"Building with administrative address Haskovo, ul. "Prolet" No. 12".
The examined building, located at ul. "Prolet" No. 12, in plot 77195.737.139 according to the cadastral map of Haskovo, was built in 1978. The building has only one entrance, which contains five above-ground floors and an attic floor, with no basement. It is built with a monolithic reinforced concrete load-bearing structure, consisting of columns, slabs, and beams.
The entrance of the building is from the south; vertical communication is through a naturally lit double-flight reinforced concrete staircase centrally located in the northern part of the building. Open terraces are constructed at the intermediate landing sites.
On the first above-ground (ground) floor, there are 6 garages in the southern part and 8 storage rooms (basements) of the owners in the northern part. The next four floors are residential, with two apartments located on each of them – a total of 8 apartments in the building. At the attic floor, there are 12 attic rooms. All the walls are made of brick masonry, with the facade bearing walls measuring 25cm in thickness, and the internal partition walls in the apartments measuring 25cm and 12cm.
The roof is gabled, with a cold type, having a reinforced concrete load-bearing structure - beam slabs with a 14% slope on the slopes. The roofing is of two types – the old coating is made of asbestos-cement wavy sheets, while the new one is made of profiled LT sheet metal. The roof's drainage is external – a system of gutters, water collection tanks, and downpipes running along the facades, most of which are directed into the building's embedded sewerage. All terraces are drained with pipes that discharge into adjacent vertical downspouts.
Some of the open terraces on the residential building's northern facade have been glazed – some with PVC joinery and others with metal – welding. The facade joinery of half of the apartments has been replaced with PVC, while the remaining apartments retain their old wooden joinery. All facade joinery, regardless of type, has aged, does not meet modern regulatory requirements, and needs replacement. On the walls of the western facade of the last two residential floors, thermal insulation is applied, but with a small thickness and indicators that do not comply with the applicable regulatory requirements for thermal transfer and energy savings.
The entrance of the building is from the south and is at the level of the adjacent sidewalk, ensuring accessibility for people with mobility disabilities. Vertical communication within the building is maintained via a double-flight staircase – from the ground to the attic floor. There is no elevator in the building.

“Building with administrative address Haskovo city, 69-71 Stara Planina St.”.
The surveyed building, located at "Stara Planina" Street No. 69-71, Haskovo, was constructed and put into operation in 1977, intended for residential use. It was built using the PPP system (precast concrete plates). It consists of two separate sections with a joined building on the seam. The two sections, together two residential entrances, are ten stories high, with eight residential floors, one ground (garage) floor, and one attic floor, with designated staircases providing access to the residential floors. The sections are designed with elevator shafts. Roof access is via dormers from the last (attic) floor.
The roof of the building is flat with a reinforced concrete slab. Water drainage is internal via funnels. The roof of the attic rooms is of the "warm" type. The facades of the building are made of brick masonry - 25 cm and fine spray plaster, with a bush-hammered base. The staircase is double-sided, constructed from prefabricated elements - stair treads and landings.
Each section has one entrance (total 2), and each entrance has 3 apartments per floor. Access to the residential entrances is from the north. Parking spaces are designated in front and there are green areas to the east and south.
The railings of the balconies and loggias have ornate details made of metal and concrete elements according to the original project, but a large part of them have been enclosed and bricked up. The total height of the parapets is 105cm, while the height from the finished floor of the terraces is 90cm.
During operation, partial repair activities have been carried out on the façades with thermal insulation and plaster application. The ground floor acts as a base and is finished with rough grey plaster.
The windows when the building was put into operation were white wooden framed with single white glass. Currently, some apartments have replaced the windows with white or wood-patterned PVC/Aluminum frames with double glazing.
The building has been partially facaded with thermal insulation and repainted, with glazed balconies and loggias with PVC and aluminum frames and single metal frames. Many of the balconies/loggias adjacent to kitchens have been enclosed and added to the kitchen area. In some places, the original wooden frames with single glass have been retained. All unrenovated windows and doors of the building are in poor condition and have a high coefficient of heat transfer.
The roof above the attic rooms is of the "warm" type. Bitumen waterproofing has been laid above the last level, which has been replaced, but still has areas where integrity is compromised. The slope to the funnels is insufficient for draining rainwater, which leads to prolonged retention of water on the roof's surface and subsequent penetration into the apartments.
The roof edges are clad with galvanized sheet metal, which has corroded in places and has compromised joints. The chimneys are unmaintained, with crumbling plaster, lacking built caps, and the metal covers have corroded, displaced in places and allowing atmospheric waters to penetrate into the living spaces below.

