The en­gi­neer­ing de­sign, in­clud­ing the spec­i­fi­ca­tions for the ac­cel­er­a­tor com­po­nents of the FAIR syn­chrotron SIS100 has been sum­ma­rized in the Tech­ni­cal De­sign Re­port. The final stage of tech­ni­cal plan­ning shall ap­proach pro­duc­tion readi­ness for the major tech­ni­cal sys­tems in 2010. Sig­nif­i­cant progress has been achieved in the de­sign of the cry­o­mag­net­ic sys­tem with its main dipole and quadrupole mod­ules, en­abling the pro­duc­tion of the first pre-se­ries dipole mag­net. Slight mod­i­fi­ca­tions of the lat­tice have been im­ple­ment­ed to equal­ize most of the cryo­stat in­ter­con­nec­tions, lead­ing to a sim­pli­fied de­sign and in­stal­la­tion ef­fort, and a re­duced va­ri­ety of com­po­nents and spar parts. The new par­al­lel tun­nel al­lows op­ti­mal short in­ter­con­nec­tions be­tween the sup­ply units and power con­vert­ers and the ac­cel­er­a­tor com­po­nents. The sta­tus of the en­gi­neer­ing de­sign of SIS100 will be re­port­ed.
