2. TECHNOLOGY FOR CONSTRUCTION OF STRUCTURES

2.1 Previous work

By the time the construction of the metal frame of the showroom begins, the following work must be completed at the site:

- installation of bored piles;

- cutting out trenches for grillages;

- arrangement of grillages;

- backfilling;

- construction of an inspection hole.

All work must be carried out in accordance with the working design and documented in Certificates.

2.2 Preparatory work

Before starting work on the installation of metal structures, you should:

- clean the grillages from dirt, sediment and concrete deposits;

- incoming quality control of metal structures entering installation;

- use a pencil or marker to mark the marks of the installation, longitudinal axes on the side faces of the structures.

2.3 Installation work

Installation of structures should be carried out using grips in accordance with sheets of graphic part 2-5. It is preferable to install elements “from wheels”. If necessary, use an area in the northern part of the construction site for storing elements (see Stroygenplan).

As the columns and half-timbers are installed, sections of load-bearing reinforced concrete walls (elevator unit) should be erected.

Before installing the load-bearing beams of the coating at elevation. +6,800 (top of the column, bottom of the beam) within grips 1 and 2, it is necessary to mount the beams of the mezzanine floor at elevation. +3.585 (top of the beam) and erect a section of monolithic flooring.

2.3.1 General sequence of work on installing a metal frame:

1. At the storage site, prepare columns, beams and connections for installation.

2. Install the columns in the design position. Install each column in the following technological sequence:

- Perform slinging of the column.

- Raise the column above ground level by 300 mm, make sure that the slings are securely fastened.

- Perform tilting of the column by lifting and simultaneously turning the boom (or changing the reach) to the stop so that the vertical position of the crane's cargo ropes is maintained.

- Use a LIEBHERR 26K.1 crane (can be replaced with one of similar characteristics) to move the column to the installation site. The column should be delivered to the installation site at a height above 2300 mm away from obstacles encountered along the way.

- When installing a column on a foundation, clean the threads of the anchor bolts from rust and concrete residues with steel brushes, run them with a drill with the appropriate diameter and thread pitch, and check for axial marks.

- Install the column on temporary mounting pads, ensure temporary fastening and alignment of the column on the anchor bolts with paired nuts that fix the position of the base plate.

- Carry out design fastening of the column to the foundation. If necessary, brace the column in two mutually perpendicular directions using struts.

- After installation, unstrap the columns.

3. Install the beams in the design position. Install each beam in the following technological sequence:

- Installers must install a scaffold at the location where the beam is to be installed.

- Sling the beam.

- Use a LIEBHERR 26K.1 crane (can be replaced with one of similar characteristics) to move the beam to the installation site. Bring the beam to the installation site at a height of 500 mm from any obstacles encountered along the way.

- The installer should approach the place where the beam is connected to the column from the scaffold and perform their design fastening. Upon completion of work on securing the beam, the slinger unfastens the elements.

4. Mount the connections in the designed position. Install each connection in the following technological sequence:

- Installers should install a scaffold at the communication installation site.

- Perform slinging connection.

- Use the LIEBHERR 26K.1 crane (can be replaced with one of similar characteristics) to connect the connection to the installation site. The connection should be delivered to the installation site at a height above 500 mm away from obstacles encountered along the way.

- The installer from the scaffolding should approach the place where the connection is connected to the beam and column and carry out their design fastening. Upon completion of work on securing the beam, the slinger unfastens the elements.

5. Mount the purlins in the designed position in the following technological sequence:

- Installers should lay temporary flooring from boards 40 mm thick (in two mutually perpendicular layers) along the load-bearing beams.

- Perform slinging of the purlin.

- Using a Liebherr 26 K.1 crane (can be replaced with one of similar characteristics), move the run to the installation site at a height above 500 mm from obstacles encountered along the way.

- The installer should approach the place where the purlin is attached to the beams from the scaffold and carry out the design fastening. Upon completion of work on securing the girder, the slinger unslings the elements.

6. Carry out a visual inspection and draw up a report on the work performed.

Loads must be slinged in accordance with slinging diagrams. For work, slings should be used that correspond to the weight and nature of the load being lifted, taking into account the number of branches and the angle of their inclination; the slings should be selected so that the angle between their branches does not exceed 90°.

Loads must not be moved while there are people underneath them. The slinger can be near the load while it is being lifted or lowered if the load is at a height of no more than 1000 mm from the platform level.

2.3.2 Crane operation

The work is carried out using a quickly erected tower crane LIEBHERR 26K.1 (can be replaced with one of similar characteristics).

Preparation of the workplace

Before starting work with a crane, you must complete the following:

- install stands with sling diagrams and a table of load weights in the crane operating area and at the storage area;

- install safety signs, sign No. 3 along the boundary of the dangerous zone, sign No. 2 along the line limiting the crane service area.

