Golems extra hit points?

[dingle]

Could some one tell me how Golems get there bonus hit points from?
I reckon it's from there size but I can't find any reference to this in the core books. There con is stated as zero but they get a bonus +10, +20, +30hps, e.g. iron golem has 14D10 + 30 (with a zero con??). I've made a monster generator D&D 3.5 « Dingles Games but Golems don't fit any rules I know of so their hit points are wrong. I'd like to get it working correctly.

Are you looking for the bonus HPs that constructs get, ie SRD at:

Yep that's it thanks a lot. I thought it would be size related.

Golems are now working correctly on the monster generator
