Corrugated Metal Pipe and Vortechs Provide Stormwater Detention System
When a 22-acre property previously used for illegal dumping was transformed into an upscale apartment complex, a stormwater detention system was needed. The design team specified corrugated metal pipe for underground storage, with the water being pretreated by a Vortechs hydrodynamic separator.
After the existing structure was damaged by Hurricane Katrina, aCON/SPAN® O-Series® Bridge System was selected as the best bridge replacement option because the clear span was able to provide a waterway area sufficient enough to discourage future debris buildup and flooding.
Following unprecedented hurricane seasons, a utility company strengthened their electric grid by replacing outdated utility poles and reinforcing the new ones with CORLIX® pipe.
When It Comes to Safety Without a Zero Goal and Vision, Our Focus is Skewed
Recently, I was watching a safety leadership discussion. The discussion was engaging and designed to compel the audience to make safety a priority. In the safety speech, the keynote speaker asked the audience, how many people here think an Accident Free Workplace is possible? Only about 10% raised their hand. Why do you think that was? The answer was simple. We are human, and humans make mistakes. In the workplace, it is that one critical action where a mistake can cost you your life.
Examining Stone Void Space Part 2: How to Minimize the Reliance on Stone Voids for Storage
In part one of this series, we examined new research that showed the generally accepted number of 40% porosity (hereby referred to as “stone voids” and “void space”) within the stone backfill as available storage might not be a reliable number. To obtain a 96% reliability in stone storage, 36% stone void storage should be considered in the design. This has significant implications as stormwater detention systems often include a large portion of the storage volume within the voids of the backfill material. Therefore, the end goal for engineers should be to minimize the reliance on stone voids for storage which also reduces downstream concerns.
As the world evolves, civil engineering needs to evolve with it. That evolution must begin with education. In this episode of ASCE Interchange, Kevin Hall, professor of infrastructure engineering at the University of Arkansas and the chair of ASCE’s 2019 Civil Engineering Education Summit Program Committee, discusses the future of civil engineering education.
DuroMaxx Steel Reinforced Polyethylene Pipe Approved By AREMA
Contech's DuroMaxx®steel reinforced polyethylene (SRPE) pipeavailable in diameters as large as 120” was recently approved by the American Railway Engineering and Maintenance-of-Way Association (AREMA) for both direct-bury and reline applications.
