The focus during the development of the 45 m tall high voltage pylon was to use as little material as possible for the mounting process, resulting in a four-branch pylon resembling a squatting fox. As part of an international competition, PART Architects were selected to design and build this dominant deviation pylon, which sits on a prominent site adjacent to a nature reserve creating a towering new landmark in the region.

We were involved in the conceptual planning for the structural engineering of the pylon. A parametric model to control the axes’ length, direction and relative direction based on geometric and structural requirements was generated to evaluate various design options. Initial investigations with the architects focused heavily on timber construction methods, with the pylon finally being constructed in steel. The cross-section profiles were optimised according to the structural capacity of each segment, which not only creates an organic aesthetic but also reduces material usage.
