Culvert Dilapidation Inspection





Visual inspection and reporting of culvert condition and structural integrity to support hydraulic performance assessment.

Culvert Inspection

Diospatial’s culvert inspection solution provides engineers with a reliable condition assessment to better understand the hydraulic performance of culverts and geotechnical impact on the surrounding area.

Utilising a pipe crawler, high resolution imagery and video is captured throughout the length of the culverts and pipe networks. The angle throughout the pipe is measured to understand the waterflow and therefore hydraulic performance.

Once all on-site data is captured, the data is then assessed remotely. The pipe and culvert inspection is completed using the imagery and video captured. Defects, debris and any other intrusions like roots or foreign objects are observed and recorded.

Changes in the angle of the pipe that are of significance are identified and recorded as part of the assessment.

Based on the observations, an assessment of the hydraulic functionality of the pipes is made and a report is compiled for delivery to the client.

DATA DELIVERABLES

With every inspection, Diospatial provides a report that simply and clearly explains the methodology, summary of findings, a condition rating and all imagery and videos captured.

A detailed summary of the culvert inspection findings is provided. For each defect observed, the location, observation summary, time, photo reference and classification grade is listed. Photos of the specific defects is included in the report to highlight the points of concern to engineers and other project stakeholders.

The full set of image and video files are made available for download with the inspection report for reference as needed.

When relevant, other spatial data can be captured to show the location and condition of the culverts. This may include a detail and level survey or digital twin to map the location and visualise the condition of the culverts. These can be delivered in high resolution PDFs or via a web-based 3D GIS platform, Pointerra, that is easy to access by all project stakeholders.

The report can be easily used and understood by other project stakeholders and provides a robust record of the methodology, assessment, and findings.

The culvert inspection report clearly identifies defects and compromised points within a pipe, saving time for consulting engineers.

As with all survey and engineering, quality control is critical. All data captured is checked on site to ensure images are of a high quality and accurately geolocated. The data captured is organised by culvert with accurate location identification.

Location and angle measurements are calibrated and recorded in the report to ensure the accuracy of defects that are reported.

A legend with the grading system for the condition assessment classification is summarised in the report to ensure the grading rating is controlled and consistent throughout multiple inspections.

The deliverables include a report that simply and clearly explains the quality control and validation process and any limitations. The report can be easily used and understood by project stakeholders and provides a robust record of the acquisition, processing, and delivery of the data.

The culvert inspection solution provides engineers with the identification and assessment of defects, allowing engineers to focus their time on the planning and design of remediation works.

Diospatial’s culvert inspection solution is a fit-for-purpose solution that is designed to provide our clients with a complete identification and assessment solution for understanding the condition of culverts. By providing better data, we reduce uncertainty so that our clients can make more informed decisions.

When combined with other reality capture technologies, an integrated solution provides engineers with a complete picture of the surrounding landscape and other impacting conditions. This can include, but is not limited to:

Culvert Inspection and Dilapidation Reporting
Culvert inspections are completed with a pipe crawler, equipped with a light, high resolution camera and angle sensor.
Culvert inspection report
The inspection report includes observations of defects and the like, the location, time, photo reference and classification grade, allowing engineers and project stakeholders to focus on the areas of concern.
Culvert Inspection
Images and measurement are taken on site, organized by each culvert, and checked on-site to ensure a robust data capture.
survey and laser scanning for change detection
An integrated spatial data solution can provide greater context as to the cause and impact of defects in culverts.
