After theoretical considerations, a research model was developed and empirically tested. The results show that there are differences in the preferences of niche providers and market leaders, such as importance of website features and the breadth and depth of a balanced product portfolio of customers. In addition, the study shows how individual factors can be analyzed in an online shop and which alternative courses of action can be derived.

Tagungsband der Fünften Jahrestagung der Gesellschaft für Bautechnikgeschichte 10. bis 11. Juni 2021 N2 - Betrachtet wird die geometrische Konzeption der Gewölbe der von Balthasar Neumann entworfenen Wallfahrtskirche Vierzehnheiligen. Ausgehend vom gebauten Objekt und basierend auf 3D-Scanningdaten, werden mithilfe der Methode des Reverse Geometric Engineering die geometrischen Eigenschaften des Gewölbes untersucht und die Konzepte rekonstruiert, die bei der Planung zur Anwendung gekommen sein müssen. Dabei werden die Abteikirche Banz und die Hofkirche der Residenz Würzburg als Vergleichsbauten mit einbezogen. Die Entwurfsmethoden werden in ihrem Zusammenhang mit den zeitgenössischen Traktaten der Stereotomie und Architektur, sowie mit bekannten Planungspraktiken bei geometrisch komplexen Bauten betrachtet; dabei wird auch der Bezug zu den Gewölbeentwürfen des italienischen Barockarchitekten Guarino Guarini diskutiert.

Volume 2 N2 - Johann Dientzenhofer’s Banz Abbey Church (1710-1718) and Balthasar Neumann’s church of Vierzehnheiligen (1743-1772), both located in Upper Franconia (Germany), are characterised by their masonry vaults, sequences of oval domes separated by double-curved arches. This Late Baroque architecture has been called “Guarinesque”; however, the conceptual connection between the vaults and Guarino Guarini’s architecture remains to be thoroughly investigated. This paper resumes the discussion about the geometric definitions of these vaults using the modern methods of geometric analysis and reverse geometrical engineering, based on 3D laser scanning. The analysis of these scans reveals a design process based on plane circle segments and ovals, while more complex geometric procedures are not necessary to describe the vaults. Further, the relationship between these designs and the procedures of geometric design described in the treatises of stereotomy since the 16th century can be shown. On this background, the relation to Guarini’s Architettura Civile (1737) is discussed.

From his extensive architectural oeuvre, a group of six church buildings with geometrically complex forms stands out, recognised by architectural historians as particularly innovative and influential. These churches, located in Bohemia (Czech Republic), and often collectively referred to as the ‘radical’, ‘dynamic’, ‘Guarinesque’, or simply ‘Bohemian’ group, are: St. Joseph in Obořiště (1702–11), the Castle Church in Smiřice (1702–11), St. Nicholas in the Lesser Town of Prague (1703–11), St. Clare in Cheb (1707–11), St. Margaret in Břevnov (1708–16), and the Church of the Holy Assumption in Nová Paka (1709–24). The brick vaults of these six buildings, sequences of oval domes and double-curved vault areas, are of particular interest for building research. In this study, the geometric design of the vaults of Dientzenhofer’s ‘radical’ churches is documented, analysed, and compared using 3D laser scans of the buildings as primary source. The 3D models generated from the scans enable a geometric analysis through the method of reverse geometric engineering, breaking down the vaults’ complex three-dimensional forms into their basic two-dimensional components: segments of circles with different radii and orientations, curved in one or two directions. These forms can be found in the architectural and stereotomic treatises that were widespread at the time. By comparing the vault geometry of the six churches with each other and with the geometric concepts discussed in the treatises, general statements can be made about the architect’s design choices. On the basis of this investigation, hypotheses are made about the design and underlying geometric ideas of the vaults of Dientzenhofer’s ‘radical group’, and the results are placed in context.
