Let’s set the record straight for a few construction misconceptions!

Errata: The shot at 4:16 is of the Greek Acropolis (not a Roman structure).

Over the past 6 years of reading emails and comments from people who watch Practical Engineering, I know that parts of heavy construction are consistently misunderstood. So, I pulled together a short list of the most common misconceptions. Hope you don’t mind just a little bit of ranting from me 😉

This Is Why We Can’t Have Nice Infrastructure

America is a land of constant progress. Sometimes it seems like there’s nothing we can’t accomplish. And then we try to build something…

In recent years, infrastructure projects have taken way too long and cost way more than they should. Boston’s “Big Dig”, for example, took 15 years and cost more than 5x as much as projected. California’s High-Speed Rail was supposed to run between L.A. and San Francisco by 2020. Instead, some track nowhere near either city might be ready by 2027.

Why can’t America build quickly or cost effectively anymore? A well-intentioned regulatory law from the 1970s has a lot to do with it…

When the National Environmental Policy Act (NEPA) first took effect in the 1970s, the environmental impact analysis it required from builders before a project could begin would often run less than 10 pages. Today, the average is more than 600 pages.

Maybe delays and ballooning costs are worth it to protect the planet, right? Here’s the crazy part: NEPA doesn’t even guarantee that. In some cases, it’s actually making us less green.

The bridge design that helped win World War II

It’s a simple innovation that helped win a war.

The Bailey bridge was Donald Bailey’s innovative solution to a number of wartime obstacles. The allies needed a way to cross bodies of water quickly, but bombed-out bridges — or an absence of crossings entirely — made that incredibly difficult. That was only compounded by new, heavy tanks that needed incredibly strong support.

Bailey’s innovation — a modular, moveable panel bridge — solved those problems and gave the allies a huge advantage. The 570-pound steel panel could be lifted by just six men, and the supplies could fit inside small service trucks. Using those manageable materials, soldiers could build crossings sufficient for heavy tanks and other vehicles.

As impressive, the Bailey bridge could be rolled across a gap from one side to the other, making it possible to build covertly or with little access to the other side. Together, all the Bailey bridge’s advantages changed bridge construction and may have helped win the war.

QotD: Chinese “technocracy”

Filed under: China, Education, Government, Quotations — Tags: , , — Nicholas @ 01:00

For a while, all (or almost all) of China’s top officials had engineering degrees.

When Xi Jinping first joined the Politburo Standing Committee in 2008, eight of its nine members were engineers. Paramount Leader Hu Jintao was a hydroelectric engineer. His second-in-command Wen Jiabao was a geological engineer. There were two electrical engineers, a petroleum engineer, a radio engineer, and two chemical engineers (including Xi himself). The only non-engineer was Li Keqiang, an economist.

And this was actually a low point in engineers’ dominance of Chinese power. The term before, 100% of Politburo Standing Committee officials had been engineers! What’s going on?

For one thing, Deng Xiaoping thought engineers were cool, and he was powerful enough to do whatever he wanted. A government made up entirely of engineers? Sure, whatever you say. And since the top echelons of Chinese government appoint their own successors, these engineers could appoint other engineers and so on.

But also: during the Cultural Revolution, about half of Chinese people who got degrees at all got engineering degrees. The Cultural Revolutionaries were really not big on education (according to one article, “Xi’s secondary education [was cut short] when all secondary classes were halted for students to criticise and fight their teachers.”) But engineering was useful for building factories, and so was grudgingly tolerated. That meant that of the people smart and ambitious enough to get into college at all, half did engineering.

The other half? I’m not sure. Law is a popular major for would-be politicians in the US, but here’s a Chinese person explaining why it doesn’t work that way in China (short version: China doesn’t have great rule of law, so lawyers don’t matter much and are low status).
Here is an article telling us not to take China’s engineer-kings too seriously. It argues that (aside from Deng’s original picks), most of them never did much engineering, and just studied the subject in school as a generic prestigious-sounding degree to springboard their government career. Chinese engineering curricula are easy, and powerful people frequently cheat or pay others to write their dissertations.

Aside from a few of Deng’s personal picks, we should think of this less as “China is a magic place where rational scientists hold power”, and more as “for idiosyncratic reasons, social climbers in China got engineering degrees.” Certainly none of these people were selected for the Politburo on the basis of their engineering acumen. They got their power by bribing, flattering, and backstabbing people, just like everyone else.

In any case, Xi’s old Politburo class was the last one to be made primarily of engineers. The current Politburo has only one engineer — Xi himself.

