Burning 165 gallons per mile across Florida flatland, the crawler transporter has hauled three entirely different rocket programs across six decades and no replacement has ever been ordered
3+ hour, 6+ min ago (708+ words) The gravel under it gets ground to powder. Not all at once. Surveyed and replenished, because each steel tread shoe weighs about a ton, and there are 456 of them. The machine covers four and a half miles of Florida flatland…...
Steel arch spans weighing 5 million pounds each rode the Hudson River for 30 hours apiece, and crews then jacked all three of them 60 feet straight up over the Hackensack
14+ hour, 6+ min ago (867+ words) Three tugboats sat in the dark water at the Port of Coeymans, lines taut, waiting for the tide. Behind them on a heavy barge rode something that weighed five million pounds and stretched 400 feet from end to end. It was…...
Dried sea lettuce ground into powder and blended into cement at 5 percent of the mix by weight held construction grade strength while cutting the cement's global warming footprint by 21 percent
15+ hour, 6+ min ago (686+ words) The bowl of green powder on a lab bench in Seattle looked like something from a kitchen, not a construction site. It was sea lettuce, the same limp weed that drifts through cold Pacific Northwest shallows. A research team dried…...
Each of the 89 concrete boxes being cast beside a Danish harbor is 712 feet long and gets towed to sea by tugboats, while the box itself very nearly floats and is sunk on purpose with water pumped into it
3+ day, 7+ hour ago (786+ words) Weight is not what makes an object hard to move across water. Displacement is. A ship of 80,000 tons is moved by tugs every day of the week, and nobody finds it remarkable. So the interesting question about a tunnel section…...
Two gantry cranes going up over a dry dock in Dalian span 840 feet between their legs and hoist a load 328 feet into the air, which is a span no shipyard crane anywhere has matched
3+ day, 8+ hour ago (805+ words) A shipyard crane is not really limited by what it can lift. It is limited by how far apart its two feet can stand while it is still lifting that load. Widen the span and the girder between the legs…...
Crews searched 3 square miles of sea ice in Greenland by walking shoulder to shoulder in a line and scraping up everything black, but the second stage of one weapon has never been accounted for
3+ day, 16+ hour ago (797+ words) A nuclear weapon torn apart by fire and impact does not go off. That sounds like luck. It is design, and it was designed in deliberately. The package only works if a precise sequence happens in a precise order, and…...
Walls barely 7 inches thick were all that held up 42 grain silo tubes in Cape Town, while the way to carve a museum out of them turned out to be adding concrete first rather than removing any
4+ day, 7+ hour ago (792+ words) Forty two concrete tubes packed side by side on the Cape Town waterfront, eighteen feet across and a hundred and eight feet tall. They held maize for most of a century. Then they held nothing. The walls are seven inches…...
A 461 foot rock installation ship built in Philadelphia carries 22,000 tons of stone in its hold, while an inclined pipe under the hull puts that stone on the seabed one load at a time
4+ day, 9+ hour ago (846+ words) Stand on the quay and the ship reads as a bulk carrier with something extra bolted through it. A steel tube runs down from a house on deck, through the hull, and out below the waterline at an angle, and…...
One crane vessel set all 72 foundation tubes for Denmark's largest offshore wind farm in five months, and the covers capping their open tops were designed to be taken off and used again
4+ day, 20+ hour ago (808+ words) A yellow steel tube stands in open water off the Danish coast with nothing on top of it. It went in on the last day of April. It has been standing there ever since. The top is open, and a…...
Two shore cranes 302 feet tall were lashed to the deck of a 554 foot carrier bound from Germany to Thailand, but a Bay of Biscay storm put nearly all of both into the sea off Galicia
5+ day, 8+ hour ago (780+ words) A container crane is designed for one thing above all else. To stand on a quay, perfectly level, forever, with its whole weight pressing straight down through four legs into concrete. Every assumption in the steel follows from that. Then…...
