0.1MEANING AND SCOPE OF THE TECHNICAL GUIDELINE ON PROTECTION AGAINST NOISE IN BUILDINGS
0.1.1 Legal basis for the issuance of the Technical Guideline
This Technical Guideline was issued by the Minister of the Environment and Spatial Planning in agreement with the Ministry of the Economy on the basis of Article 11(1) of the Construction Act (Official Gazette of RS, nos. 102/04 – official consolidated text, 14/05 – corrigendum, 92/05 – Public Roads Act (ZJC)-B, 93/05 – Veterinary Compliance Criteria Act (ZVMS), 111/05 – Constitutional Court Decision, 126/07, 108/09, 61/10 – Mining Act (ZRud)-1, 67/10 – ZRud-1A and 20/11 – Constitutional Court Decision).
The Construction Act defines a technical guideline (Article 2(1) point 3.2) as "a document laying down, for specific types of buildings, a detailed definition of the essential requirements, design requirements, selected levels or classes of construction products and materials allowed to be installed and the methods for installing them, and construction methods, for the purpose of ensuring building reliability throughout the life cycle where applicable, as well as procedures for determining the fulfilment of such requirements".
The legal nature and application of technical guidelines are specified in detail in Article 9 of the Act, which stipulates that building regulations (a type of implementing regulations issued on the basis of the Act) must define technical characteristics of specific types of buildings in such a manner as to have those buildings fulfil, in line with their intended use, one, several or all of the essential requirements listed below:
- Mechanical resistance and stability,
- Fire safety,
- Sanitary, health and environmental protection,
- Safety in use,
- Protection against noise, and
- Energy saving and heat retention.
The foregoing provision further stipulates that building regulations may rely on standards or technical guidelines concerning specific types of buildings to lay down their mandatory use and stipulate that the presumption of compliance with the building regulation requirements will exist where an element is compliant with the requirements of those standards and technical guidelines. Where building regulations stipulate a presumption of compliance, they must also define the competent decision-making authorities and the procedure to be applied in proving that a building not compliant with the standards and technical guidelines, in which the architect applied state-of-the-art building technique solutions, will ensure at least the level of safety provided by a design drawn in compliance with the standards and technical guidelines.
State of the art building technique (Article 2(1) point 3.1 of the Act) is defined as a state which constitutes, at the time of drawing up design documentation or at the time of construction, the latest level achieved with regard to technical capacity of building products, processes and services, based on recognised results of scientific and technical research and experiences in the field of building construction, at reasonable expense.
0.1.2 Rules on protection against noise in buildings – legal framework for the application of the Technical Guideline
The Rules on protection against noise in buildings are provided by the building regulation defining in detail the essential "protection against noise" requirement. The Rules lay down the requirements for the protection of buildings and units and parts thereof against:
-Outdoor noise (such as traffic noise, industrial noise),
-Airborne noise transmitted from other units,
-Impact noise, structure-borne noise from other units,
-Service equipment noise and
-Reverberation.
The part of the Rules setting out the manner for fulfilling the statutory requirements contains the following provisions essential for the application of this Technical Guideline:
Article 7
(Technical Guideline application)
(1) The Minister in charge of construction shall issue the construction technical guideline TSG-1-005Protection against noise in buildings, laying down recommendations for construction measures and solutions necessary to satisfy the requirements of these Rules.
(2) Where the measures specified in the Technical Guideline or in documents to which it refers have been fully applied in the design and implementation of protection against noise, these Rules will be deemed to have been complied with.
Article 8
(Application of other measures)
(1) When designing and implementing protection against noise, state-of-the-art building technique solutions ensuring at least an equal level of protection to the design drawn in compliance with the Technical Guideline may be applied instead of the measures specified in the Technical Guideline.
(2) The measures referred to in the preceding paragraph shall mean the application of state-of-the-art building technique solutions in accordance with the CA-1. In such a case, compliance with the requirements set out in these Rules shall be checked in accordance with Article 11 of these Rules.
(3) Notwithstanding the first paragraph of this Article, the actions specified in Articles 9 and 12 of these Rules shall in any event be undertaken strictly in the manner specified in the Technical Guideline.
The following provisions are essential for the section of the Rules laying down the contents of design documentation:
Article 9
(Indication of design basis and mandatory parts of the project)
(1) The project manager in charge shall indicate in the General building information section of the main file (form 0.4, point "Other classifications") whether the building permit design was drawn on the basis of the Technical Guideline or of Article 8 of these Rules.
