Gas protection measures, particularly the membranes used to protect buildings from the effects of harmful ground gases, are only as good as their installation. Quality installation requires knowledge and expertise in those individuals conducting the work and the BGA has been pivotal in developing the training of installation technicians in the sector. Quality assurance of such work is the final piece of the jigsaw and with clients and regulators increasingly asking for verification to be carried out on installations it is important that those charged with this important duty are competent and experienced.

therefore have the opportunity to see, in controlled conditions, the difficulties encountered by installation technicians, and learn how to ensure that they are overcome. There will also be a day of supervised site inspection on a live project.

Successful candidates will be issued with a certificate of competence jointly awarded by the BGA and CITB (Construction Skills)

Fees

3 day course plus 1 day supervised assessment.

Assessment 4
Candidates to carry out supervised site inspection on live projects and submit Verification Report within 12 weeks of attending course. For candidates not already employed in this area of work the instructors will arrange for candidates to attend projects that the instructors have been employed to carry out. All candidates must have a valid CSCS card prior to attending any site inspections.

Course information

Modules have been developed to introduce the candidate to the occupational competencies required for the verification of the gas membranes and systems used within the industry.

The modules focus on the use and application of underpinning knowledge along with practical skills and will enhance the awareness of approved procedures to carry out verification and testing of gas membranes.

Outcome of the course

The candidates will be issued with a certificate of competence jointly awarded by the British Geomembrane Association and CSkills only after successful completion of all 4 assessments. Candidates will be able to re-submit assessments up to 4 times in any calendar year and re-attend modules 4-8 free of charge on one subsequent occasion should further training be necessary to pass the assessments.

Verification and Integrity Testing course

The new Ciria C735 Guide, now published, details the recommendations for this hitherto deregulated area, describes the main methods of verification and integrity testing, and explains when and how these tools should be used.

The BGA is pleased to have been involved in the development of a training course for verification professionals and, in conjunction with the CITB, is offering this course to existing practitioners or those wishing to engage in this sector.

The course is run over three days in a practical classroom environment at the training centre in Doncaster where the NVQ level 2 specialist upskilling is run. You will
