To this end the Contractor is required to establish, implement and maintain an effective Construction Quality Control (QC) Plan. The QC Plan must cover all construction operations both onsite and offsite, and must be keyed to the proposed construction sequence (definable features of work).

B. The Construction Quality Control Plan must include, as a minimum, all quality processes performed by the contractor, subcontractors, fabricators, suppliers, and purchasing agents. ISO 9001:2015 must be used as a base line for developing the control processes identified in Part 3 (Execution) of this specification.

C. The Contractor is responsible for quality control and must establish and maintain an effective quality control system. The quality control system must be defined by the QC Plan, which defines the Contractor’s quality policy, lines of authority and responsibility, QC personnel qualifications, and the procedures and organization necessary to produce a finished product that complies with the contract requirements.

D. The project manager and superintendents will be held accountable for the quality of work and are subject to removal at the direction of the COR for failure to comply with quality requirements specified in the contract. The Contractor’s project manager and superintendents in this context must mean the individuals with responsibility for the overall supervision of field activities for the project.

E. The Government will schedule performance audits during the construction phase to assess the Contractor’s performance against contract requirements and QC Plan implementation. The COR must use the audit results to evaluate the completed work and progress made against the contract documents and project schedule when reviewing Contractor requests for progress payments.

F. Additional requirements for Design/Build Contracts

1. The design quality control program is specified elsewhere in the contract. The Contractor’s QC Plan must include a Design Quality Control process that will ensure that the design is continually up to date with respect to field changes.

Changes to the construction documents must be reviewed and approved by the Architect/Engineer of record.

2. The construction phase design control process must be implemented and coordinated by the contractor’s field engineering staff or the QC Manager. The design control coordinator must be a registered professional engineer. The Contractor must notify the Government who will be responsible for design control coordination and name an alternate as well.

1.02 Referenced/Related Documents: The publications listed below are incorporated into the specification by reference:

A. The three phases of control must be conducted by the QC Manager for each definable feature of work as follows:

1. Preparatory Phase: This phase must be performed prior to beginning work on each definable feature of work; after all required plans, documents, materials are accepted. A preparatory meeting must be called by the QC Manager to demonstrate that the Contractor has all the necessary materials, equipment and personnel to start a definable feature of work. Agenda items must include:

a. Review of the applicable specifications.

b. Review of the contract drawings.

c. Confirmation that all materials and/or equipment have been tested and submittals have been received and accepted.

d. Review of provisions that have been made to provide required control inspection and testing.

e. Examination of the work area to ensure that all required preliminary work has been completed and is in compliance with the contract.

f. Physical examination of required materials, equipment, and sample work to ensure that they are on hand, conform to accepted shop drawings or submitted data, and are properly stored.

g. Review of the applicable safety requirements to ensure they are met.

h. Discussion of procedures for controlling quality of the work, including repetitive deficiencies.

i. Discussion and scheduling for the initial control phase.

j. The Contractor will provide to the COR the agenda 48 hours in advance of the preparatory control meeting. This meeting must be conducted by the QC Manager and attended by the superintendent and foremen responsible for the definable feature of work and other QC personnel as applicable. The results of the preparatory phase activities must be documented by separate minutes prepared by the QC Manager and attached to the daily QC report. The responsible superintendent and foremen must instruct applicable craftsmen as to the acceptable level of workmanship required by the contract specifications.

2. Initial Phase: This phase must be accomplished at the beginning of field construction of a definable feature of work. This phase must be held at the work site with a demonstration of how the work is to be performed in order to meet the contract requirements. If mock-ups are required for a definable feature of work, they must have been completed far enough in advance of the Initial Phase that all materials must have hardened or dried and must be in such condition as the finished product will achieve at completion. Agenda items must include:

a. Review the work to ensure that it is in full compliance with contract requirements as discussed in the Preparatory Phase meeting. The minutes of the preparatory meeting must be reviewed as necessary.

b. Verify the adequacy of controls to ensure full contract compliance.

Verify required control inspections and testing.

c. Establish the level of workmanship and verify that it meets minimum acceptable workmanship standards. Compare with required samples and mock-ups as appropriate.

d. Resolve all differences.

e. Review safety requirements to include compliance with and possible revision of the safety plan and activity hazard analysis. Review the activity hazard analysis with all workers. Ensure that the safety control barriers and/or signs have been correctly installed.

f. The initial phase should be repeated anytime a new crew begins work on a definable feature of work or any time acceptable quality standards are not being met.

g. The Contractor will provide the agenda to the COR at least 48 hours in advance of beginning the initial phase. Separate minutes for this phase must be prepared by the QC Manager and attached to the daily QC report. The exact location of the initial phase must be indicated for future reference and comparison with follow-up phases.

3. Follow-up Phase:

Daily checks must be performed to ensure that control activities, including control testing, are providing continued compliance with contract requirements until completion of the particular feature of work. The checks must be made a matter of record in the QC documentation. Final follow-up checks must be conducted and all deficiencies corrected prior to starting additional features of work which may be affected by the deficient work. The Contractor must not build upon nor conceal deficient work.

B. Completion Inspection (also known as Schedule of Defects):

1. Punch-List Inspection:

At completion of all work or any increment thereof, the contractor must conduct joint inspections of the work with the government. The contractor must record all deficiencies and work identified as not conforming to the plans and specifications, and a list of the findings, by location, must be submitted to the Government within two days after each joint inspection. The list of these findings must constitute the punch-list. At completion of all punch-list work or any increment thereof, the contractor must conduct a joint re-inspection with the Government to verify completion of the punch-list work. Both the contractor and the Government must confirm mutual agreement of completion by signing the punch-list and indicating that each item on the punch-list is complete. The contractor must submit two hardcopies of the signed punch-list and an electronic copy of the signed list in xxx.pdf format.

2. Final Acceptance Inspection:

No later than six (6) weeks after substantial completion the contractor must conduct the joint, final acceptance inspection with the Government. The contractor must provide a minimum of 14-days advance written notice to the Government and certify the work must be complete prior to commencing the final acceptance inspection.

During the joint, final acceptance inspection the contractor must record all deficiencies and all work identified as not conforming to the plans and specifications. A list of the findings, by location, must be submitted to the Government within two days after the inspection. The list of these findings must constitute the list of final acceptance defects. The contractor must immediately complete all work on the list of final acceptance defects. At completion of all items on the list of final acceptance defects, the contractor must conduct a joint re-inspection with the Government to verify completion. Both the contractor and the Government must confirm mutual agreement of completion by signing the list of final acceptance defects and indicating that each item is complete. The contractor must submit two hardcopies of the signed list of final acceptance defects and an electronic copy of the signed list in xxx.pdf format.

3.04 Daily Reporting

A. The Contractor must provide QC Daily Reports that provide factual evidence that required quality control activities and/or tests have been performed. These records must include the work of subcontractors and suppliers and must be on an acceptable form that includes, as a minimum, the following information:
