Quality Assurance / Control
GC&T has a comprehensive in-house Quality Assurance and Quality Control(QA/QC) Program.
Our instituted and implemented Quality Assurance Manual is
available to our clients for their review upon request. This
document focuses on quality control measures that apply
during project execution ensuring our work
is technically appropriate, accurate, and complete. A summary of the
in-house Quality Control Program is as follows:
field inspectors are certified by the Washington Area Council of
Engineering Laboratories (WACEL), American Concrete Institute (ACI),
and/or the Virginia Department of Transportation (VDOT) in Soils,
Concrete or Asphalt. The field inspectors work directly under the supervision of registered professional engineers.
The inspectors, who perform soil compaction testing utilizing a Nuclear gauge, must attend an eight (8) hour Nuclear Gauge and Radiation Safety Training seminar.
Each inspector, when employed, spends a minimum of 40 hours in training
offered in-house to become familiar with the company policies and
our field staff is interconnected to a telecommunications network that
keeps them in continuous contact with our project engineers. At
least one engineer is present in the office at all times when
inspectors are working in the field to provide assistance and to answer
questions if required.
engineering and testing services are supported by an accredited
in-house materials laboratory that enables us to efficiently perform
the tests necessary to analyze the different construction materials and
establish their engineering properties. Our laboratory facility
is inspected by the AASHTO Materials Reference Laboratory (AMRL) and
the Cement and Concrete Reference Laboratory (CCRL) of The National
Institute of Standards and Technology and WACEL at regular intervals to
review our testing and inspections procedures.
