# 304 Whitson MEP Trade Review

**Issued:** 2026-08-20  
**Status:** BLOCKED — NOT CODE READY — NOT FOR CONSTRUCTION

## Purpose

This package gives plumbing, HVAC and electrical subcontractors isolated coordination views of the currently modeled scope. It identifies required design work, missing data and confirmed geometry conflicts.

It is not a permit set, fabrication model, bid quantity takeoff or code certification. Field verification, licensed design and Buncombe County/AHJ approval are required.

## Start here

1. `reports/304-whitson-mep-critical-code-screen-and-trade-views.pdf`
2. Open the PDF for your trade under `trade-pdfs/`.
3. Review the editable model under `model/` using the 15 cameras in `TRADE_REVIEW_CAMERAS`.
4. Return marked-up routes, equipment data, calculations, exclusions and unresolved field conditions.

## Critical stop-work findings

- About 88.81 ft of modeled gravity sanitary route is exactly level.
- MDP conflicts with the water heater and CW/HW piping.
- Wet exhaust conflicts with the sanitary stack.
- Electrical service geometry conflicts with plumbing and HVAC geometry.
- Repeated electrical lighting solids intersect HVAC terminal/duct solids.
- Commercial kitchen hood, grease duct, makeup air and suppression are not construction-designed.
- The modeled HOOD shaft is shared by the grease riser, MUA riser and plumbing vent. The grease enclosure must be grease-duct-only.
- The modeled grease interceptor is indoors. MSD review defaults new food-service establishments to an outdoor interceptor unless it approves an indoor exception in writing.
- Roof intake/exhaust clearances are unresolved; the wet-fan/MUA condition is likely deficient.
- Electrical load, one-line, panel, circuit, fault-current, grounding, working-clearance and energy-code lighting-control information is absent.

## Package contents

- `model/`: v5 Blender review model with packed texture, relative render path, embedded findings and 15 trade cameras.
- `reports/`: 24-page combined report/PDF, source-cited Markdown report and verbatim code evidence ledger.
- `trade-pdfs/`: five-sheet plumbing, five-sheet HVAC and five-sheet electrical sets.
- `views/`: all 15 full-resolution annotated PNG sheets.
- `contacts/`: one contact sheet per trade.
- `audit/verification-summary.json`: final counts and quantified findings.
- `file-manifest.json`: file sizes and SHA-256 hashes.

## Required approval path

Licensed trade designers and contractors must complete the calculations, schedules, routing, details and field verification listed in the report. A North Carolina licensed design professional must issue sealed construction documents where required. Buncombe County and the AHJ make the final code determination.
