Case Study: Putting Green Infrastructure to Work

The blank slate of a new project can offer invaluable opportunities for innovative design and construction methods. The design and construction of the Water Replenishment District’s (WRD) Albert Robles Center for Water Recycling and Environmental Learning (ARC) (Figure 1) offered one such opportunity with regards to green infrastructure and stormwater management in particular. However, WRD has further maximized the reach of this green infrastructure by using it to demonstrate the benefits of low impact development to the public through the site’s educational features.

Perspective: The Equatorial Rainforest’s Role in Climate Change and Sea-Level Rise

There is no doubt that the global sea level is rising. The global mean sea level has risen 8 to 9 inches (21 to 24 cm) since 1880. The majority of that rise has occurred in the past 25 years.1 Climate change and the melting of glaciers and ice sheets are adding to the volume of water in the oceans1 but sedimentation also plays a role. One report demonstrates that sediment erosion and deposition, like ice growth and melt, produce significant changes in the Earth’s crustal elevation, gravity field, and rotation axis, all of which induce changes in sea level.2 Continue Reading

Western Sydney Airport Highlights Importance of Technology in Earthworks

The Western Sydney International (Nancy-Bird Walton) Airport (WSA) project is a rare greenfield opportunity for a new airport rather than a reconstruction or renovation of an existing airport. It is also one of the largest civil earthmoving projects in Australia’s history. The airport will open in late 2026 and is projected to serve up to 10 million domestic and international passengers annually. The overall design of the terminal and airport property brings together best practices to offer passengers and airlines an experience unrivalled among Australian airports. Continue Reading
