I would do this a little different. I’m only including enough to give you an example
<?php
if (have_rows('bp_client_logos')) {
// there are rows in the repeater
// create counter
$count = 0;
?>
<div class="section"><!-- open first .section -->
<div class="row"><!-- open first .row -->
<?php
while (have_rows('bp_client_logos')) {
the_row();
if (($count%16) == 0 && $count > 0) {
// we have output 16 repeater rows
// and this needs to be the first row of the next section
// close the last row and section opened
// and open a new section and row
?>
</div><!-- close last .row -->
</div><!-- close last .section -->
<div class="section"><!-- open next .section -->
<div class="row"><!-- open next .row -->
<?php
} // end if 16
?>
<div class="column">
and display the rest of the row content here
</div>
<?php
// increment count
$count++;
} // end while have_rows
?>
</div><!-- close last .row -->
</div><!-- close lase .section -->
<?php
} // end if have_rows
?>
