Depending on the complexity of the object, the conditions for conducting construction work and socio-economic significance, items can be added, expanding, have a more unfolded structure.
In the staff, such aspects of construction and installation work, such as logistics, must be noted.
- safety and safety of labor;
- natural and climatic conditions;
- technical equipment;
- compliance with the norms of nature conservation;
- providing the object with communications and much more.
Only the deep knowledge of the specifics of the construction, repair and installation work, accompanying their documents and regulations, can ensure the compilation of a competent detailed design of the construction organization. And on this base, other documents, permits and tolerances will be formed. So, in particular, the project manufacturing project (PPR) is built on the basis of the PIT and contains, in fact, a step-by-step plan for working on each site of the object.
Thus, the construction organization project is a mandatory document, both for a contractor and for the customer, and for organizations that provide logistics in the construction facility that need to coordinate the parties and the final approval of state expertise.

Coordination of projects
Maintenance of the PIC in the examination and the Glavgosexpertization
Any construction of reliable, harmonious buildings and structures requires careful engineering calculation and professional planning of material, technical and labor costs. In accordance with the requirements of the legislation, the project documentation project includes a construction organization project. The significance of the PM emphasizes the fact that this document is subject to state expertise, on the basis of the decision of which is issued a permit for the construction of a fixed in the post.
Unlike a project for the production of works developed on certain construction facilities, the project organization of work covers the entire complex of buildings and structures at the construction site. Based on the master plan, several PPR are drawn up, in which the technological process is discussed in detail, the rational organization of construction and the expenditure of material and technical and labor resources for the construction of a specific object. Construction organization projects are developed as for entire residential microdistricts with a variety of infrastructure, large production complexes and for individual buildings and structures. The elements are necessary in the event that it is planned to consolidate or reconstruct objects. The construction project project is a mandatory document for the customer, contracting organizations, and organizations responsible for financing and logistical support for construction.

For residential buildings, a sequence of the construction of the building itself, outdoor engineering networks, improvement is presented. The following is a description of all listed works.
The technological sequence of work, installed by organizational and technological schemes, is the source material for the development of the calendar plan.
An example of a description of the work provided for in the project
(This example is not universal. The workset is adjusted in accordance with the technical solutions adopted):
Excavation
Earthworks must be performed according to the rules.
SP 45.13330-2010 "Earth structures, grounds and foundations."
During the construction of a residential building, earthworks begin with removing the fertile layer of the soil in a non-murosle state with moving it in temporary dump outside the removal zone. The cutting of the fertile layer of soil and the movement of the fertile layer of the soil is made by transverse and longitudinal passages of the bulldozer.
The dump should be located at a distance not closer to 0.5 m from the edge of the trench being developed to avoid its squeezing. When removing, moving and storing a fertile soil layer, it is not allowed to mix it with mineral soil, pollution with liquids or materials, erosion and blowing, as well as its use for filling.
When developing a trench, the excavator must be beyond the prism of the soil collapse (sloping) at a distance indicated in Table 1.
Table (table number) - the smallest distance from the base of the slop to the nearest supports
| Soil (not bulk) | With the depth of the excavation, m | |||
| 1,00 | 2,00 | 3,00 | 4,00 | |
| Table continuation | ||||
| Sand and gravine | 1,50 | 3,00 | 4,00 | 5,00 |
| Supaudea | 1,25 | 2,40 | 3,60 | 4,40 |
| Loamy | 1,00 | 2,0 | 3,25 | 4,00 |
| Clayey | 1,00 | 1,50 | 1,75 | 3,00 |
| Lesova dry | 1,00 | 2,00 | 2,50 | 3,00 |
When developing a trench by an excavator, the soil should be thrown away at a distance of at least 0.50 m on the brings of the trench (pit) in dry and related soils and at least 1.00 m in sand and moistened soils.
The trench with vertical walls without fastening is developed by a single-bonded excavator in the soils of natural humidity with an undisturbed structure in the absence of groundwater to the depth of no more:
In bulk sand and grave soils 1.00 m;
In sulesa 1.25 m;
In Suglinka and clays 1.50 m;
In particularly dense unknown soils of 2.00 m.
