MONITORING CHANGES IN THE SUBSOIL AND IN BUILDINGS

Geological measurement technology: The use of highly sensitive measurement systems to prevent damage and optimise construction execution

In the context of many construction activities – within the fields of building deconstruction, special civil engineering, well and sewer construction – increasingly highly sensitive measurement systems are used for geotechnical purposes (geological measurement technology) and for construction engineering uses (construction measurement technology). Through these, the smallest changes in the subsoil (and also in constructions) can be monitored, critical changes and loads can be recognised at an early stage, and negative effects can be  avoided safely.

Geological measurement technology in construction

Potentially damaging effects are first revealed through our geotechnical and construction engineering assessments. We first coordinate the collaboration of planners, officials and executing companies as the basis for the use of construction and geometric technology. Often, the complex interaction between the construction soil and the building is underestimated, as are the possible consequences. Finally, for many construction projects, especially in inner city locations, possible negative influences cannot be calculated with sufficient accuracy.

Reliable monitoring and management of construction measures and avoidance of damage require measurements, such as those in accordance with DIN 1054 observance methods, specific standards (DIN 4150, vibrations during construction, DIN 4107, and others) or regulations (AVV construction noise, among others). Furthermore, knowledge gained from geological measurement technology can serve to optimise the construction process and provide secure documentation.

 

 

Typical areas where construction and geomeasurement technology are used:

  • Measuring settlement/lifting in buildings and subsoil
  • Checking slopes/tipping for buildings and subsoil
  • Deformation of construction systems such as landfills, earth dams and trenches
  • Terrain movements on slopes, landslides, etc.
  • Crack monitoring in buildings
  • Vibrations in buildings and infrastructure facilities
  • Monitoring of wells and groundwater

 

Skills and cooperation

In addition to comprehensive engineering experience and expert management, aspects such as the design, installation, configuration and the operation of hardware and software in geological measurement technology require our professional attention. Our automatic measurement systems include the fastest-possible alerts sent by SMS/email as standard, providing secure data transmission and transparent presentation of measurement data over Internet connections from the geological measurement systems. Regular monitoring by remote access and on-site are an essential part of our quality assurance. We ensure reliable monitoring around the clock and in all locations.

Close collaboration and exchange of experience with market-leading manufacturers, such as Glötzl Gesellschaft für Baumesstechnik mbH or GGB Gesellschaft für Geomechanik und Baumesstechnik mbH , additionally contribute to continuous further development and adaptations to our geological measurement technology.

 

 

Measurement systems and applications

In addition to a variety of additional technical solutions, we provide the following measurement systems for the most-frequently occurring applications in geological measurement technology:

  • Electronic hose scales to measure settlement in buildings, such as in the case of adding storeys, re-foundations, underpinning and anchoring.
  • Digital tilt meters to monitor tilting of buildings with gable guardrails, underpinning, etc.
  • Inclinometers to monitor construction trench walls and hanging.
  • Anchor force measurements for back-anchored construction walls.
  • Soil pressure measurements for landfill and load redistribution, such as earthworks and large silos
  • Pore water pressure measurements, such as to monitor water contents in construction trenches
  • Groundwater level measurements in wells and groundwater measurement locations
  • Vibration measurements as per DIN 4150 (triaxial geophones, GSM loggers)
  • Noise level measurements as per AVV Baulaerm [Construction Noise Regulation] for short-term deployment and continuous monitoring for demolition and construction activities
  • Geodetic height and position dimensions for neighbouring buildings, retaining walls, etc.
  • Automated tachymeter for constant, 24-hour measurement of construction projects to monitor height and position
  • 3D laser scanning and photogrammetry for digital capture of surfaces, such as for façade brackets

Our geomeasurement technology services

We provide all the services required for measurement monitoring:

  • Create measurement concepts and plans
  • Define alarm plans and action plans
  • Agreements with officials for demolition and construction permits
  • Coordination with construction supervisors, static engineers and implementing companies
  • Installation and operation of measurement systems
  • Monitoring and expert construction supervision
  • Preparation and assessment of measurement results
  • Create technical reports and expert assessments with geotechnical and construction engineering assessment of measurement results

Dust, noise and vibration emissions at building sites

For demolition and underground construction work, especially in inner city areas, typical emissions such as dust, noise and vibrations can have many negative effects on the people in the vicinity, on surrounding buildings and technical systems. Using relevant monitoring systems, the automatic noise and vibration measurements are continuously monitored, and dust precipitation is measured, which helps to effectively prevent negative impacts and damage. Since exceedances are directly felt on the site and in real time, one can react immediately and effectively to prevent further potential damaging effects in a timely manner.
