Smart Data Acquisition Technology (SDAT)

HIgh-tech Data Acquisition

The key to SIAMA’s Smart Data Acquisition Technology lies within the capability of its UAVs (Unmanned Aerial Vehicles) and UGVs (Unmanned Ground Vehicles), which are remotely piloted to capture a detailed and accurate digital image data of all exposed surfaces.

Unmanned Aerial Vehicles (UAVs)

The SIAMA UAV system employs a purpose-developed scanning and local positioning system to overcome navigation challenges associated with positioning the UAV in relation to the bridge or tall structure.


How it works

1 The UAV’s guidance system incorporates a high accuracy Internal Measurement Unit (IMU) and precision laser measurements to achieve and maintain a location accuracy of better than 10mm underneath a bridge deck without a GPS signal.
2 The system’s local positioning data processing capability and high resolution digital camera deliver mirror-image scans to provide asset owners with the unique opportunity to “overlay” digital image data and build a progressive profile of each individual structural component.
3 Significantly, SIAMA’s UAV system allows the entire surface of the bridge or structure to be accurately recorded and analysed while maintaining a safe and secure work environment for staff and the general public.

Features and Benefits (for both UAV & UGV)

  • SIAMA’s objective inspection techniques eliminate the inconsistencies associated with subjective manual visual inspections, which rely on human identification, assessment and reporting of condition and defects;
  • Ideal budgeting and planning tool as scan data can be ‘overlayed’ to monitor defects and build a progressive data profile of each individual structural component;
  • SIAMA’s asset inspection and data collection system maintains a safe and secure work environment for staff and the general public;
  • All inspection, data collection, assessment and analysis activities are conducted by qualified engineers, inspectors and operators; and
  • Full bridge access can be maintained during inspection and data collection activities, removing or minimising the need for traffic management services.
  • Alternately, where required SIAMA’s expert technicians can also conduct all levels of condition assessment condition assessment inspection activities utilising traditional visual / manual asset inspection methods.

Unmanned Ground Vehicles (UGVs)

SIAMA’s remote controlled mini UGV is capable of conducting autonomous culvert inspections
in confined spaces as low as 1.2 metres in height.


How it works

1 The UGV utilises the same state-of-the-art scanning and positioning system employed by SIAMA’s UAV to navigate and capture 360-degree surface imagery of the entire length of the culvert.
2 These images are then paired with distance measurements captured by the UGVs laser sensors to identify and record the exact position of a specific defect.
3 SIAMA’s UGV system also allows the entire surface of the culvert to be accurately recorded and analysed while maintaining a safe and secure work environment for staff, by eliminating the issues associated with operating in confined spaces.

Features and Benefits (for both UAV & UGV)

  • SIAMA’s objective inspection techniques eliminate the inconsistencies associated with subjective manual visual inspections, which rely on human identification, assessment and reporting of condition and defects;
  • Ideal budgeting and planning tool as scan data can be ‘overlayed’ to monitor defects and build a progressive data profile of each individual structural component;
  • SIAMA’s asset inspection and data collection system maintains a safe and secure work environment for staff and the general public;
  • All inspection, data collection, assessment and analysis activities are conducted by qualified engineers, inspectors and operators; and
  • Full bridge access can be maintained during inspection and data collection activities, removing or minimising the need for traffic management services.
  • Alternately, where required SIAMA’s expert technicians can also conduct all levels of condition assessment condition assessment inspection activities utilising traditional visual / manual asset inspection methods.

Mini Crane and Rail System

High-Tech Data Acquisition When Flying Isn’t An Option

As versatile as SIAMA’s UAVs are, there are some situations where using a UAV isn’t a viable option,
and for these inspections, SIAMA’s Mini Crane and Rail System is used to perform under-bridge
inspection and data collection activities.


How it works

1 The system also incorporates a post-tensioning device to ensure that the rail is supported on a level plane between the two mini-cranes.
2 The Mini Crane and Rail System also utlises SIAMA’s proprietary data-point technology to ensure all measurements point consistent between asset condition assessments.
3 As with SIAMA’s UAV inspection activities, the Mini Crane and Rail System does not require the bridge to be closed during inspection activities, beyond the closure of pedestrian access on one side of the bridge.

Features and benefits

  • The Mini Crane and Rail System provides a safe and secure work environment for staff by eliminating the need for scaffolding, ladders and harnesses when conducting under-bridge inspections in difficult locations;
  • Vehicular access and modified pedestrian access can be maintained during inspection and data collection activities, removing or minimising the need for traffic management services; and
  • The Mini Crane and Rail System is an efficient, accurate and cost effective alternative to current with visual-based manual inspection techniques.
