  Hadron ther­apy cen­tres are evolv­ing to­wards re­duced-foot­print lay­outs, often fea­tur­ing a sin­gle treat­ment room. The eval­u­a­tion of beam prop­er­ties, ra­di­a­tion pro­tec­tion quan­ti­ties, and con­crete shield­ing ac­ti­va­tion via nu­mer­i­cal sim­u­la­tions poses new chal­lenges that can be tack­led using the nu­mer­i­cal beam trans­port and Monte-Carlo code Beam De­liv­ery Sim­u­la­tion (BDSIM), al­low­ing a seam­less sim­u­la­tion of the dy­nam­ics as a whole. Spe­cific de­vel­op­ments have been car­ried out in BDSIM to ad­vance its ef­fi­ciency to­ward such ap­pli­ca­tions, and a de­tailed 4D Monte-Carlo scor­ing mech­a­nism has been im­ple­mented. It pro­duces tal­lies such as the spa­tial-en­ergy dif­fer­en­tial flu­ence in ar­bi­trary scor­ing meshes. The fea­ture makes use of the generic boost::his­togram li­brary and al­lows an event-by-event se­ri­al­i­sa­tion and stor­age in the ROOT data for­mat. The pyg4om­e­try li­brary is ex­tended to im­prove the vi­su­al­i­sa­tion of crit­i­cal fea­tures such as the com­plex geome­tries of BDSIM mod­els, the beam tracks, and the scored quan­ti­ties. Data are con­verted from Geant4 and ROOT to a 3D vi­su­al­i­sa­tion using the VTK frame­work. These fea­tures are ap­plied to a com­plete IBA Pro­teus One model.
