Why not share with the rest of us the inside poop on how a project like that is handled?I was on the surveying side. We placed a lot of curb, a lot of sidewalk, and the foundations for the platforms. The foundations for the platforms were by far the most involved elements of the construction process. The high plats required heavy equipment to bore the holes, heavy equipment to place the prefab support structures, and concrete pumpers to pour the platform slabs. By comparison the sidewalks, which even I've been able to build, were placed with far less effort on the part of the contractor. I've done both & it takes much more physical & mental effort in the field to pour a "sidewalk" than do a prefab job with footers. I'm sure these guys would agree with me. This comment screams of no actual experience doing the labor. What FredG said. A low platform is just a sidewalk with a bit of additional aggregate under it. |
