made it possible to incorporate many reserves, streamline the design and estimate business, and improve the quality of facilities being built.
The main attention is paid to increasing the efficiency of capital investments, improving their reproductive and technological structure. The concentration of material, financial and labor costs should be aimed at the technical re-equipment and reconstruction of existing enterprises and structures that determine scientific and technological progress.
It is especially important to continue the industrialization of construction production, to turn it into a single industrial construction process for the construction of objects from factory-made elements. Switch to a comprehensive supply of engineering and technical equipment to construction sites, enlarged units. Accelerate the creation and implementation of advanced technology, machine systems and mechanisms that ensure the integrated mechanization of construction and installation work, especially in the conditions of reconstruction of existing enterprises. Replace traditional labor-intensive processes with modern industrial methods in individual works.
Reduce manual work. Implement more advanced forms and methods of work, develop a brigade contract, enlarge brigades, improve the organization of their work. To increase the mobility of construction organizations for the construction of facilities in uninhabited and remote areas in a shorter time frame.

The work is carried out in the spring-summer period and is carried out in 2 shifts.
The start of the work is April month.
The duration of execution is 4 days.
1.2. Technology and organization of works
1.2.1. Selection of installation crane.
Initial data for selection are dimensions and volumetric planning solutions of the building, parameters and working positions of the loads, method and technical position of installation, conditions of work.
In low-rise construction, the use of a boom crane is advisable.
The installation crane is selected according to the following technical characteristics:
- crane boom length;
- crane boom outburst;
- required hook lifting height;
- value of crane load moment at maximum departure;
- value of crane load moment at maximum weight;
- value of required lifting capacity.
Crane parameters shall meet the following requirements:
- the crane shall set the farthest structure to its design position;
- the crane at the same boom length shall set the farthest structure to its design position regardless of its weight.
For boom self-propelled cranes on caterpillar or pneumatic wheel travel height of boom (hook) S, boom length Lc and boom (hook) L are determined.
For a crane without a goose, the lifting height of the boom (hook), m.
d - distance between the projecting part of the building and the tail part of the crane during its turning, is accepted - 1 m;
Rzg - radius described by the tail of the crane, m.
Drawing of 1:200 scale crane position diagram (Fig. 1).
- determine the position of point E (1 m) from the outline of the building;
- axis/M M/, 1.5 m from crane parking level;
-- through point E, at an angle of 60 °, we draw a straight line (A K);
- we find the position of the crane rotation axis (1.5 m away from the building);
- measure line lengths, recalculate in scale, [AP] = 34 m, [PT] = 23.5 m, [AK] = 39.5 m.
This corresponds to the height of the boom rise Nc = 34 m., boom departure L = 23.5 m., Boom length Lc = 39.56 m.
Based on graphically found parameters of cranes, according to tables and schedules of lifting capacity, take-off and hook lifting height, select the following cranes:
-- FAUN – RTF – 50;
- COP - 8362;
- JAG - 50;
The technical and economic parameters of the selected cranes are entered in Table 1.
It is most profitable to use the KS pneumatic valve - 8362A (Fig. 2).
1.2.2. Instructions for the production of stone works.
Justifications for the work organization scheme.
When conducting the construction of external and internal load-bearing walls, inter-apartment and inter-room brick partitions, the requirements of SNiP 12012004 "Construction Organization" must be complied with. Organization of construction production, SNiP 3.03.0187. Bearing and enclosing structures, SNiP 12042002 (section 9), as well as SNiP 12032001. Labor safety in construction. Part 1.

- date of manufacture of delivered construction materials,
- on strength characteristics of materials;
- on symbols in accordance with GOST or TU.
Requirements for applied construction materials.
The brick used for masonry shall comply with GOST for these building materials. The quality of the brick delivered to the floor during masonry is checked by the performers (masons) by visual inspection (Fig. 4).
Prefabricated reinforced concrete straps of window and door openings shall not have chips, cracks, protrusions of metal reinforcement on the surface. The side surface of the bridges shall be marked with indelible paint.
Metal reinforcement, reinforcing masonry nets and rods shall be without visible signs of corrosion (Fig. 5).
The mortar used for masonry shall have a mobility of at least 7 cm. In winter working conditions lime additives and plasticizing - air-entrapping chemical additive of soaked liquor (PMC) shall be added to the masonry solution in an amount not exceeding 0.8 g per 1 kg of cement (Fig. 6). In winter conditions of stone works, the temperature of the mortar at the time of its shipment should not be lower than + 25 ° С, and at the time of laying in the wall - + 10 ° С. At ambient air temperature below 15 ° С, one grade above design grade solution shall be used.
It is forbidden to use bricks, prefabricated bars and mortar, for which the supplier does not submit quality documents.
Brick delivery to the facility is carried out in packages in specially equipped on-board machines. Packages with brick (Fig.9) are stored on a planned site on pallets or reinforced concrete slab (Fig.8) in the crane area in rows with a gap between pallets of 100-120mm. A passage with a width of 0.7 sound1.0m should be left after 3-4 rows of pallets. It is allowed to store packages with brick stacks on gaskets, the height of the stack is not more than 2 tiers. Brick is fed to working place in traverse case.
Prefabricated reinforced concrete bridges are stored in stacks on wooden inventory linings and gaskets with a thickness of at least 50 mm. Placement of liners and gaskets must be not more than 200 mm from the ends of stored items. The height of the stack shall not exceed three rows of height.
Delivery of masonry mortar to the construction site (Fig. 10) is carried out by car dump trucks. In order to prevent its delamination, the solution is supplied to the masons workplace by crane only after it is reloaded into boxes through a screw unit for receiving, mixing and dispensing masonry solution with a forced driver (Fig. 11). The mortar and concrete mixture are supplied to the workplace by a mounting crane in boxes with a capacity of 0.35 m3, with filling up to 0.25 m3.
Instructions on work execution technology.
Masonry of external and internal load-bearing walls, as well as partitions, shall be performed in accordance with the rules for the production and acceptance of works (SNII1778), compliance with which ensures the required strength of the structures to be erected and high quality of work, working drawings for the constructed structure, the work design and this Job Instruction.
