PPRk (Crane Work Project)

The installation and safe operation of three tower cranes during the construction of a series of monolithic residential buildings is considered. Due to cramped conditions, the cranes operate with a limited service area.

Stationary tower cranes of the Jaso J110N and Jaso J140N brands erect structures of a 19-story building from elevation 0.000 to elevation. +63.000. The cranes are mounted on foundation supports with a slab elevation of -2.200, with tower anchorage.

The maximum load lifted by cranes at a reach of 2.5-15 m is 5 tons, at a reach of 15-40 m - 2.5 tons.

Tower cranes are used at all stages of construction of the underground and above-ground parts of the building, namely:

• for unloading from vehicles and storing materials and products as they arrive at the construction site
• for supplying packs of reinforcement, reinforced mesh and formwork, as well as for supplying concrete in buckets during construction monolithic structures
• for supplying small-piece materials and mortar to the installation horizon
• for supplying and removing construction equipment, equipment, consumables, etc. from the building.

This is an example of a work permit for the excavation of a pit under the protection of a sheet piling fence. Excavation is carried out in 3 stages.

• Stage 1. Work at the level of 135.50÷134.60 is carried out by a Hitachi ZX 200 excavator with a bucket capacity of 0.8 m3 (maximum digging radius - 9.75 m, maximum digging depth - 6.49 m) equipped with a backhoe bucket with loading of soil into dump trucks. With a lag of 4 meters from the operation of the Hitachi ZX 200 excavator, the installation of the strapping belt (1 I-beam N45 B2) is carried out. Installation is carried out using a truck crane according to a separately developed design and maintenance plan.
• Stage 2. Work at level 132.50 is carried out with a Hitachi ZX 200 excavator. At this level, a pit is developed to a design depth of 127.84÷127.84 m, by excavating and moving the soil into a dump truck. With a lag of 4 meters from the operation of the ZX 200 excavator, a spacer structure is made, consisting of a strapping belt (2 I-beams N45 B2), spacers made of pipes 426x10mm in axes 1÷10 and struts, as well as pipes 630x12mm in axes 11÷16. Installation is carried out using a truck crane according to a separately developed design and maintenance plan.
• Stage 3. Excavation of slopes is carried out by developing and moving soil with a Bobcat S330 excavator into the work area of ​​a Hitachi ZX 225 grab. The grab brings the developed soil to the surface and loads it into a dump truck. The Bobcat S330 excavator is released from the pit upon completion of the work by a truck crane according to a separately developed work permit.

At the last stage, the berm soil is excavated under the installed jibs of the sheet pile fencing of the pit using a mini excavator.

Project for the installation of a water pipeline using the auger method

Laying a water pipeline in a case constructed using a closed auger tunneling method. The excavation of a rectangular working pit and a round receiving shaft is also being considered.

Work on laying pipes using auger tunneling is carried out in several stages:

• 1st stage. Pushing the pilot line, consisting of rods and a pilot head, to the length of the interval from the starting pit to the receiving pit. The exact direction of the route is ensured by a system for monitoring the position of the pilot head, information about the position of which is displayed on the monitor screen suspended in the launch shaft.
• 2nd stage. Punching of casing steel pipes and expander mounted in the starting pit on the last rod of the pilot line within the length of the entire interval between the pits. Pushing out working pipes from the starting pit with simultaneous removal of the squeezed out casing steel pipes in the receiving pit. The casing pipes are being pressed with a drilling head at the head of the pipe string, which serves to develop soil in the face; soil is transported from the face to the bucket in the starting pit by a screw conveyor.
• 3rd stage. Pushing working pipes with a diameter less than or equal to the diameter of the casing pipes, with simultaneous pushing of the casing pipes and screw conveyor links into the receiving pit and their disassembly. When the diameter of the working pipes is less than the diameter of the casing, the construction gap (space) formed between the working pipeline and the inner surface of the excavation must be filled with cement mortar.

