The caution tape they laid over the pipe has an additional important use you didn't mention. It's metallic, meaning you can trace the plastic pipe above ground with a metal detector without having to blindly dig around to find it

In simcity, water treatment connections only take a few clicks. These three videos really showcase how complicated civil engineering can be and how out-of-sight it is to our daily lives.

[@PainterVierax]

city builders are often far from simulation. They are gestion/puzzle games. Otherwise they would include induced demand and other real-world mechanics that leads the player to make proper urban planning. Ironically, those with a non-contemporary theme are those forcing players to create mixed-zoning.

[@stevens9625]

@@PainterVierax I wonder with the current hardware and the popularity of sim games like farm sim, trucking sims and kerbal space program, a civil engineering sim would be too far fetched an idea. There's probably as much complexity in building a freeway as there is building a space station.

[@PainterVierax]

@@stevens9625 I've never played farm or truck sims but I can imagine they simplify and gamify a bit. Otherwise they won't be categorized as videogames. For a more obvious example, look at the difference between games about making art (painting, music, etc.) and proper creative tools. Kerbal is kind of an oddity, without crowd founding and the massive eager for a theme like space this game would never be a reality. After all, people like their games. They don't want to feel like it's real work, by making maths, waiting for stuffs, etc. I'm not entirely sure about the complexity of building a freeway but It can't be as engineering intensive as a space station or even a plane. There is much more tolerance to imperfections and rectifications for the former.

Weirdly cute seeing the pipe tied to the excavator's neck with a great big ribbon. And that caution tape above the pipes is so thoughtful! I love little things like that that show how people create procedures to make other people's lives easier.

[@xraybox]

To be fair, the caution tape isn't because they're thoughtful, it's because of too many painful instances where water/sewer/gas/electric pipes/lines were compromised by excavation, building codes started mandating specific indicators and their heights above said pipes/lines ;)

[@Kashed]

I can’t tell you how many miles of underground work I have witnessed while being an RE for a water and wastewater consulting firm. These guys had it easy only having to leak test with water instead of having to vac test not only the lines but, also every manhole. Plus using pvc makes it so much easier. Try miles of 36” concrete water main through suburban subdivisions, under creeks, rail, and dealing with homeowners!

[@ConstantlyDamaged]

Gotta appreciate the skill of the people in those excavators. I've seen these people juggle eggs in their buckets without breaking them. They are surgeons.

[@usopenplayer]

Those screw-tightened rubber seals are very interesting. I always thought there would be more permanent seals, but those seem really nice. I'd love to learn more about seals in general. Hydraulic Press channel recently tried to create alternative ice structures using high pressure, and he ran into some issues with sealing.

[@vasiliigulevich9202]

There is so much rubber in this whole project. Why would it hold for more than 15 years is a mystery to me.

[@DavidBezemer]

Underground life of rubber is much longer as the main cause of deterioration of rubber is UV light which doesn't reach underground.

[@CGT80]

Watch Farmcraft 101 He works with seals in hydraulics, carburetors, etc. but will sometimes overly an image of an injured "seal" on the screen 😁 Turns out, the spelling is the same as well. He finds some cute animal pictures. I thought they would grout the penetrations. I have done some repairs with 6 and 8 inch pvc pipe like that for water feeds in a golf course that sat over a landfill, but had not seen that type of rubber seal. HDPE is another pipe I have used, but we fused it together. The rubber seal is a good idea.

[@Nevir202]

​@@vasiliigulevich9202 I had a pair of tires on a car under my carport that I never drove. The tires were almost 18 years old when I sold the car and still holding air. The rubber here is much thicker and isn't going to experience any pressure. Worst case in a few decades, the rubber will be pretty hard, but that doesn't really matter, unless the pipes are moving. And if the pipes are moving you have bigger problems than your seals.

[@ihd-3603]

Pipes might move some from normal ground shifting but not much.

I didn't even know CAD techs *were* a thing until quite recently, I just assumed engineers drew the drawings.

Wouldn’t flowable fill be expensive compared to using what’s there? Unless the original soil wasn’t very good for fill.

@@ihd-3603 It would be hard to say what would be the best approach without seeing the geotechnical report and other information, that would dictate what’s used more than anything. In my region that much flowable fill would be too expensive to use, but it may be cheaper in southern Texas.

@@ihd-3603 In a previous episode Grady said the soil was mostly clay which isn't suitable. Clay expands and contracts a lot depending on moisture and temperature.

[@RonakDhakan]

I was so confused by the manhole process that I thought they left the old and new pipes unconnected and filled around them completely. Now I know the old pipe will be cut and the empty space left in the manhole will redirect the sewage to the old and new pipes.

