General contracting

Entrusting the entire building process to one entity, which is responsible for all the work and the supply of all the materials, is what general contracting is all about. Implementation will require the participation of numerous material suppliers, subcontractors, consultants and specialists, but we are responsible for everything, as a general contractor.

 

All the work that needs to be done (related to the investment) are detailed in the contract. Beginning with the investor’s expectations with regard to the construction of the building, to the technology used to complete it, and ending with the general contractor’s commitment to punctuality and responsibility. We carry out investments all over the country. Each of them is carried out in cooperation with local and experienced subcontractors, who carefully control and take care of the high quality of the work performed at every step.

 

Comprehensiveness and time-saving are some of the most desirable factors nowadays, which is why the decision to commission a general contractor will certainly satisfy many investors.

Earthworks

Shoveling – symbolic start of construction.


Geotechnical investigations – these determine the structure of the subsoil and calculate its bearing capacity.


Earth mass balance – a calculation that determines how much soil will need to be taken out of the project area to lower the level, or how much will need to be brought in to raise the level.


Macro levelling – the process of levelling the ground over large areas to ensure an even foundation level, essential for large-scale structures.


Soil replacement – necessary when the soil turns out to be biologically or chemically contaminated or
when its layers do not allow the safe foundation of the building.


Retaining walls – structures that protect the ground from subsidence where there is a large level difference.

Construction

After completing the earthworks and preparing the ground, the erection of the structure begins.

 

Foundations – underground structural elements on which columns and walls are erected, made almost exclusively of reinforced concrete.


Reinforced concrete – composite of concrete and steel reinforcing bars.


Optimization – static calculations that allow you to select the best-suited steel profiles or dimensions of reinforced concrete elements.


Prefabrication – the process of making structural elements, concrete or steel, off-site, which allows for shorter lead times and increased quality control.


Wreath – the completion of the erection stage of the structure is celebrated by hanging a wreath on the highest element of the building.

Housing

After erection of part or all of the structure, which is the skeleton of the building, the cladding of the walls, roofing and insertion of doors, windows and skylights begins.

 

The thermal insulation properties of the chosen materials affect how energy-efficient the building will be.

 

Layered panels – ready-made facade elements with a polyurethane or wool foam core, covered on both sides with sheet metal, used as wall cladding elements.

Skylights and smoke dampers.

Window and door joinery.

Building shell closed – completion of cladding and sealing of the building.

Installations

After reaching the closed shell state, the assembly of sanitary and electrical installations begins. The proper selection and implementation of the installations has a significant impact on operating costs, especially energy consumption.

 

Sanitary installations: heating – the heat source for the building can be natural gas, LPG gas, heat pumps or electric power, the heat can be distributed by radiators, heaters, radiant heaters or underfloor heating.

 

Sanitary installations: ventilation – the source of fresh air can be mechanical ventilation, additionally equipped with an air-conditioning system or heat recuperation to reduce heating costs.

 

Sanitary installations: domestic water, sanitary sewage system and stormwater drainage.

 

Fire protection installations – providing safety in terms of fire protection, which include Voice Alarm System, Fire Alarm System, sprinklers, smoke extraction, gas extinguishing. Electrical installations – providing lighting and power. Low-current installations – which are surveillance and control elements rather than power supply, and include BMS (Building Management System), CCTV (Closed Circuit TV), Burglary and assault alarm system.

Interiors

The final stage of work in the building is interior finishing, based on the interior design. Each element is defined in detail, presented in the form of visualization. Materials, their textures and colours are agreed at this stage to ensure a composition that is consistent with the client’s expectations.


Ceilings can be finished with plasterwork or enclosed with a suspended modular ceiling. Walls can be plastered and painted, enclosed with wall panels, covered with wallpaper or ceramic tiles. Floors can be finished with a finishing layer such as parquet, carpet, plastic flooring, ceramic tiles or left as a concrete floor.

 

The interior design includes built-in furniture, made to order and completed on site.

Land development

Ground hardening – access to the building must be hardened, on a suitable surface finished with concrete, asphalt, concrete blocks or stone.


Fences – Robert Frost wrote “good fences make good neighbours”, what means – good fences ensure good neighbours.


Greenery – lawns and planting must be done at the right time of year, with irrigation and safeguards that will allow the plants to survive for years after construction.


Landscaping elements – complementary equipment for outdoor areas such as benches, playgrounds, garden gazebos and others.

Handover of the building

Completion of the construction work is confirmed by acceptance protocols in which the participants confirm the conformity of the implementation with the project.

 

Depending on the type of facility, before it is allowed to be used, it is accepted by representatives of e.g. the fire department and the health department.

 

After acceptance by the specialist services, the District Building Inspector issues an occupancy permit. This is the “moment of handing over the keys”.
