Depending on the complexity of the object, the conditions of the construction works and socio-economic importance points can be added, expanded, have a more detailed structure.

In the POS, such aspects of the construction and installation work as logistics must be noted;

• safety and labor protection;
• natural and climatic conditions;
• technical equipment;
• compliance with environmental protection standards;
• providing the object with communications and much more.

Only a deep knowledge of the specifics of construction, repair and installation work, accompanying documents and standards, can ensure the preparation of a competent detailed Construction Organization Project. And already on this basis, other documents, permits and permits will be formed. So, in particular, the Project for the Production of Works (PPR) is built on the basis of the POS and contains, in fact, a step-by-step plan for carrying out work on each section of the facility.
Thus, the Construction Organization Project is a mandatory document, both for the contractor and for the customer, and for organizations providing the material and technical support of the construction site, which needs to be agreed upon by the parties and finally approved by the state examination.

We carry out the development of POS for construction work and the laying of engineering communications:

• explanatory note
• construction plan for the preparatory period

• explanatory note
• work schedule
• construction plan for the main period of work

14 years of successful work

More than 140 PIC projects in 9 cities across Russia

PIC development for industrial facilities any complexity

Coordination of PIC projects

Accompanying the PIC in the examination and Glavgosexpertiza

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 in the package project documentation includes a construction project. The significance of the PIC is emphasized by the fact that this document is subject to state examination, based on the decision of which a building permit is issued within the time limits fixed in the PIC.

Unlike the project for the production of works, developed for individual construction objects, the project for the organization of work covers the entire complex of buildings and structures at construction site. On the basis of the master plan, several WEPs are drawn up, which consider in detail the technological process, the rational organization of construction and the expenditure of material, technical and labor resources for the construction of a particular object. Construction organization projects are developed as for the whole residential neighborhoods with a diverse infrastructure, large industrial complexes, and for individual buildings and structures. POS is also necessary if it is planned to enlarge or reconstruct objects. The construction organization project is a mandatory document for the customer, contractors construction organizations, and organizations responsible for financing and logistics of construction.

Features of POS development

The construction organization project provides organizational and technical preparation for construction and substantiates the timing and sequence of commissioning of facilities.

Based on engineering calculations (when reconstructing facilities - based on materials technical survey) and the necessary project documentation in the PIC, the total volumes are calculated capital investments and construction and installation works, indicating the time of execution, the need for the necessary workforce, taking into account their qualifications and the need for material and technical resources. The POS must contain information about:

• solving the problems of organization of transport, water supply, sewerage, energy supply, communications;

• schemes for warehousing and slinging of goods, etc.;

The composition, as well as the content of the POS, may vary depending on the characteristics of a particular object, the specifics of the conditions for the work or delivery of materials, as well as other aspects of construction. When erecting simple objects, an abbreviated version of the PPR can be used.

Objects requiring a special approach to the implementation of construction work are listed below:

• residential buildings;
• buildings that will be used to provide household services population;
• main road or railways, gas and oil pipelines, power lines and communications;
• water management or hydrotechnical facilities;
• enterprises specializing in the extraction of minerals, other objects.

The peculiarity of the conditions under which construction is carried out also plays a significant role during the development of the PIC. Features in the preparation of documentation are defined for objects that are being built:

• in winter;
• on soils with special properties;
• in mountainous areas;
• in special natural conditions.

The area of ​​construction, its features, the complexity of the work performed are the parameters that have the main impact on the content of the PPR and POS.
The complexity of the process of developing the design of a construction organization depends on the specific object, its scale and specifics. POSSTROY specialists offer their services to create projects of any complexity, from a small cottage to a large irrigation and drainage or industrial complex. High qualifications, rich work experience and prompt problem solving are the key to successful cooperation with POCSTROY.

The text part of the POS should contain:

• a list of measures to organize monitoring of the condition of buildings and structures located in close proximity to the facility under construction, earthworks, construction, installation and other work on which may affect the technical condition and reliability of such buildings and structures;

The graphic part of the POS should contain:

Thus, a large number of subject-specific PPRs of the most diverse kind are based on information taken from the PIC. It is prohibited by law to start construction and installation work without having a POS that has passed the examination in the prescribed manner. Project documentation will be needed not only by the investor, the customer of construction, but also by contracting construction organizations.

Depending on the complexity of the construction, the development of the POS is carried out in one or two stages - the "Project" stage (P) and the "Detailed documentation" stage (P).

Stroygenplan
Stroygenplan is an essential part of the PIC project. In it you can see how functionally and rationally the zones for storing materials and raw materials are organized, household, administrative, sanitary facilities, temporary roads are located. Also, the construction site plan shows all hazardous areas and methods for their elimination, shows the location and operation of the main mechanisms, their interaction and joint work.

