Description & Project Overview
Service Oct 30, 2026 | Renovation of Lake Constance Arena service offer electrical planning: The Bodensee Arena is an important sports, leisure and event facility in the Kreuzlingen-Konstanz region. The facility, which has existed since 1978 and has been expanded several times, is in need of extensive structural, technical and operational renovation. The city of Kreuzlingen is planning to renovate the existing facility and convert the current outdoor ice rink into a training hall.
The existing building structure should continue to be used as far as technically and economically sensible. The implementation takes place in stages, taking ongoing operations into account. With the referendum on September 28, 2025, the investment loan of CHF 26.7 million was approved.
This forms the binding financial upper limit for the entire project. The planning must be consistently developed according to the design-to-cost principle. As part of a selective service quotation process with prequalification (phase 1) and subsequent offer (phase 2), a qualified electrical engineering office is sought for electrical planning, including photovoltaic systems.
The mandate covers the services in accordance with SIA 108 for phases 31–53, from project planning to commissioning of the high- and low-current systems as well as the photovoltaic systems. Particular challenges are the different levels of renewal of the existing electrical installations, the renewal of the electrical lines and distributions as well as the integration of the photovoltaic systems into the electrical infrastructure. The planning must take into account the different uses and operating conditions of the existing Lake Constance Arena and the new training hall and enable phased implementation while preserving ongoing operations as much as possible. The interfaces to the separately commissioned HVAC and building automation, to the refrigeration system planning and the architecture must be coordinated and secured at an early stage
