The projected residential complex consists of five houses of 20-25 floors. Dimensions of the structure: 18.6 x 159.4 m, maximum height: 74 m. In the project of a 25-storey building, a basement is planned, in which there is a through passage along the entire complex. The first level includes apartments, as well as built-in premises for shops, an office center, a post office with independent exits to the street. The floor also has separate entrances to the residential part, concierge room, lobby. On the other levels there are apartments, including those with free planning. Communication in the building is provided by stairwells, elevators. Each residential module is equipped with exit pits and garbage bins.

Structural and space-planning solutions

The frame of the building is planned from monolithic reinforced concrete structures. External wall materials: monolithic reinforced concrete, solid brick. Finishing is made according to the ventilated facade system using porcelain stoneware. The plinth is lined with Putilov stone. The foundations are monolithic reinforced concrete slabs on pile foundation. Interior decoration There are no apartments in the project.

Ready-made design solutions presented on the Mosproekt website are being finalized taking into account the requirements of the customer. Together withdesign of multi-storey residential buildings , bureau specialists are also ready to offer:

— construction control;

— development of project documentation;

The elevator ride almost ended in tragedy in one of the residential complexes in the Leninsky district of the Moscow region. People descended from the 25th floor. At some point, a metal cable broke, breaking through the ceiling of the cabin, and the elevator suddenly flew down. The life of the passengers was saved by a safety mechanism. Moreover, according to the residents, this is not the first incident with lifts. TV channel report "Moscow-24".

Semyon Mashkov and his site neighbor Georgy Kurganov recall what they felt at the moment the elevator fell from a height of several floors.

"We entered the elevator on the 25th floor, went for a walk with the dog, pressed the button, the elevator started moving and after about 40 seconds there was a sharp bang. Then it was not clear what happened, then there was an acceleration, we sat down, the elevator was full of dust, the ceiling collapsed, and the chain fell through the ceiling," says Semyon Mashkov.

“Some one was shaking at first, just a second, then abruptly somehow everything was covered in dust. I managed to jump to the door, and then a minute later we saw what happened, what the consequences were, what collapsed, and this chain was just lying around,” — says Georgy Kurganov.

It turned out that the elevator had fallen between the first and second floors. The victims had to sit in a locked cabin for almost an hour. Failed to call the dispatcher.

"We heard the dispatcher, and feedback did not have. The concierge already called the engineers on the phone, after 40 minutes he came up," explains Semyon Mashkov.

Despite the fact that the house is new, it has been rented out a little more than a year back, with elevators here, according to the residents, a constant problem.

- It was presented as a house of increased comfort, as if elite - a brick, a monolith. Unfortunately, problems have been accompanying us since then, especially elevators - they are constantly breaking down.

All the same housing complex, the elevator in the building opposite. This summer, Anastasia Komarova and her 4-year-old daughter became hostages of the cargo compartment there. After what happened, the girl is still afraid to go down the elevator.

“We drove two floors, there was a terrible rattle, and the blow was very strong. So strong that our bike fell on its side, and we could hardly stand on our feet,” recalls Anastasia Komarova.

Residents of this entrance, after the fall of the elevator with Anastasia and her daughter, try to avoid traveling in this particular cabin. Those who live below the floors, and the house is 25-story, do try to go up and down on foot.

- We constantly make applications, but the reaction to them is not as fast as we would like. We want this to get better.

After another emergency with an elevator, Georgy and Semyon decided to write a statement to the police and intend to demand management company understand technical condition elevator facilities in the house.

