Скачать или смотреть How The Steel Bridge Rose Across a River Canyon in Weeks. Mega Construction & Bridge Engineering

Step inside the world of large-scale construction and infrastructure engineering—where 1,000-ton bridge arches are floated on barges with millimeter precision, steel columns are spliced and bolted to resist wind and earthquakes, canals reshape global trade, and chip fabs rise to power the digital age.

We start with how modern steel frames grow skyward using column splices and high-strength bolted connections, why engineers place splices near floor levels, and how seismic detailing protects buildings. Then we jump to megaprojects: the Panama Canal expansion with rolling gates and water-saving basins; the Walterdale Bridge in Edmonton, where ironworkers guided a 1,000-ton center span upstream and lowered it onto skid shoes; and TSMC’s $40B semiconductor fabs in Phoenix. Finally, we get practical on site: calculating pipe slopes, seating reinforced concrete pipe to catch basins, and paving rigid shoulders with a side paver for safer highways.
