A Good Foundation

It takes a strong foundation to build a house and a stronger one for a bridge. This resource presents the effects of geology and soil on bridge foundations. Working in groups, the class investigates the interaction of shallow and deep foundations with the soil layers. The teams calculate the bearing pressures from the data collected during their investigation.
