Why the first metres of a bridge project happen underground — and how soil data drives foundation choice.
Bridge failures rarely start in the deck; they start in the ground. Careful subsurface investigation determines whether we pursue spread footings, piles or caissons.
For Bhutan's river valleys, seasonal scour and seismic loads dominate the design envelope. We combine SPT data with dynamic analyses to size foundations that outlast their design life.
