Common use of Laboratory Tests Clause in Contracts

Laboratory Tests. The Contractor shall take one litre sample from the discharge point of the dredging line and analyse and report the particle grading by weight not later than the following day. The Contractor shall carry out these tests every 72 hours. Should any test result indicate non-compliance with the fill specifications, they shall be reported to the Engineer's Representative immediately. The Contractor shall store the remaining portions of the samples and mark all test samples to indicate the date and location from which they were dredged. When dredging operations are in progress, if the Contractor notice any abrupt change within 1.0 m of reaching the theoretical boundary between sand and clay (as defined by the Client), the Contractor shall inform the Engineer's Representative (or suitably delegated representative) immediately, and perform the above mentioned visual and laboratory tests every 12 hrs. If the Engineer's Representative (or suitably delegated representative) considers that the visual check clearly indicates a clay material, the Contractor shall pump the dredged material in the on land clay disposal area. If the Engineer's Representative (or suitably delegated representative) considers that the visual check clearly indicates a sand material, the Contractor shall pump the dredged material to the onland sand reclamation, in conformity with the fill requirements. If the Engineer's Representative (or suitably delegated representative) considers that the visual check clearly indicates a clay material which is pumped in the on land for sand reclamation, the Engineer's Representative may then require that further sampling and testing be done, or he may instruct the immediate cessation of dredging for hydraulic fill from the area being used, and indicate a new area for dredging.

Laboratory Tests. The Contractor shall take one litre sample from the discharge point of the dredging line and analyse and report the particle grading by weight not later than the following day. The Contractor contractor shall carry out these tests every 72 hoursthrice at each location – one at beginning, one at end and one intermediate during dredging at each location. Should any test result indicate non-compliance with the fill specifications, they shall be reported to the Engineer's Representative immediately. The Contractor shall store the remaining portions of the samples and mark all test samples to indicate the date and location from which they were dredged.