Calendar plan
A calendar plan or schedule is a document that clearly defines the duration, sequence and combination of work performance, indicating the financial costs of construction by stages, for PIC it is generalized, for PPR it is specified. This document, undoubtedly, is one of the defining objects in the organization of competent and timely financing of objects. Also, the schedule shows the dependence of construction on local climatic conditions, when the facility is in difficult conditions.

Explanatory note
An explanatory note is an equally important element of construction organization projects. From the explanatory note, you can get a detailed idea of ​​all the features of the conditions for the upcoming construction, as well as its sequence, methods and technology for the production of construction and installation works, quality control and other processes necessary for construction. Also, in the explanatory note, all calculations are made necessary to determine the needs of construction in providing labor resources, engineering support, etc.

Regulatory Framework for PIC Development

Construction refers to the area of ​​activity in which the requirements for documentation are especially strict, they are based on numerous norms, joint ventures, SNiPs and rules. One of the main documents, the obligatory presence of which is approved in SP 48.13330.2011, is the PPR - the project for the production of works.

federal law Urban Planning Code The Russian Federation regulates the need to develop a PIC. According to him, the start of work in the field of capital construction is unacceptable without the availability of project documentation, to which the construction organization project belongs. The development of the PIC section is carried out in accordance with SP48.13330.2011 and c Decree of the Government of the Russian Federation No. 87 of February 16, 2008.

For residential buildings, the sequence of erection of the building itself, external networks is presented engineering support, landscaping. The following is a description of all the listed works.

The technological sequence of work established by the organizational and technological schemes is the source material for the development of the schedule.

An example of a description of the work provided for in the project

(this example is not universal. The set of works is adjusted in accordance with the adopted technical solutions):

Excavation

Earthworks must be carried out in accordance with the rules
SP 45.13330-2010 "Earth structures, foundations and foundations".

During the construction of a residential building excavation begin with the removal of the fertile soil layer in a non-frozen state with its movement to a temporary dump outside the removal zone. Cutting off the fertile soil layer and moving the fertile soil layer is carried out by transverse and longitudinal passages of the bulldozer.

The dump should be located at a distance of no closer than 0.5 m from the edge of the trench being developed to prevent it from shedding. When removing, moving and storing the fertile soil layer, it is not allowed to mix it with mineral soil by rocks, contamination with liquids or materials, erosion and blowing, as well as its use for backfilling.

When developing a trench, the excavator must be outside the prism of soil collapse (slope) at a distance indicated in Table 1.

Table (table number) –– The smallest distance from the base of the slope to the nearest machine supports

Soil (not bulk)	With excavation depth, m
	1,00	2,00	3,00	4,00
Table continuation
Sand and gravel	1,50	3,00	4,00	5,00
sandy loam	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
Loess dry	1,00	2,00	2,50	3,00

When excavating a trench with an excavator, the soil must be ejected to a distance of at least 0.50 m from the edge of the trench (pit) in dry and cohesive soils and at least 1.00 m in sandy and moist soils.

A trench with vertical walls without fastening is developed by a single-bucket excavator in soils of natural moisture with an undisturbed structure in the absence of groundwater to a depth of not more than:

In bulk sandy and gravelly soils 1.00 m;

In sandy loam 1.25 m;

In loams and clays 1.50 m;

In especially dense non-rocky soils 2.00 m.

When digging trenches and pits of greater depth, it is necessary to arrange slopes of various levels depending on the composition of the soil at a groundwater level below the excavation depth according to Table 2.

Table (table number) - Permissible trench slope slope

soils	Trench depth, m
	Up to 1.50		1,50-3,00		3,00-5,00
	slope angle, degree	bias	slope angle, degree	bias	slope angle, degree	bias
Bulk	56	1:0,67	45	1:1,00	38	1:1,25
Sand and gravel	63	1:0,50	45	1:1,00	45	1:1,00
sandy loam	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 a trench with a single-bucket excavator should be carried out with the elimination of scallops at the bottom in the process of digging, which is achieved by dragging the bucket along the bottom of the trench after the development of the face.

In case of occurrence of groundwater, it is necessary to drain the incoming water from the sump (pit), followed by pumping out with a pump (piston, diaphragm or centrifugal, depending on the pressure of the incoming water) to the surface, where water is diverted from the pit through drainage grooves or trays.

The soil in the pit is selected not reaching the design mark of -10 cm.

The soil for backfilling the sinuses of the trenches and the pit is moved by a bulldozer 9 or dump trucks from the reserve.

Backfilling of trenches and sinuses of the excavation should be carried out with mineral soil without construction debris, without inclusions of large fragments (more than 50 mm in diameter) of hard rocks (crushed stone, gravel, frozen clods) with layer-by-layer compaction with pneumatic rammers and platform rammers.

Monolithic reinforced concrete works

The production of all types of work must be carried out in accordance with the PPR, the main provisions for the production of construction and installation works used in this project, and the requirements of SP 70.13330.2012 "Bearing and enclosing structures".

