Answered: NEC3 ECC: Early warning notices on the revised Programme

My slant as to whether the Contractor should show an early warning on a programme depends on the likelihood of it occurring :
- if it's 10%, the answers almost certainly not;
- if above 80%, the answer is is almost certainly 'yes';
- somewhere in between : have a discussion about it and what you are going to do about it i.e. a risk reduction meeting and then decide based on some established protocols