I am preparing a similar request to the Ministry of Construction, if there is something to add, please:
Please inform us that there is no need to develop special technical conditions (STU) for the designed multi-apartment one-section residential building of the functional class fire hazard F1.3, degree of fire resistance I, functional fire hazard class C0, height (according to clause 3.1 of SP1.13130.2009) less than 75m, with total area apartments per floor less than 500m2. The exit from the floors is carried out in a non-smokeable stairwell of type H1. The building is equipped with appropriate systems fire protection according to SP 5.13130.2009; SP 3.13130.2009; SP 7.13130.2013; SP 10.13130.2009 and others. This building is designed as a 26-storey one.
The basis for this letter was the observation of the C-th examination, according to which, water consumption for buildings with a height higher and more than those indicated in the table should be accepted and agreed in the manner established by order No. 36 of the Ministry of Regional Development of 01.04.2008 according to paragraph 1.3, 5.2 SP 8.13130.2009; p.p. 1.1, 4.1.1 SP 10.13130.2009.
We consider this claim of the expert far-fetched and unfounded.
The reference to clause 1.3 of SP 8.13130.2009 was incorrectly provided by the expert, because to reach the required level fire safety of the designed building do not apply technical solutions different from the decisions provided for by the sets of rules, due to the absence of the need for this.
The reference to clause 5.2 of SP 8.13130.2009 was incorrectly given by the expert, since the water consumption for external fire extinguishing of the designed building is assumed to be the maximum value of 30l / s according to the next column of the corresponding row of table 2 of SP 8.13130.2009 (i.e. for a building of a larger building volume, which generally corresponds to the procedure determined by the explanations of the Federal State Budgetary Institution VNIIPO EMERCOM of Russia).
Previously, TRoTPB Art. 68 hours 7, the following procedure was established: Water consumption for external fire extinguishing of buildings, the height or volume of which is greater than the height or volume indicated in the table ... must be increased by at least 25%.
The height of the projected 26-storey building does not exceed the height of a similar type of 25-storey buildings - up to 75m, due to a decrease in height typical floor within the allowable value. The required water consumption for external fire extinguishing of buildings of the same height, but different number of storeys, from the point of view of hydraulics, remains unchanged.
Design solutions for water supply, incl. for fire-fighting needs, a 26-storey building was accepted on the basis of the Technical Specifications for connection to water supply networks, issued by the network organization of the water supply system, in compliance with the requirement of SP 31.13330.2012, clause 5.11: Minimum free pressure in the water supply network locality with a maximum domestic and drinking water consumption at the entrance to the building above the ground, it should be taken for a one-story building at least 10 m, with a larger number of storeys, 4 m should be added to each floor.
Missed by fire expert important nuance in reading this norm, namely, that in the notes to table 2 of SP 8.13130.2009 there is no regulatory requirement for the need for STU for buildings KFPO F1, F2, F3, F4, in contrast to notes 5 to tables 3 and 4 of SP 8.13130.2009 - for KFPO F5 buildings: “Water consumption for external fire extinguishing of buildings with volumes exceeding those indicated in tables 3 and 4 is subject to justification in special specifications". Legally, the extension to residential buildings of the requirements for the development of STUs of a clearly limited scope, which is valid only for industrial buildings and does not apply to residential buildings, is not lawful. The codes of practice (including SP 8.13130.2009) are the norms of direct direct action.
The reference to clause 1.1 of SP 10.13130.2009 was incorrectly provided by the expert, because to achieve the required level of fire safety of the designed building, technical solutions other than the solutions provided for by the codes of practice are not used, due to the lack of this need.
The reference to paragraph 4.1.1 of SP 10.13130.2009 was incorrectly provided by the expert, since the water consumption for internal fire extinguishing of the designed building is assumed to be 3x2.9l/s, which is higher than the maximum value of 3x2.5l/s according to Table 1 of SP 10.13130.2009. According to the clarifications of the Federal State Budgetary Institution VNIIPO EMERCOM of Russia, the number of jets indicated in tables 1 and 2 of SP 10.13130.2009 is intended for calculating the fire water supply pumping station and is not associated with the localization of a specific fire source. adopted by the project pumping station internal fire water supply, as well as the water supply scheme, pipeline diameters make it possible to supply a larger number of fire jets of the required flow rate than defined by SP 10.13130.2009.
