GENERAL
The following procedures should be used for the receipt of and documentation for payment of materials when weight tickets are the basis of payment. Reference should also be made to
Article 106-7 of the Specifications and this Manual.
TICKETS ISSUED FOR PAYMENT BY WEIGHT
When material is to be paid for on a weight basis, the Contractor is required to furnish platform scales or other weighing devices certified by the North Carolina Department of Agriculture. The scales must be operated by a North Carolina public weighmaster, and a certified weight certificate must be issued in the form of a ticket. This ticket can be physical or electronic.
All platform scales should be of sufficient length to permit weighing of the hauling equipment in such a manner that when weighing trucks with trailers, the entire hauling unit can be weighed as a unit. If the platform scale is not of sufficient length, the truck and trailer should be detached and weighed separately.
Upon delivery of materials paid for by weight, the Contractor should immediately give the weight ticket to the construction technician performing the inspection.
Upon receipt, the construction technician should make sure the ticket is legible and the following information has been listed on the ticket:
- The Department Contract Number/WBS Number.
- The date the ticket is issued.
- The time the ticket is issued if the material is asphalt plant mix or plant mixed cement treated base course.
- The type of material represented by the weight ticket.
- The gross weight of the vehicle. (platform scales)
- The tare weight of the vehicle. (platform scales)
- The net weight of the material.
- The location of the quarry or plant where the material came from.
- The number of the truck transporting the material.
- The name of the prime Contractor for the project.
- The stamp or number of the public weighmaster weighing the material.
- The appropriate Job Mix Formula (JMF) number for the asphalt plant mix.
When trucks with the same identification number are being used by the Contractor, care should be taken to ensure that sufficient additional information is noted such that the trucks can be distinguished from one another.
Upon determining that all required information has been furnished on the weight certificate, the Inspector should then list the following information on the ticket:
- Contract Number/WBS Element Number if not shown on the ticket.
- WBS Element Number if different from that shown on the ticket.
- Contract item number by which material will be paid.
- Location where the material was placed.
- Date the material was placed if it is different from the date the ticket was issued, such as erosion control stone stockpiled on a previous date anticipating inclement weather.
- Construction Technician’s signature on the first ticket for the day and initials on subsequent tickets.
- Quantity reduction for unused portion of material and reason should be shown clearly on the ticket.
- The time the ticket is received for asphalt plant mix or plant mixed cement treated base course.
Tickets for each day should be bound separately with the total for the day shown on the front cover.
