WELCOME TO SCHNIERING GMBH, THE LEADING PROVIDER FOR ROAD CONDITION MONITORING AND ASSESSMENT
When it comes to measuring the condition of roads and cycle paths with high-speed measuring systems and their subsequent evaluation, we are the number 1 in Germany and Switzerland and one of the leading companies in Europe. The processing of research projects as well as the customised production of measurement vehicles represents another mainstay.
OUR SERVICES
50 years of experience in this field make us a strong national and international partner for the public administrations of the federal and state governments, counties and municipalities as well as the private sector.
The data collected by our fast-driving measurement systems and then individually evaluated represent an essential basis for road maintenance and management. Comprehensive quality assurance, which includes the annual certification of the measurement vehicles by the German Federal Highway Research Institute (BASt), ensures the reliability of the results.
This allows maintenance and construction measures to be planned effectively, investments to be optimised in terms of time and costs, and fixed assets to be verifiably valued.

CONDITION MONITORING ON ROADS
Evenness measurements
Evenness is measured in longitudinal and transversal direction according to ” Eben – Berührungslose Messungen“. High-precision laser measuring systems are used for this.
Skid resistance measurements Macrotexture measurements
Skid resistances are recorded using the side force measurement method in accordance with “TP Griff-StB (SKM)”. The macrotexture is recorded in accordance with DIN EN ISO 13473-1.
Detection of surface damages
Damages on the carriageway are recorded with the aid of artificially illuminated surface images and then evaluated for defined condition characteristics in accordance with the state and contract-specific regulations such as ZTV ZEB-StB.
Recording of roadway images
During the condition monitoring, images of the road space, so-called roadway images, are taken. The front, side and rear views are used, among other things, for condition evaluation and inventory data collection.
CONDITION MONITORING ON CYCLE PATHS
Evenness measurements
Evenness is measured longitudinally in accordance with „TP Eben – Berührungslose Messungen“. High-precision laser measuring systems are used to reliably and precisely detect heave and subsidence, e.g. due to root ingrowth, in the left and right rolling lanes of the measuring vehicle.
Detection of surface damages
Damages on the cycle path are recorded with the help of artificially illuminated surface images and subsequently evaluated for defined condition characteristics. The indicators not only differ according to the construction method asphalt, concrete and pavement, but also consider riding comfort restrictions.

BENEFIT FROM OUR SERVICES
Certified process conformity
Adherence to the processes defined by the rules and regulations ensures comparability between different measurement campaigns and enables medium- to long-term maintenance management.
Manufacturing of customised measurement systems
Decades of experience in the construction and use of measurement vehicles combined with a high level of vertical integration through in-house hardware and software development.
Measurements in the area of Construction and functional construction contracts
Object-related measurements of evenness, skid resistance and substance characteristics within the framework of (functional) construction contracts in accordance with regulations. Delivery of the results also as customer-specific documentation.
Objective documentation of the road condition
Certified and standardised measurement procedures provide objective condition data supplemented by expressive image material.
Quality assured results
Ensuring data quality through many years of experience and extensive quality assurance measures (BASt approvals, ISO 9001 certification, in-house / external monitoring, external quality assurance, etc.).
OUR MEASUREMENT SYSTEMS
Schniering GmbH has one of the most extensive vehicle fleets in the European market for condition monitoring with fast-moving measurement systems.
All measuring vehicles are equipped with measuring technology designed and developed in-house, which enables high reliability and operational capability.
This and our decades of experience and performance in the field of condition monitoring and assessment enable us to operate a fleet of vehicles with which we can economically and comprehensively meet project-related customer requirements.
In addition, we have a variety of in-house developed programmes for the evaluation and preparation of the collected data. This enables us to guarantee high-quality and timely provision of the data.
ARGUS®
Multifunctional measuring system for fast-driving detection of longitudinal and transverse evenness (TP1a and TP1b) as well as substance characteristics / surface damage (TP3) in accordance with “ZTV ZEB-StB” „TP Eben – Berührungslose Messungen“. Our ARGUS® measuring systems are inspected and certified annually by the German Federal Highway Research Institute (BASt).
SKM
Measuring system for the fast-driving detection of skid resistance (TP2) and macrotexture. Skid resistance is measured using the side force measuring method (SKM) with certified measuring tyres from the German Federal Highway Research Institute (BASt). Our SKM measuring systems are checked and certified annually by the BASt.
ARGUS®-Agil
Multifunctional measuring system for the fast-driving detection of longitudinal evenness (TP1a) in the left and right wheel path as well as substance features / surface damage (TP3) on cycle paths. In addition, the acquisition of the macrotexture is possible.
Customised
Customised production of multifunctional measuring systems and skid resistance measuring systems or their subcomponents for the high-speed recording of longitudinal and transverse evenness (TP1), skid resistance (TP2), substance characteristics / surface damage (TP3) and for recording track images.
VISUALIZATION
The STRADIVARI® programme system is available for the visualisation of the recorded data and images.
Based on the representation of the digitised road or cycle path network, total, partial or even individual values can be visualised via colour information in the respective section.
The underlying route and surface images can be called up with a “mouse click” on the respective section. Virtual travels and image-based situation analyses can thus be carried out quickly and easily. Configurable route and raw data bands for the selected routes as well as frequency distribution diagrams round off the possibilities.
