All quantities in the Price Schedule of the Bid Form or other Contract Documents, which are to be paid per field measurement, are approximate only, and are to be used only as:

1. A basis for estimating the probable cost of the Work, and

2. For the purpose of comparing Bids submitted for the Work.

Actual work performed, and materials furnished under the unit-price items for those items to be field measured may differ from the estimated quantities.

Basis of payment for work and materials will be the actual amount of work done and materials furnished to the pay lines defined in this section.

Payment will be paid at the unit price bid for listed items successfully completed according to Contract requirement.

Lump-sum items and those based on neat-line plan dimensions are not field-measured. They will be paid at neat-line or the lump-sum price bid for the items listed.

PART 1 - GENERAL

SECTION INCLUDES

This section covers the requirements for Quality Control (QC) on all work performed to ensure it conforms to the drawings and specifications.

QUALITY SUBMITTALS

Quality Procedures Plan.

1. A plan that identifies the CONTRACTOR’s representative responsible for the quality of the completed construction and outlines the quality control program (including construction management controls, quality control testing, test frequency, and test agencies).

Quality Control Test Results

A. Submit records of all CONTRACTOR tests to the GOVERNMENT within 24 hours of the completion of testing. The Quality Control laboratory is to notify the CONTRACTOR and the GOVERNMENT promptly of irregularities or deficiencies observed in the Work during performance of the Quality Control Testing.

DEFINITIONS

Quality Assurance (QA): Inspection and tests performed by the GOVERNMENT to assure compliance with the terms of the contract. QA testing is not used to determine construction procedures or operations (i.e. rolling patterns, lift thickness, etc.). Quality assurance also includes oversight of the CONTRACTOR’s quality control, verifying the results of the CONTRACTOR’s testing and additional assurance sampling and testing. QA testing and oversight will be provided by the GOVERNMENT at a level/frequency determined necessary by the GOVERNMENT.

Quality Control (QC): Activities performed by the CONTRACTOR to ensure work conforms to contract requirements.

Quality Control Testing: Tests to be performed by the Contractor.

1. The GOVERNMENT may use the contractor’s QC test results for Quality Assurance.

2. The Contractor may include the GOVERNMENT’s QA test records in the QC test report documenting compliance with the construction documents.

3. The tests required by the individual specification sections do not relieve the CONTRACTOR of providing adequate quality control measures to ensure the completed construction complies with the contract documents.

EXECUTION

COOPERATION WITH QUALITY ASSURANCE:

Assure the GOVERNMENT 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 GOVERNMENT when the work is ready for quality assurance/quality control testing.

Establish and update the construction schedule to provide the GOVERNMENT with estimated sampling/testing dates and times. The GOVERNMENT may choose to obtain a split and comparison test of any samples collected for quality control testing. Provide adequate notice of testing plans to coordinate collection of samples

SAFETY PROVISIONS:

Safety provisions are the responsibility of CONTRACTOR. CONTRACTOR must meet County, State, and Federal laws, regulations and ordinances to protect the public.

DETOURS:

Where required by the authority having jurisdiction that traffic be maintained over any construction work in a public street, road, or highway, and the traffic cannot be maintained on the alignment of the original roadbed or pavement, construct and maintain a detour around the construction work. Include with each detour all necessary barricades, guard rails, approaches, lights, signals, signs, and other devices and precautions necessary for protection of the Work and safety of the public all in accordance with the current edition of the MUTCD.

BARRICADES AND LIGHTS:

Provide all open trenches and other excavations with suitable barriers, signs, and lights to the extent adequate protection is provided to the public. Provide similar warning signs and lights to indicate obstructions such as material piles and equipment.

Illuminate all barricades and obstructions by means of warning lights from sunset to sunrise. Place materials stored upon or alongside public roads (if any) and conduct the work at all times so as to cause minimum obstruction and inconvenience to the traveling public. Install all barricades, signs, lights and other protective devices, and maintain in conformity with applicable statutory or regulatory requirements and as required by the authority having jurisdiction.

Assure all traffic control devices are clean, legible, reflective for night-time use, and operable.

PART 3 - EXECUTION

WORK METHODS:

Place all traffic control devices as planned before permitting men or equipment on the traveled way.

Inspect the work area at least twice each day during construction and maintain records of traffic control devices used and their location.

Assure traffic control is appropriate to the work. Assure traffic control devices are appropriate and clean before suspending work for the day.

Remove and store all unnecessary traffic control devices away from traffic's view.
