The Fire Sprinkler Certification Process What prevents certification? Matt McLellan Aon Sprinkler Certification October 2014

Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential 1 What prevents certification? This presentation is intended to help explain some of the requirements around information required to certify and close out projects and hopefully make the process smoother for all involved? Look at varying requirements for different project types. Different project stages. Information from various parties. In order to avoid this………………
3
Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential 2 Project Type Three broad project categories: New installations. Extensions to existing installations. Alterations (including water supply changes).
4
New Installation Documentation (pre construction) Design parameter application (Form 1) – the other comments section provides scope to clarify anything unusual in the design Storage protection supplement (Form 1a) Storage declaration (critical component for warehousing etc) Clear block plan and cross section Fire Report (consent version) Water supply information (current flow test) Pump details and tank (if applicable) Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
5
Extensions (some unique requirements) Copy of the current biennial / annual survey (overall condition of system) Fire Report requirements for extensions adopting superseded standards Is certification required for the existing installation as well? (can get involved if existing system has never been certified) Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
6
Alterations (unique requirements) Same need for survey and fire report etc Water supply upgrades need all documentation pertaining to proposed supply and any addition of pumps / tanks Internal alterations need an application if over certain limits (refer SNZ FI- 100 if in doubt) Alterations can get confusing – as shown!

7
Design Stage – potential problems Designing to a superseded standard (logical in some cases, but not in others – ie, EPS building to 1987 Standard) Confirming NZBC modified or not – not always obvious Out of date water supply information, many councils are adopting / investigating pressure reduction to reduce leakage and maintenance costs Pump information – need both the pump curve and engine power curve Water supply tanks – need drawings to confirm volume and producer statements for the tank and foundation design Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
8
Design Stage – potential problems Making sure the client understands what they are going to store – idle pallets don’t mean no storage in the context of a sprinkler system. Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
9
Design Stage – potential problems Omission of sprinklers in various areas (ie, server rooms / transformer rooms) Water supply connections ‘by others’, can cause problems with metering, valving etc. Freeze protection – refer Appendix L for ‘guidance’…………… Preferable to close out design review queries early! Provisions to be able to successfully flow test (high flows will easily cause damage) Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
10
Design Stage Landscaping in front of the FSI is not the best idea Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
11
Construction Stage Installer typically / historically will engage the inspection provider Inspection needs to be timely, difficult for all concerned if linings are complete by the time of inspection First fix needs to be able to review ceiling space pipe work, sprinkler coverage, fire separations, flexible dropper assembly installation etc Tenancy fit outs can introduce more onerous protection requirements Significant design changes should be communicated to SSC Seismic design - inspection company will review Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
12
Construction Stage External fire loads can often be a surprise (NZBC does not delete ‘other exposures’ covered in NZS4541:2013 clause 206 – but standard now has guidance) Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
13
Completion Documentation (from installer) Form 1 (Signed completion statement / producer statement) Asbuilt drawings and block plan (including asbuilt flow testing) Hydraulic calculations (including a clear node diagram) Flexible dropper allowances need to be quantified against data sheet Pressure test certificates for dry systems, FSI’s and underground pipe work etc Flushing evidence for underground pipe work Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
14
Completion Documentation (from installer) Inspection company sign off (IANZ endorsed sign off report – need more than the traditional ‘letter to connect’) Producer statements for tank and foundation construction Confirmation of NZFS connection Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
15
Completion Documentation (Inspection Company) Sign off reporting (IANZ endorsed) Full flow testing information (complete information if pumps are included) Testing of tank infill rates to provide adequate evidence of an acceptable water supply duration Inspection company may have comments in regards to any items raised at design review Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
16
Other Issues Diesel engine speed control on pump boosted towns main supplies Test return arrangements to date are not letting the pump run under full load on the weekly test (often only a fast idle) NZS4541:2013 clause 607.3.4.2 gives guidance on arrangements to achieve weekly testing at full engine speed / load, new clause that has not been readily adopted yet Site water supplies Recent projects have had trouble achieving compliance due to the site reticulation not being coordinated with fire sprinkler requirements Valving and hydrant arrangements have been the typical problems Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
17
Other Issues All parties need to be clear in regard to scope of certification (ie – base build only etc) Certification of old systems From time to time it is requested that an old system be certified or recertified This is readily achievable if evidence of previous certification is available If not it is more involved and will effectively require the information that would be supplied for a new installation This has been an issue recently, with some councils requiring site wide certification at the time of relatively minor alterations / extensions Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
18
Questions / Comments The preceding content has been intended to assist in the process of achieving compliance / certification for sprinkler projects, we trust it has been of some assistance. Aon Risk Solutions | Global Risk Consulting Proprietary & Confidential
