Foundation excavation assessment in Golden CO

• 0:01 - 0:30 All right, Jesse high-performance Earthworks down here checking out this job that we're asking to being asked to estimate would do this on time and materials as I explained because it is a foundation. There's a ton of moving Parts different trades that we gotta coordinate with so many variables and aspects are difficult to predict but that said we are going to go ahead and put an estimate together and here we got this is the street view. • 0:31 - 1:01 The job site here. This is a nice neighborhood street. Not too busy. Nice and wide nice curves. The houses are kind of mid-range. I would say in the market, you know, it's not the Ritz but it's also not the ghetto. It's kind of mid-level. This is a bank finance job with First Bank. They thought that it would be okay to do a 50% deposit on the job. I see. • 1:01 - 1:24 Explain the $500 scheduling deposit that we do here. We have Xcel Energy gas lines right here. We have a water main here and the sewer line there in green. The water main goes in here. The one question is is if we do need to upgrade the water line 2 inch and a half in order to. • 1:26 - 1:55 Supply the fire suppression system, whereas what we have now is a three-quarter inch so there may be a chance that we got to get into the road here and come all the way into the road and do a new water line and tap into the main so that would be some possible utility work make Tristan super happy. Then we got the sewer line here, which is basically right under there. We can see a little bit of settling on that trench right there and that sewer line is supposedly 9 feet down. • 1:55 - 2:01 Just inside the sidewalk probably right at crack give or take. • 2:04 - 2:32 And here's the main here. So but this sewer line should still be intact. So we shouldn't have to get into the road per se. We just need to dig down nine feet right here, which is plenty deep and pick up the existing sewer line and get that. So here's the water main or the the water supply in the meter and that is right there off the sidewalk supposedly. The driveway is going to come in here the garage is going to be. • 2:33 - 2:35 And over here, we'll look at the plans as well. • 2:37 - 3:04 The crap the garage is going to be a slab on grade right up at grade level here. One question that I have for the contractor is if we are going to want to do a construction entrance and perhaps cover this whole grassy area right here in front with vehicle traction control also known as VT C 4 to 6 inch crushed granite in order to keep the mud off the street that's going to be kind of up to the general contractor and the building District to see if that's going to be a requirement. • 3:06 - 3:35 So now we're kind of coming in here. We're going to have our garage is going to be read in here somewhere footprint. And then the house is going to be the majority of this lot. As a matter of fact, we have a 7 foot off set off of the property line basically coming in seven feet to hear give or take but with the soils engineer in the soils report, they're calling us for us to do a five foot over excavation. So that basically takes us to two feet from the. • 3:36 - 4:05 Property line and a huge variable and question mark is if we're going to have to do temporary Shoring because we're going to have a nine foot vertical cut right here. And that is going to be a unstable Cut Bank right here. So there's a chance that we're going to have to figure out we do need to get that question answered if there's going to be some temporary Shoring required and how will we achieve that that. • 4:07 - 4:26 Potentially destabilizing undermine the foundation of this house here. Whereas if this house does have a basement which it may cause you have that low window there. We may not have as big of a concern there, but that's definitely a concern for just the safety of the excavation and the concrete contractors. • 4:27 - 4:47 So here is where the previous basement got excavated and that's the whole we're left with all of the house has been removed as well as the concrete and that's the whole that's left. And then and that is not quite 9 feet down probably about 8 feet down. • 4:49 - 4:57 And then we're also going to have to dig down and over excavate an additional 12 inches under our walls and fit back filled with gravel. • 5:00 - 5:02 For our foundation footings. • 5:04 - 5:34 A question I have is if that's going to have to be over excavated in back filled with gravel at the bottom below the slab as well. Also radon mitigation. What's the what's the protocol there didn't happen to ask that at the time of my meeting with the contractor. So the excavation is basically going to come all the way back to here give or take by the time we add in that five foot of over excavation. It's going to come in all the way to here this temporary power pole. • 5:34 - 6:01 It's going to get moved back over to here. But so we're going to have to have all of this Dugout down to nine feet plus and then two feet from that fence line and two feet from that fence line all the way up towards the beginning of that excavation up there and then a little nub left in place there. So this is a lot a lot of dirt and I'm guesstimating this is going to be somewhere on the order of. • 6:02 - 6:25 700 yards give or take I'm thinking about 70 tandems that will have to be removed from here. Most of it will just have to leave and never come back because this is going to be a giant basement. But some of it will need to come back in order to backfill that 5-foot void down nine feet right up against the building. • 6:27 - 6:32 So I think that is the long and short of it. • 6:35 - 7:03 Erosion control and stormwater management during construction, perhaps some straw wattles down along this fence line or and or a self fencing and that will be called for by the civil engineer probably or maybe there's a protocol that's already spelled out in the building code of the building District that we're working with we can just do what they recommend so. • 7:03 - 7:08 This tree is going to stay all that grass in the back is all going to get. • 7:10 - 7:14 Damaged and removed so we can. • 7:17 - 7:46 Not worried about that. There's a whole Landscaping plan that will get developed for this. It's not been developed yet for now. We're just going to try to get these guys ready for concrete and tie in their utilities as well. So that is it. It looks like I just did a quick calculation guesstimating 70 trucks of export at $300 of load. Those are just some wild-ass numbers, but that's 21,000 just for Trucking of dirt away. Also, Brandon. • 7:46 - 8:05 For revolve design-build he recommended that I check out the dirt Guild here in Denver and see if there's a line on coordinating the transport of dirt. So I will check that out do a quick search and see what we can do. That's all I got. • 8:09 - 8:14 This is Jesse high-performance Earthworks. Subscribe to our Channel and check us out.
