Deep Excavation Monitoring

Compliance focused monitoring for high risk excavation projects

Deep excavations present a complex geotechnical compliance challenge. From ground movement to wall defamation, even the slightest variation can escalate into a major risk if left unmonitored.

Monitel delivers comprehensive, site specific deep excavation monitoring systems to sites across Western Australia. Using market leading tiltmeter technology, they are designed to provide real time insights into surface and structural behaviour – ideal for meeting compliance requirements and making informed decisions through every stage of excavation.

Supporting safe excavation through accurate, real time data

Effective monitoring is critical in understanding how excavation activities are affecting site stability. Our monitoring systems capture data across the following risk indicators:

• Lateral wall movement
• Settlement
• Pore water pressure
• Structural response of adjacent assets

Our team integrates multiple sensor types into a singular monitoring system to provide a comprehensive picture of site risk. This enables the early detection of anomalies and proactive interventions.

Real time data is collected in a cloud based reporting software, offering site managers continuous access to geotechnical conditions. This enables confident decision making that can address warnings before they develop into catastrophic failures.

End to end monitoring solutions tailored to your project

Every excavation is different. Soil conditions, depth, surrounding infrastructure and so much else influence the design of an effective monitoring program.
Our team take a tailored approach to deep excavation monitoring, working closely with your engineers and site managers to design a system aligned with your methodology and regulatory obligations. Our end to end service includes:

System design and instrumentation selection

Our team assess site specific conditions to select the most appropriate tiltmeter technology. Our services include:

Installation and commissioning

Monitel technicians install and configure instrumentation according to best practices, including proper placement, sealing and calibration. Sensors are also integrated with new or existing data logging systems.

Automated monitoring and reporting

Your sensors provide continuous, real time data on a cloud based platform. Our dashboards provide visualisation and threshold alert capabilities.

Ongoing support and maintenance

Our team will assist you with ongoing monitoring, data validation and system maintenance to ensure long term performance. We can also assist you with regulatory reporting and compliance management.

Built for unforgiving conditions

Deep excavation is often conducted in WA’s regions, where environments are harsh and demanding. Equipment must be robust and perform reliably against moisture and vibration.

As part of our system design, we account for your site’s climatic realities and assemble sensors to withstand tough conditions. This ensures consistent performance over the life of your project and means you can rely on your monitoring system when you need it most.

Our Sensors

Monitel designs deep excavation monitoring systems using a combination of geotechnical and structural technologies. Our team commonly deploys:

• Inclinometers and tiltmeter technologies (to monitor lateral surface and wall movement)
• Piezometers (to measure pore and groundwater behaviour)
• Load and strain instrumentation (to assess structural performance)

A blend of different technologies provides a more holistic picture of site risk. Piezometers, for example, can identify water pressure changes that affect stability. At the same time, tiltmeter technology can monitor how surface movement is working in tandem.

Monitel is proud to be partnered with Osprey Measurement, Wisen and Viotel to provide our clients with market leading sensor technology. Nonetheless, we believe in a product and brand agnostic approach and will always select the sensor best suited to your site’s risk profile. Our bottom line does not factor in to our recommendations.
