Gov'ts, civil institutions, educational institutions. They can't help themselves, seriously. They must make it a work of art for show: "this is how we spend your money" to the donors, taxpayers, etc. Then they can also brag about it, use it on resumes, etc. These things are not merely for efficiency/utility; it's got to be "significant" for bragging rights. Most of us know a steel 8 ft wide catwalk would be perfect: utilitarian, cheaper, much quicker to build and less prone to faults; problem is that it's ugly and no one wants to brag about it