Few things of the Second World War are more intimidating than the iconic German bunker. Made out of reinforced concrete with a thickness of up to 3.5 meters, these casemates and pillboxes were incredibly tough to destroy. Built to withstand shells and bombs, they provided shelter to troops and civilians alike. But there were also some even larger super-structures. From giant U-Boat shelters and fearsome Flak-Towers, to the ultimate Führerbunker, the Germans perfected the art of bunker building.

Why SpaceX Cares About Dirt

Published 2 Nov 2021

Why do structures big and small sink into the ground, and what can we do to stop it?

Before the so-called Starbase supported crazy test launches of the Starship spaceflight program, it was just a pile of dirt. After nearly two years, they hauled most of that soil back off the site for disposal. It might seem like a curious way to start a construction project, but foundations are critically important. Building that giant dirt pile was a clever way to prevent these facilities from sinking into the ground over time.

Engineer’s Delight: Stemple 76/45 Becomes the Stemple Takedown Gun

Forgotten Weapons
Published 17 Sep 2021

Cool Forgotten Weapons merch! http://shop.forgottenweapons.com

The saga of how the original Stemple 76/45 became the Stemple Takedown Gun is a fantastic story of engineering design choices.

Essentially, John Stemple began by building a rather crude copy of the Swedish K in .45 ACP in the mid 1980s, called the Stemple 76/45. He produced and registered 2,000 transferrable receivers for the gun (pre-1986), but only built them slowly, a few at a time. In the late 1980s he faced criminal charges from ATF, and transferred the receivers to a friend while he (successfully) fought the charges. When he went to get the receivers back, his friend refused, and the two entered into a nearly decade-long legal battle over them.

By the time Stemple eventually won the case, he recovered about 900 transferrable tubes. By this time (circa 2000) these tube receivers were much more valuable than when he first made them, as the machine gun registry was closed in 1986 and new ones can no longer be made. At this point, Stemple reached out to Brian Poling (BRP Corp) to act as a subcontractor to make the parts for the Stemple 76/45. But Poling had a better idea …

Poling’s thought was to instead design a new gun that would be much more desirable as a recreational gun than the 76/45. He envisioned something controllable, low recoil, and using large drum magazines. Such a gun would be a lot more fun at the range than the MACs and Uzis that tended to dominate the submachine gun market at the time. In addition, Poling’s gun would be designed specifically to protect the irreplaceable registered receiver tubes from wear or damage. The result was the STG-76 — the Stemple Takedown Gun.

In order to remain legal, the STG-76 had to leave the original 76/45 receiver tube cutouts unmodified, so as not to change the configuration of the receiver itself. Poling designed a replaceable internal trunnion and slip-over magazine well, allowing multiple different calibers and magazine configurations. The internals were closely based on the Finnish kp31 Suomi, for which parts kits became readily available in the early 2000s. This also facilitated the use of Suomi 71-round drum magazines. The original STF-76 design also included a bipod for easy shooting, and a grip and stock from an HK91 or CETME Model C for comfortable handling (instead of the terrible metal strut stocks common to most budget SMGs).

Several other interesting configurations would follow (stay tuned for those videos), and the guns remain available brand new to this day. The original supply of receivers is sufficient for production until about 2023 …

Fallen Flag — the Western Pacific Railroad

Filed under: Business, History, Railways, USA — Tags: , , , , — Nicholas @ 03:00

This month’s Classic Trains fallen flag feature in the Western Pacific Railroad by Arthur L. Lloyd. The first major railroad to bear the name Western Pacific was a short-lived corporation formed to build the furthest-west portion of the first transcontinental railroad between Sacramento and San Jose in California. It operated from 1862 until 1870 and at that point was merged into the Central Pacific. The second entity to bear the name began life as a plan by George Jay Gould (son of the famous — or infamous — Jay Gould) to create a western connection for the Gould-owned Denver and Rio Grande Western. D&RGW had lost access to its earlier western link with the Southern Pacific due to a Harriman-owned Union Pacific attempt to acquire the SP. The new Western Pacific Railway was formed in March 1903, although Gould attempted to hide his involvement in hopes of preventing further obstructions being thrown up by opponents like Harriman.

The Western Pacific company magazine Mileposts included this historical snippet in their 50th anniversary issue (courtesy of the Western Pacific Railroad Museum):

Virgil Bogue had become George Gould’s consulting engineer and recalling his surveys for the Union Pacific in the ’80’s, recommended Beckwourth Pass and the Feather River route. Remembering also an unhappy experience he had once had in locating any other road, only to find the whole route plastered with mining claims of dubious mineral value but through which rights of way must be negotiated, he advised Gould to form a “mining company” first. Accordingly the North California Mining Company was organized and soon nearly 600 placer claims were staked out, blanketing the entire proposed route across the mountains.

