Construction Quality Control and Quality Assurance Programs

Quality control is a critical responsibility for all Terracon employees. Management and technical functions operate under Terracon’s Quality Control/Quality Assurance (QA/QC) policy and procedures manual. The quality program assigns the immediate responsibility of construction quality control to the project manager with oversight from senior management. The following elements of quality control are addressed during the project:

  • Operational procedures
  • Qualifications of personnel
  • Condition and accuracy of instruments and equipment
  • Standard materials
  • Statistical evaluations
  • Supervisory review of technical procedures and documents
  • Use of control standards for evaluation of activities
  • Sample identification, protection, chain-of-custody, storage and disposition
  • Data recording, identification, security, checking, routing, filing and disposition

We have developed standard operating procedures for various tasks so consistent project quality can be obtained. The procedures are considered guidelines for office managers, project managers, project engineers and scientists to provide direction to Terracon field personnel. The procedures are flexible enough to account for the variations that exist between offices in such arenas as state regulations, site conditions and geology.

Our operating procedures provide direction to staff and require accurate documentation of field services. Field data is assembled and checked by project engineering personnel prior to recommendation development. Site characterization work and design tasks are reviewed by senior management personnel for technical accuracy and conformance to client objectives. In addition to the field procedural guidelines, Terracon utilizes a two-step review process to produce reports and designs. The work product is reviewed by a senior authorized reviewer in draft form prior to the submission of a final report to the client. All authorized reviewers have completed rigorous training and must meet certain guidelines as far as education and years of experience.
