Mate I'm a Vic registered building surveyor and this is all stuff that I am seeing and finding every single day! Read the table on the engineering and install it accordingly! Thank you so much for bringing out a reinforcement gauge! I have been hunting the internet for ages trying to find one because there used to be those poly wheels that the reinforcement companies used to provide but I can't find them anywhere! I just bought one of yours!
@@TheJiminiflix early on mate when they were coming out at 75mm thick or so I am pretty sure that there was multiple stories of people jacking cars up in garages and the jack punching through the slab. I personally haven't heard of any failures since unless the slab was poured with incorrect cover to the reinforcement and the thickness wasn't right as well.
@@malleedirtbikerider ive heard of people putting jacks thru the slab in a garage situation, but never in the main dwelling. That was early days but. I told my boss and for years we insisted on doing the garage as raft, eventually to the waffle again, but using 100mm slab instead of the 85.
@@mhombi yeah mate I meant in the garage obviously. 🤣 Bit hard to jack a car up in the middle of a house. Since they went to 100mm there hasn't been the problems
@@malleedirtbikerider sorry mate, i did mean in the garage, but more meant never heard of problems in the main part of the house. still alot or the bulk builders insisting on 85 in that garage too but. as long as someone signs off in the end and its still to code? i am talking class m stuff but. obviously this slab is more a h or something with the extra reo in the edgebeams
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.
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.

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 all you do. I have a problem with concreters leaving and letting the polistiren offcuts blowing away when we get a strong wind, thay should be made to clean up the mess.
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
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.
I thought your tool was a bit useless until around 5.50 when you mentioned take a photo. I have to prove my work procedures with photos and it would actually be really good for that
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..
My Favorite man on TH-cam, 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
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
The reinforcement as placed should comply with the structural engineers drawings. The number of bar chairs should be increased to comply with the requirements of the structural Engineering drawings. The design engineer must insist that the site foreman gets the reinforcement contractors to rectify all of the faults BEFORE any further work proceeds.
The bar chairs have good placement (I've never actually seen that style before) if they chair up close to the corners they risk breaking pods during the pour. This is where judgement is more important then following a standard that would have never considered a situation like this.
@@av135 Agreed, so long as there are sufficient chairs to support the mat that is all that is important. I've done prepour inspections on many big infrastructure projects in Perth. Engineers should just note "sufficient chairs and wire ties to hold the reinforcement in place". Walking around on the mat might find a few spots where the ties are loose or the bars sag too much, add another chair and a few more ties. Stopping a pour because chair spacings are noted when inspection finds the chairs adequate is just wasting time and money.
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
Back in the old days. The footings where 400mm X 250mm into natural or pins into natural ground and cross beams. With 150mm thick slab on top. 92 mesh, 16mm bar. Earth is like a sponge and when it dries out a house will sink and crack.
Weird setup this one, we sometimes do 300-900mm deep strip footing and then setup the slab on top of that. Concrete could end up 1.2m deep in some cases.
@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 good thing about the Australian Standards is that there can be alternative ways to be compliant. They are not rigid. But.... If you want to deviate away from the Standard, it basically has to be engineered to be a better solution that the one the Standard mentions.
I really enjoy yours vids mate but that’s a fair dinkum nitpick it’s like your after brownie points just to find problems it’s petty and that Concretor has done a great job.Seriously mass concrete around edges on a raft slab with 3 bar trench mesh is far better than an extra bar like I said I enjoy and appreciate your content but that’s a carve up 👍
Some simping bullshit. It is not a complete job. It is an approximate job on the foundation for what is likely the single largest purchase a person will ever make. It would be like leaving bolts out of a car. The engineering standards are there for damn good reasons lest we end up with more things like Mascot Towers. It frankly says far more about your sloppy standards that you think that was just nitpicking. The paint is nitpicking, missing half the reo in one trench is a failboat launch.
It isn't nitpick though, those are the BARE MINIMUM standards, if they can't even hit the bare minimum standards, then it is a problem. The sht should be over engineered to be quality anyway, should not have issues meeting absolute minimum standards.
Had a friend who had 11 truck and trailer loads of shingle placed (up to 900mm thick) where this build has polystyrene blocks. The main room was 15 metres by 6 metres with the rest of the single storey 3 bedroom house to match. Along came the 6.8 earthquake plus subsequent 24,000 smaller quakes and hey presto... not a crack in the slab Except for 8 metres of cracks between a couple of sheets of gib on the ceiling the house was undamaged....
