Estimate Retaining Wall Construction

you want to be as close as you can because then if you're way off and you you come with them with a number and you're now you're adding $155,000 to the project because of something you missed well that's not going to go so well either so it's going to scare him away it's going to you're going to want to be close all right Tim now as we look at this retaining wall Tim was actually here when I was building building it now Tim was running a different site for the most of the time but as we were building this retaining wall I actually had a crane so when I was doing the original numbers on this job you see that power pole right there I had an actual crane come out and hold that power pole in place hover it above ground because as we were digging we had to dig back for geogrid to install this retaining well we had to actually dig back right up to the alleyway we actually had to get a permit to use the the easement of the alleyway and we had to hold that that thing up with the crane now as you look at this retaining wall to what are the factors you take into consideration when you bid something like this when you bidden you got to first get your figure out okay is it over 4T yes well that's going to require engineering so now everything we've talked about with the soils and stuff here you're going to want to there's going to be a site plan most of the time for for for a project like this this is already and it's going to have your proposed grades um next to your existing sometimes they're overlaid on the plan so then you can take do a takeoff of that too and figure out how much soil is coming out based off of the plan so it gets you even closer so now if this is residential you don't always have a survey you don't always have a situation so now you got to take do your measurements and and figure out you know the the the divided by 27 get your get your numbers that way so so and in a retaining wall like this though we've got to calculate the actual square footage cuz they don't give us the square footage on the plan this had a blueprint and it had just bottom of wall elevations and top of wall elevations and we have to actually go through and hope and pray that the surveyor got all of their elevations you want to double checks you get your wheel out and you get your height of the you know you know the height of the wall some cuz with when you're coming here to measure this initially you you have a hill here so how you going to tell where that wall you know height…
