When it becomes necessary for the board of county commissioners of a county to erect or cause to be erected a public building, or a substructure for a bridge, or an addition to or alteration thereof, before entering into any contract therefor or repair therof or for the supply of any materials therefor, they shall cause to be made by a registered architect or registered professional engineer the following:
In connection with the planning and construction of any public building project, the board may employ a construction project manager or consultants, and fix their compensation. Such construction project manager or consultants shall be expert and qualified in their respective fields. The cost of such services may be paid from the proceeds of bonds and notes issued to pay the cost of such project.
This section does not prevent the board from receiving from bidders on iron or reinforced concrete substructures for bridges the necessary plans and specifications therefor.
