To obtain a reinforcing woven fabric for a civil engineering building structure, excellent in-situ executability and capable of extending the selection width of a resin or a curing agent and to provide a method for execution of the civil engineering building structure.

This woven fabric comprises warp yarns 1 composed of at least reinforcing fibers and weft yarns 2 woven so as to wrap the warp yarns 1 on the outermost side and continuously reciprocate and turn back. The weaving width thereof is 200-2,000mm. The method for execution of the civil engineering building structure comprises impregnating the woven fabric with an uncured thermosetting resin, then applying the woven fabric to the civil engineering building structure or impregnating the woven fabric with an uncured thermosetting resin while applying the woven fabric to the civil engineering building structure.
