Walli AG Ingenieure

What Walli AG Ingenieure does

Wälli AG Ingenieure is a Swiss engineering firm founded in 1949, headquartered in Arbon, and operating across three integrated divisions: Konstruktiver Ingenieurbau (structural engineering), Tiefbau (civil engineering), and Geoinformatik (geoinformatics). The firm is the official land surveyor for 31 municipalities in the cantons of St. Gallen and Thurgau, manages more than 150 utility cadastres and has delivered over 100 subprojects for SBB railway surveying. It serves cantonal and municipal governments, water utilities, transportation authorities, and selected private clients such as Metrohm AG, IWB Basel, Energie Wettingen, and Flughafen Zürich.

Its core technical capabilities span official land surveying, BIM, drone-based aerial surveying (eBee RTK), 3D laser scanning, geomonitoring (deformation, vibration, crack protocols per SN 640 312), and proprietary WebGIS platforms including AggloPortal, Gemeinde-GIS, Verbands-GIS, and LIGIS. The firm also distributes the ZoneScan AI acoustic leak detection system under a partnership with GUTERMANN AG, applying machine learning to continuously monitor water supply networks. The 2025 launch of ZoneScan AI extends the product portfolio into cloud-based, recurring-revenue infrastructure monitoring.

Wälli generates revenue through three primary streams: project-based engineering consulting services (civil, structural, geoinformatics), hardware sales and rental of measurement equipment via the messtechnik.waelli.ch portal, and recurring municipal consulting mandates for 15 municipalities. Distribution is via 14 regional offices across 7 Swiss cantons plus an e-commerce equipment channel; pricing is quote-based and project-specific. The firm is privately held with no external investors, parent company, or disclosed funding history.

Core offering

Wälli AG Ingenieure delivers integrated civil engineering, structural engineering, and geoinformatics services to Swiss municipalities, cantons, and enterprises — covering infrastructure planning, surveying, water/wastewater/transport systems, BIM, geomonitoring, 3D laser scanning, drone surveying, and WebGIS platforms. The firm also distributes and services measurement and leak-detection equipment (including ZoneScan AI) for water supply networks, and develops proprietary GIS software such as AggloPortal and LIGIS used by multiple Swiss cantons. Services are delivered through 14 regional offices across Switzerland, backed by over 75 years of accumulated geodata and cadastral management since 1949.

Product overview

Wälli AG Ingenieure operates as an engineering firm with three core divisions — Geoinformatik (Geomatics/GIS), Tiefbau (Civil Engineering), and Konstruktiver Ingenieurbau (Structural Engineering) — offering a portfolio of specialized products and services. In Geoinformatik, the key offerings include surveying services (official land surveying, construction surveying, railway surveying), geomonitoring (deformation measurement, vibration monitoring, crack protocols), 3D measurement (3D laser scanning, drone surveying), BIM services, WebGIS platforms (Gemeinde-GIS, Verbands-GIS, Unternehmens-GIS, LIGIS), utility cadaster management (water, wastewater, gas, electricity, telecommunications, district heating), and land management. The Tiefbau division covers traffic planning, road construction, wastewater/drainage systems, water supply with ZoneScan AI leak detection products, hydraulic engineering, and consulting services. Cross-divisional specialized products include ZoneScan AI (cloud-based permanent acoustic leak detection system), ZoneScan 850 and ZoneScan 820 (mobile noise loggers), Aquascan 610 and Aquascan 760T (wireless correlators), Fuji LC-5000 (correlator), vScan M and vLoc3-9800 (line locators), and Füllstandsensor (level sensor for sewage and flood monitoring). The Aggloportal is a GIS-based web application used across multiple Swiss cantons for managing agglomeration programs.
