Depending on the complexity of the object, conditions of construction work and socio-economic significance, items can be added, expanded, and have a more detailed structure.

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

• safety and labor protection;
• natural and climatic conditions;
• technical equipment;
• observance of the norms of nature protection;
• providing the facility 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 Project for the organization of construction. And already on this basis other documents, permits and approvals 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 at each site 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, requiring the agreement of the parties and final approval by the state expertise.

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 POS projects in 9 cities throughout Russia

Development of POS for industrial facilities of any complexity

Coordination of PIC projects

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

Unlike the project for the production of work, developed for individual construction projects, the project for the organization of work covers the entire complex of buildings and structures at the construction site. On the basis of the general plan, several PPRs are drawn up, in which the technological process, the rational organization of construction and the expenditure of material, technical and labor resources for the construction of a specific object are considered in detail. Projects for the organization of construction are developed both for whole residential neighborhoods with a diverse infrastructure, large industrial complexes, and for individual buildings and structures. POS is also necessary if enlargement or reconstruction of objects is planned. The construction organization project is a mandatory document for the customer, construction contractors, and organizations responsible for financing and material and technical support of construction.

Initial materials for the development of POS projects

The PIC is developed on the basis of the following source materials:

• Section Architectural solutions (AR);
• Section Constructive solutions (CD);
• SPOSU;
• Geotechnical survey results;
• Technical and economic indicators (TEP) of construction;
• Decisions on the use of materials, technology and resources;
• Information about the supply of building materials and equipment;

Features of POS development

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

Based on engineering calculations (during the reconstruction of facilities - based on the materials of the technical survey) and the necessary design documentation, the POS calculates the total volume of capital investments and construction and installation work, indicating the time of execution, the need for the necessary workforce, taking into account their qualifications and the need for material technical resources. The POS should contain information about:

• solving problems of organizing transport, water supply, sewerage, power supply, communications;
• places of removal (or delivery) of excess (or missing) soil, removal of construction waste;
• quality control and safety of construction and installation works, organization of labor and environmental protection;
• construction in difficult natural and climatic conditions - at low (high temperatures), in mountainous areas, on soils with special properties;
• measures for performing work on a rotational basis, including work schedules, work and rest hours, the composition and technical equipment of the brigades;
• used machines, mechanisms, technological inventory and assembly equipment;
• schemes of storage 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 carrying out 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 to the population;
• main roads or railways, gas and oil pipelines, power transmission and communication lines;
• water management or hydraulic engineering facilities;
• enterprises specializing in the extraction of minerals, other facilities.

The peculiarity of the conditions under which construction is carried out also plays a significant role during the development of the POS. Features in the preparation of documentation are determined 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 parameters that have a major impact on the content of PPR and POS.
The complexity of the process of developing the design of the organization of construction depends on the specific object, its scale and specifics. POSSTROY specialists offer their services for creating projects of any complexity from a small cottage to a large irrigation and drainage or industrial complex. High qualifications, rich experience and prompt solution of problems are the key to successful cooperation with POSSTROY.

The text part of the PIC should contain:

• characteristics of the area at the location of the capital construction facility and construction conditions;
• assessment of the development of transport infrastructure;
• information on the possibility of using local labor in the implementation of construction;
• a list of measures to attract qualified specialists for construction, including for work on a rotational basis;
• characteristics of the land plot provided for construction, justification of the need to use land plots for construction outside the land plot provided for the construction of a capital construction object;

• a description of the features of work in a cramped urban environment, in the locations of underground utilities, power transmission lines and communications - for non-production facilities;
• substantiation of the adopted organizational and technological scheme, which determines the sequence of erection of buildings and structures, engineering and transport communications, ensuring compliance with the deadlines for completion of construction (its stages) established in the construction schedule;
• a list of types of construction and installation work, critical structures, sections of engineering and technical support networks that are subject to certification with the preparation of appropriate acceptance certificates before the production of subsequent work and the installation of subsequent structures;
• the technological sequence of work during the construction of capital construction objects or their individual elements;
• justification of the need for construction in personnel, basic construction machines, mechanisms, vehicles, in fuel and fuels and lubricants, as well as in electricity, steam, water, temporary buildings and structures;
• substantiation of the size and equipment of sites for the storage of materials, structures, equipment, enlarged modules and stands for their assembly. Solutions for the movement of heavy oversized equipment, large modules and building structures;
• proposals for ensuring quality control of construction and installation works, as well as equipment, structures and materials supplied to the site and installed;
• proposals for the organization of a geodetic and laboratory control service;
• a list of requirements that must be taken into account in the working documentation developed on the basis of design documentation in connection with the accepted methods of erection of building structures and installation of equipment;
• justification of the need for housing and social services for personnel involved in construction;
• a list of measures and design solutions to determine the technical means and methods of work that ensure the fulfillment of regulatory requirements for labor protection;
• description of design solutions and measures for environmental protection during the construction period;
• substantiation of the accepted duration of construction of a capital construction facility and its individual stages;
• a list of measures for organizing monitoring of the condition of buildings and structures located in the immediate vicinity of the facility under construction, earth, 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 SPDs of the most varied kinds are based on information taken from the PIC. It is prohibited by law to start construction and installation work without a PIC that has passed the examination in the prescribed manner. Design documentation will be needed not only for the investor, the construction customer, but also for the contractor construction organizations.