(I am not a builder) But since the big 2011 Earthquake here in Christchurch, New Zealand, s very similar looking foundation method has become very popular for many new residential constructions of 1 to 3 storeys. (Obviously complying with modern EQ and insulation codes). Similar to what is shown on this video except the polystyrene foam blocks here, are closer to 600mm tall. Perhaps because in our colder climate, it plays a greater part in insulation.
For every slab that gets ‘inspected’ and flagged for defects, there are 1,000 that get ‘inspected’ and passed that are defective but no one will ever know under the concrete until it cracks or fails. I’ve seen it too many times. Even when the concreter REMOVES steel after the inspection is done but before the pour. Buyers beware !! 😎
This slab is amazing compared to a lot of the rubbish being poured in SEQ. It seems like something is off in the drafting or design. I can see why 200mm foam would create problems during pour. I would accept if engineer signed off on a performance solution. But just installing the required steel in the first place would be half the cost of reengineering a departure.
Thankyou for exposing the critical laziness and pathetic drive-by decisions made by a few of these incompetent building surveyors, I’m amazed they get away with such tactics to approve these sites! and then to also get away with it financially. It’s such a shame similar works are then followed by some of the lesser caring builders, that don’t care or know regulations, to only join these short cut approvals!. All home contracts these days should now get a double stamp approval (site inspections guy) before each stage to prevent poor buyers from these rip off firms. People complain about house prices, well if you haven’t built before, try it one day, then offer your dilemma you may of encountered. It becomes a financial nightmare.
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
Being a retired Engineer, I too had "MIN Requirements" that everyone wanted to ignore, and when YOU ignore want the Engineers wanted, bad things happen..Ever hear of the Space Shuttle Blowing up??
IMO not a good example. The shuttle was a bad engineering decision. Mascot Towers or the Hyatt Regency Walkway in Kansas City are good examples of when a contractor CBF following the Engineers drawings and ad libs or cuts corners.
@@stuartlaird7341 The engineers that designed the solid rocket boosters said DO NOT LAUNCH in freezing temperatures...They did and it went boom. The bottom line is, we will Design it, YOU build it according to OUR design, and nobody gets hurt
Reading drawings is key. If you are not familiar with reading concrete drawings, the symbols and abbreviations are not obvious. The Concretor and building certifier should know however.
Australia has such robust laws and standards in place, and 'experts' who sign off on the work to ensure quality.. one wouldn't expect such cowboy construction in this country! You have single-handedly exposed Australia as the wild west of construction work. What kind of future is Australia building with such low standards! Thank you for your excellent work!
Wait... so they made the edge beams and the internal beams wider than planned? But wouldn't then the slab be wider? Not only costing the builder more concrete but also in the end the building isn't according to spec and probably violating the build permit?!? I mean, 1x internal beam 30cm + 2x edge beams 10cm wider than planned => Building is HALF A METER wider?!?!? Is that something that happens often?
@@RiffRaffMama. thanks, that explains it. I still think the builder hurts himself since the poly probably works have been cheaper than concrete. And also I doubt a bit more concrete without additional steel will have any impact on the performance since the required amount of steel is still in. So it should be solid enough.
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.
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?
If the edge beam only needs to be 300mm but the form is a bit bigger so more concrete is used unnecessarily the extra reo is not needed, as the concrete beam size exceeds requirements.
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"
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'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.
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.
Best explanation ever.
Thanks for the rust and spray information. Really interesting and thanks for sharing the kwnoledge
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
You are a legend bro! 👊🏽
that's actually a pretty decent job
It is decent, but it’s incomplete and shouldn’t have been signed off yet 😊
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
I love your strict to words process. My local government inspectors are useless.
No other program is as ENTERTAINING as this! Nothing on television contains as much DRAMA as this!
Thanks for all you do. I have a problem with concreters leaving and letting the polistiren offcuts blowing away when we get a strong wind, thay should be made to clean up the mess.
I love this bloke, never lets anything slide.
Definitely would not accept. Good work revealing these problems. Did the contractor fix the issues?
You are the man!!
BEAUTIFUL!
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
Hey mate, love your vids. What would be your advice as to ensure quality workmanship and to protect yourself?
