- Drawing reviews: Design and/or construction drawings reviewed and commented on identifying potential building envelope leakage paths.
- Pre-test Site Inspection: Undertaken at various stages during the construction.
- Fault Finding – Visual inspection, Smoke Testing and Thermographic Surveys can be undertaken to determine key leakage paths.
- Training seminars: Aimed at Architects, Engineers and Project Managers, Build Check offer a 1 hour Power Point presentation which may be used to contribute towards CPD points required for membership of professional institutions.
- Site training/induction seminars: One effective method to reduce leakage rates is for on-site seminars to be carried out for the construction team. Build Check carry out such seminars and strongly recommend that a training programme is allowed for on all large projects.
