President Donald Trump says the U.S. military is building a massive complex beneath the White House ballroom, ahead of schedule, with the ballroom reportedly serving as a shed for the underground work. The privately funded project has seen its budget double from $200 million to $400 million as renovations expand, and Trump has floated additional plans such as renaming the Kennedy Center and proposing a grand arch in Washington.

Seawater and CO2 turn into carbon-storing cement ingredients

Researchers show that seawater and carbon dioxide can be converted in a tabletop reactor into solid minerals (calcium carbonate and a magnesium-rich solid) that can form powders or grains, potentially replacing mined sand in concrete and, in some mixes, store more CO2 than the process emits (carbon-negative). If powered by clean energy and scaled up, near‑shore modular reactors could sequester CO2 at the source and reduce cement's climate impact, though durability and wear tests at larger scales are still needed.

White House eyes underground security hub beneath Sherman Park

The White House is seeking to build a 33,000-square-foot underground security screening center beneath Sherman Park to streamline visitor checks, with seven lanes and a target to open by July 2028, as part of a broader grounds overhaul. The plan, developed with the Secret Service and National Park Service, will be reviewed by the National Capital Planning Commission in April, and a separate proposal for a 90,000-square-foot building with a ballroom at the former East Wing site is also under consideration, while the Sherman Park monument would remain intact.

Oceanwide Plaza's new owners brace for costly graffiti cleanup

New buyers of downtown LA's Oceanwide Plaza—often called the graffiti towers—must tackle graffiti removal first, with cleanup possibly costing hundreds of thousands to millions of dollars; experts describe chemical stripping for concrete or glass-bead blasting for paint on glass, plus significant challenges on 500-foot towers and safety planning, as the $470 million sale awaits final court approval.

America's Roofers Vanish as Immigrant Labor Redefines Construction

A New York Times investigation tracks how American-born roofers disappeared as immigration reshaped the field: unions lost power in the 1980s, nonunion labor rose, and many immigrant workers—often undocumented—entered residential construction during housing booms, fueling labor shortages, lowering relative wages for some workers, and contributing to rising home prices and housing-affordability pressures.