PPR for installation of sheet piling and bored piles

An example of a PPR for the installation of sheet piling fencing for a pit in the security zone of a power transmission line (power lines). Performance bored piles: drilling a well with augers, installing the reinforced frame of the pile with a drilling rig, filling the pile with concrete mixture using the bottom-up method.

Drilling of bored piles Ø620 mm is carried out using a Hitachi-based drilling rig

Drilling of each well should begin after an instrumental check of the grades of the planned surface of the earth and the position of the contour axes on the site.

Concreting of piles is carried out by supplying concrete mixture into the well through hollow augers.

As concrete is fed into the well, the auger sections are lifted and dismantled, and the level of concrete in the well must be at least 1 m higher than the bottom of the auger. The distance between the bottom of the well and the lower end of the auger when concreting begins should not exceed 30 cm.

On what basis are you required to have a PPR? List of normative documents.

Friends, need your comments, write if you found what you were looking for, and if you didn’t find it, write what. We want the library to have all possible documents.

Often, when performing work, various documents are required. And even more often they are not at hand. Here is a library of documents necessary for preparing and conducting high-altitude work. You can download it absolutely for free. Today, you may encounter a diametrically different attitude towards papers from your customer: they may not ask for anything, they may ask for a work permit, or they may drag you through all the stages in the most difficult way possible. Let's consider the maximum that the customer can require from the work manufacturer.

What does the procedure for obtaining work at height look like?

1. Certificate of admission issued and signed by the customer. In “severe cases”, the foreman appointed by order signs an admission certificate in all customer services: labor protection, fire protection, security environment etc., indicating the specifics of the work and safety measures (hot work, work at height, equipment used, garbage collection, etc.)
2. Transfer and Acceptance Certificate work front. Drawed up between the Customer and the Contractor.
3. (who will instruct and sign all journals, acts and orders). The person in charge must have valid certificates labor protection, if hot work is carried out - crusts according to fire safety . They may ask for crusts organization of high-altitude work.
4. Work permit drawn up by the person in charge appointed by order (the work permit is signed by the safety manager/chief engineer/general director)
5. All high-altitude workers, welders, electricians should have valid certificates for all types of work performed .
6. Magazines on T.B.(with signatures for the instructions provided). T.B. Instruction Journal It's better to have a new one for each object. All magazines must be bound and stamped. A variety of magazines may be required - on fire safety, electrical safety, etc.

Let's look at all the papers in detail:

1. Certificate of admission —

   Sample of filling out the admission certificate —

2. Transfer and Acceptance Certificate scope of work -
3. Order to appoint a person in charge on occupational safety and fire safety at the site -

   Order to appoint a person in charge in shortened form -

4. Work permit in 2 versions: the text is the same, but in the second version there are more fields to fill out, and therefore it is on 2 pages:

   Work permit for increased danger —

5. Pay careful attention to the crusts - the admission of a high-altitude climber with ineffective crusts shifts ALL the responsibility is on you. Fake crusts are the responsibility of the high-altitude climber himself.
6. TB magazines. On-the-job training log is a journal in the form specified in Appendix 6 to GOST 12-0-004-90 “System of Occupational Safety Standards”. This standard specifies the procedure and forms of training and methods for testing knowledge on occupational safety and other types of activities of employees, managers, employees, students and specialists. It is better to buy them in advance; they are available in bookstores. But if you need it tomorrow morning, you can print it and flash it. The main thing is to tie the thread with which you will stitch at the back, seal it with a piece of paper, put the seal and signature of the safety manager/chief engineer/general there. director. Usually they ask for a log of initial (introductory) briefing and at the workplace. You can fill out both briefings in one log, or you can make two separate ones.
7. Project (plan) of work execution (WPR).

