Description
The Pennsylvania Department of Transportation (PennDOT) is seeking a contractor to repair a pipe culvert on SR 4009 through the installation of a Polyvinyl Chloride (PVC) pipe culvert liner. The project includes determining the necessary diameter and liner thickness, constructing access and working areas, dewatering and flushing the pipe, installing the liner, and filling the annular space with grout. The contractor will also be responsible for replacing existing pavement, curb, and sidewalk, as needed, and maintaining traffic control. The project is expected to last for 1 year. Key considerations for the contractor include ensuring the annular space is completely filled with grout, maintaining consistent spacing around the liner pipe, and following PennDOT's Project Manager's guidance on resolving any obstructions found during the project.
• The project requires the contractor to determine the necessary diameter and liner thickness based on depth, diameter, shape, traffic loading, groundwater pressures, and condition of the pipe segment.
• The contractor must ensure calculations are prepared and stamped by a professional engineer or manufacturer's specifications.
• The contractor is responsible for constructing access and working areas, dewatering and flushing the pipe, and installing the liner pipe.
• The contractor must fill the annular space between the existing pipe and the liner pipe with grout and patch holes and fill voids as required by PennDOT's Project Manager.
• The contractor is responsible for replacing existing pavement, curb, and sidewalk, as needed, and maintaining traffic control.
