NEC Mechanical Compliance Check

AI-powered National Electrical Code (NFPA 70) compliance checking for mechanical construction drawings. Detect violations, missing requirements, and code compliance issues before they delay your permit or hit the field.

About National Electrical Code (NFPA 70)

The US standard for electrical installations including wiring, overcurrent protection, grounding, and equipment. Adopted by most jurisdictions as the basis for electrical code enforcement.

Scope

Electrical installations in all building types

Editions

2023 NEC, 2020, 2017, 2014

Applicability

Adopted in nearly all US jurisdictions. Some states lag by one or two editions.

What We Check For

NEC compliance checking for mechanical drawings

Cross-reference mechanical details against National Electrical Code (NFPA 70) requirements

Verify mechanical specifications meet NEC minimum standards

Check mechanical coordination against NEC referenced standards

Identify mechanical issues that could cause NEC compliance failures

Review mechanical drawings for common NEC violations

Common Mechanical Issues We Catch

HVAC, exhaust, ventilation, and refrigeration drawings.

Outdoor air ventilation rate calculation errors (ASHRAE 62.1)

Duct sizing and static pressure calculation mismatches

Equipment clearance and access deficiencies

Exhaust system termination proximity to intakes

Kitchen hood makeup air deficiencies

Smoke control system design gaps

Energy code compliance — equipment efficiency and controls

Why NEC Mechanical Compliance Matters

National Electrical Code (NFPA 70) compliance for mechanical drawings is critical because violations discovered during plan review delay permits, and issues found during construction result in costly rework, change orders, and schedule delays. Catching NEC mechanical issues during preconstruction costs 10x less than fixing them in the field (CII, 1-10-100 Rule).

How Articulate Checks NEC Compliance

Upload Your PDF Drawings

Upload your mechanical PDF drawings. No BIM models or 3D software required — Articulate works with the 2D PDFs your team already uses.

Purpose-Built Construction AI

Articulate's AI is trained specifically to review construction drawings against NEC requirements. Domain-specific training catches issues that generic AI tools miss.

Exact Issue Locations

Every NEC compliance issue is tagged with the exact page and coordinates on your drawings, plus severity ratings (high, medium, low) so you can prioritize.
