What Stage planning by Walter Kottke Ingenieure does

Bühnenplanung Walter Kottke Ingenieure GmbH (BWKI) is a German private engineering consultancy founded in 1987 and headquartered in Bayreuth, Bavaria. The firm plans, specifies, and supervises stage machinery, event technology, lighting, AVMI (audio/video/media/communication), stage wood and textiles, and accessibility systems for theaters, opera houses, concert halls, congress centers, and heritage venues. Its client base is concentrated in the public cultural sector — state and municipal theaters, opera houses, and UNESCO heritage sites — across the DACH region and select international markets including Austria, Switzerland, the Czech Republic, Latvia, Russia, France, Italy, and Colombia. The firm operates as a family-owned business (Familienunternehmen) led since November 1, 2023 by founders' representatives Daniela Kottke and Benjamin Neuen alongside founder Walter Kottke.

The firm's core technology is built on a multidisciplinary engineering bench spanning mechanical, electrical, structural, and theater technology disciplines, with active participation in DIN committees, DTHG/OETHG/VDT/VDI/svtb professional associations, and the Bayerische Ingenieurkammer-Bau. Proprietary engineering solutions developed for landmark projects include a two-part iron curtain for the UNESCO-listed Markgräfliches Opernhaus Bayreuth, a hydraulic wheel-change and automatic rope-tensioning system for the Bayerische Staatsoper München's stage wagons, low-noise understage machinery for Deutsche Oper Berlin (35–40 dB(A) in front rows), a 32 m transport turntable with integrated performance turntable for Musiktheater Linz, and relocatable counterweight winch systems for Festspielhaus Bregenz. The firm maintains long-cycle architect-of-record partnerships with Marte.Marte Architekten (Bregenz), Dietrich|Untertrifaller (Stadthalle Wien), Staab Architekten (Wagner Museum), and Terry Pawson/Architektur Consult (Musiktheater Linz), and employs a dedicated acquisition department plus PR function.

BWKI generates revenue through project-based engineering planning services billed under Germany's HOAI fee framework (Honorarordnung für Architekten und Ingenieure), spanning concept studies, needs analyses, preliminary and detailed planning, tendering, and construction supervision across all Leistungsphasen. Pricing is not publicly disclosed and is negotiated per project through competitive public-sector tendering and direct engagement with theater directors, technical directors, and municipal building authorities. Customers include marquee references such as Bayerische Staatsoper München (€11.0M net multi-phase engagement, 2004–2016), Deutsche Oper Berlin, Schauspiel Frankfurt, Festspielhaus St. Pölten, Oper Graz, World Conference Center Bonn, and the new Konzerthaus München (1,800-seat). Marketing is conducted via the firm website, trade press (BTR, etNow!), and professional association participation rather than consumer channels. The firm is currently 30–35 employees and was awarded the Exportpreis Bayern 2025 for its international business operations.

Direct peers

• SBS Bühnentechnik: Dresden-based execution and installation partner for theater and stage machinery projects. Engaged as BWKI's subcontractor on the Tiroler Landestheater Innsbruck project, operating in the same German-speaking theater-technology ecosystem with overlapping customer base.
• GFT Gesellschaft für Theatertechnik: German planning and consulting office for theater technology and venue infrastructure serving public cultural institutions across DACH. Directly comparable to BWKI in offering multidisciplinary theater engineering planning services (HOAI-aligned) for theaters, opera houses, and multi-purpose halls.
• ArtSceno: Geneva-based specialist theater and event technology planning consultancy. Identified in BWKI's own partnerships as the lead planning office on CICG Geneva hydraulic-system project with BWKI as sub-planner, making it a directly comparable DACH-region specialist in stage and event technology engineering.
• Waagner-Biro Stage Systems: Austria-headquartered specialist in stage machinery, scenic technology, and complex theater engineering. Listed as execution partner on BWKI's Freiheitshalle Hof retractable-seating project and serves the same public-sector theater and cultural-building market across DACH.

Broad incumbents

• Gala Systems: Canada-based designer and manufacturer of stage machinery (elevators, turntables, orchestra lifts, wagon systems). Competes in the same category of understage and upper-stage machinery that BWKI plans, but delivers integrated hardware-plus-controls solutions rather than pure planning services.
• Wenger Corporation: US-based manufacturer of theater equipment including staging, acoustics, and audience seating. Serves the same end customers (performing-arts centers and concert halls) globally but competes as an integrated product-and-installation incumbent rather than a planning consultancy.
• Salzbrenner: German full-service provider of stage management systems, audio, video, and intercom solutions for theaters and broadcast. Overlaps with BWKI's AVMI scope but as a broader systems integrator that supplies and installs rather than plans under HOAI service phases.
• Bosch Rexroth (Stage Technologies): Global stage-technology provider (incorporating Stage Technologies) supplying hydraulic and electric stage machinery plus control systems. Cited as equipment supplier on the CICG Geneva project and competes for the same large-scale theater modernization contracts as BWKI but as an integrated manufacturer-installer.

Emerging players

• ASM Steuerungstechnik: German specialist in stage and theater automation/control systems. Addresses adjacent scope within BWKI's service envelope (Bühnenmaschinerie control), typically for mid-sized venues, and represents a partial-overlap emerging specialist rather than a full-service planning competitor.

Others

• Gerriets GmbH: German manufacturer and supplier of theatrical textiles, stage drapery, and acoustic curtains. Adjacent supplier-side peer to BWKI's stage wood/textiles planning scope, often specified within BWKI's project specifications rather than competing for the planning contract itself.
