My family and I will be in Kauai from 12/4-13 and the early weather reports look particularly stormy throughout next week. Is everyone else seeing the same thing?
Transformer Vault Construction. Transformer vaults are the concrete holding areas for the large transformers reducing high voltage power down to the lower voltage power for the area being served. The Robert Henry Corporations has over ten years or experience constructing transformer vaults and power substations.
Around 1050 AD, people began using a different kind of vault - the groin vault. It's called a groin vault because the parts meet together in a V, like the V where your legs come together. You make a groin vault by building two barrel vaults that cross each other, so that they make an X. A groin vault can be rounded, as in Romanesque churches, or pointed, as in Gothic churches. The main advantage of the groin vault is that it takes all the weight of the roof and concentrates it on just four points at the corners of each bay (each X).
