1020.3 Sample Record

1020.3 Sample Record

The manufacturer is required to notify MoDOT of impending shipments by contacting Materials in the district responsible for their plant and providing the information required by the Pipe Shipping Report Form for reporting to a district office, GS-17 Form 2. Construction and Materials will be notified by shippers (see Pipe Shipping Report Form for reporting to the Central Office, GS-17 Form 1) that are out-of-state and are not routinely visited by district Materials. This information will allow MoDOT to track the material, obtain samples, and perform Quality Assurance inspection as necessary.

An AASHTOWARE Project (AWP) sample record shall be created for each size of pipe and each size of end section in each shipment. A sample record shall only be created for coupling bands when shipped alone. If coupling bands are shipped with pipe or end sections, they will be reported along with the pipe of corresponding size, in the test result details of the Free Form test.

When coupling bands are shipped alone, a single AWP Sample ID shall be issued for all coupling bands in a shipment, regardless of size. A generic material code for coupling bands corresponding to the type of coating shall be used when creating the AWP sample record.

Each AWP sample record will be created by the district responsible for the manufacturer. Construction and Materials will create sample records for pipe shipped by out-of-state manufacturers.

AWP shall be used when submitting samples to the Laboratory. The inspector is to show the following information for each lot sampled:

(a) Type of coating, galvanized or aluminum.

(b) Complete identification shown on the sheet or coil.

(c) Sampling pattern used.

(d) Results of field sheet thickness measurements (minimum and average) for each lot sampled.

(e) Whether corrugation dimensions comply with specification requirements.

Field inspection reports of fabricated pipe, pipe-arches, and end sections shall be made using AWP and should include the size of corrugation and type of fabrication (riveted, spot welded, helical lock seam, or helical welded seam). Pipe quantity shall be shown in feet. End sections shall be shown as quantity each. The length of barrel of the end sections shall be included in the remarks and shall not be counted toward the materials summary unless the length contributed is necessary to eliminate a significant summary deficiency. The sample record is to indicate acceptance or rejection. If the sample record indicates rejection, the reason for rejection shall be stated in the remarks or the test result details of the sample record. If the sample record indicates acceptance, the basis of acceptance of the metal shall be on results of Laboratory tests or the approved brand and an examination of the material, and because fabrication is satisfactory.

Random spot-checking for weight (mass) of coating or thickness, visual examination of helical lock seams or weld seams, and tension testing of lock seams performed by the manufacturer, is to be recorded in the inspector's diary and need not be recorded on the inspection report.

When lock seam samples are sent into the Central Lab for testing, the AWP “1020CPCSLS Culvert Pipe Lock Seam” material code will be used on the sample record.