When digging trenches and recreation of greater depths, it is necessary to arrange the slopes of various embezzlement depending on the composition of the soil at the groundwater level below the depth of the excavation according to Table 2.
Table (table number) - permissible steepness of slopes of trenches
| Soils | Trench depth, m | |||||
| Up to 1.50 | 1,50-3,00 | 3,00-5,00 | ||||
| angle of slope, degree | bias | angle of slope, degree | bias | angle of slope, degree | bias | |
| Bulk | 56 | 1:0,67 | 45 | 1:1,00 | 38 | 1:1,25 |
| Sandy and gravel | 63 | 1:0,50 | 45 | 1:1,00 | 45 | 1:1,00 |
| Spring | 76 | 1:0,25 | 56 | 1:0,67 | 50 | 1:0,85 |
| Loam | 90 | 1:0,00 | 63 | 1:0,05 | 53 | 1:075 |
The development of trenches by a single-line excavator should be carried out with the elimination of scallops at the bottom in the digging process, which is achieved by pulling the bucket along the bottom of the trench after the development of a slaughter.
In the event of groundwater appearance, water-gravilization of incoming water from the watershedral (pit) followed by pumping the pump (piston, diaphragm or centrifugal, depending on the head of the incoming water) to the surface, where the water is removed from the drums or traders.
The soil in the pit is chosen without reaching the design mark - 10cm. The refinement of the soil is performed immediately before starting work on the foundation.
The soil for the inverse backfill of the trench sinuses and the pit is moved by a bulldozer 9 or automobiles from the reserve.
The backflow of trenches and sinuses should be made of mineral soil without construction debris, without inclusions of large debris (more than 50mm in diameter) of solid rocks (crushed stone, gravel, frozen closures) with layer-by-layer sealing pneumatic glasses and platforms.
Monolithic reinforced concrete work
The production of all types of work should be carried out in accordance with the PPR, the main provisions for the production of construction and installation work used in this project, and the requirements of the joint venture 70.13330.2012 "carrying and enclosing structures".
Concrete and a solution on the construction site is delivered to concrete mixers.
Concrete flow is carried out by concrete pump. Feeding formwork and reinforcement is provided by the truck.
Concrete mixtures should be laid in concrete structures with horizontal layers of the same thickness without breaks, with a sequential direction of laying in one direction in all layers.
When the concrete mixture is sealing, it is not allowed to support vibrators to fittings and mortgage products, heavy and other fastening elements. The depth of immersion of the deep vibrator in the concrete mixture should ensure its recess in the previously stacked layer by 5.00 - 10.00 cm. The step of rearrangement of the depths of the vibrators should not exceed the one-hour radius of their action, and the step of rearrangement of surface vibrators must provide overlap to 100.00 mm. The area of \u200b\u200bthe vibrator boundary of the already provincial plot.
The seal of the concrete mix depends on the duration of the vibration. The seal is considered sufficient if the sedimentation of the mixture is stopped, the separation of air bubbles is stopped, cement milk appears on the surface of the concrete structure.
In case of deformation or displacement of the formwork, concreting must be discontinued and the formwork is fixed before the establishment of concrete
In the initial period of hardening (up to 7 days), the concrete must be protected by a polymer film against atmospheric precipitation or moisture loss, subsequently, to maintain temperature and humidity regimen with the creation of conditions that ensure the increase in its strength.
During the rain, the concrete plot should be protected (by a polymer film, light mobile canopies, tarpaulin, etc.) from water to the concrete mix. Concrete, blurred rain should be removed.
The hardening concrete should be protected from mechanical damage.
Laying the next layer of the concrete mix is \u200b\u200ballowed before the selection of the concrete of the previous layer. The duration of the interruption between the laying of the adjacent layers of the concrete mix without the formation of the workshop is established by the construction laboratory. The top level of the laid concrete mix should be 50-70 mm below the top of the formwork shields
The quality of concrete stacked in the formwork is controlled by sampling the concrete mixture.
