Aluminized Steel and StormFilter Manage Stormwater
A combination of underground storage and treatment was used to meet stormwater management goals at the new Alliance Hospitality Residence Inn. For the storage component, engineers selected a corrugated metal pipe detention system made from perforated Aluminized Steel Type 2. To meet the water quality goal of 80% TSS removal, engineers specified a Stormwater Management StormFilter utilizing 18 cartridges with a removable grate for easier long-term access.
During a project to extend Clinton Keith Road an additional two miles, a wildlife crossing was needed. As the best solution, twoBEBO® Bridge Concrete Arch Systems were selected to provide a safe crossing for the endangered Quino checkerspot butterfly above and motorists below.
During a routine inspection, a reinforced concrete pipe drainage culvert was found to be structurally deficient with cracking, spalling and joint failures occurring throughout the run, the pipe was relined efficiently and successfully with DuroMaxx® SRPE liner pipe.
Washington State Department of Transportation addresses a stream crossing / fish habitat problem by installing a high quality, lower cost BEBO® Bridge Concrete Arch System and a Keystone Compac® II structural wall system.
One of the most frequently asked questions is: "Will this alternate pipe solution convey the same amount of flow that's shown on these set of plans?" And the same tired response is: "Well, that depends." Why does it always have to depend on something? Just give me an answer: yes or no? As an engineer, it has been beaten into your head that it takes a handful of known variables to solve an equation. Some equations are simpler than others and will give you a ballpark estimate, while other equations are more complex and give you a more accurate result.
What's Happening Inside My High Performance Biofiltration System?
An appropriately designed and manufactured high performance biofiltration system combines the benefits of natural biofiltration with the reliable and predictable performance of an engineered system. Each high performance biofiltration system utilizes a multifaceted approach including physical, chemical and biological processes to capture, immobilize and treat harmful pollutants, while also encouraging low impact development practices by treating smaller drainage areas at the source.
When an oversized vehicular tunnel was needed at the Talladega Superspeedway in Alabama, a CON/SPAN B-Series Bridge System was selected as the best solution. The tunnel was just one component of the $50 million 2019 Transformation Infield Project to celebrate the track's 50th Anniversary.
