That's a job that takes skill, very hot and hard work. I finish my benching with 25-50mm of cement/block sand mix over rough concrete inside a precast riser with base which is all they allow here.
Missing a few things here, gotta have stone (about 6" or so of #57 stone) under the concrete, and there's no rebar. This is to keep things from shifting in the future and causing the base to crack from any ground movement/vibrations, settling, uneven curing... ect. Especially if this thing is anywhere near traffic.
The strength has nothing to with the future. The ground water will eventually get thru the concrete for one the stone helps drainage the rebar or wire is your strength plus your first barrell is gonna need a concrete collar to help support the barrel an for seal the barrel to the pile of concrete lot of concrete actually per what a manhole cost somebody putting lots of $$$$ in there pockets. Hee hah hee hah 😆
@@chriscolwell2963 you don’t need rebar for this because the Geotechnical engineer would probably do soil tests etc and a lot of these manhole systems have 0 rebar in them because the concrete is high pressure- or even sometimes precast. So explain to me how precast wouldn’t break? Exactly
This is one way, not the way. You can place the channels using clay or plastic pipe and bed them in concrete and build the concrete up to the level in the area where the rings will rest 'only' and make sure its level. Then you site the rings on this and go back in to bench the manhole with a grano mix. This was very messy.
In this case we had to fallow the irvine caltrans spec. Also one of the gentleman up top is the inspector and you already know that if it's not per standard you will take it out and start all over
Brendan stone means... You should have a 2 or 3 foot manhole riser, set it on bricks then pour the concrete and if you want you can even cut windows on the riser for where the pipes come in and drop it in for a nicer job and less concrete.. very easy!
Well in different states different laws in construction, most inspector here in California don't want to change, they go by the book, some of them don't even have actual field experience

Here no rebar but concrete mix is 560 c 4450 high strength

@@chriscolwell2963 it’ll be ight
different zones different specs as long as its to the plans.

Doing this helps a lot I worked for municipality and so many man holes looked bad
Why aren't they using precast? Cheaper to make your own? Definitely good work though checking fall and level by eye.
They work with pipes and diggs and heavy machinery and inginerie that constantly change things

Yes but this is the way the spec. Is calling for

Specs not like that in 🇺🇸 🇺🇸 unless private
I am starting this kind of work soon as apprentice! Any advice or tips? Thanks!
Looks like Pima county manhole. They should up grade to fiberglass impression rings
pablo molina, upgrade? that’s all I’ve ever done the last 15 years was impression rings.
It's in california
@@franciscomontenegro2170 where can i get impression ring for 48 inch manhole
This is in Irvine California
Theres no way our inspectors are gonna let us carve our trofff😊
beautiful finish
Anyone know this guy?
Its by fmpipeline co.
Sure do know that guy. He’s my super and who trained me.
wouldn't you normally have the manhole in place before forming the base
Brendan Stone that’s is the manhoe he is making it
Tru Blu true you are right

No
Hahaha,no 😂
wheres the work at?
Irvine ca.
Why don’t you use styrofoam like we use to do bases in OZ
Well in different states different laws in construction, most inspector here in California don't want to change, they go by the book, some of them don't even have actual field experience
nice work. i know what it takes to pour those bases. manhole builders rule.
andrew silvas this guy is is professional
Far too wet and far too long 5 a day forming with semidry
3% slump in concret not a 6 or7 u would use on a sidewalk
why arent the pipes plugged
Wen a professional is doing it there is no need for covers
@@franciscomontenegro2170 🤣🤣👌
Plugs are inside about 6 "
