CHAPTER/SECTION::
Chapter 4 / Section 423.3
PROPOSED TEXT::
423.3 Critical emergency
operations.
In areas where the shelter design wind speed for tornadoes hurricanes
in accordance with Figure 304.2(1 2) of ICC 500 is 250 190
mph or greater on island states or territories where vehicle access to
the continental US by roadway or bridge is not available, 911 call
stations, emergency operations center and fire, rescue, ambulance and police
stations shall comply with Table 1604.5 as a Risk Category IV structure and
shell be provided with a storm shelter constructed in accordance with ICC 500.
REASON/SUBSTANTIATION/BIBLIOGRAPHY::
TheCommonwealth of Puerto Rico is group of islands in the Caribbean that is notconnected via land or roadways/bridges to a larger land mass. When a hurricaneor tropical storm threatens the Commonwealth it is not practicable or feasiblefor all residents to evacuate the territory. This situation presents alife-safety issue for residents of Puerto Rico who do not have a safe place toseek refuge as there are no ICC 500 compliant storm shelters or FEMA P-361 saferooms available for public use at this time in the Commonwealth. The impacts ofthis life-safety issue can be minimized if Storm Shelters (purpose builtstructures designed and constructed to provide life-safety protection from hurricanes)are required to be constructed in some types of new public buildings. Thisincludes provide a safe are for first responders and other government employeeswho are required to remain in harm’s way to manage and operational response tothese events.
COST IMPACT::
This proposal will increase the
cost of construction. Some of the most recent information on costs in available
in FEMA P-361, Safe Rooms for Tornadoes and Hurricanes. Guidance for Community
and Residential Safe Rooms (Third Edition, March 2015). Cost values described
herein come from this publication and previous editions of the publication.
FEMA’s safe room guidelines meet or exceed the design and construction
requirements of the ICC 500. Therefore, storm shelters should be able to be
constructed to the same cost criteria but there is no specific data available
at this time to quantify or confirm this statement. The FEMA publication (2008
Edition) stated “For large new building projects, however, the percent increase
in the overall project cost is quite small. For example, many safe rooms
protecting 200 to 300 occupants being constructed as part of a new school have
added only 1 to 2 percent to the total project cost when the safe room was
included in the design process at the beginning of the project.”
Further, based on 36 safe room
applications submitted to FEMA in 2008 the cost per square foot of the safe
rooms (in the continental U.S.) was less than $190 per square foot. Per Chapter
A3 of FEMA P-361, the average cost to harden new buildings to provide for a safe
room in a hurricane-prone region is between 5% and 8%. It is important to note
that the basic materials required for the construction of storm shelters are
the same as those for typical construction (reinforced concrete, reinforced
masonry, etc.). Special materials or assemblies are only required for door
assemblies and opening protection systems. Costs for storm shelters are
anticipated to decrease as their use becomes more widespread as these
construction materials are commonly used in the Commonwealth. The adoption of
requirements for storm shelters in hurricane prone areas for Group E
Occupancies and first responder facilities in the 2015 IBC will lead to
installation of many more storm shelters than are currently being built.
Subsequently, shelters will become less of a specialty item from a design and
construction standpoint. As the market expands for specialty products needed in
shelters, like hurricane resistant doors, windows and shutters, economies of
scale and new manufacturers joining the industry will also lead to cost
reductions.
