Honnestly, the main problem is that saving resources takes time to optimize structures. And when your employer gives you two weeks, you have two weeks. I would love to engineer better, more durable stuff. But durable is not profitable, and better is costlier. Shitty designs are rarely made by choice sadly.

Agreed, I'm a structural engineer and I've 0 time to even consider better design/better alternatives. To even get projects your company eats into your salary to push out lower costs. That means your company spreads out thin to even survive and each engineer can be handling 3 projects at once. We do not have time at all. I can only say that at most we can optimise 70% of our design and senior engineers are around 90%. Green concrete are frowned upon as it doesn't increase profits. Cheapest green concrete are at least 25% costlier and usually their mechanical performance falls short of standard OPC. At the end of the day it's time and money. Unless the government can help us by forcing developers to give us more time and money. No engineers will practice these. The only call to action is literally us quitting and having no structural engineers left. In Singapore (where I practice), we are already seeing a shortage of structural engineers. This is a sunset industry.

Good & informative video. Thanks Brendan for sharing such kind of informative videos.👍🏻

What is your opinion on structural optimization techniques? It is used extensively in the automotive and aerospace industries. How popular is it in structural engineering?

Hi the Professor, Structural optimisation is something that is coming to structural engineering but is something new and for the more technical engineers from my experience. Also what seems to work best it needs a combination of a smart agents/logic paired with genic algorithm or AI. It you dont have a smart agents to goes down some weird paths.

Hi Brendan, can you suggest some recently used concrete optimization techniques or in terms of analysis, reference materials/papers about performance based design in structural engineering?

Architecture and engineering are an amazing thing. Shouldnt be separated in any way, and share the responsability of the project itself. Architects must have enough knowledge to not just pass a idea/concept and expect a magic practical solution fron the engineer, unless exist an agreement on that. Remember: firmitas, utilitas, venustas. Add character and must consider economy of means. Use the simplest and most cost-effective strategies, a frugal approach to the design and construction process, using materials in a way that is true to their nature. Design multi-functional spaces, reducing building size and complexity. Minimalism, "less is more". Avoid "Pompous and conspicuous" architecture.

Nuclear technology and safety have improved. That is exactly what the promoters want you to talk about. That discussion is a distraction, and if you only had limited time like these comment postings and you spoke on their topic, YOU WILL LOSE. They go from the maco (no CO2 emissions) to the micro look at the energy in this 1 kg uranium metal. Millions and millions and millions and millions and millions of customers need clean energy. And the nuclear GRID electricity energy would have to go out to 100% supply. 7 times bigger. 7 times nothing is not very big. 7 times the national electrical GRID is insanely expensive. Nuclear just wants to monopolise the existing national grid. With government disaster insurance and Government guaranteed cash flows. Bill Gates and Rupert Murdoch Skynews and LNP are strongly promoting nuclear electricity. Bill Gates monopolised software. Rupert Murdoch is paying $3 billion. LNP, the Australian political party's, Snowy 2.0 pumped hydro expansion project budget is exploding from $2b to $15b and years longer. French submarines contract cancelled at $billion??? Now 6 USA nuclear submarines. Uranium yellowcake exports will explode to pay for no coal exports. My point is that nuclear promoters talk about new grid costs to renewable energy and ignore their own grid limitations while promoting the sunniest continent in the world to go nuclear. And refer to EVs and Utility Factors and new grid costs and monopolising existing national grid. This is an engineering problem, and we need more engineers to analyse and speak up. Maybe you have to be a Construction Engineer to understand. Thank you for giving me a forum to speak up. You may be limited by your employers on this topic as $millions will flow to engineers by nuclear solution. Labor is pushing grid renewable energy, and it has the same problem as the opposition is pointing out. The new grid costs. Only engineers are experienced and qualified to speak up. Community batteries are an excellent start. 30 homes in my street can generate 1 mWh. Daily. Hornsdale BIG BATTERY is 200mWh. So 70 streets but as the sun does shine daily, then 200 or 400 streets can benefit. And no new grid construction. As selfplug-in V2G EVs come onto the market the community battery can be relocated to slower EV adopting suburbs. Rooftop solar PV is cheaper than windows $/m2. Nobody does the maths.

Great insights for engineers and the role we should have in society. The average person sees engineers as a last resort in construction industry for when problems arise. The government should also let engineers do they job and stop intervening how we should conduct our work. There's a slogan I shared with students " Civil engineers helps civilized civilization" Malik

Agree performance based design is often over looked, the biggest issue is the time required to design so fees need to increase but you will save money in the end

Good insights.