The surveyed building, located in Haskovo, "St. St. Cyril and Methodius" No. 96-104, in PI 77195.706.270, was built in 1972 as a multifamily residential building. The building is 1-sectional with 3 entrances, each with a separate stairwell and elevator. The three stairwells are identical. Each stairwell has an elevator with the first stop on the ground floor and the last - on the 8th residential floor. On the attic level is located the machine room for each elevator. On each residential floor in entrance "A" there are one 3-room (southern) and two 2-room apartments. On each residential floor in entrance "B" two 4-room apartments are located. On each residential floor in entrance "B" there are three 2-room apartments. Each apartment has a bricked chimney in each room, and in the bathrooms and toilets - ventilation ducts. Each dwelling has one storage room on the ground and attic floors.
On the ground floor for each entrance, there is also a common room, particularly in entrance "B" where there used to be a boiler room when the building had central heating. The premises on this level have direct access to the adjacent ground level from the east - one for each entrance. On the intermediate platforms behind the elevator shafts are small rooms equipped with a sink for common use.
The balcony railings from the west are of two types: solid, made from brick masonry with a finished thickness (with plaster and putty) of 15cm and ornate, made from metal profiles (angle iron and "hollow square"). All balcony railings on the east are solid. The height of the balcony railings is 0.90m from the west and 1.00m from the east.
The main roof (above the attic level is of the "warm" type) - horizontal reinforced concrete slab with insulation made of perlite, reinforced cement screed, waterproofing from 3 layers (veil, konobit, veil) and protective coating from small river gravel. The roof has a reinforced concrete canopy around the perimeter, clad with galvanized sheet metal.

"Building with administrative address Haskovo, "Danube" St. No. 30".
The residential building was constructed around 1978 and has been in operation for over 44 years. The building continues to function as a multi-family residential structure, currently containing a total of 72 housing units (with 6 apartments per floor). An adjacent low utility building consists of a "boiler" part and a "hydrophor" part, meant to serve the residential building. The boiler has not functioned for years. By the meaning of item 29 (supplemented - SG, issue 16 from 2021), § 5 of the Additional provisions of the Spatial Planning Act (last amended and supplemented SG, issue 6 from January 20, 2023) - the building is defined as a "Residential building". By construction method, it is a package-lifted slabs construction system. Each dwelling contains the necessary residential and service premises, with each also having storage space (basement - at the cellar level and attic space at the attic level of the building).

The multi-family residential building has one entrance/exit, which is accessible via a wide reinforced concrete single-sided staircase containing 9 (nine) steps and through the rooftop terrace of the low utility building.

Two elevators are available in the building - a small one and a large one, with the dimensions of the large elevator allowing its use by wheelchair users.

A ramp has been built for the external staircase, a "slide" type, which is very steep, slippery, uneven, narrow, etc. - not meeting the regulatory requirements and practically preventing safe use by both people with disabilities and mothers with strollers.

To ensure accessible architectural environment to the entrance of the residential building, it is necessary for the existing concrete ramp to comply with the requirements of Regulation No. RD-02-20-2 of January 26, 2021, of the Ministry of Regional Development and Public Works for determining the requirements for accessibility and universal design of accessible environment elements in urbanized areas and buildings and facilities (published SG, issue 12 of February 12, 2021, last amended and supplemented SG, issue 20 of March 11, 2022).

The facade joinery is diverse in type, installed both during the construction of the building (wooden glued according to Bulgarian State Standard and metal), as well as partially replaced at different times depending on the owners' resources.

Main roof of the building: flat roof over unheated attic level and over machine rooms of elevators. The machine rooms extend above the level of the main roof. Access to the roof level is achieved via the inter-floor staircase and through a window at the top level. A low reinforced concrete roof edge has been built along the external contour of the building's roof, with a protective skirt made of galvanized sheet metal on the upper side, and along the inner part of the edge (towards the roof) - with protective flashing made of galvanized sheet metal. As of the current inspection period, the roof of the building is finished with protective felt covering placed during the construction over waterproofing.

The facade walls of the building are brick walls with a masonry thickness of 25 cm, with plaster applied on both sides. Along the outer line of some closed balconies/terraces, there is partially executed masonry from aerated concrete or brick, with plaster or tile putty applied, with or without subsequent finish coating. The floor slabs have corresponding coverings - on terraces/balconies - covering with mosaic or tiles, and their bottoms (ceilings of the open terraces) - smooth plaster. Around the perimeter of the building, from the level of the adjacent terrain to the bottom of the floor slab of the first residential floor, the visible part of the walls at the first basement level is finished with chiseled bush hammer - base of the building.

