In town. A few meetings. Then we fly back.
Owners on the ground in Sioux Falls this November — a short run of site meetings and home assessments. Email to hold a slot.

Who we serve
Built for the facilities going up around Sioux Falls.
Sioux Falls is in the middle of a regional buildout in automated food, agricultural, and power infrastructure — the kind of plants that run on the instrumentation and controls work we specialize in.
Food & ag processing
Automated production lines, packaging, and cold-storage controls.
Power generation & utilities
Instrumentation and electrical support at generation and distribution sites.
Manufacturing & automated production
Controls, panels, and uptime work on automated lines.
Grain, feed & agribusiness
Facility electrical and process controls for grain, feed, and related plants.
How we work
01
Submit
Send an RFQ or project drawings — as much detail as you have.
02
Assess
We schedule a technical site assessment to scope the actual work, not a guess from a floor plan.
03
Propose
A written scope and quote, documented against code and loop standards.
04
Execute
Work performed to NEC/IEEE standards, with as-built schematics and loop documentation on handoff.
Compliance & risk management
Code adherence
NEC, IEEE, OSHA alignment.
Safety protocols
Zero-harm. Site-specific JSA.
Insurance
Comprehensive commercial coverage.
Technical oversight
Industrial operations under oversight of Simon Sumrak — 18+ years power-generation I&C, including Siemens Energy SGT-800 systems at Termoelektrarna Brestanica and hydro-plant assignment support.
From the technical director
Field notes — not brochure copy.
Distilled from Simon Sumrak’s public I&C write-ups. Full posts stay on LinkedIn.
01
SGT-800 flame detector replacement
Critical safety device on a Siemens Energy gas turbine: remove the failed detector, install the new unit, verify flame detection, return the machine to service.

02
4–20 mA / HART, field to SCADA
End-to-end loop check with a process calibrator — six span points, linearity, HART diagnostics (PV/LRV/URV), then confirm the same value on the SCADA screen.

03
Rosemount 0–140 bar verification
Full-range hydraulic check of a pressure transmitter on liquid fossil fuel service, 4–20 mA monitored through to SCADA, error and linearity calculated at each point.

04
In-situ conductivity on demin water
When you cannot pull instruments off a live dosing skid: compare process transmitters against a lab-certified reference probe under real conditions — critical below 1 µS/cm.

Questions we get
- Do you take industrial electrical and I&C work in Sioux Falls?
- Yes. MEK Group handles instrumentation, SCADA/PLC, control panels, and industrial electrical for food & ag, power, manufacturing, and grain facilities in Sioux Falls and the greater Upper Midwest.
- Can we send drawings instead of a site visit first?
- Send the RFQ and whatever drawings you have. We review the package, then schedule a technical site assessment so the quote is based on the plant — not a guess from a floor plan.
- Are you licensed in South Dakota?
- South Dakota contractor / electrical licensing for the local entity is in process and disclosed up front. The technical director has 18+ years of power-generation I&C experience, including Siemens Energy SGT-800 systems.
Send an RFQ
Drawings, a loop list, or a paragraph. We reply in writing with a clear next step — site work is scheduled from that thread, not from a public calendar.
