Automated extraction of objects from remotely sensed data is an important topic of research in Computer Vision, Photogrammetry, Remote Sensing, and Geoinformation Science. In order to discuss recent developments and future trends in research in automatic object extraction and their influence on sensors and processing techniques, the two ISPRS conferences "Photogrammetric Image Analysis" (PIA) and the "Munich Remote Sensing Symposium" (MRSS) will be held as a common event for the first time. The aim of the common event is to seek, exploit and deepen the synergies between geometry and semantics, and to give the two scientific communities the possibility to discuss with and to learn from each other.

Ph.D. scholarship in BIM-GIS integration by LOC

The TUM Center of Digital Methods for the Built Environment (Leonhard Obermeyer Center, LOC) is offering a Ph.D. scholarship for research in the field of BIM-GIS integration with a total duration of three years.

In the frame of the announced Ph.D. scholarship, a deep integration of BIM and GIS data and technologies is supposed to be investigated. In this regards, the focus is on the design, construction, and operation of built infrastructure (roads and railways). In recent years, the model development in this field has been driven forward in both the GIS and BIM domain; however, mostly isolated from one another, resulting in divergences and rendering overarching analyses difficult to perform. Accordingly, the scholarship holder is expected to systematically analyze the semantic structure and granularity of the data models CityGML, InfraGML and IFC-Infra, to critically investigate the suitability of Linked-Data approaches and to develop and experiment new approaches of semantic alignment. The interaction with international research projects will form part of these endeavors.

Springer publishes book "Building Information Modeling - Technology Foundations and Industry Practice" edited by Borrmann et al.

24. September 2018

Building Information Modeling (BIM) refers to the consistent and continuous use of digital information throughout the entire lifecycle of a built facility, including its design, construction and operation. In order to exploit BIM methods to their full potential, a fundamental grasp of their key principles and applications is essential. Accordingly, this book combines discussions of theoretical foundations with reports from the industry on currently applied best practices.

The book’s content is divided into six parts: Part I discusses the technological basics of BIM and addresses computational methods for the geometric and semantic modeling of buildings, as well as methods for process modeling. Next, Part II covers the important aspect of the interoperability of BIM software products and describes in detail the standardized data format Industry Foundation Classes. It presents the different classification systems, discusses the data format CityGML for describing 3D city models and COBie for handing over data to clients, and also provides an overview of BIM programming tools and interfaces. Part III is dedicated to the philosophy, organization and technical implementation of BIM-based collaboration, and discusses the impact on legal issues including construction contracts. In turn, Part IV covers a wide range of BIM use cases in the different lifecycle phases of a built facility, including the use of BIM for design coordination, structural analysis, energy analysis, code compliance checking, quantity take-off, prefabrication, progress monitoring and operation. In Part V, a number of design and construction companies report on the current state of BIM adoption in connection with actual BIM projects, and discuss the approach pursued for the shift toward BIM, including the hurdles taken. Lastly, Part VI summarizes the book’s content and provides an outlook on future developments. Powerful and sophisticated software products are now available that provide the technological basis for realizing BIM-based construction projects.

The book was written both for professionals using or programming such tools, and for students in Architecture and Construction Engineering programs.

18. July 2017

Beim Bau der Elbphilharmonie in Hamburg wurden mittels Computersoftware die Komponenten von Akustik und Ästhetik vereint. Über diese wachsende Verbindung von Architektur und Algorithmen wurden Prof. Frank Petzold und Dr. Christoph Langenhan vom Lehrstuhl für Architekturinformatik in der Wirtschaftswoche interviewt.

Am Lehrstuhl für Architekturinformatik an der TU München lernen die Studierenden neue Technologien und Systeme für die Architektur kennen. Als zentraler Forschungsgegenstand wird ganz allgemein der Computer als umfassendes Entwurfs- und Planungsmedium behandelt. Dabei versucht der Lehrstuhl, sich sowohl kritisch mit den neuen technologischen Vorgehensweisen auseinanderzusetzen, als auch die Methoden gewinnbringend für den Berufsstand einzusetzen. Eine solche Erweiterung verändert auch das Architektenbild.

