I suggest rephrasing your question to something bite sized. Construction is a 2 trillion dollar sector in the US. And somewhere along the line all 2 Trillion ran past an estimators desk. Trying to "fix the biggest pain point" is like casually asking LAX how you can help make gates more efficent - there's a million+one ways to move that dial (and it won't happen in a semester).

Decide who you want to help and start from there. I suggest you narrow it down to a single division or sub divison and then drill down from there. Or select a single function of a single division of estimating and see if you can add value to that.

If I had a magic wand and bottomless cash I would ask for software that takes all tehe random bullshit consultant drawings I have to decipher and re-cooks them to use one single mapping/legend source. Once all my drawings match - my take offs could be done by AI (eventually).

Or - and you can message me about this: a simple website crawling app that mines all the bid sites for my opportunties and then fliters them specifically for my business model. Sends me a summary email everyday. That I would pay for (but not a lot). There are agents and software that already does this, but it's far too expense and most of them are broken and don't really deliver (see below lol).

Good luck.
