Your points are definitely valid criticisms. And the world (for CS-type folks) would certainly be better. For everyone else, I think it would be a whole lot worse. I don't think its a stretch to say excel had enabled billions (trillion

It’s also worth noting that geotechnical engineering is a high risk and low tech field. Most of their design relations involve pounding a stick into the ground and counting how many hits it took to sink a unit depth (that’s a little bit jes

This is something that the profession has done a terrible job in communicating with the public. But if you think about the nature of earthquakes, it starts to make a little more sense. There is basically a probabilistic distribution of eart

I’ve spent a cumulative 6 months there (3 separate trips) including 3 months with a 1 and 3yo, and never was there a point where I felt unsafe. I am a tall white guy and stand out. Met lots of curious, friendly, amused locals that wanted to

We’ve been misled for so long into thinking this is a consumer problem that needs downstream solutions. Actually I think it’s a regulatory problem that needs upstream regulation

Not sure, it’s not been proposed on our projects before. Most likely, that means it’s not cheaper than geofoam or fill.

We use this a lot to support landscaping in the sky (rooftop terraces and such on high rises) which is an architectural trend that really needs to go away. There is nothing green or sustainable about the extra concrete needed to support it.

In this case the city proactively made all its files available for the building. In general, that doesn’t happen (perhaps in Florida it does, I have no experience there). But most cities will only release their record drawings if you have p

Not sure why you're being downvoted, because you're right, atleast on the west coast of north america. My firm hasn't use epoxied rebar since like 1990, and we removed all references to it on our drawings long ago. The coatin

One of the big reasons is ductility. We want structures to show signs of distress before failing catastrophically. With ductile reinforcing (steel), the deformation at which failure occurs is easily 5 times larger than the deformation where

One thing I noticed in Chinese cities is that they often had a cleaner assigned to each block. They would have a blue jumpsuit, broom, shovel, and wheelie bin. In the big cities, streets were very clean.

I haven’t heard of NEET before, so I looked it up. NEET, an acronym for "Not in Education, Employment, or Training", refers to a person who is unemployed and not receiving an education or vocational training

Very good point. Most building projects actually use admixtures to get as rapid strength increase as possible, even if it means less strength increase long term, because the early strength determines when you can strip formwork and start bu

Welding rebar is almost never used in North American building construction, and is actually forbidden in high seismic zones. But then again so is stainless steel rebar and carbon fibre rebar and most of these other types of products because

I think many commentators, including yourself, have an erroneous assumption about structural design which is roughly summarized as: the inputs are known with certainty. This is really not the case especially when considering natural hazards

Plain concrete is simply not allowed by code for many applications. So even if you could theoretically justify the design, you couldn’t get the permit to build it. Physics, economics, and bureaucratics is a good summary of structural engin

In many parts of North America, testing and upgrades are only triggered with a change of use, or if required by buyers during sale of a building. The state does not maintain any kind of testing program of private buildings. One exception is

Fun fact, because of that earthquake, there is a 160ft height restriction on certain types of construction in US building codes even to this day!

Not op but our mortgage lender offers a “total home warranty” for like $8/month which covers appliances and systems (hvac, boiler, etc). It’s basically appliance insurance. And at that price it’s a pretty good deal when buying a used h

But the Supreme Court doesn’t make the rules, it just interprets them. The rules are made by elected representatives.

Many earthquake engineers and researchers are all too familiar with Tcl, because for years the preeminent structural analysis tool OpenSees [1] required Tcl scripts to use/run. Just in the last few years was it forked to python. https

> An unforgivably naive market of architects and contractors then began merrily specifying it for a wide range of uses well beyond its original test. Architects are architects, Contractors are contractors, and neither are fire engineers.

Perhaps I misunderstood your description of subfloor, but I don’t think it’s common anywhere to insulate between interior floors or walls.

Good points, it makes you wonder how many day to day things could have vastly improved user experience if government efforts were targeted at underlying problems instead of symptoms (borrowing your definitions of those two things). But plas
