Chicago's Micropile Debut
On a tight, urban site around Chicago's historic Orchestra Hall, engineers used high-capacity micropiles as an alternative to hand-dug caissons. On a $104 million project...
Soft Ground Improvement in Lowland and Other Environments
The presence of thick deposits of soft clay combined with the effects of ground subsidence cause problems for engineering constructions for lowland areas such as the Central Plain (Chao...
Singapore Showcase
A new bridge in Singapore has a unique pylon design and no piers. The deck hangs from the pylon supported by three back stays. The 100 m overpass bridge was designed for the Singapore...
