These can be built in high-intensity, since they require no tools or blueprints. Hot-ground tunnels are actually excavated and filled with electrical material. They are usually either set aside or put down in shady, warm or dimly lit spots. They will provide shade for insects and animals. Small tunnels: no smaller than 1 m. Natural tunnels: no larger than 3 m. These tunnels require support at the openings to keep the tunnel from collapsing. These tunnels are usually shallow and used for subways, water delivery, and wastewater removal systems.
