(1) If less than 20 yd3/ day, the engineer may waive air testing if inspection is not available and producer has exhibited consistency in prior placements (3) Sampling and testing rate if no other concrete supplied. Use structural or paving test results to cover non structural concrete items. (4) If less than 500 yd3 per day / intermittent construction continues for more than two weeks, obtain verification samples weekly and test 20% of the samples obtained. |
