Electrical power system design, sealed by a licensed PE.
Service entrances, distribution equipment, feeders, and transformers sized for the real connected load and coordinated with the rest of the building before it reaches the field.
Power distribution is the backbone every other electrical system hangs off. Get the service size, feeder routing, or equipment ratings wrong and the problem does not surface on paper, it surfaces during rough-in when the gear will not fit, the utility will not energize, or the panel schedule no longer matches what was installed.
We design the full path from the utility point of connection through service entrance equipment, switchgear and switchboards, distribution panels, transformers, and branch panelboards. Load calculations are built from the actual equipment schedules rather than assumed watts-per-square-foot, so the service is sized for what the building will really draw, with documented spare capacity where the owner expects to grow.
Every drawing set is produced in Revit and coordinated against the architectural and mechanical models as it develops, so conflicts are resolved in the model instead of in the field. The finished set is sealed by a professional engineer licensed in the project's state.
What it covers
- Service and distribution design
- Panelboards, switchboards, and switchgear
- Transformers and feeder sizing
- Load calculations and demand factors
- Grounding and bonding
- Panel schedules and one-line diagrams
Sealed drawing set
One-line diagrams, power plans, panel schedules, and details, stamped by a PE licensed in your project's state.
Load calculations
Documented calculations behind the service size, including demand factors and the spare capacity carried.
Equipment schedules
Distribution equipment identified with ratings, so procurement and submittals do not stall waiting on clarification.
Coordinated model
A Revit model coordinated against the other trades, delivered alongside the drawings.

What is included in an electrical power system design?
A power system design covers the electrical path from the utility connection through service entrance equipment, distribution, transformers, and branch panels. Vertical Design Services delivers one-line diagrams, power plans, panel schedules, load calculations, and equipment ratings, sealed by a licensed professional engineer.
How do you size an electrical service?
The service is sized from the actual connected load, built up from the real equipment schedules for the project rather than a generic watts-per-square-foot assumption, then adjusted using the demand factors the code allows. We document the calculation and carry whatever spare capacity the owner wants for future growth.
Can you design power systems for projects outside Illinois?
Yes. Vertical Design Services holds active PE licensure in more than 20 states, so the same team can engineer and seal a power system design wherever the project is, without you finding a new firm each time a job crosses a state line.
Do you coordinate the electrical design with the other trades?
Yes. Designs are produced in Revit and coordinated against the architectural, structural, and mechanical models as they develop, so equipment clearances and routing conflicts are resolved in the model rather than discovered during installation.