Concrete and mortar are delivered to the construction site by truck mixers.

The supply of concrete is carried out by a concrete pump. The supply of formwork and reinforcement is provided by a truck crane.

Concrete mixtures should be laid in concreted structures in horizontal layers of the same thickness without gaps, with consistent direction of laying in one direction in all layers.

When compacting the concrete mixture, it is not allowed to rest the vibrators on the reinforcement and embedded products, strands and other elements of the formwork fastening. The depth of immersion of the deep vibrator in the concrete mixture should ensure its deepening into the previously laid layer by 5.00 - 10.00 cm. platform of the vibrator of the border of the already vibrated area.

The compaction of the concrete mixture depends on the duration of the vibration. Compaction is considered sufficient if the mixture stops settling, air bubbles are released, cement milk appears on the surface of the concreted structure.

In case of deformation or displacement of the formwork, concreting must be stopped and the formwork corrected before the concrete starts to set.

In the initial period of hardening (up to 7 days), concrete must be protected with a polymer film from atmospheric precipitation or moisture loss, and subsequently, temperature and humidity conditions must be maintained with the creation of conditions that ensure an increase in its strength.

During rain, the area to be concreted must be protected (with a polymer film, lightweight movable canopies, tarpaulins, etc.) from water ingress into the concrete mixture. Concrete washed out by rain should be removed.

Hardening concrete should be protected from mechanical damage.

Laying of the next layer of concrete mixture is allowed before the beginning of setting of the concrete of the previous layer. The duration of the break between the laying of adjacent layers of concrete mix without the formation of a working seam is established by the construction laboratory. The top level of the laid concrete mixture should be 50-70 mm below the top of the formwork panels

The quality of the concrete placed in the formwork is controlled by sampling the concrete mixture.

Control concrete samples should be taken in accordance with Table 4 of GOST 10180-90 “Concrete. Methods for determining the strength of control samples. The curing of the cubes must be carried out under conditions corresponding to the conditions of concrete hardening in the formwork.

Control cubes should be tested at 7 and 28 days of age.

In the process of performing work, it is necessary to enter data on concreting and control in special logs.

Measures for the care of concrete, the procedure and timing of their implementation, control over their implementation and the timing of the stripping of structures should be established by the PPR.

Reinforcing steel (bar, wire) and rolled sections, reinforcing products and embedded elements must comply with the project and the requirements of the relevant standards. The division of spatial large-sized reinforcing products, as well as the replacement of the reinforcing steel provided for by the project, must be agreed with the customer and the design organization.

Transportation and storage of reinforcing steel should be carried out in accordance with GOST 7566-94*.

Procurement of bars to measure length from bar and wire reinforcement and the manufacture of non-stressed reinforcing products should be carried out in accordance with the requirements of SNiP 3.09.01-85, and the manufacture of load-bearing reinforcing cages from bars with a diameter of more than 32.00 mm, rolled profiles - in accordance with section 8 of SP 70.13330- 2012.

The manufacture of spatial large-sized reinforcing products should be carried out in assembly jigs.

Preparation (cutting, welding, formation of anchor devices) and installation of reinforcement should be carried out according to the project in accordance with SNiP 3.09.01-85.

Installation of reinforcing structures should be carried out mainly from large-sized blocks or unified prefabricated meshes, ensuring that the protective layer is fixed.

Installation of pedestrian, transport or mounting devices on reinforcing structures should be carried out in accordance with the PPR, in agreement with the design organization.

Non-welding connections of rods should be made:

butt - overlap or crimp sleeves and screw couplings to ensure the equal strength of the joint;

cruciform - viscous annealed wire. It is allowed to use special connecting elements (plastic and wire clamps).

Butt and cruciform welded joints should be made according to the project in accordance with GOST 14098-91.

When constructing monolithic sections in winter, the curing of concrete is carried out by the method of electrical heating. The electric heating zone must be under round-the-clock supervision of electricians on duty.

Acceptance of finished concrete and reinforced concrete structures or parts of structures should be drawn up in accordance with the established procedure with an act of examination of hidden works or an act for the acceptance of critical structures.

Installation of precast concrete structures

Installation of prefabricated reinforced concrete structures must be carried out in accordance with SP 70-13330-2012 "Bearing and enclosing structures"

Delivery of prefabricated reinforced concrete blocks is carried out by a side carrier with a capacity of 20 tons.

The on-site warehouse of reinforced concrete structures is located in the area of ​​operation of the assembly crane.

Installation of structures is carried out using a tower crane.

Before lifting and moving prefabricated elements to the installation area, it is necessary:

- clean the elements of dirt, snow, ice, and metal parts - from rust;

– apply axial risks and check the presence of marks for the places where the elements are supported;

– check the correctness and reliability of the slinging.

Lifting, moving and lowering the elements should be carried out smoothly, without jerks, swinging and rotation. Prefabricated elements must be installed in the design position with appropriate alignment and design fastenings in the nodes.

