Abstract
This contribution presents the prerequisites in the construction process of a bio-based experimental pavilion. A first challenge, is to define tolerances and implicitly measurement tolerances for these materials. After defining them, the focus is set on what can be achieved if geometric quality control is only conducted during the assembly process. Despite using high-end total stations and terrestrial laser scanners in this process, the final pavilion showed discrepancies to its model. In some cases, these were larger than the given tolerances, showing on one side what tasks can be achieved with these instruments and on the other, drawbacks that remain a challenge in bio-based segmented experimental buildings. Finally, an improved workflow is suggested.

This paper used BioMat pavilion 2018 as a case study for discussion about geometric quality of biocomposite building elements. We would like to acknowledge for support within pavilion fabrication as well as geometric quality study.
Fabrication:
Pavilion Fabrication was supported by German Agency for Renewable Resources (FNR) under the Ministry of Food and Agriculture (BMEL) by project “Bioprofile: (co-)extruded profiles from bioplastics reinforced with plant residues.”
This project is also an associated project (AP 08) with Cluster of Excellence Integrative Computational Design and Construction for Architecture (IntCDC) partially supported by the DFG under Germany’s Excellence Strategy—EXC 2120/1—390831618.
We thank all students, employees, technicians and agencies involved in this project. This work was the direct result of cooperation between around 40 architecture students over two semesters participating in the (Flexible Forms) Design Studio in the semesters: WS17/18 and SS18 supervised by Hanaa Dahy, the director of BioMat group at ITKE with her team: Jan Petrs, Piotr Baszynski and Michaela Mey, with the support from the University of Stuttgart and the Baden-Württemberg Foundation. Financial support was from the German Agency for Renewable Resources (FNR) under the Ministry of Food and Agriculture (BMEL), and scientific cooperation took place with Fraunhofer-Institut für Holzforschung (Fraunhofer WKI) and industrial partners Mathias Stange ETS and Profine GmbH in the framework of the Research Project (BioProfile) FKZ 22021516. International collaboration has taken place with the Technical University Eindhoven in the Netherlands (TU/e) – Department of Built Environment Prof. Patrick Teuffel, Dr. Arjan Habraken and M. Sc. Dirk Bos, in addition to local collaboration with various institutes of the University of Stuttgart, including the Institute of Construction and Structural Design (KE) – Prof. Ulrike Kuhlmann and Mr. Janusch Töpler as well as the Institute of Engineering Geodesy (IIGS) Prof. Volker Schwieger and Gabriel Kerekes. Wooden beams were fabricated and supported by Burgbacher Holztechnologie GmbH with assistance of Mr. Steffen Haller, weathering resistant coatings were provided by Hexion Stuttgart GmbH.
Geometric quality study:
The study was a supported by Research Project (06) of the Cluster of Excellence Integrative Computational Design and Construction for Architecture (IntCDC). It is partially supported by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany’s Excellence Strategy EXC 2120/1-390831618.
