Centrifugally cast concrete pipe (CCCP) is an established trenchless rehabilitation solution for large diameter sewers and culverts and is gaining ground with state departments of transportation (DOTs), which are traditionally conservative when adopting new technology. A recent culvert rehabilitation project, let by the Colorado Department of Transportation (CDOT) is groundbreaking in this regard. “There were a total of 10 large culverts in this particular project (CDOT #20158R, Region One, covering the Greater Denver Metro and Central Colorado area) and seven seemed like good candidates for CCCP,” says Paul Snyder, president of American West Construction LLC (AWC). “And since specifications were written in a way that permitted CCCP, we went for it — it’s the largest CentriPipe project in Colorado, so far.”
