So those are the categories, and then within each category you've got credits. And here's a credit here, QL1.1 Improve community quality of life. So for that credit, there's a description for improved enhanced, and there's actually a writeup. And it'll tell you what that project needs to do in order to achieve an enhanced level or superior or conserving level for improving the community quality of life. And these levels of achievement essentially line up with whether or not the project is addressing any negative impacts, whether there are no negative impacts, or whether they are creating positive impacts. So improved, enhanced, and superior would be a project that is slowly, steadily mitigating any negative impacts. A conserving level of achievement is there are no negative impacts, and then a restorative is actually, you've gone above and beyond, and not only do you not have negative impacts, you've improved the quality of life in that community because of the asset. Again, I showed you a little bit of this on the website, but there's a guidance manual. There's a pre assessment checklist, there's the score sheet, oops, sorry. There's the verification and award program, so if you do have a project, that's highly sustainable and scores well. On the envision rating system, you can proceed with verification. And in order to do that, you would go through all the credits that you selected. You would provide back up documentation at that proved why you scored the project to the level of achievement that you did. And then you would submit that to ISI, and they would give that to a third party verifier. That third party verifier literally goes through each credit. Looks at what you scored the project, which level achievement you gave for each credit and it looks at the back up. And either they agree with you or they reduce it, or they in some cases, will actually give you a higher rating. And then you've given yourself. Once that's complete, you actually get the award. And then the last part is a professional credential, so if anyone is familiar with the lead process, lead you can take a lead exam and become a lead AP. For envision, you can take an envision exam, and you could become an envisioned SP, a sustainable professional. I happen to be both, and I think if you're willing to embark on a career in construction, this is such a growing facet of construction. It's a very valuable to have at least one, if not both, so that you have the ability to address any of these issues as they present themselves on a project. I mentioned earlier on the website that when you go through the checklist. If you want to then go further and score the project, this is how you would score it. So, this is the quality of life category. You'll see here that you've got in the purpose sub-category three credits. Credit 1.1, improve community quality of life. 1.2, stimulate sustainable growth and development. And 1.3, develop local skills and capabilities. Across, on the right hand side, you can either select NA, which means that that's not applicable. If it's not applicable, your point score is 0. And then you've got across the top there, you've got I, E, S, C, and R. And that's improved, enhanced, superic, and serving, and restorative. So you would simply select the level that you felt the project achieved. And then you would add any backup documentation. And in the guidance manual, it explains the level of achievement, what you need to do, and then it has an evaluation criteria, so gives you examples of the type of project documentation you need to. To produce to prove that you have achieved that level within the system. So, you would go line by line through all 60 credits. And come up with a score at the end. Once you've done running through all 60 credits, you can get a nice scoring summary like this. Up top, you have the applicable points, and I will give you a percentage of points that you've achieved. On the bottom is obviously a bar chart, so you can see where exactly you've done well. Maybe you've done well on resources, and natural world, but it looks like you can do some work where on the leadership category also, maybe you want to take a look at your team and how they're interacting with the stakeholders and implement some other processes or procedures to enhance the leadership capabilities of that project. These are the award levels. You've got bronze, silver, gold, and platinum. The percentages are associated with the number of points achieved, versus the number of applicable points. I often get the question why are these percentages so low, and the reason is envision assumes that the project is meeting all the legal requirements, and all the regulatory requirements. So, we have a pretty strict regulatory environment in this country. So our projects are typically held to a high standard in terms of the project, and its performance and how it impacts the communities. So what envision is trying to do is go beyond that percent achievement, envision means you went beyond the typical project. So if you reach 50% of the achievable points in envision, you get a platinum rating. Because you've gone that much further beyond where a typical project is expected to do. There's obviously a fee associated with it because they have to pay a third party verifier to go through your documentation and give you a score. Which takes, they have up to 90 days to do that, so on a billion dollar job, that could take a while. But you could look that, this is all up online, again, this is their link to their website, sustainableinfrastructure.org. And that's the end of the website tour. Here's another slide on the actual credits. So we talked a little bit about the different categories across the top and some of the subcategories, but this gives you an idea of what the 60 credits involve. Again, we discuss the levels of achievement. So lastly, I'd like to end by talking about where the industry's going. I did make the comment before that. If you look at where the most sustainable projects are, they're in states that are adopting alternative delivery method legislation, such as design build a P3. So, as the legislation spreads and owners become more comfortable with doing this type of project delivery mechanism. The number of projects is going to increase. So, sustainability in general, and sustainable rating systems to measure the sustainability of a project is just going to become more and more popular as the yeah, the industry grabs hold of P3s and design builds. On the owner side, they'll need to evolve to get more comfortable with this. And so we'll contractors and developers. And a lot of that is going to be as these projects get completed, there will be lessons learned throughout the industry. And I'm confident that a sustainable project is going to, again, bubble up as being one of those lessons learned in a key to a success on a large scale P3 or design build project. Social media and smartphones has created a huge opportunity to connect with the community. It's changed the way knowledge is being shared. Changed the way we've been able to communicate and get advanced notice on to people when we're doing things such as a traffic shift, or a new traffic pattern map. It's going to have an impact albeit at short term, but still an impact. Having websites and feeds of on all different accounts, really helps with getting the information out to the community. And just in general, you see it in the automotive industry, you see it in the food that you eat, the clothes that you wear. Sustainability and transparency is at the forefront of a lot of major industries, and people are realizing that it's the overall holistic approach that's going to make sure that we have a valuable product at the end of the day. And that these things last for a long time. And that we have a solid infrastructure to essentially build our economy on. With that, I'm going to end it here. And I want to thank you for your time. And I appreciate you listening to this lecture, and I hope that we've expanded your perception of what it means to be sustainable, and good luck.
