Construction-ready design
A substation package only works if the drawings, equipment ratings, and grounding all line up with how the project will actually be built.

Our process
From project inputs to decision-ready output.
Physical and electrical design for transmission and collector substations — one-lines, general arrangement, grounding, bus sizing, equipment specification, and support through energization.
Basis of design
Voltage, bus configuration, ratings, applicable standards, owner preferences, and site constraints agreed in writing before drawings start.
Preliminary design (30%)
One-line, general arrangement, preliminary equipment list, site layout.
Detailed design (60–90%)
Three-lines, AC/DC schematics, grounding, conduit and cable schedules, foundation loads, bill of materials.
IFC package
Issued-for-construction package; professional sealing provided where required and within the responsible engineer’s jurisdiction.
Construction support
RFI response, submittal review, field changes, and as-builts.
substation design FAQ
Questions before the work begins.
01What voltage levels do you design to?
Voltage level and design boundaries are confirmed during project scoping.
02What’s included at 30%, 60%, and 90%?
30% establishes configuration and footprint. 60% adds three-lines, schematics, grounding, and preliminary schedules. 90% is essentially complete and ready for owner and AHJ review.
03Why does the grounding study matter so much?
Because step and touch potential is a life-safety calculation, and it depends on the actual soil resistivity at your site, the actual available fault current, and the actual protection clearing time.
04Can you design around long-lead equipment?
Yes, and it’s increasingly necessary. Transformer and breaker lead times have driven many projects to design around whatever can be procured rather than what’s ideal.
05Do you stamp drawings?
Professional sealing is provided where required and within the responsible engineer’s jurisdiction.
