Yes, differences in the bottom level of footings is common. Single story buildings are more likely to have similar footing all around as they are supporting similar loads. As the height and weight of the building above ground increases you are more likely to see changes in the depth of the footing. Another commenter mentioned …

Most high rises are built to stand for 150 years. The oldest ones have hit that point and look like they can easily go for another 100 years with regular maintenance. But, most only seem to last for about 50–70 years before they are torn down and rebuilt with new high rises due to the …

If these are the only criteria, then yes. Basketball fans have expressed an increased need. On the other hand, medical use is on the decline. Assuming that medical needs had already been met at level not requiring a new hospital there is no additional need for a hospital if medical needs are decreasing. The problem …
The real answer has a lot less to do with physics and a lot more to do with politics. The real answer involves lock to lock steering rations, friction coefficients of tires, downdrafts, and car weights. But cars are all different with different levels of drivers. Yes, different levels of drivers. If you can’t figure …

Is it visually significant? Will it age well? Is it culturally significant? Is the designer aware of what it promotes, ignores, or ridicules? It will be a moment frozen in time. Does it look forward, to the past, or to the present? Who is commissioning this project? What do they stand for, represent, and how …
The resin needs to be exterior rated and UV rated (they may not be the same thing). Other than that it is application specific.
It would buckle under its own weight. Whether it broke into pieces would depend on the result of the buckling as it is very near the surface of the earth. But, in broad terms how big would it need to be to support itself. The circumference of the earth is between 24,859 – 24,901 miles. …
Houses have roofs design to shed water and snow easily with minimum maintenance over a long period of time. Commercial buildings have roofs that also shed water, but are designed so that, when possible, to have annoyance equipment (loud, hot,…) placed on the roof if they are not needed within the building itself.
Firstly, keep in mind that bedrock isn’t solid rock as most people seem to think, but any form of soil and/or rock that has developed cohesive forces within its structure. Secondly, you pretty much need tunnels to be going through bedrock otherwise you need to treat the soil as if it was a liquid. Most …
In addition to the costs mentioned in other responses, there is the issue of the materials that make up the building. These materials have been altered and possibly ‘stored’ in conditions which may alter their attributes. In order to reuse these materials they need to be reassessed and possibly tested. When compared to the ease …
