In applying this requirement to prestressed members, the strength tests performed on all similar members, such as beams, shall be grouped together for purposes of counting the number of tests available. The abutments shall be considered one structural element, and the diaphragms shall be considered one structural element.

If concrete strength tests fail to meet the requirements of this specification, the CO may order the Contractor to have a testing laboratory that is acceptable to the Forest Service take and test core samples of questionable concrete, in accordance with AASHTO T-24.

The COR may order all low-strength concrete removed and replaced if core strengths are below specified strengths. All costs connected with concrete coring and removal and replacement of concrete that fails to meet these requirements shall be borne by the Contractor.
