| D. CERTIFICATION AND STOCKPILE INSPECTION: Vendor will maintain a minimum stockpile of one-hundred (100) cubic yards of material at all times. The Commission reserves the right to verify material availability at said stockpile. E. WEIGHING: All shipments will be accepted by weight. Shipments must be weighed by a licensed Public Weigh Master and accompanied by a Weigh Master's certificate. The scale used must be approved by the Department of Agriculture Bureau of Standard Weights and Measures, or tested and approved by a Scale Repair Service with testing capabilities with appropriate weights and procedures as contained in Scale Code NBS Handbook 44. Weights used to conduct tests must be certified to be within Class F tolerances. The Weigh Master's certificate must be in conformance with Pennsylvania Code Title 70. In addition a digital printer must be used if the source has that capability in its scale. The Commission reserves the right to have truck deliveries check weighed at independent weighing station. NOTE: Deliveries will only be accepted after a PTC employee has verified weighing of material with vendor's representative at vendor's location and has initialed weight slip. F. DELIVERY: Material shall be delivered to the Pennsylvania Turnpike Commission stockpiles as directed by the Pennsylvania Turnpike Commission District Superintendent. VENDOR MUST INFORM APPROPRIATE DISTRICT SUPERINTENDENT PRIOR TO START OF DELIVERY. Upon arrival at PTC stockpile, vendor's driver will be required to contact a PTC representative at that location for stockpile unloading instructions. Material will be unloaded in segregated stockpiles to await sampling. The contractor will furnish an original and two copies of the invoice. In cases where computerization required the vendor to retain the original copy, two copies of the delivery ticket will be acceptable; however, one of the copies must be stamped or indicated: "ORIGINAL DUE TO COMPUTERIZATION OR AUTOMATIC MACHINE ACCOUNTING" G. TESTING/SAMPLING: It will be necessary to test the material for moisture content when shipping to PTC stockpiles. Tests should be conducted in accordance with PTM No. 513 (Pennsylvania Test Method), except that the amount of moisture in the sample should be divided by the net weight of the sample. Results should be verified by a PTC representative. A minimum of two tests per day will be required. When conditions exist which would cause a change in moisture content, additional tests are required. After the total shipment has been delivered, an average of all the moisture content tests will be determined and an adjustment of the delivery tonnage will be deducted from the aggregate tonnage shipped. Payment will be based on the calculated oven dry weight. Samples will be extracted from the PTC segregated stockpile for each material release. PTC Inspectors will extract samples and either run appropriate gradation tests or submit samples to PennDOT for gradation testing. NOTE: Commission personnel may conduct pre-delivery sampling and gradation testing, but payments will be based on segregated delivery stockpile sampling and gradation testing.
H. MATERIAL ACCEPTANCE/REJECTION: Acceptance of material will be determined within fifteen (15) days of delivery. Rejection of materials will be determined within fifteen (15) days. Vendor will be notified. Material rejected will remain on a segregated stockpile awaiting removal by vendor for up to ninety (90) days. Failure on the part of the vendor to remove rejected materials after 90 days will result in removal via discretion of the Commission. MATERIAL WILL NOT BE USED AS ANTI-SKID. I. INVOICING: When billing the contractor will furnish an original and two copies of the invoice. In cases where computerization requires the vendor to retain the original copy of the invoice, three copies of the billing will be acceptable, however, one of the copies must be stamped or designated the "ORIGINAL DUE TO COMPUTERIZED OR AUTOMATIC ACCOUNTING." J. QUALIFICATION: Anti-Skid Material must be furnished by vendors on an approved PennDOT list as appearing in PennDOT Bulletin #14. Selected vendors must also provide their firm's license number as required by the Commonwealth of Pennsylvania - Surface Mining Conservation and Reclamation Act dated May 31, 1945 as amended, or provide documentation why such license is not required.
