introductory document we call this the ‘Technical Stage’
be thinking, ‘do I need building regulation drawings’?
projects, in short, yes you do. Why? Because, the design should be checked by
an approved inspector before works start to make sure you and your builder are
independent building inspector will take approximately 2 weeks to complete the
plan check following registration of the application.
- Technical Plans, showing the location of any:
- Technical Sections
- Building Regulation Specification
- drawing upon relevant building regulation which is appropriate for the project.
- Liaising with Inspector until Plan Check Approval
- Dimensions and lengths of members for fabrication or manufacture.
- Party wall matters or agreeing position of party walls or boundaries.
- Design of bespoke items such as staircase.
- Design of precast concrete, roof trusses, glass structures or items of specialist manufacture.
- Detailing of piled or reinforced foundations. An assumed bearing pressure will be used and will need to be confirmed when construction starts on site.
- Temporary works design. These allow the permanent works to be installed is normally carried out by the contractor.
Buildings and Structures
and altering existing buildings and structures have their individual
challenges. The most noteworthy of these challenges is ascertaining the
existing structural elements and building fabric. Working with older structures
often require assumptions to be made for the implementation of new structures.
the construction, any assumptions made at the design stage need to be to verify
that the design is valid. In an ideal project, the structure would be exposed before
any design work begins.
is dependent upon occupation and timescales. In most instances, full exposure
of the structure is not feasible.
Tier 1 (standard) – An inspection of
elements of structure which are available and a check on span of floors, roof
and beams that are exposed. This type of survey enables a design based on the
information obtained from similar buildings or structure types, historical data
and available structure.
of assessment will require any assumptions made to be confirmed by the
contractor once the structure is exposed.
the possibility of unexpected elements such as flues will be discovered. It is
a good idea to allow for cost variations due to any unforeseen elements.
Tier 2 (optional)– Partial removal to
expose the structure. This needs to be carried out at critical locations to
establish which walls are load bearing, locate columns, beams and check floor
spans. This type of investigation reduces the number of unknown factors which
affect the design but there is still the possibility of unexpected elements
being uncovered during the construction phase.
Tier 3 (optional)– Complete removal of
finishes to expose existing structure. This type of investigation reduces the unknowns
and therefore provides the greatest cost certainty during construction.
