THE BRIEF

Complete Compliance - SAP -Water - Air - Vent - Surrey

THE PROCESS

  • The initial Air Tests carried out were problematic - we carried out some diagnostics with the customer and located the root of the problem in an air leakage point which was sealed up
  •  The initial Ventilation Tests were also troublesome - more diagnostics were conducted and we discovered the length of the flexy ducting was too long and this was causing unwanted trapped air 
  •  We shortened all the flexy ducting to enable all the vents to extract the correct amount of air in litres per second
