Hospital Chilled Water Plant: Classification Limits
A Louisiana contractor licensed in Building Construction wins a $3.2 million addition to a hospital in Lafourche Parish. The scope includes a 400-ton chilled-water plant, medical-gas piping, and a new electrical distribution system. The contractor plans to self-perform the chilled-water piping and controls, subcontract the medical-gas work to a mechanical contractor whose state license expired 60 days ago, and subcontract electrical to a firm that holds only a Lafourche Parish electrical license. The owner's construction manager objects.
The contractor argues that its Building Construction license lets it manage all trades, that the mechanical sub is grandfathered because it has worked in the parish for 20 years, and that the local electrical license is enough. The hospital is licensed and operating; the work will require shutdowns and infection-control measures.
1. Which license classifications are required for the chilled-water, medical-gas, and electrical scopes?
Read the worked answer
Building Construction does not cover specialty mechanical, plumbing or medical gas, or electrical work above the licensing threshold. The chilled-water plant and controls are mechanical work and require a Mechanical license; medical-gas piping is a distinct specialty, often a Plumbing or Medical Gas endorsement, and the installing contractor must hold the state license for that scope. Electrical distribution requires an Electrical license.
The GC may hold Building Construction and manage the project, but it cannot self-perform mechanical work unless it also holds the Mechanical classification. Each subcontractor must hold the appropriate state license at the time it contracts and performs. A local parish license is additional, not a substitute for the state license. The GC's license does not cover its subcontractors' scopes; the subs must be independently licensed.
2. Can the GC self-perform the chilled-water piping and controls? What if it uses the expired mechanical subcontractor?
Read the worked answer
No, not on the strength of Building Construction alone. Self-performing mechanical work above the threshold without a Mechanical license is unlicensed contracting, even if the GC is the prime. Using a mechanical sub whose license expired is also a violation; the sub is unlicensed during the work, and the GC cannot rely on the sub's 20-year history or grandfathering. Louisiana licenses are status-based and must be active.
The GC should verify the license through LSLBC before subcontracting and at performance. Consequences include LSLBC discipline against both the GC and the sub, possible invalidity of the mechanical subcontract, and payment risk for the sub. The owner may also treat the unlicensed sub as a contract compliance breach.
3. Does the Lafourche Parish electrical license authorize the electrical subcontract? What steps should the GC take before proceeding?
Read the worked answer
No. A parish or municipal electrical license is a local credential; Louisiana also requires a state Electrical contractor license for electrical work above the statutory threshold. The electrical sub needs both if the parish requires a local license.
The GC should obtain current LSLBC license certificates and classification confirmations from every specialty sub, verify the parish license with the local permitting authority, require the mechanical sub to reinstate its license before any work, avoid self-performing mechanical work unless licensed, and document the compliance file with the owner. The construction manager's objection is well founded. Proceeding risks stop-work orders, LSLBC complaints, and nonpayment for unlicensed work.
