Drees & Sommer Switzerland

What Drees & Sommer Switzerland does

Drees & Sommer Switzerland (legal name: Drees & Sommer Schweiz) is the Swiss subsidiary of German partner-owned consulting firm Drees & Sommer SE, operating from four Swiss offices (Basel, Bern, Lausanne, Zürich) with approximately 250 employees, while the parent group employs roughly 6,500 people across 80+ locations worldwide. The Swiss entity was established in 2008 and delivers integrated consulting and implementation services under two pillars: Beratung (Consulting) covering strategy, workplace, digital services, risk, sustainability, urban/infrastructure, real estate, and technical consulting, and Realisierung (Implementation) covering client representation, general planning/EPCM, overall project leadership, and construction management. It serves institutional clients across three primary sectors — Real Estate, Infrastructure, and Industry — including public-sector bodies (e.g., Ostschweizer Kinderspital St. Gallen, FHGR, SBB), healthcare, education, hospitality (e.g., Locke am Platz), and industrial operators.

The firm's underlying technology stack centers on Building Information Modeling (BIM) and digital twin methodologies, building automation, smart charging/e-mobility infrastructure consulting, and Lean process optimization, packaged into named offerings such as BIM Solutions, Smart Charging, and Lean Solutions. These digital tools are embedded across both the advisory and implementation service lines to coordinate project delivery and produce digital replicas of buildings. Proprietary research publications — including the annual Trendstudie Real Estate Management (303 DACH respondents in 2025) and the Real Estate Service Monitor — provide market intelligence assets that support advisory positioning in the Swiss real estate and facility management markets.

Drees & Sommer Switzerland generates revenue through professional services engagements, combining advisory/consulting fees with project-realization contracts billed on a project basis. Pricing is not publicly disclosed; the firm does not offer subscription tiers or self-service channels. Go-to-market is exclusively enterprise field sales targeting large institutional clients via direct advisory relationships, RFP participation, competitive tenders, and longstanding accounts. Strategic alliances with technology partners such as Siemens Schweiz and architectural firms such as Boltshauser Architekten extend delivery capacity and support competition-driven project wins.
