I was lucky with the one slab that I had poured. The concreter told me what the minimum requirements were. We then agreed on extra reinforcing and caps and concrete. He understood that paying a little extra and avoiding problems later mattered more to me than cutting corners. Twenty years later it is still perfect.
Dude it’s suburban area 50 zone,he was at least doing that.True shit my cousins nephews girlfriends father has a second cousin removed said that could be the case,I have my doubts tho.
I did a steel inspection many years ago (no names!), and I had to go back 15 minutes later because I forgot my tape. When I drove up the driveway, I was confronted with most of the footing cages already out of the ground, and the crew pulling the last cage out of the ground. Needless to say, I chucked it in reverse and got out of there and reported it to my boss, the engineer. Investigation of other footings they'd done for the same builder showed that nearly all were missing cages. The builder went out of business and had huge lawsuits. Anyone in the game will know who I'm talking about.
Mainly just happens with driveways now. 4 sheets for 60 houses..but yes this is disgusting. joys of under quoting jobs then having to find money in it else where.
Blimey. I live in Wellington NZ, which has a propensity to shake, below and above the ground, from time to time. I heard of this exact thing, for offices built a few years ago. Essentially compliant steel was used for the inspection, and then the builder would swap out for non-compliant/ cheaper steel. Greed is a bitch aye. These very offices are now being converted into apartments.
I did owner builder on my place, I renovated the old section and done an extension on my house. It’s on stumps, the new section I was happy with what the engineer had put in, the old section was re-stumped, I added an extra 20 stumps and added on the perimeter extra where most old homes tend to sink. I’m very fussy even the builder I had do all the work laughed. But knock on wood it’s been over 5 years since I had built my place with 3 earthquakes we have experienced in Victoria, and my place hasn’t even had 1 crack or any movement or settling cracks. I’m a big believer the foundation is the most important part it’s carrying all the weight of the house. Great pick on the steel customer is very lucky you picked up on it.

Here in Tassie we structural engineers do the slab and framing inspections. I’m curious to know why you say that the building surveyor has done the inspection. Our surveyors are not qualified engineers.
@Site Inspections, Could you please clarify the lap length? On the video, time ~13m25s, I see that the overlaps are not on the same plane. To me it looks like one section on the slab is on a lower spot. As I understand it, lap length is the length of overlap that must happen so that the reinforcement works as a virtual continuous bar. And if not done, pullout is possible. So in the video, it wouldn't matter if there's no overlap because the bar is not the continuation of the other. Anyways, in my country, you'd have to bend the bar down and continue it along the other side by side for the lap length. The bend is sorta like a stretched Z.
You are right that there is a step in the ground levels across the internal beam. In large steps z bars are required to reinforce the neck. In small steps like this they are not and generally as long as the rib bars cross the trench mesh it is fine (the internal beam would act like a support so the rib won't be in tension, ie development length doesn't matter).
The external beam at the front of the garage was wider then spec cos the pod was cut too short, the other ones looked fine, also you can't put extra bars on the bottom rebate, you can't just float the bars in the air, and that form work is done after the steel is done.
Thank you so much for bringing these issues to the non professional and teaching us so much as you go throughout your inspection. I work in construction in the U.S and we've got similar issues as well. I wanted to ask you if this job passed inspection, how did the homeowner get the privilege to have you there and catch these mistakes before the pour? If I was having a house built in Australia and wasn't in the industry myself I would 1000% hire you to inspect every stage of the build. The amount of money spent on the total build is definitely worth hiring you to insure it is done properly. Keep doing what you do and I'm looking forward to the next video!! 😇😇😄

"Minimum standard not achieved" SO how much did the builder save? Not to worry, the owner won't know for a few years or until the warranty runs out! Is it any wonder the building industry is held in such low esteem.
Has nothing to do with saving the contractors just missed these items due to laziness not cause they trying to save money concreter make big profits they don't need to save its just extra work for them they decided not to do it or just missed it that's all
@@mp-pc1ky lazyness equals money saved. If you have to put in the extra work, how much does it cost to do it right?how much does it cost in materials, and labor? They will also try delay fixing it until another job in area comes up
Hi mate as an inspector are you required to inspect the termite protection. I cant see any signs of collars on penitrations of switch box, water and telecommunications as per AS 3630 marked on the engenering plans. It is clear that a part a has not been completed once the slab is poured Non Compliant
Where did those extra widths come from? Less styro or the slab being bigger than designed? In the former case, I don't really see the need---the styro would have way less tensile strength than the unreinforced concrete replacing it (assuming the bars are in the outer 30cm and the number of ribs stays the same). In the latter case, I'd be more concerned with the slab being bigger than designed.
