QA/QC and Documentation Approaches at Hinterland Group

At Hinterland Group, rigorous QA/QC (Quality Assurance/Quality Control) protocols and thorough documentation are foundational to every project. This commitment ensures that all pipeline rehabilitation, testing, and inspection phases meet or exceed industry, municipal, and client standards across the southeastern United States.

Overview of QA/QC in Pipeline Rehabilitation

Scope: Applies to all trenchless pipeline rehab methods (CIPP, SIPP, pipe bursting, sliplining), manhole coating, lift station repair, and stormwater/wastewater asset management (Services).
Purpose: Minimize risk, optimize asset performance, maintain regulatory compliance, and ensure project transparency for all stakeholder types (municipal, commercial, industrial, property management, HOA).
Industry Focus: Water, wastewater, stormwater, and critical transportation infrastructure.

Structured QA/QC Process

1. Pre-Construction/Pre-Rehab CCTV Inspection

Purpose: Establishes a verified baseline of pipeline and structure condition for accurate project scoping and planning.
Technology: Uses advanced vactor equipment and robotic CCTV inspection cameras for high-resolution digital imaging, defect coding, and video/document archive (Inspection Services).
Documentation: All initial inspections are logged, with defect types coded according to industry standard (e.g., NASSCO PACP codes if specified).
Deliverables: Clients receive detailed inspection reports with video files and annotated defect lists to inform decision-making. These are typically in digital format and may be provided in formats compatible with municipal asset management systems.

2. Test Data Collection (During and Post-Construction)

Types of Testing: After cleaning and before/after CIPP or other rehab methods, testing may include:
Infiltration/exfiltration water or air pressure testing
Liner wall thickness measurement and cure verification
Leakage testing
Mandrel deflection testing (for flexible pipes)
Standards: All work is documented and tested following applicable ASTM, AWWA, and municipal requirements.
Data Recording: Test data is logged with time, location, test parameters, and results. If failures occur, remedial actions and retests are reported.
Sampling: For CIPP, cured liner samples may be extracted for physical property verification as specified by contract requirements.

3. Post-Rehab CCTV/Verification

Purpose: Directly verifies quality of installed liner, repair, or replacement work.
Technology: Post-installation CCTV inspections follow the same technical protocols as pre-rehab inspection but focus on identifying any remaining or new defects, confirming reinstatement of laterals, and verifying project completion standards.
Documentation:
"Before/After" video and photographic records
Comparison tables or annotated overlays highlighting improvements
Digital reports submitted to client/municipality
Record Retention: All digital records are archived for future asset management or warranty needs.

4. Comprehensive Project Reporting

Content:
Project summary (scope, methods, dates)
Pre- and post-inspection findings (with media)
Test data and QA/QC validation steps
Summary of any deviations, remedial actions or change orders
Maintenance and warranty recommendations (Maintenance Services)
Delivery: All reports are delivered in client-preferred format (digital, cloud, or hard copy), suitable for direct integration into municipal/enterprise documentation systems.
Transparency: Clients are kept informed throughout with interim milestone updates and real-time access to key testing/certification results as they occur.

Standards, Certification, and Quality Personnel

Safety & QA Leadership: Projects are overseen by certified supervisors and a dedicated full-time Safety Manager/OSHA Certified Instructor (About).
QA/QC Certifications:
Inspector and operator positions require licensure and ongoing certification per industry guidelines.
Third-Party Audits:
If contractually required, Hinterland accommodates and cooperates with independent QA/QC auditors for critical milestones or final acceptance.
