Additional testing requirements are as specified in the most recent update of Section 900 of the Arizona Department of Transportation, Materials Testing Manual. The contractor may provide certificates of analysis or certificates of compliance for items identified in the City of Tucson/Pima County Standard Specifications for Public Improvement in lieu of the testing requirements of those materials identified in the ADOT Materials Testing Manual.

(B) Specific Contractor Quality Control Measures.

Quality Control Plan: At the preconstruction conference, the contractor shall designate a qualified employee as Quality Control Manager to be responsible for implementing, monitoring and, as necessary, adjusting the processes to ensure acceptable quality. Also at the preconstruction conference, the contractor shall be prepared to discuss his understanding of the quality control responsibilities for the specified materials.

Records: The contractor shall maintain complete testing records and make them available to the Engineer for review and copies as requested.

Weekly Quality Control Reports: The contractor shall submit Weekly Quality Control Reports to the Engineer. The weekly reports shall state the types of work, such as earthwork, Portland cement concrete, or asphaltic concrete, which have been performed during the report period, and shall also include the process control measures taken to ensure quality. The weekly report shall provide sample identification information for materials tested during the report period, including sample number, date sampled, sample location, person obtaining sample, and original source of material. The report shall also provide the results for all required tests and any retests, corrective actions, and any other information relevant to quality control. Although hand-written documentation can be included, the quality control report narrative, sample identification information, results for tests and any retests, and corrective actions shall be typed to ensure the Department can make clear reproductions of the documents.

The report period shall end at midnight of each Friday, and the report shall be submitted to the Engineer no later than 5:00 p.m. of the following Wednesday or at a time agreed upon by the Engineer.

CenturyLink/Lumen

Protect in place and maintain a minimum of 12 inches of vertical and horizontal separation from existing underground and aerial CenturyLink/Lumen facilities at all times.

Additionally, CenturyLink/Lumen request to be notified of upcoming coordination milestones or

Preconstruction Meetings, to review updated plans before advertising, and to ensure state-law requirements are followed for blue staking, facility protection, and minimum separation during construction. ROW acquisition is the municipality’s responsibility and that any necessary facility relocations may be at the sponsoring agency’s expense, with contractors required to contact

CenturyLink/Lumen if unknown facilities are encountered.

Cogent Communications

Protect in place and maintain a minimum of 12 inches of vertical and horizontal separation from existing underground Cogent Communication facilities at all times.

Cox Communications

Protect in place and maintain a minimum of 12 inches of vertical and horizontal separation from existing underground and aerial Cox Communications facilities at all times.

The contractor is responsible for complying with all utility-locate laws and verifying the location of all nearby utilities, including Cox Communication Facilities, and must ensure they remain supported and protected throughout construction activities. If work occurs near Cox

Communication Facilities, the contractor is required to perform potholing and take all necessary measures to prevent disturbance or damage.