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

Stroygenplan
Stroygenplan is an essential part of the PIC project. In it you can see how functionally and rationally the storage areas for materials and raw materials are organized, household, administrative, sanitary facilities, and temporary roads are located. Also, the construction 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 a PIC in general, for a PPR it is concretized. This document, undoubtedly, is one of the defining ones in the organization of competent and timely financing of objects. Also in the calendar schedule, the dependence of construction on local natural and climatic conditions, when the object is in difficult conditions, is presented.

Explanatory note
An explanatory note is an equally important element of construction management projects. From the explanatory note, you can get a detailed idea of ​​all the features of the conditions of 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 the provision of labor resources, engineering support, etc.

Regulatory framework for the development of POS

Construction belongs to the field 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 mandatory presence of which is approved in SP 48.13330.2011, is the PPR - a project for the production of work.

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

APPROVAL OF PIC PROJECTS

The PIC approval process is regulated by the SNiP 1.02.01-85 "Instruction on the composition, procedure for the development, approval and approval of design and estimate documentation for the construction of enterprises, buildings and structures," as well as by departmental building codes. In accordance with these documents, the customer negotiates the POS with the general contractor for the construction and installation organization.

In addition, a number of examinations and approvals of the PIC with other supervisory authorities are carried out, the full list of which depends on the specifics of the object: architecture management; prefectures of administrative units; Directorate of Glavgosexpertiza; sanitary inspection bodies; Department of Fuel and Energy Facilities; Department of Economic Policy; city ​​transport department and other organizations.

We develop projects:

Design application

Construction management projects refer to design documentation (stage "P"). The need to develop a POS is dictated by the Decree of the Government of the Russian Federation No. 87 of February 16, 2008. On the composition of the sections of the project documentation and the requirements for their content.

What is POS

A construction organization project (PIC) is a design documentation, stitched in A4 format, consisting of text and graphic parts. The composition of the construction organization project is determined by clause 23 of the Decree of the Government of the Russian Federation No. 87 of February 16, 2008.

The main task of the PIC is to establish the main parameters of future construction, such as:

• determination of the required capacities power supply construction;
• identifying the necessary water needs for the construction period;
• calculation and placement of temporary household buildings;
• location temporary roads and storage areas;
• defining prescriptive construction time;
• placement of the main construction machinery;
• definition stages and queues construction.

POS composition

In most cases, the POS is developed in accordance with the requirements of the Decree of the Government of the Russian Federation No. 87 dated February 16, 2008. For especially complex and critical facilities, the POS composition can be expanded according to the Terms of Reference (TOR) agreed with the Customer. Thus, the composition of the PIC is subdivided into normative, supplemented and expanded.

Normative composition of POS

The PIC in its standard form consists of the following main elements:

The supplemented composition of the POS

POS in augmented form consists of the following main elements:

• an explanatory note indicating the main sections and calculations;
• construction plan for the main construction period;
• section of the building and cranes;
• construction schedule;
• annexes to the project - permits (SRO, attestations).

Extended composition of POS

An expanded POS consists of the following main elements:

• an explanatory note indicating the main sections and calculations;
• construction plan of the zero construction cycle;
• construction plan for the main construction period;
• section of the building and cranes;
• technological schemes for the main work processes;
• drawings of temporary structures (if necessary);
• construction schedule;
• annexes to the project - permits (SRO, attestations).

