ADVANTAGES
Individual scope for architectural design
M1 BSP crossplan provides architects and planners with new
design freedom as there is no need to adhere to any particular
pattern. This high degree of fl exibility in planning allows
for customised solutions to a variety of building tasks.
The use of cross-laminated timber panels creates new attractive
possibilities and forms of expression in the architecture
of modern timber constructions.
High degree of prefabrication
M1 BSP crossplan is cut to size at the factory by our computer-controlled
CNC machining systems on request.
The extremely high degree of prefabrication results in short
assembly times and, hence, to lower building costs.
The ready-to-assemble elements are of a consistently high
product quality and minimise the risk of assembly errors due
to accurately fi tting components.
Solid construction
Solid construction using M1 BSP crossplan not only fulfi ls the
traditional advantages of solid building structures but optimises
them with lower component thicknesses, lower transport
weight, shorter building times and outstanding structural
properties.
The solid, cross-wise layered construction and the innovative
production process are the reason why M1 BSP crossplan
keeps its excellent shape and dimensional stability.
This signifi cantly simplifi es design and building with M1 BSP
crossplan as there is no need to allow for tolerances and
changes in shape.
Version 1 / 2011

ADVANTAGES
Excellent structural properties
Thanks to its outstanding structural properties M1 BSP crossplan
opens up new opportunities in modern timber construction.
The high load-bearing capacity with lower dead weight
allows tight dimensioning of the components even in large
span applications. This results in wall cross-sections well below
any other building materials. Consequently creating more
living space with the same outer dimensions.
The special cross-wise layered construction of M1 BSP crossplan
results in all-round load transfer that makes it ideal for
use as a panel or diaphragm. Point-supported structures or
projections across corners are unproblematic.
What’s more M1 BSP crossplan enables earthquake-proof
construction.
Outstanding environmental life cycle assessment
The raw material for the manufacture of M1 BSP crossplan
mainly originates from domestic forests. For generations,
these forests have been managed and tended according to
the principle of sustainability which means, therefore, our
raw material is not only always available but is also replanted
on a sustainable basis. This is also confi rmed by our 100 %
PEFC certifi cation.
In addition, timber is the only building material that is distinguished
by its positive contribution to the carbon footprint.
For this reason, building with timber constitutes an active
contribution to climate protection.
Recommended for environmentally compatible
architecture
Timber lends a pleasant ambience to rooms and is distinguished
by its visual appeal. It also conveys a sense of cosy
familiarity and warmth.
The perceived surface temperature of M1 BSP crossplan lies
signifi cantly above any other type of building material. Even
at lower room temperatures this leads to a pleasant perception
of temperature.

TECHNICAL DATA
M1 BSP crossplan is a large-format, solid timber panel (cross-laminated timber panel) with
multi-layered, crosswise laminated lay-up.
Finger-jointed and planed lamellas are loosely laid next to each other and the fl at surfaces of
the layers glued at right angles to one another.
To avoid uncontrolled stress cracks, the narrow sides are not edge-glued.
The layers are pushed laterally to dimension before applying the pressure (1,2 N/mm 2 ) in
order to obtain a gap-free surface.

M1 BSP crossplan is supplied in two surface qualities.
SURFACE QUALITIES
For non-visual applications in compliance with all structural requirements, for subsequent
installation (e.g. plasterboard).
• The top lamellas are exclusively sorted according to the sorting criteria of the loadbearing
strength C24 in line with EN 338. A proportion of max. 10 % C 16 is permissible
(ETA-09 / 0036).
• Colour variations of individual lamella (e.g. blue stain) as well as loose knots, bark
ingrowths and resin pockets are permitted.
• Isolated gaps in the outer layers, glue stains as well as isolated pressure points and
markings can appear
• Planed surface only
With additional requirements for a visual application.
• Stringent visual criteria for outer layers are applied in addition to the sorting criteria for
load-bearing strength.
• Selected outer lamellas with healthy intergrown knots. A few isolated loose knots are possible,
defects and small resin pockets are permissible.
• Planed and sanded surface.
Timber is a natural product. Variations in the surface quality can occur with even the most
careful selection of the raw material.
The appearance of the M1 BSP crossplan surface is determined by the board structure of
the top layer. Gaps may occur between the individual boards over time due to shrinkage, etc.
Drying checks are also possible.