It is possible to release structures from slinging only after they are fixed.

The installation of the structures of each overlying floor (tier) of a residential building should be carried out after the design fixing of all installation elements and the concrete (mortar) of the monolithic joints of the supporting structures of the strength specified in the PPR.

In cases where permanent connections do not ensure the stability of structures during their assembly, it is necessary to use temporary mounting connections. The design and number of connections, as well as the procedure for their installation and removal, should be indicated in the PPR.

Structures should be installed in layers. Work on the next tier should be started only after the design fixing of all structures of the underlying tier.

Limit deviations from the alignment of landmarks when installing prefabricated elements, as well as deviations of completed mounting structures from the design position, should not exceed the values ​​\u200b\u200bgiven in Table 12. SP 70.13330-2012.

Brickwork

Brickwork of the walls is carried out in accordance with the project and the requirements of SP 70.13330-2012.

Delivery of bricks is carried out by onboard trucks in pallets.

The supply of bricks and mortar to the place of work is carried out by a tower crane.

No weakening allowed brickwork holes, grooves, niches, mounting openings not provided for by the project.

The thickness of the horizontal joints of masonry of bricks and stones of the correct form should be 12 mm, vertical joints - 10 mm.

When performing a break in the masonry with a vertical chisel, a mesh (reinforcement) of longitudinal rods with a diameter of not more than 6 mm should be laid in the seams of the masonry chisel, of transverse rods - not more than 3 mm with a distance of up to 1.5 m along the height of the masonry, as well as at the level of each overlap .

The number of longitudinal reinforcement bars is taken at the rate of one bar for every 12 cm of wall thickness, but not less than two for a wall thickness of 12 cm.

erection stone structures the next floor is allowed only after laying the supporting structures of the floors of the erected floor, anchoring the walls and embedding the seams between the floor slabs.

The maximum height of the construction of free-standing stone walls (without laying ceilings or coatings) should not exceed the values ​​\u200b\u200bspecified in Table 28. SP 70.13330-2012. If it is necessary to erect free-standing walls of greater height, temporary fastenings should be used.

The height of non-reinforced stone partitions not fastened with ceilings or temporary fastenings should not exceed 1.5 m for partitions 9 cm thick, made of stones and bricks on an edge 88 mm thick, and 1.8 m - for partitions 12 cm thick, made of bricks.

All embedded reinforced concrete prefabricated elements (cornices, corbels, balconies, etc.) must be provided with temporary fasteners until they are pinched by the overlying masonry. The term for removing temporary fasteners must be observed in accordance with the working drawings.

Considering that the seismicity of this area is 7 points, when laying bricks, it is necessary to comply with the following requirements:

Masonry of stone structures should be carried out for the entire thickness of the structure in each row;

Wall laying should be carried out using a single-row (chain) dressing;

Horizontal, vertical, transverse and longitudinal masonry joints should be filled with mortar completely with trimming the mortar on the outer sides of the masonry;

Temporary (mounting) gaps in the masonry being erected should only be terminated with an inclined chimney and located outside the places of structural reinforcement of the walls.

It is not allowed to use bricks with a high content of salts protruding on their surfaces.

The surface of the brick before laying must be cleaned of dust and dirt:

For laying on ordinary solutions - with a jet of water;

For laying on polymer cement mortars - using brushes or compressed air.

At negative outside temperatures, brickwork should be made on solutions with antifreeze additives. In this case, the following requirements must be observed:

Prior to commencement of masonry work, it is necessary to determine optimal ratio between the value of pre-moistening of the wall material and the water content of the mortar mixture;

The POS construction organization project is a documentation that discusses in detail the issues of effective methods of organizing construction work in a specific situation at a specific facility. The POS is the main organizational document in the construction of facilities that have an industrial or non-industrial purpose. The project contains measures to use modern technological and information tools to improve the quality of work, reduce the time for the implementation of the entire project or its parts, and reduce the cost of implementation.

The project is also developed during the demolition of objects. When performing such operations, the POS must ensure the safety of all operations, the correct disposal of waste and the absence of harm to the environment. are engaged in design organizations that have SRO membership with access to certain types of work.

Structure of the construction organization project

The composition of the organization's project and the content of its individual parts are affected by the complexity and specificity of objects, so the composition changes in accordance with the specific situation. Influencing factors include constructive solutions, the scope of planning work, the degree of uniqueness or the use of standard solutions (how unique the object is), the need for the construction of auxiliary structures, the use of special devices, installations and devices, the specifics of implementation individual works. The composition of the POS is affected by how exactly materials, equipment and various structures will be supplied to the construction site.