The mason's workplace during wall masonry includes a section of the erected wall and a part of the area adjacent to it, within which materials, devices, a tool are placed and the mason itself moves. The mason's workplace consists of three zones: working 1 - a free strip along the masonry on which the masons work; material zones 2 - strips on which brick, mortar and parts are placed, laid in masonry as it is erected; 3 - in this area there are riggers providing bricklayers with materials and embedded parts. The total width of the workplace is 2.5... 2.6 m (Fig. 3).
When laying brick walls, the material is placed along the front of the work in an alternating order: brick on pallets, mortar in a drawer, then brick on pallets again. In order to be convenient to supply the solution to the walls, the distance between adjacent boxes with the solution should not exceed Z... 3.5 m, and they should be placed on a long side perpendicular to the wall. It is not necessary to place boxes outside the material zone and further than 2 m from the place of solution placement in the structure, since this increases the physical load on the worker and increases the loss of solution.
The stock of brick or stone at the workplace should correspond to the 2... 4-hour need for them. The solution is loaded into the boxes just before the start of operation. Jobs should not be cluttered with excess materials and scaffolding and forests should be overloaded.
The masonry of the external bearing walls is carried out by the links of the "four" masons. Recommended composition of the link (Fig.12):
Work on brickwork of external load-bearing walls is performed in the following sequence:
- marking of places of walls, doorways and their fixation on the floor;
- installation of rack - order (if necessary) (Fig.13);
- tensioning of mooring cord (Fig.14, 15);
- feeding and laying of bricks;
- overblocking, spreading and leveling of masonry mortar;
- laying of construction bricks (Figures 16, 17, 18, 19) in the structure of the outer wall;
-Verifying the correctness of laid masonry (Fig. 20);
- installation of prefabricated reinforced concrete lintels above door and window openings in the course of masonry.
Work on the construction of external walls by a bricklayer link is carried out in the following sequence. Masons K and K conduct masonry of the outer verst. Bricklayers K K make masonry of the inner verst and dam, while the bricklayer K helps them. The mooring cord is pulled by the bricklayer K only for masonry of the outer verst.
Masonry of external load-bearing walls is carried out from the inter-storey floor in a stepped way: first, masonry of the external verst is laid out in the 2 3 row, and then the internal structure of the wall. Masonry is carried out to an elevation of 1200 sound1250 mm above the floor level. Upon reaching the specified elevation, masonry continues with hinged panel scaffolds installed on the floor. Solution is spread on wall with indentation from edge of external or internal verst by 2-3 cm during masonry into wasteland and by 1-2 cm during masonry into clipping. When laying stamen rows, the dilution width of the solution should not exceed 22 cm, and when laying spoon rows-8 cm. At the same time, the vertical seams of the underlying masonry row are also filled with the solution. The height of the dispersed solution should be 2-3 cm so that after laying the brick there is an even seam of the required thickness. When laying a spoon row, the solution should be spread with a side face, and when laying stamen rows - with the front edge of a bucket-shovel. During masonry, the solution is laid in a "trough" formed by two vertical rows of masonry, and leveled with the rear of the shovel ladle. Masonry must be carried out in a wasteland with no masonry solution filling the front and inner surfaces of the walls up to 15 mm.. Horizontal reinforcement of masonry of external walls is performed by welded metal grids made of reinforcement wire every five rows.
During masonry breaks, the materials and articles laid in the structure must be closed from atmospheric precipitation.
.
Work on masonry of internal load-bearing walls and partitions is performed in the following sequence:
- marking of places of walls and partitions, doorways and their fixation on the floor;
- installation of rack - order (if necessary);
- tensioning of the mooring cord;
- feeding and laying of bricks;
- overblocking, spreading and leveling of masonry mortar;
- laying of bricks in the structure of the inner wall and partition;
- check of lined masonry correctness;
- installation of prefabricated reinforced concrete lintels above door openings in the course of masonry.
Masonry of internal bearing walls and partitions is carried out by the links of masons "double," the recommended composition of the link (Fig. 21):
bricklayer K strengthens the quay for masonry, bricklayer K feeds and spreads the brick onto the partition and spreads the mortar for masonry.
The berth is pulled along each row of masonry. Brick along the erected wall and partition is laid out in stacks of 2 pcs with an interval of 1/2 of stone (125 mm). Masonry at the intersection of structural walls, walls and partitions must be carried out simultaneously. In case of forced breaks, masonry is performed in the form of an inclined or vertical stroke. In case of vertical cutting, reinforcement consisting of three steel bars with diameter of 8 mm is laid in masonry seams after 2 m in masonry height, including in the level of each floor
Masonry reinforcement shall be performed every 4 rows of brick 2 W 6 A I. Masonry shall be wasteland with unfilled masonry mortar on the front surface of partitions up to 15 mm. When masonry reaches the elevation of 1200-1250 mm above the floor level, scaffolds are installed, and masonry of the next tier is carried out from hinged-panel scaffolds. The verticality of the faces and angles of the masonry, the horizontality of its rows should be checked at least twice on each tier of masonry (after 0.5-0.6 m) with the elimination of the detected deviations during the construction of the tier.
The laying of any structures and their elements, as well as the laying of bricks under the supporting parts of the structures, regardless of the dressing system, should be started and finished with a stamen row. The thickness of horizontal masonry seams shall not be less than 10 and not more than 15 mm. Thickness of vertical seams is assumed to be 10 mm
In the process of masonry, on each side of the door and window openings, at a height of 1/3... 1/4 the opening from the bottom and top of it, wooden antiseptic plugs are installed in the masonry (their size is usually equal to the 1/2 of brick) for subsequent attachment to them filling.
Prefabricated reinforced concrete lintels above window and door openings are installed with their supply by crane to prepared mortar bed. When installing jumpers, attention is paid to the accuracy of their installation by vertical elevations, horizontality and size of the support area.
