Upon the investor’s request, the design of the facility is carried out. The production of the project plan consists of modular units of various widths, with the most common dimensions being 120cm wide. We strive for the designed facilities to comply with all applicable regulations and ecological standards, providing comfort and functionality. The advantages of modular buildings compared to traditionally constructed ones are as follows:

  • Environmentally healthy homes: the primary building material is wood, which, due to its structure, color, and scent, is considered the healthiest construction material.
  • Known fixed price at contract signing.
  • Greater earthquake resistance: capable of withstanding ground movement up to 10 degrees on the Richter scale. Wood, as a building material, is more elastic than brick, block, or concrete.
  • Better space utilization: walls are thinner than traditional ones, increasing window space utilization.
  • Fire resistance: Fire resistance rating F-60min (IMS Belgrade). The gypsum boards covering the interior walls and ceilings of our houses are non-flammable.
  • Better thermal insulation: Good thermal insulation of our buildings enables up to 40% energy savings per season.
  • Better sound insulation: Mineral wool, which is a component of external and internal walls, besides its thermal properties, is also one of the best materials for sound insulation.
  • Affordable price: Up to 40% savings compared to traditional solid construction. If we talk about the same thermal insulation properties, the price is up to 2.5 times lower.
  • Fast construction: Since all modular elements are manufactured in our production facility, the actual construction time and time required for assembly of these finished elements are 4-7 days depending on the size of the facility. Construction under the “turnkey” system, from ordering to occupancy, does not exceed 60 days, or 30 days when it comes to construction under the “gray phase” system.

 

After clearing the site and removing the topsoil layer, the facility is marked at the specified location, after which trenches are dug for the foundation beams. The foundation strips are founded at the depth provided by the project. They are made of machine concrete, below which a layer of compacted gravel or crushed stone is placed. The plinth walls are built over the foundation beams in double wooden formwork. The thickness of the walls is 20-25 cm, depending on the site conditions, and the height is 45 cm from the sidewalk level. Reinforced concrete belts are made above the plinth beams. Between the plinth walls, earth is filled and compacted in layers to the required height, over which a layer of gravel is placed to serve as a base for the concrete floor slab. The concrete slab is made of compacted concrete, about 10 cm thick. Over the plinth walls and the floor (first) slab, a waterproofing is applied using hot bitumen coating and condor in 2+1 layers, in two phases. In the first phase (before the assembly of the facility), waterproofing is done in strips 25-30 cm wide below the foundations, and in the second phase (after the assembly of the facility) on the remaining surface.

 

OTHER CONSTRUCTION WORK

The facility is designed to have one single-channel chimney with a cross-section of 16 cm. It is built from prefabricated schiedel elements and finished with a prefabricated concrete cap. Masonry is carried out after the first phase of facility assembly. The chimney is equipped with a cleaning revision and a connection for a stove.

 

WALL ELEMENTS

Wall elements are usually made in modular dimensions of 120×260 and 60×260 cm, or according to other dimensions specified in the project plan. The elements are produced in the workshop according to the main project and delivered to the construction site. The elements can be external and internal, solid or with integrated windows and doors depending on their location within the facility. The element structure is a wooden frame d=100 mm, made of healthy pine wood. Verticals (intermediates) in the panel are placed at 40 cm intervals. All elements have double-sided cladding with OSB panels d=10 mm. Mineral wool is placed between the claddings or in the wooden frame, serving as thermal and sound insulation. External elements incorporate mineral wool d= 100mm, while internal elements incorporate d= 80 mm. Wall elements are assembled and joined into one unit using foundation strips d=100/140mm, window sills d=100/42mm, and wooden strips inserted into pre-made grooves. Foundation strips are pre-coated with bitumen and anchored to concrete walls.

After the assembly of the facility, the facade walls are covered with ‘izoterm’ cladding 80-120 mm thick, while internal walls are covered with gypsum board panels d=12.5 mm. Elements for sanitary rooms are covered with waterproof gypsum board panels d=12.5 mm. During the element production, flexible plastic pipes and junction boxes for distribution installations are installed.

CARPENTRY

Joinery is made of six-chamber PVC profiles. The selection and sizing of openings are made according to the requirements of the rooms where they are installed. The construction of windows and doors is designed to be integrated into the wall elements during their production in the workshop or on-site after the assembly of the elements.

Windows and balcony doors are double, two-part, with tilt-and-turn opening around the vertical and horizontal axes using edge locks. Joinery is glazed with triple thermal insulation glass filled with argon 4+12+4 mm. Aluminum sills in the color of the joinery are installed on the exterior side. Entrance doors are 95/225 cm single-leaf partially glazed, without transom, with a combination division made of PVC profiles, equipped with a security lock. Internal doors are double-leafed 90/205, 80/205 and 70/205 cm. Entrance doors are secured with a security lock with a cylinder, while other doors have ordinary locks.

 

ROOF ELEMENTS

The roof structure is made of truss roof beams. Roof beams are made in a truss system with two-part belts and one-part or three-part infill rods, with connections made by nails in the zone of belts. Roof beams are made in the workshop from dried healthy pine wood class I/II according to the static calculation. The beams are mounted over the wall construction on modular supports (up to 120 cm) and anchored using metal “U” profiles. Roof beams are interconnected with plank sheathing d=24 mm in roof planes and vertical bracing, achieving spatial stability of the roof and the facility. Over the plank sheathing, a breathable membrane is installed, along with longitudinal and transverse battens 30/48 mm to provide ventilation under the roof covering. Roof covering is done with interlocking tiles. The roof edges are finished with OSB panels d=15mm, attached to a wooden frame. Roof ridges are finished with processed boards. The areas under the roof beams are covered with aluminum siding or facade material similar to external walls. All roof structure connections are made with appropriate nails.

 

CEILING CONSTRUCTION

The ceiling construction consists of joists, insulation material, and ceiling cladding. A grill of CD profiles is placed over the lower belts of the roof beams, followed by a vapor barrier of PVC foil and ceiling cladding.

Over the grill and ceiling cladding, thermal insulation of mineral wool d=100-200mm is installed. Ceiling cladding is made of gypsum board panels d=12.5 mm with the following composition:
