Constructability Issues: Problems AI Catches That Manual Reviews Miss
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.

Access and maintenance conflicts
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.
Construction sequence dependencies
conflicting structural curing requirements vs mechanical rough-in order, sleeve placement vs post-tension stressing rules—fault lines across three drawing series.
Tolerance stack-ups
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.
Cross-discipline coordination gaps
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.
How AI changes coverage
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.
Frequently asked questions
Most common issues?
MEP/structural clashes, access, sequencing, tolerances.
When to find them?
As early as feasible; pre-GMP minimum on many commercial jobs.
Constructability vs design error?
Buildability/coordination vs code/engineering noncompliance.
Who resolves?
Design team for discipline gaps; GC precon for sequence/tolerance flags.
