Shaping the Future

This design advice does not cover the construction or installation of the works on site. The Builder shall
confirm the adequacy of the site conditions during installation and shall advise the Engineer if variation
from details shown on the drawings occur. No detailed site investigation or studies have been carried
out by us or provided to us. The design review has been carried out on the basis of limited enquiry only.
Pile depths shown are applicable to founding in stiff clay or dense sand. There is some additional risk of
failure should the above design criteria be exceeded, or actual site conditions be inferior to those
assumed. If ground conditions other than those described above are encountered during construction
or seabed levels encountered are deeper than those shown on the drawings, further advice should be
sought.

This design advice relies on designs prepared by other consultants, but does not warrant them.
The structure is to be built in accordance with the following referenced documentation, using good

building practice.
