Landmark engineering across defense, entertainment, aerospace, pharmaceutical, and infrastructure sectors — nationwide.
Replaced 1960s Ward Leonard motor-generator sets with modern ABB VFDs and redundant PLCs. Phased six-month changeover kept one tram running at all times. Recognized with the 2018 Notable Engineering Achievement Award.
Replaced a 16,000 HP wound-rotor motor with an 18,700 HP, 6,600 V ABB ACS-5000 MV VFD. Engineered 36-pulse phase-shifting transformers, cooling towers, MV switchgear, and a precision 120,000 lb drive rigging operation. 2009 Engineering Achievement Award.
Six-megawatt N+1 emergency power system for a Joint Commission–accredited VA hospital: three 2 MW, 13.2 kV diesel generators, 60,000-gallon fuel tanks, 51 ATSs, and redundant PLC controls. Facility was never dark >1 hour during phased construction. 2015 Notable Award.
Engineering, design, PLC programming, and commissioning for an indoor skydiving wind tunnel. A novel horizontal motor and gearbox configuration (patents US 10,765,958 B2 and US 11,731,057 B2) replaced the traditional nacelle design. 2019 Notable Engineering Achievement Award.
Power system studies and arc flash assessments for the MV and LV distribution systems at the Philadelphia Convention Center Exhibit Hall and Train Shed Buildings. SKM PTW model, TCC coordination, incident energy calculations, and arc flash labeling.
Comprehensive electrical power audits and arc flash hazard analyses across eleven CertainTeed roofing manufacturing plants. IEEE 1584-2018 methodology, SKM PTW modeling, NFPA 70E arc flash labels, and device resetting recommendations to reduce incident energy exposure.
Full short circuit, TCC coordination, and NFPA 70E arc flash assessment for a pharmaceutical plant operating 7 MVA of emergency generators and 960 kVA of UPS systems. Selective coordination focus, VFD harmonic-aware modeling, PPE category determinations, and economic payback analysis.
Modernization of twenty-two (22) Unit Substations in the Exhibit Hall and Train Shed, 13.2 KV protective relay replacement, and thirteen (13) Automatic Transfer Switch replacements — with arc flash levels reduced to ~12 cal/cm² through transformer differential relays and a Power Monitoring and Advisory System. 2025 Outstanding Engineering Achievement Award.