The construction organization project includes the following components:

• explanatory note;
• execution schedule individual operations and the whole volume
• master plans for the preparatory and main stages of construction;
• organizational and technological drawings, diagrams and other graphic data;
• information on the volume of construction, installation operations, additional work;
• information about the necessary materials, pre-prepared structures, as well as the equipment used to solve the tasks;
• a plan for the need for devices, machines, construction equipment and transport with specific information on dates;
• information about the required personnel for the performance of work.

• a project for the execution of operations for the dismantling of facilities (if it is planned to build on the site of an existing facility or simply demolish and dismantle an industrial or non-industrial building).

The initial data is needed to fill in the relevant sections. Structural solutions become the basis for a statement of needs for certain installation structures. To describe technological and organizational schemes, a significant amount of information is required; in order to make the most effective decisions, several types of initial data are used at once in the process. Demolition works are not required for new construction, so the initial data set does not assume that all the items described are present without exception.

The basis for the development of a construction organization project is the task of the customer with specifications execution, which also applies to the number of initial data.

The main objectives of compiling a PIC

The project of the organization is considered a part of the construction of the facility, in which the solution of all possible organizational issues arising during the execution of work. The PIC covers the entire scope of construction from the very beginning to commissioning.

The purpose of creating a project is to deliver an object to deadlines. Effective organizational solutions make it possible to properly spend the allotted time, eliminate the likelihood of downtime due to problems with the supply of materials, supply of equipment, the inability to install certain mechanisms and structures if necessary. The PIC takes into account the use modern technologies, allowing to reduce the construction time and achieve the quality required by standards and regulations.

The project allows to solve the following tasks:

• application of optimal organization methods for construction in the shortest possible time;
  development of design capacity by the date established by the contract;
• the use of modern technologies to meet the requirements of building codes and regulations, to ensure high quality;
• timely delivery of structures, materials, products to the facility or its individual components (floors of a high-rise building, for example);
• the use of vehicles for quick installation of structures;
• installation of technological equipment in large blocks, if there is such an opportunity to reduce the duration of operations;
• compliance with safety and environmental protection requirements, so as not to exceed the standards from the Technical Regulations.

The creation of the project is carried out taking into account the peculiarities of natural and climatic conditions in the area of ​​construction. The implementation of many tasks at certain times of the year is simplified or complicated, the right approach allows you to choose the optimal time for solving the tasks. Sometimes seasonality affects the possibility of delivering equipment and materials, and territorial features also play a role. For the Northern climatic zone, there are special safety requirements associated with increased risks. Also, special conditions are characterized by work in mountainous areas.

Requirements for the design and content of the POS

The project includes text and graphics components. The explanatory note contains only text; graphics can be used in other sections as needed. The graphic part contains 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 decisions, calculations, links to technical documents and standards used during the design. Diagrams, drawings, graphs and data in tabular form can also be located here.

Carrying out work in conditions of cramped urban development requires a description of the causes of crampedness and methods for performing construction in the indicated situation. The safe execution of construction work in a hazardous area requires the right organizational decisions in the form of limiting the zone of movement of cranes, the arrangement of shelters and other structures to protect personnel and other people, the use of screens.

The following data is included in the section on construction in cramped buildings:

• installation conditions and specifics of work on the crane at a short distance from the pits;
• the need to block streets at certain times, restrictions on the movement of cars, changes in public transport routes;
• organization of construction works near power lines to protect communication networks from damage.

An important component of the organization of construction work is to meet the need for personnel and resources. For this, the number of necessary specialists and the period of their employment, a list of necessary materials and structures with optimal delivery data are clearly described. The construction organization plan is a guarantee that construction operations will be completed on time with the proper quality.

Construction work implies the presence of legal documentation at any stage of the process. The presence of a properly drawn up action plan makes it possible to avoid negative aspects after the commissioning of the facility under construction.

For these purposes, there is a special document - a construction organization project (POS). POS is usually developed by a general contracting design organization. If necessary, for this purpose, the general designer may involve, as subcontractors, organizations specialized in the development of POS or individual complex installation work. POS must be provided to companies that directly finance construction work, provide the entire base of materials; for organizations that carry out contracts, as well as for customer enterprises. The presence of a POS regulates the subsequent development of a project for the production of works (PPR).

PIC development process

To develop a project, certain basic data are required:

1. Data about engineering surveys. They are necessary in a situation where restoration work is being carried out at the facility, or work on the reconstruction of the facility (technical survey indicators are required).
2. Task for the design process. This documentation contains initial data that are directly related to the construction process. The presence of these indicators makes it possible to make a queue for the launch of a particular queue.

