PE-led industrial engineering · Carolinas & Southeast
Engineering for manufacturers who can't stop the line
Smith Industrial Engineering and Consulting PLLC (SIEC) helps manufacturers in the Carolinas and Southeast cut hidden plant costs and raise output. We measure first, then deliver work in live production windows. Typical waste or throughput opportunity is 10-25% when the facility baseline supports it.

Live plant work
Capture, utilities, and capital packages under production constraints
Services
What we do
Industrial ventilation · Industrial energy audits · Capital delivery · Simulation and design validation · Digital transformation
Industrial ventilation
Source capture, duct systems, and room balance fixed before anyone upsizes a fan.
02Industrial energy audits
Utility spend mapped to process and exhaust loads, with whole-facility energy modeling to predict savings before spend.
03Capital delivery
Owner's-engineer lead on line work, phased into production windows and off-shift tie-ins.
04Simulation and design validation
Airflow, thermal and energy simulation when it changes the decision, so options are tested before purchase orders.
05Digital Transformation for Manufacturers
Engineering-led digital twins. Connect plant data pipelines and analytics to plant decisions.
Also available
EPAct 179D certification
PE documentation when records support eligibility. Your CPA files the return.
Why manufacturers choose SIEC
-
01
Senior-led: the PE who scopes your project leads it start to finish
Stephen M. Smith, PE scopes, engineers, and stands behind every package.
-
02
Success defined before tools are bought.
We agree acceptance criteria up front and verify results before handoff, so performance is checked, not hoped for.
-
03
Your production keeps running.
Pilots, phased packages, and off-shift tie-ins, with the halt definition agreed before mobilization.
-
04
Test options in simulation before you spend, including digital twins
Options are compared before purchase orders, across ventilation, capital, and digital work.
-
05
One firm, five disciplines.
Ventilation, energy audits, capital delivery, simulation, and digital transformation under one PE, so the fix is not limited to one trade's toolkit.
-
06
Teaming-friendly: we work alongside your contractors and integrators, not against them
Your contractors and integrators stay in the work.
Method
Evidence before capital. Implementation under production constraints.
-
Diagnose
Agree success criteria. Map utility, ventilation, process, and schedule constraints your plant actually runs under.
-
Model and validate
Use field data and airflow, thermal and energy simulation only when they change the decision. Compare options on a shared measurement basis.
-
Implement live
Phased packages, off-shift tie-ins, and verification against acceptance criteria before handoff.
Work
Measured results from live plants
Client names withheld where required. Constraint, method, and verification are not.
Submicron exhaust control for an NC plastics plant
Source capture and separation upgrades that cut mass loading and fan energy while production continued. Used simulation where layout options changed capital.
Utility waste mapping for a Carolinas manufacturer
Facility audit tied about 22% of utility spend to constant-volume exhaust and delivered verified reduction in one operating season.
$5M process line extension without stopping production
Owner's-engineer delivery of a multi-million-dollar line extension with zero unplanned production halts under the agreed definition.
Engineering-led digital thread for a global manufacturer
Plant data pipelines and analytics with engineering acceptance tests after a pilot-first rollout.
Fit
Built for the people who own cost, uptime, and worker safety
Good fit
- Owners, plant/ops leaders, facilities, EHS, engineering
- Carolinas & Southeast manufacturers with uptime rules
- Buyers who want options and measurement, not theater
Not a fit
- Guaranteed savings without a measurement basis
- Tax-only shopping with no facility engineering need
- Unlimited open scope without acceptance criteria

FAQ
Common questions from plant teams
- Who should engage SIEC, and who owns the decision?
- Manufacturers with live-plant constraints, across the Carolinas and Southeast. Typical contacts include plant and operations leaders, facilities, EHS, and engineering, with owners or capital sponsors when investment decisions are on the table. You keep ownership of production and budget; we supply PE-accountable options and packages.
- Can you improve systems without stopping production?
- Yes. That is the default delivery rule. We phase mechanical packages into production windows and off-shift tie-ins, with acceptance criteria agreed before tools and vendors lock in.
- How do you measure results?
- Every engagement starts with a measurement basis the plant can audit. We do not claim percentage savings without that baseline. Typical waste or throughput opportunity falls in the 10-25% band when the data supports it.
- What is the first step and how long until a reply?
- Share facility type, priority constraint, timeline, and uptime rules via Contact or phone. You get a path recommendation, or an honest pass if we are not the right fit.
- Do you guarantee energy savings or 179D deductions?
- No. Results depend on facility, baseline, and scope. EPAct 179D is PE engineering documentation support where records support eligibility; tax filing stays with your CPA.
