Council contractors have to report back on the quantity of work they have carried out, the materials they used (types and quantities), how it got to site, what fuel was used to get it to site, the equipment and fuel used needed on site, and treatment of any waste created.
Details are gathered to help build a
Accurate, continuous monitoring of nitrogen dioxide and other gases in humid environments is now possible, thanks to a new water-resistant gas sensor developed by Huanyu “Larry” Cheng, the James L. Henderson Jr. Memorial Associate Professor of Engineering Science and Mechanics, and his team.
The sensor detects nitrogen dioxide in breath, the concentration of which may indicate potential pulmonary diseases, or
In July 2022, the U.S. Postal Service announced a revision to its Supplemental Environmental Impact Statement for its Next Generation Delivery Vehicles (NGDVs) in which 50% of its newly purchased NGDVs will be electric vehicles. The Postal Service says that this change will reflect route optimization, network refinements and financial improvements to its delivery vehicle requirement strategy.

Contractors face many challenges running their businesses today, including employee retention, supply chain concerns and more. But there are mixed answers when identifying their biggest concern.
According to the results of a survey released in July 2022 by frontline digital workplace WorkJam, employee shortages and turnover are more worrying for leaders than supply chain issues. Forty-eight percent of executives from
Buried high-voltage direct current (HVDC) lines in the rights-of-way along highways, waterways and railroad tracks have the potential for carrying more renewable energy cross-country more reliably than overhead power lines. There are challenges, but there are also incentives to make it worthwhile.
To encourage the development of “Clean Energy and Connectivity” projects along highways to expand and modernize the grid,
A team of researchers at the University of Massachusetts Amherst and the Georgia Institute of Technology has 3D printed a dual-phase, nanostructured high-entropy alloy that exceeds the strength and ductility of other state-of-the-art additively manufactured materials, which could lead to higher-performance components for applications in aerospace, medicine, energy and transportation. The work, led by Wen Chen, assistant professor of mechanical … Read More
