Deflection Testing Sample Clauses
The Deflection Testing clause establishes requirements for measuring the amount of bending or displacement in a structural element under load. Typically, this clause specifies the testing procedures, acceptable limits of deflection, and the conditions under which the tests must be performed, such as during construction or after installation. By setting clear standards for deflection, the clause ensures that structures maintain their integrity and safety, preventing excessive movement that could lead to damage or failure.
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 Plans and Special Provisions. 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.
(b) The inspection shall be conducted no earlier than thirty (30) calendar days after the backfill has been placed to final grade, and provided in the opinion of the Contract Administrator that sufficient water densification or rainfall has occurred to thoroughly settle the soil throughout the entire trench depth. If densification cannot be achieved in the time after installation of the pipe and backfill prior to the project completion date, then the mandrel size shall be increased to pass a maximum deflection of 4%.
(c) The mandrel shall be carefully pulled through the sewer by the Contractor. Any sections of sewer that does not allow the mandrel to pass shall be considered to have failed the deflection test and shall be uncovered, repaired or replaced at the Contractor’s sole expense and the section tested again.
