The Atlantic Wall was constructed in less than two years. This unprecedented achievement was only possible due to the efficient style of construction. The Germans used standardised bunker designs named 'Regelbauten' when building the Atlantic Wall. Hundreds of type standards are known, each with its own unique name and type number, listed in special bunker catalogues, named 'Typenheften'. Each entry is accompanied by technical drawings and details of materials and labour required to complete construction. Small, lightweight bunkers required over 100 cubic metres of concrete and an St-bunker around 800. Common examples of St-bunkers are the 610 (command bunker), 502 (barrack bunker) and 134 (munitions bunker) types. The 'Festungspioniere', Germany's military engineers, were given the specific task of designing bunkers and fortifications and determining the best sites to build.
