Technical Provisions
1. Technical description of the product
Kijk en Bouw nv produces timber frame building kits for
residential and non-residential buildings. The kid includes
external walls, internal walls, shared walls, floors and roofs.
All details of essential construction elements are given in
Annex I.
The timber frame building kits are prepared in the factory for
each individual building. Normally, the timber parts of
loadbearing constructions are prefabricated so that only
minor cutting and shaping is needed at the building site.
The mean loadbearing construction of the building is made of
a timber frame that may contain additional load-bearing
components (e.g. joists or steel girders for concentrated
loads) which, according to its structural analysis, are required
for each individual construction works.
Detailed information about the assembly of the different parts
is given in Annex II.
Material specifications are given in Annex III.
This European Technical Assessment refers to a timber frame
building kit. Complementary parts such as external claddings,
foundations, basements, metallic structural parts, surface
coverings, stairs, internal fittings, windows and doors,
technical installations of water, heating, ventilation and
electricity as well as other components necessary to form
completed works are not covered by this assessment,
although they are generally in the standard design and
delivered by Kijk en Bouw nv.
Although the external cladding is not part of the kit, it may be
delivered by Kijk en Bouw nv and it is also possible that some
types of external claddings are installed in the factory.
The kits according to this ETA may be delivered throughout
Europe. Adjustments depending on national regulations,
regulations from other authorities, special demands from
customers or specific climate conditions for the individual
building may be necessary in certain cases and are then
described in the design documentation for each individual
work.
2. Specification of the intended use(s) in
accordance with the applicable EAD (ETAG
007)
2.1 Intended use
The intended use for the building kits are residential buildings.
The building kits may also be used for non-residential
constructions as far as the required performance is met.
The intended use shall be evaluated in each individual case
depending on the climatic boundary conditions, assuming
the kit satisfies the climatic conditions for zone A, B, C and
moderate climate according to EOTA Guidance document
003 “Assessment of working life of products”
Adjustments depending on national regulations, regulations
from other authorities, special demands from customers or
specific climate conditions for the individual building may be
necessary in certain cases and are then described in the
design documentation for each individual work.
2.2 Substructure
This European Technical Assessment does not comprise the
substructure of the building
A plan drawing with the dimensions and the schematic
details of the substructure are delivered by the ETA-holder.
The substructure shall be individually designed according to
the local building regulations to correspond to the building
site.
A waterproof membrane shall be installed between the
substructure and the wood-based components according to
the construction details.
2.3 Working life and durability
The provisions made in this European Technical Assessment
are based on an assumed working life of at least 50 years3 for
the loadbearing structure and for non-accessible
components and materials and 25 years for repairable or
replaceable components and materials like claddings,
roofing materials, exterior trims and integrated components
like windows and doors, provided that the building kit is
subjected to appropriate use and maintenance.
Indications given regarding the working life cannot be
interpreted as a guarantee given by the producer or the
UBAtc, but are to be regarded only as a means for choosing
the appropriate product(s) in relation to the expected
economically reasonable working life of the construction
works.
All production of the components of the kit is performed in
dry, heated industrial halls. The materials being included in the
kits are stored indoors under favourable conditions.
The design of the timber frame building kit ensures that
deterioration of materials and components during the
assumed intended working life does not significantly affect
the performance of the kit in relation to fulfilling all the
essential requirements.
In function of the durability class of the timber components
and the intended use, the timber components can be
treated against timber-boring insects, fungus and blue stain.
The external finishes are not assessed in the framework of this
ETA. The systems shall comply with the relevant technical
specifications.
The metal fasteners and other structural connections are
either inherently corrosion resistant or are protected against
corrosion according to EN 1995-1-1/A1.
2.4 Design
The production of the components for the timber frame
building kits shall be done on the basis of a design made for
each individual delivery.
3 This means that it is expected that when the working life has
elapsed, the real working life may be, in normal use
conditions, considerably longer without major degradation
affecting the essential requirements of the works. The
indications given as to the working life of a building cannot
be interpreted as a guarantee given by the producer or the
Technical Assessment Body. They should only be regarded as
a means for the specifiers to choose the appropriate criteria
for building kits in relation to the expected, economically
reasonable working life of the works.
ETA 13/0277 - 4/38
The design process shall comply with the building regulations
applicable in the Member State in which the building is to be
erected and normally takes into account the following:
Requirements for structural design;
Fire safety requirements;
Special local requirements related to health and the
environment;
Safety in use requirements
Noise protection requirements;
Energy saving requirements.
The stiffness of the suspended floor structures is calculated
according to EN 1995-1-1/A1. The loadbearing capacities in
Annex I consider a maximal deflection of L/300 and L/500.
Suspended floors have sufficient stiffness to avoid
unacceptable vibrations from normal use.
2.5 Execution of the construction works
The manufacturer’s instructions regarding transport and
storage shall be followed.
The components and materials shall be protected against
harmful wetting during transport and storage.

to dead load or excessive bending deformation.
The components of the kit are packed to avoid damages
during the storage and transportation.
Before the installation it shall be controlled that the
components of the building kit are not damaged during
transport or storage. Damaged components and materials
shall be replaced by sound ones.
If there is a need to moodily or repair the construction this
may be done if allowed for in the installation plans. In any
case, modifications are allowed only by written consent by
the manufacturer of the kit.
The kits are erected according to the relevant description in
Annex 2. The ETA-holder provides a general manual for the
installation covering:

The height of the wall is 2600 mm. The tabulated value is a design value which is a result of a load combination. Only vertical
loads are considered in the load combination. The load combination can be computed as:
qD = 1,35 x qg,k + 1,50 x qQ,k,1 + 1,50 x ( i>1 0,i x qQ,k,I )
where qg,k is the characteristic value of the permanent load, qQ,k,i are the characteristic values of the variable loads and 0,i
the factor for combination of variable loads. The variable loads are considered to be medium term.
The design value is calculated for service class 2. Other configurations are possible and will be calculated by the
manufacturer.
Vertical design resistance for short term loading
The following table shows the vertical design resistance for the wall in combination with a short term horizontal loading. The
horizontal loading in the table is a result of a load combination. There are two possibilities:
qH = 1,5 x w (1)
qH = 1,5 x 0 x w (2)
where w is the characteristic value of the horizontal loading (for example wind). The vertical design resistance is a result of a
complementary load combination for the vertical loading :
qD = 1,35 x qg,k + 1,50 x ( i>1 0,i x qQ,k,I ) (1)
qD = 1,35 x qg,k + 1,50 x qQ,k,1 + 1,50 x ( i>1 0,i x qQ,k,I ) (2)
The result without horizontal loading is given for qH = 0 kN/m. In that case, one of the variable loads must be short term.

OSB3 – 9 mm – nails 2,4 mm x 45 mm – s = 150 mm 2,74
The racking resistance in the table is for a fully vertically anchored wall. The anchorage can be obtained by a tie down or by
dead load. When the anchorage is only partial, the racking resistance is lower. In that case, the manufacturer can give
corrected values in function of the design of the kit.
The values in the table assume structural sheeting at one side of the wall. If the structural sheeting is placed on both sides of
the wall, then:
if both materials are the same: double the values in the table above;
if plate material is different: add the values for both plate materials given in the table, but take only 75
% into account for the weakest plate material - if fasteners have similar slip moduli. In the other case,
take only 50 % of the weakest plate material.
Other configurations are possible and will be calculated by the manufacturer.
