What is Quality Assurance?
Quality Assurance (QA) is a way of preventing mistakes or defects
in manufactured products and avoiding problems when delivering
solutions or services to customers.
ISO 9000 defines quality assurance as "A part of quality management
focused on providing confidence that quality requirements will be
fulfilled“
Quality Assurance (QA) refers to the process used to create the
deliverables, and can be performed by a manager, client, or even a
third-party reviewer. Examples of quality assurance include process
checklists, project audits and methodology and standards
development.
What is Quality Control?
Quality control (QC) is a process by which entities review the
quality of all factors involved in production.
ISO 9000 defines quality control as "A part of quality management
focused on fulfilling quality requirements".
Quality Control (QC) refers to quality related activities associated
with the creation of project deliverables. Quality control is used to
verify that deliverables are of acceptable quality and that they are
complete and correct. Examples of quality control activities include
inspection, deliverable peer reviews and the testing process.
Responsibilities in Quality Assurance
& Quality Control
The construction contractor will be responsible for the quality of
construction in the finished product and for compliance with the
construction documents, drawings, and specifications.
The Project Engineer will have ultimate responsibility for the oversight of
construction and for conformance with the construction drawings,
specifications, and quality assurance requirements.
The QC team members will be employed by the construction contractor.
Therefore, specific positions, and their associated descriptions and
responsibilities, will be set forth by the contractor procured.
However, the construction contract documents require that the contractor
assign an individual to manage the QC team and that the individual will not
be directly involved in supervising construction activities.

Construction Quality Assurance
Team/Authorities
The QA team will solely participate in the quality assurance function and
will not be involved in any other aspect of the construction effort. This
team will, however, possess all of the credentials, capabilities, and
experience of an independent design/construction oversight team. The
duties and responsibilities of each position are described below. One
individual or entity may perform multiple QA responsibilities.
QA Responsibilities
Project Engineer - The Project Engineer is responsible for overall
implementation and management of the QA/QC Plan and will supervise the
preparation of the construction certification report. The Project Engineer
will be independent of the construction contractor, but directly accountable
to LSS for the successful completion of the work. The duties and
responsibilities of the Project Engineer include the following:
o Review and approve construction drawings.
o Provide support to the QA Manager in interpreting the meaning and intent
of the construction plans and specifications and in the performance and
supervision of the QA testing program.
o Provide consultation and technical support to Legacy Site Services (LSS).
o Identify, as appropriate and in coordination with the QA Manager,discrepancies or deficiencies in project work. Any deficiencies deemed bythe Project Engineer to require immediate attention will be reported to LSSimmediately.
o Sign, certify, and seal the construction certification report as a ProfessionalEngineer registered in the state of Oregon, who attests to the quality of thework being certified. The report will include the results of all QA and QCtesting and deviations from the construction plans and specifications. Inaddition, the report will include "as-built" drawings, daily inspectionreports, photographs, and other applicable documents.
o Prepare the final "as-built" drawings indicating the features constructedand the existing location of all features.
o Make recommendations to LSS regarding the approval of constructionsubcontractors and material vendors.

by any party involved with the supply of materials, the construction
contractor, or subcontractors. The QA Laboratory will report directly to
the QA Manager.
QA Responsibilities
Field QA Inspectors - Field QA Inspectors will report directly to the QA
Manager and will be present during all major construction activities. The
duties and responsibilities of this position include the following:
o Visually inspect materials imported to the site for conformance with
contract specifications and for variations from tests completed prior to the
materials being delivered to the site.
o Obtain samples for geotechnical QA testing.
o Observe field sampling and testing performed by the contractor's QC staff,
and review test results.
o Observe and record observations regarding the storage and handling of
