Insurance service organization(ISO) Insurance service organization(ISO) chicopee (Mechanical) (OP) 14 Feb 17 02:39 ISO used to keep records of sprinklered properties, is that still being done by this organization? RE: Insurance service organization(ISO) cdafd (Specifier/Regulator) 14 Feb 17 14:01 I want to say yes. They seem to know which buildings in our city have/had sprinklers. Were you going to ask them for a list,,, for a particular city??? RE: Insurance service organization(ISO) chicopee (Mechanical) (OP) 20 Feb 17 16:43 There may be a request but my understanding is that sprinklered plans are only available to insurance companies. RE: Insurance service organization(ISO) LCREP (Specifier/Regulator) 20 Feb 17 17:23 And not all insurance companies only member companies can access that data. RE: Insurance service organization(ISO) cdafd (Specifier/Regulator) 20 Feb 17 17:42 I have not heard of insurance companies keeping fire sprinkler plans, unless they have a hand in design and insuring possibly. Some cities retain plans. Why the question RE: Insurance service organization(ISO) LCREP (Specifier/Regulator) 20 Feb 17 18:02 Cd If the building owner wants a reduction in insurance premiums the plans would need to be sent to ISO. Since the insurance company, Chubb I worked for was not a member of ISO we did not use ISO building rates, we used our own rates. Most large insurance companies do not use the ISO rating system. At one time if ISO did not witness the annual main drain test they would withdraw the sprinklered rate. I have been out of the loop since 2015 when I retired and do not know if this is still being done. RE: Insurance service organization(ISO) cdafd (Specifier/Regulator) 20 Feb 17 21:55 Thanks RE: Insurance service organization(ISO) amedik1 (Specifier/Regulator) 23 Feb 17 16:44 ISO/Verisk is only aware of sprinklered buildings within a jurisdiction, when they have physically visited the building on the behalf of an insurance carrier (or did the plan review). Many of the larger insurance companies have their own engineering field staffs (examples include; FM, XL GAPS, Zurich, AIG, etc.) Not all insurance carriers utilize ISO services or information. They have a group that does the sprinklered building evaluations, and a separate group that does the municipal rating system. As for premium rate increases / or reductions, the plans should be sent to whom the insurance carrier uses, and this could be either the insurance carrier's engineering group, or ISO. If the insurance carrier does not utilize ISO's rate structure or services, you gain nothing with one's current carrier by sending the plans to ISO.