Masonry is carried out in belt (two tiers on the floor). Construction and installation works are carried out in-line by areas and levels, which makes it possible to combine construction and installation processes and other works in time. Such method ensures continuity of installation works.
The floor is covered only after the installation of partitions, installation of window and door blocks, as well as the supply of materials for the construction of floors and sets of electrical and plumbing materials.
1.2.3. Instructions for installation works.
Prefabricated structures of the above-ground part of the building can be installed with supply from an acquired warehouse or from vehicles. During installation of prefabricated structures with supply from the acquired warehouse, all parts on the construction site should be stacked in the area of the tower crane. When organizing an acquired warehouse, it is necessary to plan and seal the site for storing products. The acquired warehouse is located in the area of the installation crane, and surface water is discharged. Heavy structures should be placed closer to the mounting crane. It is recommended that all structures, parts and articles be placed close to their installation in the design position in such a way that they are convenient to sling, and the marking is visible from the side of the passage. All structures stored in stacks shall be laid on wooden linings and gaskets (sheet No. 1). The installer of structures of the 2nd category prepares the elements for installation, slings them, using a four-branch sling with a lifting capacity of up to five tons (sling diagrams - sheet 1), for supply to the installation site, having previously examined and made sure that the elements are serviceable. The installer of structures of the 4th category accepts structures and together with the installer of structures of the 3rd category sets them to the design position, fixes and disassembles them. For installation of elements of reinforced concrete structures it is necessary to use inventory load-grabbing devices (sheet 1).
When laying slabs, special attention should be paid to the flatness of the ceilings and ensuring the necessary area for resting the slabs on walls. Before installation of floor slabs, support part of wall surface is checked and aligned at level of ceiling of underground. The first slabs of the inter-floor slab are laid from the same floor scaffolds that are used for the installation of wall structures. Subsequent elements are mounted directly from previously installed ones. One of extreme plates is laid first, for which scaffolding is used. Extreme slabs are installed with fencing structures attached to them.
Floor slabs are laid on a layer of M100 cement mortar. The stacking of the slabs is started from the end of the house, and then all the slabs are sequentially laid. The seams between the slabs, as well as the seams in the places of adjoining the walls, must be cleaned of construction debris and carefully poured with cement mortar of at least "150," about which to draw up an act for hidden work. In the place to make seals of concrete M - 200 with installation of fittings. Due to the small amount of welding work, the 4-bit structural installer, having the certificate for the right to work as an electric welder, performs electric welding of anchor joints. After laying of slabs and mineral felt, constructors pour seams between slabs with cement mortar.
Window and balcony door blocks must be delivered to the construction site glazed. Filling of window and door openings, hemp of boxes and installation of sill slabs is carried out in the course of masonry.
1.2.4. Crew calculation.
The construction of the building is carried out in-line, providing for the division of the building into two grips. The calculation of the team for the performance of a separate type of work is carried out in accordance with the ENi R for each of these types of work. Then, a complex team is assembled from the links performing each individual type of work. Work on the construction of walls and the installation of reinforced concrete elements of structures is carried out by a team in the following composition:
First shift:
4-bit mason - 8;
2-digit mason - 8;
2-degree rigger - 4;
driver of valve (5) - 1.
Second shift:
4-bit installer - 1;
3-bit installer - 2;
2-bit installer - 1;
5-bit carpenter - 1;
3-bit carpenter - 1;
2-degree rigger - 2;
driver of valve (5) - 1.
The number of divides on capture is taken according to the number of links in the brigade. When calculating the size of dividers, they proceed from the condition that for a change, the link should lay the wall to the height of the tier (1.1-1.2 m) along the entire length of the divider. The size of the plot (length of the work front) is determined by the formula:
On one capture, 4 plots are organized.
The main working processes are reduced to four complex ones - brickwork, lifting mortar and brick to the workplace, rearranging scaffolding, installation and related processes.
The duration of masonry on the floor is associated with the crane operation time in days with its two-shift use. The planned time is 8 shifts, or 4 days of work.
When erecting a floor, it is divided into two grips along the longitudinal axis of the building, and work will be carried out simultaneously on two grips. On one, walls are laid to a floor height of two tiers, on the second - the installation of prefabricated structures and other works accompanying masonry. The masonry of the walls on the floor begins on the first grip with the longitudinal axis that is further from the installation crane.
Leading process - brickwork is performed in 1 shift, rearrangement of scaffolding, supply of materials, installation, related work - in 2 shift. The duration of the gripping works depends on the labour intensity of the crane processes when loading the crane in 2 shifts; numerical composition of masons is determined by dividing the total labor costs by masonry by the accepted duration of work.
1.2.5. Tools, accessories and equipment.
Tools and equipment used in operation shall comply with the standards (specifications), be convenient, strong, safe for others and be kept in good condition (Fig. 22, 23, 24, Table 3).

1.6.Technical economic indicators.
Schedule
2.1. How to build a schedule.
The construction schedule is a documented model of construction production, which establishes the rational sequence, sequence and timing of individual works and construction processes at each site.
The purpose of calendar planning is to develop and implement the most effective model of organizational and technological linkage of work in time and space on one facility, performed by various executors with continuous and effective use of labor, material and technical resources allocated for these purposes in order to put the facilities into operation within the specified time frame.
The object schedule is designed to establish the composition and number of construction and installation works at the facility, the order, sequence and timing of each work, as well as to determine the dates for the start and completion of the construction of the facility (SNiP 3 01 - 01 - 85).
The initial data for the development of the object construction schedule are:
- standards of construction duration of buildings and structures (SNiP 1 - 04 - 03 - 85);
- detailed documentation of architectural and construction part of the course design;
- data of engineering surveys of the construction site;
- typical PPM of similar objects;
- typical Job Instructions for execution of main processes and operations;
- SNiP 3 - 4 - 80 "Safety in construction";
- Bill of quantities of work;
- Labor cost statement (compiled on the basis of SNiP 4 - 02 - 91 and SNiP 4 - 05 - 91);
- a process plan developed for the construction of the first floor.
