First, the answer to Vol. 9 (last week).
Everyone nailed the water and electric combination! A true hazard no matter how you look at it, especially with the junctions being near or in water! Some other quality/safety observations include:
- Puddled water – diverting the water, drying the seam is required.
- The grinder laying on the geomembrane (in water). They should have a rub sheet under it. The disc should be dry and stay dry or you’ll be distributing moisture into the grind.
- Scraps of loose geomembrane. They should have been picked up the previous shift.
- Using a utility knife with a pointed blade to clean the contour roller of mud – no cut resistant gloves. As someone pointed out, this indicates the subgrade for the prior seam was probably wet, which it was, and which impacts the seam quality as the mud collects and builds up.
- No hardhat, although in 2017 (year of photo) this was still common practice on many sites.
Is anybody surprised the destruct failed? We had overnight rain, this was the conditions several hours into the shift. Everyone thought the installer would only do vacuum boxing on this day!
In these blog posts, Do You See What Glen Sees, I will present a photograph or short video related to earthwork or geosynthetics construction and have you identify the significance of what you’re seeing.
It could be things being done correctly or incorrectly. Primarily, these will be things that impact quality.
In addition to my blog, I’ll post this content on X and LinkedIn. You can post your response on one of those two.
I’ll give you my thoughts on each photo or video when I post the next installment.
Do you see what I see? Or did you find something I missed? I’m excited to find out!
Here is the next installment. Take a good look. Do You See What Glen Sees?
It’s hard to believe this already is the 10th installment of Do You See What Glen Sees?!
Do you ever get that feeling in your gut that something needs to be looked at or addressed on your project?
There are some obvious concerns here but the biggest issue seemed less obvious – so much so that I mentally battled with myself and even walked away before I finally decided to bring it to the attention of the owner, certifying engineer, installation foreman and earthwork foreman who were having a discussion near where the case of water bottles is at when I approached them about it.
Post your response on X or LinkedIn.
