That I’m not sure TBH. Second part is easy. They put out RFP’s and went at it. Lotta local guys got the contracts too which is nice so the revenue goes stays local. I lucked out as my company had the contracts with those local companies to maintain their equipment so when stuff broke, the entire County was breathing down our necks lol. I actually sent out a truck just dedicated to those companies and their fleets. It would literally follow the trenchers from site to site and be ready to fix it if it broke and we even did the maintenance in the off hours so the machines weren’t down for that. That’s a unique service our company offers. But I digress. The system would be finished if not for supply chain issues and getting nodes. I know a lot of it was funded via bonds but they got a good chunk of COVID cash for it. When the deployment first started it was tough but once the companies got synched up holy shit the speed of install was nuts. I got the fiber pulled, handholds and nodes installed, the pull to my house and the NID installed in under two weeks. The key is to not half ass it. The County spent a good amount of time engineering the system the right way. While everyone was screaming hurry up, they took the design and engineering time to make sure it was future proof and reliable. They really did a fantastic job and it was worth the effort. They do all the installs and customer service too and because it’s a County entity, they can’t fuck around without finding out from the people.
