Design meeting with the Project Team on site
  • A review of existing drawings from an air tightness perspective
  • Summarising bullet-point email within 10 working days
  • Targeted at establishing an airtight barrier at an early stage
  • Targeted at minimising the risk of a final air test fail
Design review of architectural drawings
  • A review of up to 30 section detail drawings
  • Report and annotated drawings within 7 working days of booking
  • Targeted at minimising the risk of a final air test fail
  • If working in a portal, relevant drawings to be selected by the client and placed in a folder. All drawings to be in pdf format.
Construction consultancy site inspection with report
  • Monitoring of the airtight barriers construction and identifying leakage paths as they rise during construction
  • Site Pro Report
  • Targeted at minimising the risk of a final air test fail
Pre-test consultancy visit with photographic report
  • With or without pressurisation
  • Identifies possible leakage paths before the final test so allowing time for site to carry out remedial works before the final test
  • Site Pro Report
  • Targeted at minimising the risk of a final air leakage test fail
Final Air Leakage Testing of single buildings
  • Envelope area calculation included
  • To perform an initial air permeability test
  • In the event of a fail, to perform localised smoke testing to identify leakage paths as part of the service
  • After remedial work by site, to perform an additional air permeability test
  • Repeat the process as many times as required or possible within the time allocated on site
  • Sitepro fail report, if required or requested, within 7 working days
  • Declaration of result / certificates within 7 working days
Final Air Leakage Testing of multiple units on a visit
  • Envelope area calculation included
  • To perform an initial air permeability test
  • In the event of a failure, to perform localised smoke testing to identify leakage paths as part of the service
  • After remedial work by site, to perform an additional Whole Building Air Permeability Test before moving on to the next unit
  • Repeat the service on the next unit
  • Sitepro fail report, if required or requested, within 7 working days
  • Declaration of result / certificates within 7 working days
Smoke shaft testing
  • Perform air permeability test
  • In the event of a fail, localized smoke testing to identify leakage paths included
  • After remedial work by site, to perform an additional Air Permeability Test
  • Sitepro fail report, if required or requested, within 7 working days
  • Declaration of result / certificates within 7 working days
