We make doors in the load-bearing wall with our own hands. Subtleties of working with a load-bearing wall. Coordination of the opening in the load-bearing wall Installation of the opening in the load-bearing wall

Many homeowners, planning a thorough renovation of an apartment, decide to redevelop it by equipping an opening in bearing wall. Such a need may arise whether you decide to increase the size of the bathroom, combine the kitchen with the living room or turn the apartment into a studio. For residents of panel high-rise buildings, opening openings in load-bearing walls is not only a problem in terms of attractive design. Redevelopment will require a competent technical approach, coordination with utilities, obtaining permits and following hole punching technology. In this article, we will look at how to make and legalize an opening in a load-bearing wall.

A load-bearing wall is a wall that supports the floors. Design panel house suggests the presence of such blocks as vertical support for the slabs. Such dismantling without installing supporting mechanisms, the slabs on top will crack, as a result of which cracks will go along the floor and walls of the apartment above you. If the problem is not eliminated in time, the building may collapse.

As you can see, the main walls are extremely important element in the structure of the whole house. You can determine their location of these thanks to the housing plan, which is indicated in the data sheet. You can familiarize yourself with the scheme at the Bureau of Technical Inventory or at the Housing Office. On the apartment diagram, the main partitions will be highlighted with thick lines.

If you did not get access to the necessary documents, you can try to identify such a wall yourself. Pay attention to the thickness - as a rule, bearing plates are wider. Almost all load-bearing blocks are located at the junction of apartments and at the junction of an apartment and a flight of stairs.

If you are not sure whether this wall is solid or ordinary, remember: expanding the opening in the load-bearing wall in any case will require a special permit, and the specialists from the Housing Inspectorate who will issue it will provide an explanation on this issue.

Is an opening allowed?

You can make an opening in many cases. Often, apartment owners hear a refusal. There are several reasons for the decision:

Outdated load-bearing structures of the entire building. The fact is that every house has its own age, and if yours is over 20 years old, and overhaul has never been made, then making an opening in the load-bearing wall of the house is fraught with negative consequences.
The door in the load-bearing wall on the floor above, below will make it impossible to redevelop your apartment. It is important to pay attention to the location of such holes - they should not be exactly on top of each other.
Another reason for the refusal is the number of storeys of the apartment. There is maximum pressure on the apartments on the first and second floors, therefore, here the probability of obtaining permission to cut a hole is minimal.
The presence of construction defects. In houses commissioned with violations of construction technology, there are discrepancies in interpanel seams, gaps between ceilings and blocks, and other defects. In such cases, you will either receive a categorical refusal, or require additional reinforcement of the wall.
House wall material. In houses with brick walls, it is easier to obtain permission to punch a hole than in panel or monolithic buildings.

Remember: before proceeding with redevelopment, it is necessary to coordinate the opening in the load-bearing wall.

A number of documents and certificates will be required, but it is better to receive them immediately than to experience anxiety after. The Housing Inspectorate, upon revealing an inconsistent redevelopment, has every right to issue you a fine of 3 thousand rubles. The fine is small, but in addition to it, you will still be required to obtain permission. If, according to the results of the check, the cut-out doors in the bearing wall turn out to be in violation, you will be forced to lay a hole, as a result of which all your repair work will be meaningless.

An apartment where there are unauthorized changes cannot be officially sold.

Can it be demolished entirely?

The demolition of the capital partition is definitely not possible and not one specialist will give permission for this. Complete dismantling of supporting structures is fraught with collapse ceiling tiles.

What will be required

To arrange an opening, you need:

design documents. This item refers to the restructuring plan made by the design engineer. To make a rework plan, you must contact the design institute. Even more good option will be an appeal to the design department of the same construction company who was building the house. After the engineer has determined whether it is possible to rebuild the housing and in what form, he will draw up a final plan and issue a package of design documents (resolution on the bearing capacity of walls and ceilings, a floor plan where places for demolition and construction of partitions will be marked, determination of structural elements, affecting the method of strengthening the opening);
statement. The application is written in the housing inspection by you personally on a special form;
documents confirming the ownership of the apartment. The types of such documents vary depending on the form of obtaining housing (privatization, inheritance, court decision, and so on). In any case, you must have a copy of the certificate of ownership of housing, certified by the BTI of the city;
technical conclusion on the condition of the building and the possibility of arranging the opening (issued at the design institute);
permission for redevelopment from the owners of the apartment and the owners of neighboring premises (in writing);
an agreement with a contractor who has SRO approval. Since the partial dismantling of the supporting structure refers to work that is not carried out by the residents themselves, subsequently, to confirm the completion of the redevelopment, you will need to present the SRO approval, which your contractor must have. Without permission, you will not receive a certificate of completion, so it is better not to save on the contractor company.

