900.1 Material Inspection for Traffic Control

This article establishes procedures for reporting the inspection of traffic control devices typically inspected and accepted by the resident engineer’s staff. This encompasses lighting, signal and signing materials that do not have a corresponding Division 1000 Material Details specification or are not typically tested and inspected by Materials personnel.

Materials personnel inspects and accept materials specified in Division 1000 and some aspects of materials such as poles, posts and arms. See the Contract Sampling and Testing Requirements for the specific materials on particular projects that require a separate sample record. Generally, each material with a distinct SiteManager Material Code should have a separate sample record of inspection and acceptance.

900.1.1 Procedure

The material components for traffic control, including highway lighting, traffic signals and highway signing, that are not normally field inspected by Materials, will be inspected and documented. The construction inspector shall confirm that the material components presented by the contractor for use meet the applicable specifications. Any documentation required by the specifications will be obtained from the contractor or the contractor’s agent prior to use of the material. That documentation will be filed with other project documentation as maintained by the resident engineer’s staff.

900.1.2 Report

Using SiteManager, a sample record for Sec 901, 902and 903 materials will be created by the resident engineer’s staff. Three material codes have been provided to allow the creation of the required sample records to acknowledge the inspection of Traffic Control materials. The codes are 0901LHXX for highway lighting, 0902TSXX for signals and 0903HSXX for highway signing. These respective sample records, when appropriate, are to be created in lieu of the District Engineer’s Certification (DEC).

Generally, each sample record is completed according to the instructions in Automation Guide AS-3510. When the materials used for the particular Traffic Control measure come from several sources, the primary producer/supplier of the material may be selected. On the Tests Tab, the test designated as "Dist. Engr. Cert. Sig., Sign, Light" (SAA901AA) is selected and completed. The "Dist. Engr. Cert. Sig., Sign, Light" test states that “The materials and equipment listed by the contractor, including accessories and appurtenances, as required by the Specification and specifically approved by the construction inspector, were those which were incorporated into the work." Any exceptions should be listed on the Free Form Test. The Dist. Engr. Cert. Sig., Sign, Light test may be eliminated and the Free Form Test substituted if it includes, at a minimum, the statement “The materials and equipment listed by the contractor, including accessories and appurtenances, as required by Section [fill in the appropriate section for each sample record] and specifically approved by the construction inspector, were those which were incorporated into the work" [except as follows1]. [List the exceptions and the exceptions’ reasons.]

A listing of the actual items used, their source and any supporting documentation should be included in the project files.

A cathodic protection material code, 3099SPBRCA (Cathodic Protection for Bridge), is provided to allow acceptance by the procedure described above.

1 Optional, depending on circumstances.
