Inspection of Near Surface Structures eLearning
This course provides an understanding of the design provisions within the permanent works to facilitate the inspection of structures, e.g. where you would normally use CCTV access covers and personnel access to below ground structures via ladders we will use drone technology. It also provides training on where to find the coverage reports and an understanding of the drones and lighting technologies that are available to support the inspections.
Description
The course will cover:
-
Provisions within the permanent works to enable inspection of structures:
-
CCTV access covers;
-
Personnel access to below ground structures (Ladders);
-
Limitations of CCTV provision, typical extent of ‘in person’ inspections required;
-
Example CCTV and lighting technologies;
-
Where to find more information:
-
CCTV coverage reports;
-
10-year inspection plan.
- Provisions to enable drone inspection
-
Limitations and constraints of drone inspections
-
Description of drone technology employed on Tideway
-
Locating the relevant O&M Manual for using drones for the assets to be inspected, on the O&M Portal.
-
This course will cover the generic/standardised provisions that are common to all worksites. Worksite-specific provisions and limitations will be contained in the 10-year inspection plan. - Near surface structures includes all below ground structures up to the point that the connection culvert joins the drop shaft. Inspection of the shafts and tunnel is covered in a separate course. Tunnel and Shaft Inspections STIC-003
Outcomes
On completion of the training, Delegates are expected to understand:
- How to inspect the near-surface structures using the provisions made in the permanent works to minimise manned access;
- Where to find the CCTV coverage reports and thereby establish the extent of ‘in person’ inspections required for each site;
- The CCTV and drone technology available on the market
Competency/Skills Requirements
Before attending the training session, Delegates are expected to complete:
- LTT System Overview.
Before attending the training, Delegates are also expected to have:
- Experience in managing/carrying out inspection of reinforced concrete structures.
