HVAC mechanical, sheet-metal, and refrigerant-piping sub-trade rotated across the MELCO retrofit, the Carlson hardware buildout, Regal Rexnord Browning, Wald LLC, and Meadowview hospital MEP.

The MELCO retrofit drives a defined MEP rough-in and commissioning window. The $143.5 million retrofit carries process piping at the compressor-assembly cells, A2L-rated refrigerant piping, HVAC mechanical and dust collection at the rotary-machining bays, sheet-metal at process ductwork, industrial-electrical and controls at the variable-speed test stands, low-voltage cabling for plant SCADA, fire suppression at the refrigerant zones, and commissioning across all major systems ahead of October 2027 first production. The EPC or general contractor prime identity is not publicly disclosed as of May 2026; Maysville-resident sub-trades capture the dispatched-crew-hour portion of Tier-2 and Tier-3 scope downstream of the prime.

Carlson Software's adjoining-property buildout is a parallel demand leg. The May 2025 land purchase expands precision-measurement-instrument manufacturing capacity. Tenant fit-out at the adjoining property carries mechanical, electrical, and HVAC scope sized for a four-to-eight-person shop, distinct from the much larger MELCO scope and useful through 2026 and 2027. Buildout size, schedule, and contractor selection are not yet public.

Regal Rexnord's Browning plant generates recurring maintenance and outage work. The plant runs forming, machining, heat-treat, and finishing equipment on predictable annual maintenance windows. The current bench sources from Cincinnati, Lexington, and Maysville contractors. A Maysville contractor with NFPA 70E, Allen-Bradley, and Siemens controls fluency plus same-day mobilization fills recurring and outage-surge demand against contractors mobilizing from outside the labor shed.

Wald LLC supports steady-state facility services across 300,000 square feet. The continuous-since-1924 stamping and finishing plant carries press, paint-line, finishing-line, and facility-mechanical demand. Single-anchor concentration is kept moderate. The Wald leg supports recurring monthly dispatch revenue without depending on a major capital cycle.

Meadowview Regional Medical Center adds commissioning and facility-services adjacency. LifePoint Health operates the only acute-care hospital within roughly thirty miles, serving Mason plus the no-hospital cross-river catchment of Brown and Adams counties in Ohio. Service-line capital projects, facility services, medical gas, HVAC, and controls maintenance compose recurring small-engagement work compatible with a four-to-eight-person shop carrying ASSE 6010 medical-gas, NFPA 99, and arc-flash credentials.

The rotation is credit discipline, not branding. A founder who places only on MELCO scope and treats the other four anchors as fill work runs single-customer concentration above the 60 percent threshold that triggers SBA 7(a) banker auto-decline. The five-anchor rotation — MELCO, Carlson, Browning, Wald, and Meadowview — is the structure that keeps the lane financeable through senior-debt underwriting.

Per-engagement scope. A MELCO retrofit MEP rough-in mechanical-and-sheet-metal engagement runs four to eight weeks with a four-to-eight-tradesperson crew on process piping, refrigerant piping, and sheet-metal scope under SMACNA discipline, EPA Section 608, A2L-refrigerant handling, and arc-flash documentation: $80,000 to $320,000 per engagement at three to six engagements across the 2026-2027 rough-in and commissioning ramp. A Carlson tenant fit-out engagement runs two to six weeks with a three-to-five-tradesperson crew on bundled mechanical, electrical, and HVAC scope: $40,000 to $160,000 per engagement at one to three engagements across 2026-2027. A Regal Rexnord Browning planned-outage engagement runs one to three weeks with a three-to-six-tradesperson crew: $25,000 to $110,000 per engagement at four to ten engagements per year at maturity. A Wald LLC recurring monthly facility-services dispatch: $4,000 to $18,000 base per month plus per-engagement billing. A Meadowview small-capital service-line engagement: $20,000 to $90,000 per engagement at four to twelve per year. An annual master-services-agreement retainer at one to three of the five anchors: $36,000 to $120,000 per retainer plus dispatched engagement billing.

Year 1 (founder plus part-time bookkeeper; six to ten dispatched engagements skewed toward Browning, Wald, and Meadowview recurring scope plus first MELCO rough-in mobilization plus initial Carlson buildout): $400,000 to $900,000 revenue base. Founder take-home $60,000 to $110,000.

Year 2 (ten to eighteen dispatched engagements with the MELCO commissioning ramp, Carlson buildout completion, and one to two MSA retainers; staffed foreman plus controls technician): $900,000 to $1.8 million revenue base. Founder take-home $100,000 to $170,000.