• budget documentation;
• permits, which gives a visualization of the distribution of the object's input into queues;
• documentation that describes the briefing and engineering explanation for the number of storeys, layout, scope of work;
• a summary plan-paper characterizes the features of engineering communications, with mandatory approval;
• a vertical plan of the construction site, which includes a cartogram of the masses of the earth layer;
• a phased plan for the protection of the construction site from the effects of weather conditions according to the geographical features of the region;
• the customer company provides a document that describes the features of the supply of water and electricity to the construction site;
• regulatory documentation, acts that establish the final deadlines for the work;
• acts on deliveries to the territory of the logistics facility by the contractor company;
• documents on the work plan for the removal of garbage from the site, its storage or processing location. It also provides for an agreement on the transportation of soil, the place of its dumping;
• in a situation where we are talking on the installation work of objects of complex structures, their coordination is required;
• agreements are required when working with companies of foreign origin;
• documentation during work on construction sites;
• careful selection and study of information about general contractor, if the information does not belong to the privacy column.

The company "PPR EXPERT" develops a complete set of all the necessary volumes of POS documentation. If the construction work is divided into stages, then in this case the PIC has an individual character for each. The construction organization project developed by the company contains:

1. Construction schedule. It makes it possible to set deadlines for the initial stages and completion of work.
2. The construction master plan is one of the main documents of the organization of construction.
3. Organizational and technological schemes of work on the site.
4. Acts and statements that describe the need and the number of involved vehicles.
5. Schedule of demand for basic construction machines; schedule of demand for construction workers by main categories.
6. Explanatory note.

When it comes to the reconstruction of functioning enterprises, buildings, facilities, in addition to the above list, the company carries out clarification work, which is as follows:

• the state of an existing or inactive building is accurately established;
• actions are differentiated according to the stop of the relevant processes that interfere with the work;
• the queue of works regarding installation and installation is established;
• Markings are applied to the stoygenplan, which carry information regarding the state of objects near the immediate work area. As well as designations for existing, dismantling, installation, reconstruction and construction works;
• in explanatory notes specialists of the company "PPR EXPERT" bring information and clarity, according to the interaction of all involved persons according to the construction or installation plan. The data in the note have a fairly detailed and extensive information composition. It contains data on conditions, transport possibilities, material base enterprises. In the case of installation or dismantling work, data is entered in the note on the guaranteed safety and fire safety of objects located in the immediate vicinity.

The company has highly qualified specialists with certificates of the highest degree. Capable with minimal time and financial costs design a POS of any degree of complexity. Positive reviews customers only confirm high level reliability.

Construction organization project (POS): initial data, composition and development procedure.

The first stage in the organization of construction work is the development of project documentation for the facility, which should take into account modern methods and materials used in construction.

The development of a PIC begins with the preparation of a feasibility study (FS). At this stage, the need for resources and the amount of capital investments are determined.

The design of large construction projects is carried out in two stages. At the stage of the technical project, the development special section POS. For simpler, one-stage projects, the PIC is done in an abbreviated format. The main requirements for the construction organization project and its composition are regulated by the building codes of the Russian Federation.

The development of a POS must be carried out based on the following requirements:

• reduction of cost and construction time;
• improving the quality of work;
• maximization of labor productivity.

The construction organization project is aimed at solving the following tasks:

• determination of the optimal duration of construction;
• drawing up a calendar plan or a network schedule for the production of work;
• financing schedule, depending on the total period of work (by years, quarters, months);
• compiling a list of necessary resources, namely materials, equipment, labor, construction vehicles, and a schedule for their use;
• identification of sources of obtaining building materials;
• development of transport schemes;
• development of a construction plan with a justification of the needs for existing production resources;
• development of technological schemes and maps by type of work;
• occupational health and safety for all types of construction work.

The procedure for developing a construction organization project

Before developing a PIC, an analysis is made of data that characterize natural conditions in the construction area, as well as such parameters as the size of the construction object, its purpose, scope of work, materials used.

Before developing a construction organization project, the following additional surveys are carried out:

• availability of local building resources: materials and products, structures, factories and workshops;
• transport infrastructure: road network, logistics organizations, etc.
• local labor resources and the possibility of their involvement in construction work;
• the possibility of obtaining electricity and fuel in the construction area;
• possible sources of water supply.

Based on the above conditions, a construction organization project is being developed. The PIC justifies the distribution of material and human resources, and is also the source for the development of the PPR for certain types works.

One of the most important tasks that the TFP solves is the optimization of the duration of construction (time / cost). In case of implementation of large construction projects, several PIC options can be developed for comparison and selection of the optimal one.

The development of a construction organization project is carried out for a full construction cycle. When developing by construction phases, the design for each phase must take into account the full scope of the planned work.

Depending on the complexity and detail of the POS, there are three categories of construction projects:

This category includes the following types of objects:

• atypical building objects with complex, individual design solutions;
• objects with difficult conditions for the supply of basic equipment for individual technical. solutions and individual orders;
• involving a large number subcontractors.

Objects of medium complexity, which are built according to individual projects. A limited number of subcontractors are involved in the work.

Small objects, for the construction of which one-stage projects are used, and up to 3 subcontractors are involved in the work.

Structure of the construction organization project

1. Construction schedule

2. The nature of the construction and the conditions for its implementation

2.1. This project documentation provides for the construction of a multi-level residential building with built-in premises.

