Legacy Cross Bores - Project Operations Flow Chart

Project Management and Planning

• New Techniques and tools offer the ability to locate and subsequently eliminate previously constructed cross bores before collateral damage and injuries occur.
• Essential to utilization of the new technologies and techniques is a plan for utilization.
• The plan should be considered to have a strong QA/QC component for verification of the extent and thoroughness of the field work.
• Physical re-inspection by different field crews of a percentage of prior completed inspection work is recommended as part of the QA/QC program.

Flow Chart and PowerPoint Presentation

• A Flow Chart and Presentation (courtesy Hydromax USA) and has been developed for Legacy inspection for cross bores
• QA/QC processes are essential for a high confidence level
• Multiple tools and techniques should be expected to complete a project. If one tool/technique is not successful, then alternate methods must be selected until 100% of potentials are inspected.
• The process depicted is field and office QA/QC to be effective
• Alternate new technologies should continually be evaluated as they become available.
