Island Time 710 Posted September 22 Report Share Posted September 22 I trained as a mechanical engineer. But I've not seen design details of this bridge, so I cant make sensible comments. Uninformed comment is usually not worth the time it took to write it, or read it! Ed 1 Quote Link to post Share on other sites
Romany 60 Posted September 23 Report Share Posted September 23 But whats your point IT 🤔? Not posting uninformed opinion would be the death of ZB and -dare I say it, forums like this. Quote Link to post Share on other sites

lateral 107 Posted September 23 Report Share Posted September 23 Yeah well to each there own perspective, another out of context post of engineering smugness. Yes, exactly what is your point IT? Nobody here suggested that standard bridge building protocols shouldn't be followed, that the steel didn't need to meet the requirements of the original, the compressive or tensile (or cyclic) loading of the insitu member(s) were not allowed for on installing new member, the methodology of installing a preload in it and that specification peer reviews were unnecessary. What I was lamenting, in less than useful phraseology, was that NZ lags behind average OECD productivity and it shows in how long everything take and how much it costs. We have made an industry of putting people in the way. Kudos to the crew that got the temporary member in and go well on the permanent one. Quote Link to post Share on other sites

Small talk on the other hand.... Are you saying small talk is a train wreck? or are you trying to demonstrate the ductility of railway tracks? I don't have a lot to do with steel, but I was involved in a project to install a new high pressure gas pipeline (technically I think it was medium pressure, ahem). Anyway, steel pipe will behave like a piece of spaghetti if you weld it together into a long enough string. Turns out you can drill it under and around all sorts of things. The main physical constraint is the ability to steer the drill head, which is largely to do with the geotechnical properties of the ground. lateral 1 Quote Link to post Share on other sites

Fish 534 Posted September 26 Author Report Share Posted September 26 NZTA now aware that cold fronts may bring high wind gusts... Lanes on the Auckland Harbour Bridge are being closed on Sunday morning ahead of a forecast wind shift that could see gusts of up to 90kmh. There are currently northerly wind gusts of up to 70kmh in Auckland, but the bridge is relatively sheltered. However, Metservice is forecasting a wind shift from the north to the west in the morning, which could bring winds of 80kmh to 90kmh. “The wind shift could bring a swift change in the strength of the gusts, so as a precaution we will close one southbound lane and two northbound lanes on the bridge until the wind settles,” said Waka Kotahi NZ Transport Agency senior journey manager Neil Walker. https://www.stuff.co.nz/auckland/300117484/auckland-harbour-bridge-lanes-close-as-winds-tipped-to-reach-110kmh Quote Link to post Share on other sites
marinheiro 139 Posted September 27 Report Share Posted September 27 they should have painted the temporary piece of pipe Harbour Bridge Gray, too many people slow down to look at the temporary repair Quote Link to post Share on other sites