POS development

POS development is quite a responsible job even for a small object. Despite the mandatory examination of the Design Documentation (including PIC), some Companies do not pay due attention to this section. Competent development of POS is built in the following order:

1. Stroygenplan (construction master plan) - the most important part of the PIC, deciding the organization of the construction site and global safety issues.
2. Calculation of construction duration - (section of the textual part of the project) the task of the section is to correctly calculate the construction time of the facility, and on this basis, such parameters as the need for workers, temporary household structures, construction machines and engineering support.
3. Other sections of the project - the full text part and the Construction Schedule (Construction Schedule).

Stroygenplan POS

The construction master plan as part of the PIC should solve global issues of organizing the construction process, such as:

• construction site fencing and design boundaries;
• location and layout of residential townships;
• location on the plan of buildings under construction and neighboring structures;
• temporary roads, storage areas, wheel washes, checkpoints, fire shields and electrical cabinets, lighting masts, etc.;
• binding of the main lifting mechanisms (cranes) and optimization of their parameters;
• display of restrictions on work by cranes and display of the main danger zones.

Despite the mandatory development Crane production project (PPRk) in the future - the main issues of safe work must be resolved at the stage of the POS - the joint work of several tower cranes (the ratio of heights and outreaches of the booms), the correct binding and selection of the parameters of the cranes (height, reach, lifting capacity). As part of the PIC, it is not allowed to bypass these issues by referring to the PPRk.

Later, at the stage of Working Documentation or before the start of construction work at the facility - based on PIC solutions, a Stroygen plan of stage "P" .

Construction timetable(or Construction Schedule) includes a graphical display of the total duration of work, the duration of individual work ( preparatory work, underground part, aboveground part, finishing, etc.), as well as combined schedules of the need for labor resources - workers. Correctly designed Calendar plan gives an informative visual representation - at what points in time and for the production of which work a certain number of workers, engineers and other personnel are needed.

The schedule is obliged to consider all the key points of construction. In case of resumption of the construction of the object after the conservation, the stages of work of the previous years (before the conservation) should also be displayed on the Calendar Schedule.

Expertise and approval of PIC

All construction organization projects (PIC) undergo an examination of design documentation as part of the general design documentation. The choice of an organization for passing the examination of design documentation is made by the Customer, or the general designer of the facility:

• for objects of national importance (architectural monuments, cultural heritage, etc.) - state examination project documentation;
• for other objects - non-state expertise project documentation.

Who can develop a PIC

Development of POS is possible only by organizations that have an SRO permit for the development of design documentation for capital construction projects.

Although design institutes often do not have their own PIC engineers for high-quality project development, therefore they turn to third-party designers (freelancers). You can read about the benefits and dangers of such a development at

11. Technological sequence of work during the construction of facilities

The technological sequence of works or their individual elements is determined in accordance with the selected organizational and technological scheme for the construction of the facility and the organizational and technological schemes for the construction of the main buildings and structures.

The organizational and technological scheme for the construction of a capital construction facility establishes the sequence of construction of the main facilities, auxiliary and service facilities, external networks and structures.

Organizational and technological schemes for the construction of the main buildings and structures establish the sequence of erection of individual buildings (structures) in their parts (nodes, sections, tiers, floors, etc.).

For residential buildings, the sequence of erection of the building itself, external networks of engineering support, improvement is presented. 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

Excavation work must be done in accordance with the rules
SP 45.13330-2010 "Earthworks, foundations and foundations".

During the construction of a residential building, earthwork begins with the removal of the fertile soil layer in a non-frozen state with its transfer 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 passes of the bulldozer.

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

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

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

When developing a trench with an excavator, the soil must be thrown at a distance of at least 0.50 m from the edge of the trench (pit) in dry and connected 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 no 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 locations depending on the composition of the soil at a groundwater level below the excavation depth according to Table 2.

Table (table number) - Allowable slope steepness of the trench

The development of the trench with a single-bucket excavator should be carried out with the elimination of scallops at the bottom during the digging process, which is achieved by pulling the bucket along the bottom of the trench after mining the bottom.

In the event of the appearance of groundwater, drainage of the incoming water from the reservoir (sump) should be performed, 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 drawn from the excavation through drainage grooves or trays.

The soil in the pit is selected before reaching the design mark -10 cm. The soil is reworked immediately before the start of work on the foundation.

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

Backfilling of trenches and pit sinuses should be done with mineral soil without construction waste, 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

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 concrete mixer trucks.