I'm curious... What stops a rat or other burrowing animal from digging under the slab and then hollowing our the styrofoam blocks for a cozy burrow? And would that not weaken the section burrowed into, possibly causing a collapse of that area if the denning/burrowing covers a large enough area?
would be interesting what internal rib widths where if can make wider make edge beam less - I am more worried with these new 7 STAR BASIX foam slabs 85mm think and the designs
What are the requirements when I cut out a 1200x1200 section of the concreters' reinforcement because they smashed a sewer riser and continued to lay their work over the damaged pipe? Should they replace the internal rib or the sheet? I reckon they just leave it cut and sitting on top of the waffle pods as is.
I cannot wrap my head around the fact that a building surveyor can pass a non-compliant pre-slab installation. What’s the point in having these people if they just ignore all the breaches?
The point of ignoring problems and skimming over risks is to reduce "time to yes" as is it known in business. Whoever does the job the quickest wins, but it involves a hefty gamble that nothing will go wrong down the track.
@ Well, maybe it should be illegal for builders to choose their own inspectors. It should be written into every contract that the builder cannot choose their own inspectors are nor can they even suggest inspectors. The appointment of an inspector should be 100%, the choice of the person buying the home.
Aaaaaand this is why I built my own home.... yes it cost me the same in materials as it would have to contract people out to do the work but atleast it was done to above Minimum standards. If you have the time I would highly recommend licence yourself up and just build your home yourself. Sorry I tell a lie I contracted a company to install the Hvac unit and waterproofing... which i had to redo myself...
@intimatespearfisher brother is a sparkie with service providers ticket.. other brother is an industrial plumber... I'm a fitter machinist with restricted electrical so basically did everything....to a limit
Thanks site inspector i am a concreter thankfully we have good inspectors in the area i work golden triangle Victoria i tell the young guys to respect them i have learnt plenty from one old guy thanks mate
not a concreter, but im wondering; if the edge beams have been made wider than the plans, wouldn't that make the whole slab wider than the plans? and if that is the case, that would explain why the 600mm overlap of the n16 bar (splice) is far less that it should be, as the guys cutting the steel are measuring to the plans, not the now wider slab! is this right or am I off base totally?
Off base , the foam pods are a grid pattern and only start from a specific point The reason the beams are bigger is because you have to cut the box’s to fit in the spot because it’s not a full spot , they have just been cut ruffly The spots where he is picking , it js impossible to put 100-200 mm foam box in so it should have bars added to accommodate the widened beam Half of enginners don’t even bother It’s an addition if anything doesn’t weaken the slab by not doing it
I don’t think the assessment of the edge beam reinforcement was correct? I could see one bar on the top on the inside of the set down and then a couple at the bottom. At initial glance it seemed ok? What am I missing? The bigger issue for me is the location of the bars either top or bottom.
San Francisco's Millenium Tower is probably the most famous recent case of corner cutting in foundations. Last I'd heard they'd spent over a hundred million on a failed fix.
As an engineer, I wonder why we are being so precise in design stage and then handing over our work to these turkeys to destroy... Some of these people need to be held accountable
I was sent here by the algorithm and I know nothing on the subject. Can you explain What would be the potential consequences of non compliance? What can the home owner expect to go wrong by living in that house. Regulation exists for a reason and it is one thing to say "this is wrong" it is another to say "this is wrong and here is why"
That was really well done and informative mate. Scary to see how all these new builds are going to fair in 10-20 years. I bought a older house with good build quality because of watching your videos.
Great vids. Would love to hear about the possible consequences for each non compliance. E.g in this video if the measures aren’t correct, what could be the consequences. Internal wall cracks etc.
When you refer to the ‘building surveyor’ are you referring the certifier or engineer for the job? I’m in NSW and I’ve never had a certifer do a pre pour inspection ever!
Interesting the certifier pre pour should be one of the standard ones. It feels a bit pointless as the engineer has full discretion in the slab steel but hopefully they would catch unusual things, also they should confirm termite barriers and sewer pipes.
My Favorite man on RUclips, have you ever found a build that was perfect or had little or no defects and been impressed? no sarcasm in this question, just seems there is a serious issue with workmanship all over australia
just watched a inspection for 4 double story units next door, a inspector spent all of 15 minutes doing a visual inspection on all of them. drove off in a very expensive mercedes.
