RE: Andersen Office Complex Fire Review (The old St. Croix Mall)

I've been reviewin the old St. Croix Mall fire protection prints sense Andersen Corporation purchased the
propert The fire protection class chan from a Group M Occupancies (Mercantile) to a Group B
Occupancies (Businesses). The sprinkler densit is g reater in a Group M than the Group B. With Herber
still on the East side of the mall there is a mixed g roup class. Herber is still in a Group M. There are no
special fire separation re for an M to a B.
This fire sprinkler s is desi in what we call a pipe schedule s This is a fire protection
sprinkler s that is based off of the number of heads, distance to the main, water main pressure, and
re sprinkler densit The new fire protection sprinkler s are based off of the same criteria but
with a computer pro The pipe schedule s have a hi level of safet factor built into the
calculations. The mall sprinkler s is still based off a Group M sprinkler densit and a pipe-schedule
s which is well above the re densit f actor for the sprinklers if the Mall.was to be built toda
as an off ice buildin a Group B. It is sprinkled above and below all the ceilin a re do to the
open area between the suspended ceilin
All the sprinkler risers are monitored for water flow and all air handlin units have smoke detection. The
buildin is divided into 10 sprinkler zones and 5 fire department connections. There is a fire h within
the re distance to each fire department location.
The one open issue is the location of fire h on the propert and the water main pipe size. Andersen
Corporation has reviewed with me the construction prints and pipe sizes on the print. B the prints there are
3 water mains comin into the buildin (2) 8" water mains comin from Os and (1) 8" water main
comin from 60th street. There is g ood fire h spacin except for the North side of the buildin There is
no h between the h on Omaha Ave. and the h in front of Herber on the North side.
Based off the sprinkler s the buildin fire loadin the buildin usa as a Group B, and the
locations of emer exits and li I don't see a life safet problem. Therefore I'm not re the
Andersen Corporation to add an additional h at this time.