The schedule for the construction of the facility is developed in such a sequence: an analysis of the space-planning and structural solutions of the facility is made in order to choose rational methods for its construction; a list of construction and installation works included in the calendar schedule is established; count the number of construction and installation works included in the list; the labour intensity of each work (human days) and the need for construction machines for each work (machine shifts) are determined. Methods of work execution and means of mechanization are selected, sequence of work execution is established, and possible combination of different types of work, taking into account production in-line method. The duration of each work is determined based on their labor intensity; deadlines for commencement and completion of works according to the calendar are established; on the basis of the calendar plan, work schedules of workers, work schedules of the main construction machines are drawn up; Health and safety measures are planned.
The development of the schedule is carried out in accordance with the following principles:
1. The construction period must not exceed the standard construction period, this is determined by the coefficient of construction duration. Construction duration shall not depend on special works. Special requirements for site commissioning dates are taken into account.
2. When developing a work schedule, it should be linked taking into account the technological sequence and labor protection requirements.
3. Climate and environmental factors should be taken into account.
4. Machinery downtime, short-term workforces, and drastic reductions in workforces should be avoided.
5. The design documentation is reviewed.
6. Nomenclature of works to be included in the schedule is determined.
7. The scope of work is calculated.
8. Selection of work methods and main machines and mechanisms is made.
9. You define the work for the individual activities.
10. Work duration is calculated and schedule is built.
11. Work and machinery movement schedules are built. The sequence and duration of works are established.
12. Optimization of the schedule is carried out in accordance with the schedules of the movement of workers and mechanisms. It is checked that the scheduling for the process sequence dates is correct.
The work schedule shall be prepared according to the established form. The left part includes the initial data: the list and number of works, labor costs, construction machines, the duration of work in shifts, the number of shifts in days, the number of workers per shift, the number of cars per shift, the composition of the team. In the right part: which is a schedule of work, show the progress of construction and installation works with the indication of the sequence, the timing of each work, the number of employed workers, the shift of work. The due dates are linked to the calendar that is placed at the top of the schedule. The duration of the work is shown in the graph in a solid line if the work is performed in one shift, and in a double solid line if the work is performed in two shifts. The numbers above the line indicate the number of workers involved in this work, the number of shifts and the duration of the work
The schedule for the movement of workers is built directly under the schedule and on the basis of its data on the quantitative and qualitative composition of specialized and complex units and teams.
The workers' movement schedule is constructed by summing up the number of all workers on each working day in all the work that takes place on that day. At the same time, differences, peaks and other sharp fluctuations in the number of workers are inevitable in the graph. It is necessary to achieve a minimum number of such fluctuations. To this end, the previously drawn up calendar plan is clarified and improved, that is, optimized.
Uniformity of use of labor resources of calendar plan is estimated by coefficient of uneven movement of working personnel.
The schedule of demand for construction machines is drawn up in the form of a table under the schedule in close relationship with the construction schedule.
The graphic part reflects the technological relationship of all types of work and determines the duration of each construction process, as well as construction in general. The nomenclature of works covers zero cycle, installation work, stone, roofing, finishing work, special types of work, landscaping.
Commencement of construction according to the calendar plan on April 1, 2010.
Completion of construction May 26, 2010
For this schedule:
The actual construction duration is 38 days, the standard construction period is 39.3 days. Duration factor - 0.97,
- construction period does not exceed the normative construction period;
The total labor intensity for the main construction and installation works is 476.2 people, the average number of workers at the construction site is 18.63.
In accordance with the schedule, a schedule of workers was built, the schedule was optimized for the distribution of workers and the unevenness coefficient of workers was calculated.
The maximum number of workers at the construction site is 26 people. The unevenness coefficient of the movement of workers is 1.4.
2.2. Methods of works execution.
The main factor determining the decisions of the work schedule is the method of their organization.
In practice, various methods are used, differing in the presence of various restrictions and a system of rules for the interaction of the resources of construction organizations, ensuring the achievement of a given result - the effective performance of construction and installation work at a given time without reducing the volume of production or provision of services.
In order to achieve this goal, the planning for the construction of industrial enterprises or civilian facilities should be based on the main strategies presented by typical construction organization schemes.
The parallel method of organizing construction involves simultaneous construction and installation work at all facilities and sites. This method allows the construction of the facility to be carried out in an extremely short time, but its use is possible only with the maximum concentration of resources of the construction organization.
The sequential method of organization of work has various modifications, in which the work is carried out alternately, in individual areas of the object (workshops, premises, buildings). The sequential method ensures the shortest duration of construction in individual areas, which leads to the rapid commissioning of the area until the completion of all work on the facility. However, the total duration due to the usually large number of queues is significantly increased, and the resources of the construction organization are used least rationally due to the need for frequent transitions of construction machines and workers from one site to another. With a consistent method, it is also necessary to make up for the losses of products or services provided, but the amount of reserves can be significantly reduced.
The most rational in-line methods of organizing construction, combining consistent and parallel organization of work.
The flow method best meets the requirements of the construction organization, since it can use its resources sufficiently rationally.
Before the start of earthworks at the construction site, a set of preparatory works is carried out: marking and releasing the diversion strip from trees, shrubs, turf cover, slabs, stones, boulders; surface water discharge device, geodetic survey works.
Earth-moving and earth-moving vehicles are used in earthworks. The planning of the territory of the construction site and cutting of the vegetation layer are carried out using a bulldozer, which works in a layer-by-layer manner with the movement of soil at a distance of up to 100 m. Soil backfilling is also carried out using a bulldozer. Soil development in trenches is carried out using a single-bucket excavator with loading on dump trucks and in a dump. Rework of the pit bottom is performed manually to a depth of 0.07 m (SNiP 3 - 02 - 01 - 87).
By means of the assembly crane of the KS brand - 8362A all installation works are performed. All these works are performed by a team of eight people, including the crane driver.
Installation of tape foundations is carried out as follows:
- The breakdown begins with the transfer of the axes of the building to the base.
