Construction Entrance Fail

This is a 30 + acre site with one access point, this one. If this was my project, I would have specified a tire wash with an asphalt exit to the street. The tire wash would have been long enough for two tire rotations, have high pressure, low volume nozzles located such that all tire surfaces were sprayed. This system would also have an on-board, treatment polymer injection system to keep the tire wash water relatively clean. I would have specified that the water be tested for turbidity daily, measured at 50 NTUs or less. Since the water is classified as “process water”, I would have required it to be tested for metals and other contaminants, then hauled to an appropriate disposal facility.

Prevention is the cheapest way to keep tires clean.

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.

That’s Some Fancy Rock Construction Entrance

I saw this on the way to work and thought it was amusing on the surface. Really, though, I think they needed the elevation to access the upper part of the site.
