Last, but not least Section
5, Community Colleges and
Other Topics. 
We're approaching the end of this 
presentation, there are a few items
that still haven't been addressed
and we'll just skim them quickly
at the end.
One is Segmented Wall Systems per
IR 16-3,Glass Unit Masonry IM 2.5, 
Masonry Retrofit and
Non-structural Layout Issues.
This is a picture of a layout of
a typical segmented masonry wall.
Another picture showing
closer up of a segmented wall.
You can see the netting behind
it for compaction in order to
properly brace the walls for
its retained earth requirements.
Not much has changed
for glass unit masonry.
They can only be used
for non-structural walls.
Maximum panel side is 25'
horizontal and 20' vertical maximum
based on wind load designs.
Standard thickness is 3-7/8"
thick, it must be supported
on all edges by either masonry,
concrete or steel, there must be 1"
confinement at the top of the edges,
all gaps must be filled at head 
and jamb areas, horizontal
reinforcements required at
16" on center max.,
joint reinforcement consists
of two parallel wires with wire cross tie.
Other masonry issues are retrofitting
nonreinforced brick walls.
And you see in this illustration where
they've used strongbacks to anchor
the masonry blocks to hold them in place.
Here's another typical picture of
strongback of unreinforced masonry walls.
Another good typical issue in
masonry construction is the
location of non-structural openings.
You can see in this illustration,
that there are a few openings at
the top of the wall the structural
engineer has not taken care of.
This may have been missed in the design
and construction and the plan review.
This does have to be brought to the
attention of the structural engineer
or DSA. 
Last but not least is issues
concerning community college  
which is unique to DSA and 
K-12 schools. 
There are alternative building standards
when it comes to community colleges. 
Community colleges may elect to use 
different code requirement design 
parameters and amendments in the 
CBC Chapter 21 for masonry units. 
The amended list and CBC 2101 
and 2114 identifies DSA-SS/CC
to locate and show the differences
in code. 
The DSA-SS amendments were carried over 
except those that do not contribute 
to the seismic and safety performance. 
The removed presciptive grout construction 
requirements and the following 
slides will highlight the difference 
between the DSA-SS and the 
DSA-SS/CC differences.
These are the code sections that
cover typical provisions in the
community college code requirements.
The four main issues and differences
between the community colleges and DSA is
the segregation of grout material
provisions are not adopted when
non-structural safety issues performed.
Partial grouting is allowed
in freestanding sidewalls
that use running bonds. DSA-SS
requirements for reinforcing grout
masonry is not adopted,
and you'll see that on the next screen,
and this includes requirements that
grouting procedures shall be described
on construction documents
since DSA-SS has high-lift and
low-lift grouting procedures.
The following are the general DSA-SS
requirements that are not adopted.
One is stacked bond requires
open-end units 16" center spacing [of reinforcement].
Second one is vertical cells
clean grout space dimensions,
you'll have to check Table 3.2.1
for requirements.
The clear space between masonry and
reinforcing is one bar diameter,
that's not included.
The minimum depth of a bond
beam channel is not restrictive.
And the requirements for high-lift
and low-lift construction is not
required for community colleges
for construction.
Another item that DSA requires
that the community college code
does not require is testing of the
compressive strength of the grout
when the f'm
is greater than 2000 PSI.
Now we're approaching the
completion of our presentation.
These are the typical items that
have been covered in this class.
So please be aware if you have
any questions, please direct
them to your DSA field offices.
This concludes the Masonry Section of the
Project Inspector Overview training class from DSA.
Thanks for attending.
