(a) Whenever there is reasonable doubt as to the stability or structural safety of a completed building or structure, or part thereof, for the intended use, the Building Commissioner may require a load test of the building unit or portion of the structure.
(b) Unless otherwise provided for in this Code, the structure under consideration shall be subjected to a superimposed load equal to two times the design live load which shall be left in position for a period of 24 hours. If during the test, or upon removal of the test load, the structure shows evidences of failure, the Building Commissioner shall order such reinforcement or modifications deemed necessary to insure adequacy of the structure for the rated capacity; or in lieu thereof, the Building Commissioner may determine the safe load capacity to which the structure shall be limited.
(c) The structure shall be considered to have successfully passed the test if the total deflection does not exceed the theoretical deflection computed by accepted engineering formulae, or if the total deflection exceeds the theoretical value, the structure shall be considered safe for the design load if it recovers 75 percent of the maximum deflection within 24 hours after removal of the test load.
