Construction is a very serious area of modern urban development. This area has a wide range of work performed, control by the administration, supervisory authorities and requires precise, impeccable organization. In addition, construction must ensure the safety of the work process, promote labor productivity, and be technically feasible. Therefore, the entire preparatory part and the construction itself are regulated through regulations. These are requirements, rules, standards that establish the order and framework for carrying out construction activities.
What is project documentation
Before you begin production work, it is necessary to draw up. It will allow you to determine the plan for the future structure, calculate all the necessary loads, which will guarantee the safety of the structure, determine the amount of required material, costs, attraction of labor and equipment. Also at the preliminary stage, projects are drawn up that are responsible for organizing traffic and the entire construction process. Special attention is paid to the work production project (WPP), which is aimed at achieving the goals of ensuring the safety of persons carrying out work and located on the construction site. PPR in construction, what it is, is determined by sets of norms and rules governing a certain type of work performed. Often, the PPR is not fully developed for the entire facility due to its large volume, so it is formed from several parts and divided by type of work. These may be separately developed technological issues of scaffolding, roofing, installation of any structural elements, etc.
Why do you need a production project?
The requirements for PPR in the construction of houses are established by SNiP 3.01.01-85, which sets requirements and provides explanations for the development of a project necessary to begin construction of a house. The purpose of its creation, as the document prescribes, is to develop methods for construction activities for their effective implementation, reducing the cost of materials, labor costs, and the use of construction equipment.
Who can develop PPR
The development of PPR in construction requires the people who work on it to have appropriate education, the ability to use software, etc. Because a correctly prepared project will significantly improve the quality of work and reduce the duration of construction of the facility. This is important in the modern construction industry, which is rapidly developing, introducing new technologies, methods, new equipment and equipment.
What is needed to create a PPR
To begin work, construction work will be required. What it is and how to compose it is defined regulatory documents. To develop a project, specialists will need a number of documents on the basis of which a safe construction project will be created. The first thing you need is a task that is created taking into account the needs, wishes, requirements of standards, and building conditions of the customer. An executive plan for the planned facility and a construction project are also required.
Information is provided on the use of special machinery, equipment, labor, materials at the site, indicating suppliers. Data on the study of already commissioned and used real estate objects is provided, and regional characteristics for PPR in construction are also taken into account. What is it and what is it for? This is necessary so that the project is developed taking into account all the subtleties and possible negative natural factors. Information is used about the state of ambient air temperatures, its changes for specific periods of construction, the level groundwater, humidity and other indicators that are important and can affect the progress of construction.
What does a production project consist of?
The composition of the PPR in construction is provided for by a set of norms and rules, which indicates the need to contain three documents in the project. This is a general construction plan (stroygenplan), and information that shows the features of construction, calculations, explanations, justifications. SNiP reveals in detail the content of these documents, fully describes the development scheme, requirements, the presence of certain indicators and calculations. Briefly describe the project blocks general concepts, to present a vision of what PPR consists of in construction. What it is and what it consists of needs to be known to those involved in its development, because each of the three main elements of the project is completed from a number of other constituent documents.
Work schedule
This is a kind of backbone, a model for the future PPR, because the reliability and quality of the future project, as well as the success of its implementation, will depend on its competent development. SNiP PPR in construction makes it clear that the calendar document is key in the entire project, because it establishes the sequence of work performed, which makes construction more rational in the execution process. It also elaborates and specifies all the deadlines, stages, periods, and sequence of work. A ready-made calendar plan makes it possible to proceed to the development of the next document included in the project of the facility.
Construction master plan
At this stage, it is initially necessary to consider and select the most suitable option for organizing the construction site, which will minimize construction costs. Also, the construction plan aims to create conditions for the implementation construction work which must meet safety requirements.
The plan must define the construction site area and take into account nearby buildings and structures. They should also provide for the construction of temporary buildings within the development boundaries necessary for the implementation of construction activities. The presence of existing utility systems near the construction site and the creation of temporary communications to support construction are being explored. It should be taken into account that when organizing work it will be necessary to install power lines, water supply and sewerage. The need will arise for access roads, maneuvering of large equipment, a tower crane and the delivery of materials to the site. The construction plan must provide a place for storing building materials, safe installation of the crane, its movement across sections of the site, and take into account the possibility of lifting to any part of the facility under construction.
Explanatory note
No less important than the rest is a component in PPR. The construction of a house can meet safe requirements only if the project is properly drawn up, and includes vital information. All characteristics that provide for the complexity of construction are specified. A number of information on maintaining and protecting the environment must be included.
Contains a document justifying the required areas, buildings on the site, communications, lifting mechanisms, equipment, and machinery that were indicated in the master construction plan. You can clearly see in the note all the calculations proving the needs, as well as the economic indicators of construction.
