Specification books can be 2,000+ pages. Drawings can be 500+ sheets. When the spec says one thing and the drawing says another, contractors are forced to issue RFIs, and sometimes install the wrong thing. AI plan review catches these conflicts before construction.
Drawing details show hollow metal storefront, but specification calls for aluminum frame. Contractor orders the wrong material.
Drawing shows 6½" mullion profile depth, specification requires 4½". Which one gets fabricated?
Detail shows #10 fastener, but specification calls for different fastener type. Installation fails or requires rework.
Drawing notes one finish, specification calls out different finish. Results in visible aesthetic issues.
On a commercial project, AI plan review checked the drawings against a 2,000-page specification book and found over 200 conflicts. Examples included:
| Element | Drawing says | Spec says |
|---|---|---|
| Storefront framing | 5½" x 3¾" | 4½" x 2" |
| Frame material | Hollow metal | Aluminum |
| Mullion depth | 6½" | 4½" |
| Glazing system | Standard | Thermally broken |
Each of these conflicts would have resulted in an RFI during construction. With 200+ conflicts, that's potentially hundreds of hours of RFI processing time, and significant risk of wrong material being installed.
AI plan review reads both the drawings and the specification book, then cross-references every element. For each conflict found:
This allows the design team to resolve conflicts before issuing documents for construction, reducing RFIs and rework.
