Contact us: operationssupport@nhbc.co.uk11.3.4 Structural design checking and certification
Design of the superstructure shall be adequately checked by an appropriate NHBC registered volumetric frame certifier.
Homes with a volumetric frame superstructure require certification confirming that the design has been checked by an NHBC registered volumetric frame certifier.
The certifier should:
- be listed on NHBC’s list of volumetric frame certifiers
- be a suitably qualified civil or structural engineer with relevant experience in volumetric construction
- not be the designer of the volumetric frame or be employed by the same practice
- check supporting details and calculations
- complete and sign a certificate confirming assessment of structural adequacy for each specific project
- provide the registered builder with the completed and signed certificate.
The registered builder should ensure that the completed certificate is available on site for inspection by NHBC.