Dementsprechend spricht Prof. Frank Petzold im Interview mit der Wirtschaftswoche auch davon, dass Architekten durch die neuen Technologien bis zur Grenze des Möglichen gehen, während Christoph Langenhan betont, inwiefern auch handwerkliche Arbeitsprozesse davon profitieren.

Der Artikel zeigt am Beispiel der Elbphilharmonie die neuen Entwicklungen: Das besondere Klangergebnis des neuen Konzerthauses konnte nur dank der Anwendung von Algorithmen im Entwurfsprozess realisiert werden. Benjamin Koren (Büro One to One) schrieb dazu extra ein Computerprogramm, das die Anforderungen des Architekturbüros Herzog & De Meuron sowie die des verantwortlichen Akustikers Yasuhisa Toyota erfüllte. Dieser Arbeitsprozess mit Algorithmen wird im Artikel detaillierter geschildert, um dann weitere Beispiele computergestützter Architekturen zu erläutern wie beispielsweise das Nationalstadion in Peking.

Der Artikel „Besser bauen mit schlauen Algorithmen“ erschien am 07.07.2017 in der Print- sowie am 16.07.2017 in der Online-Ausgabe der Wirtschaftswoche.

The Chair of Geoinformatics is one of the landmarks in the “Land of Ideas”

Thanks to the project “Smart District Data Infrastructure”, the Chair of Geoinformatics at the Leonhard Obermeyer Center is one of the winners of the competition “Landmarks in the Land of Ideas 2016” – in the science-category. “Smart” three-dimensional city models can help metropolises to simulate future developments and to develop solutions. In order to make life in the city worth living, the municipalities have to plan ahead – for instance concerning noise or fine dust pollution. The Smart District Data Infrastructure concept, which was developed by the geoinformatics-specialists of the Leonhard Obermeyer Center, provides planners with the tools they need. Cities or individual districts can be depicted as virtual 3D city models, which are linked to various sets of data. This way, future developments can be simulated, allowing to develop solutions at an early stage. The competition – a project by the initiative “Germany – Land of Ideas” and the Deutsche Bank – aims to promote forward-looking ideas focusing on the potential of togetherness in the sense of community, cooperation, and networking, thus creating social value in the way of solving current or future challenges. The high-ranking jury was of the opinion that – according to this year’s motto “NachbarschafftInnovation – Gemeinschaft als Erfolgsmodell” – the project provided convincing answers to the question of how joint activities can bring about innovative solutions to the challenges of tomorrow.

Newforma is a new member of the Leonhard Obermeyer Center

Due to the increase of digital information in construction planning and implementation, information management systems are becoming more and more important. Thus, we are especially pleased that our research network now has a new partner who can offer expertise in project information management. In this context, we would like to give our new member the opportunity to introduce the enterprise: “Newforma is the answer to the exponential growth of data in construction projects. Non-intrusive Project Information Management (PIM) serves as a basis to capitalize a company’s digital information intuitively and intelligently. Using Newforma PIM software solutions, it is possible to find solutions to operational questions regarding a project within fractions of a second – not by searching for files, but by searching for specific information and by understanding the interrelationships. Newforma provides a possibility to edit and redirect search results without changing the original file, and without having to create duplicates and, thus, redundancies. Newforma covers the entire lifecycle of relevant sets of information, including their formal and informal exchange. Thus, it is possible to audit and reconstruct every single step in which information was edited or passed on. LeanPlanner – Newforma’s project planning software for architects, planners, and contractors – is based on lean methods. Thus, it is possible to clearly visualize the workflow, to optimize processes, and to ensure efficient project-specific value chains. Newforma software solutions are already being used in more than two million projects all over the world. In Central Europe, Newforma has been present since 2015, with offices in Munich, Paris, and London.” Andres Damjanov, Newforma Germany

The award, which includes 2000 € in prize money, was presented to him in the scope of the opening session of the round table event in Munich on February 24, 2016. His thesis, which he developed at the Chair of Geoinformatics during the winter semester 2014/15, addresses the analysis of solar irradiation using large 3D city models in the CityGML scheme. Another aspect, in addition to the automated calculation of solar potentials, is the possibility of enhancing city models with analysis results. A copy of the thesis can be downloaded from the internet free of charge.