Control concrete samples must be selected in accordance with Table 4 GOST 10180-90 "Concretes. Methods for determining the strength of control samples. " The strength of the cubes should be carried out under conditions corresponding to the hardening conditions of concrete in the formwork.
Control cubes should be tested at 7 and 28 - daily age.
In the process of performing work, it is necessary to make data on concreting and control into special journals.
Concrete care measures, the order and timing of their conduct, control over their implementation and the timing of the structures of structures should be established by the PPR.
Reinforcement steel (rod, wire) and varietal hire, reinforcement and mortgage elements must comply with the project and requirements of the relevant standards. The dismemberment of spatial large-sized reinforcement products, as well as the replacement of the stipulated reinforcement steel should be coordinated with the customer and the design organization.
Transportation and storage of reinforcement steel should be performed according to GOST 7566-94 *.
The billet of the rods of dimensional length from the rod and wire fittings and the manufacture of unknown reinforcement products should be performed in accordance with the requirements of SNIP 3.09.01-85, and the manufacture of reinforcing frameworks from the rods with a diameter of more than 32.00 mm, rolling profiles - according to section 8 SP 70.13330- 2012.
The manufacture of spatial large-sized reinforcement products should be produced in assembly conductors.
The workpiece (cutting, welding, formation of anchor devices) and the installation of the reinforcement should be performed according to the project in accordance with SNiP 3.09.01-85.
Installation of reinforcement structures should be made mainly from large-sized blocks or unified grids of factory manufacture with securing the protective layer.
Installation on the reinforcement structures of pedestrian, transport or mounting devices should be carried out in accordance with the PPR, in coordination with the project organization.
Rods of rods should be made:
butt - peaks or crimping sleeves and screw couplings with the equalization of the junction;
cross-shaped - viscous annealed wire. It is allowed to use special connecting elements (plastic and wire locks).
Button and cross-shaped welded connections should be performed on the project in accordance with GOST 14098-91.
When the monolithic sections device in winter, the maintenance of concrete is performed by the electrical heating method. The electrical heating zone should be under the clock supervision of duty electricians.
The acceptance of the completed concrete and reinforced concrete structures or parts of structures should be issued in the prescribed manner as an act of examining hidden works or act on acceptance of responsible structures.
Installation of precast concrete structures
Installation of precast concrete structures must be carried out according to SP 70-13330-2012 "Bearing and enclosing structures"
Delivery of precast concrete blocks is carried out by the sidewall of g / n 20t.
A probe warehouse of reinforced concrete structures is located in the zone of the mounting crane.
Installation of structures is carried out using a tower crane.
Before lifting and moving prefabricated elements to the installation zone, it is necessary:
-Purry elements of shaking, snow, nondes, and metal parts - from rust;
- Name the axial risks and check the presence of elements based on elements;
- check the correctness and reliability of the lines.
Lifting, moving and lowering elements should be performed smoothly, without jerks, swinging and rotation. Prefabricated elements must be installed in a design position with appropriate reconciliation and design of design fixtures in nodes.
Release structures from the lines can only after their fixation.
Installation of the designs of each overlying floor (tier) of a residential building should be made after the design fixing of all mounting elements and achieve by concrete (solution) of deployed joints of the carrying structures of the strength specified in the PPR.
In cases where permanent ties do not ensure the stability of structures during their assembly, it is necessary to apply temporary mounting links. The design and number of connections, as well as the order of their installation and removal, must be specified in the PPR.
Designs should be configured. Works on the next tier should be started only after the design consolidation of all the designs of the underlying tier.
The limit deviations from the combination of landmarks during the installation of prefabricated elements, as well as the deviations of the completed installation structures from the project position should not exceed the values \u200b\u200bgiven in Table 12. SP 70.13330-2012.
Brickwork
Brick laying of walls is performed in accordance with the project and requirements of the joint venture 70.13330-2012.
Brick delivery is carried out onboard vehicles in pallets.
