vibration isolation

Selecting and specifying mounts

Independent. Practical. Precise.

how building services work runs

Building services can cause internal noise, external noise and structure-borne vibration if acoustic requirements are left too late. Setting suitable criteria and reviewing attenuation and isolation during design reduces the risk of expensive remedial work.

review criteria & plant

Agreeing appropriate internal and external noise criteria, then reviewing the available plant and system information.

attenuation & isolation design

Advising on attenuation, breakout treatment, enclosures, screening and vibration isolation where required.

commissioning checks

Undertaking commissioning measurements where included in the scope, and comparing installed performance with the agreed criteria.

Independent. Practical. Precise.

Address plant noise during design, before it becomes a handover problem
