Other purpose of this document is to highlight that the list of items in schedule 3 is not intended as (or sufficient for) a scoping exercise. Other purpose of this document is to highlight that the list of items in schedule 3 is not intended as (or sufficient for) a scoping exercise. Which leads on to the biggest single issue with the operation of the scheme:

7. What are you certifying ? It is important that we ALL understand this: a)When signing / receiving certificates b)At the end of the project c)Part way through a project when multiple certificates are being issued d)When auditing We ALL need to be clear on this, and have the same understanding of the situation, at any point in time. We can only achieve that through scoping, planning, care and clarity in wording on certificates.

8. Changes to certificates Tweaks to wording on certificate Box to identify: Initial, or interim certificate Initial, or interim certificate Final Certificate Final Certificate Amendment to certificate Amendment to certificate All certificates on a projects should be produced by the one certifier – if that is not the case the new certifier has to review, and take responsibility for, the design of the entire project.

9. What are you certifying ? The design of: a)The elements listed in schedule 3 ? b)The elements shown on your own drawings ? c)The building structure ? d)The design of the elements in the drawings listed in schedule 1 ? e)The design of all elements, except those listed in schedule 2 ? f)The design of the building ?

10. Certification Plans - Scoping To ensure you have identified and dealt with all of the relevant building elements you need to set about the task in a methodical and thorough manner. To ensure you have identified and dealt with all of the relevant building elements you need to set about the task in a methodical and thorough manner. All the relevant items should be identified prior to the first certificate and a plan to obtain the necessary information put in place. All the relevant items should be identified prior to the first certificate and a plan to obtain the necessary information put in place. The list of items in schedule 2 should then decrease as further certificates are issued. The list of items in schedule 2 should then decrease as further certificates are issued. Yes client changes may lead to other elements being generated but CP should be a live and developing document.

11. Scoping Check List We dont want to issue scoping check lists as: Each project is different. Each project is different. Check lists are a useful aide memoir but dont replace scrutiny of the project. Check lists are a useful aide memoir but dont replace scrutiny of the project. The certifier must assess each project, determine what is relevant and plan his actions, and the information flow, accordingly. The certifier must assess each project, determine what is relevant and plan his actions, and the information flow, accordingly. GN2 Appendix and Audit Guide give a useful start - GN2 Appendix and Audit Guide give a useful start - BUT it is your own experience and judgement which is the best route to adequate scoping.

12. So What else should the Certification Plan Contain ? Certification plan is also a good place to record and/or prompt you to consider: a)Level of checking required. b)Information considered ( Drawings, calculations, reports, specifications etc – and who is responsible for supplying). c)Designer(s) and checker(s). d)Design Codes. e)SI requirements. f)Disproportionate collapse. g)Conversions – what considered. Check Lists are a good aide-memoir but must still consider each project on its own merits.

13. TB4 Certifying Structural Design of Conservatories Conservatories area problem because in England you can build a conservatory up to 35m2 without a building warrant – that is the biggest market for the manufacturers. Bye Laws definition of a conservatory Bye Laws definition of a conservatory Small conservatories (<20m2) at ground floor level built as extensions exempt from bye law requirements. Small conservatories (<20m2) at ground floor level built as extensions exempt from bye law requirements. If built at time of main house MAY still be exempt – depending on Thermal separation.

14. TB4 Certifying Structural Design of Conservatories Where test certificates provided for component: a)Pay particular attention to connections b)Racking stability c)Uplift d)Possible need for ties to prevent eaves spreading In all cases where BBA certificates used in place of calculations need to pay particular attention to design codes, and wind loads and snow loads – are these sufficient for your project ?

15. TB4 Certifying Structural Design of Conservatories Role of certifier is to confirm: That the structure has been designed to be stable under appropriate loads. That the structure has been designed to be stable under appropriate loads. That the design of Individual members can be substantiated by test or calculation.

17. TB5 Certifying the Design of Protective Barriers Risk Based approach to certification: Traditional domestic with no long balconies and limited risk to occupants – specification to BS585 may be sufficient. Traditional domestic with no long balconies and limited risk to occupants – specification to BS585 may be sufficient. On larger projects – mezzanine floors, longer spanning stairs, balconies etc adequacy must be assured by calculation or test. On larger projects – mezzanine floors, longer spanning stairs, balconies etc adequacy must be assured by calculation or test. Freestanding Glass Barriers BS6180 – quite stringent requirements.

21. Issues determining Level of Risk 1.The inclination of the element (vertical/horizontal/inclined). 2.Size of the glazing element (frame). 3.Size of a single pane. 4.Height of glazing above ground level. 5.Does the glazing form a barrier ?. 6.Ownership/public access to land immediately outside building.

24. High Risk Building / glazing which falls outwith the range of BS6262 or BS 5516 OR Any point fixed glazing systems OR Any innovative glazing systems or design approaches

25. Certification of Low Risk Glazing The certifier must ensure that the glazing elements, (panes, frames and fixings) are specified to comply with BS6262:2005 and/or BS5616:2004 in the drawings submitted with the design certificate. The certifier must ensure that the glazing elements, (panes, frames and fixings) are specified to comply with BS6262:2005 and/or BS5616:2004 in the drawings submitted with the design certificate. No further design substantiation will normally be required and certificates can be signed off on the basis of relevant standards having been specified on the plans specification listed on the design certificate.

27. Certification of High Risk Glazing Most certifiers will have insufficient experience to be able to design these elements an in such circumstances the advice of an acknowledged expert should be sought, either to carry out, or confirm, the design. In these circumstances the certifier should: satisfy himself of the relevant expertise of the expert. satisfy himself of the relevant expertise of the expert. satisfy himself that the design has been checked by a suitably experienced individual. satisfy himself that the design has been checked by a suitably experienced individual. obtain copies of the suppliers/manufacturers design calculations. obtain copies of the suppliers/manufacturers design calculations. ensure that the design has been carried out to the relevant standards and loadings. ensure that the design has been carried out to the relevant standards and loadings. satisfy himself that the design is compatible with that of the supporting elements of the building. satisfy himself that the design is compatible with that of the supporting elements of the building. record that these elements have been certified using Option 4 (SER GN2) in Schedule 3 of the certificate. record that these elements have been certified using Option 4 (SER GN2) in Schedule 3 of the certificate.

28. Acceptance of Test Results Alternatively suitable accredited test results, which are appropriate to the panel size, aspect ratio and loading of the elements under consideration, may be accepted in the place of design calculations. - but dont forget glazing comprises glass, frame and the fixings back to the main cladding/structure. - but dont forget glazing comprises glass, frame and the fixings back to the main cladding/structure.
