Technology Briefs: 3-D Printers Build Model Cities for Wind-Tunnel Tests

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...

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....

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...

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,...

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

Next Step: Delegate, Network, and Ask for What You Want
Justin Siegrist, P.E., M.ASCE, is the hydraulic modeling lead in the Cincinnati office of Wade Trim. His advice to young engineers: delegate, network, and ask for what you want....

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...

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,...

Fast Forward: Around the Bend
An architecture firm envisions an inverted U-shaped tower in New York City that would outstrip the height of current megatall structures and replace it with length....

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...

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)...
