CONFIDENTIAL CLIENT (CONT.)

Throughout the commissioning process, the construction team and facilities engineering group resolved major system troubleshooting needs and provided the owner with the necessary validation steps to begin move-in and owner training on time to be ready for production.

Resilience And Troubleshooting

During the commissioning process, a sump pump exhibited inadequate performance during a quick system shut off for the cooling tower system. We identified emergency run off for the cooling tower basin overflow and normal water flow from the sewage ejector was causing an overflow into the production facility. After performing integrated testing of system shutdown and sewage ejector float testing, the contractors were able to add guides to the float assembly based on the observed conditions. This adjustment resolved the overflow issue and helped ensure the pump engages earlier to remove water from area.

Additionally, HEAPY identified a major issue during emergency system power testing of an electrical load shed and substation building program. The electrical sequencing missed one of the sub stations and upon investigation, the on site team identified a field wiring issue as the culprit. Further, an ungrounded terminal was identified during this investigation. Both issues were corrected prior to a final witness testing when the substation began providing large amounts of power to the facility at increased voltages and amperages. Because our team discovered and corrected these issues prior to the programs going online, downtime and additional problems for the plant were mitigated, saving the client maintenance staff expenses and mollifying operational difficulties.

Collaboration

During power system witness testing, the rotations of two sub stations were found to have different rotations. Discussions with electrical contractors, design engineers and facility engineers determined both substations should be in the same rotation to avoid any future potential errors. The power systems contractors revised the programming and adjusted based on the team’s recommendation during the next power shutdown.