- Installation of foundation cushions starts with laying of corner, i.e. lighthouse, as well as intermediate lighthouse blocks. Installation of foundation cushions is carried out by means of a "canopy" by a tower crane.
- After laying of the whole series of foundation cushions, their position is checked using theodolite or leveler.
- Subsequent rows of tape foundation are mounted similarly.
Waterproofing of the foundation is carried out as a continuous waterproof rug made of ruberoid, glued in two layers on the insulated surface.
For the productive work of bricklayers, it is essential to organize the supply of materials to workplaces and for this, a boom crane is used on the construction site. The brick is supplied to the workplace with bags on pallets. Masonry solution is supplied by crane in boxes..
All types of prefabricated flat floor elements are mounted in a "canopy" manner.
The elements can be stacked in the warehouse in the crane area or transported from the plant. Depending on the size of the slab elements and the number of places of their capture, a four-branch sling is used as sling devices. Universal load-gripping device can be used for mounting with simultaneous horizontal position of plates.
The first slabs of the floor slab panels are laid from the same floor scaffolding that wall masonry is used. Subsequent plate elements are laid directly from previously laid elements. Extreme plates are laid with fencing structures attached to them.
Window and door blocks in buildings are installed before the start of finishing work. Door blocks are installed in the opening before the start of finishing work, but door webs are removed for the period of finishing work. Window and door blocks are installed in openings during the construction of walls, using mounting mechanisms available on the object for this purpose.
The work on filling the openings is carried out by a team of working carpenters consisting of two people.
Roofing works in KP are planned after installation of the building box in order to create a work front for finishers.
Before installation of the rafter system, perform the following organizational and preparatory measures and works:
- make and accept the underlying structures, including installation of attic slab, cornice arrangement, installation of ventilation risers above attic slab and roof;
- install lifting crane or equipment;
- prepare tools, accessories, equipment;
- deliver materials and products to the workplace,
- issue a work permit for high-risk work;
- familiarize the performers with the technology and organization of works.
Preformed, treated with protective compositions, marked and spacketed elements of rafters system are supplied to attic floor. At the same time, inventory scavenging means for mounting are supplied.
Installation of rafter system elements from inclined rafters is performed with breakdown of work front for gripping in the following order:
- Install mauerlats and sunbeds;
- racks and skate runs are installed;
- installation of rafters' legs and braces;
- a lattice is installed.
Installation of mauerlates and sunbeds is performed with preliminary laying on top of walls of 2 layers of roll waterproofing.
Work is carried out in summer conditions in one shift.
Plastering of surfaces during the construction of an object is carried out by a flow-dissected method, which is based on the breakdown of processes into separate operations performed by specialized units that make up a complex team. The links, their number, composition and scope of work are selected so that the rhythmic transition of workers from one grip to another is ensured and all work is carried out in a continuous flow. At the same time, plaster work in the building can be carried out "from bottom to top," i.e. as the floors are ready, with the condition that there are at least two laid floors above the plastered floor; or "top-down" when plaster work begins after the building is completed. When erecting the volume for plastering, a team of plastering workers consisting of 21 people is occupied, which are distributed among the works being carried out, as follows: 5 workers apply spray, 5 workers apply soil, 5 workers apply cover with rubbing of the surface with a half-cloth, four workers fill the surface, two people ensure continuous operation of the plaster station.
Before starting painting work in the premises, it is necessary to complete all construction work (except for the installation of clean floors), electrical work, sanitary and technical. Before painting, the humidity of the plastered surfaces shall not exceed 8%. Wooden structures, as a rule, come to objects painted at one time. To perform painting work at the facility, a team of five painter workers was adopted. The organization of the team's work was built in-line, i.e. the entire volume of work is divided into captures and molar works are carried out on captures and on the campaign of the main works.
The building has three types of floors: ceramic tiles (in bathrooms), covered with linoleum and parquet. Before floor arrangement base is cleaned from building debris and washed with water. Cement sand mortar is used as bracing. Floors are arranged on a pre-prepared base, in accordance with typical job instructions for each type of work.
The arrangement of the floors is carried out by a team of eight people. Work should be started after completion of work on previous grips during floor preparation during work.
The improvement of the territory is carried out by a team of three people and lasting 9 days, work is carried out in one shift. They clean up the territory, landscaping, the construction of sidewalks, roads for the entrance of transport, the construction of a playground.
When the facility is commissioned, a commission is created, which is presented with acts, drawings, work logs, author's supervision logs.
The Commission shall check the documentation, quality and conformity of the performed works to the project, readiness of the handed-over facility, including all previous works. Then draws up the corresponding act, which serves as the basis for the appointment of a state commission.

4) Height position of frames or boards is determined by leveling and set to design elevation.
5) The sand cushion is pressed and leveled to the level of the frame or boards.
6) Blocks are installed on the prepared base so that their main marks coincide with the marks of frames or boards.
7) Check the position of corner and beacon blocks by leveling (in this case, the counter on the rack standing on the block should be less than the counter on the rack at the reference point by the block thickness).
8) Control planned measurements of sides and diagonals in sections limited by corner and lighthouse blocks are made and compared with design dimensions;
9) At the level of the upper outer rib of the corner and lighthouse blocks or between the lighthouse blocks, the berth is pulled and the installation of other blocks is controlled along it, filling the gap.

The most frequent defect in the arrangement of tile floors is the detachment of tiles from cement mortar laid on a dry concrete base. Due to intensive suction of moisture from the interlayer by the base, the strength of the solidified dewatered interlayer is reduced, and its structure under load is disturbed, which leads to partial or complete detachment of the tile coating.
Similar defects in tile floors are observed with intense exposure to the freshly lined surface of the sun's rays and excessive heat in the rooms, especially with minimal water content of the grout interlayer.
The tiles can also peel when the interlayer is not uniformly varied in volume, if fatty compositions of the solution are used, or when its thickness varies significantly.
Often, the reason for delamination is the laying of dusty tiles, insufficiently thorough cleaning of the base from dust.
