INTRODUCTION

The EN Eurocodes are a series of 10 European Standards, EN 1990 through EN 1999, (See Annex 1) providing a common and coherent approach to all aspects of structural design of buildings and civil engineering works, (http://eurocodes.jrc.ec.europa.eu/home.php). As standard, their application is voluntary.

The considerable interest in the adoption and implementation of the Eurocodes in Kosovo is based on the opportunity to have an advanced common standardization environment, which is adaptable to the particular requirements of the country with regard to the geographical, geological or climatic conditions which also allows selecting the level of safety. Moreover, adoption and implementation of Eurocodes will help Kosovo to gradually comply with EU acquis, which is an important factor in the accession process.

This report presents activities carried out by USAID Partnerships for Development Short-term Expert on EN Eurocodes Adoption and Implementation, as part of the overall support to the Ministry of

Environment and Spatial Planning (MESP) in the area of construction.

The specific task and activities carried out during this assignment include:

• Short description of the progress made with the adoption and implementation of the

Eurocodes in Kosovo;

• A list of potential Eurocode parts which could be transposed to Kosovo standard by using the recommended values provided by the Eurocodes;

• Sample of a National Foreword and/or National Annex templates that can be used by

Kosovo institutions for transposing EN Eurocode parts with the recommended values provided by the Eurocodes;

• Identify Nationally Determined Parameters with no recommended values by Eurocodes, and propose a roadmap for elaboration of and setting National Determined Parameters and preparing National Annexes. The roadmap, among other things, can include recommendations for cooperation with regional countries as needed to facilitate the identification of the National Determined Parameters;

• An assessment of the current environment in Kosovo for the capacities to implement

Eurocodes and based on the experiences of other similar countries (to the extent possible) propose a roadmap for facilitating the process of adoption, further implementation and promotion of the Eurocodes in Kosovo;

The performed activities within each set of specific tasks and responsibilities are elaborated briefly in the following sections.

http://eurocodes.jrc.ec.europa.eu/home.php

1. THE PROGRESS MADE WITH THE ADOPTION AND IMPLEMENTATION

OF THE EUROCODES IN KOSOVO

To better understand the progress made so far by Kosovo institutions, as a first step, all stakeholders involved in the process of adoption and implementation of the Eurocodes in Kosovo were identified, including:

• Ministry of Environmental and Spatial Planning(MESP), Ministry of Industry and Trade (MIT) and Ministry of Economic Development (MED)

• National Standardization Body – Kosovo Standardization Agency (KSA)

• Technical Committee (TC) for Eurocodes (KT 19) within KSA

• Institutions that will stream the determination of Nationally Determined Parameters (NDPs) and National Annexes (NAs) and the application and training on the Eurocodes (Universities, Research Institutions, etc.)

• Professional users of standards (Design and construction companies, National Economic

Chambers, Chambers or Associations of professionals involved in design and engineering, etc.)

In order to map the current environment in Kosovo for the capacities to adopt and implement

Eurocodes, the Project STTA conducted individual meetings with the stakeholders, as listed in the

Annex 2 of this report. Mr Arben Ajazi, as a Chairman KT19 Committee for Eurocodes and official from

Spatial Planning, Construction and Housing Department at MESP, attended all these meetings.

From the discussions with different stakeholders and research done during the assignment regarding the progress made by Kosovo institutions on the adoption and implementation of the Eurocodes, it is confirmed that:

• All 59 EN parts are received and published as Kosovo standards, among which 21 are in

English. However, neither one of the NAs is elaborated.

(http://aks.rks-gov.net/standard/index.php?national_committee_id=25&item_from=40)

• KSA has very good cooperation and bilateral agreement with the General Directorate of

Standardization (DPS) of Albania. Indeed, as a result of this bilateral cooperation, Kosovo has received and published all the 59 EN Eurocodes parts.

• Hydrometeorological Institute of Kosovo (HMIK) has limited capacity to elaborate climatic maps (snow, wind and thermal) as a part of corresponding NAs, and does not provide all necessary measurements in digital format.

