git grep -e span[0-9]
app/views/batches/edit.html.erb:        <td class="span2" />
app/views/batches/edit.html.erb:        <td class="span4" />
app/views/batches/edit.html.erb:        <td class="span3" />
app/views/batches/index.html.erb:<div class="span12">
app/views/batches/show.html.erb:<div class="span12">

This only applies to MIRA - T-DIL is new and cannot be compared to anything in Bootstrap2.
