Not your usual NFPA question but it does have something to do with fire sprinklers and NFPA standards.
I know we have a number of insurance company people here and I would like to have an idea fire sprinklers have on insurance rates especially for storage facilities and Extra Hazard production areas.
About 30 years ago I remember giving a proposal to install sprinklers in an existing 30,000 sq ft metal building which was used to manufacture plastic parts using extrusion molding with machines that had a lot of hydraulic oil. Going on memory the building was insured for $10 million (1988 dollars) at a rate of $1.20 per $100 or 1.2% which gave annual premiums of $120,000.
The owner told me the sprinklered rate for the building would be reduced to $0.25/$100.
Seeing as how the sprinkler proposal was $40,000 it came as a no brainer as there would be a 100% return on investment in six months. We got the contract and the owner couldn't wait for the installation.
What are today's rates for sprinklered vs unsprinklered buildings?
Let's say I have a 200,000 sq ft warehouse with 20' rack storage of exposed Group A plastics and while the building does have sprinklers it's an older OH pipe schedule system installed between 45 and 50 years ago.
Peak of the building is 30' with a 6" riser having a city supply of 60 static, 40 residual flowing 1,600 gpm at the street. Doing the calculations and it isn't good.
The value of the product, totally guessing here, has to be at least $30 million and I could see $50 million especially if we have business interruption insurance enter the picture.
What affect would upgrading the system to an ESFR using K16.8 pendent heads per NFPA #13 have on the insurance rate?
