G17 Design, Approval & Appraisal

The G17 management procedure details and provides a structured framework for the management and control of new works, modifications and repairs undertaken on gas systems.

The design cycle is broken down into several distinct key stages: initiation, design development, design approval, design appraisal, user acceptance, installation, inspection/testing, commissioning and records completion.

For each design, independent competent persons are used to approve and appraise the works. The approver/appraiser, who must be registered on the nationwide Cadent database, has to have extensive, recent and relevant experience of statutory requirements and NGG codes of practice/operations.

Simkiss have been adhering and designing to this system for numerous years throughout the gas sector. We employ a full team of Cadent design engineers and in-house registered approvers/appraisers to ensure detailed, quality, compliant design packages are generated. From these packages the works are then installed on site, using our team of registered installers, to the satisfaction of the client.
