Historian Nikolaus Wachsmann states that Kammler "was intimately involved in all the major building projects in Auschwitz." For instance, in his capacity within the WVHA, Kammler oversaw the installation of more efficient cremation facilities at Auschwitz-Birkenau, when the Nazis converted it into an extermination camp. Under Kammler's supervision, new crematoria were planned during August 1942 at Birkenau to facilitate burning up to one-hundred twenty thousand corpses per month.