• The draft seismic maps are elaborated as a result of joint efforts of the Kosovo Geological

Service (KGS) and regional experts from Institute of Geosciences, Energy, Water and

Environment of Albania. These maps are harmonized with the results obtained from NATO

SfP project BSHAP, although unfortunately Kosovo was not part of this project.

http://aks.rks-gov.net/standard/index.php?national_committee_id=25&item_from=40

• The draft seismic maps should be submitted to the KT19 Committees for Eurocodes within

KSA and their publishing as Kosovo standards shall follow standardization regulations according to the Law on standardization in Kosovo (Law No. 03/L-144).

• The representatives from academia express their willingness to participate in the process of the elaboration NDPs and NAs. They recommend broader institutional support from

Kosovo National Authorities and creation of regional platform to benefit from joint experience and efforts in this process.

• Starting from 2005, more than 90% of the design companies in Kosovo use Eurocodes for design of structures, by using the recommended values (RV), while for the NDPs without RV, previous knowledge and experience is applied, mostly former Yugoslavia regulations.

• There is a need to organize wide platform of professionals who will participate in the process of elaboration of NDPs and NAs based on their previous prioritization, as well as the need of debate among professionals concerning elaborated draft seismic hazard maps.

• The draft list of the EN Eurocodes related standards (missing in KSA Standards catalogue) which enables application of the EN Eurocodes, as well as the complete list of those standards, is delivered to the KSA.

• MESP is aware of the complexity of the whole process of adoption and implementation of the Eurocodes and its importance for Kosovo. It was emphasized that the elaboration of the construction code is one of the three essential pillars (together with elaboration of laws on construction and certification of the professionals) for successful construction reforms in

Kosovo and that MESP is and will be the driver in this process.

2. ROADMAP FOR FACILITATING THE PROCESS OF ADOPTION,

IMPLEMENTATION AND PROMOTION OF THE EUROCODES

The process of adoption, implementation and promotion of use of Eurocodes, is a complex undertaking, and as such requires very strong commitment by all parties in public and private sector, including by adequate human and financial resources. In addition, a successful implementation of the proposed

Roadmap elaborated below, depends on the following assumptions:

• Refinement of the organizational structure of KT 19, to match the CEN/TC 250 structure;

• Involvement of knowledgeable professionals in the process;

• Full membership of KSA to CEN organization, and

• Awareness of all national stakeholders of the importance of elaboration of the RV prior to the acceptance (particularly those of the partial safety factors of actions and materials). Due to the differences in the engineering and construction practice in Kosovo, compared to EU, acceptance of RV without elaboration and revision according to local conditions may have negative consequences on structural safety.

Further, a very close cooperation with all stakeholders, including external/foreign institutions, such as regional institutes, associations, and beyond, including Joint Research Centre, (JRC), is strongly recommended as such collaboration would bring additional benefits for a successful implementation of the proposed roadmap below.

Based on the Articles 8 and 11 from the Law on standardization in Kosovo (Law No. 03/L-144), the

Technical Committee for the EN Eurocodes KT 19 within KSA is responsible for all decisions regarding definition of NDPs and elaboration of NAs to SK EN Eurocode Parts. The proposed timelines for implementation of the Roadmap depend very much on the fulfillment of the above-listed assumptions, the overall construction environment in Kosovo, as well as devotion of the needed resources.

The following matrix contains the detailed proposed roadmap for elaborating NDPs and NAs, and creation of preconditions for the adoption and implementation of Eurocodes in Kosovo. Short-term, medium and long-term actions have been identified and elaborated below.

2.1 Description of the proposed actions within the roadmap

The following describes in detail all the individual proposed action/activities, as listed in the above table, separating into short-term, medium and long-term activities.

