Boston Dynamics' four-legged Spot robot can autonomously follow a human leader through a construction site using software from Trimble and Piaggio Fast Forward. The robot can then retrace the original route and adapt on its own as surroundings change.
Officials have closed mile 11 on Alaska's Hatcher Pass Road due to a persistent avalanche threat. The state Transportation Department's decision came after five avalanches blocked the road during Easter weekend, and officials plan for a helicopter to drop explosives in a bid to stabilize the situation.
The Associated General Contractors of America is assembling political allies in opposition to the Protecting the Right to Organize Act passed by the House last month. Many senators oppose the legislation, which may face a filibuster that would effectively kill the bill.
A vehicle-miles-traveled fee to be implemented on a national scale is supported by more than 30 construction, engineering, transportation and other groups. The Associated General Contractors of America joins others in the coalition calling for a VMT to "replace all current motor fuel taxes and fees" as gas tax revenues for transportation fall.
The poor condition of Louisiana's roads costs drivers $7.6 billion annually in additional congestion, vehicle operating costs and crashes, according to The Road Information Program. Ken Naquin, CEO of the Louisiana Association of General Contractors, urges state lawmakers to take action.
There are at least four breaches to a levee system that could result in floods in Hidalgo County, Texas, during hurricane season, said county Judge Richard Cortez. The breaches formed during construction of a wall on the border with Mexico and were never repaired when construction stopped, Cortez said.
The combination of fiber-optic sensors in a fiber-reinforced polymer bridge deck in north central Tennessee could provide a sustainable solution that can be applied to many other deficient bridges in rural areas. The FRP deck is said to be highly corrosion-resistant.
SmartTake: One of the biggest barriers to greater adoption of FRP in bridges has been a dearth of durability data, says Dr. Dayakar Penumadu. This project is helping take down those barriers.
Infrastructure can complement and increase biodiversity and natural capital while creating carbon sinks, writes Robert Spencer, director of sustainable development at AECOM. Nature-based solutions' higher costs, as compared to traditional infrastructure solutions, are justified based on the cost to the planet of doing nothing, as AECOM's Natural Capital Laboratory in Scotland demonstrates.
Associate professor Amanda Bao applies extensive bridge building experience and a focus on engagement to her civil engineering technology classes at the Rochester Institute of Technology. Bao says her goal with students is "to teach them how to think, how to solve a problem."
A system that incorporates four lasers and a depth camera may help detect impending problems in aging infrastructure when human monitoring is scarce. A South Korean study finds promise in the monitoring solution, which produces image homography to reveal surface damage on concrete structures.
