LEHMANN + PARTNER

What LEHMANN + PARTNER does

LEHMANN + PARTNER GmbH is a German road condition assessment and infrastructure management specialist headquartered in Erfurt, Thuringia, operating three domestic offices (Erfurt, Dresden, Konstanz) with approximately 67 qualified employees plus four apprentices. The company is a subsidiary of the French GINGER Group (acquired 2017), a diversified engineering services conglomerate with operations in Germany, France, Poland, and the UK. Founded around 1994, LEHMANN + PARTNER claims 31 years of road-surveying expertise and captures roughly 40,000 route kilometers annually across Germany, with additional project activity in France, Poland, the UK, China, Norway, Australia, and India.

The core offering combines proprietary mobile mapping hardware with proprietary software. The hardware stack consists of several specialized measurement vehicle platforms — IRIS (including IRIS 13 and IRIS 15), ATLAS+, and S.T.I.E.R. — fitted with LiDAR laser scanners, panoramic and high-resolution cameras, GPS, inertial navigation, and surface lighting. Data capture is processed through DeepDTX, an AI-based computer vision system that detects cracks, potholes, and surface defects at millimeter precision. On the software side, SIBLP manages road information databases and integrates algorithms for forming homogeneous condition sections developed through BASt-funded research projects (reports S 184 and S 195); LP Portal is a web-based pavement management and customer portal. A current R&D initiative, PoRaKiS, integrates ultra-wideband ground-penetrating radar with the multisensor stack, in collaboration with TU Ilmenau and Fraunhofer IZFP.

LEHMANN + PARTNER monetizes primarily through professional services — on-site road condition surveys, inventory documentation, bearing-capacity measurements, and consulting for municipalities and public-sector clients — supplemented by subscription/maintenance revenue from SIBLP and LP Portal software and data analysis services. Go-to-market relies on direct enterprise field sales to municipal and county governments (Außendienst) augmented by conference presence (Infratech, 3D Forum Lindau, Kommunale, ERPUG, Deutscher Straßenkongress) and customer webinars/workshops. The named customer base consists almost entirely of German municipalities (Landkreis Bautzen, Stadt Oldenburg, Stadt Freising, Flughafen Stuttgart, Stadt Rhede, Stadt Hemer, and ~10 others), with project-level repeat engagements observed (e.g., Glienicke after 10 years). Pricing is custom-quoted per project; no public pricing or disclosed financials exist.

Scale indicators5 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Topcon Positioning: Major provider of mobile mapping, surveying, and road construction positioning systems with significant global footprint. Comparable to L+P in road data collection technology but operates across many more verticals (construction, agriculture, geospatial) at a larger scale.
• WSP Global: Large global engineering consultancy with road infrastructure and pavement management practices, including data collection and asset management for transportation agencies. Overlaps with L&P in condition assessment services but at much larger scale and as part of a broad engineering portfolio.
• Stantec: Global engineering, architecture, and infrastructure consultancy with transportation and pavement management practices. Overlaps with L+P on the consulting and asset management side, while operating at much larger scale and across many more infrastructure verticals.
• Fugro: Global geo-data and asset integrity specialist with a large road and rail infrastructure surveying practice using mobile mapping, LiDAR, and ground-penetrating radar. Significantly larger scale than L+P and serves as the dominant broad incumbent in road infrastructure data collection globally.

Direct peers

• Greenwood Engineering: Denmark-based specialist in high-speed road profiling and surface measurement equipment (Profilograph, Laser RST). Comparable European provider of vehicle-mounted road condition measurement systems for highway and municipal customers.
• Mandli Communications: US-based specialist in road condition data collection and pavement assessment using mobile mapping vehicles and AI-based crack detection. Most direct competitor in the niche that L+P operates in, with similar business model of vehicle-mounted LiDAR/camera surveys for municipal and DOT customers.
• Dynatest: Denmark-founded global provider of pavement evaluation services and equipment, including falling weight deflectometers and high-speed profilers. Directly comparable in road condition measurement services for transportation agencies, overlapping with L+P's bearing capacity and surface assessment offerings.
• Pavemetrics (Mandli): Canadian automated pavement inspection systems provider (now part of Mandli) specializing in 3D laser-based road surface sensors and AI-driven distress detection. Direct overlap with L+P's DeepDTX-style computer vision for millimeter-level crack and pothole detection.

Others

• Trimble Inc. Large geospatial technology company offering mobile mapping systems, survey sensors, and infrastructure asset management software. While not a direct service competitor, Trimble's hardware/software stack overlaps with L+P's measurement technology portfolio across a much broader customer base.

Regional players

• ARRB Systems (Australian Road Research Board): Australian road research and technology provider with road condition assessment services and intelligent transport systems. Comparable technical offering to L+P in road profiling and data collection, but primarily serves Australia/New Zealand rather than competing directly in Europe.
