The details I have seen involve the regular long concrete wedge anchors installed between the hollow cores, in the solid part. I would start by asking the structural engineer and/or hollow core manufacturer how they recommend installing seismic bracing attachments for the sprinkler piping. Welding attachments to the D-Beams may be an option as well (designed by a structural engineer). The regular short drop ins are not an option.
