Deflection Testing. The Owner shall complete a deflection test for all new flexible storm sewers at least thirty (30) calendar days after backfilling but prior to paving. Pipe segments failing the deflection test shall be removed and replaced. Mandrel testing and laser profiling performed in accordance with OPSS.MUNI 438 and OPSS.MUNI 434, respectively, are acceptable tests for pipe deflection testing. Equipment used to perform mandrel tests shall be specifically designed for the pipe material being tested.
Deflection Testing. Utility Owner may require deflection tests utilizing a mandrel to be performed on flexible gravity sewer pipes. Deflection tests shall be conducted after the final backfill has been in place to permit stabilization of the soil-pipe system and follow the requirements of The Facility Owner’s Standard Specifications. No mechanical pulling devices shall be used. All pipes not passing this mandrel shall be re-laid or replaced by the Contractor at no additional cost to GDOT or Utility Owner.
Deflection Testing. Delete Section 679.3 (c) Equipment. Revise as follows:
Deflection Testing. (a) Leachate transit pipe shall be tested for deflection using a rigid mandrel sized to pass a maximum deflection (deformation of the pipe diameter) of 5%. No allowance shall be made for pipe wall thickness tolerances or out of round due to heat, shipping, or other external cause.
