If there is risk of physical damage to your home (due to blasting perhaps), the developer will send around people to document the current state of surrounding properties for insurance purposes. It sounds like this likely won't be an issue though. If they do damage your property, they would be liable for that. If you are concerned about it, make careful observations and take pictures before and after.
Otherwise, they are governed by the same by-laws you are. You can take a look at the noise by-law (

Edit to add: it might be worthwhile to have some perspective on this as well. Most of us on here aren't fans of this sort of development either, but if you just bought a new home in an adjacent development, trees were cut down and neighbours were inconvenienced for your home to get built as well. Buying into a new suburban development is part of the problem because it generates demand for more of it to be built (hence why you are going to have to put up with construction for the next little while). A little humility would be welcome.
