Zurich Zoo steel project collapse pushes two firms into debt moratorium

Two metal construction firms owned by Thomas Baltensperger have been placed under a provisional debt-restructuring moratorium. The District Court of Bülach issued the ruling on 23 December, affecting over 70 jobs. The move follows a dispute over a major project at Zurich Zoo.

The legal action stems from a contract to build the Pantanal aviary at Zurich Zoo. Baltensperger’s companies were responsible for supplying ten steel arches and a 1,400-ton grid. However, delays and rising costs led the zoo to terminate the collaboration.

The zoo had already secured four million Swiss francs in guarantees due to the setbacks. Despite the termination, further talks between the zoo and Baltensperger are scheduled for January 2026. The status of the aviary’s opening remains uncertain.

The moratorium allows Baltensperger’s firms to explore restructuring options while continuing operations. Creditors may agree to waive debts if employees’ wages and social security contributions are paid in full.

The court’s decision provides temporary relief for the companies and their workers. Negotiations in January will determine the next steps for the aviary project. The outcome will also impact the future of Baltensperger’s businesses and the zoo’s construction plans.