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

Concrete mixtures should be placed in the concreted structures in horizontal layers of the same thickness without breaks, with a consistent direction of placement in one direction in all layers.

When compacting the concrete mixture, it is not allowed to rest the vibrators on reinforcement and embedded products, ties and other formwork fastening elements. 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. the vibrator pad is the boundary of the already vibrated area.

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

In the event of deformation or displacement of the formwork, concreting must be stopped and the formwork must be repaired before the concrete begins 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 then to maintain a temperature and humidity regime with the creation of conditions that ensure an increase in its strength.

During rain, the area to be concreted must be protected (with plastic foil, light mobile sheds, tarpaulins, etc.) from the ingress of water 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 the setting of the concrete of the previous layer. The duration of the break between the laying of adjacent layers of concrete mixture without the formation of a working seam is established by the construction laboratory. The upper 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 mix.

Control concrete samples should be selected in accordance with table 4 GOST 10180-90 “Concrete. Methods for Determining Strength Using Control Samples ”. Cube curing should 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 journals.

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

Reinforcing steel (rods, wire) and bars, reinforcing products and embedded elements must comply with the project and the requirements of the relevant standards. The dismemberment 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 *.

The blanking of bars of measured 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 reinforcement products should be carried out in assembly conductors.

Blanking (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.

The installation of reinforcing structures should be carried out mainly from large-sized blocks or unified prefabricated meshes with the provision of fixing the protective layer.

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

Non-welded joints of rods should be made:

butt joints - overlapping or crimping sleeves and screw couplings ensuring the uniform strength of the joint;

cruciform - viscous annealed wire. The use of special connecting elements (plastic and wire clips) is allowed.

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

When installing monolithic areas in winter, concrete is cured by the method of electric heating. The electric heating zone should be under the round-the-clock supervision of the electricians on duty.

Acceptance of finished concrete and reinforced concrete structures or parts of structures should be formalized in the prescribed manner by an act of survey of hidden works or an act of 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 Fencing Structures"

Delivery of prefabricated reinforced concrete blocks is carried out by a sidecar with a lifting 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 into the installation area, it is necessary:

–Clean elements of dirt, snow, ice, and metal parts - from rust;

–Apply axial risks and check the presence of marks for the support points of the elements;

- check the correctness and reliability of the slinging.

Lifting, moving and lowering elements should be carried out smoothly, without jerking, swinging and rotating. Prefabricated elements must be installed in the design position with appropriate alignment and the device of design fixings in the nodes.

It is possible to release structures from slinging only after they have been secured.

When performing such operations, the POS must ensure the safety of all operations, correct waste disposal and no harm to the environment. are engaged in design organizations that have SRO membership with admission to certain types of work.

Composition of the construction organization project

The composition of the organization's project and the content of its individual parts are influenced by the complexity and specificity of objects, therefore the composition changes in accordance with a specific situation. The factors of influence include design solutions, the amount 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 performing individual works. The composition of the PIC is influenced by exactly how materials, equipment and various structures will be supplied to the construction site.

The construction organization project includes the following components:

• explanatory note;
• a schedule for performing individual operations and the entire 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 assigned tasks;
• plan of the need for devices, machines, construction equipment and transport with specific information on dates;
• information about the required personnel to perform the work.

The content of the project for the organization of construction of the POS

The most important parts of the project are the work schedule and master plan. If the rest of the components can be present in a truncated form or absent altogether, then these are included in any POS, becoming its basis. All other statements and documents refer to the timetable and master plan as the rationale for their creation.

The timetable becomes the rationale behind the chosen sequence. From the work schedule it becomes clear why such a sequence is the most effective, and in the organization of construction it is of primary importance. The timing of each stage of work is clearly indicated.

The master plan describes the optimal placement on the entire construction site or its individual parts of mechanisms for lifting loads, 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 differs from the similar document for the project of the production of works in a more detailed answer to questions regarding the ways of implementing the tasks.

The explanatory note contains the details of the document on the basis of which the creation of the project begins. This can be a developer's decision, the implementation of a federal target program, a comprehensive program for the development of a municipal formation and other documents. It also contains the initial data for the preparation of documentation, information about the functional purpose of the facility, information about the need for utilities (gas, water, electricity, sewage). The correct implementation of the project allows you not to waste extra time in the future to connect communications that were not taken into account in the original plan. The explanatory note may contain other additional information, the amount of which depends on the complexity of the object planned for construction.

