What Ingenieurburo Lopp Planungsges. Mbh does

Ingenieurbüro LOPP Planungsgesellschaft mbH is a German engineering planning firm founded in 1990 in Weimar, specializing in water management and municipal infrastructure design. The firm delivers planning services across all HOAI (Honorarordnung für Architekten und Ingenieure) phases—from concept development and preliminary design through detailed planning, tender preparation, and construction supervision—for drinking water treatment plants, wastewater treatment facilities, flood protection systems, urban drainage, transportation infrastructure, and area development projects. Its technical backbone is an interdisciplinary engineering model combining water chemistry, bio-process engineering, civil engineering, mechanical and plant engineering, electrical and automation engineering, and architecture, with growing use of BIM and 2D hydraulic modeling. Notable project capabilities include the Berliner RÜB IV (18,000 m³ stormwater retention, 35 m deep), Klärwerk Ruhleben modernization (250,000 m³/day), Wasserwerk Allmendfeld (72,000 m³/day), and the Verbandskläranlage Arnstadt expansion to 140,000 population equivalent with 420 kW biogas CHP generation.

The firm is a family-owned private GmbH (commercial register HRB 102901 Jena, VAT DE150103992), wholly owned and managed since 1997 by brothers Dr. sc. techn. Hartmut Lopp and Dr.-Ing. Marcus Lopp, with additional leadership including Prokurist Maik Blankenburg and BIM expert Dr.-Ing. Gunnar Hädrich. Operations span three offices—Weimar (headquarters, Freiherr-vom-Stein-Allee 5), Berlin (opened 2018, Schaperstraße 18), and Dresden (opened 2024, Bertolt-Brecht-Allee 4)—serving clients across Thuringia, Berlin, Saxony, Hesse, and Brandenburg. Revenue is generated exclusively through professional services fees from project-specific proposals and public tenders; no revenue figure, headcount, or financial metrics are disclosed in available sources. The customer base is concentrated in the public sector, comprising municipalities (e.g., Stadt Weimar, Stadtentwässerung Dresden, Stadt Frankfurt), municipal water utilities (Berliner Wasserbetriebe), and water associations (Wasserverband Strausberg-Erkner, Zweckverband Arnstadt), with industrial water clients as a secondary segment. Go-to-market is sales-led via direct engagement with public-sector clients and participation in public procurement processes, supplemented by a project-portfolio-driven website and embedded YouTube content.

Broad incumbents

• Sweco: European engineering and architecture consultancy with a growing German presence in water and environmental infrastructure. Overlaps with LOPP in municipal water planning and flood protection, though with substantially greater scale.
• CDM Smith: Global water and environmental engineering firm with European operations providing planning, design, and program management for municipal water utilities. Comparable technical capability but larger international platform.
• Ramboll Group: Nordic-headquartered global engineering, architecture, and consulting firm with a strong German water practice. Competes with LOPP for municipal water and climate adaptation projects but at much larger scale with international resources.
• Dorsch Holding (Dorsch Gruppe): Large German engineering group covering water, environment, transport, and architecture with international reach. Competes for the same municipal water and wastewater tenders as LOPP but at significantly larger scale and broader service scope.
• Arcadis: Global design and consultancy firm with a substantial German water infrastructure practice. Provides overlapping water/wastewater planning capabilities to municipal clients, with broader geographic and digital capability footprint than LOPP.

Direct peers

• Weber-Ingenieure: Independent German engineering firm offering water, wastewater, and infrastructure planning services to municipalities and utilities. Closely comparable mid-sized specialist with similar HOAI service offering and public-sector focus.
• Ingenieurgesellschaft Dr. Siekmann + Partner: German water and wastewater engineering consultancy serving municipal utilities and water associations. Comparable specialist profile, regional office model, and HOAI-based service delivery.
• Björnsen Beratende Ingenieure: German engineering consultancy headquartered in Koblenz specializing in water, wastewater, hydraulic engineering, and infrastructure planning for public-sector clients. Directly comparable in service portfolio, customer base (municipal utilities), and HOAI-based delivery model to INGENIEURBÜRO LOPP.

Regional players

• Holinger: Swiss-headquartered engineering consultancy specializing in water, wastewater, and energy infrastructure. Comparable technical specialization and municipal-utility focus, but primarily serves Switzerland rather than competing head-to-head in Germany.

Others

• Gopa Tech / Gopa Consultants: German development and infrastructure consultancy with water sector capabilities serving public-sector clients internationally. Tangentially comparable as another German-rooted engineering services platform targeting water and infrastructure mandates, though with a more international development focus than LOPP's domestic municipal base.