The facility being designed is located in the Pushkin administrative district of St. Petersburg, Shushary village, Xxxxxxxxxx street, d.xx, lit.X, NXX residential building.

The plot planned for development is located in the area of ​​​​promising development on the intra-quarter territory and belongs to LLC " Construction company"Hhhhhhhhhh."

From the north, south and west, the construction site is limited by agricultural land, from the east the site is limited by the existing construction site. The site is free from buildings and green spaces and is characterized by a flat relief.

On the territory of the building plot there are overhead power lines, which will be cabled before the start of construction.

The construction area belongs to the I territorial zone of the II climatic region.

The location of the facility within the city makes it possible to use city roads and utilities for the construction period.

Works on the construction of the facility are planned to be carried out by the general contractor with the involvement of specialized subcontractors.

The contractor is determined by the customer.

The construction organization must have the necessary production facilities, a sufficient number of machines and mechanisms, as well as qualified personnel.

2.2. Building materials, products and structures will be delivered to the site centrally by trucks from industrial enterprises and enterprises of the construction industry of St. Petersburg and the Leningrad region according to the following transport scheme:

- Ready-mixed concrete - concrete plant LLC "SK" Khxxxxxxxxxxxx.

- crushed stone - from the warehouse of OJSC "Lentekhstrom" by road transport at a distance of up to 10 km.

- sand - from the warehouse of OOO "Stroytrans" by road at a distance of up to 20 km.

Construction waste, under an agreement with a special organization, is transported outside the construction site by road to the city dump at a distance of up to 20 km.

(Volkhonskoye Highway 118, KPO test site)

2.3. Brief climatological reference.

The city of St. Petersburg is located on the coast of the Gulf of Finland of the Baltic Sea at the mouth of the Neva River and on the islands of its delta. On the lowland adjacent to the Neva and its continuation along the bay are the nearest suburbs.

The territory of the city and its environs is under the influence of sea (Atlantic) and continental air masses of temperate latitudes, frequent occurrences of arctic air and active cyclonic activity. As a result of the interaction of all climate-forming factors, a climate close to maritime is formed, with moderately warm, humid summers and rather long, moderately cold winters. The average annual air temperature is 4.2 °C, and the period with a long temperature is 222 days. On average, for a year in St. Petersburg there are clear and cloudless days - 31, cloudy - 172, foggy - 57, semi-clear, with variable cloudiness - 105. Positive air temperature is established from April 3 to November 11, during this time (222 days) on average, there are 126 rainy days (excluding intermittent rains). In the cold period (143) days, on average, 61 days with repeated precipitation (snow, hail, hoarfrost). In total, there is relatively little precipitation: 650-700 mm per year.

2.4. Engineering-geological and hydrogeological conditions of the construction site are characterized by a complex lithological structure - multi-layered vertical stratification of soils, deep occurrence of dense (reference) soil layers. The soils are presented as follows:

- from the surface - bulk soils: plastic, brown sandy loam, mixed with sands of different sizes, wet, with gravel and pebbles, with construction waste (broken brick, glass). The thickness is 0.40-1.70 m;

- Lacustrine-glacial deposits - loams are light, silty, hard-plastic, brown, with interlayers of silty sands, moist and saturated with water, with rare gravel and pebbles, ferruginous. The thickness is 0.80-3.60 m;

- Glacial deposits - silty plastic sandy, gray, with interlayers of silty sands saturated with water, with gravel and pebbles up to 5-10%. The thickness is 0.80-1.50 m;

- light and heavy silty loams, hard-plastic, gray, with interlayers of silty sands saturated with water, with gravel and pebbles up to 5%. The thickness is 5.30-8.70 m;

- heavy silty semi-solid loams, bluish-gray, with interlayers of silty sands saturated with water, with gravel and pebbles up to 5%. The thickness is 1.50-3.50 m;

- Cambrian deposits - clays, heavy and light, silty, hard, dislocated, blue, with thin layers of silty sands, with fragments of sandstone. The thickness is 4.00-8.40 m;

- clays, heavy and light, silty, hard, blue, with thin layers of sandstone. The thickness is 1.60-7.00 m.

The normative depth of seasonal freezing for bulk soils is 1.39 m, for lacustrine-glacial loams of refractory, ferruginous, it is 1.15 m.

According to the degree of frost heaving, bulk soils belong to medium heaving soils, silty dense sands belong to strongly heaving soils, coarse, medium-density and dense sands and medium-sized, dense sands belong to practically non-heaving soils.

The hydrogeological conditions of the work site at the drilling depth are characterized by the presence of groundwater confined to modern bulk soils, to Quaternary deposits: to lenses and interlayers of sand in lacustrine-glacial and glacial loams and sandy loams.

During the survey period, groundwater was discovered at a depth of 0.80-1.60 m. The waters are free-flowing. The levels discovered during the drilling process can be attributed to average annual levels.

