contractors enhance their opportunity for additional NATO and
US Government business by maintaining a strong Quality Control
(QC) system. Scheduled goals are achieved through regular production/QC
meetings and proactive contractor leadership that "builds
it right the first time" and builds it safely. QC staff
manage specified QC processes, including submittals, preventative
controls, inspections, tests and documentation. The contractor
manages daily quality control of all trades from project award
through to completion inspections and acceptance by the customer.
The inspector, in its quality assurance (QA) role, assures that
the contractor's QC system is effective.
phase control concept.
The contractor's control of quality is divided into three
phases for each Definable feature of work (DFOW). A DFOW is
a task that is separate from other tasks and has control requirements
unique to that task. Typical examples of DFOW's are exterior
water piping, excavations for foundations , masonry walls,
interior electrical wiring, etc. Performance of all three
phases is the contractor's responsibility. Each control phases
is an opportunity to prevent problems and costly rework.
Is performed and documented prior to starting the DFOW: Example
actions include: reviewing and approving submittals, reviewing
applicable contract drawings, specifications, test requirements,
safety requirements and activity hard analysis, inspecting
delivered materials and construction to be interfaced with
etc. Construction standards and contract interpretation issues
are discussed and settled before start of the DFOW to avoid
the need for "tear out" after work is in place.
The preparatory process pays dividends by locating and resolving
conflicts in advance of construction.
Produce a quality product on time, safely and in compliance
with the contract.
Provide a quality control system that prevents deficiencies.
Identify each proposed DFOW and establish a 3-phase control
Inspect construction and perform specified testing to ensure
Track and correct any non-complying work.
Provide submittals of all products incorporated into the work.
Document and maintain records of all QC activities.
Perform punch-out inspections and participate in Pre-final
and final acceptance inspections.
Requirements for developing the QC plan are found in the QC
specifications of the contract. The contractor submits a QC
plan showing how the designated QC organization will proactively
manage and control all on-site operations, and off-site fabrication,
e.g. structural steel, pre-cast concrete, major systems.
Prior to the start of work, a pre-construction conference,
a QC plan meeting and a coordination and mutual understanding
meeting are held. These meetings assure a complete understanding
of the QC system and clarify the interrelationships between
contractor and customer personnel. During construction, the
contractor conducts regular QC/progress meetings, preparatory
and initial phase meetings.
Is performed and documented at the beginning of each DFOW.
This is an opportunity for the contractor to get the work
off to a proper start in compliance with contract requirements
and to establish standards and quality of workmanship. Testing
procedures and compliance with safety standards are validated.
The initial phase helps to achieve preventative control and
to reach early agreements on quality.
and Procedure Control
The contractor is responsible for review, approval and management
of submittals and for timely delivery of approved materials,
fabricated items and equipment to be installed. The contract
lists the required submittals. The QCM certifies that each
submittal is in compliance with the technical provisions of
the contract. The
contractor prepares a submittals register and a network of
scheduled activities, updated each month to minimize the potential
for construction delays due to missing or unapproved materials
or equipment. The schedule must allow adequate time for customer-approved
Testing is the contractor's responsibility and is essential
to controlling quality. The contractor must:
Check the contract to determine required on-site and off-site
Select qualified personnel, labs, equipment and procedures
that comply with specified standards.
Schedule timely testing and follow up testing.
Submit required testing documentation in a timely manner.
The QAR may check laboratories, equipment and procedures for
For each DFOW is surveillance, inspection and documentation
of the work to determine continuation of compliance with the
contract requirements and quality of workmanship confirmed
during the preparatory and initial phases. The follow-up phase
may be performed on a daily, routine or predetermined basis
as required to ensure contract compliance. The follow-up phase
is more productive when preceded by thorough preparatory and
Completion inspections by the contractor's QC organization
ensure a facility that complies with the contract for turnover
to the customer. When work is complete, the QCM conducts a
punch out inspection. After correction of the punch list work,
the QCM participates in a pre-final inspection and final acceptance
inspection with the customer. Effective QC action enables
the contractor to expeditiously schedule and complete outstanding
compliance items. Prompt completion allows full payment to
Documentation is the proof of QC efforts and contract compliance.

and safety compliance. Daily QC reports list the DFOW, phase
of control, observations, results of control actions taken
and any corrective actions. Include complete information on
the 3 phase controls, inspections, tests, rejected work and
safety monitoring. Document instructions received from the
customer. Each daily report must be referenced to its associated
Schedule Activity ID.
Assurance Representative Role
The quality assurance representative, QAR will review daily
reports and other required documentation to determine the
adequacy of the contractors QC system. The QAR' interest is
that the contractor maintains the necessary control to prevent
any "rework" or tear out. The QAR will emphasize
inadequacies in the quality control program instead of individual
Construction quality management (CQM) requires the combined
efforts of contractor QC personnel and customer QA personnel
to achieve our shared goals - quality construction built safely,
on time and within budget.