Initial data for project development

The organization's project is carried out taking into account the data and documents, the composition of which is present in the methodological recommendations. When creating a POS, the requirements of building codes, the Town Planning Code, and the relevant Federal laws are applied. The provisions of the Decree of the Government of the Russian Federation of 16.02.2008 N 87 are observed.

In the development of the organizational project, the following initial data are used:

• scheme of planning and organization of a plot of land;
• solutions for architecture and urban planning;
• Constructive decisions;
• design documentation for the projected external networks for the supply of electricity, communications and other communications;
• information about engineering and communication networks located in the execution area, and sources of water supply for the site, electrical energy and the necessary types of communication;
• statement of the number of basic construction, installation and additional types of work;
• a project for the execution of operations for the dismantling of objects (if it is planned to build an existing object on the site or simply demolish and dismantle a production or non-production building).

The initial data is needed to fill in the corresponding sections. Design solutions form the basis of the requirement sheet for specific assembly designs. To describe technological and organizational schemes, a significant amount of information is required; to make the most effective decisions in the process, initial data of several types are used at once. Demolition work is not required for new construction, so the dataset also does not imply the presence of all described items without exception.

The basis for the development of a construction organization project is the customer's assignment with the technical conditions for implementation, which also refers to the number of initial data.

The main goals of drawing up 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 is considered in maximum detail. PIC concerns the entire scope of construction from the very beginning to commissioning.

The purpose of creating a project is the delivery of the object on time. Effective organizational solutions allow you to properly spend the allotted time, eliminate the likelihood of downtime due to problems with the supply of materials, supplying equipment, the inability to install certain mechanisms and structures when necessary. The PIC takes into account the use of modern technologies that allow to reduce the construction time and achieve the quality required by standards and regulations.

The project allows you to solve the following tasks:

• the use of optimal organization methods to complete construction in the shortest possible time;
  development of the design capacity by the date set 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 fast assembly 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 in order not to exceed the standards from the Technical Regulations.

The creation of the project is carried out taking into account the peculiarities of the natural and climatic conditions in the area of ​​construction. Performing 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 the seasonality affects the delivery of 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, work in mountainous areas is characterized by special conditions.

Requirements for the design and content of the POS

The project includes text and graphic components. The explanatory note contains only text, in the remaining sections, graphics can be applied as needed. The graphic part contains diagrams, drawings, plans and other documents in the form of graphics. The text component contains explanations, descriptions, information about the object, reasons for making specific decisions, calculations, links to technical documents and standards used during the design process. Diagrams, figures, graphs and data in tabular form can also be located here.

Carrying out work in a cramped urban environment requires a description of the reasons for the crampedness and methods for performing construction in a designated situation. Safe execution of construction work in a hazardous area requires correct organizational solutions in the form of limiting the movement area of ​​cranes, arranging shelters and other structures to protect personnel and other people, and the use of screens.

The section on construction in cramped buildings includes the following data:

• installation conditions and the specifics of working on a crane at a short distance from the pits;
• the need to close 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 meet the need for personnel and resources. For this, the number of required specialists and the period of their employment, a list of required materials and structures with optimal delivery data are clearly described. The construction organization plan is a guarantee of the completion of construction operations on time with proper quality.

2. The nature of 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 projected object is located in the Pushkin administrative district of St. Petersburg, settlement Shushary, street XXXXXXX, d.xx, lit.X, dwelling house NXX.

The land plot planned for development is located in the area of ​​prospective development on the intra-quarter territory and belongs to the ownership right of LLC Construction Company Xxxxxxxxxxx.

From the north, south and west, the construction site is bounded by farmland lands, from the east, the site is bounded by the existing construction site. The plot 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 prior to the start of construction.

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

The location of the object within the city limits makes it possible to use city roads and engineering communications for the period of construction.

The construction of the facility is expected 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 capacity, a sufficient number of machines and mechanisms, as well as qualified personnel.

2.2. Construction materials, products and structures will be delivered to the facility in a centralized manner by road from industrial enterprises and construction industry enterprises in St. Petersburg and the Leningrad Region according to the following transport scheme:

- Ready-mix concrete - concrete plant LLC "SK" XXXXXXXXXXX ".

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

- sand - from the warehouse of OOO Stroytrans by road transport 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.

(Volkhonskoe highway 118, KPO landfill)

2.3. Brief climatological information.

The city of Saint 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. The nearest suburbs are located on the lowland adjacent to the Neva and its continuation along the bay.

