Hello everyone. By this time I want to thank you all for taking our specialization in construction management by Columbia University. I highly believe, very also confident that we developed for you a series of four courses, or a set of four courses, or series of courses, that will give you a good intro level as I think most of you now noticed of what is construction management. This will help not only general contractors, not only construction managers and engineering firms, not only designers, architects, even owners and owner reps, as well as subcontractors. For all the supply chain that we can think of in the AEC industry. The architecture, engineering and construction industry. So this is specialization. Aimed and targeted for this audience. What we did in this specialization, we highlight these four courses. The four courses, it is highly, highly recommended to follow the structure that we developed and proposed for you. To start from course number one, two, three and wrap up with course number four because it's building on each other. But if you decided to jump into taking Construction Finance and then coming to Scheduling and then Cost management and control, and then Construction Project Management is still fine. But I would not recommend it. So it is up to you, but my recommendation from someone who worked for a good number of hours putting these materials with around plus minus or more than twenty people professionals highly experienced from the industry this is what we came up as a recommendation for you. Fair scores, what we highlighted, is before we start the project, the planning phase of the project, what you need to think about. From as I said, planning work redone structure, safety, sustainability. Risk, project delivery and so on. It's something or a class that will help you get kick start for entering and understanding what CM is all about. Second, after your understand the planning phase, it comes the scheduling phase. Before you even start the construction phase. So you want to build your schedule. That's the intent for course number two, to teach you all the ways the principles, the basics, the most common ways to build a schedule, to read the schedule, to interpret the schedule, of a construction project. Third, we look at construction cost estimating and cost control. Sometimes we refer to it as cost management. We also invited speakers, top well knowledged in the industry to deliver with us this material. Because, especially when it comes to cost estimation, you need experience. And I was lucky and we were lucky as entire team to have experienced people to come together put a lot of hours of work hours and efforts to build such class as well. Last but not least, the construction finance. Construction finance is a very important topic that you as an engineer, as an architect, as an honor rep as even a subcontractor or anyone of those or related to a construction project need to understand it. From the basics where we've covered, and the vertical finance of the real estate finance, and the the infrastructure of finance with introduction more a PPP, public private partnership. With all these courses we highlighted special topics, goes from lean construction to technology implementation from building information modelling, risk analysis techniques, program management. What's the difference between CM construction management, PM project management, PM program management? And we highlighted also another topics related to our project delivery and safety and so on. So, with that, this is a wrap up for our specialization. I really hope, that everyone of you, learned something from our specialization, that you can take to your project to the field and implement in the right possible way. Thank you for taking our specialization and looking forward to meet you here at Columbia or somewhere in construction conference or project overseas. Thank you.