Crane operation when installing columns:

The crane operates with a hook lift height limit of 11.05 m, with a maximum reach of 24 m and a danger zone of 8.3 m when installing elements, as well as with a reach of 23 m and a danger zone of 1.7 m during operations at the storage site and when unloading from motor transport.

Crane operation when installing beams and ties:

The crane operates with a hook height limit of 11.4 m, with a maximum reach of 24 m and a danger zone of 3.6 m, as well as with a reach of 23 m and a danger zone of 1.6 m during operations at the storage site and when unloading from vehicles.

Crane operation when installing purlins:

The crane operates with a hook height limit of 9.2 m, with a maximum reach of 24 m and a danger zone of 3.5 m, as well as with a reach of 23 m and a danger zone of 1.3 m during operations at the storage site and when unloading from vehicles.

During unloading and installation, loads should be moved parallel to the boundary of the danger zone and prevented from accidentally turning around using flexible guy ropes. The lifting height of the hook should be limited to 6.0 m.

Prohibit the presence of people and the storage of cargo in the danger zone. Measures for the safe operation of cranes should be issued as a supplement to production and job descriptions for personnel operating load-lifting cranes and engineering and technical workers.

Close access to the work area for unauthorized persons not directly related to the work, for which purpose, before starting the crane operation, place a signal fence along the border of the dangerous zone.

Loading and unloading operations

General requirements

At the construction site, reinforcement and formwork elements are unloaded with simultaneous placement on the storage and edging site, individually or in stacks. Dragging loads is prohibited. When storing formwork elements in stacks, lay them in rows in a horizontal position no higher than four rows in height. Spacers with a width of at least 5 cm are laid between horizontal rows.

Before starting work:

- appoint the required number of slingers and signalmen;

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 carrying out work at height. 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 approval certificate in all customer services: labor protection, fire protection, environmental protection, etc., indicating the specifics of the work and safety measures (hot work, work at height, used equipment, 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 - is suitable for all work at height.
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.

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

Today, due to the fact that construction work has become characterized by the highest degree of severity, there is a need for the creation and more responsible development of technological and technical solutions that 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, for excavation work, 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;
• Schedules for receipt of construction materials, products and equipment at the site;
• 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;
  • a list of mobile structures with calculation of the need and justification of the conditions for their location on the 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, specialists take into account various methods of organizing a 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. In addition, the explanatory note provides technical and economic indicators of construction.

You can download the PPR for construction.

Here you can see examples of work projects

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 the construction of 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.

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

Newly purchased equipment that requires installation also needs to develop a work plan. This project describes in detail the progress of work, according to which the installation of technological equipment should be carried out.

Requirements for PPR for installation of equipment

The document must be in full compliance with construction standards and regulations. Measures for organizing safety, fire safety, and labor protection must be outlined.

The project for the installation of equipment consists of:

• An explanatory note containing all the details of the requirements for organizing the installation of equipment.
• The calculation and descriptive part, containing unified solutions for installation, assembly methods, describes the necessary types of welding work.

In the lists of installation equipment and fixtures, the planned volumes of activities and the requirements for materials (pipelines, metal structures, etc.) are calculated. The most suitable technologies for specific installation operations are also identified. This also includes a calendar with work schedules.

• A package of drawings and diagrams, including enlarged and technological drawings of the assembly of components and equipment, installation diagrams of lifts, equipment, scaffolding, as well as a diagram for connecting temporary electricity, water, gases and steam. The calculations carried out in the computational and descriptive part determine the required amount of energy resources.

The project for the installation of equipment must be confirmed by all parties who intend to take part in the work.

Why is it necessary to develop a work plan for equipment installation?

To optimize work, reduce its duration and reduce costs, it is advisable to use modern mechanization and technological solutions. For these purposes, any Work Production Project is created.

Installation and construction work must be completed within the agreed time frame. At the same time, it is necessary to ensure fire and environmental safety, labor protection. All this is stipulated in the PPR and is mandatory for execution.

Who should develop the PPR

Development of the Project is the responsibility of the organization installing the equipment:

In the contract construction method, this is the General Contractor.

• When combining the functions of the Contractor and the Customer, this is the Developer.
• To perform specialized or individual types of work, this is a Contractor or Subcontractor.

The chief engineer or the head of the organization performing the installation approves ready-made plans for installation of equipment. Certain types of installation work require the development of separate PPR. They are approved by the contractors and must also be agreed upon with the General Contractor.

If installation work will be carried out on the territory of the enterprise, then the PPR should be agreed upon with the organization operating this territory.

According to the rules, the project for the installation of equipment must be agreed upon, approved and transferred to the construction site two months before the start of the planned installation work.
