What CCTV inspection records
A crawler camera travels through an accessible pipe while the operator records video and observations. Depending on access, flow, pipe condition and project scope, the deliverables may include pipe identification, inspection direction, footage distance, observed defects, associated codes, still images and video files.
When contractors request it
Common scenarios include municipal condition assessments, construction handover, pre-construction condition documentation, investigation of suspected defects and periodic asset-management inspections. Confirm the governing municipality’s current specification before booking; some require specific versions of coding standards or data-file formats.
How to prepare
Provide available utility plans, pipe sizes and materials, manhole identifiers, access arrangements, traffic-control requirements and any existing inspection records. Ask whether flushing must take place before video work and how reports will be delivered.
What to request in a quotation
Define the pipe segments, approximate lengths, expected field conditions, reporting standard, deliverable format, schedule and whether flushing, traffic management or confined-space controls are in scope. These details help avoid unexpected work.
