Confidential Client – Electrical Service Upgrade

Confidential Client – Electrical Service Upgrade

Gayner Engineers served as the Prime Designer for the $10 million infrastructure upgrade project.  The scope includes total replacement of the 5000 Amp, double-ended switchboard at the basement of the first building and components upgrade for another 4,000 amp double-end switchboard at the second building.  Due to the existing conduit stub locations and wiring configuration, extensive field were conducted upfront to define design constraint for early equipment procurement. A complex engineering analysis was conducted to determine temporary power provision during the shutdown based on critical loads of the buildings  The temporary power system configuration was defined upfront for budgeting purpose.  In addition, the new design incorporates distribution modification to allow for manual switching power source for the lab power distribution boards as an effort to provide the flexibility of shutting down one side of the switchboard for maintenance without impacting the operation of important research activities.  With the tight schedule in mind, Gayner worked closely with the project stakeholders, including Building Managers, Building Engineers, Research’s representatives, and EH&S, the general contractor, the electrical contractor, and equipment vendor, with highly focused efforts to meet the critical project milestones. As a result, we were able to finalize the design and issue a PO to the switchgear vendor to get the switchboard in the fabrication queue.  Gayner’s deliverables include Owner Early Switchgear Procurement Package, load monitoring instructions for data logger installation, Concept Design Document, Detailed Design Documents, Specifications, User Requirement Brief, Project Schedule, weekly meeting minutes, and Coordination Study.  Gayner Engineers also performed the coordination study and arc flash study for the project.
