Urinals supplement WCs for male users, reducing WC queue times. The progressive schedule ensures small offices aren't over-equipped while large offices have enough fixtures to handle peak load.
Most workplace drawings follow this exact schedule. Above 100 persons, designers add 1 urinal per additional 50 male users.
