| Retained by a Council to use expertise in dealing with low frequency noise and ground borne vibration due to a textile factory:
NVM proposed a scope of work that involved surveys in the affected residential property and then tests with noise measurement investigations at the factory to ascertain the paths for the nuisance. With reference to BS4142, the complaints were justified. Best practicable means were deemed to be available.
Requested by a North-West City Council to monitor vibration due to construction site compaction:
A large retail development on made-up ground where large-scale consolidation was needed, NVM provided specialist noise measurement and vibration monitoring within a permanent showman's mobile home encampment and advice to the Council regarding scale of vibration and amelioration.
