PART 1 - GENERAL

DESCRIPTION:

This section includes the procedures for submittals. Items that need to be reviewed by the GOVERNMENT are included.

PRODUCTS

Not Used.

EXECUTION

SUBMITTAL PROCEDURE:

Coordinate all submittals and review them for accuracy, completeness, and compliance with contract requirements; and indicate CONTRACTOR's approval thereon as evidence of such coordination and review. Items submitted without evidence of the CONTRACTOR's approval will be returned for resubmission.

Date and Number: Forward to the GOVERNMENT at least 30 days prior to needing approval or delivery to the site all items required by the individual sections of the specifications.

Cover Letter: Forward all submittals with a cover letter from the CONTRACTOR, identifying the Project and the portion of the Project to which it applies. Submittals that are related to or affect each other shall be forwarded simultaneously as a package to facilitate a coordinated review.

Uncoordinated submittals will be rejected. The GOVERNMENT reserves the right to require submittals in addition to those called for in individual sections.

Electronic Submittals: An internet-based electronic submittal and review system will be available for this Project. The use of this system will be organized by the GOVERNMENT at no cost to the CONTRACTOR and will be the means for receiving and reviewing submittals.

GOVERNMENT'S APPROVAL:

The GOVERNMENT will indicate approval or disapproval of each submittal and, if not approved, will indicate reasons therefor. Any work done prior to approval shall be at the CONTRACTOR's own risk. Any work done, or materials provided, prior to approval will not be eligible for payment until approval is obtained. Approvals do not relieve the CONTRACTOR from responsibility for complying with the requirements of this Contract. If submittals show variations from the Contract requirements, the CONTRACTOR shall describe such variations in writing in the cover letter at the time of submission. The request for a variation shall include a proposal addressing the net effect on the contract price and time.

BLM QUALITY CONTROL/QUALITY ASSURANCE

Print Date: January 2025 01400-1 \\dowl.com\j\Projects\62\22014-01\81Specs\01400_QC_QA.docx

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.

DEFINITIONS:

Quality Assurance (QA) – Inspection and tests performed by the Government to verify the Work complies with the contract documents. QA testing is not used to determine construction procedures or operations (i.e. rolling patterns, lift thickness, etc.). QA 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 at a level/frequency determined necessary by the GOVERNMENT.

Quality Control (QC) - Activities performed by the Contractor to ensure work conforms to the contract requirements. 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. QC is the responsibility of the CONTRACTOR.

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

1. The Government may use the contractor’s QC test results for QA.

2. The Contractor may include Government 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 QC measures to ensure the completed construction complies with the contract documents.

SUBMITTALS:

Quality Control 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).

2. The plan will also describe the Contractor’s quality control testing program, including identification of qualifications of the company and personnel performing the field sampling and testing, qualifications of the laboratory that will perform the laboratory testing, and field procedures that will be followed to ensure testing is being performed within the specified testing frequencies.

Quality Control Test Results

1. 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 GOVERNMENT promptly of irregularities or deficiencies

PART 3 - EXECUTION

QUALITY CONTROL

The Contractor is responsible for adequate quality control and to develop and submit a quality control plan describing how the WORK will be performed in compliance with these specifications.

The Contractor must conduct tests and inspections to document that his process control is achieving the specification requirements.

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. 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 the collection of samples.
