Our team provides comprehensive electrical engineering design services for commercial, residential, institutional, industrial, and mixed-use developments. Our team delivers practical, code-compliant, and energy-efficient electrical system designs tailored to each project’s operational and architectural requirements.
Our electrical engineering expertise includes power distribution systems, lighting and lighting controls, emergency and standby power systems, grounding and bonding, equipment connections, electrical coordination, and low-voltage infrastructure coordination. We prepare detailed electrical construction documents including power plans, lighting plans, single-line diagrams, panel schedules, load calculations, riser diagrams, equipment details, and technical specifications.
The 3S MEP+S team is experienced with applicable industry codes and standards including NEC, IBC, IECC, NFPA, and local jurisdictional requirements. We work across a wide range of project types including commercial offices, restaurants, retail spaces, tenant improvements, educational facilities, healthcare facilities, hospitality projects, entertainment venues, multi-family residential developments, high-rise buildings, warehouses, industrial facilities, and data centers.
Our team also have the capabilities to provide photometric analysis, short-circuit and coordination studies, voltage drop calculations, arc flash coordination support, energy code compliance documentation, utility coordination, and construction administration services to support successful project execution.