Construction is an important area of development for the country and private business. This area is controlled by the administration and executive authorities, regulated by current legislation and regulations. legal acts. They contain a set of norms, rules and mandatory requirements for organizing the activities of contractors and crews.
Let's consider defining one of the mandatory items that the developer must have in advance. What is PPT (territory zoning) and work project (WPP) in construction - this is a package of technological and administrative documentation, including a master plan, decisions on labor protection, industrial safety. Based on them, work is carried out in a standard environment and conditions when there is a likelihood or influence of hazardous factors at the site where construction, reorganization, technical transformation of buildings is taking place, as well as the commissioning of hazardous facilities.
It is being developed for the construction of a full-fledged building or local parts:
- roof, balcony, additional greenhouse;
- underground premises;
- a flight of stairs;
- floors.
It is also possible to develop for individual technically complex construction, installation and repair work during the preparatory period.
The general contractor or a responsible company with a license for the type of activity provided is responsible for its implementation. The head of this organization approves the project and no later than 2 months before the expected start of work, transfers it to the construction site. If the activity is carried out at an existing enterprise, the document must be agreed upon with the client.
Package development
Compilation is carried out in accordance with occupational safety and industrial safety requirements.
To do this prepare:
- POS (POS – point of sales – place of sale);
- materials of technical inspection of structures subject to reconstruction, with analysis results and conclusions, as well as established requirements for work under operating conditions of the premises;
- the mechanization base existing in the organization;
- confirmation special conditions, potentially unsafe production factors;
- basic working documentation.
What is included in the development of PPR in construction
To guarantee the safety of the future building it is necessary precise definition design plan, load calculation, cost of funds, attraction of special equipment and labor. Therefore, when drawing up a project, they rely on:
- Inventory of technical equipment, equipment for installation.
- General construction layout. The boundaries of the object, the location of mobile and erected structures, paths, underground and ground utility networks, communications.
- Schedules for the receipt of raw materials and equipment at the site, the movement of workers on it.
- Calendar schedule. It establishes the deadlines allotted for the implementation of the assigned tasks, their sequential implementation and priority.
- Technological maps. Decisions made by the commission regarding the conduct of geodetic activities and safety issues.
- Schemes for correct slinging of loads.
- Explanatory note. It is the rationale for the adopted proposals on production issues and the costs of energy resource needs. It also stipulates the conditions for assigning mobile buildings and mechanized units to the site, lists measures to ensure the complete integrity and safety of property and protect objects from damage, measures and actions taken to protect the environment.
The preparation of PPR in construction is regulated by legal acts adopted by executive authorities.
Software for developing project documentation
Most contracting organizations are switching to automated system accounting. Software significantly simplifies the task and reduces the time spent. This process almost eliminates human factor, which is the most common precedent for accidents.
Utilities that are used to computerize the creation of a construction work plan:
- Microsoft Project.
- A combination of SmetaWIZARD + PlanWIZARD.
- Excel.
- Rillsoft Project.
- Hector: Designer – Builder.
- and others.
A requirement for a number of software is the presence of AutoCAD, NanoCAD, Compass. The products sold by ZWSOFT are also suitable for this. This software is an analogue of ACAD, but its cost is significantly lower, so both large companies and small organizations, educational institutions.
Why is PPR needed in construction?
The purpose of the creation is to develop methods of construction activities for its most efficient implementation, as well as possible reduction in the cost of materials, human resources and the use of special equipment. The requirements for documents are established by SNiP 3.01.01-85, which provides explanations for the correct preparation of a package of papers for the possibility of erecting a building.
Other regulations, bills and resolutions:
- PPB 01-93 “O fire safety in the Russian Federation."
- SNiP 12-04-2002 “On labor protection in construction.”
- SNiP 12-03-2001 “Part 1. General requirements”.
- PB 03-428-02 “Code of rules for the construction of underground facilities.”
How to develop PPR in construction on a computer
This is a labor-intensive and long process. It requires special training and sufficient qualifications. Due to a lack of experienced workers and reduced deadlines for registration before project documentation and PD, which sometimes affects the quality of task completion, organizations are increasingly turning to modern information technologies.
To make a layout using a program, decide what components it should include. General wishes of most contractors responsible for drawing up the package of papers:
- current GESN, EniR with the ability to set your own prices;
- transfer of data from estimates of other programs;
- critical path calculation;
- deleting and adding roads, buildings, equipment;
- automatic drawing master plan, additional schemes (electrification, water supply, communications) with minimal human participation;
- calculating the costs of energy, special equipment, materials and other resources;
- accounting for cycles of completed volumes with the designation of repetition of identical work in the schedule;
- release explanatory note;
- entering the contractor's equipment into the database.