In case of partial or complete peeling off of the floor coating, the tiles and interlayer are removed with a tooth and a hammer, the base surface is cleaned, provided with dusting, wetted with water and again lined with tiles.
When arranging interlayers and ties, their thickness should be carefully checked, taking into account the thickness of the coatings, so that after laying the tiles, a single floor level is maintained in all rooms.

3. 1. General Plan Principles.
The construction plan is the most important document regulating the organization of the site and the volume of temporary construction.
The initial data for the construction master plan design are:
Architectural drawings of the object - floor plan, section, master plan.
Methods of works execution.
Construction schedule.
The course project has developed an object construction master plan.
The main purpose of the construction plan design is rational placement of the main installation mechanisms, temporary buildings, structures and installations.
The construction plan consists of a graphic part and a calculation and explanatory note. Graphic part of the construction plan: outline of the building under construction;
lifting and mounting mechanisms for their movement, as well as platforms for their installation and dismantling;
crane and hazardous areas;
building materials and parts warehouses and pre-assembly sites;
temporary and permanent roads and engineering communications;
placement of temporary administrative, domestic and industrial premises;
boundaries of the construction site;
explication of temporary buildings and structures, conditional images.
The need for manpower and material resources is determined on the basis of the calendar plan; based on the calculation of resource requirements, types and number of temporary buildings and facilities; site boundaries are applied on the plot plan; Temporary building locations; the outline of the building under construction, engineering communications and roads.
In the explanatory part, on the basis of the selected methods of work, storage areas are calculated and construction warehouses for open storage of materials are placed; design on-site roads and access roads (including temporary ones); calculate temporary administrative buildings and structures, select and place them on the construction site; placing closed storage warehouses; calculating and designing external lighting of the construction site; determining electric power consumers, their location and power; determining heat consumers and designing a heat supply system; determining water consumers and calculating a water supply system; calculating and designing a system for providing the construction site with compressed air, communication and dispatching networks; building site fencing is designed.
The construction of a two-story brick residential building for two apartments in Kashira is carried out on a territory free from development. The construction site is enclosed by a continuous concrete fence 2.4 m high. The site has a gate for entry and exit directly to the intra-quarter road and beyond.
The main working road on the construction site is permanent, has a site for unloading vehicles and is designed from road slabs 3.5 m wide. The road is looped, there are sites for the junction of transport; in storage areas there are widens up to 6 m, at the points of turn of transport the road has a rounding radius of 10 m. Roads are equipped with signs, traffic patterns and road signs are posted at the entrance to the construction site.
During the construction of a residential building, a lifting mechanism is used - a boom crane of the brand.
Crane operation area is determined by installation area, dimensions of which are designed according to maximum boom flight.
On the construction master plan, a hazardous zone has been designed for - an area where people are found dangerous to health and life due to a possible break in moving cargo - this is a high-risk zone.
The dimensions of the hazardous area are determined by the possible departure of the cargo when it falls from a height, and are determined by the formula:
Rospass zone = 0.3 × Building
We accept the dimensions of the danger zone - 2 meters.
Temporary buildings and structures are accepted according to the calculation taking into account the construction master plan for the specified work cycle.
At the entrance, household premises are designed from mobile cars for servicing workers, the paths of workers do not cross heavy traffic and the danger zone.
Temporary power supply, water supply and sewerage are accepted taking into account the number of people working on this cycle, the number of temporary buildings and structures, the technology of conducting certain types of work.
Toilets, dressing rooms, showers and a food tub are provided with water from the city water supply, sewerage is carried out directly to the existing city sewage collector. Heating of domestic premises is provided by electric heating devices. The telephone service of the foreman's office is provided from the existing telephone network.
For power supply of the construction site, a transformer substation is provided, which is supplied from the intra-quarter substation with high-voltage cable. A chopper for connecting consumers is installed, electric power is supplied from it by a separate cable to household premises, and for lighting the construction site.
A fire shield with fire fighting equipment is equipped on the site and hydrants are installed that connect to the city water supply.
Materials and products are stored in the crane service area.
3.2. Calculation of the area of temporary buildings.
The need for construction in administrative and sanitary buildings is determined on the basis of the calculation of the number of employees according to the standards. The number is determined according to the calendar, according to the schedule of movement of workers.
The share of categories of workers (workers, ITR, employees, junior maintenance personnel, security) is accepted approximately in% of the total number of workers: workers - 85%; ITR and employees - 12%; MOS and security - 3%. All these buildings are designed for all employees, including subcontractors, without exception.
Maximum number of workers from the work schedule: Rmax = 26 people.
Engineers and technicians
employees: ITR = 0.12 × 26 = 3 people.
Junior maintenance personnel and security: MOS = 0.03 × 26 = 1 person.
Number of employees: R = 26 + 3 + 1 = 30 people.
Domestic premises on the construction master plan shall be designed in compliance with the following conditions:
Household premises are grouped and located in one place;
Groups of domestic premises are designed near the main entrance to the construction site;
In accordance with safety procedures, domestic premises are located outside the hazardous area;

- open (prefabricated railway, brick, etc.);
- open and semi-closed canopies (carpentry, process equipment)
- closed insulated and non-insulated (cement, ruberoid, paints, etc.);
- special (combustible and flammable liquids, etc.).
Closed warehouses are non-inventory and inventory (prefabricated, container, mobile).
When designing the acquired warehouses, determine the necessary stocks of material and technical resources to be stored in the warehouse; purchase warehouses by storage type; Determine the storage type location and binding of the warehouse on the construction site.
Open warehouses of materials and structures are located near objects under construction and in the area of operation of mounting cranes along the front of their movement.
The following types of warehouses shall be provided at the construction site:
- closed: for storage of binders, paints, lacquer, chemicals, glass, linoleum, tiles, ruberoid, etc.
- canopies: for storage of reinforcement, window and door blocks, wood products, etc.

Rooms shall be provided with harmless detergents and warm water.
It is forbidden to heat and dry the rooms with roasters and other devices that release fuel combustion products into the rooms.
