Wetlands Worth their Weight
Monitoring, Managing and Protecting Ecological Powerhouses “Wetland” is a generic term covering a wide variety of habitats that are wet for at least some period of time each year, have vegetation, and have soils that are saturated long enough during the growing season to produce oxygen-deficient conditions. Although they can vary tremendously depending on climate and topography, all wetlands promote the growth of different types of microbial, plant and animal communities. Wetlands attenuat...

Oregon Preparing for Export: Assessing the Seismic Challenges of a Liquified Natural Gas Plant
In the international port of Coos Bay, Ore., construction will begin in late 2016 on a liquefied natural gas (LNG) export terminal that will be the largest private construction project in the state’s history. The bay is separated from the ocean by a tongue of land varying in width from 0.3 miles at the entrance to 1.9 miles at Jordan Cove, where the plant will be built. The facility requires access to the ocean for the deep draft vessels that will move its cargo to customers across the Pacifi...

Better in 3D: How 3D Modeling Helped Overcome Complexity in Building the Longest Cable-stayed Bridge in Africa
When Morocco’s highway company, Autoroutes Du Maroc (ADM), undertook a highway bypass project in 2010 that would cross the Bouregreg River, they could have built a traditional viaduct. Instead, they set out to construct Africa’s longest and tallest cable-stayed bridge. The resulting project presented unique and complex challenges that called for innovative solutions. The Bouregreg River runs from the Atlas Mountains to the Atlantic coast between the cities of Rabat and Salé in western Morocco...
Oslo Airport Expansion: Open BIM Approach Improves Project Efficiency
By Bjørnar Markussen Avinor Oslo Airport plays a crucial role as the hub of Norway’s aviation system, serving domestic and international passenger and cargo flights. Upon opening in 1998, the new airport boosted its capacity to handle 17 million passengers annually, but less than a decade later, it was clear that demand would soon outgrow capacity. It was then that the board of Avinor, owner of the airport, began planning a major expansion in close collaboration with airlines and handling...
Crystal River Works to Save Manatees and the Local Economy
Crystal River, Fla., is the self-proclaimed “home of the manatee.” An estimated 300,000 tourists visit Crystal River each year, many of them to see and experience the graceful manatees, the giant herbivores often referred to as “sea cows.” For a town with a population of only 3,100, such an influx of people represents an important economic boon for everyone in the area. The geography and ecology of the Crystal River region is perfect for manatees, which often weigh up to 1,300 pounds. Because...
Ordnance Survey Ireland Creates an Authoritative National Spatial Data Infrastructure
Ordnance Survey Ireland (OSi), Ireland’s national mapping agency, has developed a standardized, authoritative digital referencing framework that enables consistent referencing and integration of national data related to location. This visionary framework, known as Prime2, allows GIS data users to accurately integrate and use multiple data sources for improved analysis and decision making, resource optimization, and efficiency gains. More than six years in the making, the new spatial data refe...
Bridging the Gap Between Inspections and Decisions
Bridge safety hasn’t always been top of mind for legislators in the United States. The impetus for creating standards and collecting information on how structurally sound the bridges in this country was the collapse of the Silver Bridge in 1967, which spanned the Ohio River between Point Pleasant, WV, and Kanauga, Ohio. The tragedy claimed the lives of 46 people and caused the federal government to quickly mandate regular bridge inspections through the National Bridge Inspection Standards (NBIS)...
Self-Propelled Bridges: Offsite Superstructure Construction Reduces Interruption
The Wisconsin Department of Transportation (WisDOT) is in the midst of a major project to rebuild the I-94 North-South freeway, one of the state’s most frequently used roadways. The freeway is being widened to eight lanes from the Wisconsin/Illinois border to Milwaukee, with new bridges and interchanges along the full 35-mile stretch. In addition to this freeway work, frontage roads and main arteries are being reconstructed and moved. In total, 17 interchanges are being completely redesigned,...
