Internet of Construction

Information networks for cross-company collaboration in the production chains of construction industry

 IoC - Internet of Construction


  • In the construction industry, a large number of different companies work together to create highly individualized products
  • Time delays, construction defects and cost overruns often result from insufficient data exchange between companies
  • Digital building models (BIM) have the potential to improve the networking of companies along the value chain
  • The digital building models of the planning phase are currently insufficiently used for prefabrication or on-site construction
  • Increasing the adherence to schedules and construction quality by means of an integrated flow of information along the value chain
  • Track & Trace to enable the flow of information and logistics
  • Creation of a Reference Architectural Model for cross-company cooperation in construction
  • Extension of the BIM framework by information flows between building planning, modular prefabrication and on-site construction
  • Development and testing of exemplary applications for the use of data and data feedback in prefabrication and on-site construction
  • Definition of requirements and application scenarios in cooperation with industry partners
  • Development of a construction approach by analyzing the information flows
  • Development of adaptive production units, modular construction site equipment, interactive planning tools, algorithmic resource planning, employee-focused human-robot interface, interconnected information flows from construction planning to the execution of construction work
  • Evaluation based on demonstration scenarios and economic considerations


The results of the project have been published in the Springer book IoC-Internet of Construction.

VDI-EE 2558

VDI-EE 2558 on construction process ontology was published at the beginning of November 2023. The expert paper deals with the superordinate linking of information models in the construction industry and thus represents an initial application guide for the use of ontologies in the construction industry. The expert paper makes the IoC's developments available to a wide range of users.

Open Campus Week

The final results of the Internet of Construction project were presented at the Campus West reference construction site on June 22 as part of the Open Campus Week. More than 200 interested parties from industry, research, politics and associations were present. The impressions were captured in the Open Campus Week movie.

Internet of Construction at digitalBAU

The results of Internet of Construction were presented at digitalBAU from 31.05. to 02.06. in Cologne. The researchers and developers of the Chair of Individualized Construction Production and involved industry partners presented the implementation of the project on the reference construction site at Campus West for the first time at the Startup stand 119/17 in Hall 5. The public interest for the project, which was also presented by Prof. Brell-Cokcan in her key note at the worldarchitecture forum, was great. Visitors were able to perform IoC developments of construction site logistics and assembly in real life on a scaled model with an AR application developed by students (Christine Lappe, Hannes Reuther and Chu Han Wu) of the master program Constructions&Robotics as a companion project in interdisciplinary teaching at RWTH Aachen University.
With our associated partners Bauforumstahl and Autodesk, results of the research on robotics in steel construction in the form of working aids and the IoC systematics are also made available in teaching to a wide audience in a wide variety of training levels.

Consortium meeting at Annen company

The thirteenth consortium meeting took place at the Annen company in Manternach. The consortium was shown impressive insights into timber construction. Mr. Annen demonstrated the possibilities of timber construction and individualized building production at the new production hall in Manternach. The new building is based on more than 7000 single parts with individual dimensions, which could be planned by digital tools in a high level of detail suitable for production. The presentation illustrates the potential of digitalization, which can be expanded in the future through IoC developments.

Assembly on Reference Site

The assembly of the IoC demonstrator took place on the Reference Site Campus West. Together with the companies Annen Holzbau, WURST Stahlbau, LEONHARD WEISS and Liebherr, the prefabricated steel and timber elements were mounted on the reinforced concrete columns. Based on the assembly, the developments of the IoC consortium could be tested and further developed under real conditions. The developments include, among others, the digital crane assistance system, the IoC ontology and automated construction progress recognition.

Steel construction demonstrator in action at Lamparter

The twelfth IoC project meeting was held at Lamparter in Kassel. On site, the application of the IoC steel construction demonstrator was presented under real conditions to the consortium during a hybrid event. The Chair of Individualized Construction Production and Robots in Architecture Research UG had tested the use of the flexible mobile robot platforms on site with Lamparter over a period of two weeks and had further developed it specifically for steel construction. Results are promising: The robot assists with assembly, for example by transporting and precisely positioning components.

IoC-Start of the Demonstrator

The first construction examination for the IoC demonstrator took place at the Reference Construction Site Campus West in October. Together with LEONARD WEISS GmbH & Co. KG, the IoC systematics for the reinforced concrete was examined under real conditions. The aim of the demonstrator is to validate the IoC systematics by integrating and testing cyber-physical systems on the construction site.

Together with swedish partners the EUREKA-Project Icon 4.0 (European Collaboration to extend the Internet of Construction towards Agile Construction 4.0) was started at the beginning of 2021. Icon 4.0 extends the IoC approach for construction 4.0 by considering a continuous digital information flow in the implementation of masonry construction. The Swedish-German collaboration thus enables a international and cross-building material view of the construction value chain within the European community for the IoC project.