As a result of obtaining all permits from the housing inspection, the owner is issued a Work Production Log, in which it is necessary to record all stages of the repair. Moreover, it is necessary to record the progress of work honestly and in detail, since deviations and inaccuracies in the journal are the reason for refusing to issue an act of completion to the owner construction works.

As for the technology itself, it will depend on the type of opening - rectangular, arched. In any case, punching a hole is not recommended. It should be cut, which is done with an unstressed tool - a diamond wheel. Cutting with such a tool can be carried out stationary and manually, depending on the material and scope of work. As a result of cutting, less dust is generated and the hole does not need additional processing.

Is it possible to make an opening in a load-bearing wall and how to do it correctly, we will consider in detail. 'Cause it's not that easy this species walls carry a heavy load and making an opening is not so safe.

How to make an opening in a load-bearing wall is detailed below. Also on the video in this article and the photo you can get additional information you need.

Thinking about how to make an opening in a bearing brick wall, you must immediately take into account the documentation. After all, this is an important point.

According to the current legislation, redevelopment with a change in load-bearing structures is prohibited. This will need to be approved.

So:

The application shall be accompanied by a detailed plan of planned changes in the building plan.
The issued permit will allow you to apply to the design bureau for the development technical documentation according to the intended project. Finished project is coordinated in a number of permitting commissions - fire, gas, housing and communal services.
The agreed project is finally approved by the controlling organization. Only after the last resolution, it is possible to proceed with the planned construction work on redevelopment - cutting through an opening in the bearing wall of the building.

Examples of openings and their finishes

This may be an opening in a panel house, or a brick one, it does not matter. It should fit into the overall interior of the room. First of all, you need to choose the desired option, and only then you can get to work.

Let's look at what they are doing and it is likely that this option will suit you:

Redevelopment safety factors

Any work with the supporting structures of buildings must be thoroughly verified and calculated. The walls of buildings experience enormous loads, so the design of the opening must be approached thoroughly. Poor-quality redevelopment in violation of technology can lead to partial or complete collapse of the house.

The calculation takes into account critical factors affecting the final result:

Materials used in the construction of the building
The technical condition of the house, especially the floors
wall thickness
The load on the section of the structure in which it is planned to make a passage
Internal layout of the premises
Dimensions of the planned opening and its correspondence with the dimensions of the wall.

A calculated project, taking into account all the necessary factors, is agreed in the supervisory service. To transfer work doorways start only after the approval of the project.

opening options

The complexity of calculations when designing the transfer of a doorway in a load-bearing wall depends on the configuration of the planned opening. The complexity of construction work and the order of their implementation directly depend on the option chosen.

Standard straight opening	Cut through the wall from a clean slate. The calculation takes into account the existing doorway, which takes part of the load of the supporting structure. According to the project, such an opening is left untouched or bricked
Arch opening	They are more difficult to perform - the bending trajectory is taken into account in the calculation. Of particular difficulty are the calculations of an arched opening in a brick wall, taking into account the placement of masonry joints
Partial passage transfer	Assumes the offset of the jumper of the existing passage in the desired direction. A new fragment of the passage of the required size is cut. The unnecessary part of the opening is laid with bricks.

Hole cutting equipment

Cutting openings in the bearing wall is carried out with a special tool. Ordinary impact sledgehammers, perforators and grinders are not suitable for such a complex procedure - they create too much dust, replaceable parts wear out and break quickly, excessive vibration leads to cracks and chips on the walls.

Cutting openings in load-bearing walls is performed:

Wire cutting machine	A special rope is used as a cutting tool, on which diamond-coated bushings are put on. The rope is designed for huge tensile loads. The installation practically pulls the rope through the structure being cut. Dry and wet cutting is used. The second option helps to avoid strong dustiness.
Hand saw with diamond cutting blade	Water is supplied to the cutting area to cool the tool and prevent excessive dust generation
wall saw machine	operating on the same principle as hand saw, but designed to work with thick walls. Uses running water for cooling
Diamond drill tool	The cutting tool is a special cone-shaped drill with a diamond coating. This tool is also used for drilling holes in the walls for laying various communications.

Making an opening

Preparatory stage: strengthening the future opening

Construction work on changing the design of load-bearing walls is carried out strictly according to an approved project, taking into account design features building. The main objective of the project is to maintain the integrity of the building after moving or punching a new passage.