When performing work with solutions having chemical additives, it is necessary to use personal protective equipment (rubber gloves, protective ointments, protective glasses) according to the manufacturer's instruction of the composition used.
In case of dry cleaning of surfaces and other works related to dust and gas release, as well as in case of mechanized patching and painting, it is necessary to use respiratory devices and protective glasses.
When cleaning surfaces with acid or caustic soda, it is necessary to work in safety glasses, rubber gloves and an acid-resistant apron with a breastplate.
Use safety goggles when applying the solution to the ceiling or vertical surface.
3.6.4 Fire safety at the construction site.
Fire-fighting measures are performed during the entire period of construction works.
First of all, appropriate fire resistance of building structures for various categories of buildings and structures should be ensured.
To prevent a fire, fire barriers are arranged on the building - firewall walls, having a fire resistance rating of at least 4 hours. Firewalls are on independent foundations, cut vertically all structural elements of the building and must rise above the roofs by at least 0.6 m. In wooden buildings, firewalls must still protrude beyond the outer walls, eaves and overhangs of roofs at 0.3 m. Doors in firewalls are installed unburned, with fire resistance of at least 1.5 hours, and the area of openings should not exceed 0.25% of the firewall area.
In firewalls it is allowed to arrange ventilation and smoke channels.
Protection of wooden structures from fire can be carried out by painting with special fire-retardant paints, impregnation in solutions of special salts, the creation of thin-layer coatings and thermal odors. Fire-retardant coatings make fire difficult and slow the spread of fire. Fire retardant paints are applied with brushes or paint. Paints containing clay are applied with a molar brush, with a passage of at least 3 times. Coating with fire-retardant compositions is applied by hand protected with sleeve made of tight tarpaulin. When small cracks appear on the coating after drying, secondary coating is performed with a thinner layer and a more liquid solution. The thickness of the coating should be 2... 6 mm.
Fire-retardant works begin with sealing of cracks with pins. Fire retardant composition: 1:2... 3 (clay: sand), 1:2: 0.3 (clay: sand: gypsum). After drying, fire-retardant painting or coating is made.
On construction sites, roads and driveways should not be cluttered with building materials and equipment, each utility or main building and structure should not be located from roads and driveways at a distance of more than 25 m. At night, roads and driveways on the construction site, the locations of water sources and fire stations should be illuminated. Timber is stacked, making fire breaks from buildings under construction or temporary structures in 15... 30 m.
Burnt building materials, chips, sawdust, etc., must be removed daily to specially designated places at a distance of at least 50 m from timber warehouses, buildings and structures.
Warehouses of flammable and combustible liquids, varnishes and paints, depending on their capacity and storage method, are arranged with fire breaks in 18... 36 m. Household premises are arranged with fire breaks of 5 meters. It is forbidden to contain flammable and combustible liquids in the basements and floor of the basements. During storage of varnishes and paints, the greatest fire hazard is dissolved in olefins, whitespirite, alcohol, etc.
It is allowed to store gas cylinders in special closed warehouses and in open warehouses under canopies with fire breaks of at least 20 m, with a distance to warehouses with flammable and combustible liquids of at least 50 m. The territory of the open warehouse should be protected. Do not store oxygen cylinders and cylinders with combustible gases in one room. Filled and empty cylinders shall be kept separately. Cylinders for different gases shall have a distinctive colour and an inscription indicating the gas. Cylinders with safety valves are stored and issued. In the room, cylinders with combustible gases from heating radiators are installed at a distance of 1.5 m.
Lime quenching pits are located at a distance of at least 5 m from the place of its storage and at least 15 m from other buildings and structures. Unburned lime shall be stored in closed non-combustible storage rooms with raised floor above ground level not less than 20 cm. Use of water and foam fire extinguishers in these warehouses is not allowed, dry sand and carbon dioxide fire extinguishers should be used. Temporary wiring on the construction site is performed with insulated wire on strong supports at a height of at least 2.5 m above the workplace, 3.5 m - above the passageways and 6 m - above the driveways. Suspension of wiring at a height of less than 2.5 m is allowed only in pipes or boxes. Electric lamps of general lighting are used 127 and 220 V when the luminaires are located at a height of at least 2.5 m, at a lower height of the luminaires, an electric current voltage of not more than 36 V should be used.
Construction sites shall be provided with primary fire extinguishing equipment.
The fire department includes:
• Fire extinguisher - 2 pcs
• Shovel -2pc
• Buckets - 2pc
• Sand box 0.5 m3
• 250 liter barrel with water
• Bagor -2pc
In order to quickly notify the fire and call the fire department, the construction site should have a telephone connection.
3.6.5. Analysis of hazardous and harmful factors of the construction site.
Construction as a branch of the national economy requires the implementation of sufficiently complex and diverse organizational and technological decisions in the process of preparing production and at the stage of its implementation. The specific features of construction are characterized by the variability of the place of work, the relative shortness of technological processes, the use of various construction machines, units, devices, the need to work outdoors, often in adverse weather conditions. This puts forward increased requirements for creating and ensuring safe and healthy working conditions at work, improving technological processes and implementing labor protection measures in construction. The analysis of the causes of industrial injuries makes it possible to identify them in the main groups:
- organizational - poor organization of work on the construction site, insufficient training of workers, formal training and instruction on labor protection, violation of production technologies, violation of the work and rest regime, use of workers not by specialty and without taking into account qualifications;
- technical - faulty condition of scavenging facilities, accessories and tools, structural flaws of construction machines, units, equipment;
- sanitary - poor lighting of workplaces, dust content of air, vibration, absence or insufficiency of domestic premises, etc.
- psychological and physiological - lack of attention, weakening the control of workers over their activities (unnecessary risk, work at height without a mounting belt, etc.).
Any of these causes may cause an emergency, resulting in injuries, fatalities and material damage. The most common negative situations on the construction site include the collapse of forests, the fall of mounted elements as a result of a sling of slings and loops, the collapse of soil from the slopes of excavations, falling from a height due to the lack of fences, electrotraumatism, fires in sanitary facilities. The need to work with caustic and toxic substances (varnishes, solvents), with pulverized materials, with vibration tools leads to skin diseases and lung diseases. Working at low temperatures in a humid environment, with large physical loads, leads to a disease of the joints and musculoskeletal system.