Architect / Engineer venustas / utilitas / firmitas Character / Economy of Means Use the simplest and most cost-effective design strategies. Embrace and use the inherent qualities and beauty of materials in a way that is true to their nature. Design, propose and push for multi-functional spaces that can serve various purposes, reducing the overall size and complexity of a building. Embrace minimalism, not as a fashion or trend, but as where simplicity and clarity become the main aesthetic and practical virtues. Pompous and conspicuous architecture? Not

just google world's most boring jobs. make sure your kids never go into stem. let them live. become a teacher, get paid the same as an engineer and actually talk to people all day.

Engineers can be very valuable in general to society. All graduates education costs are heavily subsidised by society. We owe society. My latest insight is in the no CO2 emissions on climate change (or destabilisation). Electric energy is 15% of all energy used. 100% clean electric energy is a x7 more electricity and no fossil fueled energy. Electric vehicles, EVs, are the acknowledged transport solution. Australia has 20million vehicles. Say 100kwh batteries, 2,000gWh electricity storage daily. Most vehicles are parked 23hrs every day. And will selfplug-in to the national grid. And drive building to building. Australia has 20million buildings and so 6.6kW rooftop PV is 660gWh daily generation. The interesting thing is that Australia fossil fueled generation is 25gW, 600gWh max daily in you are lucky. 400gWh avg. Rooftop PV and selfplug-in V2G EV, with its free big battery, can more than match Australia's fossil fueled generation. I speak up because nuclear promoters say clean nuclear grid electricity is the cheap reliable answer. My engineering tells me to look at the facts. The grid is $1million per km. The grid is 1million km long to 20million buildings, millions and millions and millions and millions of customers. The grid is a $1TRILLION asset and the Australian GDP $1.5 TRILLION. The problem is that x7 more grid capacity is $7TRILLION. And 700 years. The first grid was built over 100years. New grid electricity capacity is a 700 years project. Plus the new, and the extra nuclear generation plants construction costs and time frames. $1TRILLION over 700 years. This nuclear grid electricity appears to be an economic dead duck. Nobody talks about the grid costs in a 100% electric world My observations are that rooftop PV and EV big batteries do not need more grid and can be effective in 2 decades. The existing national grid is protected and unloaded. Rooftop PV is dirt cheap, less than windows $/m2. Big batteries are free with EVs, Hahaha. The stupendously expensive new expanded national grid is not needed. I say all this because Engineers with vested nuclear interests are not speaking accurately. Please comment on this, do the simple maths and then start speaking up. Governments can be influenced. Labour is pushing for distant renewables which have the same grid costs. Snowy 2.0 pumped hydro expansion project budget has exploded. The grid construction costs have exploded the projects $2b to $15b budget. Engineers failed to speak up. Costs are part of engineering and we are part of society. Happy to say more but please look at the economics, the numbers. Engineers are the only ones who can put the real world and numbers together.

I think we need to work out how to deliver it in a better way, and agree with the way we deliver mass infrastructure projects to will never be delivered, and can typically turn into cash cows. But if we looking at in a different way deliver the grid in a distributed way solar panels on all roof, this can significantly reduce the demand on the grid, base load still needs to be worked out but should make it more manageable. Do I think there may need to some Nuclear likely but it isn't going to solve all issues.

You're young? Haven't been exposed to how the real world works yet? I agree with most of what you say. However, there are more pressing issues that don't have government support. Just wait for the world to burn down then we might get a chance to rebuild. Otherwise everything we do is pointless, to say engineers are cogs ina machine would give us even too much credit. When politicians start having personal financial incentives for nuclear, that's when it'll change. If you want to talk about numbers... go investigate the biggest donors to the government.

​@mangoandguitar the Teals got into parliament without big donors. I have decades of experience. Most engineers have mortgages and employers dependent on big projects and big government involvement. Engineers keep their head down. I have worked with a local community group and when the bad projects turned up, extremely talented and highly qualified people secretly helped destroy the councils consultants report or wrote excellent publication materials. One contributor had a University Medal for writing. Another was a Consulting Water Engineer. His huge employer said do not mention their name, but go ahead and help us. His wife was a solicitor and advised him. Hahaha Hahaha 😊 Small groups have changed government. Volunteers make a difference. Professionals want to provide the bullets.

Just what we need, “woke” engineering. When the building collapsed be happy with the thought that DEI was foremost.
