Admittedly, I’m not an expert on calculating delay damages or navigating delay claims – and I’m not sure I’ll be able to help you with your assignment. But, I can help explain some basics on concurrent delays:

When a delay is concurrent with some other delay, that means the delays overlap – at least to some extent. So, if a secondary delay happens to occur at the same time as a delay that happened earlier, that secondary delay won’t always be fully compensable.

For example: If A’s work is delayed due to B’s action, typically, A may be compensated in some way. If C’s work is delayed for some independent reason, then C can normally be compensated for the delay.

That is, unless the delays are “concurrent”.

If C’s delay falls partially or wholly in line with the delay A also suffered, then C’s delay might not be compensable (or fully compensable) since it happens to overlap with A’s delay.

I hope that was helpful – and good luck with your assignment!