Version 1 / 2011
M1 BSP crossplan
Components made of M1 BSP crossplan are designed and executed according to the following
standards:
• Design according to DIN 1052:2008 allowing for German technical approval
(Z-9.1-638)
or
• Design according to EN 1995 (Eurocode 5) allowing for Appendices 2 to 4 of European
technical approval ETA-09 / 0036
The structural analysis for M1 BSP crossplan must be conducted in each individual case and
the standards and regulations applicable at the site of use must be complied with.
Analysis of the stress distribution and internal forces and moments must be conducted according
to the composite theory allowing for shear deformations.
An approximation method is required in practical use. Here, the calculation is carried out as
for a beam under bending moment with fl exible joining means (Austrian standard B 4100 / 2;
DIN 1052; EN 1995-1-1, Appendix B), but the shear deformation of the transverse layers is
taken into consideration instead of the fl exibility of the joining means.
Using this approach, it is possible to achieve a good approximation for the stress and deformation
calculations.
At the same time, for the actual design the moments of inertia are multiplied by a reduction
factor - which takes into account the net moments of inertia and the rolling shear deformation
of the transverse layers.
Using the eff ective moments of inertia (Ieff ) obtained as a result, it is possible to calculate
the cutting forces and deformations as for beams under bending moment with a rigid bond.

Note:
The solution only applies exactly for single span beams with sinusoidal uniform load. It should
also be noted that the eff ective moments of inertia Ieff depend on the width between supports
of the panels. The shorter the width between supports, the greater the proportion of
shear deformation and thus also the percentage reduction of the moments of inertia (compare
table of cross-sectional values). Beyond this, a more accurate calculation method is
necessary particularly in the case of point loads and very short beam lengths.
In the case of continuous beams, the width between supports of the fi eld concerned should
be used for the width between supports for selection of the eff ective moment of inertia 4 / 5
Ieff , in the case of cantilever beams double the protruding length should be used (cf. EN
1995-1-1, Appendix B). However, calculation of the cutting force and deformation must be
performed using the actual widths between supports or protruding lengths.
This approximation method is also the basis of the design charts.

STRUCTURAL DESIGN
The stress perpendicular to the panel plane is applicable for the design. Analysis of the stress
distribution and internal forces and moments must be conducted according to the German
technical approval (Z-9.1-638) in line with the composite theory referred to above allowing
for shear deformations (DIN 1052:2008, Appendix D).
The various bending stiff nesses of the relevant clamping directions must be allowed for in the
panel stress. That is to say, that in the longitudinal direction of the panel (main load-bearing
direction) the lamella layers may be taken into consideration in the panel’s longitudinal direction
and in the transverse direction of the panel the lamella layers may be taken into consideration
in the panel’s transverse direction.
If the panel lay-up transverse to the direction of span corresponds to the lay-up of a 3-layer
panel, then the cross-sectional values must thus be taken from the table (page 11).
Note:
In the case of 3-layer panels, when designing transverse to the main load-bearing direction,
the middle layer must be calculated as a solid timber cross-section.
In the case of stress in the panel plane, only those layers where the fi bre direction runs
parallel to the force components considered may be taken into account (German technical
approval Z-9.1-638).
The following models must be diff erentiated when designing in the panel plane.
In the case of stress as a wall slab (bracing ceilings and walls), it is necessary to conduct
the corresponding shear stress analyses in accordance with the German technical approval.
Only the lamella layers running parallel to the direction of force or direction of internal forces
and moments are taken into account for the design. The height of the individual beam crosssections
must be specifi ed in a particular case. Thus wall slabs may also be calculated allowing
for door and window openings.
Only the lamella layers running parallel to the direction of force are taken into account for
the design of the load carrying capacity in the panel plane. The buckling analysis required
for this must be conducted according to the equivalent member method in accordance with
DIN 1052 or EN 1995. The corresponding slendernesses (λ) and the associated reduction
factors (κ) must be determined in the process.
It must be ensured that impacts on components or supporting structures that are to be
anticipated frequently do not give rise to any vibrations which could impair the structure’s
function or lead to unease. The required analysis must be conducted in accordance with
EN 1995-1-1 whereby a special investigation must be carried out for apartment ceilings with
a resonant frequency not exceeding 8 Hz.
Note:
When conducting an analysis in accordance with DIN 1052, the defl ection on the ideal single
span beam must be determined from the continuous and quasi-continuous load. With a
defl ection of more than 6 mm, a separate analysis must also be performed.
The fi re resistant design of M1 BSP crossplan is carried out in accordance with EN 1995 or
DIN 1052 / 4102 (referred to as thermal design with inclusion of the residual load-bearing
capacity). Charring rate: See technical data on page 6

STRUCTURAL DESIGN
Design of the cross-laminated timber may be carried out according to EN 1995-1-1 and EN
1995-1-2 allowing for Appendices 2 to 4 of the European technical approval. Only lamellas
which are arranged in the direction of the mechanical stress may be taken into consideration
for calculation of the characteristic cross-sectional values. Reference must be made to the
characteristic strength and stiff ness of the solid timber according to to Appendix 3 (of European
Technical Approval 09-0036) for designing the components made of cross-laminated timber
in accordance with E 1995-1-1. Diff erent stiff nesses must be taken into consideration in both
main directions for cross-laminated timber with multi-axial spaning in both main directions.
Panel stress of the cross-laminated timber
The eff ective bending stiff ness depends on the eff ective moment of inertia Ieff . Calculation of
the eff ective moment of inertia and therefore of the eff ective bending stiff ness time is carried
out acc. to E 1995-1-1 (Section 9.1.3 and Appendix B):

