The Structure and Conceptual Model project
• The Swedish Transport Administration (Trafikverket) is the Government agency
responsible for the long-term planning of the transport system. Trafikverket is
also in charge of the state road network and national railway network.
• Trafikverket shall implement a common co-ordinated information systematic
• The systematic shall be used
– For describing resources, processes, results and properties of interest
– Throughout the whole chain of planning, design, production and asset
management of Trafikverket’s road and railway network
– Both for BIM and for established applications in the processes
• The work includes classification of every object of interest for defining
requirements, in planning, design, production, and asset management
• The work will be carried out in sector wide cooperation with leading
companies.
• The new systematics will replace the current BSAB 96

ISO/FDIS 12006-2:2013
• The standard for building
classification ISO 12006-2 has
been revised to support e.g. BIM
and new metods of construction
procurement
• New status: ISO/FDIS 120062:2013
• Every part of a construction entity
shall be classified according to the
same principles of subdivision, i.e.
function, form and/or position
• Enables mapping between
national tables

The new definition of Construction elements
supports existing classifications as well as
applications within BIM.
Before: ”construction entity part which, in itself or in
combination with other such parts, fulfils a
predominating function of the construction entity”.
This definition only mentions function as subdividing
property
Now: ”constituent of a construction entity with a
characteristic technical function, form or position”.

Use function and general
technical solution
• Use, including production, operation and maintenance, places
demands on use functions of various types (load carrying capacity,
privacy, climate, media, maintenance intervals, etc.).
• In the design of construction entities an assumption of a general
technical solution that can satisfy use functions is made, e.g. a
house, road or bridge, where construction elements with the
intended function and shape has been determined.
• Examples include roofs, walls, floors and foundations for houses,
roadway, hard shoulder and embankment for roads, and bridgeway
and bridge structure for bridges, each with their use functions,
shape, and position.
7
Constructive function and
detailed technical solution
• The detailed design is made as technical solutions for each of the
construction elements
• These technical solutions are in turn composed of building
elements, eg, trussed rafter, stud frame, precast concrete slab,
bitumen bound surface course, in situ concrete bridge way
construction
• Construction elements in detailed technical solutions have different
constructive functions.

Construction elements in different levels
support design
Construction elements: parts of construction
entities with function, form and/or position
Function: bonding relation between things.
Function can be in relation to user activity and
environment (use function) and to other
construction elements (constructive function)
Technical system: system of construction elements
in construction entities with function for a user
activity
– Technical systems can be subdivided into several
levels of composition, where elements in a higher
level may consist of elements in a lower level.
•
Technical solution: a determined composition of
construction elements.
– A general technical solution has determined
construction elements in a higher level of
composition, while elements in a lower level are
undetermined.
– In a detailed technical solution also elements in a
lower level are determined.
– Construction elements in a detailed technical
solution may also be determined according to
manufacture and assembly.

Technical system is an important
addition realtive to ISO/FDIS 12006-2

It is not necessary to assume a thickness for the Road construction to determine
construction elements in the general technical solution, surface profile is enough.

– boards and wood studs or wood-based framing
27.C/42 Loadbearing external walls - boards and
wood studs or wood-based framing
44.C In situ finishing covering on walls
In the BSAB-system an external wall as a whole is not a class, but its constituents are
construction elements (i.e. design is not supported fully)
An external wall is one (1) class i the new systematic
In BSAB 96 internal walls belong to different classes depending on if they are load-bearing or
non-load-bearing.
This application hinders the use in digital models, where load-bearing is seen as a property of
a wall rather than as class distinguishing.

Construction elements i several composition levels may be objects, e.g. ”External covering” in
an external wall in a BIM.
Production results specifying material and work of an element can be handled as properties.
Designed element according to the earlier standard is a construction element with
determined work results.

Classes in BIM-applications

In conjunction with BIM instances (information
objects) are created from schema classes, such
as interior wall created with the wall tool. The
instance is thus by definition a wall.
The BIM application's tool classes are geometry
objects; their classification as construction
objects must be listed separately as a property.
In practice, the BIM object "slab" can be used
to create, besides slab, a table top, a ceiling,
and an inner floor.
In quantity calculation with BIM the designated
classification is used in stead of instance class.
In a BIM application for design the tool classes
should be construction elements in general
technical solutions that will enable the
determination of construction elements and
characteristics in more detailed technical
solutions.
