So, this was mitigation for a new build, rather than digging features around an existing "used" one, then? It definitely sounds like a poorly-assessed design (esp with the ad-hoc change)... But if it was for a new build, were you at least offered the chance to mitigate the full footprint? I certainly wouldn't work around a used one - at least until it had a few centuries of biodegrading under its belt!
