PROBLEM TO BE SOLVED: To eliminate unnecessary increase in a rate of solidifying material to anticipate safety in a need soil cement construction method where conventionally an FC strength of a land forming body constructed in an empty space could only be measured after the land forming body is solidified. SOLUTION: In this soil improvement construction method, the empty space is formed by excavating and discharging soil of the ground, excavated soil, the solidifying material, and water are put in the empty space at predetermined rates, the materials are mixed and stirred in the empty space and the soil and solidifying material mixed slurry is solidified. The FC strength of the land forming body to be constructed can be estimated while in a slurry state by sampling a sample slurry from the slushy soil and solidifying material mixed slurry mixed and stirred in the empty space, measuring a flow rate of the sample slurry, inspecting a water content rate inside the soil and solidifying material mixed slurry, measuring a specific gravity of the sample slurry, and inspecting a solidifying material rate inside the soil and solidifying material.
