That’s basically what it means however it pretty much only applies to site costs. So if they go to do your piering for example but it’s discovered that what was engineered originally, after your soil tests won’t be sufficient then they’ll add more and you’ll be sent a variation to pay. They can’t change the price for no reason. It’s only if something unforeseen comes up. That’s why we have an allowance for rock included. This is unforeseen as they won’t know exactly what we’re working with until they start digging. It was better for us to include the allowance then be out of pocket for however much it may cost.