2.1.1 Short-term activities (Up to 12 months)

1. Refinement of the organizational structure of KT19 to match the CEN/TC 250 structure

Responsible: KSA, KT 19

The current Technical Committee for Eurocodes (KT 19) within KSA is established in 2016. Previously, some activities were carried out within Technical Committee for Construction (KT 1). In the current form, KT 19 consists of Chairman who is an official from MESP, Secretary (from KSA) and nine members from different relevant Kosovo institutions. The current organization structure of this

Committee should be refined so that it mirrors the organizational structure of the CEN/TC250

Committee and be able to respond to the responsibility of publishing EN Eurocodes and related EN

Eurocodes standards as Kosovo standards. This is an urgent matter and represents presumption for successful application of the proposed Roadmap.

The current CEN/TC 250 Organization Structure is given in the Fig. 1 below (See Annex3: N1250 Policy guidelines and procedures, CEN/TC 250 N 1250).

Figure 1. CEN/TC 250 Organization Structure of CEN/TC 250

Having in mind available capacities, the proposal is to refine the structure so that it consists of a

Chairman, Vice Chairman, Secretary and ten Subcommittees (SC), for each Eurocode separately (Fig. 2 below). Each SC should have Chairman and Secretary (KT 19 Secretary could act as SCs Secretary also).

The number of members in each SC may vary and depends on the number of NDPs that should be elaborated (Table 1 below). The minimum number of members in each SC could be limited to five including the Chairman of the SC. There should be no restrictions for participation of experts in more than one SC.

2. Elaboration and publishing of NAs of the SK EN parts where all NDPs have RV as

Kosovo standards

Responsible: KSA, KT 19

During this assignment, we have identified all NDPs with RV, as distributed in each of the 59 EN

Eurocode parts. Below is the list of these EN parts (Table 2) where all NDPs have recommended values, together with the number of RV for each part. As those values are recommended for use in all EU member states, and considering that the countries in the region have adopted those values for use, it is recommended that Kosovo accept the RV given in the corresponding EN Eurocode parts too.

As a part of the support to the KSA, the list of the EN Eurocodes related standards (missing in KSA Standards catalogue) which should be published as Kosovo standards, is prepared as well as generalized lists of product, test, execution and ISO standards related to EN Eurocodes (See Annex7).

4. Initiation of debate about draft seismic hazard maps as a part of the NA to SK

EN1998-1:2004/A1:2016

Responsible: KT 19, Universities, KGS, RI, experts

Kosovo is seismic prone country, so elaboration of seismic hazard maps as a country specific data is very important task. The seismic hazard maps for two different return periods (95 and 475 years), as defined in EN1998-1:2004, Clause 2.1 were drafted as a result of joint efforts of the Kosovo Geological Service

(KGS) and regional experts from Albania’s Institute of Geosciences. The official from KGS reported that draft hazard maps are harmonized with the results obtained from two NATO SfP projects

Harmonization of Seismic Hazard Maps for the Western Balkan Countries (BSHAP-1 and BSHAP-2 ) although unfortunately Kosovo was not part of it.

Acknowledging the importance of this issue and the influence of the input seismic actions to overall structural safety and resilience, it is proposed that a thorough debate with all relevant parties is organized. SC 8 leading by its Chairman should moderate the debate. In order to benefit from the EU and regional experience, the following seismic hazard maps are provided (See Annex 8):

• European Seismic Hazard Map (SHARE project, (http://www.share-eu.org/node/90)

• Probabilistic seismic hazard map for the Western Balkan Region (BSHAP-1 2011) and BSHAP-2

(2015) projects, (http://wbalkanseismicmaps.org/index.php/seismic-hazard-maps)

• RepublikaHrvatska, Karta potresnihpodrucja (http://seizkarta.gfz.hr/karta.php)

• Seismic Hazard Maps of Montenegro (un-official version), (http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2015_10_WS_Balkan)

Having in mind the importance of reliable definition of the seismic hazard maps for the overall structural safety, it is recommended that MESP asks for an opinion/revision of elaborated draft maps by relevant regional/international professional institutions.

The harmonized seismic hazard maps, as an outcome of this debate and/or proposed revision, should be submit to the KT19 and their publications as Kosovo standards shell follow standardized regulations according to the Law on standardization in Kosovo (Law No. 03/L-144).

