A recent shared learning reminds us of the importance of exercising caution and skepticism, even when a seemingly knowledgeable person gives information regarding a job. During a pre-dig meeting at a private residence, after utility locates, the property owner explained that he had personally replaced his sewer line at approximately 6’ bgs.  Being a former city inspector, the team took his word as good, and cautiously opted to excavate with a mini-excavator. However, the line was actually encountered at approximately 3’ bgs, with no sand or pea gravel backfill to indicate its presence.  The sewer line was also located extremely close to a water well – not within proper municipal utility installation distances.  A stop work was called, and the issue was quickly resolved.

In reflecting on the incident, information obtained from third parties should be carefully considered.  It is required of us to consult with third parties (when available), but you can’t assume the information you are receiving is without error, or that the initial utility installation work was performed correctly. You always use third-party information with caution. Expect the unexpected.