The supply of bricks and a solution to the place of production of work is made by a tower crane.
It is not allowed to weaken the brick masonry by holes, furrows, niches, assembly openings not provided by the project.
The thickness of the horizontal seams of masonry from bricks and stones of the correct shape should be 12 mm, vertical seams - 10 mm.
When performing a masonry bursting with a vertical finish in the layer seams, the mesh (reinforcement) from the longitudinal rods with a diameter of no more than 6 mm, from transverse rods - not more than 3 mm with a distance of up to 1.5 m in laying height, as well as in each overlap level .
The number of longitudinal rods of reinforcement is taken at the rate of one rod for every 12 cm wall thickness, but not less than two with a wall thickness 12 cm.
The construction of the stone designs of the subsequent floor is allowed only after laying the bearing structures of the elevated floors, the walls of the walls and the insoluction of the seams between the slabs of overlaps.
The limiting height of the construction of free-standing stone walls (without laying overlaps or coatings) should not exceed the values \u200b\u200bspecified in Table.28. SP 70.13330-2012. If you need to build free-standing walls of greater height, temporary mounts should be applied.
The height of the stone unarmed partitions, not liberated by overlaps or temporary mounts, should not exceed 1.5 m for partitions with a thickness of 9 cm, made of stones and bricks on a rib with a thickness of 88 mm, and 1.8 m - for partitions with a thickness of 12 cm, made from Brick.
All mortgage reinforced concrete elements (eaves, belts, balconies, etc.) must be provided by temporary fasteners to pinch them by the overlying masonry. The time for removal of temporary fasteners must be observed according to work drawings.
Given that the seismicity of this area is 7 points when laying from bricks, it is necessary to comply with the following requirements:
The laying of stone structures should be produced on the thickness of the structure in each row;
The masonry of the walls should be performed using a single-row (chain) dressing;
Horizontal, vertical, transverse and longitudinal laying seams should be filled with a solution completely with a trimming solution on the outer sides of the masonry;
Temporary (mounting) breaks in the erected masonry should be edged only with a slanting fine and places outside the wall reinforcement of the walls.
It is not allowed to use bricks with a large content of salts protruding on their surfaces.
The surface of the brick before laying must be cleaned from dust and dirt:
For masonry on ordinary solutions - water jet;

- incision for the building and cranes;
- technological schemes for basic work processes;
- drawings of temporary designs (if necessary);
- calendar construction schedule;
- annexes to the project - permissive documentation (SRO, Certification).
Development of the village
The development of the PIC is quite responsible work even for a small object. Despite the mandatory passage of the examination of project documentation (including POS), some companies do not provide due attention to this section. Competent development of the PIT is built at the following order:
- Buildingplane (construction master plan) - The most important part of the POS, decisive issues of the organization of the construction site and global security issues.
- Calculation of the duration of construction - (Section of the text part of the project) The task of the section is the correct calculation of the construction time of the object, and on this basis and such parameters, as the need for working personnel, temporary household facilities, construction machines and engineering.
- Other project sections - Full text part and calendar construction schedule (calendar construction plan).
STROYGENPLAN POS
The construction master plan in the composition of the PIT should solve the global issues of organizing the construction process, such as:
- fence of the construction site and design boundaries;
- the location and layout of household towns;
- location on the plan of buildings and neighboring structures;
- temporary roads, warehousing zones, wheel washers, gearbox, fire fights and electric cabinets, lighting masts, etc.;
- binding the main lifting mechanisms (cranes) and optimize their parameters;
- displays restrictions on the works of the cranes and the display of the main dangerous zones.
STROYGENPLAND POS - Sample Despite the mandatory development Project production of works by cranes (PPRK) In the future - the main issues of safe work must be solved on the stage of the POS - the joint work of several tower cranes (the ratio of heights and departures of arrows), the correct binding and selection of the parameters of the cranes (height, departure, carrying capacity). As part of the pos, it is not allowed to bypass these issues with references to the PPC.
