Building implosion
In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings. Despite its terminology, building implosion also includes the controlled demolition of other structures, like bridges, smokestacks, towers, and tunnels. This is typically done to save time and money of what would otherwise be an extensive demolition process with construction equipment, as well as to reduce construction workers exposure to infrastructure that is in severe disrepair.
Building implosion, which reduces to seconds a process which could take months or years to achieve by other methods, typically occurs in urban areas[citation needed] and often involves large landmark structures.
The actual use of the term "implosion" to refer to the destruction of a building is a misnomer. This had been stated of the destruction of 1515 Tower in West Palm Beach, Florida. "What happens is, you use explosive materials in critical structural connections to allow gravity to bring it down.
The term "implosion" was coined by my grandmother back in, I guess, the '60s. It's a more descriptive way to explain what we do than "explosion". There are a series of small explosions, but the building itself isn't erupting outward. It's actually being pulled in on top of itself. What we're really doing is removing specific support columns within the structure and then cajoling the building in one direction or another, or straight down.

Building implosion techniques do not rely on the difference between internal and external pressure to collapse a structure. Instead, the goal is to induce a progressive collapse by weakening or removing critical supports; therefore, the building can no longer withstand gravity loads and will fail under its own weight
Numerous small explosives, strategically placed within the structure, are used to catalyze the collapse. Nitroglycerin, dynamite, or other explosives are used to shatter reinforced concrete supports. Linear shaped charges are used to sever steel supports. These explosives are progressively detonated on supports throughout the structure. Then, explosives on the lower floors initiate the controlled collapse.
A simple structure like a chimney can be prepared for demolition in less than a day. Larger or more complex structures can take up to six months of preparation to remove internal walls and wrap columns with fabric and fencing before firing the explosives.

Royalroad web fiction slop posting:
From Londoner to Lord is interesting. It's not really very well written, in a literary or storytelling sense. But from the perspective of tickling my specific autism just right, it's great. One recent chapter was basically just an explanation of how fish ladders work.
The premise is a Connecticut Yankee style isekai played completely 100% straight. Our protagonist is a modern engineer and big ol' nerd bodyswapped into an exiled third son of a baron, sent to administer the poorest, failingest village in the land. The setting is sort of medieval fantasy, except there's no magic beyond the initial isekai event.
On arriving in his new village he finds starving people, decaying homes, no farmland, and a flooded coal mine. So he sets about trying to fix it, partly by designing era-appropriate labor saving devices like wheelbarrows, log haulers, and seed drills.
But actually the most impactful things he does are basically all the stuff a fresh communist revolutionary government in an underdeveloped formerly feudal state does. Abolishes slavery, does land reform, institutes food aid and builds public housing, starts universal schooling for children and an adult literacy program, arms women, and starts developing productive forces.
I will check this out! I just finished Ranked Competitive Breast Growth which is excellent although very NSFW
What a title, I'll give that a look