Gould turned the job over to the Denver and Rio Grande and its president, E.T. Jeffery, sent a field party under H.H. Yard west to locate the line. It was all top secret. The transit men and stake artists were forbidden even to let their wives know where they were. Letters could only be exchanged through the Denver office of the railroad. Two California corporations, the Butte and Plumas Railway and the Indian Valley Railway, were set up to be the figureheads.

[…]

George Gould still remained completely out of the picture and denied all connection with the project. Although he financed the new surveying parties that were immediately sent out to make the final location, he was forced, in the interests of this secrecy, to keep the Rio Grande engineers in the field as well. The absurd result was two hostile groups struggling to outwit each other and often on the point of exchanging pot shots, though both were actually on the same payroll.

After much chicanery and effort, the railway’s right of way through the Feather River Canyon, the next historically significant fight was securing access to the waterfront along San Francisco Bay, where the legal department of the Southern Pacific believed they had an ironclad monopoly of all the potentially useful access routes to salt water:

… the S.P. was fully confident that it would have but little difficulty in isolating the Western Pacific from a practical outlet on the Bay. The Santa Fe, only a few years before, had built its ferry slip way up at Point Richmond rather than attempt to crack the S.P. stronghold. Bartnett, after a hard struggle against the older railroad’s influence, did secure a small site on the mudflats of the Oakland Estuary. It would have made a miserably cramped ferry terminal but, from all appearances, the WP promoters had concluded it was the best they could do. Harriman’s forces sneered and relaxed. Gould’s were just beginning. Every move was carefully rehearsed and logistics figured to the last detail.

As the Oakland tidelands had gradually been filled in, the Government had extended the banks of San Antonio Estuary with rock quays called “training walls” in order to prevent silt from washing into the Oakland inner harbor channel. A dredger was often necessary to prevent the formation of a bar at the entrance of the channel. This dredger became the Trojan horse of the Gould attack.

On the night of January 5, 1906, the Western Pacific forces under Bartnett struck.

With 200 workmen and 30 guards armed with carbines and sawed-off shotguns, he used the dredging company as a front, and seizing the north training wall, began feverishly to lay a rough track. Most of the guards took up positions at the shore end of the U. S. training wall and maintained them night and day. Laborers snatched their sleep in shelter tents on the wave-washed rocks and the WP commissary department fed them. Scows rushed more rails and ties across the Bay to the end of the wall. Soon there was a mile of track on top of the rock wall.

Of course the Southern Pacific did not quietly accept this outrageous trespassing on domains it had held undisputed for more than half a century. Its legal department, fairly in convulsions, was whipping out the necessary papers for immediate appeal to the law. This was exactly what Bartnett had told Gould would happen and exactly what they both desired. For the courts, as Bartnett had felt sure they would, held that the Southern Pacific title to the waterfronts had not progressed westward with the shoreline as the tidelands and marshes had been filled in, but was valid only to the low tide line of 1852. The S.P.’s “waterfront” therefore was by now well inland, and the new marginal land surrounding it was the property of the city.

The city government was duly grateful to the new railway for almost literally liberating the city’s shoreline from the grip of the Southern Pacific. With most of the legal complications (and paramilitary solutions) out of the way, construction of the full line began in earnest, as Arthur L. Lloyd picks up the story:

Construction started in Salt Lake City. The line would be all 90-lb. rail and have no curve exceeding 10 degrees. To keep to the 1-percent maximum grade, the full-circle Williams Loop was built between Massack and Spring Garden, Calif., and another partial one, Arnold Loop, west of Wendover, Nev.

Work also went from Oakland eastward, and the last spike marking completion was driven on the bridge over Spanish Creek at Keddie, Calif., on Nov. 1, 1909. There was no ceremony. Section foreman Leonardo de Tomasso, age 25, did the honors with a standard steel spike. Arthur Keddie was still around, though. He rode WP’s first passenger train, and he spoke from the Plumas County Courthouse steps in Quincy, Calif., on Nov. 21, 1910.

WP was dispatched completely by train orders and timetable; its only block signals were on the paired track between Weso (Winnemucca) and Alazon (Wells) in Nevada, where eastbound WP and Southern Pacific trains used WP, while both roads’ westbounds used SP.

Route map of the Western Pacific, published in The Architect & Engineer of California and the Pacific Coast, 1905.

WP’s map was simplicity itself, highlighted by a main line from San Francisco Bay to Salt Lake City and a connection with the Rio Grande. The branch to Bieber, Calif., completed in the 1930s, connected to a Great Northern line.
