8% of construction projects from major companies ($5 billion+, publicly traded) are either on-time or on-budget. Obviously a smaller number are both. If you can really solve this problem, you can make a ton of money. Meanwhile, non-trivial projects with clauses like yours are less profitable and therefore tend to be the first delayed when resources are scarce. Which they frequently are. Unless you overpay by default. After all, "on budget" doesn't matter if the budget is 100x what other people are being quoted Meanwhile, how you described Boeing contracts doesn't seem plausible.
