Two 100 x 65 pre-cast concrete lintels for each opening.

Thanks.... 1200 x 100 x 65 should be fine then. The openings are only small enough for a 110mm pipe.... Or you recommend a shorter length?

Beams 400 long will do, as long as there is a 100 bearing each side. In fact, if the holes are only 110+mm wide, a full block will bridge it without the need for lintels.