Successful launch of the BIMsite project

The research project BIMsite started off with a meeting at Technische Universität München. The framework of the project, which is funded by the Bavarian Research Foundation (“Bayerische Forschungsstiftung”), aims to explore new methods of BIM-supported construction process simulations for the optimization of construction processes, logistics, and construction site equipment. The Bavarian Research Foundation contributed 620,000 € to the project. In addition to numerous industry partners, the Institute for Materials Handling, Material Flow, Logistics and the Chair of Computational Modeling and Simulation at the Leonhard Obermeyer Center are involved in the project as well.

The BIMsite project focuses on the interface between construction planning and the construction work itself. Nowadays, it is still common to use printed 2D-documents at this point of information transfer. This tends to lead to a loss of digitally available information, as the construction process is planned using manual methods. The BIMsite project addresses the question how digital building models can be used in the preparation phase and throughout the construction work. On the one hand, it serves to examine which requirements building models must be able to meet in terms of information content and level of detail, to ensure that the data can be used for the corresponding project phases directly. In line with this, another focus will be on model-based methods of construction site simulation as a means to draw conclusions regarding the project’s critical objectives of productivity and safety. In order to validate the prognosis models, the idea is to rely on methods of construction site monitoring, which will also allow for dynamic adaptations and possible rescheduling during the construction process.

A new innovation and start-up center in Munich

Munich, the Bavarian capital, and the EntrepreneurTUM GmbH – which was founded by entrepreneur Susanne Klatten – are planning a new innovation and start-up center at the “Kreativquartier”. Here, start-ups, established companies, creative folks, and scientists – in a dialogue with city planners, architects, and the public – will be able to work on innovative products, intelligent technologies, and future-oriented services for the city. This approach is unique, and Munich will take a leading position in the development of “Smart City”-solutions thanks to the new innovation and start-up center. On February 16, 2016, the Economic Committee of Munich’s city council had announced that the project was to be implemented. The center will offer enough space as well as the necessary infrastructure for 40 teams to work on their ideas for a period of one year.

Munich is an excellent location for technology-startups: six DAX-listed companies, many well-established mid-sized businesses, a unique industrial diversity, an inspiring proximity to universities and research institutes, a strong investor scene, highly qualified workers, and Germany’s most profitable cultural and creative industry. In the future, the innovation and start-up center is supposed to become a home to this community, integrating the creative industry based in the “Kreativquartier”. Networking with the creative scene opens up new possibilities for interdisciplinary collaborations between start-ups and artists, designers, or architects – an important impetus regarding the subject matter “Smart City”. Another relevant aspect is the proximity to the world of science, an ideal location for the development of technologies in the fields of environment protection, energy efficiency, raw materials and material efficiency, data exchange and networking, energy supply, as well as urban mobility. In addition to the Technische Universität München as a key partner, other universities and research institutes from Germany and abroad are invited to contribute their expertise as well. Located in the city – on the premises of the former “Luitpoldkaserne” – the new building in the “Kreativquartier” will offer ideal conditions to work on solutions for urban environments and to include the public at an early stage. Munich’s municipal works (“Stadtwerke”) are planning to cooperate with the new center and have already signed an extensive letter of intent. Following this approach, and taking existing initiatives such as the European project “smarter together” into account, Munich could soon play a leading role, globally, in the field of smart city solutions. Bavaria’s Minister of Economic Affairs, Ilse Aigner, welcomes the commitment of UnternehmerTUM and the City of Munich, and the Bavarian Ministry of Economic Affairs will continue to support the project.

The construction of the new innovation and start-up center for “Smart City”-solutions – with about 10,000 sqm of office space as well as event rooms, co-working spaces, and a prototype workshop – is scheduled to begin in 2017. The city of Munich will provide leasehold property, and UnternehmerTUM will cover the costs for construction and operation of the new building. The next steps are to flesh out a detailed concept for the new building, to acquire further partners, and to find a general contractor with the involvement of the City Council. 

