Under the federal Miller Act, if a claimant is NOT in privity with the prime contractor, it needs to serve a “notice of nonpayment” within 90 days of its final furnishing. In this manner, 40 U.S.C. 3133 (b)(2) states:
A person having a direct contractual relationship with a subcontractor but no contractual relationship, express or implied, with the contractor furnishing the payment bond may bring a civil action on the payment bond on giving written notice to the contractor within 90 days from the date on which the person did or performed the last of the labor or furnished or supplied the last of the material for which the claim is made. The action must state with substantial accuracy the amount claimed and the name of the party to whom the material was furnished or supplied or for whom the labor was done or performed. The notice shall be served–
(A) by any means that provides written, third-party verification of delivery to the contractor at any place the contractor maintains an office or conducts business or at the contractor’s residence; or
(B) in any manner in which the United States marshal of the district in which the public improvement is situated by law may serve summons.