Before starting work, an early strengthening of the structure of the planned opening is carried out. To do this, strobes are cut out along the perimeter of the passage with a wall chaser, into which reinforcement (channels) is laid.

The gates are not through - these are recesses for the reinforcing element. The cross section of the channel is calculated taking into account various design characteristics building.

Attention: The channels are laid in the recesses made by the wall chaser on both sides of the partition. In order for the laying site to match exactly, markings of the planned passage are made on the wall. According to the marking of the Buryats through holes and transfer the drawing to the other side of the wall.

The channels used to reinforce the structure are pre-cut desired length taking into account the height and width of the planned opening. You will need two pairs for the sides of the opening and two pairs for the top and bottom. On each pair, holes are made in advance through which the channels will be fastened with studs or self-anchors. The distance between the holes is calculated by calculation.

Side pairs are alternately installed in strobes. Through the holes made in the channel pairs, a partition is drilled for mounting hardware. Pairs are pulled together with fasteners. Important: Fasteners must be tightened well using a special power tool or improvised materials.

After installing vertical channels, the operation is repeated with horizontal pairs. The joints of horizontal and vertical channels are fastened by welding on both sides of the future opening. The preliminary reinforcement of the opening is ready.

Main stage: cutting the load-bearing wall

After finishing preparatory phase to strengthen the load-bearing wall, they begin to break through a new doorway. The complexity of the work depends on the material of the walls. brickwork it is easiest to dismantle - it is removed row by row. WITH concrete wall there will be more problems during dismantling due to the presence of reinforcement in the structure.

To cut the opening in the wall, a hand saw with diamond disc. At the site of the future opening, markings are applied that divide the passage into small blocks. According to the marking tool, cuts are made on both sides of the wall. The depth of the slot can be up to 15 cm on each side. Next, the blocks are alternately removed from the opening layer by layer. When dismantling, additional use of a puncher is often required.

When cutting through the opening with a wall saw, the depth of the cut reaches 60 cm, but during operation, access to running water is required to cool the tool and wash out concrete chips and dust.
Sometimes the thickness of the wall of the building turns out to be quite large, especially if the opening needs to be cut through in the foundation or facade part. In this case, a rope installation is used that can quickly cut through concrete or monolithic blocks of any thickness.
You can make an opening in the wall in a third way. To do this, holes are drilled according to the markings on the wall with a diamond drill. Next, you only need to saw the cut fragment into pieces and remove the pieces of the wall from the opening.
Modern tools for cutting openings in load-bearing structures allow you to complete work in a short time with minimal noise and dust.

The final stage: strengthening the structure

The opening cut in the load-bearing wall requires final strengthening with the use of welding and general construction works.

The work is carried out in several stages:

Those parts of the channels along the perimeter of the opening that were inaccessible before the dismantling of the wall are welded on. Important: the legs of the seams during welding must be at least 6 mm, in accordance with established standards.
Pairs of channels from different sides of the wall are connected by transverse steel plates, not more than 50 mm wide and not less than 4 mm thick. The plates are welded to the channels along the perimeter of the structure with a step of approximately 30-40 cm from each other.
A metal mesh is welded onto the channel, along which plaster is applied (see How to do plastering with your own hands). The integrity of the broken plaster coating of the wall is restored - all potholes and recesses are sealed, the channels are additionally strengthened with cement mortar.

Attention: Working with special tools for cutting openings in load-bearing walls requires special professional skills. When operating the equipment, you must follow the safety rules: work in protective clothing and keep your hands away from rotating parts of the mechanisms.

Upon completion of the redevelopment work - cutting a new passage in the supporting structure of the building - the changes made must be recorded and put into operation.
For this selection committee the housing organization will draw up an appropriate act. The document must be certified by representatives of the design bureau that developed the project, the company that performed the work, and the organization that accepted the facility into operation. After approval in all instances, the redevelopment will be officially legalized.

Now you know how to make an opening in a load-bearing wall. Its price will depend on the size of the opening and finishing materials. You can do everything without problems with your own hands, this will reduce costs. And the instructions will help you not to miss anything.

Sometimes for redevelopment in an apartment or a private house, it is necessary to make a new door or window opening. Creating an opening in the load-bearing wall of an apartment brick building is not an easy task. Things are easier with redevelopment in a private house, here everyone is his own boss.

What is a doorway? This is a hole in the wall designed to install the entrance blocks. A fixed fixed element in the interstitial space is called door frame. Often, an arch is made as a decorating element of the interior.

