Every person, natural or artificial, who has worked as a worker or employee on, or who has supplied, sold, or delivered materials, equipment, and tools for, the work referred to under § 47 of this title, with regard to which work the bond required by §§ 47—58 of this title has been posted, and who has not been paid, in whole or in part, as required by §§ 47—58 of this title, his salaries or wages, or the price of the materials, equipment, and tools sold, delivered, or supplied for the work, shall have the right to file suit, without necessity for previous notice, against the contractor, against the bond of the contractor, against the bondsmen of the contractor, or against any of said bondsmen, for recovery of any amount which may for such reason be owing him. Any person or persons who have a direct contractual relationship with a subcontractor on the work and who have or do not have an expressed or implied contractual relationship with the contractor on the work, who has posted the bond, may institute action against the contractor, the bond of the contractor, the bondsmen of the contractor, or against any of the said bondsmen, for the recovery of all or any part of: (1) any amount which may be owed them by the subcontractor for salaries or wages they have earned as employees or workers of the subcontractor on the work; and (2) any amount which may be owed them by reason of their having supplied, sold, or delivered materials, equipment, and tools for the subcontractor on the works. Suppliers or sellers of materials, equipment and tools to the subcontractor shall be obligated, before instituting action against the contractor, his bond, or his bondsmen, to notify the contractor, by registered mail, of their claim. At the expiration of thirty days from the mailing of the said notice they may institute the action herein authorized. Workers and employees of the subcontractor may institute action at any time without previous notice to the contractor of their claim. In all other respects they shall abide by the rights and remedies granted by §§ 47—58 of this title to the workers and employees and the suppliers of materials, equipment, and tools, of the contractor and the liabilities imposed by § 47—58 of this title shall apply to the contractor, his bond and his bondsmen.
