Latitude [degrees] Longitude
Site classification (EC8) A B C D E
Topography T1 - flat surfaces, isolated cliffs and slopes with average slope angle not greater than 15° T2 - slopes with average slope angle greater than 15° T3 - ridges with crest width significantly less than the base and average slope angle between 15° and 30° T4 - ridges with crest width significantly less than the base and average slope angle greater than 30°
Nominal life [years] 10 years - temporary structures 100 years - important structures 50 years - ordinary structures
Building functional type 1 - provisional structures (Cu=0.7) 2 - ordinary structures (Cu=1.0) 3 - important structures (Cu=1.5) 4 - strategic structures (Cu=2.0)
