JW Concrete Solutions LLC · DBA KO Mechanical Services LLCU of M Office for Supplier Diversity — Business Profile Narrative

JW Concrete Solutions LLC, doing business as KO Mechanical Services LLC, is a Service-Connected Disabled Veteran-Owned Small Business (SDVOSB) and union mechanical contractor headquartered in Hastings, Minnesota, serving the Twin Cities metro and western Wisconsin. We are a commercial and industrial pipefitting specialist — not a residential plumber and not an HVAC service truck — operating in the narrow lane where pipe meets equipment on real facilities. As a union contractor, we are qualified for prevailing-wage work, Davis-Bacon federal projects, and union-only jobsites.

For University of Minnesota Facilities Management — where we are already an approved vendor — our licensing stack is a major differentiator. We carry the credentials that regulated mechanical work on a U of M campus actually requires:

• Master High-Pressure Pipefitter License — State of Minnesota(the highest pipefitting license in Minnesota; most small contractors legally cannot hold it)

• Minnesota Mechanical Contractor License #MB100229• Minnesota Contractor License #IR803475• Minnesota High-Pressure Piping Contractor License #HC802574• ASME Section IX Certified Welding (pressure-piping code welding)

• City of Minneapolis Master Licenses:Gas Fitter · Oil Burner · Refrigeration · Steam & Hot Water

• City of Saint Paul Master Licenses:Gas Fitter · Oil Burner · Refrigeration · Steam & Hot Water

That credential stack allows us to legally and competently self-perform complex piping scopes behind a locked mechanical-room door on a U of M campus — including high-pressure steam piping and boiler tie-ins, hydronic and chilled-water systems, condensate return systems, heat exchangers, process and gas piping, compressed air systems, fuel oil and process fluid piping, pump installation, mechanical room rebuilds, equipment setting and rigging, and ASME-coded welding in carbon steel, stainless steel, copper, and specialty alloys.

We understand where our scope begins and ends. Refrigerant systems are piped by our team, while licensed HVAC technicians perform charging and commissioning — coordinated cleanly and professionally without scope overlap or misrepresentation.

Our company is built for responsive execution on specialty mechanical projects, shutdown work, system modifications, and difficult retrofit scopes that larger contractors often decline, delay, or delegate. Facilities supervisors work directly with ownership, master pipefitters, and experienced tradesmen during walkdowns, planning, and execution — not just estimators and sales representatives.

Representative experience includes work in industrial plants, commercial facilities, refinery environments, government and municipal infrastructure, manufacturing operations, mechanical rooms, and occupied institutional facilities involving complex piping systems, equipment installation, shutdown coordination, welding, rigging, and specialty mechanical construction.

Our team has supported projects involving high-pressure piping systems, hydronic and process piping, boiler and heat exchanger work, industrial equipment setting, mechanical retrofits, and facility infrastructure upgrades in demanding operational environments where safety, scheduling, communication, and execution standards matter.

Alongside KO Mechanical, our JW Concrete division performs the flatwork that supports those same facilities — sidewalks, curbs, ADA ramps, interior slabs, equipment pads, parking areas, entryways, and concrete repair or replacement. For facilities teams coordinating multiple scopes during compressed shutdown windows, this creates a single accountable point of contact, one mobilization, one schedule, and streamlined coordination.

What sets us apart is direct owner involvement, transparent bidding, disciplined scheduling, clean and safe jobsites, and respect for operational constraints, shutdown windows, occupied facilities, and after-hours work. We are not the largest mechanical contractor in the Twin Cities — we are the contractor that answers the phone, communicates clearly, adapts quickly, and stands behind the work with union craftsmanship and military-honed accountability.