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.
I thought your tool was a bit useless until around 5.50 when you mentioned take a photo. I have to prove my work procedures with photos and it would actually be really good for that
The slabs and walls in structures are like cheap Styrofoam beer coolers.
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
My Favorite man on TH-cam, 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
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
Lovin the youtube banner !
The reinforcement as placed should comply with the structural engineers drawings. The number of bar chairs should be increased to comply with the requirements of the structural Engineering drawings. The design engineer must insist that the site foreman gets the reinforcement contractors to rectify all of the faults BEFORE any further work proceeds.
The bar chairs have good placement (I've never actually seen that style before) if they chair up close to the corners they risk breaking pods during the pour. This is where judgement is more important then following a standard that would have never considered a situation like this.
@@av135 Agreed, so long as there are sufficient chairs to support the mat that is all that is important. I've done prepour inspections on many big infrastructure projects in Perth. Engineers should just note "sufficient chairs and wire ties to hold the reinforcement in place". Walking around on the mat might find a few spots where the ties are loose or the bars sag too much, add another chair and a few more ties. Stopping a pour because chair spacings are noted when inspection finds the chairs adequate is just wasting time and money.
Pour effort.
On the edge beams, 2/3 L11TM why are they tied together? Why not one for base and one midway?
Easy fix. The 600mm meeting points just add a longer 2m bar, to correct. No need to rip up works. Feed bars in.
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
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
Back in the old days. The footings where 400mm X 250mm into natural or pins into natural ground and cross beams. With 150mm thick slab on top. 92 mesh, 16mm bar. Earth is like a sponge and when it dries out a house will sink and crack.
Weird setup this one, we sometimes do 300-900mm deep strip footing and then setup the slab on top of that. Concrete could end up 1.2m deep in some cases.
Thats what the steel reinforced beams in the concrete do. Provide stiffness under tension over sunk earth so nothing cracks. Like a bridge
@@superwag634 You should comment if you don't know.
@@adrianbates5056 I’m an engineer. Been one since 2001 so I’ve seen more screwups than most people 🤷♂️
@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 good thing about the Australian Standards is that there can be alternative ways to be compliant. They are not rigid.
But.... If you want to deviate away from the Standard, it basically has to be engineered to be a better solution that the one the Standard mentions.
I really enjoy yours vids mate but that’s a fair dinkum nitpick it’s like your after brownie points just to find problems it’s petty and that Concretor has done a great job.Seriously mass concrete around edges on a raft slab with 3 bar trench mesh is far better than an extra bar like I said I enjoy and appreciate your content but that’s a carve up 👍
Correct. Id like to see this guy come any where near close to getting a found prep this nice pen pusher no practical skill ar all
Inspectors always pick something no matter how small, gotta make the client feel that the $$$ spent is justified..
Some simping bullshit.
It is not a complete job. It is an approximate job on the foundation for what is likely the single largest purchase a person will ever make.
It would be like leaving bolts out of a car.
The engineering standards are there for damn good reasons lest we end up with more things like Mascot Towers.
It frankly says far more about your sloppy standards that you think that was just nitpicking. The paint is nitpicking, missing half the reo in one trench is a failboat launch.
It isn't nitpick though, those are the BARE MINIMUM standards, if they can't even hit the bare minimum standards, then it is a problem. The sht should be over engineered to be quality anyway, should not have issues meeting absolute minimum standards.
@PlanInMotionthey want call backs. Good coin In it
Some of that reo looked close to the formwork. Hope they achieved coverage. 👍
Had a friend who had 11 truck and trailer loads of shingle placed (up to 900mm thick) where this build has polystyrene blocks.
The main room was 15 metres by 6 metres with the rest of the single storey 3 bedroom house to match.
Along came the 6.8 earthquake plus subsequent 24,000 smaller quakes
and hey presto...
not a crack in the slab
Except for 8 metres of cracks between a couple of sheets of gib on the ceiling the house was undamaged....
(I am not a builder) But since the big 2011 Earthquake here in Christchurch, New Zealand, s very similar looking foundation method has become very popular for many new residential constructions of 1 to 3 storeys. (Obviously complying with modern EQ and insulation codes). Similar to what is shown on this video except the polystyrene foam blocks here, are closer to 600mm tall. Perhaps because in our colder climate, it plays a greater part in insulation.
how many slabs in this country do you think are not to specifications? or rather, how many are?
