Using the lifting equipment, place
Modules in the sequence shown below in
Stage 3.C.
Adjust as necessary to make sure each
Module is level, in proper alignment and
at plan elevation.
Check plans and assure that modules
are oriented correctly with respect to
whether intake slots should be placed on
top or bottom.
As the modules are installed, shore the
system using temporary braces as shown.
These braces will no longer be necessary
after the structure has been backfilled,
but will help assure the modules stay in
their proper position during construction.
To assist in leveling the module, a heavy
plastic covered mallet may be useful
to seat the module and make minor
adjustments. Additional base material
may be added/removed underneath the
panel to address any low/high areas.
(Keep the panel attached to the lifting
equipment while adjustments are made,
and follow safety precautions).
Install and connect adjacent modules in
the sequence shown in the next section.
Align, level, and check elevations as you
go.
