Bridges / Platforms
Allow for the construction of concrete slab platforms that would visually be similar the the large slab the shipyard has. These platforms would be constructed on the ground taking up one unit of depth in the game and would allow the ground underneath of them to be mined out safely without the platform collapsing. This would allow for structures to be built on top of underground ore deposits without preventing the ore from being mined. The most obvious use would be constructing bridges in advance to allow for better traffic of trucks and/or pipes across quarry pits and even allow for structures like coal power plants to be build on top of an existing coal deposit. The balancing feature of these slabs is that they must be made on top of already existing terrain as to not make it too easy to construct bridges of other islands or spanning gaps.
