Coring Clause Samples

Coring. If in the event coring must occur, and Provider approves such coring, an x-ray and supporting documents must be provided prior to coring.

Coring. Each well will be designed and drilled such that a suitable recovery of rotary core be recovered, preserved and tested. All core data, including but not limited to porosity, permeability, geochemical and geomechanical properties, shall be promptly shared between the Parties.

Coring. CONTRACTOR shall core at the depths which COMPANY shall specify and shall deliver all cores in COMPANY’S containers, properly labeled, to COMPANY and shall not allow any third person access to the cores or to the samples referred to in Article 15.8, or to any core or sample data, without COMPANY’S consent.

Coring. The Building structure has limitations on where any penetrations may occur. The Contractor shall x-ray/scan the area where the penetration is to occur. The Owner is to approve the penetration location after the completion of the x-ray/scanning and prior to coring. The Contractor is to properly protect the area below the penetration and is responsible for cleaning all debris. All such work is to be coordinated with the Owner. All cores are to be fire stopped per code. All existing cores not being reused are to be filled to match existing conditions. AFDOCS//21459967

Coring. The Engineer reserves the right to generate the random locations. If KDOT plans to generate the random locations, the Contractor will be notified before taking cores for thickness determination. (a) For mainline and other pavement subject to coring for pay adjustments for thickness, strength, and volume of permeability voids, take 2 core samples having a minimum diameter of 4 inches from a randomly selected site within each sublot. The first core is for thickness and compressive strength determination. The second core is for volume of permeable voids determination. The Contractor has the option of taking an additional core sample having a minimum diameter of 2 inches from a randomly selected site within each sublot for the purpose of making an early determination of the pavement thickness only. Select sites according to the approved QCP. Additionally, take 2 companion cores having a minimum diameter of 4 inches per each lot at a randomly selected site as designated by the Engineer. The first core is for thickness and compressive strength determination. The second core is for volume of permeable voids determination. Repair all core holes in a manner approved by the Engineer. Perform all coring for the purpose of determining strength and volume of permeable voids a minimum of 21 days after the pavement has been placed, and in time to determine 28-day compressive strengths and volume of permeable voids. Coring prior to the 21- day minimum will be permitted with approval of the Engineer, when opening to early traffic is desired. If the companion cores will be measured and tested by the MRC, the Engineer will deliver the companion cores to the MRC within 25 days after the pavement has been placed. No initial QC compressive strength data will be accepted for concrete paving that is more than 28 days of age, unless approved by the Engineer. (b) For all other PCCP subject to coring for pay adjustment, thickness only, define the lots prior to placement with the Engineer’s approval. After placement, randomly select each sublot location. Take 1 core sample having a minimum diameter of 2 inches. Repair all core holes in a manner approved by the Engineer. Coring may be performed at any time after all pavement in the lot has been placed.

Coring. 16.1 Contractor shall perform all cores into abutments, tunnel walls, manholes, handholes, and vaults by utilizing a core drill with a core type bit. Contractor shall drill a pilot hole prior to performing the core to verify the core’s location. Contractor shall core a hole that is not more than one half inch (1/2”) greater than the outside diameter of the conduit that is being placed through the core. Contractor shall seal the core utilizing a non- shrink grout. In addition, Contractor shall adhere to the specifications imposed by the owner of the facility being cored into. 16.2 Contractor shall perform all cores into buildings by utilizing a core drill with a core type bit. Contractor shall drill a pilot hole prior to performing the core to verify the core’s location. Contractor shall core a hole that is not more than two inches (2”) greater than the outside diameter of the conduit that is being place through the core. Contractor shall furnish and install a link seal on both ends of the core and tighten in a criss-cross fashion. In addition, Contractor shall adhere to the specifications imposed by the owner of the facility being cored into. 16.3 Contractor shall stub out conduit according to the NESC. 16.4 All clean up is the responsibility of the Contractor.