3.6.6. Measures to ensure safe working conditions.
Prior to commencement of construction and installation works in the territory of the organization, the producers of works and the administration of the operating organization shall issue a certificate, and after completion of the works of the preparatory period - an act on compliance of preparatory works with the requirements of labor safety and readiness of the facility for the start of construction.
The site itself, being a high-risk zone in urban development, is fenced with a fence 2.4 m high. The height of the fences of the work sections is 1.2 m. When the fence adjoins the place of passage of people, the fence is made with a visor. Workplaces and passages to them at a height of more than 1.3 m and a distance of less than 2 m from the height difference boundary are protected by protective fences, and at a distance of more than 2 m - by signal fences. Openings in the walls when one-sided adjoining them are protected if the distance from the floor level to the bottom of the opening is less than 0.7 m. The entrance to the building under construction is protected from above by a visor 2 m wide at an angle of 7075 ° from the wall.
If the workplaces are not protected, then the installers work with a permit and safety belts.
The underground part is erected by a self-propelled crane MKG20. A hazardous area is determined at the site, which is 13 m taking into account the longest mounted element with the addition of the minimum departure distance, determined depending on the height of the building (according to SniP 12032001). At the border of the hazardous area, signal fences and safety signs are installed (area near the building, area of construction machines). Sanitary facilities and passages to them are located outside the hazardous area. It is forbidden to be on the site without a helmet. The above-ground part is installed by BKSM5 tower crane. When working on the lifting crane site, a person responsible for cranes and rafters is appointed. All of them undergo training and certification at the courses of Gosgortekhnadzor, have a certificate. Slingers and crane operator under the receipt shall be informed with the PPR (Stroygenplan). On the construction plan, parking lots, crane operation area, control cargo location and crane parking place during inspection are indicated, slinging diagrams are developed. The crane operator performs only the commands of the rafters, which have distinctive signs (helmets different from the working color), clearly visible from the crane. The Stop command is accepted from anyone. When the cargo installation site is out of sight of the crane operator, an intermediate signalman is used. The crane operator must have a table of weights of mounted elements. During operation of the tower crane, crane tracks are arranged, grounded, protected and accepted by act. The work is carried out in accordance with the Rules for the construction and safe operation of lifting mechanisms.
Materials are stored on liners and gaskets on specially designated planned sites with a strong base. Structures and materials are stored in accordance with the requirements of SniP 120399, leaving passages 1 m wide between stacks. It is not allowed to lean materials and structures to fences, trees and temporary structures.
Wiring of temporary networks is performed by isolated wires on strong supports at a height of 3.5 m above the passages, 6 m - above the driveways, 2.5 m - above the workplaces. Areas of work and the site as a whole, workplaces, driveways and passageways in the dark are illuminated by floodlights. There should be no blind action of instruments. The choppers are in protective design, the distribution board - with a locking device. The network is served by a duty electrician. Metal scaffolds, fences, crane tracks, electrical equipment enclosures are grounded.
Safety requirements for performance of various types of works are developed in accordance with SNiP as part of Job Instructions. All workers undergo induction training before the start of work, and in the aftermath of work - periodic training at workplaces with subsequent certification.
Sanitary facilities at the site are accepted based on the number of people at the site during the design period.
The concentration of harmful substances in the air of the working area, noise and vibration levels at workplaces should not exceed the established GOST.
The compliance of working conditions with hygienic standards is monitored during the certification of workplaces. Workers engaged in work with harmful working conditions are provided with protective equipment and are additionally instructed. The site area is equipped with fire extinguishing equipment according to fire safety rules: sand boxes, fire hydrants, fire extinguishers. On the shield there are: a shovel, a bucket, an ax, a trunk, scrap. The shield is located near domestic premises. Special places are allocated for smoking and fire hazardous work (within a radius of more than 50 m from places with combustible materials). Cylinders with combustible gases, combustible liquids are stored separately in ventilated rooms with fire extinguishing equipment and insulated wiring. Places for heating bitumen and other works are removed from burned materials, warehouses with combustible materials. At workplaces where paints and glue that emit explosive substances are used, actions using fire and possible sparking are not allowed.
Domestic premises on the site are arranged with fire breaks. It is forbidden to use homemade heating devices in domestic premises.
All work related to artificial heating or heating at the construction site is carried out under the supervision of the duty electrician. It is forbidden to use roasters and other home-made devices to dry the premises.
Internal roads provide access to the building in accordance with fire regulations, traffic patterns and road signs are arranged at the entrance to the site. On the site there are warning signs, fire department phones. A wash is installed at the entrance to the site.
3.6.7. Environmental assessment during construction and mitigation activities
the environment.
When designing the organization of construction production, according to SNiP 3.01.0185, a list of special measures for environmental protection is provided for during the construction and operation of buildings.
Preservation in the process of construction of green spaces provided for by the project.
Carrying out during landscaping of the site of its landscaping.
Use of cut vegetal soil for site reclamation.
Control of carbon monoxide content in exhaust gases of construction machines, ingress of working liquids and lubricants into the soil.
Washing machines only in stationary conditions or specially designated places.
Waste disposal or disposal to landfills.
During the development of the site, the vegetation layer is cut and preserved until its subsequent use during the reclamation of disturbed land. Temporary buildings and structures should be located on unsuitable soils for land use.
Felling of trees and shrubs on the territory of the construction site is carried out only within the boundaries established by the design documentation. Trees and shrubs suitable for subsequent landscaping must be dug up and planted in a specially designated area. Land plantations that are not subject to cutting or transplantation should be protected.
Unused construction waste, including from the dismantling of existing buildings, construction debris is stored and exported.
Vehicles under unloading must be with the engine turned off.
Upon completion of the main work on the improvement of the territory and its landscaping, it is planned to form a system of green spaces that contribute to noise protection.
