I think absolutely, that's why we put together that whole process and we invested in our tools and systems, we invested in our supply chain, fabrication, the construction capability of the company, so we've got that one-stop shopping approach that our customers are looking for; and in the same vein be able to kind of protect our way of executing an earning on those projects. So I think we're going to start to see -- break it down a little bit here, I think we already have pinch points in construction, we've seen in some of these projects that the industry -- not just Fluor but the industries had issues with -- it's almost exclusively because of either lack of talent or lack of people in that construction rank. What we've done globally is look at training and make sure that when those people aren't available to us in a location, we're setting up training programs to make sure we've got the welders, and the pipe fitters, and the electricians, and alike; so I think we're a little bit ahead of the game on that. I know we're marching backwards but I think construction is going to be the first place we see the pinch point because we've already seen it. Couple of years ago what we thought we were going to see before oil prices drop, I was really worried because we had to go to somewhere around 50,000 craft in the U.S. with the work we had but the projection said we needed to double that; I think that would have been an impossible undertaking given the situation at that time. Now again, since then we've spent a lot of time and effort on training people, so I think we feel good about being able to get those folks. On procurement, I think you'll start to see the pinch point in several ways but it's probably not until we get into late 2018 or early 2019. And you're going to see it in two ways; one is, there is going to be a saturation point given the capacities that are out there. And that's the first thing we'll see, it's going to be not how much does it cost but when can I get it which we've seen in the last cycles. Second piece is, is when they become stretched qualities challenge, so we're going to have to make sure that we're in those shops managing that work, and in some cases in this current cycle right now we've got fabrication yards that are providing for us, not the ones we own but we've actually had to go in and take over the management of those yards to make sure we can get the deliveries that we have to have. So quality is going to be the second thing that I think wanes [ph] but we won't see that until late 2019. Again, I go back to what I've said, if FIDs and pulling the trigger happens in the first quarter that would be the timeframe that we would see. On engineering, for us I don't see that it as a big challenge, and that's for two reasons. I still think that we're an employer of choice and the folks that have the big projects, that's where those people want to go to come and work and we've proven time and again that drawing those folks at our locations from an engineering and project management perspective have not been a challenge. Second piece of that is, in that integrated solutions model is the investment tools and systems that we've made and the dispersed execution so that we don't have to take Houston over 4,000 people again. We can leave it around 2,800 and the other offices where they are and moderately increase each of them that are supposed to having those booming bust this industry has typically had in those engineering offices. So, again, we had improved it, the projects in Kuwait [ph], I can tell you're proving that the process but until we get these awards going, we're not going to know whether any of those predictions on engineering, procurement or construction come true.
