On the same subject, the Council of American Structural
Engineers (CASE) provides a more detailed explanation of the
engineer's roles on a building project. It can be assumed that
the roles described will be applicable to engineering design
worldwide. According to the CASE website:
A Specialty Structural Engineer (SSE) performs structural
engineering functions necessary for the structure to be com-
pleted and is someone who has shown experience and/or train-
ing in the specific specialty. The SSE is usually retained by
a supplier or subcontractor who is responsible for the design,
fabrication, and (sometimes) installation of engineered elem-
ents or by the general contractor or subcontractor(s) respon-
sible for construction related services. Common examples of
such elements are precast or tilt-up concrete, open web steel
joists, pre-engineered cold-formed steel or wood trusses, and
metal building systems.
The Structural Engineer of Record (SER) perform[s] or
supervise[s] the analysis, design, and document preparation
for the building structure and has knowledge of the require-
ments for the load carrying structural system. The SER is
responsible for the design of the primary structural system,
which is the completed combination of elements which serve
to support the buildings self-weight, the applicable live load
which is based upon the occupancy and use of the spaces,
[and] the environmental loads such as wind, seismic, and
thermal.
The CASE website goes on to explain that every project
should have a single designated SER who establishes the struc-
tural design criteria and concepts for the project, consistent
with the role described in the UK codes. The SER may delegate