The device of a doorway in a bearing brick wall

Before starting work, you need to contact a specialist who will make a demonstration project with all the calculations based on the wishes of the client. To implement the project, significant costs are required, which start from the amount of 30 thousand rubles. So if you get down to business, you need to foresee a lot. Independent work on the device of the doorway will help the owner save money - it will cost about 15 thousand rubles.

The device of a new opening

it must comply with building codes;
it is desirable to locate the hole in the central part of the supporting structure;
it is necessary to match the upper part with the cement joint of the masonry;
the interwall space up to 0.9 m wide does not need reinforcement operations.

When creating an inter-wall space in a supporting wall, it is necessary to correctly create a reinforcement. Important when changing the design of walls is the safety of life of other residents. apartment building and preservation of the structure of the building itself.

Work order

First of all, you need to decide on the place of organization of additional space for entry and exit. It all starts with markup. You need to decide on the width of the hole, and then begin to determine its future location with a pencil. From the outer wall, you need to measure the distance and make a mark - from here we begin to draw the outline of the future intra-wall space.

A thick wall structure is cut on both sides, so markings on the reverse side will also be necessary.

For their exact match, it is necessary to drill several holes according to the pencil marking (Fig. 1). And then on the other side connect all the holes with a pencil line.

Rice. 1

The above manipulations should be carried out when using the building level, triangle and ruler.

Since we will make space in the load-bearing wall of a brick house, it is necessary to take care of auxiliary partitions and lintels in advance (Fig. 2).

Removing a wall section

Fig.3

Before starting work, it is necessary to free the supporting wall structure from the plaster layer along the drawn line so that the masonry seams are visible. However, it is necessary to remove the plaster with extreme caution, because most likely, there is wiring under it - damage can lead to the failure of the entire power supply system.

When the seams in place of the future empty space are visible, you can get to work. It is necessary to start removing bricks from the very top. First, the top row of bricks is removed, which will be the width of the entire door space.. A jumper is inserted here, on which the structure will be held.

Further, more holes are made above the jumper. In the resulting hole, it is necessary to mount a beam, which will act as a support. The support beam must be supported with a jack so that the structure does not collapse during operation. The beam and jack will support the weight of the entire wall structure (Fig. 3).

Jumper from the channel

Then all holes are smeared with a concrete solution. After drying concrete mix, you can continue to work on knocking out bricks.

The structure should be strengthened if the width of the door space is more than one meter.

To protect the floor from falling bricks, it is necessary to make flooring from boards. Bricks should be removed with diamond drills to minimize damage to the wall structure.

Violation of brick removal technology can lead to weakening of the structure, its premature wear and deformation.

It should be noted that the space under the door must be made 10-20 centimeters larger than the door or window frame. This gap can be filled with mounting foam.

Strengthening the opening

Strengthening works take the maximum amount of time, as they are painstakingly carried out. The organized empty space under the door or arch must be reinforced with channels. It is advisable to use a channel jumper with vertical posts. Channels are mounted on both sides, which are screwed into the previously installed wooden jumper with the help of bolts (Fig. 4).

If the space in the wall structure has a large width, then it is reinforced not only in the upper part, but also on the sides (Fig. 5).

How to determine the load-bearing wall in a brick house?

The most elementary way to determine the supporting wall is to familiarize yourself with the floor plan of the dwelling. Such a plan is necessarily available in the data sheet or house book. To understand the diagrams and drawings, you need to have little drawing skills. Experience in construction would not be superfluous. Then you can easily distinguish a supporting wall from a regular partition.

Rice. 6

Usually interior walls have a thickness of not more than 18 centimeters. The smallest thickness of the supporting wall is 38 centimeters - three-brick masonry. A four-brick masonry is possible, which forms a wall 51 centimeters thick. Often the thickness of the walls in brick houses is 64 centimeters - a five-brick masonry (Fig. 6).

If the plan could not be found, then you should use general rules definition of load-bearing walls in the house:

if the walls face the street, we can definitely say that they are supportive;
walls shared with neighbors;
the wall thickness is more than 380 mm, as mentioned earlier;
walls leading to the landing.

Exterior finish

After completing work on the formation of an opening in a brick load-bearing wall, everything must be decoratively finished (Fig. 7). What is needed for this? First of all, you need to make a choice finishing material. Will it be wood, plastic or decorative rock- you decide. Next, you need to show a little imagination and create decorating elements in the formed space. brick wall.

