I'm the CEO for XIV services. Τoday I will speak about Building Information Modeling. I will present some aspects of how this hot topic, nowadays, is been presented around the world. So once again, thank you Marios and Parametricos for having us here. We're focusing on BIM Leveling today.
Yeah, Parametricos is reaching Level 3. I will explain later about the levels. Today we are going to speak for some case studies that we have.
The first one is from a Listed Building and the second one is from a World Monument. Our company was established in 2014 we are mainly BIM consultants and we provide design performance modeling analysis, on the process, some certificates that we have. This is the official name in Greek of BIM, Building Information Modeling for those who want to know.
The meaning of BIM is separated in three sections. It's the model, the thing that is produced, the modelling, how it's produced and the management. Who, what and when? BIM is not just a 3D model. It's all those things and more and it's actually a methodology. A Way of managing the information from the built assets. It's very important to understand this. Using different applications, different methods and connect them.
Building Information Modeling is separated in some dimensions. Most of you especially Architects, Engineers know about the 3D. We have another four. The question is why BIM and why now? so yeah, have to see that. It's very important and that's why we are discussing about BIM business. The global adoption, and the global goals and policies nowadays is based on these three topics, Climate, Social and Economic.
The reason is that we have a global movement on the real estate rising. Cities are growing, fast, and the economic power is shifting.
Some of our cities are getting aged and others have a younger population. The resources are changing, that's very logical.
So we have the new discussion for new businesses, on new technologies real estate assets and Big Data. Parametricos, is one of those and of course BIM is part of this evolution. But when did BIM start actually?
It's a good question. BIM is not something new, it's something very old. It's something from the beginning.
We're speaking about the process, that is actually something important to understand. We manage the capital expenses and make it easy to handle on the operational expenditure of a built asset. It's very important to understand this. This is the process of a built asset by starting the first initial programming meeting with a client and delivery to the whole life cycle.
This is the meaning of using the BIM process. The blue line from the traditional way of doing the studies on the AEC field and when we can see the benefits from BIM, is by eliminating those mistakes. Some of you have already seen a lot of them, around the world.
The question is how we measure, the BIM implementation, as a company as a country, as a community. To evaluate this, most of the countries agreed on some maturity levels. Those levels are explained in nowadays in four levels. It's a level 0 up to level 3. As you can see it's paper-based process and we're going to create a web service.
That's why I was saying before, that Parametricos is reaching level 3. The list on the left side are countries that already implemented the process and trying to make the best and the future discussions are focusing on what are the next levels 3, 4, 5, etc. This is a good graphic. so you can understand what are the discussions for the future.
Europe, released in 2017 this document, that they're expecting that by 2025 they are going to have those benefits and those numbers but it's very optimistic from my side. This is a statement from a construction company in US. You see the numbers, by implementing building information modeling and the numbers are coming from those numbers.
Why are we measuring the financial aspects? Because the process of BIM is based on controlling and managing the information of the asset. In Cyprus, we have done those steps in 2017, Cyprus BIM Task Group was established. The very first steps. We built the main framework. We launched our website, but it's empty for now.
Last but not least Cyprus is one of the biggest countries, in the leading countries in digital transformation of Cultural Heritage BIM.
I will show you an example of that in the case studies. In order to achieve BIM implemented on the process. Those are the three main pillars and there are six steps.
Start from the ground floor. Assembly your team. Prepare your equipment. Use a pilot project. Document everything. I mean everything and use consultants and experts in order to achieve the best values. Remember BIM is for everything. I will enter the case studies as I told you before, the first one is from a listed building here in Cyprus that we have already implemented BIM Level 1 and the second one is a Heritage BIM process on a war Monument, again here in Cyprus.
The first project is still on process, is not developed. But as you can see, it's a small project that is almost 200 square meters. We have already prepared 94 A1 paper sheets from the drawings and more than 40 reviews and renders. The equipment that I have used, and the softwares.
I have a video so I will try that video play. Exactly, what we have done here is that we used drones to fly around the property, photograph the property, and use that information from the images to prepare the 3D model. It took us only one hour on site and one hour in the office to prepare the model.
This is again another one video, but I think it's going to play. It's the processing of creating a Point Cloud Model that we use as a reference in order to create the as-built model. And those are the first drawings. I will repeat, we didn't measure anything on site. We just took photographs.
The quality we were able to make, all the small points that we have interest. This is the 3D view, of the existing site, some drawings, sections, details, again 3D model, as you can see the detail of the doors, we created also the structural analysis model with all the components of the building.
We created solar analysis. We were able to make the quantities from that model and this other one video is actually an automated process, just one click and you have all the elements calculated from the model.
All the building elements that were designed for the new model have all the information inside the structural information. So it can be measured. Those are the details.
Let's enter to the second case study. I don't know if you know the Church of Asinou, its a UNESCO heritage monument.
With the same process. We captured the reality by using drones. This is the result from photogrammetry, by using the images you can see the texture, how important is having that information. the interior frescoes of the church. We have already captured that. And that's the quality of the frescoes. We were able to see even the thickness and the different shapes on the surface.
This is the BIM model from the church. Ready to be used and reused. This is the 3D view environment from our PC. You can see the 3D model inside the point cloud model with all the frescoes and the exterior information. So for the first time, we have an accuracy on the 3D model. We have floor plans, so in case of a disaster the monument can be built again as it was, it's very important.
3D views, to understand the process. It's 3D sections. We actually took each element of the church and we add parameters inside, by adding parameters on the model, you're able to have more information, and more information is better quality for examination and we took that church in even more steps.
Remember that all these processes, we are speaking for only one model. We don't use different models only one model. So we took the HBIM model and make a test on the AR/VR engines available, HTML on the Web, different conventions from 3D game engines and controlling the data, we tested 60 commercial platforms available on that phase.
HTML conversion, and yeah, once again, sorry for not playing, but on that video, it's very important to see, we had used the church, by scanning the priest and using the Microsoft hololenses and controlling the church and the priest actually speaking to us, as we were visiting the church, without having a priest we were able to be there and listen to the story.
Hopefully, I will try to find the videos it's important to see it. So thank you for the presentation.
So thank you Simos again, we do, I personally have a couple of questions, but we can give to anyone that has to ask them now if anyone is interested, so Ferdinand,
The pictures of the church were amazing. Up to that point, no manual work has been done or how much work has been done when you created that model of the church that you showed the inside? Yeah, apart from the automatic digitisation.
We just used photogrammetry, by capturing images and 3D laser scan process with a Z+F company, a German company that provided their system. So we took the data from capturing the material and that's it.
Just capture the reality.
