What action should be taken after trenches for underground piping have been excavated and bedded?

Once trenches for underground piping are excavated and properly bedded, it is essential to carry out an inspection before backfilling. This step is crucial to ensure that the installation meets all safety and operational standards. During the inspection, any potential issues, such as misalignment, inadequate support, or damage to the piping, can be identified and addressed.

Conducting this inspection helps in verifying that the piping is installed correctly, conforms to design specifications, and is protected from potential environmental factors that could compromise its integrity over time. This proactive approach prevents future complications that could arise if the piping were covered without verification, saving both time and resources. The other options, while seemingly important, do not take precedence over ensuring the piping is inspected and ready for safe backfilling.
