he timber cladding has been specified but the final
selection of the timber is left to the contractor,
including the visible timber boarding that is specified.
To ensure that this is produced to the appropriate
quality, the architect has required that this aspect
be concluded prior to the Building Contract being
finalised. This enables the contractors that are
•The architect is retaining design responsibility for a
number of cladding elements and these elements have
not been highlighted for inclusion in the Contractor’s
Designed Portion of the traditional JCT Building Contract
being used. The following points are noted:
•The Building Contract has been awarded and the
contractor has already confirmed the specialist
subcontractors that will be used. The matrix has been
updated to include these companies.
Figure 7.3 is not representative of all of the elements of a
small project but provides sufficient examples and notes to
clarify how the Design Responsibility Matrix should be
completed. From this limited worked example of a Design
Responsibility Matrix, updated during Stage 4, the following
points can be observed:
•In summary, the architect has specified the external cladding
aspects in a manner that allows the contractor to provide
alternative proposals for a number of items, giving the
contractor the possibility of gaining a competitive edge
while ensuring that any visible aspects are agreed prior
to the Building Contract being awarded.

should these prove unacceptable, for the cost of any
alternatives to be factored into the tender appraisal.
— The render element is performance specified and the
contractor therefore takes responsibility for this item.
— A number of timber window systems have been sourced
and deemed to be acceptable. These are listed in the
specification; however, the windows are specified in a
generic manner, allowing the contractor to be responsible
for the final selection and to put forward alternative
proposals in the tender submission if appropriate.
— Due to the technical complexity and the need to finalise
supports, etc., the folding aluminium doors have been
specified as proprietary products. The schedule reflects
the fact that, while the architect retains design
responsibility, fabrication drawings are expected to be
submitted by the specialist subcontractor for approval.