(2) The protection against noise in buildings study shall form an integral part of the building permit design and shall contain all the data and calculations specified in Article 10 of these Rules.
(3) The Protection against noise in buildings statement referred to in the Technical Guideline shall also form an integral part of the building permit design. It shall be completed in the manner specified in Article 10(4) of these Rules, with the "Design values and planned measures (calculated values)" section completed.
Article 11
(Revision obligation)
(1) In addition to the cases specified in the CA-1, the revision of the building permit design shall also be mandatory where an engineer designs a non-complex building in accordance with Article 8 of these Rules; in such a case, the revision shall be carried out following the procedure and with the participation of the persons laid down in the CA-1.
(2) The object of the non-complex building revision referred to in the preceding paragraph shall be a review of the Protection against noise in buildings study and technical control of those architectural plan and mechanical installation elements of the building permit design which provide evidence that the submitted design fulfils the requirements of these Rules at least to the extent it would were the Technical Guideline and documents listed therein applied.
(3) The reviser in charge shall enter into the revision report summary all the data of importance for the scope of the revision referred to in the preceding paragraph in accordance with the regulation governing design documentation. By signing the revision report, the reviser shall only confirm that the design satisfies the requirements of these Rules.
The Rules on design documentation (Official Gazette of RS, no. 55/08) must also be taken into account with regard to the mandatory elements of the Building physics study for the field of protection against noise.
0.1.3Legal consequences of (non)compliance with the Technical Guideline
a) Technical Guideline application – presumption of compliance
As indicated in the preceding points of this Introduction, the construction measures and solutions laid down in this Technical Guideline are only recommendations for the fulfilment of requirements for protection of buildings against noise set out in the Rules. Observance of the recommended construction measures serves as a basis for the presumption of satisfaction of the requirements outlined in the rules.
In the event of application of this Technical Guideline, the burden of proof of non-compliance with the requirements of the Rules lies with the competent authorities or statutory construction participants, whose role is to supervise design compliance. Where the design process was in compliance with the construction measures laid down in this Technical Guideline during construction and the obtaining of the necessary administrative decisions, compliance with the relevant regulations need not be proven, as it is presumed under the Rules.
b) Design applying state-of-the-art building techniques
Where the architect in charge decides, in accordance with the Rules, to apply (in part or in full) state-of-the-art building technique measures as defined in Article 8 of the Rules, a mandatory revision of design documentation, which constitutes the statutory method for proving compliance by the architect in charge, serves to prove that at least an equal level of protection against noise has been ensured; this applies to non-complex buildings as well.
c) Reconstruction and maintenance of existing buildings
With regard to building reconstruction, Article 1(2) of the Rules on protection against noise in buildings lays down a general restriction on the application of the Rules by stipulating that the Rules shall apply to reconstruction where technically possible and not contrary to heritage protection conditions. In addition, Article 9(5) of the Construction Act lays down a general restriction on the application of the Rules on protection against noise in buildings in the case of building reconstruction, stipulating that designed or built solutions may deviate from the statutory requirements. This means that, in building reconstruction or construction having a direct impact on protected heritage, the measures proposed in this Technical Guideline should be replaced by an alternative combination of building and technical measures taking into account the established limitations and conditions, which best contributes to the fulfilment of the statutory requirements in the area of protection against noise. Alternative solutions should be sought either for the entire building or for parts thereof.
The Rules apply to reconstruction and maintenance of existing buildings where the sound insulation of external separation elements must be improved due to increased outdoor noise levels.
d) Relation to the requirements of regulations governing protection against noise in buildings
The content of this Technical Guideline recommends construction measures which may exceptionally be subject to specific legal regulations. In relation to the regulations in force, the Technical Guideline was drafted so as not to put the proposed construction measures in conflict with the requirements of those regulations. If, during its application, it is nonetheless found that the implementation of a specific proposed measure would constitute a violation of the regulation in force, the statutory requirements must be fully complied with.
Point 0.2.1 takes into account the regulations in force on the date of issuance of this Technical Guideline. Users must follow the Official Gazette of the Republic of Slovenia, or, in case of decisions and ordinances of the European Council, the Official Journal of the European Communities, for any amendments associated with the issuance of new regulations and abrogations connected therewith.