Take advantage of a tool that makes work easier and cheaper by providing ready-made, tried and tested solutions, automating the design of graphic and text documents.
Taking into account the wishes of specialists, computer software developers are offering more and more products that are in demand.
Before drawing up a construction design plan using a PC, consider 3 basic principles that serve as the foundation for most design utilities:
- Organization of an information base, including methodological and regulatory parts necessary for the correct formation of incoming and outgoing data.
- Possibility of structuring and systematizing production goals and objectives.
- Automation of specific PPR tasks using software modules with graphical components. They can be implemented as an add-on to the latest versions of the ZWCAD or NanoCAD package. Calculation ones can work in C++ and FoxPRO.
Using cranes as an example, let’s consider what these plugins are required to do:
- form technological schemes;
- select a crane based on certain parameters and load lifting height;
- record the needs for inventory facilities;
- design pits automatically and calculate water reduction;
- determine an effective option for transport and earth-moving equipment;
- calculate and select lighting fixtures;
- analyze loads and electricity consumption;
- draw a crane, tying it to objects located on the site.
An important point for the designer is the prompt provision of an information base, which includes:
- methods that determine the need for materials, special equipment, technical equipment, various equipment and inventory;
- requirements for warehousing, safety, transportation of raw materials and special structures, installation of scaffolding with examples of their possible location;
- instructions on safety and health, fire and environmental safety;
- terms of production control of work performed and their quality;
- other information on PPR issues.
As a result, the data obtained using the program must represent organizational and technical documentation, drawn up in accordance with current standards and legislation - in the form of calculation, text and graphic solutions. This is an adaptation of GeoniCS for the ZWCAD 2017 PRO version. It is intended for design and survey work - the production of drawings in which the necessary stamps and explications are filled in and can be divided into sheets of a certain format.
1. water supply;
2. storm and ordinary sewerage;
3. heat saving;
4. gas pipeline.
Performs many tasks - creates a basic plan and a summary plan for utility networks, details wells, creating a table, plots geological wells on a diagram.
Choose a convenient program to make your work easier.

PPR is further development main decisions taken in the PIC. PPR is developed to determine the most effective methods for performing construction installation work, reducing cost and labor intensity, reducing construction duration, increasing the degree of use of construction machinery and equipment, improving the quality of construction and installation work. Construction without PPR is prohibited.
The work project is developed by a construction and installation organization or a specialized one designed to provide technical assistance and introduce new technologies.
PIC and PPR should be based on progressive engineering solutions, taking into account modern level industrialization of construction production, new methods and forms of its organization. The nomenclature and volume of design documentation, as well as the degree of its detail, are determined by the nature of the facility under construction and the complexity of specific conditions.
A work production project is a documented model of construction processes for the construction of facilities from the beginning of preparatory construction and installation work to the commissioning of facilities. The types and volumes of construction and installation work for each facility, the sequence and timing of their implementation, the need and timing of receipt of all types of material and technical resources, construction machines, and workers at the construction site are determined, and rational technology and safe conditions for performing the work are also provided.
The approved PPR is the basis for operational planning, control, regulation and accounting of construction production. PPRs are developed with the aim of regulating the implementation of construction and installation works using the most effective methods with the study of the optimal composition of teams of workers, sets construction mechanisms and manual machines that reduce construction duration, reduce labor intensity, cost and improve the quality of construction and installation work.
Source documents for the development of the PPR: assignment for the development of the PPR, PIC; working documentation for the construction of the facility; estimate for the construction of the facility and summary construction estimate; initial data on the availability and capacity of enterprises of the construction production base, the capacity and workload of existing construction and installation general contracting and subcontracting organizations and their staffing, the composition of the fleet of construction machines, vehicles and other types of transport; information on the procedure and timing of delivery of technological, energy, plumbing and other equipment and special materials by the customer; supply data building structures, products, materials; other information necessary for the development of project documentation for construction and installation works.
The PPR should provide for the introduction of rational methods, best practices and scientific and technical achievements in the field of construction production.
The decisions made in the PPR should ensure: reduction in the labor intensity of work due to comprehensive mechanization and hand-held machines; reducing the duration of construction due to the maximum time combination of general construction and specialized work and reducing the duration of each work; increasing worker productivity through the implementation best practices organization of workplaces; reducing the cost of construction and installation work; compliance with labor protection, safety regulations, industrial sanitation and fire safety.

The PPR for the implementation of certain types of work should consist of a work schedule, a construction master plan, a technological map and a brief explanatory note with the necessary justification and technical and economic indicators.
The PPR for the preparatory construction period should contain:
- work schedule for an object or type of work;
- construction master plan;
- technological maps;
