The design and construction of a new structure is only part of its life cycle. Owners often overlook the need for urgent structural repairs during the operation of old buildings. Structural and fortification repairs aim to:

  • remove dangerous defects in the building
  • increase the level of security of the structure by strengthening it
  • allow changes in distribution, change of purpose, complete reconstruction, new door and window openings

The ultimate goal is for the old building to meet the future requirements for it or to keep its original performance.

Aging of materials, subsidence, improper operation, design and execution errors, exposure to aggressive agents (such as salts in the soil and polluted air) are some of the causes of structural and cladding damage. Improper intervention and improper removal of defects pose risks and can lead to more expensive re-repairs and / or serious material and physical damage.

The Renovate team offers a wide range of activities covering the reinforcement, restoration and reconstruction of existing building structures and elements.
The guarantee for quality and price is achieved through the wide range of amplifiers
systems that we can offer to our customers. The specifics of each reconstruction site require an individual approach in search of the optimal solution based on the specific requirements set by the client.


Development of a constructive project for reconstruction or reconstruction

For the preparation of a constructive project for reconstruction, a preliminary complete or partial inspection of the building is required. Analysis of the survey shows technical and condition. The data from the survey serve for a thorough technical and economic analysis with a comparison between the possible options. For the selected variant a technical assignment is prepared with a proposal for restoration, repair, reinforcement, partial or general reconstruction.

Cost-effectiveness analysis

At the heart of any successful construction project for reconstruction is a well-prepared technical and economic analysis. It should reflect problems such as the cost of the repair, the durability of the result obtained, reliability, the possibility of future changes in purpose, time for the repair and economic factors related to it. In the technical and economic analysis a choice is made between different amplification systems in order to optimally achieve the results sought by the customer. It includes various alternative solutions and comparison between them in order to optimally meet the criteria set by the investor for the final result.

The requirements for the people who prepare a construction feasibility study are a good knowledge of construction technologies, organizational links between construction processes and common difficulties in the implementation of the project itself.

Аddition of new floor or space expansion

It is often the case that owners of older buildings would lean towards reconstruction with the thought of maximising the usage of the built-up area. The absorption of the attic space and its transformation into a living area is easily to do and is common for urban areas. Thus with minimal investment, we receive additional living space for personal use or rental. Another increasingly common approach is the upgrading of old buildings when property parameters allow it. Authorization and construction procedures, as well as construction itself, have various advantages as opposed to the complete demolition and disposal of the building and then erecting it again from scratch.

Reconstructions and repairs involving changes/amendments in the building structure

This is necessary when expanding, joining two floors with an internal staircase, opening for new doors and windows, integrating a balcony, changing the purpose, replacing existing floorings with high-tech and others. In building practice, there are countless examples of successful renovations, turning old, abandoned houses into works of architectural art.

Professional consultation about defects in a building that you inhabit or have investment intentions

Neglectment and cosmetic „repair“ of defects in the construction of a building poses real risks, especially in areas with high seismic activity, which include the territory of Bulgaria. In 1928. a series of three destructive earthquakes, the strongest (the second) with a magnitude of 7.0, are realized along the Maritsa River valley. The events caused considerable destruction in the cities of Plovdiv, Chirpan and Parvomay. It destroyed completely 74,000 buildings, about 150 people are killed and over 1,000 injured. The next strong earthquake was on 04.03.1977. In the Vrancea region (Romania) with M = 7.2. To date, in view of the 2-4 floor old masonry buildings, the age and their worst condition, increased population, a similar magnitude would result in much more severe property damage and a number of casualties.

In case of repair or complete replacement of the roof structure

The architectural solutions for the transformation of a loft area are countless.Just a few clicks on the internet search engine are enough to convince us that the room, which has been such an unnecessary warehouse area for old items, can become a perfect place to live or relax from the busy everyday life. In a number of aesthetic and economic reasons, the preservation of the original roof structure, built of old, massive beams, is a widely preferred choice among owners. The old roof, however, besides a remnant, also hides weak spots. Its repair is not exhausted by the possible replacement of the waterproofing and the cladding.

A prerequisite for the transformation of the roof space is the preliminary consultation with a engineer who will make a thorough view of the main roof structure. Particularly vulnerable places are the connections between the elements and the beams, wetted regularly over the years. Quality repairs ensure long-lasting security and comfort for occupants – something extremely important when talking about one of the weakest places in a house – the roof.

New door and window openings

In recent years, people’s lives have changed at an exceptional rate. Massive new appliances, different furniture schemes, modern architectural solutions are entering. All this must fit into our old houses built in a past era. The small windows in the old houses, the lack of a direct connection between the premises or the yard decrease the ergonomics of our home. Luckily a reconstruction involving new opening of light spaces for a door or window is quite possible in most cases(even in cases where the hole/gap is in a brick or reinforced concrete wall of the building). This, of course, can only be executed with an approved design by a civil engineer with experience in reconstruction repairs and well acquainted with the different types of work necessary for the reinforcement of the concrete and the masonry structures.