The multi-family residential building consists of two housing sections, each with an independent entrance, respectively "12A", "12B", totaling 42 apartments and 18 garages located at ground level.
The construction system is package-lifted slabs. The building is constructed with a mixed prefabricated-monolithic system with monolithic reinforced concrete foundations, basement walls and columns, monolithically connected and forming diaphragms with the slabs, monolithic stairwells, and floor slabs executed at ground level in a package stacked one over the other. Subsequently, the package was lifted using lifting installations, and the columns were installed. The columns are jointed with the slabs. The foundation is realized using monolithic reinforced concrete strip foundations. The vertical loads from their own weight and useful load are transmitted from the roof and floor slabs to the walls, columns, basement walls, foundations, and from there to the soil base. Horizontal loads are taken by the diaphragms around the stairwells. The stairwells are constructed before the installation process to ensure the horizontal stabilization of the structure during the assembly stage.

The entrance landings of the entrances are accessible through aluminum entrance doors. The doors to the basement are wooden.
Garages are accessible from ground level via metal double doors.
Each entrance is provided with vertical communication via double-wing staircases and a passenger elevator. The elevators in both entrances are operational. The stairwells in both entrances are located in the median axis of each of the sections. Access to the entrances is achieved via external steps, and from the entrances of each section, differential steps approach the residential floors. Access to the basement of the building, where the apartments' cellars and the common service rooms are located, is also provided from the same entrances. The basement consists of stairway arms, corridors without natural light, storage rooms, and a common room.

The roof is flat, cold type with an attic space that is ventilated through openings in the facade panels. The roof is accessible from the last floor of each entrance via a staircase and metal skylights. Drainage is provided by means of funnels channeled to the building's sewage system.

"Building with administrative address Haskovo, 5 Aida Street".
The multi-family residential building consists of one section with two entrances, freely located on the property. The separate entrances - entrance "A" and entrance "B" have an equal number of above-ground levels (floors) – one floor with basement spaces, nine floors with residential units, and one floor with attic spaces. There is no unused attic space in the building. The ground floor contains storage facilities (basements). The connection between the levels is provided by double-arm reinforced concrete stairs and passenger elevators. The entrances of the building with the staircase are located towards the west. On each of the floors, several residential units (apartments) are designated – one-bedroom, two-bedroom, or three-bedroom, with a separate kitchen. All residential units have outdoor spaces – balconies or loggias, some of which are partially or fully enclosed with various types of windows. The changes compared to the original design during the construction of the building, made in the process of operation, are reflected in the graphical part of the survey. The building is in good overall condition, corresponding to similar buildings constructed during the same period by a similar method. Typical materials, products, and details from the design and construction period were used in the execution.
Various types of windows are present in the building – wooden double-layered, glued (the original type used during the construction of the building), replaced in some places with aluminum or PVC, glazed with double-glazed panels. The enclosure (glazing) of balconies and loggias has been done in various ways, including with single-layer metal frames, PVC, or aluminum with double-glazed panels. Some of the PVC windows are new, of good quality and with high energy characteristics. The entrance doors in the building are metal. The graphic part of the survey indicates the type of external windows. With the chaotic and indiscriminate replacement of windows and the glazing of balconies and loggias on individual independent units, the authentic architectural appearance of the object has been lost. The condition of the metal, wooden, and some PVC and aluminum windows is poor.
The roofs over the attic spaces and over the staircase cells and elevator machine rooms are single slabs. The covering is a waterproof membrane based on bitumen with a protective sprinkle. The drainage of atmospheric water from the roof is internal, through roof water receivers (funnels) and downpipes. The condition of the roof insulations, sheet metal cladding, water receivers, hollera, plastering and caps on chimneys is poor.
The staircase cells have concrete mosaic flooring and stairs in relatively good condition. The handrail of the staircase is openwork, with metal vertical elements and a wooden handgrip of appropriate height. The walls are painted with water-dispersible paint, and at a height of about 1.50 m from the floor, a plinth is made with alkyd paint. No repairs have been made in the common areas recently, and they are relatively worn out, with no significant defects observed. The windows in the staircase cells are in poor condition.

The inspected building, located at ul. "Syedineniye" № 39, Haskovo, municipality of Haskovo, region of Haskovo, represents a 4-story multi-family residential building, monolithic construction with a reinforced concrete skeleton structure. The two stair cases serve two residential entrances, each with an exit to the north and south. The basement floor contains storage rooms. The building has an unused attic space. It was built and put into operation in 1960. In addition to four above-ground floors, there is one semi-basement. There are also non-residential units on the first and third floors – commercial, service and health consulting rooms.
The construction of the building is a monolithic reinforced concrete skeleton. All walls are made of dense ceramic bricks-single (25х12х6.5cm). As a result of a series of alterations, the majority of the first-floor area has acquired a different function than the predominant residential one. The structure and respectively the distributions in the two entrances of the building are mirror images. The structural (including the slab) height of the residential floors is 2.70m. All inter-floor slabs are reinforced concrete with an average thickness of 15cm with floor coverings. The clear height (from floor to ceiling) of the rooms is 2.55m (on average, depending on the type of flooring).
The staircases are monolithic reinforced concrete with direct natural lighting (windows on each intermediate platform). The stair railing is solid, made with masonry from dense ceramic bricks 12 cm and is 90 cm high. The flooring in the stair cells is monolithic mosaic. Both staircases lead to the attic space. The two parts – independent for each entrance are isolated from the stair cells by metal doors. The roof of the building is reinforced concrete with a 40% slope - made of reinforced concrete structure and ceramic tiles. The drainage is external with downpipes and streets. The downpipes are not connected to rainwater drainage. Roofing drainage is executed using galvanized sheet metal downpipes and hanging gutters.

