sidewalk contractors delight

Is it POSSIBLE that the City spent $5,000 per BLOCK to put in sidewalks along Huntinglodge drive? it is apparent that the only people who will HAVE any money to contribute to the gym project will be the contractors! If we are paying $5000 a block for SIDEWALKS, how much are we gonna pay for a 32,000+ square foot, trilevel building? I assume that those who contribute will get their OWN placques, right below Billys, and just a little bit smaller. How much is that concrete per yard? What are the standard costs?
