THE BRIEF

We completed a SAP Assessment and Full Building Testing for this property in London

The Building Testing included New Build Air Testing, Ventilation Testing and we also did a test for sound which is called a Sound Insulation Test
Building Certification included a SAP Assessment and we also completed Water Usage Calculations
The Sound Test was an Airborne Wall test

To pass an Airborne test for new build properties you must score 45db or higher
Airborne tests measure the difference in sound levels between the receiver room and neighbouring walls or floors
If the sound output in the receiver room is 100db and the sound leakage being passed through into the neighbouring room is 40db, then the result would be 60 and therefore would be a pass

THE PROCESS

After reviewing drawings, on site testing was ready to be completed. In accordance with our strict air tightness testing procedure and sound testing procedure, all calibrated equipment was setup to ensure the most accurate result possible
This was a very modern building where we had to check the building specification carefully to ensure it was feasible
Our consultants guided the customer to ensure compliance was met