You have great and infor content as one that is going to have my house built. I live in the USA on the north east coast. I want to have my house built in the center of the house I want to have a wood burning fire place for my living room, dining room, kitchen and all 3 bedrooms. because of the power outages and thought about this. Would like to hear from anyone that deals with this type of build. With all the pros, and cons, of having a house built this way. Thank you kindly
When I was concreting all the the time majority of the inspectors wouldn’t even get out of their air conditioned $100k vehicles to even bother inspecting the slabs. At the same time there were some inspectors that would change the engineerings plans at inspection and then hold up the whole job to book a meeting with the engineer to talk about it and have new plans drawn up to the inspectors liking when the inspectors job was only to make sure the slab was compliant
Seriously please come to NSW for our framing inspection.. service and pride in workmanship has gone out the window on our build.. they genuinely don't care..
That was actually a pretty good setup in my opinion besides the overlap on the n16 bar....everything else was on point... Hats off to these fellow cementers 🤙
Did you watch the vid ? Out of compliance in a few keys areas. Get off the gear . Btw he needs to be there for the pour to stop them p*ssin it up out of spec
Hey mate, love the videos, if I can give some feedback, with your full house coverage videos, may I suggest restructuring your videos?.. you're obviously very knowledgeable, but for a non construction bloke watching, it seems like you're just jumping around to random places, one minute you've got the drone up looking at the roof, then you look at the frame, then somehow you're back to the guttering and roof, then frame again.. Maybe a video similar to this, where you show specifications for edge beams and maybe show where they run in the house etc. inspect what you can see with the frame room by room, then go onto roofing, wiring, etc. Similar to how I'd say you structure your reports, you'd have all faults with roof together, all faults with framing together, etc. Anyway, my two cents, interesting content that is just really scary to see what the building industry has become, keep doing what you're doing, hopefully one day builders will correct their ways.
@@neila9251 ahhh I see what you mean....thats just a fold in the poly, when it's poured it will be filled out....its not a raft slab so there's no dirt behind the poly to stop the magic from happening

Thankyou for all your work, I hope you are getting ready to teach the next generation, we need people like you to change this industry for the better
Can we get you on The Block?
I'd prefer to watch you then Dan any day
The Block builds are all cooked.
he'd have an aneurysm with the old house NON COMPLIANNNNCE
The block hasn't been worth watching for years. Just turned into another drama queen show.
@@Kwunt-l3q I’d like to watch it and learn more about the building process than seeing bullshit drama and people shopping for cushions while eating junk food.
"Minimum standard not achieved" SO how much did the builder save? Not to worry, the owner won't know for a few years or until the warranty runs out! Is it any wonder the building industry is held in such low esteem.
Has nothing to do with saving the contractors just missed these items due to laziness not cause they trying to save money concreter make big profits they don't need to save its just extra work for them they decided not to do it or just missed it that's all
@@mp-pc1ky lazyness equals money saved. If you have to put in the extra work, how much does it cost to do it right?how much does it cost in materials, and labor? They will also try delay fixing it until another job in area comes up
There is no end date to the liability of inadequate building. So long as the rules are followed then the warranty is time limited.
@@mp-pc1kyless steel means… less 💰 money spent
This is the first time your video started positive 3/3 on engineering so far. Keep watching
Hi mate as an inspector are you required to inspect the termite protection. I cant see any signs of collars on penitrations of switch box, water and telecommunications as per AS 3630 marked on the engenering plans. It is clear that a part a has not been completed once the slab is poured Non Compliant
Maybe that's out of his domain.
Love how educational this vid was ,,All simply explained so even a simpleton like me can understand ,,
Where did those extra widths come from? Less styro or the slab being bigger than designed? In the former case, I don't really see the need---the styro would have way less tensile strength than the unreinforced concrete replacing it (assuming the bars are in the outer 30cm and the number of ribs stays the same). In the latter case, I'd be more concerned with the slab being bigger than designed.
Gday I know you didn’t get to it in this clip, but the plumbing penetrations did they have collars installed on them? Especially for termite work.
I'm curious... What stops a rat or other burrowing animal from digging under the slab and then hollowing our the styrofoam blocks for a cozy burrow? And would that not weaken the section burrowed into, possibly causing a collapse of that area if the denning/burrowing covers a large enough area?
The blocks serve as void formers, meaning that you don't need anything in the space they occupy in order to maintain the integrity of the slab.
would be interesting what internal rib widths where
if can make wider make edge beam less
-
I am more worried with these new 7 STAR BASIX foam slabs 85mm think
and the designs
What are the requirements when I cut out a 1200x1200 section of the concreters' reinforcement because they smashed a sewer riser and continued to lay their work over the damaged pipe? Should they replace the internal rib or the sheet? I reckon they just leave it cut and sitting on top of the waffle pods as is.
