I’d like an explanation of how one can increase the thickness (not just the thickness, but the structural strength implied by the thickness) of poured concrete roadway/trafficway without tearing the whole freaking thing out and rebuilding it.

I believe that something similar happened with the Herndon/Monroe transit garage/park&ride in Fairfax VA. Place was only a few years old and needed major rework including drainage enhancements, resurfacing (and then overlaying with this weird rubberized compound) and installation of a LOT of very large steel I-beams.

I lived through that mess the Spring and Summer it was going on. They were shutting the garage down 1/4 at a time over the course of four to six months.

I had a construction lawsuit where the contractor was a design-build guy, which meant that they did both. Well, they subcontracted the structural steel design out to a guy who used a very green kid and didn’t check his work. Bottom line: after the concrete was poured, the floor had a belly in the middle (you could see that it was concave) and, if you looked at steel corrugate decking from below, you could see it buckled in a lot of places. Problem: inadequate sizing of I-beams for joists. Solution: We hired a structural steel expert who designed a system of welding plates to reinforce the joists at the critical load points. Once that was done, they poured a special floor leveling compound, to get the floors flat. Whatta mess.