Rice. 7

For self-cladding, you should have basic knowledge in the field finishing works and a special tool is required.

If you need to arrange the space under the door without its presence, then you should use additional boards. It will add elegance to your new room decor and add sophistication to the interior. You can create such a lining yourself.

The opening, made in the form of an arch, looks beautiful. As a rule, arches are round or lancet. To determine the shape of the arch for the client, check out the design catalogs. The most common today is the Byzantine and Greek style. In some cases, the arch can be made backlit.

They decide to reschedule. This method will allow you to rationally use the territory of your apartment. However, often redevelopment also affects load-bearing walls. How to be in such a situation? Can a load bearing wall be demolished? Or, is it possible to make an opening in a load-bearing wall? We will consider the features of load-bearing walls, as well as cases when an opening can be made in them.

Is it possible to demolish a load-bearing wall?

The stability of the house is achieved due to the presence of load-bearing walls, which are made of heavy-duty material. If one of the walls is not removed, then the strength of the entire structure will be at risk. Due to the demolition of the wall, engineering calculations will be violated. Conclusion: it is impossible to completely remove the load-bearing wall, this is fraught with big troubles. It is quite another thing to make an opening in a load-bearing wall. This is allowed under certain circumstances. But for this, it will be necessary to first agree on the issue of redevelopment with the relevant authorities, carefully make calculations.

Features of load-bearing walls

The thing is that the load-bearing wall is subjected to heavy loads. Therefore, how strong it will be depends on the life of the whole house.

Not in all cases it is possible to obtain permission to make an opening in a load-bearing wall! This is due to the fact that the design of houses in all cases can be different. It is especially problematic to obtain such permission if you live on the first or second floor. In these places, the walls are under special stress.

Some take the wrong position on this issue. They make a hole in the wall, and then in fact apply to the authorities that they supposedly did not know or forgot to apply. But such people should be aware of the following. According to the latest regulations, unauthorized opening in a load-bearing wall can lead to heavy fines, and in the worst case, deprivation of the right to live in this apartment. But this is the maximum that you can run into. At least in this case, they will force the wall to be restored. Even if you managed to hide the fact of redevelopment, sooner or later they will find out about it.

If you live in a brick house, then getting permission to make an opening in a load-bearing wall is easier.

So, in order to get the coveted permission, you will need to collect the following documentation:

Floor plan of the apartment.
Remodeling sketch.
Apartment ownership certificate.
Filling out an application in a strictly prescribed form.

If you still get permission, you can get to work.

Opening manufacturing methods and necessary tools

As for the manufacture of the opening, many will think of a jackhammer. But such a view is erroneous. Although this method has been tested by time, it is not effective in all cases. Moreover, the use of a jackhammer to make an opening in a load-bearing wall has a number of disadvantages:

A large number of microcracks appear.
The integrity of the wall is violated, especially if it is made of brick.
The made opening must be further processed, which will entail additional costs.
In the process of work, a lot of noise and dust arises (secretly, you can’t do it in any way).
Many walls have metal reinforcement, which will make it difficult to work.

Today there are a number modern technologies, which allow you to quickly and with minimal labor to make an opening in the load-bearing wall.

Use of rope equipment. In this case, special bushings and a rope are used, on which artificial diamonds are installed. This method is effective for the reason that when it is used, dust, vibration, and noise are not generated.
Diamond drilling. Here, special diamond-coated drills are used. They can drill even holes around the entire contour of the opening. Accordingly, this method will save your costs for the subsequent processing of the walls. The use of diamond drilling allows you to maintain the integrity of the wall, both brick and reinforced concrete.
Saws with a diamond dusting. The best way if you want to find the best option making an opening in a load-bearing wall. There are two cutting methods: stationary and manual. The choice will depend on the size of the opening and the required quality.

Break not build!

To begin with, it is necessary to carry out a series preparatory processes. A jumper is pre-made, which will take on the entire main load from the wall above. This element is very important: the safety of the entire structure and yours, respectively, will directly depend on its strength. In this case, the following must be taken into account:

wall thickness,
the ratio of the size of the wall and the opening,
technical condition of the wall,
the material the walls are made of
distance to adjacent walls and ceiling,
the location of the floor slabs,
the number of floors above your apartment.

In the event that the opening will be made in a large wall, the floor slabs should first be supported. For example, props can be made from pipes or logs.

As for the material for the jumper, steel would be ideal. It is the most reliable and strong material for this purpose. As a rule, you can purchase a channel that is bolted on both sides or an I-beam. If you opted for installing a channel, then M20 bolts are suitable for connecting it. The distance between them should be half a meter. The length of the jumper must be sufficient so that it does not bend under heavy loads.

