We were contracted to do a few add/relocates on an existing concrete tee
construction facility.  A flag was thrown up once we found out what was
being installed for this tenants flooring.  They are using an astro turf
type field.  The problem isn't with the turf itself.  It has undergone
extensive testing to prove that it is not flammable.  The problem is with
the inlay.  They have used the type of inlay you would see on an outdoor
facility which is ground up tires.  I have checked with the plant manager
who supplied their product and they do not use any type of a fire proofing
spray on the product.  Essentially it is ground up tires.  We have a deck
height of approximately 16 feet and it is double tee concrete construction.
The fire marshal and my concern is that the existing sprinkler system can
not handle this type of fire.  I have already calced it and the best the
system could do is a .2/1500.  This gives a 13 lb safety.  Has anybody dealt
with anything close to this on an indoor facility and should we be concerned
with this inlay?  Thanks in advance.
