Okay, it's time to build a retaining wall. What you're going to see behind me is a wall that we built a few years ago for a customer in a site in Minneapolis. We use the Versa-Lock standard units on this course. The customer did their own secondary retaining wall using a different block, which I wouldn't recommend doing. However, they did this after the fact and it was out of our control. When you look at this garage, you can see where we actually had to dig back the soil to sneak a wall in behind it, keeping the pressure off from the yard. Today, I'm going to teach you how to bid on a job like that because the customer right next door wants the exact same thing done. So, what we're going to do is break this proposal down into removals, excavation, and then retaining wall installation. We also need to consider the joint space from one wall to the next. While we'll be using the same block in this specific case, we'll have to stitch the walls together to eliminate any seams. We'll start calculating this thing down, beginning with the removal. In this case, there is no magic formula to solve this problem, so we'll have to base it on time and materials, using a lump sum. Based on experience, our removal cost will be around $2000 to remove the existing retaining wall and dig back far enough for drainage material and the base course. Next, we'll measure the retaining wall. We'll break it down into its simplest components and calculate it on a per square foot basis. This will help us determine exactly how many square feet we have in this wall and format our proposals accordingly. Another component to consider is excavation. The garage wall...
