B.5 QUALITY CONTROL AND QUALITY ASSURANCE

Note: See Appendix 1 below for a detail QASP

B.6.1 Introduction. A principal factor of performance on this project is the Contractor’s control of the quality of workmanship. The Contractor shall establish and maintain a project-specific

Quality Management Program (QMP) which defines and implements a quality system. The quality system is a documented organizational process which describes responsibilities, procedures, and resources for providing quality control and quality assurance on a project. Effectiveness of the

QMP is achieved through adequate planning, forceful direction, and checking in the sense of measurement and evaluation. The QMP applies to the control of quality throughout all areas of contract performance.

B.5.2 Quality Management Program:

The Contractor’s QMP shall be COR-approved to provide employees, consultants, and/or joint-venture partners with established, uniform procedures for production of project data and documents throughout the construction process. Principal functions of the QMP are the following:

5.2.1 Quality Control (QC):

Operational techniques and activities that are used to fulfill requirements for construction quality.

5.2.2 Quality Assurance (QA): Documentation of planned and systematic actions required to provide confidence that construction services provided are based on project requirements and satisfy stated requirements for quality.

B.5.3 Audits After award of the Contract:

The Government may perform audits of the Contractor’s QMP to periodically assess conformance with the QMP. Disapproval of the program, or major portions, may be cause for a delay in progress of the project’s development or, in some cases, withholding acceptance of the Contractor’s performed services. The Government may examine the Contractor’s existing quality system prior to award of this contract as part of a pre-contract assessment, in order to determine the ability of the Contractor to satisfy the “quality” requirements of this contract.

B.5.4 Agreement on Quality Assurance:

The Contractor shall develop a clear understanding with all his consultants on quality assurance matters for which the contractors are responsible, and the quality assurance program of the contractor shall be integrated with that of the Contractor of record.

B.5.5 Organizational Structure:

The Contractor shall define and submit a QMP organizational structure within 15 days of contract award, including charts and a description of responsibilities of key persons who will perform the services.
