BATJ SA

What BATJ SA does

BATJ SA is a Geneva-based acoustics consulting firm (bureau d'étude) founded in 2017, specializing in architectural, environmental, and industrial acoustics. The firm is led by founder and managing director Thomas Juguin and operates with a team of approximately six acoustic engineers and architects. Its service portfolio spans five core domains: building acoustics (airborne and impact noise isolation, technical installation noise under Swiss standard SIA 181), room acoustics (DIN 18041 and SUVA compliance), environmental acoustics (OPB and LPE-related outdoor sound propagation), vibration analysis, and construction site noise monitoring using Norsonic Class 1 sound level meters and Syscom MR3000 vibration systems. Specialized sub-services include heat pump (PAC) noise circle form processing under FWS Cercle Bruit procedures and raw earth construction acoustic testing.

The business model is professional services consulting, with revenue generated through project-based study mandates billed per engagement scope, plus a fixed-fee PAC noise form service. Go-to-market is sales-led, relying on direct client engagement with architects, developers, and construction firms, supplemented by professional referrals, reference projects, and participation in industry normalization activities, congresses, and academic teaching at HEPIA and HEAD. Customer segments span schools/daycares, administrative and institutional buildings, mixed residential, hospitality, and wood construction projects, all within a primarily Geneva and Swiss geographic footprint. The firm differentiates through deep regulatory expertise, BIM capability, multi-label building certification experience (Minergie, DGNB, BREEAM, WELL, LEED), and HEPIA laboratory access for material testing.

Broad incumbent: large multi-disciplinary player that competes with BATJ on large institutional mandates where single-vendor accountability is preferred.
• WSP Global: Global professional services firm with an acoustics and vibration practice delivering noise and vibration services as part of integrated design mandates. Broad incumbent: offers overlapping capabilities but bundles them into a wider portfolio rather than specializing in pure-play acoustics.
• Ramboll: Global engineering, architecture and consultancy firm with an acoustics and noise practice operating across Europe. Broad incumbent: offers overlapping capabilities to BATJ on building and environmental acoustics, but as part of a much wider services portfolio.