The following equations may be used for stress in the panel plane (slab stress) under the
requirements of the technical column theory:
Thickness of the lamella layers in the direction of stress
Thickness of the lamella layers normal to the direction of stress
� Distances between centres of gravity:
Maximum
where
Design value of the shear force
Calculation of the bending stresses and bending stiff ness may be carried out using the full
section of the lamella layers in the direction of stress. When calculating the shear stresses,
the net area with the smaller cross-section of the two stress directions is decisive.

The load-carrying connection of M1BSP crossplan elements must be carried out separately
and using suitable joining means for each building task. The design of the connecting means
(diameter, number und distances) should be within the responsibility of a specialist familiar
with cross-laminated timber.
As a recommendation for determining the design values, reference is made to «Bemessungsvorschläge
für Verbindungsmittel in Brettsperrholz» [Design Suggestions for Joining Means
in Cross-laminated Timber] [from Bauen mit Holz [Building with Timber] 111 (2009), BLASS
Hans Joachim, UIBEL Thomas] and to Expert Opinion no. GU07-4-2-1-01 and GU11-402-1 of
the Technical University of Graz. Specifi ed here are the embedment strengths for screwed
and nailed joints, dowel pins, fi t bolts and bolts, in addition to a design suggestion for axial
stress (tension).
A distinction should be made between joints in the narrow surfaces and those in the lateral
surface when referring to joints. The static analyses of the joints must be conducted in
accordance with EN 13501 -1-1.

ORDER PROCESSING
We off er our partners quality, reliability and an innovative range of high-quality products. Our
aim, therefore, is to make the processing of enquiries and orders as clear and effi cient as
possible.
The quality and level of detail in our quotes depend on the details in the enquiry and the
validity of the tender texts (e.g. measurement details, span widths, load systems, snow loads,
dimensioning, etc.).
a) Basic tender text
Quotes based on enquiries specifying only overall square metres and without detailed
plans involve inaccuracy of up to 10% (cost estimates). The dimensioning of the panels is
only possible with appropriate detailed information (loads and span widths).
b) Building permission plan
A building permission drawing has a higher validity than the basic tender text. It is possible
to produce an accurate quote at short notice if appropriate measurements, construction
details and regional information for assumption of the snow loads are provided.
c) CAD drawings
On the basis of clearly defi ned dimensions of the panels we are able to prepare a binding
quote immediately.
The exact delivery location and maximum panel sizes are decisive for calculating the freight
costs.
Our order confi rmation is issued once the customer has placed the order. This confi rmation
contains the fi nished project design including element usage and exact representation of
the elements in the form of planning documents. All measurements, surface conditions and
machining measures are thus clearly defi ned.
This data is given to the customer with a request for counter-signature. The counter-signature
is valid as the customer’s approval for planning and production and as the start of the delivery
period specifi ed.

Version 1 / 2011
M1 BSP crossplan
At the same time as approval is given for production, detailed loading plans are drawn up in
consultation with the customer. Agreement must be reached here between the customer’s
wishes and the practical possibilities of unloading.
The legal regulations regarding securing of the cargo have been tightened up considerably
recently and compliance with them is inspected very carefully, the result being that unfortunately
it is often necessary to deviate from the best loading sequences.

24 Mayr-Melnhof Kaufmann
TRANSPORT
The transport will be scheduled once the loading plans and delivery dates have been defi ned.
Special transports are almost always necessary because most of the loads contain components
with lengths exceeding 13,60 m and / or widths or heights exceeding 2,50 m.
These special tranports require national and international road use permits and should,
therefore, only be carried out by carriers familiar with them and equipped for the task.
The transport costs referred to include 2,5 hours for unloading of the lorry at the building site.
Each additional hour of the lorry’s waiting time will be invoiced additionally if delays occur
during unloading.
The elements may be transported either upright or fl at.
Component deliveries lying fl at are particularly appropriate for panels with less machining
(e.g. ceiling elements) or raw panels. This is also the more cost-eff ective variation for widths
up to 3,00 m as platform semi-trailers may be used without additional structures. Appropriate
ex works protection against dirt is guaranteed by packaging in plastic foil.
Upright element transport is used primarily for material with a high level of machining such
as walls with window and door cut-outs, visible components, and similar. The use of fl atbed
semi-trailers with appropriate loading area structures is, however, more expensive than transport
elements lying fl at using platform semi-trailers.
The basic principles of timber storage must be observed where it is necessary to store
M1 BSP crossplan.
M1 BSP crossplan elements may be provided with assembly aids. These are used to manipulate
the elements at the plant and on the building site. Loops or special screw systems will be
used depending on the type of component and size. The number of assembly aids attached
depends on the safety requirements and the measurements of the relevant components.

