A plate structure block for establishing a surface layer ground is formed integrally with an iron plate on an upper surface of a reinforced concrete member. A lift metal fittings for transporting the block is installed on the block. The surface layer ground establishment block has a large ground bearing pressure and is a portable block. This block is covered on the surface layer ground and establishes the ground for operating a heavy material machinery and/or for maintaining a heavy material member. By operating a mobile heavy crane on the established ground, the working for constructing a plant is carried out. The material for constructing the ground is reused, the shape of the ground site is easily changed, and the dismantling and removal of the ground is simplified.
