Combined Interceptor Rehabilitation—Large-Diameter Sewer Presents Large Obstacles and Great Opportunity for North Charleston Sewer District

摘要

The success of the project, despite the difficult aspects of the site and the work completed can be attributed to the spirit of teamwork demonstrably applied during every stage of the project. The teamwork began with the relationship between the NCSD (Owner) and WK Dickson (Engineering Consultant), who have undertaken numerous challenging projects involving their collection system over the past several years. These projects require early planning, an intimate familiarity with the route of the host pipe and alternative for the bypass in the design and construction. Adjustments and field revisions on the fly are the norm, rather than the exception. The CIPP rehabilitation of other large diameter sections of the Cooper Interceptor served as training for the Combined Interceptor. The railway and roadway crossings were large obstacles, but not unique nor new to the design team. The initial planning by engineers from the NCSD and WK Dickson along with the feasibility analysis by Jacobs Engineering Group's (Sub Consultant) sewer rehabilitation specialist, Stephen Lindsey, gave the confidence that the project would be successful. Mr. Lindsey also performed resident project representation services, interacting, coordinating and observing operations by the Contractor throughout the rehabilitation construction phase. The affected property owners and regulatory agencies bought in and assisted as they could to facilitate finalization of the plans, permits, and regulatory agreements to allow the project to get underway. Lastly, the contractor joined the project with a cooperative, team-oriented approach and proceeded to construct the project in an efficient and professional manner. SAK demonstrated their desire to accept the challenges and execute the project. The contractor with their subcontractors and the other participants and stakeholders pulled together with cooperative efforts to complete this rather large and complex project.
