Who develops PPR
Projects for the production of works for the construction of new structures or for the reconstruction or expansion of any facility are developed by general contracting construction and installation enterprises. If PPRs are ordered by a general contracting or subcontracting construction and installation organization, then they can be developed by design and technology institutes or design organizations.
It should also be noted that sometimes, when carrying out large volumes of work, PPRs are compiled not for the object as a whole, but for any specific type of work, for example, for the installation of prefabricated structures, for excavation, for roofing, etc. Previously, such documents were called work organization projects (abbreviated as POR), but in the current norms of SNiP 12-01-2004 instead of SNiP 3.01.01-85, they are also called PPR with the proviso that these are projects for the production of specific works. When carrying out such certain types of work related to the conduct of general construction, special or installation work, PPRs are developed by companies that are directly involved in this.
The composition of the PPR
The composition and content of the WEP must comply with SNiP 12-01-2004 "Organization of Construction" and include the following documents:
- Work schedule;
- Technological maps;
- Building master plan;
- Schedules for the receipt of building materials, products and equipment at the facility;
- Lists of technological inventory and assembly equipment;
- Schedules for the movement of workers around the facility;
- Solutions for the production of geodetic works;
- Safety solutions;
- Explanatory note, which should contain:
- justification of decisions on the implementation of certain types of work, including those performed in the winter;
- calculations of networks of temporary engineering communications;
- measures that would ensure the safety of materials, products and structures, as well as equipment at the construction site;
- a list of mobile structures with a calculation of the need and justification of the conditions for their location on the construction sites;
- measures to protect these structures from damage, as well as environmental protection measures.
But it should be noted that only 4 documents remain the main ones in the PPR: the construction plan, the calendar plan for the production of works, an explanatory note and a technical map. Let's consider them in more detail.
The key document of the PPR in construction is, of course, the calendar plan for the production of works. The success of the entire project depends to a greater extent on the literacy of its development. In short, the schedule is a model of construction production, which clearly and precisely establishes the sequence and timing of construction work at the facility.
The second most important PPR document remains the construction master plan (or abbreviated construction plan)
The quality of its preparation primarily determines the reduction of costs for organizing a construction site, which at the same time allows you to create safe working conditions for workers. When developing a construction plan, specialists take into account various ways of organizing a construction site, from which the most rational one is subsequently selected.
The next equally important PPR document is the flow chart, which determines the most optimal methods and sequence for performing a particular type of work. In addition, the calculation of labor costs is carried out here, the necessary resources are determined and the organization of work is described.Technological maps, as a rule, include graphic and text documents, which may include workplace schemes, which indicate the front of work and the boundaries of the sections into which the object is divided. In principle, technological maps can be of three types:
- typical without reference to specific objects;
- typical with reference to typical objects;
- individual with reference to a specific project
And the last important element of the PPR can be called an explanatory note, which, as mentioned above, indicates all kinds of labor protection measures, determines the conditions and complexity of construction, justifies the presence of storage facilities and temporary structures, etc. In addition, the explanatory note provides technical and economic indicators of construction.

The concept and significance of PPR in construction
Each properly organized construction must have well-written construction documentation, which, as a rule, includes the development of documents such as a traffic organization project (abbreviated as POD), a construction organization project (abbreviated as POS) and a work execution project (abbreviated as PPR). All these documents are able to ensure the safety of employees during construction and installation works, ensure the proper organization of the construction of the facility itself, as well as improve the quality of construction work.
This document contains a list of technological rules, requirements for labor protection and safety, and environmental safety as well. On the basis of the project for the production of works, the organization of construction work is carried out, the necessary materials and resources are determined, the deadlines for the completion of work are determined, and possible risks are worked out.