The territory of the city and its environs is under the influence of sea (Atlantic) and continental air masses of temperate latitudes, frequent entry of Arctic air and active cyclonic activity. As a result of the interaction of all climate-forming factors, a climate is formed close to the maritime one, with moderately warm, humid summers and rather long, moderately cold winters. The average annual air temperature is 4.2 ° C, and the period with long-term temperatures is 222 days. On average, there are 31 clear and cloudless days in St. Petersburg, overcast - 172, foggy - 57, semi-clear, with variable clouds - 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, frost). The total amount of precipitation falls relatively little: 650-700 mm per year.

2.4. The engineering-geological and hydrogeological conditions of the construction site are characterized by a complex lithological structure - multilayer vertical stratification of soils, deep bedding of dense (supporting) soil layers. Soils are presented as follows:

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

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

- Glacial deposits - silty plastic sandy loam, 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 refractory loams, 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-hard 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 - heavy and light silty hard clays, dislocated, blue, with thin layers of silty sands, with sandstone fragments. The thickness is 4.00-8.40 m;

- clays, heavy and light, silty hard, blue, with thin interlayers 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, refractory, ferruginous is 1.15 m.

According to the degree of frost heaving, bulk soils belong to medium heaving soils, silty dense sands are highly heaving soils, sands are large, medium density and dense and sands of medium size, dense are practically non heaving soils.

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

During the exploration period, groundwater was discovered at a depth of 0.80-1.60 m. The waters are free-flowing. The levels revealed during the drilling process can be attributed to the 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 snow melting), one can expect the appearance of waters of the "top water" type in the fill soils at the marks of the day's surface.

3. Consolidated construction schedule

3.1. The consolidated construction schedule was drawn up on the basis of the consolidated estimate calculation and the construction time of a multi-storey residential building, taking into account the built-in premises.

The duration of the construction of the projected building was determined in accordance with SNiP 1.04.03-85 * part II chapter 3-5 clause 19; 35 by extrapolation:

Calculation of the duration of the construction of a multi-storey residential building with built-in rooms with 119941 mby extrapolation ( SNiP 1.04.03-85 * part I, page 4, appendix ):

The duration of construction is determined on the basis of the duration of the 22-storey residential building and is 14 months, taking into account the arrangement of the pile foundation, the duration is increased by 4 months.

The duration of the construction of the pile foundation is shown on the calendar chart. Taking into account the maximum combination of works and the use of 2 cranes, the total duration of construction will be 33 months, including a preparatory period of 3 months (laying of external networks).

The terms and sequence of the construction of the building and structures, as well as the volume of capital investments and construction and installation works are given in the "Consolidated Construction Schedule".

The consolidated calendar plan is executed without reference to a specific calendar month of commencement of work.

3.2. The volumes of the main construction and installation works are determined for similar objects and are given in Appendix N 1.

Based on the scope of work, the need for construction in structures and materials was determined and is given in Appendix No. 2.

The volume of construction and installation work and the need for building structures will be specified at a further design stage.

4. A brief description of the methods of production of construction and installation works

4.1. The construction of the facility is being carried out in 2 periods.

The preparatory period includes the following works:

- creation of a geodetic alignment base for construction;

- clearing the construction site;

- installation of temporary fencing;

- creation of a general-site storage facility;

- providing travel to the construction site and organizing the movement of construction equipment along it;

- arrangement of the necessary construction equipment;

- connection of builders' utility rooms to existing utilities.

The main period includes: work on the construction of a department of general (family) practice doctors with built-in premises, laying of engineering networks, arrangement of roads and sites, landscaping.

4.2. Prior to the start of work, the customer must break down and securely secured with signs (benchmarks) a geodetic reference network, from which the general contractor performs work on breaking down the construction grid in accordance with the requirements of the project.

The accuracy of the layout work, the method and procedure for constructing a geodetic base should be carried out in accordance with the requirements of SP 126.13330.2012 Geodetic work in construction. Updated edition of SNiP 3.01.03-84.

4.3. In construction, only inventory devices and fixtures made according to standard designs and drawings of design organizations should be used.

Fire safety is carried out in accordance with the requirements of the "Decree of the Government of the Russian Federation of April 25, 2012 N 390 On the fire regime".

During the period of construction and installation work, it is necessary to provide lighting for work places, entrances and storage areas.

Construction site lighting - floodlight from lamps installed on metal masts.

The approach of vehicles to the construction site is from the 10th lane.

