A Substation Design Error Doesn't Surface in Review. It Surfaces at Commissioning, When the Outage Window Is Already Open.
Substation mistakes are the most expensive kind in this business. An outage window takes months to schedule. A respecified transformer or switchgear set moves an energization date by quarters in today's supply market. An interconnection package that fails utility review can cost a developer their queue position, and the project with it.
That's why this reader checks references first and marketing copy never. We build to match. Engineer-supervised QA/QC on every package, daily fluency in SRP and APS standards and review processes, and a scope you can verify line by line before you commit.
We're a Service Disabled Veteran-Owned Small Business based in Phoenix, working inside the same utility standards this work answers to.
— How We Work
What Makes Working With ARUSI Different
01
Already inside your standards and review world.
We work daily in SRP and APS standards, work-order conventions, and review processes, the same utilities this work answers to. A vendor already inside your world carries less onboarding risk on substation scope.
02
Program discipline at utility scale.
QA/QC gates, weekly hours tracking against estimates, and documented change control. Substation buyers weight process maturity heavily, and this is process built on real program volume.
03
A scope you can verify.
We name what we self-perform and what we don't, in writing. Physical, civil/structural, and drawing scope is stated separately from protection and control, system studies, and commissioning. You'll never find out at commissioning that a scope line was assumed.
04
Substation-specific depth.
Engineering, this card is the one that converts this reader and it is currently empty. Supply: which staff carry substation design backgrounds, what physical/civil/structural scope has been delivered, and on which stations. Without it, this card should be cut rather than filled with generic language.
— What We Do
Substation Design Support
Substation design support within utility programs, built to the owner's standards.
VERIFY scope
Civil / Structural Packages
Foundations, structures, and grading packages for substation sites, coordinated with the station physical design.
AutoCAD + MicroStation
Drawing Production
Station drawing packages produced under engineer-supervised QA/QC in AutoCAD and MicroStation.
Outage-Driven
Brownfield Modification Packages
Modification and upgrade packages sized to outage windows, governed by existing-record quality and the client's outage calendar.
— The Engagement
How a Typical ARUSI Engagement Works
No ambiguity about how the work starts or how it moves. Here's what to expect.
1
Contact and scoping
You share the station scope (new, expansion, or upgrade), one-line basis, utility standards, outage constraints, and interconnection milestones. ARUSI assesses fit and names what it will and won't self-perform.
2
Proposal
Defined deliverables across physical, civil/structural, and drawing scope, an hour estimate by discipline, and a schedule tied to your outage and procurement calendar. Exclusions explicit, especially protection and control and studies scope.
3
Kickoff
Standards, existing-station records, and site data transferred. Review gates and submittal calendar aligned to the utility's process.
4
Design production
Station physical design, bus and equipment arrangements, civil/structural packages, and drawings produced under engineer-supervised QA/QC to the owner's standards.
5
Utility review and revision
Comments resolved on rapid turnaround, and changes coordinated against equipment procurement so drawings and ordered equipment never diverge.
6
IFC and construction support
Issued-for-construction packages, field question response, and as-builts through energization.

Frequently asked questions
ARUSI provides substation design support within utility programs: physical design support, civil and structural packages, and drawing production to the owner's standards, under engineer-supervised QA/QC
Protection and control engineering and system studies such as grounding, arc-flash, and coordination are scoped separately. ARUSI names them on a project only where the capability is staffed and confirmed.
ARUSI works daily in SRP and APS utility standards and produces to the owner's standards on each project.
ARUSI's primary NAICS codes are 541330 (Engineering Services), 541340 (Drafting Services), and 541370 (Surveying and Mapping Services). It also works under 237130 (Power and Communication Line and Related Structures Construction).
ARUSI is headquartered in Phoenix, Arizona, at 4720 E Cotton Gin Loop #140, Phoenix, AZ 85040. It has served clients across Arizona and the Southwest since 1987.
Yes. ARUSI's SDVOSB status and enterprise certifications let national firms meet set-aside and small-business goals while keeping local engineering depth on the team. ARUSI bids as both prime and subcontractor.
