On April 8th, the City of Los Angeles' Mayor, Eric Garcetti, issued a "Worker Protection" Public Order to greatly expand the requirements for wearing non-medical grade face coverings. It does not specifically mention construction site workers, but it is BIA-LAV's recommendation that wearing non-medical face coverings be a best practice for construction workers and anyone else coming into contact with others during the normal course of their day. Keep in mind that this does not strictly require masks; it can also be bandannas or some other type of creative covering.
