A participant describes anchors installed in a concrete vault to support a cable-pulling pulley. She acknowledges that engineers have tested hardware and load calculations, while expressing a personal preference for mechanically secured anchors. She suspects that pulling force began to dislodge a bolt, but explicitly says she has not seen the installation and does not know that this happened. Work is reported to have stopped for reassessment of the pulling method. The example shows the importance of separating firsthand evidence, personal confidence in equipment, and an unresolved explanation of a stopped job.

An engineering anecdote distinguishes suspicion from a confirmed failure
The account preserves the difference between a suspected anchor problem and an inspected, established cause.
