A key responsibility of the TV Tech is to produce high quality pre and post TV videos and data and proper lateral cutting
A Pre-installation video is a CCTV (Closed Caption TV) inspection done prior to pipe and lateral rehabilitation.
A Post-installation video is an inspection performed following pipe rehabilitation and lateral reinstatement / rehabilitation.
In both, high quality video is essential! Should any questions rise, our videos are evidence that we have done our job.
2.3 Video examples
Without high quality video we run the risk of
Wasting valuable time and resources
Alienating Customers and
Causing mistakes in the reinstatement process
Not getting paid
2.4 client video
Check out what can happen as a result of low quality video.
This video was provided to the customer. Due to the low quality, the customer did not accept the video because they could not see the entire pipe. We had to re-TV the line costing us thousands of dollars. This could have easily been identified during the review process in the field.
To avoid these types of problems and increase our efficiency and bottom line, we need to standardize our process from truck to truck, job to job, and TV Tech to TV Tech.
3.2 Equipment Activity
To do your job properly, you need to understand, operate and maintain the TV Truck and job-site equipment.
We will go into more detail on specific equipment needed to produce a high quality pre and post TV inspection in later modules, but for now, click on each item for a brief description.
Here’s a very brief overview of the TV Tech’s activities. We will go into more detail on each of these in later modules.
5.3 Inspecting the Line
To TV the line, with the help of crew members, insert the camera into the pipe and position it where the manhole meets the pipe.
It is a best practice to clean the line prior to pre and post inspection. This impacts the quality of your video.
5.4 Inspection software
Connect your computer to the internet and remain connected throughout the entire job. Open the inspection software, enter the initial inspection details, and hit record. You can never capture too much information. “Record what you can see” is a good rule of thumb.
5.5 Flagging Incidents
While moving through the line, flag laterals and any defects that needs to be noted.
At the end of the inspection, stop recording. Review the video and data for accuracy and quality. If there are any problems take the time now to re TV the line.
5.7 Generate report
Once the video and data meet SAK standards, generate your report and upload the video to the SAK servers.
5.8 Rehab Begins
The pipe or lateral rehabilitation job can begin. If laterals exist, the laterals will need to be reinstated.
After all reinstatements, and prior to post-TV inspection, the line should be cleaned again to remove any accumulated debris from rehabilitation. Cleaning is a key factor in producing a high quality video.
5.10 Upload the Videos
Once the job is complete, you need to make sure to allow enough time to upload the videos. Coordinate with your superintendent or foreman to ensure there’s enough time without rushing.