The maximum long-term amplitude of groundwater level fluctuations is 1.50-1.80 m.

In unfavorable periods of the year (the period of rains and intense snowmelt), one can expect the appearance of waters of the "perch water" type in bulk soils at the marks of the day surface.

2.5. Residential building NHX is designed as a sectional type. It consists of fifteen sections. It has a complex configuration in plan, with dimensions in the axes A - K8: 218 m; in axes 1 - K2: 95 m. The projected building of a variable number of storeys: 16-24 floors.

4.14. Production of works in winter conditions.

When preparing a construction site and facilities under construction for work in winter conditions, it is necessary to provide for special measures, as well as methods for transporting and storing materials, semi-finished products and structures.

Earthworks are allowed to be performed, if necessary, according to a special project for the production of works in accordance with the instructions of SNiP 3.02.01-87 "Earthworks, foundations and foundations". The development of frozen soil with a single-bucket excavator without preliminary loosening is allowed with a frozen layer thickness of up to 0.25 m. When freezing to a great depth, the soil must be prepared in one of the following ways: protecting the soil from freezing, thawing frozen soil, loosening frozen soil.

The method of preparation should be selected and justified in the PPR, depending on the scope and conditions of work, the timing of their implementation and the availability of equipment.

Perform concrete and reinforced concrete work in accordance with the instructions of the Section "Work at negative air temperatures" SNiP 3.03.01-87. When transporting the concrete mixture, it is necessary to take measures against its cooling on the way and during overloads, for which the container is insulated and warmed up, and in case of severe frosts and snowfalls, the concrete mixture is covered with a tarpaulin. Places of loading and unloading of the concrete mixture are protected from the wind. Concreting of monolithic structures is carried out using electrical heating of concrete. At the same time, the formwork of the structures is insulated. Concrete electric heating points are being set up on the construction site. The strength of concrete required for further work is specified in the working drawings.

Insulating and finishing coatings must be carried out in accordance with the instructions of SNiP 3.04.01-87. Insulation and roofing works are allowed to be performed at an ambient temperature of up to minus 30 °C (work with the use of hot mastics - at an ambient temperature of at least minus 20 °C, with the use of water-based compositions without antifreeze additives - at least 5 °C) . At the same time, it is recommended to perform roll roofing in only one layer, and the remaining layers are performed in the warm season after inspection and, if necessary, repair of the first layer. Conduct work subject to the adoption of safety measures (temporary fencing of the work site, the use of safety belts, the supply of overalls, shoes, etc.), which are additionally developed in the PPR.

Internal finishing works should be carried out at a positive temperature of the environment and surfaces to be finished not lower than 10 ° C and air humidity not more than 60%. This temperature in the room must be maintained around the clock, at least 2 days before the start and 12 days after the end of work.

5. Basic provisions for instrumental (geodetic) control of construction

Production quality control should include input control of design estimates, products, materials and semi-finished products; operational control of individual construction processes or production operations and acceptance control of construction and installation works. At all stages of construction, in order to verify the effectiveness of previously completed production control inspection control should be selectively carried out by special services or commissions specially created for this purpose. Based on the results of production and inspection quality control of construction and installation works, measures should be developed to eliminate the identified defects. During the control and acceptance of works, the following are checked:

- compliance of the applied materials, products and structures with the requirements of the project, GOST, SNiP, TU,

- compliance of the scope and scope of work performed with the project,

- the degree of compliance of the controlled physical, mechanical, geometric and other indicators with the requirements of the project,

- timeliness and correctness of production documentation,

- elimination of shortcomings noted in the work logs during the control and supervision of the implementation of construction and installation works.

Geodetic instrumental control at the site is carried out in strict accordance with the requirements of SNiP 3.01.03-84 "Geodetic work in construction", GOST 22268-76 and GOST 24846-81. It is performed when:

- creation of a geodetic center base for construction (performed by the customer),

- layout works during the construction period (performed by the general contractor),

- control of the accuracy of the geometric parameters of the object under construction.

All geodetic work on construction must be carried out in accordance with the projects for the production of geodetic works (PPGR). The points of the geodetic base are fixed by permanent and temporary signs. Permanent signs are laid for the entire period of construction and installation works, temporary signs - according to the stages of work (earthworks, foundations, underground and aboveground parts of the building).

The planned basis is created by the methods of triangulation, trilateration, polygonometry of the building network and their combinations.

The height base is created by geometric leveling.

To fix the points of the geodetic staking base, it is necessary to use the types of signs provided for by SNiP 3.01.03-84, specifying in the PPGR the depths of laying and the design of signs for fixing the axes.

During construction, it is necessary to monitor the stability of the signs of the planned base up to 2 times a year and the high-rise base up to 4 times a year.

The location of the signs is given on the Stroygenplan sheet. After payment is confirmed, the page will
