If you don't have a brilliant relationship with your neighbour then I'd be inclined to be more proactive. Ask for plans, ask about position of sewage/water/electric, ask for a written plan if damage etc. Get EVERYTHING written down. If they want access from your land, it needs to be in writing, and you can dictate the terms (and I would, tbh, as while your neighbour might be respectful I can guarantee the builders won't be).
Expect damage, even minor. Then, if there is you have a written plan (including a timescale within that for how long they can take to fix things). And if not - brilliant!
Btw, be realistic about the builders. They sub-contracted quite a bit on ours and, e.g., the brickies they used on the extension wall were so rude, disrespectful of neighbours, very loud radio, very loud swearing. I had to go round and tell them off pretty much every day, to the point where I would wait around the corner and then go back and tell them to STOP SWEARING again!! They were like little kids.
And finally: you can insist on a schedule but I've never actually known a builder work to one. This won't be your neighbours' fault, so be prepared to be assertive with the builders (and neighbour), insist on prior notice of any works that effect your house/land, even if their schedules shift, and be prepared to remind them of your terms when they go ahead.
A lot of the time your neighbour won't know what's going on - develop a relationship with the builders and remember that you don't have to be rude, but you don't have to be a pushover, either. The ones we have worked with over the years needed very clear boundaries. I was always polite but I was also very firm and very clear about what I wanted, when I wanted it, and what would happen if I wasn't happy. And if you need to repeat yourself, then do :) GOOD LUCK.
