SSCI Job Timeline: Culvert Construction - SSCI Environmental

SSCI provided maintenance activities to a damaged culvert owned by an HOA located in Dickinson, Texas (Site) where existing articulated concrete blocks (ACBs) were uplifted and separated during a Hurricane Harvey.  This caused the subgrade to be eroded and a large hole to form at the base of the culvert. SSCI was able to mobilize quickly and efficiently to solve the problem.  The work involved designing a new, more effective culvert layout that would significantly reduce erosion during large rain events.

The following construction services were also completed during the remediation:

• Pumping of standing water in the washout area;
• Replacement of soil and re-grading of subgrade slope;
• Salvage and placement of ACBs onto subgrade;
• Placement of inlet and piping;
• Paving of high-flow areas in the culvert to reduce erosion.

A final post-repair visit to the Site was conducted to ensure the satisfaction of the HOA and replace ACBs in an aesthetically pleasing pattern. The HOA continues to work with SSCI on other detention pond, erosion, and maintenance activities.  SSCI finished the work ahead of schedule even after being impacted by weather-related delays.
