Civil CNC, when mechanical engineering collides with Civil engineering

Civil Engineering and Mechanical engineering

When this collision between civil engineering and mechanical engineering happens it’s not about a fight nor a competition between my friend who is a skilled civil engineer specialist in structural analysis and me but a synergy of these two fields that intersect to give birth of a new conceptual and artistic way of building small to big buildings right on a block of rock or on a more malleable block of materials like plater using this tool known by mechanical engineers that are used to manufacture so many pieces and parts of our everyday life. This tool is a Machining Tool like this DMG Mory CNC.

This idea could be a conceptual idea that may not be linked to specific actual needs both for the mechanical and civil industries but I thought that it could be an interesting artistic experiment for architects and builders willing to create a creative building using an uncommon way of building. The idea said precisely is about machining a whole beautifully designed architecture of a building on a block of plater using a very big machining tool.

The project behind this idea will be two folds because given the size of the final building a set of small and big machining tools will need to be designed and manufactured and a giant block of plater molded in a cubic form in order for the construction phase to start with the setup of the machining tools that will carve out the volume of materials on the block of plater for the building shown on the cad file to take its form drill bit by drill bit. There will be of course a huge volume of materials that will need to be processed as waste but I think that plater is a very easy material to recycle.

Also, I don’t know how the strength of the finished building will be as I do not have the time and probably not the skill to go into the strength and corrosion analysis (water) of this whole building made in plater but may be civil engineers like my friend could help. as an unskilled mechanical engineer, I am imagining that a surface treatment could be applied to these finished building in order to make it waterproof and strong enough to be able to host what could be thousands of persons visiting buildings like these designed by skilled Architects like Frank Gehry.

This kind of exotic way of building buildings has no economic sense from my actual point of view. I just see it as an artistic engineering challenge for those who like challenging things. May rich people and organizations who like artistic engineering challenge could like this idea and fund it for fun but who know? Maybe if it’s studied enough, one could find out that there is a bit of economic incentives to build buildings like that again given that the strength analysis signal says that this will resist all the efforts that will be applied on its surface.

You see that with this idea, I have intersected how mechanical parts like gears and components of cars and nuclear reactors are manufactured with how buildings like homes, offices, and other public and private ones are constructed. how tunnels are carved in rocks of mountains with this

How tunnels are carved in rocks of mountains made me think that maybe this is not a so foolish idea for one who has the means and time to go for it.

I don’t know if you do but I have written this just for the sake of sharing ideas and this one was waiting there on a blank piece of paper with this only written on it: Civil CNC, when mechanical engineering collides with Civil engineering. This is certainly the last week today I read it again because I was digging in my pile of paper and thought that it was worth writing it and sharing. Then it’s done I hope it will serve you if it doesn’t then I am sorry for disturbing you with words that serve nothing.
