Field quality control testing including, but not limited to, Total Solids (TS) testing of <br /> biosolids. <br /> 1.2 PERCENT SOLIDS TESTING <br /> A. Each load of dewatered biosolids solids ready for loading and weighing shall be <br /> sampled and tested by the Contractor to verify the minimum TS of 28% prior to loading <br /> the material and hauling over the scale. <br /> B. Contractor shall also provide the City with a sample from each load to be hauled over <br /> the scale. <br /> C. Each sample provided for City testing shall be a composite sample made up of a <br /> minimum of three (3) grab samples from each truckload. These samples shall be <br /> collected by the Contractor with the samples provided to the City on a daily basis. The <br /> City may also collect independent samples at the discretion of the City's Project <br /> Manager. <br /> D. A sample container shall consist of hard plastic or glass with a secured lid and each <br /> sample shall contain a minimum of three ounces (85 grams) of dewatered biosolids. <br /> Each sample shall be labeled with the date and time that the sample was taken. <br /> E. Samples shall be collected during the truck loading process in a manner approved by <br /> the City's Project Manager and shall be representative of the material ready to be <br /> weighed and transported to the applicable area on the biosolids pad. <br /> F. Samples shall be analyzed by the City at no cost to the Contractor. The Contractor <br /> may perform duplicate solids analysis, at the Contractor's expense. <br /> G. Failure of any tested material to meet the 28% TS requirement prior to loading and <br /> weighing will result in the material being reprocessed until the material meets the <br /> ' required minimum of 28% solids. Reprocessing of any materials shall be at the <br /> Contractor's expense. <br /> H. Failure of any material to meet the 28% TS as tested by the City will result in the load <br /> of material being ineligible for payment. <br /> I. City will perform a combination of onsite testing and testing of samples in the City's lab <br /> to determine the TS% in each load. <br /> END OF SECTION 01 4523 <br /> 01 4523 - 1 MATERIAL TESTING <br /> I <br />
