RE: Fire Flow Addendum for EDI Expansion
Dear Kevin:
We have submitted a building expansion plan for the St. Joseph EDI Expansion located at 4411
State Highway 6 South. This building expansion is being proposed to add 1,396 square feet to
the existing building in an effort to increase the number of exam rooms offered within the facility.
An original fire flow report was prepared for this project on September 8, 2008 with addendums
prepared on October 31, 2008 and August 24, 2009. As seen in the October 2008 report, fire
flows were run for both the EDI as well as the adjacent Medical Office Building (MOB). The
required fire flow and subsequent runs were based upon the MOB fire flows as it was higher
than those required for the EDI. In that report the EDI was estimated as follows:
• Building Type = Type IIB construction
• Building Size = 15,000 square feet
• Required fire flow = 2500 gpm
• Required fire flow with 50% reduction for sprinkler system = 1250 gpm
With the additional 1,396 square feet the totals for fire flow calculations are as follows:
• Building Type = Type IIB construction
• Building Size = 16,396 square feet
• Required fire flow = 2750 gpm
• Required fire flow with 50% reduction for sprinkler system = 1375 gpm

As seen in the calculations above, the fire flow requirement does increase slightly, however as
stated in the October 2008 report the EDI was not the critical building in the fire flow analysis.
The MOB building required a much higher fire flow at 1500 gpm. This is still the case and the
analysis completed in 2008 showed that the waterlines and fire hydrants as designed were able
to meet the 1500 gpm fire flow for that building. Therefore they would also be able to meet the
1375 gpm fire flow for this EDI expansion. Please call if I can answer any additional questions.
Sincerely,
