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.

Page 4: Quality Assurance & Quality Control

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.

Page 5: Quality Assurance & Quality Control

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.

Page 8: Quality Assurance & Quality Control

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).

Page 9: Quality Assurance & Quality Control

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.

QA Responsibilities

Page 10: Quality Assurance & Quality Control

QA Responsibilities

o Evaluate the contractor's project schedule.

o Review and make recommendations to LSS regarding any delays to the

project schedule.

o Review and evaluate change orders proposed by the contractor, owner,

designer, or QA team. All change orders will require a signature indicating

approval from all above-referenced parties as well as the Department of

Environmental Quality.

o Provide other technical support to LSS as required.

Page 12: Quality Assurance & Quality Control

QA Responsibilities

Geotechnical QA Manager - The Geotechnical QA Manager will be on

site during all earthwork operations requiring quality assurance testing,

including excavation and site preparation, and construction of the

Groundwater barrier wall (GWBW) and cap. They will oversee the

activities of the Field QA Inspectors and coordinate the testing programs

of the QA Laboratory.

QA Laboratory - The QA Laboratory will be an entity independent of both

LSS and the construction contractor, located either on site or off site. It

will be responsible for conducting tests on soil materials and soil-reagent

mixes to ensure conformance with the contract plans and specifications.

The QA Laboratory will not analyze soils or soil-reagent mixes provided

by any party involved with the supply of materials, the construction

contractor, or subcontractors. The QA Laboratory will report directly to

the QA Manager.

Page 13: Quality Assurance & Quality Control

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

equipment and materials.

Page 14: Quality Assurance & Quality Control

Construction Quality Control

Team/Authorities

Key positions in the construction contractor’s QC team will be delineated

in the construction contract; e.g., Contractor Superintendent, Contractor

QC Manager, etc. Other QC authorities and responsibilities will be

assigned at the discretion of the procured contractor. The construction

contractor's QC team will be subject to the review and approval of the QA

Manager before site mobilization is authorized. Team members may be

employed directly by the contractor, or as subcontracted firms or
