The online magazine BUILDING provides very useful CPD to the construction sector -and sometimes this has some valuable cross-over with archaeology.
One of their latest courses, CPD12 2018: Joint Contracts Tribunal, provides a very useful guide to the forms of contract that are frequently used to procure archaeology.
You’ll need some background in this already to get the most from it, but it should make useful reading for project managers. You can also take a test and secure some valuable CPD points and a certificate.
The online course can be taken here (ignore the deadline date)
