This could be a compensation event under at least two headings :
- 60.1 (1) where the reduced WAs are a new ‘contraint’ so a change to the Works Information; &/or
- 60.1 (2) where you are not allowed access to the Site, where the Site is sub-set of the Working Areas and it is the Site that is being altered.
I could also, depending on the circumstances, be a compensation event under 60.1 (3), (4) or (5).