Glad you found it before the concrete was poured 🙂
Thank you for educating people on the correct methods on doing work in the construction industry 👍
how many slabs in this country do you think are not to specifications? or rather, how many are?
I cannot wrap my head around the fact that a building surveyor can pass a non-compliant pre-slab installation. What’s the point in having these people if they just ignore all the breaches?
The point of ignoring problems and skimming over risks is to reduce "time to yes" as is it known in business. Whoever does the job the quickest wins, but it involves a hefty gamble that nothing will go wrong down the track.
@ Well, maybe it should be illegal for builders to choose their own inspectors. It should be written into every contract that the builder cannot choose their own inspectors are nor can they even suggest inspectors. The appointment of an inspector should be 100%, the choice of the person buying the home.
No other program is as ENTERTAINING as this! Nothing on television contains as much DRAMA as this!
Aaaaaand this is why I built my own home.... yes it cost me the same in materials as it would have to contract people out to do the work but atleast it was done to above Minimum standards. If you have the time I would highly recommend licence yourself up and just build your home yourself. Sorry I tell a lie I contracted a company to install the Hvac unit and waterproofing... which i had to redo myself...
How did you do the plumbing and electrical if you're not a licensed tradesman? Are you from the states?
@intimatespearfisher brother is a sparkie with service providers ticket.. other brother is an industrial plumber... I'm a fitter machinist with restricted electrical so basically did everything....to a limit
Thanks site inspector i am a concreter thankfully we have good inspectors in the area i work golden triangle Victoria i tell the young guys to respect them i have learnt plenty from one old guy thanks mate
not a concreter, but im wondering; if the edge beams have been made wider than the plans, wouldn't that make the whole slab wider than the plans? and if that is the case, that would explain why the 600mm overlap of the n16 bar (splice) is far less that it should be, as the guys cutting the steel are measuring to the plans, not the now wider slab! is this right or am I off base totally?
Off base , the foam pods are a grid pattern and only start from a specific point
The reason the beams are bigger is because you have to cut the box’s to fit in the spot because it’s not a full spot , they have just been cut ruffly
The spots where he is picking , it js impossible to put 100-200 mm foam box in so it should have bars added to accommodate the widened beam
Half of enginners don’t even bother
It’s an addition if anything doesn’t weaken the slab by not doing it
Where are the termite protection for the service penetrations? I dont see any collars or retic
Did the pour go ahead as is, or were the noncompliant issues rectified?
You are very knowledgeable and I thank you for these videos. Very informative! Thank you for the upload!
So beams are to wide… it is better to make them more narrow with the polystyrene and make them “compliant “ or pour in extra concrete?
What was the outcome? How did you resolve it with builder? Did they fix it and how?
No termite protection on the pipes / electrical?
KEEP UP THE GREAT WORK CHAMP!!💥💪👊💯
I don’t think the assessment of the edge beam reinforcement was correct? I could see one bar on the top on the inside of the set down and then a couple at the bottom. At initial glance it seemed ok? What am I missing? The bigger issue for me is the location of the bars either top or bottom.
A good foundation is essential to everything
It's
The
FOUNDATION!
It has to be done right.
Cutting corners is how Mascot Towers happened.
Unacceptable.
San Francisco's Millenium Tower is probably the most famous recent case of corner cutting in foundations. Last I'd heard they'd spent over a hundred million on a failed fix.
As an engineer, I wonder why we are being so precise in design stage and then handing over our work to these turkeys to destroy... Some of these people need to be held accountable
Best explanation ever.
I was sent here by the algorithm and I know nothing on the subject. Can you explain What would be the potential consequences of non compliance? What can the home owner expect to go wrong by living in that house. Regulation exists for a reason and it is one thing to say "this is wrong" it is another to say "this is wrong and here is why"
I love your strict to words process. My local government inspectors are useless.
So we see your videos on non compliant works… but I’m really interested …Have you ever inspected a build and found everything to be in order??
Doubt it 😂
Why there is so much foams blocks? Is it to safe the money on the concrete?
Definitely would not accept. Good work revealing these problems. Did the contractor fix the issues?
That was really well done and informative mate.
Scary to see how all these new builds are going to fair in 10-20 years.
I bought a older house with good build quality because of watching your videos.
Thanks for sharing
Great vids. Would love to hear about the possible consequences for each non compliance. E.g in this video if the measures aren’t correct, what could be the consequences. Internal wall cracks etc.
Good work like always mate!