5. Prioritizing elaboration of NDPs and NAs of the EN parts

Responsible: MESP, KT 19 and Standards users

From the exercise of mapping the current situation regarding elaboration of NDPs and NAs, it was found that Kosovo is in the very begging stage of this process. Having in mind the complexity and the amount of the work that should be done, it is recommended that Kosovo starts with the process of prioritizing the elaboration of NAs of the selected EN parts. The priority is defined in relation to:

http://www.share-eu.org/node/90 http://wbalkanseismicmaps.org/index.php/seismic-hazard-maps http://seizkarta.gfz.hr/karta.php http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2015_10_WS_Balkan

• existing links between the Eurocode (Fig. 4)

• packaging of the EN Eurocode Parts according to the Guidance Paper L (See Annex 9 and http://eurocodes.jrc.ec.europa.eu/doc/gpl.pdf)

• the result of the discussions with local stakeholders regarding existing engineering practice in

Kosovo

EN Eurocode Parts from EN 1990, 1991, 1997 and 1998 do not appear as packages, but are necessary parts of the Eurocode packages for design with particular materials. The proposed prioritization is given in the Figure 5 below. The time frame is given in the Gant chart of the proposed Roadmap (See

Annex10) and should be agreed with KT 19 who should also approve below prioritization.

6. Agreement of cooperation between National Authorities who are responsible for enforcement of standards and regulations and stakeholders in charge of elaborating the NAs

Responsible: MESP, KSA and professionals

EU member state experience shows that the process of adoption and implementation of the EN

Eurocodes was driven by several groups of national stakeholders, including:

• National authorities and policy decision makers (Ministries of Construction, Ministries of infrastructure, etc.)

• National Standardization Bodies (NSBs)

• Professional users of standards (Design and construction companies, Industry (trade) organizations, National Economic Chambers, Chambers of professionals involved in design and engineering, etc).

• Institutions that will stream the determination of NDPs and the application and training on the

Eurocodes (Universities, research institutions, Academies of Sciences, etc.)

Positive regional experiences from Croatia and Montenegro are presented below.

In Croatia, Agreement on Cooperation in the Process of Adoption of the Eurocodes as Croatian

Standards was signed on 2007 by the Ministry of Construction and Physical Planning, Croatian Chamber of Civil Engineers and Croatian Standards Institute. The firststep was preparation of the work plan for adoption of the Eurocodes as Croatian standards

(http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2013_12_WS_Balkan#Presentations).Geological, seismological, meteorological part and cartography was supported by the different state services and

Faculty of Geodesy. Financial costs for experts were covered by the Ministry and Croatian Chamber of

Engineers (http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2016_06_WS_Balkan).

Responsible institutions that participated in the process of adoption of the Eurocodes in Montenegro were the Ministry of Sustainable Development and Tourism - responsible for regulations in sectors: spatial development, construction and urban planning, Institute for Standardization of Montenegro (ISME), Institute of Hydro-meteorology and Seismology, Institute of Geology, Faculty of Civil engineering and

Chamber of Engineers, (http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2013_12_WS_Balkan#Presentations).

Following positive regional experiences, it is proposed MESP, KSA and professionals enter into a cooperation agreement to facilitate this process. The relevant Ministry could provide financial support for the experts engaged in the SC during the process of elaboration of NDPs and NAs.The model of the agreement is given in the Annex 11.

2.1.2 Medium-term activities (Up to 40 months)

1. Comparative analysis of the uploaded NDPs in the JRC Eurocode NDPs database

Responsible: KT 19, Universities, RI, experts and Standards users

Within the national framework for the implementation of Eurocodes, each country must define Nationally

Determined Parameters (NDPs) to be applied on their territory. These parameters are left open for national choice and should cover country differences in geographical, geological and climatic conditions, different design and construction practice, as well as different safety level requirements. NDPs are required for national implementation of the Eurocodes. In all 59 parts of the EN Eurocodes there are

1,506 NDPs.

