 Thanks very much and a warm welcome from me from our company as well So I'm going to tell you something about the reactivation of the historical Siemens one. Is anyone Arriving by S1 this morning Okay Did anyone arrive with the Siemens one? probably not because the Siemens one looks like this right now and That's going to change. So what am I going to show you here? I'm going to tell you something about the the project partners involved within this project Why we did use ArcGSTU BIM as a software for managing Stuff within the project What we did for construction planning? What we did for surveying and how we managed to model the Environment and some use cases with ArcGSTU BIM in a summary of course So we were in a project for a Deutsche Bahn Netze and they have made a project company Siemens Bahn engineer mineshaft and This consists of Krebs and Kiefer and Zweco and we were the surveying partner within this project Something about us we are situated in Berlin near the River Spree and Founded in 1992 we have office locations in Berlin Hanover and Eisenhüttenstadt about 120 employees and our headquarters is Situated right next there so we can take a swim in our breaks Okay, which reasons did we have for choosing ArcGSTU BIM in this project? There is a connection between CID BIM and GS data cloud-based in one system, which was really handy It was easy to work within the linked data in the project We could improve the collaboration between the project Planning the construction surveying architecture engineering all the departments that are involved within there and efficient decisions can be made of Of course time and cost savings are important as well Something about the project context the Siemens Bahn is a former line of the Berlin S-Bahn light rail It was established by Siemens and Halske about 100 years ago and the plan is to go live again Within the next four or five years There are a couple of stations that are completely out of service for quite a long time garden field Wernerberg and Siemensstadt the track is about four and a half kilometers long and was taken out of service for different reasons in 1980 so the route leads over historic railroad viaducts as you can see there and This is a plan of the Routes that will take place. It's a branch from the ring S-Bahn and going to the northwest and Direction of Spannau This is what it looks like right now. So as you can tell there needs to be reconstruction work done and New bridges or new construction of the existing structure needs to take place There are about 30 main engineering instructors that we have been taken care of in the surveying business and there needs to be infrastructure for rail traffic the stations need to be refurbished and They need to be connected to the main S-Bahn lines in Berlin And we have the three stations that are out of service for quite a long time And they need to be taken back into service and to be refurbished completely So there is quite a demanding Planning situation due to the historical monuments that we are faced with here looks like bits of If anyone's interested in lost places photography is a good place to go there looks brilliant and the project goals are the usage of the existing viaduct structure and we have to Provide a base for the recalculation. What needs to be done in steel construction masses design features and To provide the planning data for the refurbishing process and our precise model surface a base for that planning process right now we are on the stage of Preliminary planning and the commissioning is planned in 2029 Estimated cost about 500 million euros. Let's talk about that in a couple of years if we are still talking about 500 millions We will see I can't tell you my guess is Might go up a bit Okay, we did the surveying of the old Wernerberg station and the connected Elevated railway infrastructure and we created BIM models with a great detail level LOD 400 which is Very fine grained of the viaducts and that's outstanding Level of detail if you compare it with other in inventory projects that have taken place before that And we integrated all the gained data in 3d models and ArcGIS Geo BIM and connected it with Autodex construction cloud So that's a colleague of mine song, okay, and What we see here is a laser scanner mounted on a post and We did 48 double-track railroad viaducts of the elevated line that you can see on top here on the picture We scanned the whole station So the reception building roofing if it was still intact and the stairs and the surrounding terrain and We used a Tehematical Cadastra for the shaft cadastra so cable sewage service water and the guide systems oops So personal support was involved in the project as you can tell on the left. That's me I'm I took a chance to do a bit of serving as well And tight project budget so involvement of child labor my son Took part in the project as well and managed to do some BIM modeling stuff and that's what we gained from the Modeling process you can see here the detail level on the left side You can see the latest scanning data that we gained and on the right side There are the model components of the historical viaducts. So it's Yeah, very detailed. You can see every part of it and if it's modeled correctly, you know how many Steel is built in there and which parts are Within the construction Within ArcGIS Geo BIM we were able to integrate some other geodata in the project so the land use plan the digital terrain model 3d models of environments and buildings and We used GIS analysis tools for getting profile serving profile visibility analysis Shadowcasts weather and stuff like that. So things that you can't really do an arc in an Autodesk and you're able to do within the GIS environment and We could use the the platform within the cloud to Involve all the stakeholders in the project. So We use an editor and you could command some parts of the project you could Provide location descriptions you could do a photo documentation in the project site documentation and you could also do Classical BIM issue management So collision detection within the model if there is anything that might cause problems in the future that you can already see within the Model structure you can use a time slider for Getting to know where did the Problems occur within the project and on a time scale And you could edit the features in ArcGIS Geo BIM or in the Autodesk construction cloud Right. So for the summary of the project It was very efficient technology for surveying that we use there for the special infrastructure the Planning for the Survey site is crucial, especially within historical buildings like that We managed to capture the details very precise It was fast field work that could be done with a laser scanning faster than we first approximate it so it was rather cost effective and the gain model is modeled in according to the BIM methodology and We derive detailed building informations So the model that we created is sufficient for the works and the Constructions that are ahead of the project for the reactivation of this track and we could Get all the characteristic features from the data that we needed Yeah, so time and cost servings we integrated 2d and 3d in the cloud for all the participants We use the analysis tools. We used the issue management for collision detection editing We could add commands and documents on the project we could exchange with all the stakeholders in the project and The model can be viewed in all necessary contexts. So yeah, it was I think Very good project that we had so far. It was interesting to see how you can manage to capture this old structures with it and very new and modern technology and To close I have some pictures that we've taken on the old Stations that I think Yeah, quite interesting to see so wo bleibt denn der Zug it takes a bit of time Before the trains rolling there and these are some impressions from the station building of Wernerberg So as you can tell there's quite a lot of things to do that Need to take place on the track okay, so that's So far from me and if there are any questions, I would be able to answer them for you or Thanks for your attention