Temporary roads are constructed with a pavement of precast concrete paving slabs 3.0x1.75 m.

It is envisaged to use the existing concrete fence and the installation of a temporary metal fence as a construction site fence. At the entrances to the construction site, information boards are installed in such a way that they are located with the front side towards the approaching traffic.

When leaving, organize a site for washing the wheels of vehicles entering the highway in order to exclude cases of soil contamination of the roadway by machinery and vehicles working in construction. It is recommended to use the "Moidodyr-2" installation for water purification of car washes.

Materials are stored in open storage areas in compliance with safety requirements and SanPiN 2.2.3.1384-03.

Temporary buildings were taken as inventory: mobile cabins-cabins of the VD-2M type. Household premises should be equipped in accordance with SanPiN 2.2.3.1384-03. It is recommended to locate sanitary facilities near the entrances to the construction site.

Household premises are equipped with internal plumbing, sewerage and electric heating. Temporary heat supply at the construction site is not provided.

The construction site should be equipped with the necessary safety signs and visual campaigning.

A comprehensive mechanization of construction and installation works was adopted using mechanisms in two shifts. Construction and installation work is carried out from 8 to 23 hours. Work with mechanisms that produce noise (compressor, centrifugal pump, welding transformer) is carried out from 9:00 to 18:00.

All construction workers are provided with good-quality drinking water that meets the requirements of the current sanitary rules and norms set forth in SanPiN 2.2.3.1384-03. Drinking water is delivered in bottles by road.

The average amount of drinking water required for one worker is determined as 1.0-1.5 liters in winter; 3.0-3.5 liters in summer. The temperature of water for drinking purposes should not be lower than 8 ° C and not higher than 20 ° C.

Food for workers at the facility is provided in specially provided household premises. They provide conditions for warming up and taking cold and hot food.

4.4. Before starting excavation work, it is necessary to call representatives of interested services and owners of utilities in order to determine the actual location of the networks and agree on the methods of work. In the presence of a number of operating cables, earthworks should be carried out under the direct supervision and guidance of the engineering and technical staff appointed by the order. If communications that are not specified in the project are found, stop the excavation work and call the representatives of the customer and the designer to the place.

When carrying out earthworks, be guided by the requirements of SNiP 3.02.01-87.

In the process of performing "zero cycle" work, it is necessary to organize constant technical supervision over the condition of the soil and the observance of safety measures during the work.

Excavation work should be started only after taking all measures to exclude damage to underground utilities.

4.5. It is recommended to carry out earthworks on the object with the following machines and mechanisms:

- planning work - with a DZ-101 bulldozer; since the pit is intended to be open, it is necessary to make an entrance for vehicles with a slope of 1:12.

- soil development - with a VOLVO excavator with a bucket capacity of 1 m with further loading into dump trucks and removal of excess soil at a distance of up to 20 km;

- backfilling of the foundation pit and trenches - with a DZ-101 bulldozer.

Backfilling of the pits (trenches) sinuses is performed with medium-sized sand with layer-by-layer compaction with pneumatic rammers of the TR-1 type.

Before starting work on the construction of the grillage, clean the bottom of the foundation pit (trenches) and reinforce the bottom with a layer of hard rock crushed stone 100 mm thick. Since the pit is supposed to be closed, provide for the device of descents into the pit for workers.

Only after the completion and acceptance of work on the vertical layout, which ensures a reliable rapid drainage of surface waters, proceed to the extraction of pits, trenches and preparation of the base for foundations.

4.6. When developing soil and performing work in pits and trenches, it is necessary to provide for measures to prevent soil collapse. To do this, based on the requirements of building codes and regulations, it is necessary in the PPR, taking into account the geological and hydrogeological conditions of the work site and the load from construction machines and stored materials, to determine the steepness of the slopes of the excavation or indicate a project for fixing the walls of the excavation.

Construction of pits and trenches with slopes 1: 0.67 (depth 2.8 m; soils - loam); in this project, the fastening of the slopes is not required.

For the period of work, construction dewatering is envisaged to be carried out by means of open drainage, with the device of drainage grooves around the perimeter of the pits, the device of sump and pumping of water from the sump with pumps with a capacity of 20 m / h, type C-245, GNOM. The volume of water for the building sinking is 25 m3 / day.

4.7. All work on the construction of foundations must be performed in accordance with the instructions of SNiP 3.02.01-87.

