2 European Technical Assessment ETA-1 6 / Page 2 of / 1 2 / Specific Part 1 Technical description of the product building units are prefabricated three-dimensional metal structures, transportable and relocatable, comprising floor, roof and walls. The units may form a building generally in conjunction with other units. The units comprise a metal frame with all the components required for structural stability. The full specification and drawings for the materials and components covered by this ETA have been examined and are retained by the CSTB. This section and the annexes give only general details of the system. The configuration of the main assembled components is shown in Annexes 1 to 3. Material and component specifications are shown in Annexes 4 to 5. The metal frame of each unit comprises two sidewall steel frameworks, each one consisting in two main beams in the short direction of the unit welded at factory site to the two columns. On each column is welded an assembly sleeve witch purpose is to be connected by means of structural rivets to the main beams of roof and floor in the long direction. The floor structure consists of floor joists riveted to the two main beams in the long direction. The roof structure consists of roof joists riveted to the two main beams in the long direction. Transportation profiles are welded to the main beams of the floor in the long direction and lifting points are welded to the columns at each corner of the units. Steel grade is mainly S350 GD for structural elements with steel protection Z275 according to EN and 618 Units properties Maximum unit length (m) 6,119 Maximum 615 unit width (m) 2,492 Maximum 618 unit width (m) 2,992 Maximum unit height (m) 2,990 Table 1 : maximum size of the units Foundations, external cladding, internal lining and floor covering are not assessed in this ETA. Windows, doors, stairs, ground floor, internal fittings, technical installations and other components which are necessary to form a complete building are not part of this ETA. The completed buildings (the works) based on the kits are not under the responsibility of ETA holder COUGNAUD CONSTRUCTION. The way in which it is ensured that the final building meets the local regulatory requirements shall be provided for on national level. The person(s) responsible for fulfilment of the essential requirements of the completed building may ask COUGNAUD CONSTRUCTION for all data and details that are necessary. 2 Specifications of the intended use The intended use of the units is the construction of temporary and definitive buildings used for example in office buildings, schools and medical buildings. The provisions made in this European Technical Assessment are based on an assumed working life of the building composed with units of 50 years for the load-bearing structure, provided that the conditions laid down in sections for the transport, storage, installation, maintenance and repair are met. The indications given on the working life cannot be interpreted as a guarantee given by the producer, but are to be regarded only as a means for choosing the right products in relation to the expected economically reasonable working life of the works.

3 European Technical Assessment ETA-1 6 / Page 3 of / 1 2 / Performance of the product 3.1 Characteristics of the product The building system was assessed only for the Basic Work Requirements (BWR) 1, 2 and 3. The results for BWR 1 are tabulated in tables 2 and Mechanical resistance and stability (BWR 1) The characteristic performance of the buildings was determined by calculation according to EN Examples of building units combination with load hypothesis are shown in Annexes 9 and 10. The structural design should confirm that, according to the structural requirements for the works, the relevant loads combination at ultimate limit state does not exceed the design loadbearing capacities given in Horizontal elements and Vertical elements of tables 2 and 3. Each line of the part Acceptable loads from above of tables 2 and 3 gives designed values element by element and for one direction of load. Seismic design shall be carried on according to EN

6 European Technical Assessment ETA-1 6 / Page 6 of / 1 2 / Safety in case of fire (BWR 2) Reaction to fire The building units are made of steel classified to have reaction to fire Class A Resistance to fire No performance determined for resistance to fire. 3.4 Hygiene, health and the environment (BWR 3) Based on the declaration of the manufacturer in accordance with Technical Report EOTA n 034, building units do not contain harmful or dangerous substances. In addition to the specific clauses relating to dangerous substances contained in this European Technical Assessment, there may be requirements applicable to the products falling within its scope (e.g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of the Construction Products Regulation, these requirements need also to be complied with, when and where they apply. 3.5 Safety in use (BWR 4) For Basic Work requirements of Safety in use, the same criteria are valid as for Basic Work Requirements of Mechanical Resistance and Stability (BWR 1). 3.6 Protection against noise (BWR 5) No performance determined for protection against noise. 3.7 Energy economy and heat retention (BWR 6) No performance determined for energy economy and heat retention. 3.8 General aspects relating to durability and fitness for use Durability Durability of the kit is acceptable in relation to the intended use and performance related to Basic Work Requirements 1, 2 and Corrosion of the metal Cold formed thin gauge members are made of steel S350 GD for structural elements, except for main beams of floor and roof in the main direction (HX 420 LAD), side purlins (S250) and transportation profile (S235). Steel protection is Z275 according to EN for all elements, except for transportation profile for witch it can be either Z275 according to EN or hot dip galvanized coatings according to EN ISO 4998 or painting according to EN ISO The estimated working life of the various parts of the kit, based on general knowledge of metal frame performance and by examining the building details which are part of the unit, related to the intended use specified in 2, is 50 years, if maintenance activities as regards in are done Serviceability Horizontal and vertical deflections are to be determined according to each building project. Values for maximal deflections at service limit state are: H/200 for horizontal deflection with H equal to the unit height; Identification L/200 for vertical deflection with L equal to the maximum floor span. The Identification parameters for materials and components of the kit are shown in Annexes 4 and 5 of European Technical Assessment. The way in which they are assembled is shown in Annexes 1 to 3. Each unit comprises an identification plate where a serial number, the date of production and the factory reference are indicated Methods of verification The assessment of fitness of the building unit for the intended use in relation to the requirements for mechanical resistance and stability and safety in use in the sense of the Basic Work Requirements 1, 2 and 3 has been made in accordance with the «Guideline for European Technical Approval of prefabricated building units».
