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...

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...

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...

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...

Zeroing In
Across the United States, primary and secondary school buildings are leading the way in the so-called zero-energy movement, in which structures are designed to generate at least as much energy as they...

Step by Step
The Angus L. Macdonald Bridge has fully reopened after the completion of its “Big Lift” project in Nova Scotia, Canada. The endeavor involved replacing the entire suspended span and all the hangers of...

NTSB Issues Preliminary Report on Florida Bridge Collapse (part of Infrastructure Solutions: Bridges Move Forward)
In late May, the National Transportation Safety Board (NTSB) released its preliminary report about the March 15 structural failure and collapose of a partially-constructed pedestrian bridge in Miami....

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...

A Preliminary Case for the Existence of Hurricane Alleys in the Gulf of Mexico
A review of hurricance intensity in the Gulf of Mexico suggests there are two alleys where hurricanes are roughly 20% more intense than elsewhere. This paper develops a physical basis for the alleys using...

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...

Where Geosynthetics Meet Mining Geotechnics: Part of the Mining Engineer's Toolbox
From enhancing stability to providing environmental containment, geosynthetic materials play an important role in mining projects and geotechnics in general. While often overlooked, advancements in geosynthetic...

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,...

Rock Glue Gets the Job Done: Reducing Rockfall Hazards along the G.W. Parkway
After a large rockfall damaged the road and disrupted traffic along the George Washington Memorial Parkway in 2002, the National Park Service was looking for solutions to stabilize the slope against additional...

Photogrammetry for Rock Engineering: A Snapshot of State-of-the-Art Rock Mapping
Generally speaking, photogrammetry is the science of turning photographs into 3D models. While flashy advertisements may convey the idea that it's as simple as pushing a button (e.g., on a drone remote)...
