I can't quite figure out how they would be able to do 12 tons of payload to the surface of the moon using Falcon Heavy and NTO/MMH or kerolox (using a specific impulse of 310). It seems plausible if using hydrolox with a specific impulse of 450, though.
Rough calculations:
A 60 ton lander in LEO could go to the moon with 44.5 tons of hydrogen/oxygen, 12 tons of payload and 3.5 ton dry mass.
A 60 ton lander in LEO could go to the moon with 51.5 tons of kerosene/oxygen, 6 tons of payload and 2.5 ton dry mass.
Also, this is obviously assuming Falcon Heavy in expendable configuration.
