In Prime Mechanical Service, Inc. v. Federal Solutions Group, Inc., 2018 WL 619930 (N.D.Cal. 2018), a prime contractor was awarded a contract to design and install a new HVAC system.  The prime contractor subcontracted the work to a mechanical contractor. The mechanical contractor with its sub-designer prepared and submitted a new HVAC design to the prime contractor and provided 4-5 onsite services to determine the location and layout for the new HVAC equipment, perform field measurements, obtain security passes, and plan site access and crane locations.  The mechanical contractor submitted an invoice to the prime contractor and the invoice remained unpaid for more than 90 days, which the prime contractor refused to pay.  The mechanical contractor than filed a Miller Act payment bond lawsuit.


The prime contractor and surety argued that the mechanical contractor had no valid Miller Act payment bond claim because it was seeking professional services and not the labor covered by the Miller Act.   The trial court agreed. 


As used in the Miller Act, the term “labor” primarily encompasses services involving “manual labor,” or “physical toil.”  Although “work by a professional, such as an architect or engineer” generally does not constitute “labor” within the meaning of the Miller Act, some courts have found “certain professional supervisory work is covered by the Miller Act, namely, skilled professional work which involves actual superintending, supervision, or inspection at the job site.”


Prime Mechanical Service, Inc., 2018 WL at *3 (internal citations omitted). 


The mechanical contractor attempted to argue that it was onsite and the onsite services it performed should constitute “labor.”   However, the onsite services the mechanical contractor identified were clerical or administrative-type services which did NOT involve “the physical toil or manual work necessary to bring them within the scope of the Miller Act.”  Prime Contractor Mechanical Service, Inc., 2018 WL at *3.  


In this case, the mechanical contractor gave it a worthy go to support a Miller Act payment bond claim. But, because the services it performed did not rise up the type of “labor” covered by the Miller Act, it was out of luck.   Had these services been coupled with actual  manual labor at the site connected to the installation of the new HVAC system, the result would have been much different since the mechanical contractor would have performed “labor” covered by the Miller Act.
