Autodesk Vice President Jim Lynch suggests the US should look to the UK and other countries for examples of how to push infrastructure initiatives and reduce costs. The UK has integrated building information modeling into the design and construction process, and that effort has saved $1 billion over six years.
Building information modeling is playing a key role in the design and construction of an 11.2-mile tunnel in Sweden. The effort has been a learning process, as BIM had never been used in Sweden's capital city at this scale.
Mass timber structures are getting more attention from architects and builders, and research is revealing a variety of advantages. One study shows timber floor structures are capable of sustaining loads well beyond design specifications, and another predicts significant savings from prefabrication of hybrid steel/timber structures.
The largest continuous concrete placement in China's bridge construction history was completed on a road-rail bridge that connects Shanghai and Nantong. Workers placed 70,700 cubic yards of concrete and used 8,179 tons of steel bars.
Virtual reality -- "an interactive, immersive visualization tool that can be used to construct highly interactive scenes for presentations, public outreach, planning and design" -- is making inroads in the building industry. This article explains how some state departments of transportation are using it and why use could increase over time.
RCAM Technologies plans to develop 3D-printed concrete turbine towers with the help of a $1.25 million grant from the California Energy Commission. RCAM would focus on the lower half of a 460- to 558-foot tower using a 3D printer and robotic arm on-site.
AeroAggregates is collecting curbside recycled glass and transforming it into lightweight foamed-glass aggregate that can be used in construction projects. The material is durable and has insulating properties.
One way to build teamwork is by clearly defining what success and respect look like. "When we have problems with somebody gossiping, or someone being disrespectful to a superior or a subordinate, or a peer, it is swarmed on and dealt with," says John Duffy, CEO of 3Cinteractive.
