Lot Testing 5.10.1 Conformance of compaction will be based on lots. Give each lot a lot number. Number the lots using a logical system. Maintain a register of all lots and lot numbers. Include the location of each lot on the lot register. Provide a copy of the lot register to the Superintendent upon request. Lots defined by the contractor must be clearly marked out on the construction site. Lots of work will be selected by the Contractor, based upon: - A lot will represent no more than one shift's production. - A lot will be continuous and will have been brought to completion at the same time. - A lot will be composed of essentially homogeneous material with no distinct changes in attribute values. Each lot will be subject to conformance testing in accordance with NTCP 102.1. Defective sections will be excluded from the lot to be tested and identified as a separate lot, and will also be subjected to lot testing. Quality of the lot will be judged as conformance or non-conformance of each lot. This will be based on all tests conducted on the lot in accordance with NTCP 102.1.
