An effective electrical design should consider project-specific needs to ensure the success of your mission.  Beyond a basic MEP design service for a general-purpose application, a custom design for your complex electrical system should consider:

  • Personnel Safety. Considerations to ensure that your maintenance electricians are protected against electrocution and arc flash hazards. The implementation of sensitive ground fault protection, zone selective interlocking, high-speed differential relaying, arc energy reduction switches, fiber optic arc flash sensors, or arc-resistant switchgear should be considered in designs where safety during frequent operation or intervention is paramount.

  • Protection and Control. Solutions of your critical equipment for resilience against both minor and catastrophic faults through the use of adaptive P&C schemes, including dual relaying, differential protection, pilot transfer trip (PTT), direct transfer trip (DTT), line impedance monitoring, negative sequence, and other advanced specialized schemes.

  • Power Reliability. Solutions to ensure minimal impact on your facilities and processes in the event of a utility power interruption. This might include the application of automatic source transfer controls, closed transition restoration, automatic generator starting and synchronization, static UPS systems, or other types of stored energy systems.

  • Inter-Discipline Coordination. Design methodology to properly apply and specify electrical equipment such as motor control centers and variable frequency drives to match the control requirements of your mechanical and industrial process equipment such as pumps, boilers, conveyors, mixers, fans, cranes, propulsion systems, and other types of heavy machinery.

  • Quality Control. Rigorous procedures using a true and tested method of collaboration between our in-house professional engineers and master electricians to assure that your electrical facilities are not subject to variations, deviations, or complications with the AHJ during construction.

  • Operation and Maintenance. Practicality allows your facility staff to use the electrical equipment with relative ease for many years. When construction budgets allow it, our design solutions include provisions for the future expansion of your system.

  • Instrumentation & Control (I&C) and SCADA Integration. Schemes allow remote automation and monitoring of the entire electrical system from a centralized location with data exchange to establish real-time electrical system trending or to validate your overall functionality.