The basis of every M1 BSP crossplan invoice is the unit m 2 and the surface condition in industrial
quality.
The smallest circumscribed rectangle based on the fi nished dimension of the nearest grid
width is always applicable as the invoicing area. This gross measuring system also includes
recalculation of all openings typical of residential buildings. Generally speaking, the basic
calculation includes free, right-angled cutting to format of each element.
All additional services are presented in a transparent surcharge system to make the pricing
policy easy and clear for the customer.

TENDER TEXT
The following tender text refers to a shell construction made from cross-laminated timber
panels and is intended to be used as a guideline which may be adapted to the relevant building
project and the specifi c circumstances. Custom joinery works and component joints
must be defi ned as accurately as possible with sketches and drawings as necessary.
We will be grateful to supply the sample text in MS Word format on request.
Multi-layered glued, large-formatted panel elements, minimum width 2.40 m, made of spruce
for structural use as wall, ceiling or roof elements. The planed lamella layers are each arranged
off set at 90° to each other and glued together under high pressure (at least 1,2 N/mm 2 ) over
the entire surface.
The dimensionally stable elements are layed-up symmetrically to the central plane in crosssection.
Only Melamine-adhesives approved for load-bearing timber components in interior and exterior
use (class of use 1 and 2 according to ÖNORM EN 1995-1-1) are permitted. The moisture
content of the lamellas used is 12 % (+/- 2 %). Surface quality – unless noted otherwise in the
position – is industrial quality. The M1 BSP crossplan panels may not be fi ngerjointed (panel
to panel connection).
In order to prevent uncontrolled stress cracks, the individual lamellas may not be edge-glued
together on the narrow side.
The airtightness of the 3-, 5- or 7-layered M1 BSP crossplan element is a basic requirement.

Industrial quality: Industrial quality is intended for construction applications, for subsequent
installations by the customer (e.g. plasterboard). The top lamellas are exclusively sorted
according to the sorting criteria of the load-bearing strength C24 according to EN 338.
A proportion of max. 10 % C16 is permissible (ETA-09 / 0036) Color variations of individual
lamellas (e.g. blue stain), as well as loose knots, ingrown bark and resin pockets are permitted.
Isolated gaps in the outer layers, glue stains as well as isolated pressure points and
markings may appear.
Standard quality: With additional requirements for a visual application. Stringent visual criteria
for outer layers are applied in addition to the sorting criteria for load-bearing strength.
Selected raw material with healthy, intergrown knots. A few isolated defects such as loose
knots and small resin pockets are permissible. The surface is planed and sanded.
Cross-laminated timber requires a certifi cate of usability by means of European technical
approvals (cross-laminated timber – solid panel-shaped timber construction elements for
load-bearing components in structures, e.g. ETA-09/0036) or German technical approval
(e.g. Z-9.1-638 for M1 BSP crossplan), in which the panel construction and layer thickness
as well as strength and stiff ness characteristics are specifi ed.

Our factory at Gaishorn
INNOVATIVE SOLUTIONS
FOR DEMANDING CUSTOMERS
It was in the Styrian municipality of Gaishorn am See in
Austria that the most important production site for laminated
timber was fi rst set up in 1991. Known by the name of «Systemholz»,
these standardised laminated timber beams met
with a brisk demand in the markets of Italy, Germany and
Austria.
After gradually expanding the factory‘s production capacity
and investing in a new manufacturing facility for its innovative
cross-laminated timber panels, the Gaishorn site now houses
three plants for laminated and one for cross-laminated timber,
plus a sorting plant and nineteen drying kilns.
Since 2009, the plants have been operating under the name
of Mayr-Melnhof Kaufmann Gaishorn. With a capacity of approx.
200.000 m 3 for laminated timber and 60.000 m 3 for
cross-laminated timber, plus a CNC centre for cross-laminated
panels, the site is one of the leading and most modern
production facilities for wood engineering materials in
Europe.
Your distributor:
The basic raw material used in laminated timber and
M1 BSP crossplan is locally grown wood from sustainably
managed forests. State-of-the-art electronic sorting and testing
machines guarantee the highest quality.
Effi cient high-frequency press technology is available for fulfi
lling unusual customer wishes in a short space of time. Internal
and external inspections are conducted by independent
testing institutes on a regular basis to ensure the highest
possible product quality and safety.
