The commissioner may with the approval of the state board, at a time to be fixed by it, select by competition from among the architects legally registered in the state, an architect to design any specific building or structure. The designs of the competitors shall be judged by a jury of three disinterested architects, one selected by the state board, one by the competitors and the third by the two so chosen.

Should the jury discover among the competitors any whose designs indicate an ability to solve the problems acceptably, it shall certify its first choice to the commissioner who shall appoint him as associate of the chief of the division of architecture and construction to design the specific building or structure.
