Yes. So Andy, I guess, to start with margins, right, I mean, it's not -- the challenge with the business is margins aren't constant, right? So we're not going to -- even though we say 7% for the year, it is seasonal, right? First quarter is going to be lower because there's a number -- they do a lot of work in the north that's impacted by weather. So margins will be lower in Q1, they'll pick up in Q2, they'll be strongest in Q3, they should be strong in Q4. And the blend of that, we think, will be 7%, right, for the year or close to it. And we're -- we've worked it up on a project-by-project basis to get there. Our view on wind is wind will be down in '22 versus '21. It was down in '21 versus '20. Solar is going to be way up for us. And the reality is, like I said earlier, right, we've taken very conservative views on the revenue attainability. So if things went our way, revenues are going to be substantially higher in this business than what we forecasted. '23 should be an incredible year relative to bookings and what we're seeing from customers. And long term, our view hasn't changed, right? We think this -- we don't think 7% is the right margin profile for the business. We're growing at a considerable rates. And that growth is coming at a costs. We're doing it predominantly organically, which is expensive. But we think when we look at the outer years, it's going to be a business that's going to approach double-digit margins with very, very strong revenue. So I think the earnings potential in the business over the next 2 years is fantastic. And I think the problem projects that probably depressed margins through '21 that we've talked about, for all intents and purposes, they're behind us, right? We might have a little bit of bleed into Q1 and we had some in Q4. But outside of that, those projects will be done. Quite frankly, the project mix right now is really good. We're performing at really high levels across our full book of business and we're pretty excited about that. And if we can continue on that, again I think the second half of the year going into '23 is going to be fantastic.