When constructing foundations, it is necessary to use the recommendations of TSN 50-302-2004 "Designing the foundations of buildings and structures in St. Petersburg".

To supply the necessary materials to the place of work, a pneumatic assembly crane KS 35719-1-02 is used. The pumping and laying of the concrete mix is ​​carried out using a Stetter concrete pump. Delivery of concrete mix is ​​carried out by mixers of the ABS-7DA type.

4.8. Work on the construction of the ground part of the doctors' department is planned to be carried out with tower cranes of the KB-473 type with a 30 m boom and a KB-401 crane installed on a 37.5 m long rail track, parallel to the designed sections.

The connection of tower cranes is shown in the Stroygenplan drawing. The danger zone during the operation of a tower crane was determined in accordance with SNiP 12-02-2001, part I "Labor safety in construction" at a height of the projected building of 74 m and is 11 meters.

The placement of temporary buildings and structures is to be specified on the spot.

4.9. When erecting monolithic reinforced concrete structures of the projected building, the construction organization project provides for the sequential execution of formwork, reinforcement and concrete work.

Placement of concrete in the structure must be carried out using a concrete hopper.

Delivery of concrete mix is ​​carried out from the concrete unit using concrete trucks. During the period of concrete work, it is necessary to carefully monitor the technology for preparing the concrete mixture, its placement, selection and testing of control samples of concrete, while the control samples must be stored and gain strength under the same conditions as the concrete placed in the case.

Before concreting, the formwork surface must be free of debris, dirt, oil, snow and ice.

Concrete mixtures should be placed in the concreted structures in horizontal layers of the same thickness without breaks, with a consistent direction of placement in one direction in all layers.

Laying of all subsequent layers of concrete mixture is allowed before the beginning of the setting of the concrete of the previous layer.

The upper level of the concrete mix should be 50-70 mm below the top of the formwork panels.

The laid concrete is compacted with surface vibrators of the IV-91A type or deep vibrators of the IV-112 type.

When concreting monolithic floors, it is advisable to use inventory multiple-turnover formwork of the "Dokaflex" or "Alumasystem" type.

Reinforcement of structures is envisaged to be carried out with pre-prepared grids and spatial frames.

4.14. Work 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 of transportation and storage of 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: by protecting the soil from freezing, thawing the frozen soil, loosening the 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.

Concrete and reinforced concrete work should be performed in accordance with the instructions of the Section "Work at subzero 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 for loading and unloading concrete mix are protected from the wind. Concreting of monolithic structures is carried out using electric heating of concrete. At the same time, the formwork of the structures is insulated. On the construction site, concrete electric heating points are being set up. The concrete strength 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 work is allowed to be performed at an ambient temperature of up to minus 30 ° C (work with hot mastics - at an ambient temperature of at least minus 20 ° C, using water-based compounds 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 carried out in the warm season after inspection and, if necessary, repair of the first layer. The work should be carried out 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.

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

Work on the construction of the office building and utilities shall be carried out in strict accordance with the safety rules set out in SNiP 12-03-2001 part 1 and SNiP 12-04-2002, part II "Labor safety in construction".

Operation of tower and jib cranes should be carried out in accordance with the requirements of regulatory documents approved by the Gosgortechnadzor of Russia.

The work of construction mechanisms: a compressor, a welding transformer, a centrifugal pump, accompanied by sound effects, must be performed from 9 to 18 hours in accordance with SanPiN 2.2.3.1384-03.

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

Production quality control should include incoming 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 check the effectiveness of previously performed production control, inspection control must 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 work, measures should be developed to eliminate the identified defects. During the control and acceptance of works, the following are checked:

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

- compliance of the composition and volume 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,

- the timeliness and correctness of the production documentation,

- elimination of the shortcomings noted in the work logs during the control and supervision over 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 works in construction", GOST 22268-76 and GOST 24846-81. It is executed when:

- creation of a geodetic alignment 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 erected object.

All geodetic works at 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 with permanent and temporary signs. Permanent signs are laid for the entire period of construction and installation work, temporary signs - according to the stages of work (earthworks, foundation, underground and aboveground parts of the building).

The planning base is created by the methods of triangulation, trilateration, polygonometry of the construction network and their combinations.

The height base is created by geometric leveling.

To fix the points of the geodetic alignment base, it is necessary to use the types of signs provided for by SNiP 3.01.03-84, specifying in the PPGR the depth and design of the signs for securing 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 confirming payment, the page will be
