Nightmare at the museum
When the Washington, D.C., area experienced severe flooding, several buildings on and around Constitution Avenue suffered significant water damage. One of those buildings was the Smithsonian Institution’s National Museum of Natural History. Its basement received as much as 4 inches of water. While the basement was previously used to house zoology, botany, and entomology collections, a plan to relocate the Office of Facilities Engineering and Operations to the basement made it even more crucial to find the source of water infiltration. The Smithsonian Institution commissioned AECOM to research, analyze existing conditions, and implement the design to mitigate future water infiltration. To read the full article, click here.
Stormwater system solves site challengesfor the Bahamas airport
What do you do when you’re presented with flat terrain and a high groundwater level when trying to implement a new stormwater management system? Go underground. Engineers were faced with these issues when designing a stormwater management system for the Lynden Pindling International Airport in the Bahamas. Their solution came in the form of two underground systems. The CULTEC Recharger 180 HD unit is 36 inches wide by 20.5 inches high with a chamber storage capacity of 3.45 cubic feet per linear foot. It provided the largest storage volume and was the best fit in the given depth-restriction scenario. To read the entire article, visit http://bit.ly/aPdeSa.
Bringing new life to the I-5 Willamette River Bridge
In replacing the Willamette River Bridge, the Oregon Department of Transportation (ODOT) is taking extra steps to ensure it’s as environmentally friendly as possible. ODOT’s challenge was to design and construct the bridge within the physical constraints of the river and adjacent park lands, while also meeting community needs. To accomplish this, ODOT collaborated with area residents, community stakeholders, and public agencies; prepared an environmental assessment; developed a unique set of programmatic permits based on the use of environmental performance standards to guide design and construction activities; carefully planned the original bridge demolition; and protected its surrounding habitats.