"Building with administrative address Haskovo, ul. "Georgi Benkovski" №40-46".
The residential building, with an administrative address at "Georgi Benkovski" St. No.40-46, Haskovo, represents a multifamily residential structure built in 1989 as a prefabricated, reinforced concrete, frame-less, large panel construction, executed according to the standard project by KIPP "Glavproekt" for a construction system for large panel residential buildings (EPRB) BP-87-Gl-1. The building is located in UPI-II, quarter 207, Haskovo and consists of three entrances/sectors. The executed sectors are "322" for entrance "A", sector "312" for entrance "B" and "312" for entrance "C".
In 1995, a five-story annex was built on the southwest side of the building, adjacent to entrance "A". The structure of the annex features a monolithic, frame-beam design consisting of reinforced concrete foundations, slabs, beams, and plates. The enclosing and partition walls are brick and are non-load bearing.
Each floor of the annex consists of a single space, with the project anticipating the establishment of an entrance from the living rooms of the southwest apartments. A garage has been constructed at the basement level, accessible from the west. At the first floor of the annex, access from the living room has not been implemented, making this room unusable, while entrances have been established at floors 2, 3, 4, and 5.
The separate sections and the annex are divided by a deformation joint between them. The specified joint also serves as an earthquake-resistant joint.
Entrance "A" consists of 7 residential floors, a semi-buried basement level, unused attic space, and a machine room. The entrance door is oriented to the west. Vertical communication is performed through a two-flight reinforced concrete staircase and one elevator. Storage rooms (the apartments' basements and those for common use) are located in the semi-buried basement. Some of the corridors and basements have natural lighting via basement windows.
Entrance "B" consists of 8 residential floors, a semi-buried basement level, unused attic space, and a machine room. The entrance door is oriented to the west. Vertical communication is achieved by one two-flight reinforced concrete staircase and one elevator. Storage rooms are also present in the semi-buried basement, corresponding to the apartments and shared utility spaces. Some corridors and basements also have natural light via basement windows.
Entrance "C" consists of 24 apartments (8 studios, 8 one-bedroom, and 8 two-bedroom), with one of each apartment type located on each residential floor (a total of 3 apartments per floor).
On the intermediate landings and in the three entrances, one cleaning inventory room is provided, which on the ground floor is separated from the entrance to the respective section and has its own exit outside.
Over the years of operation, some apartments have undergone partial renovations and modifications – mainly glazing of terraces using a metal frame (angle steel) and individual plain glass or with PVC frames; partial closure of terraces using masonry from Ytong and PVC frames and in places – integration into the rooms.
At each entrance/section, the roof is of the "cold" type, with a ventilated attic space made of prefabricated roofing nomenclature elements. The finish is composed of roll bitumen waterproofing placed on a cement screed for inclination. In the zone of the cold roof, the facades are closed with cornice panels, some of which have openings for ventilating the unused attic space. The drainage of the roof is internal. The roofs over the machine rooms are at a higher level compared to the main roof of the building, with a single-pitched reinforced concrete roofing slab and external drainage. Access to the upper surface of the roof is via the machine room in each entrance, with access to the room from the last intermediate stair landing, using a metal ladder and through a metal solid cover. Access to the attic space is via an opening with a metal cover in the wall, using a portable ladder for access.
Flat roofs have been constructed over the entrance landings, also made of prefabricated reinforced concrete roofing elements – with waterproofing, plaster on their underside, and a pointed finish; the drainage is external, through spouts.
In places on the facades, an external thermal insulation system has been applied (executed over the years of operation by the owners of individual apartments). Some apartment owners have performed a foundation on some of the terraces with Ytong, finished outside with plaster, and inside – plaster and paint. Thermal insulation has been applied on the new masonry of certain terraces, with a finishing layer of mineral mortar.
No accessible environment has been provided for the building, according to REGULATION No. RD-02-20-2 from January 26, 2021, which aims to define requirements for accessibility and universal design of accessible environment elements in urbanized territories and buildings and facilities.
