What We Do

Engineering
Services

PE-stamped electrical, controls, and embedded systems engineering — from power infrastructure to custom field automation. Two tracks, one engineer, one stamp.

01

Infrastructure & Power Systems

Medium voltage system design for pump stations, water infrastructure, and remote facilities. Utility interconnections, transformer sizing, and construction-phase engineering support.

Medium Voltage Pump Stations Utility Interconnect Construction Support
MV System Design
Medium voltage electrical design for pump stations, well facilities, and remote infrastructure. Voltage class selection through equipment sizing.
Utility Interconnections
Utility service design and coordination including padmount transformer sizing, metering, and utility interface requirements.
Transformer & Switchgear Sizing
Transformer sizing calculations per IEEE Std 141, short circuit analysis, and switchgear interrupting capacity verification.
Voltage Drop Analysis
Feeder and motor circuit voltage drop calculations to verify acceptable starting and running conditions under full load.
Brownfield Modifications
Electrical evaluation and modification design for existing facilities. Field reconnaissance, existing system assessment, and upgrade documentation.
Construction-Phase Support
RFI response, submittal review, and field coordination through construction. PE available through startup and commissioning.
02

Electrical System Design

Power distribution engineering from service entrance to load. LV and medium voltage motor circuits, load calculations, and permit-ready drawing packages built to NEC.

NEC Compliance LV & MV Permit-Ready Motor Circuits
Power Distribution & One-Lines
Single-line diagrams from utility service through distribution to load. Clear, permit-ready, and coordinated with equipment submittals.
Motor Circuit Design
NEC Article 430 motor circuit engineering — conductor sizing, OCPD, controller, and overload for LV and medium voltage motors.
Load Calculations
Service entrance and feeder load calculations per NEC Article 220. Equipment sizing and demand factor analysis.
Equipment Selection
Switchgear, MCC, transformer, and disconnect specification with manufacturer coordination and submittal review.
Grounding & Bonding
Grounding electrode systems, equipment bonding, and NEC Article 250 compliance for industrial and infrastructure facilities.
Permit Drawing Packages
Complete PE-stamped drawing sets formatted for AHJ submittal. Coordinated with civil and mechanical disciplines as required.
03

Controls & Panel Engineering

Complete panel packages built for the shop floor. From PLC documentation through wiring schedules and BOM — manufacturable, submittal-ready, and PE-stamped.

UL 508A PLC / HMI Submittal Support As-Built Docs
Control Panel Design
Full panel design packages for UL 508A fabrication. Enclosure layout, component selection, wire sizing, and termination schedules.
PLC & HMI Documentation
I/O lists, network architecture, and system documentation to support PLC and HMI integration and commissioning.
Wiring Schedules & BOM
Complete wiring schedules and bill of materials formatted for direct use by the fabrication team. No interpretation required.
Submittal & Shop Drawing Support
PE-stamped submittal packages and shop drawing review support through the approval process and into construction.
Field Modifications & As-Builts
Documentation of field changes and as-built drawing packages for existing systems requiring modification or record updates.
RTU & Remote I/O Systems
Remote terminal unit design and documentation for SCADA-connected infrastructure including pump stations and utility facilities.

Embedded Systems & Field Automation

Most engineering firms can design the system. Most developers can write the code. SpetroTech does both — and stamps the drawings.

Purpose-built field monitoring devices, remote automation systems, and cloud-connected instrumentation — engineered from the embedded layer through the power distribution layer by the same PE. For clients who have a vision and need an engineer who can execute it end to end.

Embedded Systems Field Devices Remote Automation Cloud I&C PE-Stamped
Field Monitoring Devices
Purpose-built embedded monitoring hardware for field conditions — pressure, flow, level, temperature, and status — with onboard processing and communication.
Remote Automation Systems
End-to-end remote automation for operations without infrastructure. Autonomous control logic, communication backbone, and PE-stamped power supply design.
Cloud-Connected I&C
Instrumentation and control systems with cloud connectivity for remote monitoring, data logging, alarming, and dashboard visibility from anywhere.
Embedded Control Development
Custom embedded firmware and control logic development for industrial applications. Microcontroller selection, peripheral integration, and field validation.
SCADA Integration
Integration of field devices and automation systems into existing SCADA architectures. Protocol selection, communication design, and HMI coordination.
Product Development Support
Engineering support for clients developing custom automation products — from concept through prototype, with PE-stamped documentation for commercialization.

Product Development Clients
Who We Work With
Industrial Operators
Small and mid-size operations that need engineering capability without a full-time internal team — from one-off design problems to ongoing project support across controls, power, and automation.
Infrastructure Owners
Municipalities, utilities, and facility owners that need independent electrical engineering for upgrade design, new construction, or construction-phase PE support.
Civil & MEA Firms
Engineering firms that bring SpetroTech in as their electrical subconsultant for pump stations, water infrastructure, and municipal utilities — peer-level collaboration, not vendor management.
Systems Integrators
Integrators with complex controls scope who need PE-stamped documentation, I/O design, or embedded systems engineering to complete their solution and meet submittal requirements.
Contractors & EPC Firms
Contractors bringing controls or MV scope to a project who need a licensed PE as their engineering partner — responsive turnaround aligned to active project schedules.
Fabrication Teams
Panel fabrication shops with complex scope who need engineering documentation their team can build from directly — wiring schedules, BOM, and layout packages with no interpretation required.
