Assembling A Collaborative Team - Other - Page 82
This reference is derived from the elements table (EE) of
Uniclass 2.
In some instances, a mixture of levels of design will be
required for an assembly. For example, planning
requirements may dictate that the brickwork and window
components are specified as full: proprietary whereas the
‘non-visible’ aspects, such as lintels or the inner leaf
construction and insulation, are specified as full: generic,
allowing best value products to be sourced and proposed
by the contractor and the specialist subcontractor.
Outline (Out): This level of design should be sufficient to
enable the client to sign off the proposals and to allow the
appropriate Cost Information to be produced.
Performance (P): The design is progressed on a performance
basis with the specialist subcontractor developing the
design in accordance with the performance criteria set out.
The geometric information should be developed accordingly.
Full: generic (F-G): The full design is completed but the
choice of final products is left to the contractor and the
appropriate specialist subcontractor.
Full: proprietary (F-P): The full design is completed and
specific products are specified.
Columns 4, 7 and 10Level of Design (LOD): the column clarifies the Level of
Design that will be produced at a given stage. While the
terms are primarily specification orientated, it is expected
that the level of detail in any 2D or 3D geometric information
in the Information Exchanges will reflect the Level of Design
that is produced. The different levels of design are:
Columns 3, 6 and 9Design Responsibility: this is the party that is responsible
for this aspect of design at this stage.
Column 2This is the element/system of the building for which design
responsibility is being allocated.
Column 1
Function of each column
Column 14The Design Responsibility Matrix cannot deal with the
complexity of the many design interfaces encountered on
a project. To bring further clarity, notes can be added on
certain subjects. Examples of these notes are shown in
the worked examples in Figures 7.2 and 7.3.
Column 12
This column is for use on a JCT traditional form of contract
using the Contractor’s Designed Portion (CDP) to allocate
discrete aspects of the design to the contractor within the
Building Contract. It can be deleted for design and build
or contractor-led forms of procurement.
Column 13This column is for use on larger projects where the client
may wish a warranty (Warr.) to be put in place between one
of the specialist subcontractors and another party. It can
be used for the development of the Building Contract by
stipulating the circumstances in which such warranties
are required.
Columns 5, 8 and 11Information Exchange: this column is used to confirm what
aspects will be included in the Information Exchange at the
end of a stage. It can be used to specify the scale of the 2D
deliverables that will be produced or, by using ‘Yes’ or ‘No’,
to clarify whether information on a particular element will be
included in the geometric aspect of the 2D or 3D models
being produced. This column is primarily associated with
geometric information and it is likely that level of detail
references will be inserted here once these have been
developed in a manner suitable for use industry wide.