The fire expert missed an important nuance in reading this norm, namely, that in the notes to table 1 of SP 10.13130.2009 there is no regulatory requirement for the need for STU for buildings KFPO F1, F2, F3, F4, in contrast to notes 1; 2 to Table 2 of SP 10.13130.2009 - for KFPO F5 buildings: “1. The "-" sign indicates the need to develop STU to justify water consumption. 2. For buildings, the degree of fire resistance and the fire hazard category of which are not indicated together in the table, the development of STU is required to justify water consumption. Legally, the extension to residential buildings of the requirements for the development of STUs of a clearly limited scope, which is valid only for industrial buildings and does not apply to residential buildings, is not lawful. Codes of rules (including SP 8.13130.2009) are norms of direct direct action.
Previously valid "fire regulations" SNiP 2.01.02.85; SNiP II-2-80 did not contain restrictions on the height or number of floors. In SNiP 2.08.01-85; SNiP 2.04.01-85; SNiP 2.04.02-84; SNiP 2.08.01-89 * contained provisions that these rules and regulations apply to the design of residential buildings up to 25 floors inclusive. With subsequent changes regulatory framework, the conceptual criteria (dimensions) of the height of buildings (from the number of floors to the size in meters) were changed to determine the limitation of the effect of the relevant ND on the designed buildings. According to the current currently the procedure established by SP 4.13130.2013 clause 1.2; SNiP 21-01-97* clause 1.5; SP 54.13330.2012 p. 1.1; also updated SNiP 2.04.01-85 SP 30.13330.2012 p. 1.1, etc., STUs should be developed for residential buildings with a height of more than 75 m (and not more than 25 floors), respectively, the rationale for design decisions for external and internal fire extinguishing should be developed for residential buildings with a height of more than 75m must also be justified in the STU.
Requirements for outdoor and indoor fire water supply(discussed tables and notes to them) were not included in the updated editions of SNiP 2.04.01-85; SNiP 2.04.02-84: SP 30.13330.2012 and SP 31.13330.2012, respectively.
With respect to SNiP 2.04.01-85; SNiP 2.04.02-84 were previously published (“Rationing, standardization and certification in construction”, N 6, 2003) clarifications of the technical regulation department of the GOSSTROY of the Russian Federation, including: “It should be borne in mind that the requirements of these documents are based on provisions of SNiP II-2-80 " Fire regulations design of buildings and structures. ... In connection with the introduction from 01.01.1998. SNiP 21-01-97 * and a new classification .... ".
SP 8.13130.2009 and SP 10.13130.2009 were developed by FGU VNIIPO EMERCOM of Russia and approved by orders of the EMERCOM of Russia. Majority regulatory requirements SP 8.13130.2009 and SP 10.13130.2009 are borrowed from the old editions of SNiP 2.04.02-84 and SNiP 2.04.01-85, Table 1 of SP 10.13130.2009 completely duplicates Table 1 of SNiP 2.04.01-85, Table 2 of SP 8.20130. duplicates table 6 of SNiP 2.04.02-84 (with the exception of the note: Water consumption for external fire extinguishing of buildings with a height or volume exceeding those indicated in table 6 ... must be accepted and agreed in the prescribed manner), i.e. SP 8.13130.2009 and SP 10.13130.2009 also do not take into account the introduction of a new classification since 1998 according to the degree of fire resistance of buildings and structures. Accordingly, the specified tables of SP 8.13130.2009 and SP 10.13130.2009 have not been amended in relation to determining the height of buildings (from the number of floors to the size in meters), unlike all other current regulatory documents.
The illiterate requirements contained in normative documents, lead to their ambiguous interpretation, entail the need to execute excessive far-fetched costly decisions, are an additional administrative barrier for the business community, creating a corruption component in the activities of supervisory authorities. The rule-making activity of the EMERCOM of Russia causes certain criticism, incl. from the side of the first persons of the state: V.V. Putin: "... either the Ministry of Emergency Situations, then Rospotrebnadzor, then fire services, other structures ... introduce their new rules without coordination with the Ministry of Construction, and one can imagine the situation of investors, developers. In As a result, the entire design base of future construction projects simply falls apart: everything needs to be recalculated, redone, and additional funds must be spent, and, of course, time. This state of affairs, of course, needs to be changed and business-like, effective interdepartmental interaction must be built." http://www.kremlin.ru/events/president...
The link to order No. 36 of 04/01/2008 of the Ministry of Regional Development of the Russian Federation was not correctly provided by the expert, since this order was canceled by the Ministry of Construction of Russia at least twice, incl. Order No. 406 dated July 28, 2014 and Order No. 248 dated April 15, 2016.
Recently, the Ministry of Economic Development of the Russian Federation, the Ministry of Construction of Russia, and the department of Glavgosexpertiza subordinate to the Ministry of Construction have been actively working to eliminate cases of requirements for the development of STUs in the absence of such a need from the local examination authorities. Unfortunately, the leadership of the C-th examination is not able to figure out such a simple matter applicability of the norms, continues to profess a bureaucratic approach of refusals on formal grounds to make informed decisions.
