This presentation highlights why detailed data collection is important during condition assessment and the need for continued coordination between the design engineer and condition assessment engineer during the design process. The Yard Piping Program is now finishing Phase 2 and Phase 3 is underway. Lessons learned during Phase 1 and Phase 2 construction have identified best practices for documenting observations and will be carried forward to Phase 3. For Phase 2 specifically, rehabilitation construction was 5 years after the condition assessment and the pipeline condition changed. The presentation will start with an overview of the assessment approach and findings for a specific pipeline. Next the design package preparation will be discussed, including assumed allowances for construction. This will be followed by construction progress and engineering services provided during construction. The presentation will end with lessons learned.
