Compare utility material notes, pipe profiles, and the sheet index before procuring buried infrastructure.
The documented result is a set of review findings. This case study does not establish that corrections were completed or that savings were realized. The examples below were marked useful in the source review record; they have been paraphrased to remove identifying details.
Key findings
Sheet index and utility pages disagree
General & Coordination
The index audit flagged one missing page and six mismatches in a 31-page indexed set. Several pages labeled as planting or irrigation corresponded to utility plans.
Next step: Reconcile sheet names and confirm that the intended review set is complete.
Water-main material designation conflicts
Civil
A 10-inch water-main note specifies SDR-35 pipe while the accompanying utility standard calls for AWWA C900 PVC.
Next step: Confirm the pressure-pipe requirement and revise the plan or standard reference.
Storm pipe class differs between plan and profile
Civil
The same 140-foot storm-drain run is called Class III reinforced concrete pipe on one drawing and Class V on another.
Next step: Confirm the required pipe class for the loading and installation conditions.

Anonymized, paraphrased excerpts from a completed project review. These three examples were marked “good catch” in the source review record; that label is feedback, not independent validation. The project total excludes duplicate-group members, dismissed findings, wrong finds, and insufficient-reference findings. Only selected excerpts are published. Customer identity, project address, source identifiers, and private drawings are omitted. Corrections, permit outcomes, and financial savings have not been independently verified. A qualified professional should assess each finding against the complete project documents.
