How to do Retaining Wall Bids, Estimates and Proposals

What happens here

Calculate the costs associated with removing existing structures and performing necessary excavation. For removals, such as an old secondary retaining wall and concrete steps, use a 'time and material basis' for estimation, converting this to a lump sum. For this specific project, the estimated cost for removing the initial wall and steps is approximately $1,760. For complex excavation tasks, such as digging back soil from a failing garage wall to relieve pressure, estimate the cost separately. This specific excavation to create a 4 to 6-foot gap behind the garage, hauling out approximately 46 tons (3 loads) of excavated soil, is estimated at $4,000. It's crucial to itemize these costs in the proposal to ensure transparency and proper billing.

Goal: Determine the cost for all demolition and excavation work.

teach you how to bid doing a job like that because the customer right next door wants the exact same thing done so what we're going to do is going to break this proposal down into removals excav a and then retaining wall installation and a couple of the details that we need to take into consideration is the joint space from one wall to the next now we're going to be using the same Block in this very specific case but we're going to have to stitch this wall together and you've seen my maybe you've seen my other video where I talk about retaining wall installation but on this project what we're going to be doing is we're going to go from the base and then we're going to remove this wall up at an angle so that this is removed and then when we build this new wall We join them together and eliminate this seam so how do we go go ahead and start calculating this thing down well the first thing we're going to look at is the removals now in this case there is no magic mystery formula that's going to solve this problem for you so you have to look at this and you're going to use a time and material basis it's going to be a lump sum you're going to have to be careful you're going to have to base It Off from experience on this very particular project our removal cost is going to run about $2,000 to remove this retaining wall to remove these steps and to get this dug back far enough that we can get our drainage material and our um base course in then we're going to also measure the
