# S3 Wolfe Park - Concept A: design QA report

Portfolio sample by a fictitious firm (Bow Ridge Geomatics & Landscape). Not for construction.

Checks re-measured from the final geometry and proposed surface: **36** - EXCEPTION 2, OPEN 1, PASS 29, REVIEW 2, RFI 2

Status: PASS meets the criterion; PASS (TREATED) meets it through a noted design measure; EXCEPTION documented deviation; RFI needs an answer from the City; REVIEW minor, fix in detailing; OPEN must be resolved before issue for construction.
