“pass for the construction service” functioning in the GG between May 1940 and the summer of 1944, modeled on the German labor service (Reichsarbeitsdienst). In fact, the construction service was a kind of slave labor. It was regulated by a decree and it was in practice from 1 of December of 1940 to 22 of April of 1942. The construction service lasted for a year and involved the young men who were then employed in public works, works for the army, and also burying victims of mass executions, etc. At its peak the construction department numbered 45 thousand Baudienst employees (January 1944). The Baudienst employees were living in camps. This isolation had the goal of preventing involvement in underground activity. In case of offense or escape they could be deported to special camps, or to a penal services building near Krakow (quarries, “Lebanon”) or in Solec Vistula.