Now let's start making the opening. To begin with, the plaster is removed from the wall. To do this, you can first draw the outlines of the opening with chalk. Then an opening is cut for mounting the jumper. These strobes are made from two sides. Next, you need to drill holes for fastening the jumpers with bolts. These niches must be well cleaned so that a channel can be easily installed in them. Dust should be removed by wetting the wall with water.

After making the strobe, prepare cement mortar from cement brand M500. The solution should be dense and thick. It should be laid in the manufactured strobe, and then, install the channel and tighten it with bolts. Now the whole structure should solidify well.

In the process of work, voids may form. How to eliminate them? To do this, you can take small pieces of a block / brick, which are installed on the same solution.

Bolted connections must necessarily have washers!

After that, you can proceed directly to punching the opening. In this case, you can use any of the above methods. It should be noted that the punching of the opening must be done gradually. Think about how you will dispose of the resulting garbage and what size waste should be.

After making the opening, the slopes should be finished. In some cases, it is possible to make a reinforcement of the structure, especially if the opening has a large thickness. For this, it is mounted in the corners metal corner, which can be welded to the jumper. These corners are also welded together with metal plates. It remains only to plaster the slopes and proceed to the finishing.

There is another method for making a jumper from reinforced concrete beam. In terms of its strength, it is in no way inferior to the above technology. To install it, you must first make a through opening for the entire length of the reinforced concrete beam. She, in turn, is laid on cement mortar. It is possible to break through the opening only when the cement with the beam has seized. The subsequent process is the same as above.

If you want to use non-standard solutions according to the interior design of the room, during redevelopment, it is possible to make an arched opening in the load-bearing wall. But in this case, you will need to make a special design. To make such an opening, you will need to first prepare a profile or other material that will exactly repeat the outlines of the opening. Fastening is carried out according to the same principle. The only difference is that the structure as a beam should be bolted not only to each other, but also to the wall.

Before punching a hole in a load-bearing wall, weigh the pros and cons. Remember that you must first obtain the appropriate permission.

Detailed instructions for making an opening in a load-bearing wall:

Panel or brick house allows you to improve the layout standard apartment, for example, combine a kitchen with a room, or make a doorway between rooms more convenient location(and lay the old, inconveniently located).

However, it must be taken into account that the new doorway in the load-bearing wall not only makes the apartment more comfortable, but also implies a certain responsibility. This means that the owner of the apartment must comply with the redevelopment, as well as those affecting this area.

Coordination of the opening in the load-bearing wall

In order for redevelopment with an opening in the load-bearing wall to be legal and safe, it should be done, and we recommend that you take care of this before starting work - this way you will avoid a lot of trouble with supervisory authorities, as well as unforeseen costs for eliminating unauthorized changes. Moreover, the consequences of illegal redevelopment can be very serious. Since we are talking about a load-bearing wall, unskilled intervention can damage both it and adjacent structures, and lead to a decrease in their design bearing capacity, and sometimes to partial collapse. We are not talking about cases when the load-bearing wall is completely dismantled: this is an extremely dangerous and irresponsible step!

Decree of the Government of Moscow No. 508, as amended 840, in part of paragraph 2.2.4 of Appendix 1, classifies the punching of openings in load-bearing walls as an activity that requires the development of design documentation and technical opinion about the possibility of redevelopment.

Acceptance of openings in load-bearing walls by the commission

It is important to remember that work to strengthen the opening with metal structures is subject to delivery and is accompanied by registration, as well as registration. Without providing these documents to the Moscow Housing Inspectorate at the end of the repair, the acceptance committee will not sign, and it will not be removed from the control of the inspection until you provide the acts. Moreover, the owner may be required to remove the finish to check the metal reinforcement of the opening in the load-bearing wall for compliance with the approved project and current rules.

Only certified contractors with SRO approval in construction have the right to draw up acts of hidden work.

Examples of redevelopment projects with an opening in the load-bearing wall

1. This redevelopment was carried out in the house of the series, built before 2007, so the State Unitary Enterprise MNIITEP "gave the go-ahead" to the installation of an opening in the load-bearing wall between the kitchen and the room. The width of the opening is standard 90 cm.

2. A redevelopment project with an opening in the bearing wall and reinforcement with metal profiles, which were a U-shaped frame of channels. Such a powerful reinforcement was due to the significant thickness of the wall of the block house of the series.
