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.
Over decades, concrete, block, stone, and brick foundations naturally weaken as mortar joints decay, tie-rod holes rust out, and block cavities collect moisture, creating new leak paths that didn't exist when the home was built. When looking at a concrete foundation, it isn't a matter of IF it will leak, but WHEN it will leak.
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.
Persistent mold and mildew odors often linger long after water damage occurs, and odor-control products such as AqueLyst SpillMaster are designed to address these smells without relying on harsh chemicals. Addressing these odors without introducing harsh chemicals remains a challenge for many property owners and facility managers. AqueLyst, a brand focused on advanced odor elimination, offers a science-backed solution. Unlike conventional products that simply mask smells, AqueLyst uses molecular-level neutralization to target and eliminate the source of unwanted odors.
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.
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.
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.
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.
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.