Year 3 onward (fifteen to twenty-five dispatched engagements, two MSA retainers, the MELCO commissioning tail, and steady-state recurring work across Browning, Wald, and Meadowview): $1.6 to $3.0 million revenue base. Sustained founder take-home $140,000 to $220,000. Above $220,000 requires expansion into prime master-vendor scope at MELCO or Regal Rexnord, outside this lane.

Founder-side capital $200,000 to $580,000. Service truck, dispatch trailer, brake and shear, Fluke and Megger test equipment, arc-flash PPE, LOTO, and refrigerant-recovery equipment $40,000 to $90,000. Allen-Bradley and Siemens controls programming workstation plus service-relationship subscriptions $10,000 to $25,000. EPA Section 608 universal, state mechanical and electrical licensing, SMACNA, NFPA 70E, BCxP/NEBB/AABC commissioning credential, and ASSE 6010 medical-gas credentialing $12,000 to $35,000. Errors-and-omissions, general-liability, and workers'-compensation insurance at the industrial-trade band $25,000 to $55,000 a year. Office and light-industrial shop bay lease, IT, and document-control system $20,000 to $50,000. Crew-build recruiting plus 90-day payroll float for four to eight tradespeople $50,000 to $170,000 initial reserve. Twelve-to-eighteen-month working-capital reserve $40,000 to $155,000.

Family-capital deployment plus SBA 7(a) lending is realistic at the lower end of the range; a small ROBS or equipment-finance overlay extends the upper end.

The founder is mid-career industrial trades with one of two profiles. Either industrial-mechanical-contractor operations-manager tenure with SMACNA discipline, EPA Section 608 universal, A2L-refrigerant handling, and willingness to add a controls-and-electrical journeyman as the first hire. Or industrial-maintenance-superintendent tenure at a regional power-transmission, stamping, or specialty-manufacturing operator with master-mechanical credential, arc-flash, ASSE 6010 medical-gas, and commissioning familiarity. Mason, Bracken, Fleming, Lewis, Brown County OH, or Adams County OH residence plus recruiting reach into Maysville, Cincinnati, and Lexington industrial workforce materially lowers customer-trust friction across the five anchors.

Relationship-portfolio target at launch. MELCO HVAC US Maysville plant-engineering and the EPC or GC prime project manager. Carlson Software facilities for the adjoining-property buildout. Regal Rexnord Browning plant maintenance superintendent and outage coordinator. Wald LLC facilities manager. Meadowview Regional Medical Center plant operations director. Maysville-Mason County IDA tenant-introduction lead and the Kentucky Cabinet for Economic Development incentive-package coordinator. MCTC Industrial Maintenance, HVAC, and Welding program coordinators plus the KCTCS Workforce Solutions in-demand-occupation lead. The Buffalo Trace ADD executive director and the WIOA pass-through coordinator. The AKA-MEP regional director. IBEW Local 369 and SMART Local 24 apprenticeship coordinators. The SBA Louisville District Office. Twelve to twenty named contacts by the end of Year 1.

Entity and credentialing posture. Kentucky mechanical-contractor and electrical-contractor licensing, master-mechanical or master-electrician credentials, EPA Section 608 universal, A2L-refrigerant handling, SMACNA, NFPA 70E, arc-flash-study capability, a BCxP, NEBB, or AABC commissioning credential, ASSE 6010 medical-gas certification, OSHA-30 across the crew, and LOTO program documentation. A broker relationship with a Northern Kentucky or Cincinnati industrial-trades broker structures the E&O, general-liability, workers'-compensation, and umbrella stack at the industrial-trade band.

The practice operates as an owner-operator multi-anchor sub-trade contractor with controls and commissioning overlay. No rollup arithmetic, no add-on EBITDA multiple. National multi-trade industrial-services firms — Day & Zimmermann, Limbach, and comparable — bid prime master-vendor scope at major commissioning windows where engagement size absorbs their cost structure. The regional Tier-2 and Tier-3 sub-flow sits below the national-vendor pricing floor and below the same-day mobilization radius national firms cannot match from out-of-region depots. A Maysville-resident contractor of record carrying single-interface coverage across the five anchors is the shape national platforms cannot replicate without the same regional bench they have no reason to build.

• — The EPC, construction-manager-at-risk, or general-contractor prime running the MELCO retrofit; the Tier-2 sub-trade pre-qualification schedule; and whether Maysville-residency is a stated criterion. Highest priority: this gates whether the founder can place on the MELCO bid list.
