be used depend on the subsurface characteristics at the site, which should have been
determined during the initial site investigation. A mismatch between the anchor type
and soil conditions could cause the anchor to fail and the tower to collapse. Note that
the load-carrying capacity of the soil can vary with the weather. For example, soil that
is saturated with water after a winter thaw may have much less load-carrying capacity
than the same soil at other times of year.
If anchors cannot be driven into the soil (e.g., because of underground facilities
or hazards), then concrete blocks can be used as counterweights. The two main
