Engineering Design

Electrical system design for commercial and industrial projects — new construction, renovations, tenant build-outs, and design-build work. Code-compliant designs that work in the field, not just on paper.

Electrical Design Services

Zech Engineering provides electrical system design for commercial and industrial projects. Whether it's a ground-up build, a renovation, a tenant improvement, or a design-build collaboration, we deliver practical, code-compliant designs that constructors can build from and inspectors will approve.

Power Distribution Design

Complete electrical power system layouts and infrastructure design, from the service entrance through branch circuits. We size transformers, switchgear, panelboards, feeders, and branch circuits per NEC requirements, and coordinate with the serving utility on service design.

Lighting Design

Interior and exterior illumination design that meets IES recommendations, energy code requirements (IECC / ASHRAE 90.1), and project aesthetic goals. Includes lighting layouts, fixture schedules, circuiting, and control systems.

Panel Schedules & One-Line Diagrams

Detailed panel schedules, one-line diagrams, and electrical riser diagrams that clearly communicate the design to contractors and serve as the basis for permitting and construction.

Service Upgrades

Engineering evaluation and design for electrical service upgrades, increasing capacity for facility expansions, equipment additions, or EV charging infrastructure. Includes utility coordination, equipment specification, and arc flash impact assessment.

Tenant Build-Outs

Electrical design for commercial tenant improvements, including office spaces, retail, restaurants, and medical offices. We work within existing building infrastructure to deliver cost-effective designs that meet the tenant's operational needs and local code requirements.

Our Approach

Every design starts with understanding the project's goals, constraints, and budget. We produce construction-ready documents, not theoretical exercises. Our designs account for real-world conditions: equipment availability, contractor means and methods, and local code amendments. We also coordinate with power systems analysis to verify that new designs integrate safely with existing infrastructure.

As a licensed PE, Nick Zech brings both engineering rigor and field experience to every project. The result is designs that don't generate RFIs or change orders due to buildability issues.