Virtual 3D Model of New York City in CityGML LOD1 available as Open Data

Our team at the Chair of Geoinformatics of Leonhard Obermeyer Center at the Technische Universität München has created and published a virtual 3D city model of New York City that can freely be download from our project homepage. Also an Open Source 3D web viewer is provided allowing immediate interactive exploration and querying of the 3D model.

The city model is purely based on Open Data from the official Open Data Portal of NYC. 26 different datasets were integrated. From the 2D and 2.5D geospatial data around four million objects with 3D geometries were generated by a fully automated process. The resulting dataset covers the whole area from NYC and contains 3D buildings with addresses, streets, land lots, water bodies, parks, trees, and a triangulated digital terrain model. Most objects carry semantic information, because different thematic datasets from NYC administration were joined with the 3D model and their information was integrated. For example, most buildings carry information about the owner, construction year, residential area, commercial area, office are (all in sqm) etc. The 3D model is provided as a CityGML dataset in Level of Detail 1 (LOD1). The total datasize is around 1.6 TB of XML data (around 80GB compressed). At this moment the building models (> 1 million), streets (150,000), and land parcels (> 860,000) only are ready for download (around 12 GB of XML data).

The data transformation and integration processes have been developed in the context of the two master theses of Mrs Barbara Burger and Mrs Berit Cantzler at TUM. The implementation is based on the Feature Manipulation Engine (FME) from Safe Software and our Open Source geodatabase 3DCityDB running on Oracle Spatial 12c. A paper summarizing the work and the results has just been presented at the Photogrammetric Week 2015 in Stuttgart, Germany. It can be downloaded together with the datasets from the project website (see below).

Using 3DCityDB, a tiled KML model was exported that can be interactively explored in our new Open Source 3D Webclient for 3DCityDB. The Webclient extends the Open Source software Cesium Virtual Globe by means to manage large tiled 3D models in KML, object highlighting etc. The viewer has been developed by Zhihang Yao and Kanishk Chaturvedi, both being PhD students at the Chair of Geoinformatics @ TUM.

Digital change is in full swing. Therefore, the Bavarian Government initiated the “Zentrum Digitisierung.Bayern”, and the kick-off event took place at Campus Garching (TUM). Manfred Broy, Professor of Computer Science at TUM, is the Founding President and Managing Director.

The Leonard Obermeyer Center was one of the hand-picked exhibitors at the opening event of the ZD.B, and LOC-researchers presented cutting-edge research in the area of ​​digital methods for planning and construction to Bavaria’s Minister of Economics, Ilse Aigner, to Minister of Science Dr. Ludwig Spaenle, and to the many other guests.

For example, a more accurate data base could help to estimate schedules, costs, and possible risks of building projects – and three-dimensional planning and representation of buildings could ensure more transparency and better accuracy in the planning phase. Also, interactive human-computer interfaces could provide direct feedback based on analysis and simulation. The researchers of the Leonhard Obermeyer Center were supported by representatives of CADFEM, who introduced the current research project DETORBA. The aim of the project is to improve the predictability of the effects of detonations in urban environments.

TUM is on its way to become a digital university, which means that digitization has an impact on research and teaching in all scientific disciplines. At the same time, the researchers are exploring important aspects of digital technology – from the fundamentals of computer science to practical applications. Digital construction is one of the key topics, which is why TUM aims to establish a close cooperation with the ZD.B.



Underground-visions: The “Süddeutsche Zeitung” on LOC-researchers

For a research group led by Prof. André Borrmann, the planning of the second S-Bahn line serves as a practical example regarding the development of new digital planning methods in the field of infrastructure projects. In connection with the current planning phase of the second S-Bahn line in Munich, the “Süddeutsche Zeitung” published an article on our current research activities in the scope of “BIM for Infrastructure”:

“...the aim: to date, changing some detail in a major project – such as, for example, altering a tunnel’s position in the ground because a pipeline is in the way – will also have other effects, making it necessary to readjust signals, to change rescue routes, and to redesign drainage. This is not only time-consuming, it also costs a lot of money. In the future, the TUM researchers hope that changes like this will be implemented within a ‘highly dynamic model’ by a few mouse clicks,” says Rank. Thus, the planning phase for the second S-Bahn line will lead to important results in any case – even if the second tunnel might not actually be built in the end.

