Design new or replacement gas systems, installations and components for industrial and commercial properties and leisure accommodation

This standard is about designing new or replacement gas systems, installations and components for industrial or commercial properties or leisure accommodation.  It is for the non-residential part of the downstream gas industry.  It can apply to gas systems, installations and components for any type of fuel gas or combinations of fuel gas.

It includes interpreting job requirements, identifying conflicting issues, carrying out design calculations, complying with statutory, industry and manufacturers’ standards presenting design options and agreeing and documenting final designs.

This standard is for those designing new or replacement gas systems in non-residential downstream, industrial or commercial properties or leisure accommodation.

1. identify and record customers’ job requirements from relevant sources of information

2. identify any conflicting issues between customers’ job requirements and statutory, industry and manufacturers’ standards 

3. identify any key structural features that could affect designs 

4. ensure that proposed siting of system components meet manufacturers’ and industry standards’ 

5. confirm that new or existing fuel gas services are available and suitable

6. confirm and verify that proposed gas systems, installations and components will not conflict with other existing or proposed electrical, water or ventilation systems 

7. carry out design calculations to determine gas system components that take account of the volume of gas required

8. design gas systems, installations and components to meet key design requirements

9. check that designs are in compliance with statutory, industry and manufacturers’ standards

10. prepare a range of design options to meet both customer and industry requirements

11. present design options to customers in sufficient detail for them to be able to assess them 

12. suggest and agree viable alternatives with customers when their job requirements cannot be met

13. obtain and record agreement to design options that best meet all requirements

14. document agreed designs in sufficient detail for them to be installed by others

1. regulations and guidance governing health and safety in the workplace, environmental protection and the use of risk assessments

2. legislation covering the general responsibilities of the operative for their own safety and that of others

3. site considerations including transport, movement and positioning of components on site, safe accessibility to work activities, working at heights, or in confined spaces

4. construction materials and methods for installation of gas systems, installations and components

5. methods of working which protect the building, customer property, new and existing systems and components

6. how to survey work sites 

7. how to read and interpret site diagrams 

8. how to confirm the suitability and availability of new or existing gas input services 

9. the implications on designs of dual fuel gas systems

10. sources of information about other electrical, water or ventilation systems that may have an impact on gas system, installations and components including electricity, water, waste water, ventilation, flue/extraction systems and fresh air systems 

11. where to access and how to interpret required information including statutory and normative documents, industry standards, guidance documents and manufacturers’ instructions.

12. how to ensure design proposals for gas systems, installations and components meet all required industry standards

13. the impact of local and regional gas pressure on system, installation and component design 

14. the range and operation of gas systems, installations and components

15. how to design new and replacement gas systems, installations and components

16. how to use information technology to produce drawings and specifications

17. how to present design options to customers including written, oral, electronic and drawings

18. forms of recording customer agreement