In order to be able to elaborate NAs, identification of all NDPs with/without RV, as they are distributed in each EN Eurocode part, is carried out for each separate EN part, as presented in the excel table (See

Annex 12). An example of such table for EN 1998-3: Design of structures for earthquake resistance – Part

3: Assessment and retrofitting of buildings is presented in Figure 6 below. The column denoted with “Has

RV” has inserted filter which enables:

• to choose code “1” to list all NDPs with recommended values and with the description of these values, and

• to choose code “0” to list all NDPs without recommended values

Figure 6. Identification of NDPs with/without RV – example EN 1998-3

Based on this identification process, the flow chart for elaboration of each NA could be presented as below (Fig. 7). Pilot case for elaboration of NA to EN1998-3 is given in Annex 13.

2. Facilitation of regional collaboration for definition of NPDs within climatic maps and cross-border harmonization of seismic hazards and climatic maps

Responsible: MESP, KSA, KT 19, Universities, KGS, HMIK, professionals and experts

Regarding elaboration of national climatic (snow, wind and thermal) maps, during the meeting and discussion with representative from the HMIK, they pointed out that limited institutional capacity and non-availability of all necessary measurements in digital form are an obstacle for this process.

The complete tables with identified NDPs related to the snow, wind and thermal maps are delivered in the Annex 14. In the Table 3 presented below only the number of the NDPs with/without RV is given.

Table 3. Distribution of NDPs with/without RV in EN parts related to the climatic maps

EN 1991:Action on structures – Part 1-5: General actions - Thermal loads 20 6

Total 70 51

Considering complexity of the topic and limited national capacity for elaboration of climatic maps, it is recommended that Kosovo authorities make use of EU-member states experience in this filed, such as the example of Greece, Bulgaria, and Italy)

(http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2015_10_WS_Balkan).At regional level, Montenegro could serve as “know-how” model, since the Hydrometeorology Institute of Montenegro elaborated climatic maps within the frame of the twinning project MN 10 IF FI 01.

(http://www.mrt.gov.me/rubrike/eurokodovi_tvining_projekt/135788/Final-Report-Twinning-Project-MN-

10-IB-FI-01.html). It is recommended that Kosovo establishes contacts and enters into cooperation with this

Institute (http://www.meteo.co.me) who is in the possession of climatic maps.

HMIK should compile the database of all measurements they have, in order to have the necessary input data parameters for elaboration of the climatic maps.

Note: Seismic hazard maps are already discussed in the short-term action item number 4 above.

3. Elaboration of National Annex to SK EN1998-1:2004/A1: 2016 and publishing as

Kosovo standard

Responsible: KT 19, Universities, KGS, RI, experts, professionals and KSA

4. Elaboration of NAs to SK EN1991-1-3:2014; SK EN 1991-1-4:2005/AC:2016; SK EN

1991-1-5:2003/AC:2016 and publishing as SK standards

Responsible: KT 19, HMIK, Universities, RI, experts, professionals and KSA

5. Elaboration of National Annexes with priority 1,2 and 3 (See short-term action item

5)and publishing as Kosovo standards

Responsible: KT 19, Universities, RI, experts, professionals and KSA http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2015_10_WS_Balkan http://www.mrt.gov.me/rubrike/eurokodovi_tvining_projekt/135788/Final-Report-Twinning-Project-MN-10-IB-FI-01.html http://www.mrt.gov.me/rubrike/eurokodovi_tvining_projekt/135788/Final-Report-Twinning-Project-MN-10-IB-FI-01.html http://www.meteo.co.me/

The elaboration of the above listed NAs under point 3, 4 and 5 (32 in total) should follow the flow chart presented under the medium-term action item number 1 (Fig. 7), and using the template for elaboration of

NA given in the Annex 5. The institution/body responsible for their elaboration are SCs within KT 19.

After elaboration, they should be submitted to the KT19 and be published as Kosovo standards as per the requirements of the Law on standardization in Kosovo (Law No. 03/L-144).

