In late May of 2018, a severe thunderstorm dropped nearly 4” of rain on Raleigh in less than 2 hours. On Newton Road in North Raleigh, the flash flooding caused not only the failure of a twin 72” CMP culvert, but also an active 12” water main. CCI crews responded on an emergency call from the City to repair the water main and once complete, consulted with Raleigh’s Stormwater Department on the best course of action moving forward. Utilizing a Design-Build approach, we were able to expedite the design process and begin construction on the pipe replacement within 3 days from the original failure. The outdated corrugated metal pipes were replaced with a 9x6’ precast concrete box culvert that utilized Stone Strong block retaining walls at both upstream and downstream inverts. Material selection was critical on this project as lead time, installation and cost were all crucial factors. CCI was able to have Newton Road paved and re-opened to regular traffic in 63 days, over a month sooner than projected. Key subcontractors and suppliers included Summit Coastal, Marvel Engineering, Puryear Transport, Fences Unlimited, Patriot Concrete, Raleigh Paving and Carolina Guardrail. In addition to those contractors, this project could not have been a success without the assistance and cooperation of the City of Raleigh Public Utilities & Stormwater Departments, HDR Engineering, Froehling & Robertson and CH Engineering.
