PROBLEM TO BE SOLVED: To provide a device for constructing a viaduct right above a foundation, for reducing cost and shortening a construction period using generally-used members mainly in erection of a girder. SOLUTION: This device includes: a construction device 16 for foundation work, which performs substructure work such as construction of a pile; and a construction device 18 for erection of a member, which perform superstructure work for the viaduct 14 etc. on the foundation work. Each of the construction devices 16 and 18 includes: lower girders 20 and 21 which are movably supported on a pile 24 or a stand pipe 26 for driving the pile which are precedently constructed; and upper girders 22 and 23 which are movably supported on the lower girders 20 and 21. The construction device 16 performs the construction of the pile 24 or the stand pipe 26, and the construction device 18 places a precast member in a predetermined position.