PPR stands for Work Production Project, although it is often deciphered as PRP Plan, but this is incorrect. By downloading files from our library, you can easily customize the templates to suit your high-altitude work, such as:

• installation of metal structures
• facade works
• lifting loads
• any other high-altitude work

Usually PPR is compiled as follows :

1. We meet the customer’s safety engineer and politely but persistently ask him for detailed requirements for PPR.
2. Download the sample file PPR.
3. Fill out the title page.
4. Section 1 - General provisions- Suitable for all high-altitude work.
5. Section 2,3,4 - we briefly describe a specific type of work.
6. If you need volume, download the instructions, intersectoral or Ministry of Emergency Situations, and add as much as necessary.
7. We add applications as required by the customer’s safety engineer.
8. Editing the table of contents.

Every properly organized construction must have a competently compiled construction documentation, which, as a rule, includes the development of documents such as a traffic management project (abbreviated as POD), a construction organization project (abbreviated as POS) and a work production project (abbreviated as PPR). All these documents are capable of ensuring the safety of employees during construction installation work, ensure the correct organization of the construction of the facility itself, as well as improve the quality of the work performed construction work.

Today, due to the fact that construction work has become characterized by the highest degree of severity, there has arisen a need for the creation and more responsible development of technological and technical solutions, which are used in the production of work. That is why the main and most significant document in the system of organizational and technological training becomes the PPR document in construction - download for free, which can be found at the end of this article.

This document contains a list of technological rules, requirements for labor protection and safety and environmental safety, among other things. Based on the work project, construction work is organized, the necessary materials and resources are determined, the deadlines for completing the work are determined, and possible risks are worked out.

Who develops the PPR?

Work projects 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 and engineering organizations.

It should also be noted that sometimes, when carrying out large volumes of work, PPRs are drawn up not for the object as a whole, but for a specific type of work, for example, for the installation of prefabricated structures, excavation, for roofing work, etc. Previously, such documents were called work organization projects (abbreviated POR), but in the current standards SNiP 12-01-2004 instead of SNiP 3.01.01-85, they are also called WPR with the proviso that these are projects for the production of specific works. When carrying out certain types of work related to general construction, special or installation work, PPRs are developed by companies that are directly involved in this.

Composition of PPR

• Work schedule;
• Technological maps;
• Construction master plan;
• Arrival schedules for the facility building materials, products and equipment;
• Lists of technological equipment and installation equipment;
• Worker movement schedules around the facility;
• Solutions for geodetic work;
• Safety solutions;
• Explanatory note, which should contain:
  • justification of decisions on the implementation of certain types of work, including those performed in winter;
  • calculations of temporary utility networks;
  • measures that would ensure the safety of materials, products and structures, as well as equipment at the construction site;
  • list of mobile structures with calculation of the need and justification of the conditions for their location on the sites construction site;
  • measures to protect these structures from damage, as well as environmental protection measures.

But it is worth noting that only 4 documents remain the main ones in the PPR: construction plan, work schedule, explanatory note and technical map. Let's look at them in more detail.

The key PPR document in construction is, of course, the work schedule. The success of the entire project largely depends on the literacy of its development. In short, the calendar plan is a model of construction production, in which the sequence and timing of construction work at the site are clearly and accurately established.

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 for the creation of safe working conditions for workers. When developing a construction plan, experts take into account various ways organization of the construction site, from which the most rational one is subsequently selected.

The next no less important PPR document is the technological map, which determines the most optimal methods and sequence of performing a particular type of work. In addition, labor costs are calculated here, the necessary resources are determined and the organization of labor is described. Technological maps, as a rule, include graphic and text documents, which may include workplace diagrams, which indicate the scope of work and the boundaries of the areas 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 standard objects;
• individual with reference to a specific project

And the last important element of the PPR can be called an explanatory note, in which, as mentioned above, all kinds of labor protection measures are indicated, the conditions and complexity of construction are determined, the presence of warehouses and temporary structures is justified, etc. Besides, in explanatory note technical and economic indicators of construction are given.
