1.2.1 Quality Control – Planned and specific actions or operations necessary to produce a product that complies with the Contract Documents. Quality Control consists of actions, inspections, sampling and testing necessary to ensure the Work is in compliance with the Contract Documents and to control production and construction processes. Quality Control is keyed to the construction sequence to quickly determine when the Work is out of compliance with the Contract Documents and to respond to correct the situation and bring the Work into compliance. Quality Control is the responsibility of the Contractor and is at their expense.

1.2.2 Quality Assurance – Construction observation, testing and any other actions deemed necessary to verify that the Work complies with the Contract Documents as determined by the Owner. Quality assurance includes observation of the Contractor’s Quality Control, verifying the results of the Contractor’s testing and additional Quality Assurance sampling and testing. Quality Assurance will not be adequate for the Contractor’s production and placement needs. The Owner and/or Contracting Officer will provide Quality Assurance as deemed necessary. The expense of Quality Assurance is the responsibility of the Owner.

1.2.3 Verification/Compliance Testing – Sampling and testing which is carried out independent of the Contractor’s Quality Control testing to confirm/verify that the Work complies with the Contract Documents. The frequency of verification/compliance testing will be determined by the Owner and may not be adequate for the Contractor’s production and placement needs. Verification/compliance testing will not be used to determine construction procedures or operations (i.e. rolling patterns, lift thickness, etc.). Verification/compliance testing will be provided by the Owner and/or Contracting Officer. The expense of Verification/Compliance Testing is the responsibility of the Owner.

1.3 SUBMITTALS:

1.3.1 Prior to mobilizing, submit a Quality Control Plan defining the program and the documentation proposed to ensure that all materials and work conform to the Contract Documents. The plan shall identify personnel, procedures, control, tests, frequency of tests, and records and forms to be used. Quality control testing frequency is at the Contractor’s discretion.

1.3.2 Submit records of all tests to the Contracting Officer within 24 hours of the testing. The Quality Control laboratory shall notify the Contractor and Contracting Officer promptly of irregularities or deficiencies observed in the Work during performance of the Quality Control Testing.

PART 2 – PRODUCT

NOT APPLICABLE

PART 3 – EXECUTION

3.1 General – Be responsible for quality control tests and inspections to control Contractor production and construction processes. Include in the Contractor quality control system an internal organization, plans, and procedures to produce the specified end product. Assure the system covers all construction operations, both on-site and off-site, and is keyed to the construction sequence.

3.2

Contractor Cooperation with Quality Assurance Agency – Assure the Contracting Officer and Owner’s representatives has access to all work areas at all times work is in progress. Provide any special facilities or equipment to access work areas at Contractor expense. Notify the Contracting Officer when the work is ready for Quality Assurance testing. Establish and update the construction schedule to provide the Contracting Officer estimated sampling/testing dates and times.

3.3

Payment for Testing and Re-Testing – Contractor shall pay for all Quality Control testing identified above. Mix Designs for Portland Cement Concrete and Flowable Fill, mix designs for Asphalt Concrete, and all initial aggregate quality tests are quality control tests and are at Contractor’s expense. Testing costs are incidental to the work and are to be included in the lump sum or unit cost bid.
