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,...

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...

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...

Safer in Seattle
Constructed in the early 1900s, the Elliott Bay Seawall, in Seattle, protects the city’s downtown waterfront from the erosive forces of Puget Sound and Elliott Bay. Because of its deteriorating condition...

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...

Dry Dams in the Desert: Chasing Land Subsidence and Earth Fissures with Geophysics
Homogenous embankment dam flood retention structures (FRSs) were built throughout central Arizona desert basins in the mid-twentieth century to protect mostly agricultural lands and military installations...

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...

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...

Infrastructure Solutions: Help for Highways
In recent decades, America’s highways have received inadequate funding despite experiencing substantial increases in use. This combination has resulted in growing congestion, especially in urban areas,...

First Person: Lucky Horseshoe
A $798-million Dallas highway project improved traffic flow into and out of the city’s downtown. The new “Horseshoe” interchange corrected the traffic bottlenecks and safety concerns of the original design...

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...

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...

Paleoflood Analyses For Dam and Levee Safety Assessments: Was that Really the "500-Year Flood"?
What is paleoflood hydrology? How are paleofloods analyzed? What are common paleoflood results? What are the implications of paleoflood analyses?...

Calibration of Jackup Leg Foundation Model Using Full-Scale Structural Measurements
The fitness of jack-up rigs to operate in varying water depths and weather conditions is determined by "site-specific" structural assessments. These assessments are conducted by a wide range of companies...

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...

When Old Meets New: Railway Geotechnics and Remote Sensing
Railroad track, like any other built structure, relies on a foundation of geomaterials for support. In its most basal form, the railway track is quite simple: steel load-bearing members (rails) supported...

When Things Became Muddy: TVA's Response to Seepage Discharge at Boone Dam
In October 2014, the Tennessee Valley Authority (TVA) profited from investments in a robust dam safety program. This profit did not come in the form of money, but more importantly in the protection of...

Dam Safety Management Using Risk-Informed Decision-Making Methods: A Powerful Tool or an Unnecessary Venture?
This article discusses design standards, safety methods, and risk-informed decision-making methods for dams....

The Case for Tolerable Risk Guidelines to Manage Flood Risk: Nature Bats Last
Since ancient times, people have used levees to reduce flood risk. We have built over 30,000 miles of levees in the U.S., largely on the belief that levies will unconditionally protect people who live...
