Heritage Buildings & Assets

Heritage buildings and assets are items that have contributed to a nation’s society, knowledge, and/or culture. Because of this it is incredibly important that they are valued and preserved in a state that is as close to original as feasibly possible. Monitoring of heritage buildings and assets is important in order to better understand how they behave as they are generally old, fragile, built using materials that may have decayed over time or may not have been to the standard that we are used to nowadays, and built on unknown foundations and/or ground conditions.

Monitoring listed structures and heritage buildings demands innovation to produce monitoring systems that can be installed without effecting the original structure.  Successful monitoring and surveying of these traditional sites offers preservation and protection, either during maintenance works or everyday use. We understand this and will work to design and implement a discreet and thorough monitoring scheme that can be affixed to the building or asset with minimal visual or physical impact. We also understand the importance of making good upon removal of the instrumentation.

Our bespoke monitoring plans can assess what external factors may cause damage and recommend suitable instrumentation to ensure the structure remained undisturbed. Quantities often measured in heritage work include vibration, pressure, loading, tilt and environmental factors.

Environmental Parameters

Environmental Parameters

Environmental Parameters

The assessment of environmental quality and parameters on a project can assist the construction phase and protect both people and structures from harmful effects. Environmental parameters have a huge range, from weather conditions to air and water quality. Through use of the correct equipment, we can install, monitor, and analyse the effects of the natural environment in engineering applications.

Environmental monitoring encompasses measuring a variety of quantities such as noise, temperature, humidity, dust, light, water and air quality. This differs from structural monitoring which is based on movement rather than environmental quality.

Utilities & Infrastructure

Utilities & Infrastructure

Utilities & Infrastructure

Infrastructure is the fundamental facilities and systems that serve a country, city, or other area, which include the services and facilities necessary for the economy to function. The term infrastructure encompasses utilities.

Utilities are the basic services provided to the public; electricity, natural gas, water, sewage, telephone, and transportation. Failure of the aforementioned can be costly and damaging to a country’s economy. In a lot of developed countries the infrastructure is ageing and in need of repair or replacement.

Data obtained from monitoring infrastructure can be interpreted and used within asset plans, maximising the lifespan of the asset, assisting with planning when and where repairs may be required, and giving a forewarning of impending failure, effectively creating ‘Smart Infrastructure’.

The following are examples of infrastructure we can monitor:

  • Roads
  • Railways
  • Canals
  • Harbours & Docks
  • Airports
  • Sewers & Pipelines
  • Pylons & Masts
  • Wind Turbines
  • Power Plants
  • Water Treatment Works

Dams

Dams

Dams

Different dam structures require different monitoring solutions and finding the ideal instrumentation for each dam is important to gather suitable data. Rigid concrete dams such as gravity, arch and buttress variants will require more structural monitoring solutions looking primarily at deflections and loads. Earth dams, embankments and rock-fill dams demand a more geotechnical monitoring plan focused on ground movement and stability.

We can produce comprehensive monitoring programs for short- or long-term monitoring of dam structures to record real-time data and provide project security.

Excavations & Retaining Walls

Excavations & Retaining Walls

Excavations & Retaining Walls

Monitoring retaining structures such as excavations is key in guaranteeing safety and predicting the dynamic behaviour of the surrounding ground. It also helps avoid overly conservative design approaches, and acts as a guideline to ensure that design conditions are met. Early warning signs can be detected by monitoring systems activating trigger alarms for measured quantities.

By measuring displacements in retaining structures, our monitoring solutions provide assurance of structural stability. Instrumentation tailored towards tilt, deflection, stress and strain is typically used to assess these types of structure and their surrounding ground.

Pile Load Tests

Pile Load Tests

Pile Load Tests

Pile testing acts as a quality control measure and validates design calculations, which play an important role in foundation design improvements in construction. Through use of load and deflection monitoring equipment, pile tests can be accompanied by accurate data guiding testing and reducing risk. Pile loading, whether is it static or dynamic, and pile integrity can be monitored continuously in real-time throughout the testing phase.

Pile testing generally requires load cells, displacement monitoring and strain gauges to quantify forces acting on the pile.

Mines

Mines

Mines

Safety is critical in mine work, and by taking a holistic approach through monitoring, emerging hazards can be identified and mitigated. The number of hazards present in mines is greater than many other environments, so comprehensive monitoring systems are crucial to ensure operative safety and accident avoidance. Our monitoring solutions can additionally aid efficiency in mine operation, producing real-time data to analyse performance and help direct decisions.

Geotechnical monitoring instrumentation is most commonly used within mines, such as piezometers, extensometers, inclinometers and load cells to monitor movement behaviour within these spaces.

Buildings & Bridges

Buildings & Bridges

Buildings & Bridges

Buildings and bridges are subject to a variety of external and internal forces including wind, traffic, heat, earthquakes and people. We believe that monitoring factors such as these is key to fully understand structural behaviour and identify any potential defects. Monitoring structures over time using an array of sensors provides structural health data for a building which can direct development  and analysis.

Monitoring of buildings and bridges is entirely dependent on each individual case, but commonly used instruments measure quantities such as stresses and strains, tilt, deflections, settlement and heave and temperature.

Slopes & Embankments

Slopes & Embankments

Slopes & Embankments

Stability is the fundamental parameter is monitoring of slopes. Protection of people, assets and infrastructure downslope can be provided by monitoring of slopes. Lateral ground movement and soil strength can be quantified and recorded using borehole-based instrumentation such as inclinometers, extensometers and piezometers. For rock faces, instruments like crack-meters can monitor dynamic behaviour. Purpose built embankments and fill stockpiles can also benefit from monitoring of stability.

Typically, stability instrumentation focuses on ground behaviour. Parameters include pore pressure, lateral ground movement, settlement and heave.

Tunnels

Tunnels

Tunnels

Monitoring of tunnels encompasses the strength of the tunnel structure and the ground surrounding it. Ground deformation monitoring in tunnels assists in selection of suitable support mechanisms during excavation and produces an early warning framework to prevent structural damage or ground collapse.  Safety is a critical factor, so selecting the right monitoring instrumentation is vital in accident prevention and project security.

Geotechnical instrumentation is used to monitor ground deformations, typically extensometers, inclinometers and piezometers. Additional instrumentation can be used to measure tunnel profile, such as the Shape Accel Array.
