Elongation Report

Reviewing Elongation Reports

At this point, I think it’s fair to say that I’m a proponent of post-tensioned structures.  I’ve found that they can be very economical, and there are many things you can only do with post-tensioned concrete.  However, there’s one point that I think all structural engineers agree on: while post-tensioning is a great tool to have …

When the use of a building changes from one occupancy to another, say a store to a restaurant, you certainly need an architect to help you. The architect deals with exiting, fixture counts, layout issues and provides the stamped plans that you’ll need for the building department. When that change happens in a space that …