Later, at the stage of working documentation or before starting construction work at the facility - on the basis of decisions of the staff is developed STROYGENPLAN STAGE "P" .
Calendar construction schedule (or calendar construction plan) include a graphical display of a total duration of work, the duration of the implementation of individual works ( preparatory work, underground part, overhead part, finishing, etc.), as well as combined challenges in labor resources - working personnel. Properly designed Calendar plan It gives an informative visual representation - at what points of time and for the production of which work is needed a certain number of workers, IER and other personnel.
Calendar construction schedule - sample 
The calendar schedule is obliged to consider all key points of construction. In the event of a resumption of the construction of an object after conservation, the stages of the works of previous years (before conservation) should be displayed on the calendar graph.
Examination and coordination of pos
All construction projects (pos) are examined by project documentation as part of the general project documentation. The choice of organization for the passage of the project documentation is carried out by the customer or the general designer of the object:
- for objects of state importance (architectural monuments, cultural heritage, etc.) - state examination project documentation;
- for other objects - non-state examination project documentation.
Who can develop pos
The development of the HAC is possible only by organizations that have access to the development of project documentation on capital construction facilities.
Although often design institutions have no own PIC engineers for high-quality project development, therefore they turn to third-party projectors (freelancers). You can read about the benefits and dangers of such development
The project of the construction of the PIC is a documentation where issues of the effective methods of organizing construction work in a particular situation on a specific facility are detailed. PIT is the main organizational document when erecting objects with industrial or non-productive purposes. The project contains measures for the use of modern technological and information funds, which make it possible to improve the quality of work, reduce the deadlines for the implementation of the entire project or its parts, reduce the cost of implementation.
The project is also developed when demolishing objects. When performing such operations, the PIT should ensure the safety of all operations, the correct disposal of waste and the absence of harm to the environment. Project organizations are engaged in the membership of the SRO with admission to certain types of work.
Composition of the construction organization
The composition of the organization's project and the content of its individual parts affects the complexity and specificity of objects, so the composition changes in accordance with the specific situation. The factors of influence include constructive solutions, the volume of planning works, the degree of uniqueness or use of typical solutions (as far as the object is unique), the need for the construction of auxiliary structures, the use of special devices, installations and devices, the specificity of the implementation of individual works. The composition of the POS influences how materials, equipment and various structures will be supplied to the construction site.
The construction project includes the following components:
- explanatory note;
- calendar plan for performing individual operations and all volume;
- general plans for the preparatory and main stages of construction;
- organizational and technological drawings, schemes and other graphic data;
- information about the volume of construction, installation operations, additional work;
- information on the necessary materials, pre-prepared structures, as well as used to solve the tasks of equipment;
- plan of need for devices, machines, construction equipment and transport with specific information on dates;
- information on the required frames for work.
Contents of the construction project
The most important parts of the project are the calendar plan for performing work and the master plan. If the remaining components may be present in a truncated form or not at all, then these are included in any pos, becoming its basis. All other statements and documents refer to the calendar schedule and the general plan, as for the rationale for their creation.
The calendar plan becomes a rational substantiation of the selected sequence. From the calendar plan of work it becomes clear why such an oddness is most effective, and in the organization of construction it is important. Clearly designate the timing of the execution of each stage of work.
The master plan describes the optimal accommodation on the entire construction site or its individual parts of the mechanisms for the lifting of goods, places for storing materials (some need special conditions), temporary roads for moving materials, mechanisms and various equipment, as well as other objects needed for construction . The master plan for the pos is different from a similar document for the project manufacturing a job with a more detailed answer to questions regarding ways to implement the tasks.
The explanatory note contains the details of the document, on the basis of which the project is started. This may be the decision of the developer, the implementation of the federal target program, a comprehensive program for the development of municipality and other documents. Here are the source data for the preparation of documentation, information on the functional purpose of the object, information about the need for utility services (gas, water, electricity, sewage). The correct project implementation allows not to spend unnecessary time to connect communications, not taken into account in the original plan. An explanatory note may contain other additional information, the volume of which depends on the complexity of the object being planned to build.
