Road projects fall through an average of two times
Do you have a source for this? I work in consulting and have never had a construction project fall through. Part of the mandatory bidding process is the contractor securing a bond against the value of the work, so that if they walk away, the Municipality can claim against the cost of the bond to complete the works.
Interesting. There must be some serious differences between there and here (Canada). I have no doubt companies fail here too, but even for companies that have soon gone out of business, they always finish their jobs.
We often only hire companies who can show past experience on similar sized projects, our bonds cover the full contract amount (every municipality around here has that requirement), and the contracts are generally pretty stringent on things like working days with severe liquidated damages for projects that go over the deadline (I’ve seen $500/day up to $3,000/day).
