Renovate offers the services of a leading team of proven experts in the field of reconstruction, reinforcement and restoration of building structures. The team offers consulting and development of the necessary technical documentation at every stage of the construction investment process in new or existing buildings.

Pre-determination of the current condition

Based on the overall inspection of your building construction, the availability of the construction documentation you currently hold, will be analysed, which will be followed by a solution proposition in order to achieve the highest level of safety and the service life of the product. According to BNS (Bulgarian National Standards) EN 1998-3: 2005 there are three levels of information KL1, KL2 or KL3.). In the case of structural failure, its LS limit state of failure it determined according to BNS EN 1998-3 (before collapsing -NC, Significant Damage – SD and Damage Limitation – DL)

Territory examination

At this stage, the client instructs the designer by providing a territorial/land study which allows for clarity regarding the parameters of construction and other legal restrictions related to the construction project, if any. At his stage a preliminary assessment of compliance could be issued. . Next step is to make sure that the goals set by the client are intact with the actual legal boundaries for the particular site.

Legal advice

The specifics related to construction workon existing buildings requires a good grasp of the national regulations. Usually these type of activities affect foreign interests, which itself leads to court in the case of controversial disputes. Predeceding these difficulties at an early stage can prevent possible obstacles to a project.

The meaning of consultancy activities must be complied with the definition provided by the Statute. It involves an assessment of compliance with the Investment Project (IP) including essential requirements for the construction works within the sense given by Stature. Obtaining legal advicefrom practitioners with extensive knowledge in the field of construction law could be beneficial in many ways; e.g. safe execution of client`s intentions, early determination of problematic areas and last nut not least- costs. It is a mandatory requirement for those carrying out this activity to be entered on the licensed list of persons entitled to exercise construction with supervision. The final stage consists of an assessment of the IP(Investment Project) done in accordance with the appropriate Stature and includes the approval of the work design shortly followed by the issue of a construction permit.
Do not hesitate to contact us in case of any construction issues or procedures that may emerge,We could provide you with information regarding which legal services and legal entities you should turn to; we could advise further in case of appeals against legal instruments/statutes such as the “Regional directorate for national construction control” or anything relating to the regional municipal administration.

Preliminary / final economic evaluation

The results of the preliminary analysis can serve as an initial guide or as a final economic evaluation. It provides an insight as to what cost-effective investment of additional resources is, considering the final aim, which is reaching high standards of erformance for the building. In most cases those include achieving a high level of safety, extending service life, increasing the useful area or its loading, change of intended purpose.

Technical investigation

In some cases, more detailed investigation including architectural and technical examination of individual elements or of the entire construction is required. The aim is to reach the KL2 or KL3 information level according to BNS EN 1998-3: 2005, which will provide the necessary information about the condition and the possibilities of the construction. Based on this information, the design assessment and the construction work are included in the project . Based on the results of the technical investigation, it may be necessary to reproduce an economic assessment including additional construction activities.

Project assignment

In case of a positive result of the economic examination, the contracting authority shall prepare a project assignment. In case he is not well informed with construction work, the project assignment shall be prepared under the supervision of the designer or the external advisor. In it the project assignor defines the design phases (Concept Design, Developed Design, Technical Design), the parts of the project for each phase, depending on the type and the specificity of the site: the parameters of the construction and additional requirements. When assigning the parts of the project the requirements for mandatory minimum scope and content as required by Regulation No 4 of 21 May 2001 on the scope and content of investment projects.

Design visa

The design visa is issued according to the construction category in which the object belongs to. According to Ordinance No. 1 of 30 July 2003 on the Nomenclature of Construction Types, reconstructions and repair works also belong to the categories of construction. The building category also defines the institution from which the design visa is issued.


Pursuant to Ordinance No 4 of 21 May 2001 on the scope and content of investment projects, the scope of investment projects may, depending on the type, purpose, size and location of the projects and design requirements, include the following design parts:
1. Parts of architecture and structures:
a) architectural;
(b) interior and furnishings;

8. Part construction waste management plan with scope and content according to Art. 4 and 5 of the Construction Waste Management Ordinance and for the Recycling of Building Materials;
9. Other design parts for complex and complex objects:
(a) a general explanatory note;
(b) master plan;
c) Documentation;
10. Design parts for specific objects:
(a) preservation, restoration and display of immovable cultural heritage;
(b) foundation.

Co-ordination and approval of the investment project

chief architect of the region or the municipality. The co-ordination of the investment projects includes checking the correspondence with the detailed development plan, the rules and norms for construction. In cases where the contracting authority does not apply for a building permit within one year of the approval of the investment projects, the project loses its legal effect. Refusal to approve an investment project is occurs only in cases where the law has been disregarded and there has been a failute tp state the specific reasons.

Building permission

A building permit is issued by the Chief Architect of the municipality or area. It shall be issued to the contracting authority on the basis of an approved investment project. The building permit shall be issued at the same time as the investment project is approved when requested in the application. The deadline for issuance is 7 days from the receipt of the written application when there is an approved investment project. An approved investment project, when one is required, is an integral part of the building permit. The building permit can also be issued for individual stages of the works that can be executed and used on their own. For residential buildings and separate floors of the building individual stages are issued conditionally, the condition being that the architectural, spatial and facade shaping of every stage of construction is completed.


The beginning of the construction, according to the issued building permit shall take place on the date of drawing up the protocol for opening of a construction site and the designation of the building line and level Should one not be requires the date of the ordnance construction book is used as a starting point of the project.
