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.
Rebuilding Damaged Bridges ASAP
A new method may quickly restore structurally damaged support columns.
Infrastructure Needs $3.3 Trillion Over Next Decade: ASCE
Through 2025, planned investment is $1.8 trillion, leaving a $1.5 trillion gap.
Video: Your car’s roof rack may be eating into your mileage. Engineers use accelerated technique to replace a pair of bridges. This humanoid robot is diving for treasure.

Accelerated Bridge-Building Method Shortens Construction Time
The accelerated bridge-building methods will allow for completion of the overpasses one year earlier than would be possible using conventional construction techniques.
Synchronized Jack-Up System for Big Lifts
Engineering firm Enerpac says that it has created one of the world’s tallest multipoint jack-up systems.
New Type of Cement Is More Durable, More Sustainable
Production of cement for use in concrete is believed to be responsible for 5-8% of the global emissions of carbon dioxide—largely because so much concrete is used.
Video Tour of Seattle SR99 Tunnel Construction
The under-construction SR99 Seattle Alaskan Way Viaduct highway tunnel ranks as one of the most ambitious tunneling projects attempted in North America.
Tracked Crawler Carrier Rotates 360-Degrees
A rubber track crawler carrier introduced by Terramac includes a rotational dumping body.
A Faster Way to Fix Earthquake-Damaged Bridge Columns
A quicker process for fixing bridge columns involves creating concrete donuts known as “repairs” that are lined with a composite fiber material built around the top and bottom of each column.
Tracked Crawler Carrier Rotates 360-Degrees
A rubber track crawler carrier from Terramac boasts a rotational dumping body.
Good Engineer or Good Project Manager? Cost Considerations
Understanding if adequate funds have been allocated or if additional money is required that may hurt the project’s viability.
Study Shows Current Offshore Platforms Can Survive Sea Ice
The researchers concluded that it appears the current standard of practice cited in ISO 19906 is appropriate for guiding the construction of offshore platforms to survive the demands from sea ice.
High-Strength Steel Connectors Used to Absorb Seismic Shocks
Most steel frame construction welds together support beams cut from large plates. However, the resulting buildings are relatively rigid and vulnerable to damage and collapse in earthquakes.
Natural and Man-Made Structures Are Best Flood Defense: Study
A neighborhood-wide hybrid approach combining both nature-based features and human-made solutions proved most effective in protecting coastal areas from storm flooding.
San Francisco to Require Solar Panels on Smaller New Buildings
The new ordinance builds on state law by requiring the 15% of roof area that is already required to be “solar ready” to have either solar photovoltaic or solar water panels actually installed.