[@DylanClarkSallee]

It’s such a good idea. Easier construction and it makes a void in the finished concrete the exact correct size! Genius

The site engineers all wore dirty overalls, boots and a hard hat, but we talked the same language! Once an engineer, always an engineer...:)

[@ReneSchickbauer]

I guess modern communication engineers see quite a low of sewer and pipeline construction. There's more and more usage of existing right-of-ways for things like fiberoptic cables. I've read of pipeline owners putting in fiber optics into their existing lines, using sewers to run internet and power lines. I've even seen a railway putting in internet lines, because it's cheaper than getting permission for a new right-of-way through a multitude of properties. And electricity networks are now putting in their own long-distance powerline communications to talk to smart meters, or even hang fiberoptics on powerline towers because they had spare poles. And, thanks to communications engineers ("magician" if you ever worked in HF applications), FM car radios work in long tunnels these days...

[@tomchidwick]

As a plumber for four decades, we have always struggled with the best way to seal subsurface pipe penetrations through concrete walls/foundations. I can’t count the number of different methods we’ve used. Most would eventually fail after years, but many right away due to hydrostatic pressure constantly trying to push the ground water through. There was never a penetration seal that you could bet your life on - until the invention of the LINK-SEAL. I have never had a failure of a LINK-SEAL, no matter how deep and how wet the ground was. It is extremely important to follow the installation instructions and to not be complacent in thinking you’ve done it before, so you are now an expert and can just install them by sight and feel. There are specific methods that must be followed. If you or your company is going to pay the cost (they are not cheap) of using a perfect product such as a LINK-SEAL, you need to treat it with respect.

[@jonathanlanglois2742]

It is interesting to see just how different construction techniques can be in different regions of North America. Since I'm in Canada, pipes need to be deep to prevent freezing, and at that depth, that often means digging through rock. Just about every contractor has a hydraulic hammer somewhere on site just in case when they dig. They don't bother with wet fill in my area. We've got so much rock that 0 - 3/4 it is the fill material of choice. Heck, in many cases, contractors have more rock than they know what to do with and end up recycling it on site with a crusher. They also don't bother with trench boxes most of the time. The preference is to just dig the excavation wider with angled walls.

I'm amazed that there's an entire company whose sole function is drilling holes (Holes of San Antonio Inc). They'd definitely know how many holes it takes to fill the Albert Hall. Grady, I'm*loving* this series.

Please keep this a regular series on your channel. Its absolutely fantastic.

[@MrMinusTwo]

This channel is literally the best. If Discovery channel made content this good I would still have cable

Qualified person to be the host. Excellent.

As a nuke gauge technician and concrete tester, I am so happy to see recognition in this series.

Grady, I appreciate and enjoy this series so much. While not a civil engineer or in the construction industry, I have been fascinated by utility systems- mostly wastewater systems since I was a kid. This series has been so much fun to watch and see it’s process. Thank you for taking the time and ambition to make the series a reality.

I hope you eventually get your own TV series or some kind of “officially” sponsored/sanctioned program. These pure, high production value, highly educational videos are straight up what some people need to become interested and involved in this field. Amazing work your doing!

"That process, and much, much more, on the next episode" I haven't been this anxious for the next episode to come out since watching DBZ as a kid!

I am fascinated by all the uses of the excavator - truly a Swiss army knife of construction.

never thought I would be so excited to watch a sewage station get built, but this is an instaclick. Please do more of this type of series, it is very informative!!!! I still remember going for a job interview to be a nuclear gauge tech, which you showed in the video with the yellow box. I had a severe flu and didn't make a good impression I guess, didn't get the job. Still haunts me to this day, I could be doing this stuff x.x

Thanks so much for this series, Grady. My 9-yr old daughter and I have been enjoying it a lot, I've been looking for accessible videos to explain construction for civil engineering and your channel is amazing. As a tunnel engineer, I really appreciate your approach from both the technical and construction sides! Looking forward to seeing more. Keep up the great work!

Awesome video glad we soil technician got represented testing the soil densities too. Really enjoying the series.

[@mrwalter1049]

This is hands down the best series I've seen this year.

[@justpaulo]

I love that you show the very important detail of the warning tape. Awesome job!

The fact that we can open the faucet and flush the toilet everyday is the true miracle of modern life. Thank you so much for you ingenuity and hard work.

[@Windiguana]

This is like this old house but for infrastructure! Absolutely amazing!

Amazing technological advances. Remote controlled vibrator -- what a relief to the bones and joints of the operator!
