Although not designed to accumulate and hold water, the PUTP served as a collection point for water that leaked from piping for potable water and steam.
The safety aspect of the design review of the pier was cursory in nature, and the hazard associated with the unprotected PUTP wasn't found during this review.
The fall hazard associated with the PUTP wasn't identified as a construction safety hazard during routine oversight.
Steam leaking from a failed strainer in the dripstation, coupled with leakage from potable-water lines, filled the PUTP with water.
Two different offices assumed the other was responsible, and, as a result, neither office ever checked the PUTP.
