PROBLEM TO BE SOLVED: To provide a construction installation guide method which easily and accurately measures in a short time a position of a construction, a working jig or the like in water from above a remote working vessel by using a wireless system without using a cable, grasps in a real time a positional relationship between an existing construction and a new construction, and can lead and install the new construction to a prescribed position.SOLUTION: By using a wireless system, a computer PC acquires distance information and depth information which are obtained by the measurement of distances and depths between transponders T1, T2, T3 and T4 performed by a pair of the transponders T1, T2 arranged in an existing construction, or a pair of the transponders T3, T4 arranged in a new construction. The computer PC grasps in a real time a position of the new construction in water from the information, leads the new construction to the existing construction, and performs highly-accurate installation. |
