Each installation has a BOS contract, Base Operations Support, under the Public Works Officer. They have folks from all the trades that do facilities maintenance, landscaping, etc, among other things. Water main breaks? BOS has folks and equipment that dig up the road, fix the pipe, then repave the road. Leaky roof in your office, or hangar? BOS is the org that fixes it. Anything short of MILCON, if it’s repair or improvement, that’s BOS’ lane. Prior to PPV, BOS would have fixed your leaky faucet in base housing. typically, between BOS and PWD, they have a list of 1000 things to work on, and a workforce to actually do about 50% of that workload. While they’re very responsive to emergent tasks, like fixing that broken water main, they may not get around to fixing your leaky faucet, or replacing your dying AC unit in a timely manner. In contrast, the PPV maintenance team has a dedicated maint staff just for PPV, and can call in outside help if needed. While they aren’t perfect, my experience with PPV maintenance is that its is very good. They’re also under a ton of scrutiny and there are financial incentives attached to them having good maintenance metrics.