Source data for project development
The draft organization is carried out taking into account the data and documents that are present in the methodological recommendations. When creating a staff, the requirements of construction norms, a town-planning code, relevant federal laws apply. The provisions of the Decree of the Government of the Russian Federation dated 16.02.2008 N 87 are followed.
The development of the organizational project uses the initial data:
- planning scheme and organization of land;
- solutions for architecture and planning of cities;
- constructive decisions;
- project documentation for projected external networks of electricity, communication and other communications;
- information about engineering and communication networks located in the execution zone and sources of water supply platform, electrical energy and necessary types of communication;
- the statement of the number of major construction, installation and additional types of work;
- a project of execution of operations for dismantling facilities (if construction is planned on the site of an existing object or simply demolition and dismantling of a production or non-production building).
The source data is needed to fill the relevant sections. Constructive solutions become the basis of the statements about the needs in certain structures for installation. To describe technological and organizational schemes, a significant amount of information is required, in the process of making the most efficient solutions, the initial data of several types are used in the process. Demolition work under the condition of new construction is not required, so the set of source data also does not imply the presence of all the items described without exception.
The basis for the development of the construction project project is the task of the customer with the technical conditions of implementation, which also applies to the number of source data.
The main objectives of the preparation of pos
The organization's draft is considered part of the construction of an object, in which the solution of all possible organizational issues arising during work is considered as much as possible. PRA concerns the entire volume of construction from the very beginning to commissioning.
The purpose of creating a project is to pass an object within the time limit. Effective organizational solutions make it possible to properly spend the allocated time, eliminate the probability of downtime due to problems with the supply of materials, a summary of technology, the impossibility of establishing in the event of the need for certain mechanisms and structures. The use of modern technologies takes into account the use of modern technologies, allowing to reduce the construction time and achieve quality required by standards and rules.
The project allows you to solve the following tasks:
- the use of optimal methods of the organization to carry out construction in the minimum time;
development of project power to the date established by the contract; - the use of modern technologies to comply with the requirements of construction standards and rules, ensure high quality;
- timely supply of structures, materials, products on the object or its individual components (floors of a high-rise building, for example);
- application of vehicles for quick installation of structures;
- installation of technological equipment by large blocks, if there is an opportunity to reduce the duration of operations;
- compliance with the security requirements and environmental protection in order not to exceed the standards from the technical regulation.
The project creation is maintained taking into account the peculiarities of natural and climatic conditions in the construction area. The implementation of many tasks at certain times of the year is simplified or complicated, the correct approach allows you to choose the optimal time to solve the tasks. Sometimes the possibility of delivering equipment and materials is influenced by seasonality, also play the role of territorial features. For the northern climatic zone, there are special security requirements related to increased risks. Also, special conditions are characterized by work in mountainous areas.
Requirements for design and content
The project includes textual and graphic components. Explanatory note contains only text, graphics can be applied in other sections as needed. In the graphic part there are schemes, drawings, plans and other documents in the form of graphics. The text component contains explanations, descriptions, information about the object, the reasons for making specific solutions, calculations, references to the technical documents and standards used during the design. There may also be diagrams, drawings, graphics and data in tabular form.
Conducting work in the conditions of cramped urban development requires a description of the causes of constraints and methods of construction in the designated situation. The safe performance of construction work in the danger zone requires the right organizational solutions in the form of limiting the zone of the movement of cranes, the arrangement of shelters and other structures to protect staff and other people, using screens.
The following data includes the construction section of the construction in the constrained building:
- conditions of installation and specificity of work on the crane at a small distance from the pit;
- the need to overlap streets at a certain time, restrictions on the movement of cars, changes in public transport routes;
- organization of construction work near power lines to protect against damage to communication networks.
An important component of the organization of construction work is to satisfy the need for personnel and resources. This is clearly described by the number of necessary specialists and their employment period, a list of necessary materials and structures with optimal delivery data. The construction plan is a guarantee of the implementation of construction operations on time with appropriate quality.