What was the outcome? How did you resolve it with builder? Did they fix it and how?
Started off so strong! Nek minnit non compliant. I did appreciate the fact you said “excellent work”at one stage. A rarity nonetheless
For every slab that gets ‘inspected’ and flagged for defects, there are 1,000 that get ‘inspected’ and passed that are defective but no one will ever know under the concrete until it cracks or fails.
I’ve seen it too many times.
Even when the concreter REMOVES steel after the inspection is done but before the pour.
Buyers beware !! 😎
the video went on for so long I thought i would never hear my favourite words, "non-compliant"
Hi from nz, there is way more steel in this than a slab in nz, 6 mm mesh is standard. thanks for the video
This slab is amazing compared to a lot of the rubbish being poured in SEQ.
It seems like something is off in the drafting or design. I can see why 200mm foam would create problems during pour.
I would accept if engineer signed off on a performance solution. But just installing the required steel in the first place would be half the cost of reengineering a departure.
That fancy tool you have wasn’t big enough to measure my tool when it’s barred up unfortunately 😂
Thankyou for exposing the critical laziness and pathetic drive-by decisions made by a few of these incompetent building surveyors, I’m amazed they get away with such tactics to approve these sites! and then to also get away with it financially. It’s such a shame similar works are then followed by some of the lesser caring builders, that don’t care or know regulations, to only join these short cut approvals!.
All home contracts these days should now get a double stamp approval (site inspections guy) before each stage to prevent poor buyers from these rip off firms.
People complain about house prices, well if you haven’t built before, try it one day, then offer your dilemma you may of encountered. It becomes a financial nightmare.
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
Being a retired Engineer, I too had "MIN Requirements" that everyone wanted to ignore, and when YOU ignore want the Engineers wanted, bad things happen..Ever hear of the Space Shuttle Blowing up??
IMO not a good example. The shuttle was a bad engineering decision.
Mascot Towers or the Hyatt Regency Walkway in Kansas City are good examples of when a contractor CBF following the Engineers drawings and ad libs or cuts corners.
@@stuartlaird7341 The engineers that designed the solid rocket boosters said DO NOT LAUNCH in freezing temperatures...They did and it went boom. The bottom line is, we will Design it, YOU build it according to OUR design, and nobody gets hurt
Reading drawings is key.
If you are not familiar with reading concrete drawings, the symbols and abbreviations are not obvious.
The Concretor and building certifier should know however.
GDay - Like you have mentioned in all your videos, we want the ALL the MINIMUM specs satisfied...
Rusty Concrete mesh ( surface rust) is actually better than gal coated mesh or clean mesh. the concrete binds to minor surface rust better.
Australia has such robust laws and standards in place, and 'experts' who sign off on the work to ensure quality..
one wouldn't expect such cowboy construction in this country!
You have single-handedly exposed Australia as the wild west of construction work. What kind of future is Australia building with such low standards! Thank you for your excellent work!
Wait... so they made the edge beams and the internal beams wider than planned? But wouldn't then the slab be wider? Not only costing the builder more concrete but also in the end the building isn't according to spec and probably violating the build permit?!?
I mean, 1x internal beam 30cm + 2x edge beams 10cm wider than planned => Building is HALF A METER wider?!?!?
Is that something that happens often?
No, the slab isn't wider, just the poly pods are not spaced properly/there's not enough of them to fill the centre of the slab correctly.
@@RiffRaffMama. thanks, that explains it.
I still think the builder hurts himself since the poly probably works have been cheaper than concrete. And also I doubt a bit more concrete without additional steel will have any impact on the performance since the required amount of steel is still in. So it should be solid enough.
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.
Did the pour go ahead as is, or were the noncompliant issues rectified?
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?
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.
If the edge beam only needs to be 300mm but the form is a bit bigger so more concrete is used unnecessarily the extra reo is not needed, as the concrete beam size exceeds requirements.
this used to happen 50 - 60 years ago. $500 for the engineer/inspector to turn a blind eye & rubber stamp an entire book of these 'fit to pour' slabs.
Good work man! Love your details.
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"
Did I just watch a 15 minute ad for a tool I'll never need. Yes I did 😂
That’s absolutely non compliant Habib
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.
Did they fix the problems
