2003 SPECIFICATIONS

SECTION 106

106.07 Use of Materials. Material identified by seal numbers and heat numbers, such as cement, asphalt, structural steel, metal pipe, etc., must have the identifying number checked against the appropriate test reports, invoice, etc. Some materials require significantly more detailed testing than others. The specific requirements for all materials are given in the sections of this manual pertaining to the material involved and in the "Manual of Field Sampling and Testing Procedures".

106.08 Use of Telephone to Confirm Approved Test Reports. The use of the telephone for receiving approved test results is authorized and is to be used to expedite the work. It is necessary to have knowledge of approved test results on all materials prior to their incorporation into the work, but oral approval via telephone is acceptable until written reports are received.

The receiving of approval by telephone does not mean that a written report is not necessary in the files. The Resident Engineer should notify the Materials Division if this written report is not received in a reasonable length of time.

Proper documentation in the Diary and other records of all telephone conversations is essential to the job files and this includes all test results received by this

medium.
