There is case law
which suggests an architect or engineer has an ongoing duty to review their design.
The architect is under a
continuing duty to check that his design will work in practice and to correct
any errors which may emerge. It savours
of the ridiculous for the architect to be able to say: ‘True, my design was
faulty but of course, I saw to it that the contractors followed it faithfully’
and to be enabled on that ground to succeed in the action.[1]
There is authority that duration of the duty
continues beyond practical completion until the works are truly complete.[2]