6. Update the University curricula on Eurocodes and associated topics

Responsible: MEST, Universities, RI, experts

Currently, based on the discussion with University representatives from Faculty of Civil Engineering and

Architecture (FCEA) at the University of Pristina and UBT College, generally Eurocodes are taught and are part of the curricula in Universities for more than ten years, including some additional teaching materials. Based on the regional experience and the current circumstances, it is proposed that the current curricula is modified to include :

• Elaborated NAs

• Amendments of each EN Eurocode part, with scientific issues

• Handbooks, design aids, software, easily understandable booklets etc. to facilitate the teaching of the EN Eurocodes;

It is also proposed to introduce new subjects which would cover the new topic in EN Eurocodes, such as

Structural glass, Fiber reinforced polymers, Membrane Structures, Robustness of structures etc. to keep pace with new edition of the Eurocodes (2020). For this to happen, cooperation between teaching institutions, MESP and other relevant bodies for accreditation is necessary.

The selected teaching materials in Croatian language can be found in the following link http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2013_12_WS_Balkan#Presentations.

7. Develop a programme for seminars and training for implementation of the EN

Eurocodes in every day engineering practice

Responsible: Professionals, Universities, KT 19

It is proposed that the relevant institutions prepare a comprehensive set of materials for seminars aimed at continuous professional development and training, as well as to encourage the production of handbooks, design aids, software, etc. in Albanian language to facilitate the implementation of the EN

Eurocodes in Kosovo.

Organization of at least three two-days seminars/workshops is proposed in order to assist in training of practitioners (design engineers) to apprehend and use Eurocodes in design practice. The main topics of the events could be defined related to prioritization of elaboration of NAs (short-term activity no.5) and the actual engineering needs. The target audience could be experienced and young design engineers, master students and students at the final year of the Civil engineering faculties in Kosovo. Donor support for this proposed activity could help for an efficient implementation.

The training program is recommended to be based on the JRC Eurocode booklet B3. Level 3 of training – which comprehensively describes design examples of a number of typical structures using a particular package of Eurocodes (http://eurocodes.jrc.ec.europa.eu/showpage.php?id=33).

http://eurocodes.jrc.ec.europa.eu/showpage.php?id=33

Table 4 below presents a list of the available report – guidelines with worked examples (in English), published by EC JRC which could be used in the training program along with their links.

8. Creation of national regulatory framework for application of EN Eurocodes and

National Annexes published as Kosovo standards

Responsible: MESP, KT 19, KSA

According to the Article 7 of the Law on standardization in Kosovo (Law No. 03/L-144) implementation of Kosovo standards is voluntary. Consequentially, EN Eurocodes standards published as Kosovo standards are voluntary documents. In order to give them normative status they should be incorporate in the regulatory framework of Kosovo.

Considering general EU-MS experience regarding implementation and obligatory use of the EN

Eurocodes, (http://eurocodes.jrc.ec.europa.eu/showpublication.php?id=537), 55% of the analyzed countries (28 EU member states, plus Norway and Turkey) said that none of the EN Eurocodes Parts is obligatory, in 10% of the countries all Eurocodes Parts are obligatory, and in 35% of the countries different amount of Eurocodes Parts (varying between 6 and 46) is obligatory. However, regulatory framework enforcing the use of the Eurocodes in Public Procurement exists (or will be implemented) in

41% of the above listed countries. Croatia and Bulgaria could serve as regional examples.

In Croatia, implementation of the Eurocodes is ensured through six technical regulations (one for each type of structures: concrete, steel, composite steel and concrete, timber, masonry and aluminum) prepared by the Ministry of Construction and Physical Planning

(http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2013_12_WS_Balkan#Presentations) and

(http://narodne-novine.nn.hr/clanci/sluzbeni/2017_02_17_403.html).

