ICE Code of Professional Conduct, Rule 3:."All members shall have full regard for the public interest, particularly in relation to matters of health and safety, and in relation to the well-being of future generations." β.
In May this year, @LordPeterHendy pressured my now-former employer @SYSTRA_UKIRL to sack me by threatening them. Why did he do this? Because I'd highlighted safety and accessibility issues at Euston station. He is unfit for office and should resign.

A big vertical brown cloud and a sprinkling of sheet piles: signs of a job well done.
That's some pic from our very own @JustinKernoghan who was on the ground when a controlled explosion was carried out on a WW2 bomb. Full story here.

Another big WW2 bomb, another big protective sand enclosure, another successful disposal keeping a community safe, not far from where I grew up. Well done to 321 EOD & Search (@11_EOD_Regiment) and colleagues! π₯.
Watch: The moment a World War Two bomb is destroyed in a controlled explosion in Newtownards.

A huge cantilevered concrete slab covered in screens, with greenwashing ticker tape scrolling up the sides. I guess the jaunty angle represents imminent ecological collapse?
Standing at a 24-degree angle spanning across the area equivalent to two soccer fields, The Kingdom of Saudi Arabia Pavilion features innovation through its advanced multimedia tech integrated into its concrete structure. Learn more β‘οΈ

Philosophy of engineering: at what span to width ratio does a bridge become a culvert?.
Amazing to think that, after over a 100 years of being confined to a culvert, that daylight is coming to this section of the Sheaf. Once the culvert is removed the plans promise a matching parapet to this one. Then we will have a new bridge in #Sheffield π€ͺ

What's more annoying than noisy utilities works outside your open window on a hot summer night? Whatever contracting daftness that leads to the faded stop line only being made good where it intersects the patch. Probably saving a tenner's worth of thermoplastic tape and propane.

π’ New paper in Proc Royal Society A, investigating the effect of atmospheric oxygen on the energy release and pressures generated from plastic explosives in confined spaces, with a particular focus on detonation product and binder afterburn. π
royalsocietypublishing.org
When explosives detonate in a confined space, repeated boundary reflections result in complex shock interactions and the formation of a uniform quasi-static pressure (QSP). For fuel-rich explosives,...

I fear in all the election news an important issue has fallen through the cracks. I am of course taking about the weeks-long shortage of Racer bars at @AldiUK. The people need stability at this time of uncertainty and change!
