Building permit for a prefabricated hall
Is a Building Permit Required for the Construction of a Hall?
For the construction of a prefabricated hall whose structure consists of solid-web or truss beams or a reinforced concrete structure anchored to foundation pads, strips, or piles, and is clad with sandwich panels or trapezoidal sheets, a building permit is always required by law. There is also a variant of the hall where (textile) PVC cladding is used without the need for complex foundation structures. In this case, only a notification is required, provided the hall is “...up to 1,000 m2 of built-up area and up to 15 meters in height, with at most one above-ground floor, not basemented, and the period of use does not exceed three years.”
Unfortunately, the time limit for the use of the hall in this case is highly unprofitable for most investors, which is why they choose to obtain a classic building permit for a hall with a longer lifespan and broader usage possibilities.
The content and requirements of the project documentation for a building permit are governed by Building Act No. 183/2006 Coll.
Stages of Project Documentation
Architectural Study
The simplest form of project documentation is the architectural study, which is prepared to present the concept of the building to the client. It is based on their requirements and its aim is to offer the optimal solution. The study addresses the investor’s requirements regarding layout, materials, and aesthetics, as well as integration into the surrounding landscape and terrain, including utility connections. It is prepared in the form of simple drawings, and usually several variants are created. The architectural study may also include a visualization for better imagination. It is not submitted to authorities, so its content is not precisely defined by regulation.
Documentation for Zoning Procedure (DÚŘ)
The next stage is documentation for zoning procedure (DÚŘ), which is prepared in cases where the land intended for construction is not approved for building purposes by the zoning plan. This stage of project documentation precedes the building permit and in some cases, it is possible to combine both procedures. The documentation most often addresses the impact on the environment or agricultural land fund and serves as a basis for the decision of the building authority regarding the development of the selected area and the issuance of a zoning decision.
Project Documentation for Building Permit (DSP)
The project documentation for building permit (DSP) usually follows the Zoning and Planning Decision (DÚR). It contains the actual structural, spatial, and material design of the building according to the client's requirements, so that it complies with public interest requirements (e.g., transport, energy, or hygiene).
It includes:
- technical and accompanying report,
- construction and site drawings,
- structural design solutions,
- fire safety (PBŘ),
- utility connections,
- building technical systems (water supply, sewage, heating, electrical installation, gas distribution, lightning protection),
- Energy Performance Certificate (PENB)
Based on this project documentation, it is possible to obtain statements from all participants in the building procedure, which are primarily the owners of neighboring plots and the administrators of the affected networks. Based on this documentation, all statements, and positive opinions, the actual building procedure can be initiated.
Documentation for Construction Execution (DPS)
Subsequently, the documentation for construction execution (DPS) is prepared. This is a thoroughly developed documentation with specific technical solutions used to create a bill of quantities for the construction and for its actual execution. It also serves as a basis for construction supervision, which uses it to check the correctness of the work being carried out, and it is also used as a basis for selecting the construction contractor.
As-Built Documentation (DSPS)
In the event that there are major changes compared to the documentation for the building permit during construction, after the completion of the building as-built documentation (DSPS) is prepared, which is submitted for the final inspection (occupancy approval) of the hall. According to current legislation, every property owner is required to have it available, and it is often prepared during the reconstruction of existing buildings.
The individual stages of documentation are briefly described above. You can find the complete points and contents in the Building Act No. 183/2006 Coll. Building Act.
The building procedure ends with the decision of the building authority. If the application is approved, a building permit is issued. This contains the conditions under which the construction is to be carried out and, if applicable, used. You can appeal the decision of the building authority within 15 days of delivery.
The validity of the building permit is time-limited. Construction must begin within two years from the date the building permit becomes legally effective. Otherwise, the building permit loses its validity.
An expired building permit means that a new building procedure must be initiated.
The two-year period of validity of the building permit can be extended if the builder submits a justified request for extension before it expires.
For the building permit documentation, let us now focus on the fire safety solution of the hall. This fundamentally affects other parts of the documentation.
The content and scope of the fire safety solution is determined by the decree on fire prevention, specifically provision § 41 paragraph 2 of Decree No. 246/2001 Coll., on fire prevention as amended.
The fire safety solution for the building permit or for a change in the use of the building is prepared based on the submitted construction drawings and building description by an authorized person, and the Fire Rescue Service issues, based on a written request, its binding opinion within 30 days.
Based on the requirements arising from the fire safety report, the supplier of the prefabricated hall must propose the correct structural solution for the hall and use materials, especially the type of roof and wall cladding, that correspond to the declared requirements of the report. Without meeting the requirements of the fire safety report, it would not be possible to successfully obtain occupancy approval for the hall. The type of materials used is linked to another point of the project documentation, the Energy Performance Certificate (PENB).
PENB, or the Energy Performance Certificate of the building, is used to assess the energy performance of the building – it quantifies all the energy consumed during the standardized operation of the assessed building and classifies the building into the appropriate class in the range A-G. The certificate evaluates all energy needed for the operation of the building, i.e., energy for heating, hot water preparation, cooling, air treatment by ventilation and air conditioning, and energy for lighting. The certificate can be prepared for any building or its complete part. The certificate is valid for 10 years from the date of issue or until a major change is made to the completed building for which it was prepared. The certificate can only be prepared by an energy specialist authorized to do so.
You can find more information in Act No. 406/2000 Coll., on energy management, and in Decree No. 78/2013 on the energy performance of buildings.
For these reasons, it is advisable, right from the very initial intention to build a hall, to determine the exact purpose the hall will serve and to coordinate the design work together with the structural solution of the hall. Therefore, contact us and we will help you find an effective and economical solution for your hall without unnecessary delays and compromises. The simple rule applies that quick acquisition of a building permit relies on well-prepared project documentation.
