Strabag was one of the main profiteers of the Nazi building projects during Second World War and before. It was a main contractor of Todt organisation and built concentration camps, the Westwall and Norway´s Blood Road. The british secret service report concluded "[. . .] Enough large building firms offered their services so as to put the entire construction the Westwall, S.G. on a voluntary basis. [. . .] Nor is there any basis later for assuming that firms in any large numbers became so reluctant to work for the OT as to make mass conscriptions of such concerns necessary. This willingness is due to the attractive profits obtainable from OT contracts."
