As say Geoffrey Mureithi - it's a syntax error -

$i = 0;
foreach($records as $r) {

$html .= '<tr>
    <td>'.escape($r->tecnologia).'</td>
    <td>'.escape($r->normaespecificacion).'</td>
    <td><img src="functions/'.escape($r->foto).'"></td>
    <td>'.escape($r->marca).'</td>
    <td>'.escape($r->modelo).'</td>  
    <td>'.escape($r->descripcion).'</td>
    <td>$'.escape($r->preciounitario).'</td>
    <td>$'.escape($r->iva).'</td>
    <td>$'.escape($r->instalacion).'</td>
    <td>$'.escape($r->totalcosto).'</td>
    <td>'.escape($r->garantia).'</td>
    <td><input type="text" value="0" class="imp"  size="2" /></td>
    </tr>';
    $i = $i+1;
}
