Inside Switzerland's Gotthard Base Tunnel
The world’s longest train tunnel opened to passenger and freight traffic in early June. Here's how engineers built it.
The Need for Project Quality Management
The cost can be significant if no quality management program exists.
Clean Water, Big Price Tag
Water treatment infrastructure in the U.S. remains underfunded and underappreciated.
Intelligent Machine Control Helps Reduce Operator Error
Intelligent machine control technology may help a Komatsu tracked excavator minimize operator human error.
Designing More Durable Concrete
Today’s concrete is a random assemblage of crushed rocks and stones bound together by a cement paste.
Porosity in Parts Produced Via Laser Powder-Bed Fusion Explained
Using a custom-built microscope setup, a vacuum chamber and an ultra-high-speed camera, Matthews’ team observed the ejection of metal powder away from the laser during the melting process.
Robotically Fabricated Pavilion Takes Shape in London
The Elytra Filament Pavilion is a canopy of tightly woven carbon fiber cells created using a novel robotic production process.
3D-Printed Office Building Opens in Dubai
The full model took 17 days to print, after which the office was installed onsite in two days.
JC Penney Headquarters Building Uses Ice to Cut Energy Bills
By using the ice energy storage technology, JC Penney is able to flatten its electricity load profile and reduce energy consumption during peak demand periods.
Modified Cement Emits Light for Roadways, Buildings
A researcher has created a light-emitting product that has an estimated lifespan of 100 years.
Inertial Measurement Technology Could Aid Grade Control
Technology for bulldozers operates faster and more accurately than global positioning grade controls.
Daffodils Inspire Design of Stable Structures
Vortex shedding affects any elongated structure caught in wind or water currents, such as lampposts, high rises and the long vertical pipes used for drilling oil at sea.
Two Elevator Cabs, One Shaft: 40% More Capacity
Each twin elevator has its own major mechanical and electrical components but shares the same guide rails and landing doors in a single elevator shaft.
Siemens Wind Turbine Towers to Top 115 Meters
A feature of the tower system is the on-site match casting of annular precast tower segments, which eliminates the need to grout the joints between tower sections.