The use of the Eurocodes in Croatia is not obligatory. The designer has a choice to use any other specification or scheme in order to give evidence that Basic Works Requirement (BWR) "mechanical resistance and stability" is fulfilled, but at the end of the design process, the structures must be at least as safe as those recommended by Eurocodes. Since there is no other national scheme available, the consequent result is that in practice the use of the Eurocodes is a common practice. According to the

Article 9, clause 6 of the above listed Law as published in the Official Gazette of Croatia, for structures with extremely high risk like dams, nuclear power plants, pipelines etc., except the EN Eurocodes, the special rules for design and for giving evidence that the BWRs are fulfilled, should be applied also.

General structure of the Bulgarian legislation is such that the technical requirements for construction work and products are set out in different Ordinances, Norms and Standards for: action on structures including seismic ones; design of all types of structures; foundation of all type of structures; technical systems and installation; design of all type of buildings (residential, public administrative, industrial).

(http://eurocodes.jrc.ec.europa.eu/showpage.php?id=2013_12_WS_Balkan#Presentations)

As far as the structural design concerns the citizen’s health and safety, it is obligatory to introduce the

Structural Eurocodes or Parts of them through National Ordinances. Ordinance № RD-02-20-19 of 29

December 2011 (effective as of 6 January 2012) defines the conditions and procedure for the structural design of construction works or of parts thereof by using the Eurocodes. The use of the Eurocodes for the design of new construction works for contracts awarded under the Public Procurement Act is obligatory since 2014. Also the use of the Eurocodes is obligatory for the design of new construction works of first and second category2, where for new construction works of third, fourth and fifth category, (family houses) which are not assigned under the Public Procurement Act, the design can be made with the Eurocodes or with the existing National Regulations for the design of building structures, without mixing the methods of calculation and design.

(http://eurocodes.jrc.ec.europa.eu/showpublication.php?id=537)

Having in mind that Kosovo doesn’t have existing national technical regulation for design of construction works and that the 90% of the design companies in Kosovo already use EN Eurocodes for design of structures (although not fully due to the lack of NAs), It is recommended that Kosovo regulatory framework follows Croatian example.

9. Introduction in the national legal framework compulsory seismic microzonation for

Category III constructions

Responsible: MESP, Universities, RI, experts and professionalss

According to the administrative instruction MESP No. 04/2017 on the construction categorization, category III of construction works includes all construction works of high risk and national interest.

These construction works are listed in the Annex 1 of the Law No. 04/L-110 on constructions. For definition of seismic actions on these construction works it is recommended to introduce in the Kosovo regulatory framework compulsory seismic microzonation.

10. Establish a Task Force to ensure the link between legislation on building and construction works and EN standards (particular EN Eurocodes)

2The categories are specified in Article 137 of the Spatial Development Act.

http://eurocodes.jrc.ec.europa.eu/showpublication.php?id=537

Responsible: MESP, MIT, professionals, Chamber of Commerce, University

In parallel to the SCs which should be created within KT 19, it is recommended that a Task Force3 is established, to ensure the link between legislation on building and construction works and standards and in particular EN Eurocodes and safeguarding that the Eurocodes are used in practice by the engineer as a favorable means, to prove conformity with the essential requirements in particular “mechanical strength, fire, etc”.

Experts from several ministries (MESP, MIT) shall be involved in this Task Force, but also representatives from the main stakeholders such as associations and academia. The main objectives of the Task Forces should be to:

• Ensure that the relevant building and construction works regulations provide the necessary link to the EN Eurocodes and to the related European standards (when adopted as Kosovo standards) using the legal instrument of “presumption of conformity with relevant essential requirements established in therelevant legislation”;

• Ensure that secondary legislation and specific forms to be used for tendering under the Public

Procurement Law, are in the line with the EU Directives on Public Procurement and Technical specifications, and that contract documents refer as a preferred means for design and calculations to Eurocodes and related European standards;

• Adapt relevant Curricula of technical universities to ensure that lectures on Eurocodesare provided as per the most recent developments;

• Provide proper financial resources for basic studies and background research for the elaboration/revision of National Annexes to Eurocodes whenever deemed necessary.
