Hi fellows, I hope that everyone healthy,

I have a doubt about to input cost compositions with auxiliary cost compositions in Spider, can someone help me? 

Look below, I have a cost composition for clear road side vegetation from estimate software that give $733.145,25 for 2.475.000m2, i.e. $0,30 / m2.

I tried to simulate the same composition in Spider using multi-resources because I thought that is better way, but unfortunately  the value is different, $0,33/m2, $820.281,89, I expected it to be exactly the same, but not.

What my mistake? the way is different? is there a viable way forward?

My inttention is to fit a model to control budget and delivery dates for main resources of the project like truck, bulldozers and so on.

Thank you in advance and best regards for all,
