Broad incumbents

• Arcadis: Global design and consultancy with Swiss presence in sustainable buildings, energy transition, and mobility infrastructure. Adjacent competitor for large institutional and sustainability-driven mandates in Switzerland.
• AFRY: Global engineering, design, and advisory firm with a substantial Swiss footprint. Overlaps with S+R on energy, building electrification, and renewables consulting, but at significantly larger scale and broader geographic reach.
• Sweco: European engineering and architecture consultancy with Swiss offices. Active in building services, energy, and electrification — competing for larger mandates that S+R cannot self-execute.
• Ramboll Group: International engineering, architecture, and consulting company with Swiss operations covering buildings, energy, and sustainability. Competes for large institutional and infrastructure clients in Switzerland.
• EBP (Ernst Basler + Partner): Zürich-based Swiss engineering and consulting firm active in energy, infrastructure, and building projects. Broader portfolio and larger scale than S+R but competes for similar client engagements including public-sector sustainability work.
