To be honest, I don't know anyone in McIntire who is also majoring in engineering! I think the very intense workload at McIntire (you have to take a set amount of classes after entering McIntire) makes it impossible to pursue another major like engineering. Even the engineers here work 24/7, and have very little social life, as far as I can tell.
McIntire students who double major will typically pursue economics or mathematics, though the latter can be really tough with its course requirements. It is usually easier to double major within a school (ie. finance and accounting, or math and philosophy), however, though it's still possible to double major from two schools.
Btw, the new McIntire building, which just opened earlier this year, is very nice.
