You get what you pay for. I am sure this local thought because they had a guy on the building committee with home building experience they had it covered. Towns get into this kind of trouble all the time. The reason, not understanding what it takes to deliver project of this size. It goes like this...
1. We want a stadium, how much?
2. Well, that varies greatly on a number of factors but generally run $x per seat, so call it $60M.
3. Town bonds $60M
4. Town sets up an advisory committee of football parents, the coach, the AD, and an assortment of boosters and politicians. Basically, anyone who gets worked up over ceremonial groundbreaking ceremonies.
5. Said committee, starts asking for the moon, goes through several iterations and settles for asking for the moon and the stars.
6. Hired professional, eager to please, delivers exactly what they ask for and surprise, it's way over budget.
7. Committee grumbles about incompetent professional, demands a $60M stadium but can't agree to remove any of the shiny baubles they've spent the last several months bragging about.
8. Professional, still eager to please, more eager to stifle the moaning bastards, guts anything and everything that doesn't contribute to the wow factor. Budget back to $60M
9. Stadium is put out to bid and surprise, it comes in a tad over $60M.
10. Committee dips into construction management budget to cover overages and contingencies, hires local retiree to oversee the construction committee.
11. Committee assumes the contractor will do exactly what they bid and since they're professionals, everything will be jake.
12. As the budget is stretching, why are we spending so much on testing, I can tell good concrete from bad.
13. Yeah, we have a problem here.
