Hidden in Plain Sight
In Rome, the new headquarters of the BNL-BMP Paribas Group banking organization is squeezed onto a narrow stretch of land between a railway station and a set of roadways. Yet the site helped yield a stunning...

Permanent Sensors Turn Construction Project into Long-term Research Study (part of "Room To Grow")
The Centre for Smart Infrastructure and Construction (CSIC) at Cambridge University, in conjunction with Arup, has placed fibre-optic cables that will serve as permanent sensors on the underground structure...

Pipeline Protection
To improve the seismic reliability of three critical pipelines, California’s Santa Clara Valley Water District installed what is believed to be the first large-diameter earthquake-resistant ductile iron...

A Good Cause for a Causeway: How Geotechnology and Project Delivery Restored a Roadway Embankment Crossing a Historically Challenging Soft Ground Site
As part of a Minnesota Department of Transportation (MnDOT) design-build project, a causeway was constructed in 2017 to replace an aging bridge in the southwest metropolitan area of Minneapolis. The causeway...

Fast Forward: One Small Step
A concept design for an inflatable habitat on Mars incorporates indigenous ice as a structural element and a shield to protect occupants from galactic cosmic radiation....

State of the Practice for Laboratory Testing of Soft Soils: It's All in the Details
As with all material testing, soils testing has undergone dramatic advances in technology because of computer automation. In the 1970s, laboratories were filled with dial gages, proving rings, mercury...

Avoiding Impacts of Collapsed Mines on Railways: A Multidisciplinary Geophysical Detective Approach
The presence of abandoned mine workings can pose a significant risk to the use and development of surface structures above them, including railway lines. Typically, the adverse and often sudden effects...

Design of the Future Mexico City Airport: Attaining Resilience in Soft Ground
The Lake Texcoco region to the east of Mexico City is famed for its deep lacustrine deposits of compressible clay, which amplify ground shaking during seismic events. The area is also gradually subsiding...

Timber Rising
Ever-taller buildings made from engineered wood are being proposed and constructed around the world. To meet that demand, designers are being tasked with learning about the new capabilities, attributes,...

As We See It: Is Understanding the Stress History and Behavior of Soft Soils at Risk of Taking a Back Seat?

A Different Angle (part of "West Side Extraordinary")
The unique, sloping shape of the VIA 57 West building is formed from cast-in-place concrete from the single, partial basement level up to the structure's 34th floor; braced galvanized steel framing completes...

Fast Forward: Supertall Timber
At 350 m tall, this supertower would be three times the height of the California Redwoods and boast a structural system that is 90 percent wood....

Ready, Set, Launch
The replacement of a Warren through-truss bridge with a new structure similar in appearance over a very busy, 23-track rail yard in Minneapolis required prefabrication of steel trusses and an innovative...

Pro Bono Solar Project Restores Power to Puerto Rican Shelters

A New Light
Louvre Abu Dhabi was designed by Ateliers Jean Nouvel to resemble a group of islands at sea topped by a shallow dome that appears to float above. BuroHappold Engineering first created water-resistant basements...

Infrastructure Solutions: For Dams, Safety Comes First
Because the bulk of dams in the United States were built before this century, they are particularly plagued by aging infrastructure. Over the generations, the goal of those working on dams has moved from...

Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...

What's New in Geo? The Future of Numerical Geo-Modeling: Is 3D Here to Stay?!
Application of soil mechanics in engineering practice has undergone remarkable changes over the past 50 years as a result of developments in computer technology. Each improvement in computing capability,...

Borehole Geophysics: Tools to Characterize Rock Properties
Effective design and construction in rock requires characterization of the engineering properties of the rock mass, as well as any associated geological features such as joints, faults, and bedding planes....

Guidelines for Construction Vibrations: How Much Rattle is Too Much?
The study of construction/blast-related ground vibrations on structures, people, and objects is a surprisingly diverse field. Vibration sources vary from blasting, all types of construction equipment,...
