Firstly, I don't know where everyone is getting the Idea Earth is not going to be glassed. In the announcement trailer everything you can see of the Earth is being glassed, the General on the ground is begging the ships above to stop the apocalypse but they don't dare, none of their remaining craft have the power to do anything against the Assault carriers. The entire surface was black and burning.
Secondly, you guys are forgetting one key item that the UNSC has at their disposal... Flash Cloning. Just point an Engineer or two at a Cloning chamber and they'll perfect it for us, allowing us to Flash Clone as many Engineers as we could ever need.
Now, if I remember correctly Cortana could communicate with the Engineers. She did, after all, ask one to look at the Chief's armour and repair its shield system. Just how long, we'll have before the Covenant can put together their new fleet and send it to Earth we just don't know and as good as the engineers are, I don't think they do construction. I think grunt labor is just that, meant for Grunts.
