Construction Erosion Inspection-Trench Excavation Asphalt Kept Clean

Dirt loaded into front loader bucket and hauled to stockpile, or dirt side cast onto asphalt: which is cheaper? How about no sweeper needed, no dirty water going down the drain. I go with the first answer.

Not What an Inspector Wants to See

I just did a quick, random, drive-by of a job and this is what I saw. This might tell me that the construction staff, owner and contractor, don’t understand what is required or, haven’t read the TESC specifications.

Since this was a random, unannounced, drive-by, I might think that this is not an isolated incident. While I prefer a site be kept clean, as long as stuff doesn’t leave the project boundary, I don’t have an issue. However, by not keeping the site clean, trackout is inevitable.

Also, note the Bobcat broom sweeper just inside the fence on the left; these are great for pushing dirt around and up in the air but we only allow vacuum sweepers on projects, so I don’t know why this is on site.

I sent an email to the engineer suggesting that everyone might want to review the TESC spec. and take necessary actions so this doesn’t keep happening. Also, rain is forecast for tonight.

Inspecting-Check Dams Need Low Center Point

Check dams need to be installed so that the center point of the dam is at least 6 to 8 inches lower than the outside edge; 12 inches in areas where intense rainfall occurs. If the center point is higher than the outer edges, water will run around the dam and erode the side slopes of the ditch, causing erosion. If the ditch is shallow and you are using triangular silt dikes, you might need to add sand bags to create a center point that is low.

Inspecting Plastic Sheet Installed on Slope

Plastic sheet is a good, temporary practice you can use to protect soil from soil erosion and sediment loss from a slope. When used, you need to make sure that the plastic is installed so that all the clean rainwater that runs off doesn’t end up dirty because it ran onto bare soil. The clean water needs to be collected and piped away from the bare dirt, or the plastic needs to be run all the way to the bottom of the slope into a stable ditch covered with grass, erosion control blanket, rock or other soil erosion prevention measure.
