Precast concrete vs In-situ concrete Who Wins?

[@Karozz]

Got my construction exam tomorrow. Your content is so helpful!

[@BrendanHasty]

hope it went well

[@Karozz]

@@BrendanHasty You might be the main reason I got a good grade. Might tune in from time to time, haha. Love from Denmark

Opal Tower failure was just at the joints between two precast wall panels where insufficient grouting and detailing had caused the structural splitting damage.

I teach concrete design at University (in Architecture, not Civil Engineering), and, while this in situ/precast debate comes from time to time, however, the most trendy debate among students nowadays is to completely get rid of concrete at all because of sustainability reasons. Most questions I get from students regarding choices during the structure conception phase are related to how to avoid using concrete at all. I'm telling you this because I truly believe the cause is that concrete-related companies and businesses didn't do their homework of properly showing to the public that concrete can be more sustainable than other options. At the University we can do very little to counteract this craziness, when the "concrete is not sustainable" motto is the trend everywhere.

imagine if the students actually questioned the climate agenda BS. then they'd be really thinking. IF ONLY we had educators who also used their brains..

[@mattshelton279]

Hi there..As the owner of Benzini Precast Concrete, I can perhaps chime in here. Concrete is part of the "Stone" / masonry constructions elements (Such as timber, steel) my question to anyone who is questioning the sustainability of of concrete is.." Have you ever been to Rome? Egypt? London? I ask this question because the only buildings and or monuments that are still around today from 500 or 2000 years ago are concrete and or stone or reconstituted stone (concrete) . 98.5% of timber buildings cant last longer than 100 years. So the question then becomes... At what end of the candle are you measuring sustainability? Imagine if every road or freeway was made out of timber!! well guess what .. it used to be, but we upgraded to a more "long lasting" "sustainable" solution 100 years ago .. concrete.!!!!The same shit thats been around for 3000+ years!!!~ Its about as sustainable as you will ever get.

[@tealkerberus748]

Ask them to do the maths .. how much plantation timber would it take to replace the world's concrete consumption, and how many planets would we need to grow that timber? Or how much steel would it take, and what would the climate impact be? Concrete's CO2 impact is because we use so much of it. The solution is not to replace the concrete with something else, because all the alternatives are worse. The only way to fix this is to build less. Architecture students are in a great position to push for building less. The easiest way is to change our time spans. Instead of building a 50 year house, build a 500 year house - that's an instant 90% reduction in annualised embodied carbon.

Thanks for sharing your knowledge, love the easy way you explain each topic. I have been watching your videos and of course I subscribed to your channel

[@BrendanHasty]

Thanks for you support Maria, also thanks for noticing. Where possible I try and breakdown what can be complex topics into in easy in understand explanations.

[@rayahnraschke405]

Hi Brendan, just found your channel and as a recently graduated civil engineering student in Aus, I'm finding your videos super helpful. I was just wondering if you could offer any advice on how best to improve my resume to be more appealing for structural engineering roles. Such as developing software skills like autoCAD and Revitt, or studying structural design textbooks.

[@BrendanHasty]

Hi Rayahn, if you are just starting to look for your first jobin engineering Apply to all size of compains and taylor your resume for the compain. starting at a small firm gets you in the door, from there it becomes easier. I will likely do a future video on this

[@DeepakKrishna11]

Hi Brenden, good precise video. Keep up the good work.

[@BrendanHasty]

Hi Deepak, Glad that your enjoyed it and your ongoing support.

[@alongsunsets6334]

Hello Brendan! I am working on my thesis and i would like to know what is your opinion on the best suited for foundation in protected areas such as mangrove areas? Thanks!

[@danahawkeye]

Can both methods be used together on the same building?

[@ifiwantyoutofeel]

Can you explain the Miami's condo collapse 🤔 how could that happen ?

[@BrendanHasty]

Hi Daniel, I am just about to post a video on that so stay tuned.

[@yekutielbenheshel354]

Excellent!

[@BrendanHasty]

Thank you! Cheers!

[@shenoyglobal]

for a terrace application we want to use precast slab to minimize cracking can you let me know if there are water proofing additivies to add during pouring the precast so we have a inbuilt waterproofing system

[@thesage1096]

thank you for your insights

[@BrendanHasty]

Hi Sage, Welcome back. glad that you found the video insighful,

[@plutus205]

Which is cheaper for building a single story house?

[@BrendanHasty]

Hi Plutus timber framing would be the cheapest.

[@InigoMontoyaFA]

How far away can precast concrete walls be shipped? Does shipping cost materially factor into the cost calculation vs. in-situ?

[@BrendanHasty]

Hi Clark, shipped transportation does come into the cost greatly typically I'm areas far away from precast yards are insitu as it is much more efficent to transport concrete in a liquid or un mixed state.

[@TonioCartonio619]

Hello Brendan, amazing video as usual. I was wondering if you will ever make a video about great infrastructures such as the Millau Viaduct. It is just a suggestion but I think your take on the topic would be a must-watch.

[@BrendanHasty]

Hi Tonio, thanks for your support. It is an amazing Bridge just need to find enough Broll to show off this engineering masterpiece.

[@TonioCartonio619]

@@BrendanHasty Thanks for the answer, have a nice day :)

[@ghostpeppered4524]

Could probably find optimizations if you could make the factory mobile to fabricate modules with in-situ concrete. ie. if the factory could fit inside a series of shipping containers, you could stay busy since the mobile factory would have 4 walls and a roof to protect from bad weather.

[@BrendanHasty]

Hi Ghost storage of the green precast panels needs considerations, it would save on transport but at the cost of space.

A canopy on wheels which can be shifted over the tables is all that's required

👌

[@BrendanHasty]

Hi Kimmy, thanks for watching

[@BryceFryar_Private]

Brendan just caught this presentation on Precast by Engineers Australia. Highly recommend. Oh and nice work with another great video kzbin.info/www/bejne/baG9qJVqqJp4sNU

[@BrendanHasty]

Hi Bryce, thanks for the suggestion. I will check it out. Glad that you enjoyed the video, any suggestions on other topics to cover?

[@kevpatguiriot]

PRECAST VS STEEL 🤔🤔

[@BrendanHasty]

Thanks for the suggestion would be a great video

[@Nameless3567]

With statement "There is a con in the name" you lost your neutrality 😂

[@lightning9279]

Thumbs down with that carbon crap. It's a scam. 👎 Always has been.

why looking so sad cloosing your eyes always unormall
