Key Components of a QA Program
While QA programs are unique from project to project, there
are a number of essential elements common to all successful
QA efforts. Some of the key elements are typically presented
in the general provisions of contract documents, while othersespecially
those specific to masonry mortarmust be defined explicitly.
As part of any QA program, quality policies set forth minimum
standards for all materials in the project. Administrative
responsibilities and procedures are established to ensure
a smooth flow of information, and records retention procedures
keep stored information consistent and easy to manage and
locate. Procedures are established for identifying and implementing
corrective action as part of quality control.
Getting Specific: QA and Masonry Mortars
In a QA program that monitors use of masonry mortars, procedures
for review and approval of submittals must be established.
Submittals (and their subsequent approval) ensure that the
specifiers requirements are met regarding construction
materials and procedures.
Mortar submittals should confirm that mortar contains the
specified materials, is of the proper mortar type, and conforms
to project-specific requirements like color, climate considerations,
etc. Each project will require a different level of documentation,
testing and sampling. In general, letters from the manufacturer
certifying materials, and from the contractor pledging to
proportion the materials as specified, are sufficient.
Also key to masonry-specific QA is the establishment of quality
control requirements for masonry mortars, as well as responsibility
for evaluation of test and inspection reports. (More information
on testing is included later in this unit.)
Quality Control as Part of a Quality
Assurance Program
While QA is the overall process that helps ensure a successful
project, quality control (QC) is a valuable component of that
process, one that compares the quality of work with established
standards and dictates appropriate action. There are four
key components of QC: inspection, testing, evaluation and
corrective action.
A closed loop approach forms the basis for effective
QC. In a closed loop approach, accountability and reporting
ensure that every time a project component is inspected or
tested, the results are evaluated and, if necessary, corrective
action is taken. Plans are modified and the resulting changes
in the construction process are carried out, once again evaluating
the results to determine if further action is necessary. The
same is true for the construction process itself: the QC continues,
with communication about each inspected or tested component
traveling in a loop until the evaluated results are acceptable.
