Manual review is constrained by time and sequential sheet checking. The issues that survive require holding multiple sheets and disciplines in view at once, exactly where AI-assisted full-set review changes coverage.
Equipment may fit on plans but lack service clearance when structural, architectural, and mechanical sheets are combined: roof units without compliant access paths, VAV boxes without panels, MRIs squeezed by shafts.
conflicting structural curing requirements vs mechanical rough-in order, sleeve placement vs post-tension stressing rules, fault lines across three drawing series.
Individual tolerances can be acceptable yet fail in combination at interfaces (steel, CMU, precast, envelope gaps). Evaluate against cited industry tolerancing references when reconciling worst-case fits.
Duct vs beam flange clearance, civil perimeter grade vs ADA entrance shown only on architectural narratives, classic multi-discipline failures. Tie to MEP coordination checks and drawing coordination process.
Simultaneous cross-reference across structural, MEP, civil, and architectural PDFs surfaces the categories above faster than sheet-by-sheet human passes on 300+ sheet CDs, supporting GC preconstruction with prioritized logs before GMP.
MEP/structural clashes, access, sequencing, tolerances.
As early as feasible; pre-GMP minimum on many commercial jobs.
Buildability/coordination vs code/engineering noncompliance.
Design team for discipline gaps; GC precon for sequence/tolerance flags.
