PROBLEM TO BE SOLVED: To provide a civil engineering structure of excellent fire resistance preventing a fire from spreading to a foam resin block inside. SOLUTION: The civil engineering structure 1 is constructed by piling up main construction members 2 formed of foam resin blocks 4, and arranging exterior construction members 3 with cement hardened layers 6 formed at least on one surface side of foam resin blocks 5 outside the piled-up main construction members 2 so that the cement hardened layers 6 are on the outer surface side. As the exterior construction member 3, the peripheral edge of the cement hardened layer 6 is located inward from the peripheral edge of the foam resin block 5, and a cutout part 7 is formed at the peripheral edge. Further, a noncombustible member 15 is filled into a recess 14 formed at a joint part between the exterior construction members 3, 3 by the cutout parts 7 in the constructed state of the civil engineering structure 1.