Knauf: a new industrial partner for the Leonhard Obermeyer Center

It is a pleasure for us to be able to welcome Knauf as an important new industrial partner for the LOC. The company name Knauf, established 75 years ago, stands for outstanding quality and creative solutions – for craftsmen, consumers, and construction companies, as well as for architects and planners. Knauf products are made and distributed all over the world by more than 20,000 employees in over 150 factories and subsidiaries. The high-quality system products by Knauf Bauprodukte GmbH & Co. KG cover the entire product range of interior construction.(

As a manufacturer, Knauf is interested in integrating digital semantic models of its construction products into building information models in order to simplify their use in the planning phase and, thus, to make the products even more attractive. The practical challenge is to be seen in the individual and system-based character of the products.

Joint research projects will serve to investigate the potential of digital methods, leading to a prototype implementation. We are looking forward to our joint activities.



A huge media echo: the Leonhard Obermeyer Center at the convention of the CSU’s parliament faction

Following an invitation by the CSU, researchers of the Leonhard Obermeyer Center at Technische Universität München – led by Prof. Rank and Prof. Petzold – presented pioneering digital planning tools to the parliamentarians in the course of their meeting in Wildbad Kreuth. Interactive models served to visualize the new range of possibilities regarding infrastructure projects: improved citizen participation, potentials for the reduction of energy consumption in entire city quarters, potentials for (re)densification, and improved means to predict the risk of floods. Using an interactive table, combining haptic and digital models, the politicians were able to act as city planners and to optimize their cities, supported by real-world simulations. The politicians and the numerous media representatives were very interested, which shows how important the aspect of digitization is for a modern state. It will not only lead to a profound change in public administration, but digital models will also help to implement large-scale construction projects. Understanding, participation, and acceptance on the part of the citizens are key factors to the development of sustainable regional planning.



LOC-researchers win three prizes in the competition “Auf IT gebaut”

The first and the second prize in the category “Civil Engineering” of the competition “Auf IT gebaut” go to Simon Daum and Cornelius Preidel – for their projects “Anfragesprache QL4BIM” and “BIM-supported Code Compliance Checking”. Further, the first prize in the category “Architecture” goes to Dr. Gerhard Schubert for his project “Interaktionsformen für das digitale Entwerfen”.

The nationwide competition for researchers in the field of “Building IT” goes back to an initiative by the Federal Ministry of Economic Affairs and Energy (BMWi) and the social partners of the construction industry. It is organized in cooperation with the RKW Competence Center. The award ceremony took place on Tuesday, January 20, in the context of the “BAU 2015” trade fair.



BIM in the building industry – changing planning processes

DETAIL Congress: November 27, 2014, in Munich

The process of digitization is leading to significant changes in the field of building design and building construction, and Building Information Modeling is one of the key factors. But what is behind the BIM-based design and planning methods? How does BIM work in reality? And to what changes will the widespread use of BIM lead regarding your work processes at the office and at the construction site?

Date: November 27, 2014 (from 1:00 pm to 8:00 pm) Location: TUM, Enrollment Hall (“Immatrikluationshalle”) Arcisstraße 21, 80333 Munich

Background Building Information Modeling, “BIM” for short, has become a well-known term in the interdisciplinary field of building design and building construction. The introduction of BIM-based processes is in full swing, as politically intended, resulting in significant changes for anyone who is actively involved in the construction process – as many cost-relevant decisions can be implemented correctly at an early stage in the design phase. This means that architects and planners as well as companies have to address and become acquainted with the topic of BIM-based planning.

The conference will provide answers to the most urgent questions concerning BIM, with the help of technical lectures and expert reports by international architects who are already using BIM processes for their projects successfully.

After the lectures, there will be a get-together in which the participants and experts can get to know each other. Collaboration partners are the Leonhard Obermeyer Center at Technische Universität München, the Fraunhofer Institute for Building Physics IBP, and the Federal Association for Building Software (“Bundesverband Bausoftware e.V.”).
