PROBLEM TO BE SOLVED: To provide a fiber aggregate for civil engineering works and construction, which is friendly for environment, such as the reduction in generated carbon dioxide, and can eliminate defects, such as inferior abrasion resistance, of products using polymers derived from biomass in comparison with products using polymers derived from petroleum. SOLUTION: This fiber aggregate for the civil engineering works and the construction includes conjugated fibers in which the cross-sectional shape of each fiber has a sheath-core shape, and a sheath portion includes a polymer derived from petroleum and a core portion is derived from biomass. The sheath portion of the conjugated fiber preferably includes polyethylene terephthalate, and the core portion preferably includes polylactic acid. In particular, the fiber aggregate for the engineering works and the construction include sandbags formed of woven fabrics, overland nets and safety nets formed of knitted fabrics, or the like.
