Send us the CD set. We map what's fire-rated, pin every pipe, duct and sprinkler line through it, double-check each pin, then walk the job weekly and keep the status current until the agency signs off.
Detail D4 · 1-hr wallFive steps, the same on every job. Nothing is pinned until the rated walls and floors are settled.
You send the CD set, revisions and specs. We log every sheet and flag what's missing.
We work out what's fire-rated from your set's own code sheet, life-safety plans and wall types. You approve the map.
Every penetration of a rated wall or floor gets a pin at the exact crossing, with trade, size and rating.
A second, blind pass re-reads the original drawings. Disagreements are tie-broken before anything is drawn.
Weekly walk, GC sign-off, agency acceptance. Numbered reports; the agency gets the final one.
Every architect marks ratings differently. We don't hard-code symbols; each set gets a drawing profile, and every pin is backed by the source it came from.
CAD-exported PDFs, scanned sets with OCR, and DWG or Revit where they're released.
MEP sheets are aligned to the plans by grid or by geometry, and crossings with rated walls are calculated, not eyeballed.
Clean crops of the original sheets, re-read without the pins, then reconciled. Inferred calls stay "check in field".
Code sheet, life-safety plans, wall-type tags and damper tags are cross-checked. Conflicts go to the GC as questions.
F rating for walls, F+T for floors (IBC 714), L for smoke barriers; dampers tracked as opening protectives.
Destructive-test coverage per type and area, failures flagged, every status with its source and date.