When you refer to the ‘building surveyor’ are you referring the certifier or engineer for the job? I’m in NSW and I’ve never had a certifer do a pre pour inspection ever!
Interesting the certifier pre pour should be one of the standard ones. It feels a bit pointless as the engineer has full discretion in the slab steel but hopefully they would catch unusual things, also they should confirm termite barriers and sewer pipes.
Same here in Tassie. Structural engineers do the slab and framing inspections.
Hey mate, love your vids. What would be your advice as to ensure quality workmanship and to protect yourself?
Thank you educating us 🥇
Our pleasure!
Thanks for the rust and spray information. Really interesting and thanks for sharing the kwnoledge
What is the Styrofoam added for?
Is it for thermal insulation or for some other reason?
Did you check the piers first?
My Favorite man on RUclips, have you ever found a build that was perfect or had little or no defects and been impressed? no sarcasm in this question, just seems there is a serious issue with workmanship all over australia
Two bars for every 100mm top and bottom?
that's actually a pretty decent job
It is decent, but it’s incomplete and shouldn’t have been signed off yet 😊
just watched a inspection for 4 double story units next door, a inspector spent all of 15 minutes doing a visual inspection on all of them. drove off in a very expensive mercedes.
seeing people get stuff right for a lot of the vid is weirdly satisfying, make some videos about perfect jobs done sometimes :)
How did the formwork measure up?
You have great and infor content as one that is going to have my house built. I live in the USA on the north east coast. I want to have my house built in the center of the house I want to have a wood burning fire place for my living room, dining room, kitchen and all 3 bedrooms. because of the power outages and thought about this. Would like to hear from anyone that deals with this type of build. With all the pros, and cons, of having a house built this way. Thank you kindly
When I was concreting all the the time majority of the inspectors wouldn’t even get out of their air conditioned $100k vehicles to even bother inspecting the slabs.
At the same time there were some inspectors that would change the engineerings plans at inspection and then hold up the whole job to book a meeting with the engineer to talk about it and have new plans drawn up to the inspectors liking when the inspectors job was only to make sure the slab was compliant
Seriously please come to NSW for our framing inspection.. service and pride in workmanship has gone out the window on our build.. they genuinely don't care..
I love it when you say "Non Compliant" lol
That was actually a pretty good setup in my opinion besides the overlap on the n16 bar....everything else was on point...
Hats off to these fellow cementers 🤙
Did you watch the vid ? Out of compliance in a few keys areas. Get off the gear . Btw he needs to be there for the pour to stop them p*ssin it up out of spec
😂😂😂
@@tim.fletcherwhy are you laughing? He said the truth
I agree. Wondering if they relying on inspection to correct any issues.
@@edwardhewer8530 I rekon they knew old mate was coming haha
BEAUTIFUL!
Hey mate, love the videos, if I can give some feedback, with your full house coverage videos, may I suggest restructuring your videos?.. you're obviously very knowledgeable, but for a non construction bloke watching, it seems like you're just jumping around to random places, one minute you've got the drone up looking at the roof, then you look at the frame, then somehow you're back to the guttering and roof, then frame again..
Maybe a video similar to this, where you show specifications for edge beams and maybe show where they run in the house etc. inspect what you can see with the frame room by room, then go onto roofing, wiring, etc.
Similar to how I'd say you structure your reports, you'd have all faults with roof together, all faults with framing together, etc.
Anyway, my two cents, interesting content that is just really scary to see what the building industry has become, keep doing what you're doing, hopefully one day builders will correct their ways.
You are a legend bro! 👊🏽
What happens now? Do you contact the builder on behalf of the owner? Or does the owner have to call them up and let them no whats going on?
Definitely extra steel in the external beams that are required but the 600mm minimum overlap and the paint on the steel lol wow! let it go
Is it actually "paint" they used? as a kid I spray painted polystyrene and it completely melted . Wondering whether they used a food dye or something
Acetone would absolutely destroy it also.
How is polystyrene acceptable for a slab? It just makes the whole lot thinner but let's it move?
The cover on some of the steel in the edge beam seemed minimal or non existent 7:04?
There is about 60mm of cover there, that's heaps lol
@@torchup9256 Looks like the plastic is touching the steel to me
@@neila9251 ahhh I see what you mean....thats just a fold in the poly, when it's poured it will be filled out....its not a raft slab so there's no dirt behind the poly to stop the magic from happening
I used to do resi slab inspections, and boy, did the concreters come up with every excuse under the sun for little things I picked up. Missing re-entry steel, short on laps, completely no steel in areas, waterproof membrane missing or torn up or not taped up properly. Failed so many slab inspections lol
