The rods are the central element of a novel seismic-responsive structural system that is designed to help the building snap back to its original shape in the event of a major earthquake. Their trick is an embedded cluster of taut cables made from a highly flexible compound called a shape-memory alloy that's capable of bending under tension-like the lateral shaking in a California earthquake-and then straightening out.
A bridge failure might sound like something from a blockbuster, but real damage usually creeps in slowly. Across the nation, engineers watch thousands of bridges that remain open, yet are far from their best condition. "Structurally deficient" is not a death sentence, but it signals repairs can no longer wait. These 10 bridges handle massive traffic and are a serious concern nationwide today.
So many homes now have high efficiency sealed combustion boilers and furnaces that do not vent out through the chimney at rooftop height. These units typically will have their intake and exhaust going out through the side of the house. These do need to be high enough off the ground to allow for typical snow patterns, but snow drifts due to high winds can pile pretty high, and this next storm is coming with very high winds.
Raising the roof is a major structural change, but for some homeowners, it can be a practical way to gain space and modernize a home without relocating. Whether the goal is higher ceilings, an added level, or turning unused attic space into livable square footage, the idea to raise a roof on a house often comes up when a home no longer fits everyday needs.

Work to fix hospitals built using unsafe concrete will not be completed in time to meet the government's target, a new report has warned. Seven hospitals built using Raac, or reinforced autoclaved aerated concrete, were prioritised for remedial work last year, with the government setting a deadline of 2030. The new buildings are now expected to open in 2032 and 2033 - but some are already facing pressure to meet the revised timetable, the National Audit Office (NAO) said.
Beneath the visible surface of cities lies an invisible architecture. Subways, tunnels, water systems, data cables, and bunkers form a dense network that sustains urban life while remaining largely unseen. The ground beneath our feet is not a void but a complex territory that holds the infrastructures, memories, and anxieties of our age. In recent years, as land becomes scarce and climate pressures intensify, architects and urbanists have turned their gaze downward, rediscovering the subterranean as both a physical and conceptual frontier.
Unlike planning drawings that focus on external appearance and planning policy, building regulation drawings dive deep into the technical specifications-showing construction methods, materials, structural elements, insulation values, ventilation strategies, and safety features. These drawings serve as your blueprint for compliance, providing Building Control officers with the information they need to assess whether your project meets the legal requirements for structural stability, fire safety, energy efficiency, accessibility, and overall construction quality.
Several crew members of a ship that collided with a bridge in Baltimore almost two years ago are still being held in the US by federal authorities despite the fact that no criminal charges have been brought against them. In the early hours of 26 March 2024, the MV Dali departed the port of Baltimore bound for Sri Lanka. While navigating the Fort McHenry channel, the 1,000ft-long Singapore-flagged cargo vessel lost power before striking the bridge. The impact resulted in the deaths of six people who were working on the bridge at the time.
It's 2:30 PM on a Tuesday. You're at work. A text arrives from your neighbour: "Your roof tiles are falling in your garden." Your stomach drops. You're thirty minutes from home. You can't leave work immediately. Even if you could, what would you do? Your roof is damaged. You don't have a roofer's number. You don't know what to do first.
In fact, it acts as an insulator that protects the shingles. And, even when it's deep, the snow's weight is less than what the roof is designed to bear; the average roof is built to carry loads of 65 pounds per square foot. Even flat roofs, which seem more vulnerable to snow loads than pitched ones, are pretty tough. In fact, residential flat roofing is stronger than commercial roofs.
The city passed legislation nearly 18 months ago requiring property owners to retrofit their multi-story, wooden-frame buildings with at least three units constructed before 1990. It delayed implementation, however, when the federal government rolled back significant funding to facilitate the repairs. But after a court-granted injunction required the release of some of those federal funds, the city approved a $1.6 million pilot financing program in hopes of rolling out a larger critical life-safety initiative in the future.
Cedar Street just came out victorious in a multi-year saga with the city of La Canada Flintridge, winning the first successful builder's remedy case in California Superior Court for its 80-unit mixed-use project at 600 Foothill Boulevard and setting a path for other developers to build. But the fight may have left its scars, in time, stress and now soured relationships with some officials.
