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.
An Energy Storage Project Gains Traction
Pumped hydro but without the water is the essence of an energy storage project that has moved one step closer to being built.
U.S. Roofs in Good Repair Can Handle the Weight of PV: Sandia
Dwyer says engineers doing rooftop structural analysis often calculate stresses on the basis of an individual beam, rafter or truss.
Simple Building Retrofit Can Reduce Sway from Earthquakes
The device can be placed anywhere internal or external fluids interact with physical structures and subsequently be tuned to the frequency at which a building moves.
San Francisco Seawall Requires $3 Billion for Quake-Proofing
Weak soils below the seawall are highly susceptible to lateral spreading along its entire three-mile length, increasing the expected damage to structures and infrastructure adjacent to the seawall.
Mushrooms as a Building Insulation Alternative?
Mushroom-based building insulation is grown rather than manufactured.
Inflatable Habitat "BEAMed" Up to the ISS
Expandable habitats are designed to take up less room on a rocket, but provide greater volume for living and working in space once expanded.
One of the World's Largest Timber Towers Proposed for London
The use of timber as a structural material in tall buildings is an area of emerging interest for its variety of potential benefits, the most obvious being that it is a renewable resource.
"PowerWindows" Convert Light into Electricity
PowerWindows collect reflected light, transport it, and convert it at solar cell strips inside the window frame.
Windows Are the Key to Energy Efficiency: Study
The study related energy usage in typical households to the consumer's actual trends and habits in consuming energy.
Transparent Wood Material Developed for Buildings, Solar Cells
The KTH project introduces a way to use optically transparent wood on a large scale.
Virtual Reality, 3D Printing May Improve Hospital Design
Virtual reality technology and 3D printing are being applied to design hospitals that better meet patient needs.
