Calculating premium
for Real Property has many different factors. One of the largest factors
involved is the type of construction of the building. Use this article to find
out how to determine what type of construction your building is, and what the
construction type might mean for your rates.
While there are various styles of buildings and many
different building materials available, each structure can be categorized into
a certain class, based on the construction of its outer walls and what the
floors consist of. Below you will find the different classes used, and how they compare to one another. The list is organized from Most Susceptible
to Fire, to Least Susceptible to Fire:
Frame/Brick Veneer:
This type of construction is the most common for homes and
small commercial buildings. This class gets its name from having the structure framed
and supported by wood or light steel frame. Brick Veneer is part of this
category because the brick on these buildings does not actually support the
structure. Frame construction is the easiest class to burn down or blow over,
but it is also one of the cheapest and most versatile buildings to construct.
Joisted Masonry:
In this class, the building is supported by cinder blocks,
precast cement walls, or layered, load-bearing bricks. When cinderblocks are
used, a brick veneer façade is often added for visual appeal, but, again, the
bricks add no structural support. While the outer walls are masonry, the floors
will be wood or light steel joists. Being so, this class is more expensive to
build, but is less likely to be burned down or blown over than Frame.
Non-Combustible:
As the name implies, these structures are made of
non-combustible materials. This type of construction is typical used for
utility buildings and garages, as the structure is entirely made of light steel
or similar light, non-combustible materials. These types of structures are
harder to burn down than both Joisted Masonry and Frame, but wind resistance
varies. These buildings are also less furnished than other structures (no
drywall, no insulation, exposed wiring, etc.), making them cheaper to build
than the other construction types.
Masonry
Non-Combustible:
In Masonry Non-Combustible, the outer walls are made of
cinder block, load-bearing brick, or poured cement, while the floors are either
heavy steel, poured concrete, or both. This is typically the type of
construction used for small to medium sized commercial/industrial buildings.
This construction type makes the building harder to catch on fire and sturdier
than the Joisted Masonry construction, making it safer.
Modified Fire
Resistive/Fire Resistive:
These types of constructions are used for mid-sized to large
buildings (E.g. Skyscrapers, multi-floor shopping complexes, etc.) as these
buildings typically hold a lot of people and a lot of property. The
construction can vary slightly, but these buildings are a step above Masonry
non-combustible as fire-proofing techniques have been used on the structure.
The jump from Modified to full Fire Resistive depends on the degree of the
fire-proofing done. The common fire-proofing test is a multi-factor test. (The
class rating is determined by the inside temperature staying below ‘X’ degrees
for ‘Y’ or more hours with a fire burning at ‘Z’ degrees. Different variants of
‘X’, ‘Y’, and ‘Z’ create different fire-proofing classes of fire-proofing. )
Why Do These Classes
Matter?
Determining the construction of the building is an essential
part to receiving a quote. All property-insurers will need to know the
construction type before they can provide a quote. This is because each
construction type carries a different rate, depending on its susceptibility to
certain perils (E.g. Fire). For example, let’s say you have an apartment
building you wanted to insure. You think it is Frame construction when it’s
actually Joisted Masonry. The premium you’ll pay is going to be higher than if
it was properly rated as a Joisted Masonry building. Furthermore, some
buildings are too risky to insure if they weren’t constructed with appropriate
materials. As an example, some companies will refuse to quote buildings over
two stories if they are Frame construction.
